    LIQUID HEAT EXCHANGER FOR REFRIGERANT AND METHOD OF OPERATION OF THE SAME
    BACKGROUND [001] It is known that liquid to refrigerant heat exchangers are used to transfer thermal energy between a flow of refrigerant and a flow of liquid cooling fluid. Such a heat exchanger can be used as a cooler heat exchanger, in which the heat from a stream of liquid cooling fluid is transferred to a refrigerant to thereby vaporize the refrigerant, resulting in a cooled flow of liquid cooling fluid. that comes out of the heat exchanger. Alternatively, such heat exchangers can be used as a condenser, in which the heat from a superheated refrigerant flow is transferred to a liquid cooling fluid cycle to thereby cool and condense the refrigerant.
    [002] Refrigeration systems and vehicular air conditioning have traditionally used air-cooled condensers to perform and the cooling and condensation of the superheated refrigerant that comes out of the refrigerant system compressor. Such an air-cooled condenser is typically arranged at the front of the vehicle in order to receive the necessary air flow, which can be provided by the vehicle's propulsion itself, or by an air handling device, or both. Certain advantages can be obtained, however, by using a liquid-cooled condenser instead to accomplish this task. For example, the packaging of the engine compartment can be simplified by removing the
    2/27 condenser at the front end of the vehicle.
    [003] Challenges are also associated with the implantation of a liquid-cooled refrigerant condenser in such an application, however. The temperature of the liquid coolant cycle in a vehicle is necessarily higher than the ambient air temperature, so the head pressure of the refrigerant compressor needs to be increased in order to achieve the same amount of subcooling of the refrigerant. as previously achieved with the use of an air-cooled condenser. Adequate sub-cooling is important in reducing the total energy consumption of such a system, since it increases the specific enthalpy available from the refrigerant flow in the system evaporator.
    [004] An additional challenge is found in the implantation of an integrated receiver inside the system condenser. A receiver is typically located along the refrigerant flow path between a condenser section and a condenser sub-cooler section, and works to ensure that only liquid refrigerant is supplied to the expansion device that is typically placed , directly upstream of a system evaporator. Excess refrigerant is stored inside the receiver in both a liquid and vapor state, thereby preventing the condenser from overflowing with excess liquid refrigerant, which can reduce operating efficiency. As shown and described in US Patent No. 5,934,102, to DeKuester et al., Such a receiver is readily integrated into an air-cooled condenser as an additional cylindrical structure
    3/27 disposed adjacent to one of the cylindrical refrigerant tanks.
    [005] Such integration of the receiver is more difficult with a liquid-cooled condenser constructed as a plate-style heat exchanger. Published patent application US No. US2014 / Q224455 and published international patent application No. WO2014 / 085588 (both of the present applicant) show modalities of a liquid-to-refrigerant heat exchanger with such an integrated receiver. In these applications, a separate refrigerant line extends from the condenser section of the heat exchanger to the receiver. This separate refrigerant line can add manufacturing cost and complexity. Therefore, there is still room for improvement.
    SHORT DESCRIPTION [006] In accordance with an embodiment of the invention, a liquid to refrigerant heat exchanger includes a stack of nested plates with defined fluid flow passages between the plates. The stack of nested plates extends in a stacking direction between a top end and a bottom end of the stack, with a first subset of the stack adjacent to the top end that defines a condenser portion, and a second subset of the adjacent stack to the bottom end that defines a sub-refrigerator portion. A cover plate is attached to the top end of the stack and has a refrigerant inlet port attached to it to receive a flow of refrigerant in the condenser portion. A base plate is attached to the bottom end of the stack and has a refrigerant outlet port attached to it at the
    4/27 opposite the stack of nested plates. A receiver bottle is also attached to the base plate on the opposite side of the stack. At least a first and a second structural connection connect the receiving flask to the base plate. A first receiver flow path extends through the first structural connection to allow fluid flow between an internal volume of the receiver bottle and the condenser portion. A second receiver flow path extends through the second structural connection to allow fluid flow between an internal volume of the receiver bottle and the sub-chiller portion.
    [007] In some embodiments, the liquid to refrigerant heat exchanger includes a refrigerant collector that extends through the sub-refrigerator portion and is hydraulically insulated from it. The refrigerant collector provides a portion of the first receiver flow path.
    [008] In some embodiments, the heat exchanger includes a first, second and third refrigerant collector. The first refrigerant collector is arranged in a first corner of the stack of nested plates, extends through only the condenser portion, and is fluidly coupled to the refrigerant inlet port to receive the refrigerant flow. The second refrigerant collector is disposed in a second corner of the stack, extends through only the condenser portion, and is connected to the first refrigerant collector through some of the fluid flow passages defined between the plates of the condenser portion. The third refrigerant collector extends through the sub5 / 27 cooler portion and is hydraulically isolated from it, and provides a portion of the first receiver flow path.
    [009] In some such embodiments, a first liquid collector is disposed in a third corner of the stack, and a second liquid collector is disposed in a fourth corner of the stack. The first and second liquid collectors are connected by some of the fluid flow passages defined between the plates in both the condenser portion and the sub-refrigerator portion. In some such embodiments, the third coolant collector is displaced from the first, second, third and fourth corners.
    [010] In some embodiments, a fluid transfer plate is provided in the space between a first between the nested plates and an adjacent second between the nested plates. The first of the nested plates defines an end of the condenser portion and the second of the nested plates defines an end of the sub-refrigerator portion. A fluid transfer duct within the fluid transfer plate extends between the second and third refrigerant collectors to provide a portion of the first receiver flow path.
    [011] In some of these modes, the heat exchanger additionally includes a fourth and a fifth refrigerant collector. The fourth refrigerant collector is disposed in the first corner of the stack of nested plates, extends through only the sub-cooler portion, and is fluidly coupled to the second flow path of the receiver to receive the refrigerant flow. The fifth collector of
    6/27 refrigerant is disposed in the first corner of the stack of nested plates, extends through only the sub-refrigerator portion, and fluidly attaches to the refrigerant outlet port to deliver the refrigerant flow. The fourth and fifth refrigerant collectors are connected by some of the fluid flow passages defined between the plates in the sub-refrigerator portion. In some such embodiments, the second and fifth refrigerant collectors are fluidly isolated from each other by the second of the nested plates.
    [012] In some embodiments, the liquid-to-refrigerant heat exchanger includes a plurality of inserts arranged between at least some of the plates nested in the sub-refrigerator portion to at least partially define the third refrigerant collector.
    [013] According to another embodiment of the invention, a method of operating a liquid-to-refrigerant heat exchanger to cool and condense a gaseous refrigerant includes receiving a flow of liquid cooling fluid into the heat exchanger, directing a first portion of the flow through a condenser section of the heat exchanger, and direct a second portion of the flow through a sub-cooler section of the heat exchanger parallel to the first portion. The gaseous refrigerant is received in the heat exchanger and is directed through the condenser section in order to cool and at least partially condense the gaseous refrigerant by transferring heat to the first portion of the liquid cooling fluid stream. The at least partially condensed refrigerant is conducted to a
    7/27 receiver flask integrated with the liquid-to-refrigerant heat exchanger by transporting the refrigerant through a flow duct arranged at least partially within the sub-refrigerator section. The at least partially condensed refrigerant is separated into a portion of liquid phase refrigerant and a portion of gas phase refrigerant. The liquid phase refrigerant portion is directed through the sub-refrigerator section in order to further cool the liquid phase refrigerant by transferring heat to the second portion of the liquid cooling fluid flow. The liquid phase refrigerant is removed from the heat exchanger, and the first and second portions of the liquid cooling fluid are recombined and removed from the heat exchanger.
    [014] In some embodiments, conducting the at least partially condensed refrigerant to a receiving flask includes, first, directing the refrigerant through a first portion of the flow conduit disposed between the condenser section and the sub-refrigerator section, then direct the refrigerant through a second portion of the flow conduit. In some such embodiments, the refrigerant is directed through a third portion of the flow conduit that extends through a structural connection of the receiving flask after having been directed through the first and second portions of the flow conduit.
    [015] According to another embodiment of the invention, a liquid to refrigerant heat exchanger includes a stack of nested plates with defined fluid flow passages between the plates. Each of the plates has a generally rectangular shape, and each of the plates is
    8/27 with corner openings in at least some of the corners. A first liquid collector that extends at the height of the stack is defined by corner openings aligned at a first corner of the plates, and is in fluid communication with a first liquid port arranged at a first end of the stack. A second liquid collector that extends at the height of the stack is defined by corner openings aligned at a second corner of the plates, and is in fluid communication with a second liquid port at the first end of the stack. A first refrigerant collector that extends over a first portion of the stack from the first end is defined by corner openings aligned at a third corner of the stack, and is in fluid communication with a refrigerant inlet port at the first end of the stack. battery. A second refrigerant collector that extends over the first portion of the stack from the first end is defined by corner openings aligned in a fourth corner of the stack. A third refrigerant collector that extends over a second portion of the stack from a second end of the stack opposite the first end is defined by corner openings aligned at the third corner. The second portion of the stack is not coextensive with the first portion of the stack. A fourth refrigerant collector extends over the second portion of the stack from the second end, and is defined by corner openings aligned in the fourth corner. A refrigerant outlet port is arranged at the second end of the stack, and is in fluid communication with the fourth refrigerant collector. A fifth refrigerant collector extends
    9/27 on the second portion of the stack, and is moved from each of the first, second, third and fourth corners.
    [016] In some embodiments, the fluid flow passages defined between the plates include a first, a second, a third and a fourth plurality of flow passages. The first plurality extends between the first and second refrigerant passages, and the second plurality extends between the third and fourth refrigerant collectors. The third plurality is interspersed with the first plurality and extends between the first and second liquid collectors, and the fourth plurality is interspersed with the second plurality and also extends between the first and second liquid collectors. In some such embodiments, the fifth refrigerant collector extends through both the second and fourth plurality of fluid flow passages, and remains fluidly isolated from these flow passages.
    [017] In some embodiments, the fluid transfer plate is provided in the space between a first between the nested plates and a second adjacent one between the nested plates. The first nested plate partially defines a fluid flow passage of both the first and third plurality of fluid flow passages, and the second nested plate partially defines a fluid flow passage of both the second and fourth plurality of passages fluid flow, a fluid transfer duct within the fluid transfer plate provides fluid communication between the second and fifth refrigerant collectors. In
    10/27 some such modalities, the second among the plates is devoid of a corner opening in the fourth corner of the plate and, thus, isolates the second and fourth refrigerant collectors from each other.

    DETAILED DESCRIPTION [028] Before any modality of the invention is explained in detail, it should be understood that the invention is not limited, in its application, to the details of construction and the arrangement of the components set out in the description below or illustrated in the drawings in attachment. The invention can comprise other modalities and can be practiced or carried out in several ways. It should also be understood that the phraseology and terminology used in the present invention are for the purpose of description and should not be considered as limiting. The use of which includes, understands, or has and variations thereof in this document is intended to cover the items listed since then and their equivalents, as well as additional items. Unless otherwise specified or limited, the terms assembled, connected, sustained, and coupled and variations thereof are widely used and cover both direct and indirect assemblies, connections, supports and couplings. In addition, connected and coupled are not restricted to physical or mechanical connections or couplings.
    [029] A liquid heat exchanger for refrigerant 1, according to some embodiments of the invention, is shown in Figures 1 to 5. The heat exchanger 1 may be especially suitable for rejecting the heat from a refrigerant stream in the high pressure of a vapor compression refrigerant circuit through condensation and subcooling of the high refrigerant
    12/27 pressure between a compressor and an expander of such a system. The heat exchanger 1 may be of particular use in climate conditioning systems found in automobiles and other transport vehicles by transferring compactly and efficiently the residual heat from the refrigerant to a liquid cooling fluid cycle traditionally found in such vehicles.
    [030] The heat exchanger 1 is constructed to include a stack 2 of nested plates or linings 3 formed from sheet metal material (for example, aluminum). Such a construction can produce a compact heat exchanger and relatively light weight, while still allowing for the heat transfer efficiency and structural strength required to withstand the extreme pressures that can be associated with the high pressure side of the refrigerant circuit.
    [031] The stack 2 of nested plates 3 is joined by end plates 14 arranged at either end of the stack 2. End plates 14 are, in general, of a similar construction to other nested plates 3, with similar nesting features as will be described, but they can be constructed with a greater material thickness to provide sufficient structural support and pressure functionality. A cover plate 13 is attached to the top side end plate 14, and a base plate 4 is attached to the bottom side end plate 14. Note that, although reference is made in this document to a top side and bottom side for easy description, heat exchanger 1 is not limited to a
    13/27 installation orientation in which stack 2 is arranged vertically with the so-called top side located above the so-called bottom side. The heat exchanger 1 can alternatively be operated in other orientations, such as with the stack plate 2 extending horizontally, for example.
    [032] The first and second liquid ports 12 are attached to the cover plate 13 at opposite corners of the stack 2, and provide an inlet and outlet for a liquid coolant flow to be used as a heat transfer medium. on the heat exchanger 1. Additionally, a coolant fitting 6 is attached to the cover plate 13 in a third corner of the stack 2. Cover plate 13 of the exemplary embodiment is a separate plate that is attached to the top side end plate 14, but in some embodiments, cover plate 13 may be integral with that end plate 14. In any case, openings for receiving (and / or communicating fluidly with) liquid ports 12 and the coolant fitting 6 are provided on cover plate 13.
    [033] The bottom side end plate is assembled and joined to the base plate 4, which is constructed as a flat plate that has an outer periphery that is somewhat larger than the outer periphery of the end plate 14. In the example mode , the base plate 4 is constructed from two joined plates 4a and 4b, although, in other embodiments, the base plate 4 can be constructed from a single plate.
    [034] A receiver bottle 5 is attached to the base plate 4 on the opposite side of stack 2. The receiver bottle 5 has a shape,
    14/27 generally cylindrical, extending longitudinally parallel to the base plate 4. A removable cover 28 is provided at an open end of the receiving bottle to provide an enclosed internal volume 47 therein. During the operation of the system, the refrigerant that is condensed within the heat exchanger 1 is received and stored within the internal volume 47, with the refrigerant being contained within it, generally, in a saturated state. The liquid phase refrigerant is extracted from the receiver bottle 5 and sub-cooled inside the heat exchanger 1 before being delivered to a refrigerant circuit expansion valve. Although not shown, a desiccant material can optionally be supplied within the internal volume 47 to remove moisture from the refrigerant.
    [035] A second refrigerant fitting 6 is also attached to the base plate 4 on the side opposite the stack 2. This second refrigerant fitting 6 provides an outlet port 8 for the refrigerant, while the first refrigerant fitting 6 mentioned earlier. (attached to cover plate 13) provides an inlet port 7 for the refrigerant (best seen in Figures 3A and 3B). When installed in a refrigerant system, refrigerant lines 11 equipped with claws 9 are sealingly joined to the fittings 6 with the use of gripping screws 10 in order to connect the liquid to refrigerant heat exchanger to a cooling circuit. refrigerant in a sealed manner and, in general, free from leaks.
    [036] The nested plates 3 have a generally rectangular design, and the receiving bottle 5 is oriented so that the axial direction of the bottle 5 extends
    15/27 parallel to the long edges of the rectangular plates 3. The central axis of the bottle 5 is arranged so that it is directly under the refrigerant inlet port 7 and one of the liquid ports 12, the one being one of the ports of liquid 12 is located along a common long edge of the plates 3 with the refrigerant inlet port 7. Therefore, space is provided for the refrigerant fitting 6 that contains the refrigerant outlet port 8 to be disposed to the side of the receiving bottle 5 in a location that corresponds to that corner of the stack 2 that is diagonally opposite the corner where the refrigerant inlet port 7 is located.
    [037] Turning now to Figures 5 and 6, the features of the nested boards 3 and the stack board 2 will be described in more detail.
    [038] Each of the nested plates 3 is joined by a continuous upward flap edge 38 arranged at a slightly obtuse angle to the flat base of the plate. These edge flaps 38 allow the adjacent plates to be nested in order to create a sealed perimeter along the outer surfaces of the stack 2, with the flat portions of the plates 3 spaced to define fluid flow passages between them. The refrigerant and liquid coolant passages are alternately interlaced, as will be described.
    [039] With certain exceptions that will be described in detail later, the nested plates 3 are all provided with openings 39 arranged in each of the four corners of the plate. The corner openings 39 are circumscribed by a formed edge 40 that extends in the opposite direction to the
    16/27 flat surface of the plate, with two diagonally opposite openings 39 having the formed edge 40 extending upwards in the same direction as the upward facing flap 38, and the remaining two diagonally opposite openings 39 of each plate 3 have the formed edge 40 extending in the opposite direction. The heights of the formed edges 40 are such that a formed edge 40 of a first between the plates 3 will engage with a formed edge 40 of a second adjacent between the plates 3 in two of the corners, thereby providing sealed joints within of the flow passage between the two plates in these two corners. The openings 39 in the remaining two corners are left open for the flow passage. The sealed joints are located at the alternating corners in the adjacent flow passages.
    [040] As shown in Figures 5 and 6, two adjacent nested plates 3a and 3b are provided at a specific location within pile 2 and serve to divide pile 2 into a first portion 16 and a second portion 17. The first portion 16 extends from the top end plate 14 to the plate 3a, while the second portion 17 extends from the bottom end plate 14 to the plate 3b. In the exemplary embodiment, the first portion 16 operates as a condenser, and the second portion 17 operates as a sub-refrigerator.
    [041] As best seen in Figure 6, some of the corner openings 39 are missing from plates 3a and 3b. Specifically, there is no corner opening 39 on plate 3a in the corner that corresponds to the location of the refrigerant inlet door 7, and there are no corner openings 39
    17/27 on the plate 3b in the corners that correspond to the locations of both the refrigerant inlet door 7 and the refrigerant outlet door 8. In addition, the corner opening 39 of plate 3a in the corner that corresponds to the location of the exit door of refrigerant 8 is supplied without the corresponding formed edge 40.
    [042] A fluid transfer plate 36 is provided in the space between the nested plates 3a and 3b. Matched corner openings 39 are provided on the fluid transfer plate 36 in at least the corners that correspond to the locations of the liquid ports 12 and the refrigerant outlet port 8. A fluid transfer duct 37 extends from the opening 39 in the corner of the refrigerant outlet port 8 to a central location within the fluid transfer plate 36.
    [043] The aligned corner openings 39 cooperate to define fluid collectors in each corner of the stack 2. In the exemplary mode of the liquid to refrigerant heat exchanger, a total of six such corner collectors are present. The first and second collectors 20 extend in opposite corners of the stack 2 all the way between the end plates 14, as can be seen best in Figure 4. Each of the collectors 20 is arranged in a corner directly under one of the doors. liquid 12, and is in fluid communication with them. One of the liquid collectors 20 functions as an inlet collector to receive a flow of liquid coolant 49 into the liquid to refrigerant heat exchanger 1 through one of the ports 12, and deliver
    18/27 this flow for liquid flow passages 27 arranged between some of the nested plates 3. The other one of the liquid collectors 20 functions as an outlet collector for collecting the flow of liquid cooling fluid from the flow passages 27 , and directs the liquid coolant out of the heat exchanger 1 through the other port 12.
    [044] A third collector 21 extends through section 16 of stack 2 in the corner that corresponds to the location of the refrigerant inlet fitting 6. As best seen in Figure 3A, the collector 21 is in direct fluid communication with the refrigerant inlet 6, and functions as a refrigerant inlet manifold to receive a refrigerant flow 31 through refrigerant inlet port 6 and to distribute that refrigerant flow to the refrigerant flow passages 25 arranged between some of the nested plates 3 in section 16 of stack 2. The refrigerant flow passages 25 are interspersed with those among the liquid flow passages 27 located within section 16, so that an efficient heat transfer between the refrigerant and the liquid coolant flowing in these passages can be achieved.
    [045] A fourth collector 22 extends through section 16 in the corner diagonally opposite the collector 21, and is in fluid communication with the flow passages 25 to receive the flow of refrigerant 31 therefrom. The fourth collector is additionally in fluid communication with the fluid transfer duct 37 provided on the fluid transfer plate 36.
    19/27 [046] A fifth collector 23 extends through section 17 of stack 2 and is aligned with collector 21, and a sixth collector 24 extends through section 17 and is aligned with collector 22. The absence of corner openings in the nested plates 3a and 3b, as well as in the fluid transfer plate 36, in the corner corresponding to the collectors 23, 21 provides the fluid insulation of these collectors, from each other. It must be understood, however, that such isolation can be achieved, in a similar way, by the absence of the corner opening in any one of these three plates. Similarly, the absence of a corner opening in the plate 3b in the corner corresponding to the collectors 22, 24 provides the fluid insulation of these collectors from each other.
    [047] The collectors 23, 24 are connected by flow passages 26 arranged between some of the nested plates 3 in section 17, these flow passages 26 being interspersed with those among the liquid flow passages 27 located within section 17 A flow of refrigerant 32 can be received in the collector 23 from the receiving flask 5 through a flow path of the receiver 19, so that the refrigerant 32 is placed in a heat exchange relationship with the liquid cooling fluid that passes through these flow passages 25 as it passes through the refrigerant flow passages 26. The collector 24 is in fluid communication with the refrigerant outlet port 8, so that the refrigerant flow 32 can be removed from the exchanger heat 1 after passing through section 17.
    [048] Fluid-permeable flow sheets, although not
    20/27 are shown in Figures 1 to 6, they can be included between the nested plates 3 to provide increased heat transfer to and from the fluids in flow passages 25, 26 and 27. A preferred example of such a flow sheet is a lanced and offset fin sheet 33, shown in Figure 10. The lanced and offset fin sheet 33 is formed from a thin sheet of metal that is perforated and formed to create convolutions 34 of a height that corresponds to the spacing between the nested plates 3. Openings 35 are formed in corrugation walls 34 to provide both increased flow piping and allow fluid flow in a direction perpendicular to the corrugations. The openings (not shown) can be formed in the sheets 33 at locations that correspond to the corner openings 39 to prevent interference with the engaged formed edges 40, and to allow unobstructed fluid flow through the corner collectors.
    [049] An additional refrigerant collector 50 extends through section 27 in a location that is not in a corner of stack 2, but instead is more centrally located within plates 3 of that portion of the exchanger of heat 1. The collector 50 is arranged along an imaginary straight line between the collector 21 and the opposite collector 20. The openings 41 in those among the nested plates 3 in section 17 of the stack 2, together, at least partially define the collector 50. The fluid isolation of the collector 50 from the flow passages 26 and 27 can be achieved by a formed relief 42 that surrounds the opening 41 in some of the nested plates 3, and by
    21/27 insertion elements formed 43 arranged between the plates 3 in adjacent layers, as shown in Figures 6 and
    7. The fin sheets 33 in section 17 can be released at the location that corresponds to the collector 50, as shown in Figure 7.
    [050] In some highly preferred embodiments, many of the components of the liquid to refrigerant heat exchanger are constructed from a weldable aluminum alloy, and are joined together in a furnace brazing operation. It can be particularly economical for stack 2 of nested plates 3, cover plate 13, base plate 4, fittings 6, ports 12 and receiver bottle 5 to be joined in a single brazing operation.
    [051] The internal volume 47 of the receiving flask 5 is in fluid communication with both the collector 50 and the collector 23 through flow openings 48 that extend through at least a part of the structural support 15 that joins the flask receiver 5 to the base plate 4. As best seen in the partially exploded view of Figure 5, the receiver bottle 5 includes three integral structural supports 15 that extend from the outer surface of the bottle 5 to a common flat surface. In the exemplary embodiment, the base plate 4 is constructed from a first plate, 4a, joined to a second plate, 4b. Such an arrangement may be specifically preferred in that cavities 51 can be provided in plate 4b to locate and receive structural supports 15, thereby ensuring that the receiving vial 5 is properly located in relation to the base plate 4. Similar results can be
    22/27 achieved with a one-piece base plate 4 in which the cavities extend only partially through the thickness of the base plate, but such an arrangement is likely to incur additional manufacturing costs.
    [052] The fluid transfer duct 37 described previously on the fluid transfer plate 36 extends between the collector 22 and the collector 50, and establishes a first flow path of the receiver 18 (shown in Figure 3A) to deliver the refrigerant which passed through the flow passages 25 to the internal volume 47 of the receiver vial 5. The first receiver flow path therefore includes the fluid transfer duct 37, the collector 50, and one of the openings 48. A second flow path Receiver flow 19 (shown in Figure 3B) includes the other opening 48 and the collector 23. A refrigerant flow 32 is extracted from the internal volume 47 of the receiving bottle 5 via flow path 19, and is directed along the flow passages 26 before being collected in the collector 24 and removed from the heat exchanger 1 through the refrigerant outlet port 8.
    [053] In a highly preferred embodiment, the first section 16 of the liquid-to-refrigerant heat exchanger 1 functions as a condenser section to substantially cool and condense refrigerant 31. Refrigerant 31 is collected in collector 22 and is directed through from the receiver flow path 18 to the internal volume 47 of the receiver vial. Under certain operating conditions, refrigerant 31 can be completely condensed, so that refrigerant 31 enters volume 47 in a saturated or slightly sub23 / 27 cooled liquid state. In other operating conditions, refrigerant 31 may be predominantly condensed into a liquid state, but it may still have some remaining vapor quality, so that it enters volume 47 in a two-phase state (liquid and vapor).
    [054] By transferring the refrigerant from the condenser section 16 to the receiver vial 5 through the flow path located internally 18, any need to conduct the refrigerant external to the stack 2 is avoided. This can beneficially avoid excessive costs associated with such a fluid conduction, as well as the complexity that is associated with the manufacture of a heat exchanger that uses such an external conduction.
    [055] The primary function of the receiving bottle 5 within the system is to provide a charge storage capacity within the internal volume 47. The internal volume 47 will generally contain refrigerant in both a liquid and a vapor state. , in varying proportions that are mainly determined by the amount of charge contained within the refrigerant system and the immediate operating conditions. Inclusion of receiver 5 prevents unwanted charge build-up
    excessive c section center of condenser in si, improving, thus, the performance of operation of exchanger heat 1. [056] A efficiency of performance system in soda is additionally optimized by the cooling of the soda liquid for a state in
    lower enthalpy before delivering the refrigerant to a system expansion device. In a
    24/27 highly preferred embodiment, section 17 of the liquid-to-refrigerant heat exchanger 1 is a sub-refrigerator section, and refrigerant flow 32 is a liquid refrigerant flow that is received from volume 47 and is sub-cooled as it passes through the flow channels 26 through heat transfer to the liquid cooling fluid flow that passes through the sub-cooler section 17. Proper separation of the refrigerant within the volume 47 into a liquid portion and a vapor portion (using, for example, gravity effects) can ensure that the refrigerant flow introduced into flow passages 26 through flow path 19 is in a completely liquid state.
    [057] Turning now to the design of collector 50, as can be seen better in Figure 7, it can be seen that, in each plate interspersed among the plates 3 within section 17, the relief 42 is formed in the direction opposite the flat surface of the plate 3 to a height that is approximately equal to the space between adjacent plates between the nested plates 3. A flat settlement that surrounds the hole 41 in these plates, therefore, makes contact with the flat surface of the adjacent plate, in so that a seal between the plates can be created at the location, for example, by brazing. The inserts 43 are placed between the plates in adjacent layers to provide the structural support and seal of the collector 50 of the flow paths in those layers. The inserts 43 are formed from flat metal sheets to a shape that is approximately equal in height between the adjacent plates, and
    25/27 are provided with a flat seating surface at both ends of the height in order to obtain a seal against both plates 3 that define the flow layer within which the insert 43 is placed. An opening 44 is provided in each of the insertion elements 43, and is in direct alignment with the opening 41 of the adjacent plate. The joints between the insert 42 and the flat surfaces of the plates can be produced at the same time as the joints between the reliefs 43 and their adjacent plates, for example, by brazing.
    [058] The alternating arrangement of reliefs 42 and insertion elements 43 can beneficially provide a structurally robust and leak-free column that surrounds the collector 50 so that the refrigerant flow can be efficiently transported from the condenser from liquid-to-refrigerant heat exchanger 1 to the receiver without the need to conduct external fluid to the heat exchanger 1. In a certain application, other types of heat exchanger 1 with different collector designs may be preferred and have been contemplated by the inventors. In such a design, the insert elements 43 are formed from a flat piece of material that has a thickness approximately equal to the desired spacing between the plates 3, so that the formation of the insert is no longer necessary. Such a design provides additional structural strength and stiffness, however, with a slightly higher weight penalty and possibly a higher cost.
    [059] An additional alternative design is illustrated in Figure 8, and includes a sleeve insert 45 that extends from the
    26/27 fluid transfer plate 36 to the base plate 4. This alternative design allows for the elimination of insertion elements 43, and can accommodate a smaller shoulder of the fin sheets 33 around the collector 5. Yet another alternative design is illustrated in Figure 9. In this project, the insertion elements 43 and the reliefs 42 have been completely removed. In its place, a tapered frusto-conical protuberance 52 is provided on each plate 3 at the location of the collector 50, with the openings 41 provided at the apex of the protuberances 52. The angle of the protuberance 52 is such that the protuberances 52 of adjacent plates 3 are nested in a manner similar to the edge flaps 38 of the plates, thereby providing the fluid seal required to isolate the manifold 50 from the flow paths 26 and 27 in section 17.

With the exception of features, elements and modes of operation that are mutually exclusive or inconsistent with each mode described above, it should be noted that the features, elements and alternative modes of operation described with reference to a specific mode are applicable to the other modes , [061] The modalities described above and illustrated in the Figures are presented by way of example only and are not intended to limit the concepts and principles of the present invention. As such, it will be understood by an individual of common skill in the technique that various changes in the elements and their configuration and arrangement
