    Description
    Title of the invention: U-shaped housing and cover for fin plate heat exchangers The invention relates to a heat exchanger intended for a vehicle, and more particularly to a housing configuration for a heat exchanger heat.
    As is well known, it is desirable that the air entering the engine of a vehicle is cooled, in particular after it has left a turbocharger or a supercharger, because the air coming from a cooler will have an increased density which maximizes the efficiency of the engine. In certain situations, air cooling can also facilitate engine management and eliminate the pre-detonation of air and fuel before a programmed spark ignition. In addition, air cooling prevents the engine block from excessive wear and heat damage.
    Heat exchangers such as water-cooled charge air coolers (WCAC) can be used in the vehicle to cool the air that has been compressed by the turbocharger or the charge compressor before it 'enters the engine. Typically, for application-specific needs such as space constraints in a vehicle, for example, WCACs use coolant from one or more sources and may include a heat exchange core with plates interposed between fins.
    Typically, the core of the heat exchanger is disposed inside a housing. The housing is coupled to an inlet tank configured to receive air to be cooled in the heat exchanger and an outlet tank configured to transport air cooled by the heat exchanger. However, disadvantageously, the housing can be complex or formed from multiple components, the number of which may be greater than or equal to three. The many components increase manufacturing and assembly costs. In addition, the multiple components are liable to leak at the joints between the multiple components constituting the housing.
    [0005] Consequently, there is a need in the art for a simple heat exchanger housing which is formed from a minimum of components so as to reduce the manufacturing and assembly costs, as well as the leaks.
    In accordance with the present description, a simple heat exchanger housing which is formed from a minimum of components so as to reduce the manufacturing and assembly costs, as well as leaks is described.
    According to a first embodiment of the invention, a housing intended for a heat exchanger is described. The housing has a first housing part having a U-shaped cross section and a second housing part cooperating with the first housing part to define an enclosure receiving a heat exchange assembly. The second housing part is configured in the form of a plate.
    In addition, the first housing part has a flange extending outwardly from an outer surface at each of the opposite ends thereof. The second housing portion has a lip extending outward from a surface at each of the opposite ends thereof. The flanges of the first housing part and the lips of the second housing part cooperate to define a frame configured to couple on at least one element from a base and a reservoir. In addition, a tab extends outward from an engagement surface of the frame.
    The first housing part and the second housing part are formed from aluminum or plastic and are coupled by a soldering process, a welding process or a crimping process.
    According to another embodiment of the invention, a core assembly for a heat exchanger is described. The core assembly includes a two component housing including a first housing portion and a second housing portion cooperating to define an enclosure with a first open end and a second open end. A heat exchange set is received in the enclosure.
    In addition, the heat exchange assembly includes a plurality of sets of plates interposed between a plurality of fins.
    The first housing part has a substantially U-shaped cross section and the second housing part is substantially planar.
    The first housing part has a flange extending outward from a surface thereof at an end of the first housing part.
    The second housing part has a lip extending outward from a surface thereof, the lip cooperating with the flange to define a frame configured to couple on at least one of a base and a tank of the heat exchanger.
    In addition, the first housing part has a tongue extending outwards from an engagement surface of the flange, the tongue being configured to align an element among a base and a reservoir of the 'heat exchanger.
    The first housing part and the second housing part are formed from aluminum or plastic.
    According to yet another embodiment of the invention, a heat exchanger intended for a vehicle is described. The heat exchanger includes a core assembly having a first open end and a second open end. The core assembly includes a housing receiving a heat exchange assembly. The housing is formed of a first substantially U-shaped housing part and a second substantially planar housing part. A first reservoir is coupled to the first open end of the core assembly. A second reservoir is coupled to the second open end of the core assembly.
    In addition, the heat exchanger comprises a base disposed between the first reservoir and the core assembly and between the second reservoir and the core assembly.
    At least one element among the base, the first tank, and the second tank is welded, brazed or crimped on the core assembly.
    The first housing part has a flange disposed at each end thereof, the flange extending outwardly from an outer surface thereof, where the second housing part has a lip disposed at each end thereof, the lip at each end extending outward from a surface of the second housing part, and where the flange at each end cooperates respectively with the lip at each end to forming a frame configured to engage with an element from the first tank, the second tank, and a base.
    A plurality of tabs extend outward from an engagement surface of the flange, the tabs being configured to align an element among the first reservoir, the second reservoir, and the base on the housing.
    The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:

    The following detailed description and the accompanying drawings describe and illustrate various embodiments of the invention. The description and drawings are intended to enable those skilled in the art to make and use the invention, and are not intended to limit the scope of the invention in any way. With regard to the methods described, the steps presented are given by way of example, and thus, the order of the steps is not compulsory or critical. As used herein, the term "substantially" means "primarily, but not perfectly" or "approximately", as one skilled in the art will recognize from the description and the drawings.
    Figure 1 illustrates a heat exchanger 10 according to an embodiment of the invention. As illustrated, the heat exchanger 10 is configured as an intercooler, such as a water-cooled charge air cooler, for example. However, it is understood that the heat exchanger 10 can be configured into any type of heat exchanger commonly used in vehicle systems, such as an air-cooled charge air cooler, a tubular type heat exchanger, a radiator, an oil cooler, or any other heat exchanger known at present or developed in the future. The heat exchanger 10 includes an inlet tank 12 and an outlet tank 14 respectively intended to receive and convey air coming from an air circuit of a vehicle. The heat exchanger 10 further includes conduits 17 which are in fluid communication with openings, such as fluid inlets and outlets, for conveying a fluid to or from the heat exchanger 10. The fluid can for example be a coolant, a refrigerant, water or any other fluid configured to exchange heat with the air circulating in the heat exchanger 10.
    As shown in Figures 2 to 5, the heat exchanger 10 further includes a core assembly 15 disposed between the inlet tank 12 and the outlet tank 14. The core assembly 15 has a first open end 15a configured to receive air from the inlet reservoir 12 which will circulate in the heat exchanger 10. A second open end 15b is opposite to the first open end 15a and is configured to route the air having circulated in the heat exchanger 10 to the outlet tank 14. The core assembly 15 includes a heat exchange assembly 16 configured to transfer heat between the air flowing in the heat exchanger 10 and the fluid. In some embodiments, as shown, the core assembly 15 further includes a pair of sockets 19. Each of the sockets 19 is configured to facilitate coupling, respectively, of the inlet reservoir 12 and the reservoir outlet 14 on the core assembly 15. However, it is understood that the core assembly 15 can be coupled to each of the inlet 12 and outlet 14 reservoirs directly without the bases 19. Although not shown, from other components such as seals can be positioned between the inlet reservoir 12 and the core assembly 15, and between the outlet reservoir 14 and the core assembly 15, if desired.
    The heat exchange assembly 16 is disposed in a housing 18 of the core assembly 15. The heat exchange assembly 16 includes a plurality of substantially parallel and stacked plate assemblies 22. The sets of plates 22 are interposed between a plurality of substantially parallel fins 20. Each of the sets of plates 22 defines at least one flow channel (not shown) intended to receive the fluid from at least one external source. It is understood that other fluid delivery mechanisms can be used in place of the plate assemblies 22. For example, tubes can be used in place of the plate assemblies 22. Other delivery mechanisms fluid can be used as desired.
    The housing 18 shown is a multi-component housing formed from a pair of components called first housing part 24 and second housing part 26. The first housing part 24 and the second housing part 26 cooperate l with each other to define an enclosure intended to receive the heat exchange assembly 16. It is understood that other housing configurations can be used to enclose and receive the heat exchange assembly as desired . The first housing portion 24 has a substantially U-shaped cross section including a first wall 28 and a pair of second walls 30. The second walls 30 extend outward from an interior surface 54 of the first wall 28 at opposite sides of the first wall 28 and substantially perpendicular to the first wall 28. The second walls 30 extend substantially parallel to a direction of air circulation through the heat exchanger 10, which is represented by an arrow. The second walls 30 form closed sides of the core assembly 15.
    A pair of flanges 34 is coupled to the first housing part 24 of the housing 18, where a first flange of the pair of flanges 34 is formed at the first open end 15a and the second flange of the pair of flanges 34 is formed at the second open end 15b. The flanges 34 frame or define part of the openings at the respective end from the first open end 15a and the second open end I5b. In the illustrated embodiment, the flanges 34 are substantially U-shaped to correspond to the shape of the first housing part 24. The flanges 34 can be formed separately from the first housing part 24 and then be coupled thereto. by a fixing means such as a soldering or welding process, for example, or the flanges 34 can be formed integrally with the first housing part 24. Each of the flanges 34 cooperates with a respective lip 46 formed on the second housing part 26 of the housing 18, which will be described in more detail below, to form a frame or support 48 configured to engage with the base 19 or with one of the reservoirs 12, 14.
    The flanges 34 have a substantially planar engagement surface 36 to facilitate the engagement of the flanges 34 on the base 19 or on one of the tanks 12, 14 for a welding or brazing operation, for example. In the illustrated embodiment, the outer perimeter 38 of the flanges 34 extends outwardly from an outer surface 25 of the first housing portion 24 of the housing 18. Tabs 40 are formed along the perimeter 38 flanges 34 to facilitate alignment and positioning of the base 19 or one of the reservoirs 12, 14 on the housing 18 before welding or the brazing operation. The tongues 40 extend outward from the engagement surface 36 of the flanges 34 and substantially perpendicular thereto. Three of the tabs 40, one at each lateral side of each of the flanges 34 and one at a portion of each of the flanges 34 extending from the first wall 28 of the first housing part 24 are shown. However, more than three or less than three tabs 40 can be included if desired.
    A plurality of openings 32 is formed through the first wall 28 of the first housing part 24. The openings 32 are configured to ensure fluid communication between the conduits and the heat exchanger 10. The openings 32 ensure fluid communication of the fluid from the external fluid source with the enclosure formed by the first housing part 24 and the second housing part 26. It is understood that the openings 32 can be formed in other parts of the housing 18, as desired, as in the second walls 30 or the second housing part 26, for example.
    The second housing part 26 of the housing 18 is configured in the form of a substantially flat plate with the lip 46 disposed at each of the opposite ends of the second housing part 26. Each of the lips 46 extends towards the exterior from a surface 50 of the second housing part 26 substantially perpendicular to the surface 50. As mentioned above, each of the lips 46 cooperates with a respective flange among the flanges 24 to form the frame 48. The second part of housing 26 has a width slightly less than the width between the interior surfaces 54 of the second walls 30 of the first housing portion 24, where the side edges of the second housing portion 26 abut against the interior surfaces 54 of the second walls 30 of the first housing part 24. The first housing part 24 has a length substantially equal to the length of the second part of b housing 26.
    The frame 48 is substantially rectangular to engage with the base 19 which is substantially rectangular or with the reservoir 12, 14 which is substantially rectangular. However, the frame 48 may have other shapes as desired to facilitate engagement with the base 19 and / or a reservoir 12, 14 having another shape.
    The tongues 40 facilitate the alignment and the engagement of the base 19 or of the reservoir 12, 14 on the frame 48, and consequently on the core assembly 15.
    Once aligned and engaged with the core assembly 15, the base 19 or the reservoir 12, 14 is fixed to the frame 48 by a coupling means such as a brazing process, a welding process or a crimping. However, other coupling means such as fixings, bolts, screws, clamps or other coupling means can be envisaged, if desired.
    The components of the housing 18 (i.e. the first housing portion 24 and the second housing portion 26) can be formed from any material or any process, such as wish. In a first example, the first housing part 24 and the second housing part 26 are formed from aluminum by a stamping or casting process. In another example, the first housing portion 24 and the second housing portion 26 of the housing 18 are formed from a plastic material by a plastic forming process such as a molding process or a extrusion. However, it is understood that the first housing portion 24 and the second housing portion 26 of the housing 18 can be formed from any material or any process, as desired. The first housing part 24 is coupled to the second housing part 26 by a coupling means such as a soldering process, a welding process or a crimping process. However, bolts, screws, clamps or other coupling means can be considered, if desired.
    To assemble the core assembly 15, the heat exchange assembly 16 is received in the first housing part 24, where the first housing part 24 partially covers the heat exchange assembly 16. The second housing part 26 cooperates with the first housing part 24 to form the housing 18 in order to enclose the heat exchange assembly 16 to form the housing 18 and define the first open end 15a and the second open end 15b of the core assembly 15. The lateral edges of the second housing part 26 engage with the respective surfaces among the interior surfaces 54 of the second walls 30 of the first housing part 24. The lips 46 of the second housing part housing 26 aligns with the flanges 34 to form the frames 48. Once the second housing part 26 is positioned in cooperation with the first housing part 24, the first housing part 24 is coupled to the second housing part 26 by the coupling means.
    According to a first embodiment of the invention, the reservoirs 12, 14 are directly coupled to the core assembly 15 by the coupling means. In another embodiment, the bases 19 are directly coupled to the core assembly 15 by the coupling means and disposed between the reservoirs 12, 14 and the core assembly 15. The tongues 40 are configured to align and engage on tanks 12, 14 or sockets 19 before coupling. Once aligned and engaged, the reservoirs 12, 14 or the bases 19 can then be brazed, welded, or otherwise coupled by the coupling means on the frames 48.
    Advantageously, the heat exchanger 10 according to the present invention limits the number of components required to form the housing 18 of the heat exchanger 10, to less than four components, and more specifically, to two components, as described here. Furthermore, since only two components form the housing 18, there are fewer soldering, welding or coupling interfaces between the components of the housing 18 than for the prior art housings intended for heat exchangers . As a result, there are fewer mating interfaces that can lead to leakage. In addition, the heat exchanger 10 of the present invention reduces manufacturing costs and complexity.
    According to the preceding description, the skilled person can easily determine the essential characteristics of the present invention and, without departing from his spirit and scope, can make various changes and modifications to the invention for adapt it to various uses and conditions.
