[20] Typically, a vehicle air conditioner is configured with a cooling and heating system for cooling and heating the interior of a vehicle. The cooling system for cooling the interior of a vehicle pumps heat to the exterior of the vehicle while circulating the heat exchange medium by a conventional refrigeration cycle. [21] Referring to FIG. 1, the cooling system 10 includes a compressor 11, a condenser 12 connected to an outlet of the compressor, a receiver dryer 13 connected to an outlet of the condenser 12, and the condenser 12. Expansion valve 14 is connected to the rear portion of the flow direction of the) and the evaporator 15 is connected to the expansion valve (14). [22] In the cooling system 10 having the above structure, the compressor 11 receives the power of the engine as a V belt and compresses the heat exchange medium having a low temperature and low pressure. The condenser 12 condenses the heat exchange medium converted into a gaseous state of high temperature and high pressure by the compressor 11 to a liquid state of high temperature and high pressure. Next, the heat exchange medium passes through the receiver dryer 13 so as to absorb the moisture contained in the heat exchange medium, and reaches the evaporator 15 through an expansion valve 14 for rapidly expanding the heat exchange medium. In the evaporator 15, the heat exchange medium evaporates from the liquid state to the gaseous state. At this time, since the latent heat of evaporation lowers the ambient temperature, it is blown to the vehicle interior. [23] 2 shows a cooling system 20 according to another conventional embodiment. [24] Referring to the drawings, the cooling system 20 includes a compressor 21, a condenser 22 connected to the compressor 21, an orifice tube 23 connected to the condenser 22, and the orifice tube 23. ) And an accumulator (24) connected to the evaporator (25). [25] The cooling system 20 having the above structure compresses the heat exchange medium in the gas phase in the compressor 21 and then condenses it in the condenser 22. Subsequently, the heat exchange medium introduced into the evaporator 25 after being expanded at low pressure through the orifice tube 23 serving as the expansion means is evaporated from the liquid state to the gaseous state, and the gaseous heat exchange medium is returned through the accumulator 24 again. It is introduced into the compressor (21). [26] However, in the conventional cooling system, the expansion valve 14 or the orifice tube 23 is necessary to throttle and expand the liquid heat exchange medium from the condenser 12, 22 and send it to the evaporator 15, 25. Do. [27] For this purpose, Japanese Patent Laid-Open No. Hei 8-285407 discloses a configuration in which a throttle portion is formed in a tank cup portion so that a heat exchange medium flows without bias. However, the above configuration is for preventing the bias of the heat exchange medium only, and there is still a need for a separate drawing means in the cooling system. [28] Therefore, if the throttling means can be integrally installed in the evaporator, the structure of the refrigeration system can be simplified and the performance can be improved by shortening the path through which the heat exchange medium flows on the refrigeration cycle. [29] SUMMARY OF THE INVENTION The present invention has been made in view of the above problem, and an object of the present invention is to provide a condensing means integrated evaporator which simplifies the structure of a cooling system by installing an inflating means in an evaporator that absorbs and cools the surrounding heat.

[41] In addition, the inlet of the evaporation zone is in communication with the throttle distribution pipe, characterized in that the orifice pipe for lowering the pressure of the heat exchange medium is further installed. [42] Hereinafter, the throttling means integrated evaporator according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. [43] 3 shows an evaporator 30 according to a first embodiment of the invention, and FIG. 4 shows the throttling means 300 of FIG. [44] Referring to FIGS. 3 and 4, the evaporator 30 is formed by stacking molding plates 31 coupled to each other. One molding plate 31 is a pair of the front plate 32 and the back plate 33 coupled to the front plate 32. The forming plate 31 is preferably made of a steel plate-shaped aluminum plate. At least one tank part 34 through which the heat exchange medium is introduced and discharged is formed in upper and lower portions of the forming plate 31. A plurality of dimples 35 are formed inside the pair of forming plates 31 to promote turbulence of the heat exchange medium. In addition, a heat dissipation fan (not shown) is interposed between the forming plates 31 to improve heat exchange efficiency. [45] Here, throttling means is provided in a passage through which the heat exchange medium flows in the evaporator 30. That is, the throttling means 300 is provided at the inlet side of the evaporator 30 so as to throttle the incoming heat exchange medium. The throttling means 300 includes a front throttling plate 310 and a rear throttling plate 320 which is installed to face the front throttling plate 310. Between the front and rear throttling plate (310, 320) is provided with a pressure intensifying means 330 that can be fed into the evaporator 30 by the throttling action to lower the pressure of the heat exchange medium. [46] The pressure drop means 330 is provided with a pressure drop plate 331 of the steel sheet. The pressure drop plate 331 has a throttle flow passage 332 is formed. The throttle passage 332 has a capillary shape. The throttle passage 332 is a through-hole connected integrally over the entire surface of the plate 331, and is formed in a sand shape. [47] At least one communication hole 333 and 334 is formed in the pressure drop plate 331 in which the throttle passage 332 is formed. [48] That is, an inlet communication hole 333 is formed at an upper side of the pressure drop plate 331 in communication with an inlet pipe 36 that provides a passage of the heat exchange medium flowing into the evaporation region. The inflow communication hole 333 is preferably in communication with one end 332a of the throttle passage 332. [49] The other side of the pressure drop plate 331 is formed with a discharge communication hole 334 is inserted into the discharge pipe 37 for providing a passage for discharging the heat exchange medium heat exchanged through the evaporator (30). The discharge pipe 37 is connected to the evaporation region through the front and rear throttling plate 310, 320 and the pressure drop plate 331 interposed therebetween. [50] On the other hand, the rear throttling plate 320 is coupled to the outlet pipe 38 for providing a passage so that the heat exchange medium throttled through the pressure drop plate 331 is supplied to the evaporation region on one side thereof. The outlet pipe 38 preferably communicates with the other end 332b of the throttle passage 332. [51] The throttling means 300 having such a configuration arranges the front throttling plate 310 and the rear throttling plate 320 which are installed to face each other in a row, and the throttle passage 332 is formed in a meandering direction. It is manufactured by combining with each other while the falling plate 330 is inserted. In this case, the pressure drop plate 330 is coupled to the inlet pipe 36 and the outlet pipe 38 through which the heat exchange medium flows in and out so as to communicate with the throttle passage 332, and the heat exchange medium heat exchanged in the evaporation region. The discharge pipe 37 is discharged is inserted into the discharge communication hole (334). [52] Alternatively, a wire in which a throttle flow path is formed may be used as the pressure drop means. This wire can be sent to the evaporation zone while the pressure of the heat exchange medium flowing into the capillary shape having the thin hole is reduced. The wire may be communicatively coupled to the inlet pipe 36 through which the heat exchange medium is introduced, and the outlet pipe 38. [53] The evaporator 30 having an integral throttling means 300 having the structure as described above is operated as follows. [54] The liquid heat exchange medium flowing through the inlet pipe 36 flows through the capillary shape of the throttle flow passage 332, and the throttling action occurs. That is, each time the heat exchange medium passes through the portion with high resistance, it is throttled and expanded to reduce the pressure in the flow direction. As such, when the heat exchange medium passes through the throttle passage 332, the pressure decreases due to friction or resistance of the flow, and the enthalpy is kept constant. As a result, the heat exchange medium is changed to a low temperature, low pressure wet saturated vapor state. [55] The heat exchange medium changed to a low temperature and low pressure vapor state is flowed into the evaporation region of the plurality of forming plates 31 stacked through the outlet pipe 38 in communication with the throttle passage 332 of the pressure-enhancing plate 331. . The heat exchange medium introduced through the expansion process is changed into superheated steam through heat exchange with the air inside and outside the vehicle while passing through the forming plate 31. The air deprived of heat is changed to a low temperature and low humidity state, and the air is discharged to the interior of the vehicle by the blower to maintain the indoor environment of the vehicle comfortably. The heat exchange medium in the superheated steam state is discharged through the discharge pipe 37 and supplied to the compressor again. [56] 5 shows the throttling means 50 according to the second embodiment of the present invention. [57] Referring to the drawings, the throttling means 50 includes a front throttling plate 51 and a rear throttling plate 52 coupled to the front throttling plate 51. Between the front and rear mating plates 51 and 52, a material having a capillary flow path, for example, an extruded material 53, is inserted. [58] The extruded material 53 is provided with a plate 54 having a size that can be inserted into an inner space of the front and rear mating plates 51 and 52 coupled thereto. From both surfaces of the plate 54, front and rear partition walls 55 and 56 protrude in the longitudinal direction of the plate 54. A plurality of front and rear partition walls 55 and 56 are formed on both surfaces of the plate 54 at predetermined intervals along the longitudinal direction. [59] As a result, the plate 54 is provided with a plurality of front and rear axle flow passages 57 and 58 in a space between the front and rear bulkheads 55 and 56. The front and rear throttle flow passages 57 and 58 are formed between the front and rear bulkheads 55 and 56, and are a plurality of narrow passages such as capillaries. The portion where the throttling means 50 is installed is the inlet side of the evaporator 30 as in the first embodiment. [60] In the throttling means 50 having the configuration as described above, the liquid heat exchange medium supplied from the condenser is introduced into the upper and rear throttling plates 51 and 52, and the front and rear throttling plates 51 and 52. ) Is discharged to the lower portion of the front and rear throttling plate (51) (52) while the pressure is dropped while passing through the plate 54 formed with a plurality of front and rear throttle passage (57, 58) interposed between the It is fed to the evaporation zone. [61] 6 shows the throttling means 60 according to the third embodiment of the present invention. [62] Referring to the drawings, the throttling means 60 includes a front throttling plate 61 and a rear throttling plate 62 which is installed to be coupled to face the front throttling plate 61. A pressure drop means is provided between the front and rear throttle plates 61 and 62. [63] The pressure drop means is a pressure drop plate 63 made of a metallic material of a porous foam, for example, using aluminum foam (Al foam). The metal foam 63 of the foam form breaks the equilibrium state when the heat exchange medium is introduced to serve as an throttling role. [64] As such, the heat exchange medium introduced through the front throttle plate 61 is throttled and expanded in the foam-shaped metal material 63, and is discharged through the rear throttle plate 62 to be supplied to the evaporation region. [65] As mentioned in the first to third embodiments described above, a capillary throttle flow path, an extruded material having a plurality of partition walls formed therein, or throttling means having a porous foam metal material is provided on the side surface of the plate forming the evaporation region. Through the throttling action on the heat exchange medium flowing from the condenser, the pressure can be supplied to the evaporation zone while the pressure is reduced. Alternatively, by installing a throttling means in the evaporation zone, the heat exchange medium introduced through the primary throttling process can be directly re-exchanged with the air at the same time. [66] Fig. 7 shows the throttling means 70 according to the third embodiment of the present invention applying this method. [67] Referring to the drawings, the throttling means 70 is provided with a plurality of places where the heat exchange medium is introduced into the evaporation zone, and to reduce the pressure of the heat exchange medium in multiple stages in the evaporation zone. That is, the throttling means 70 includes a first throttling means 71 and a second throttling means 710 capable of re-throttling the heat exchange medium throttled from the first throttling means 71. [68] The first throttling means 71 includes an orifice tube 74 coupled through the inlet hole 73 formed in the plate 72 installed at the inlet of the evaporation region. The orifice tube 74 is formed with a pressure drop hole 75 along the inside thereof. The pressure drop hole (75) is formed by expanding the portion of the orifice tube (74) in which the heat exchange medium flows (74a), the portion of the heat exchange medium discharged from a predetermined portion along the longitudinal direction of the orifice tube (74) Up to 74b is condensed. [69] The second throttling means 710 includes a plurality of plates and pressure drop means interposed therebetween as described above in the first embodiment. That is, the front throttle plate 711 is provided behind the plate 72. The front throttle plate 711 is coupled to the rear throttle plate 712 which is installed to be opposite to the front throttle plate 711. The front and rear throttling plates 711 and 712 are substantially the same as a pair of forming plates installed in the evaporation region. [70] A pressure drop plate 713, which is a pressure drop means, is installed in the inner space formed between the front and rear cross-throwing plates 711 and 712. The pressure drop plate 713 is formed with a meandering flow passage 714. The throttle passage 714 has a capillary shape and is an integral through hole formed in the pressure drop plate 713. Alternatively, a metal material made of porous foam or capillary wire may be used as the pressure drop means. [71] In the throttling means 70 having the above configuration, the liquid heat exchange medium flowing from the condenser passes through the orifice tube 74 and is primarily throttled in a low-temperature low-pressure wet saturated vapor state. The first throttled heat exchange medium is introduced through the front throttle plate 711 and then passes through the throttle flow passage 714, whereby the pressure drops to be secondary throttled. The recondensed heat exchange medium is continuously supplied to the evaporation region through the rear throttling plate 712. At this time, during the secondary throttling, the throttling flow can be directly exchanged with the outside air at the same time as the throttling action on the throttle passage 714. [72] 8 shows the throttling means 80 according to the fourth embodiment of the present invention. [73] Referring to the drawings, the throttling means 80 is provided with a plurality of throttling so that the heat exchange medium is introduced into the evaporation zone, and the heat exchange medium in the evaporation zone can be throttled in multiple stages. That is, the throttling means 80 includes a first throttling means 81 and a second throttling means 810 capable of re-throttling the heat exchange medium throttled from the first throttling means 81. [74] The first throttling means 81 includes an orifice tube 82 capable of throttling liquid refrigerant. The orifice tube 82 is formed with a pressure drop hole 83 in the longitudinal direction along the inside thereof. The pressure drop hole 83 extends from the inlet 82a of the orifice tube 82 to a predetermined portion, and from this to the outlet 82b of the orifice tube 82. Accordingly, the heat exchange medium through the orifice tube 82 causes the throttling action while the pressure drops. [75] The second orifice means 810 is coupled to the orifice tube 82. That is, the second throttling means 810 includes a throttle distribution pipe 811 connected to the orifice pipe 82. The throttle distribution pipe 811 communicates with the tank 34 formed on the upper portion of the plate 31 in the evaporation region. The throttle distribution pipe 11 has a distribution hole 812 formed on the outer circumferential surface of the throttle distribution pipe 11 so that the heat exchange medium throttled through the orifice pipe 82 can be re-throttled and distributed to the evaporation zone. [76] The throttling means 80 having the above configuration is primarily throttled while the liquid heat exchange medium flowing from the condenser passes through the first throttling means 81 such as the orifice tube 82 and is installed in the evaporation region. Through the distribution hole 812 of the throttle distribution pipe 810, it is possible to distribute the re-throat and the heat exchange medium. At the same time, it will be possible to directly heat exchange with the outside air in the pair of plates 31. [77] 9 shows the throttling means 100 according to the fifth embodiment of the present invention. [78] Referring to the drawings, the throttling means 100 has a capillary throttle passage 113 capable of throttling a heat exchange medium on one side 112 based on the partition wall 111 formed at the center of the forming surface of the plate 110. To form. In addition, a plurality of dimples 115 may be formed on the other side 114 partitioned by the partition wall 111 to promote turbulence of the heat exchange medium. [79] That is, the heat exchanger has a flow passage of the heat exchange medium that is introduced after the first throttle on one side and re-exchanged and exchanges with the outside air at the same time, and the flow passage of the heat exchange medium that is heat-exchanged and discharged from the evaporation area on the other side. . [80] In the throttling means 100 having the above configuration, the heat-exchanging medium primarily throttled through the throttling means such as an orifice tube is re-throttled through the throttling passage 113 formed on one side 112 of the plate 110. At the same time, heat exchange with the outside air to evaporate the heat exchange medium. The heat exchange medium heat exchanged in the evaporation region may be discharged to the compressor while promoting turbulence while passing through the dimples 115 formed on the other side 114 of the plate 110. [81] In other embodiments, heat efficiency may be improved by heat exchange between the liquid heat exchange medium being throttled and the heat exchange medium that is discharged by heat exchange with the outside air to the evaporation zone. [82] That is, the heat exchanger has a throttleable portion formed at the inlet of the evaporation zone, and is separated into an evaporation zone which is not throttled behind the heat exchanger, the heat exchange medium being throttled at the inlet of the evaporation zone, and the heat exchange medium exchanged from the evaporation zone. Heat exchange is possible between. [83] The heat exchanger may be provided with a throttling means as described above at the front of the evaporation zone in which a plurality of plates in which a plurality of passages through which the heat exchange medium is flowable are stacked are installed, and the heat exchange medium may be supplied to the evaporation zone as indicated by the arrow. [84] The heat exchange medium condensed into the evaporation zone is preferably installed to maintain a counter flow in which the heat flow medium exchanges with the outside air through the evaporation zone and discharges the heat exchange medium. [85] The heat exchanger having the above structure has a liquid phase heat exchange medium throttled at a relatively low temperature inlet of the evaporation zone, and a heat exchange medium heat exchanged with outside air from the evaporation zone at a relatively higher temperature than the heat exchange medium throttled by the throttling means. At the inlet of the heat exchange. At this time, the inflow and outflow of the heat exchange medium maintains the flow direction opposite each other. [86] As described above, the throttling unit integrated evaporator of the present invention can obtain the following effects. [87] Since the evaporator is integrally installed with throttling means, it is possible to implement a cooling system that circulates the heat exchange medium in the order of the compressor, the condenser, and the evaporator without removing the expansion valve, thereby simplifying the structure and reducing the number of work processes. Manufacturing cost is reduced. In addition, since the heat exchange with the throttling and the outside air directly in the evaporation zone is made at the same time, the thermal efficiency is improved. [88] Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
