Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to an integrated heat exchanger and a thermal management system and a vehicle comprising the same. Background Art

[0002] With the global emphasis on environmental protection and sustainable development, electric vehicles (EVs), as a low-emission mode of transportation, are gradually becoming a mainstream choice in the automotive industry. The successful promotion of EVs is inseparable from efficient power systems and a comfortable riding experience, and the vehicle's cooling system plays a key role in this process.

[0003] Currently, most electric vehicles use a split cooling system, with separate designs for the in-vehicle cooling system (i.e., the traditional in-vehicle air conditioning system) and the battery cooling system to meet different temperature control requirements. Specifically, the in-vehicle cooling system uses the refrigerant's phase change process in the evaporator to transform the refrigerant from liquid to gas, absorbing heat from the air flowing through the evaporator, thereby lowering the temperature inside the vehicle. The battery cooling system, on the other hand, uses a separate chiller. Through a similar cooling process, the refrigerant's phase change absorbs heat from the coolant (which cools the battery), ensuring that the battery operates within a suitable temperature range.

[0004] However, while the split cooling system offers a certain degree of flexibility by independently controlling the cooling of the interior air and the battery, achieving independent temperature control of the interior air and the battery requires the integration of multiple independent components within the system. For example, two independent condensers, two evaporators, and two expansion valves are required for the system, respectively. This duplication of multiple components with similar functions increases not only the number of assembly steps and labor, but also installation and maintenance costs.

[0005] Therefore, how to overcome the above-mentioned shortcomings of the prior art has become a technical problem that all parties in the field are eager to solve. Utility Model Content

[0034] Reference will now be made in detail to various embodiments of the present invention, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with the exemplary embodiments, it should be understood that this description is not intended to limit the present invention to these exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.

[0035] To facilitate explanation and precise definition in the appended claims, the terms "upper," "lower," "left," "right," "front," and "rear" are used to describe features of the exemplary embodiments with reference to the positions of such features as shown in the drawings.

[0036] See first Figure 1 and Figure 2 The integrated heat exchanger 100 (hereinafter referred to as heat exchanger 100 ) includes a plurality of flow channel plates 110 , each of which has a plurality of refrigerant flow channels 111 and a plurality of coolant flow channels 112 . The refrigerant flow channels 111 are used to flow a refrigerant capable of absorbing heat from the surrounding environment, while the coolant flow channels 112 are used to flow a coolant used to cool the battery modules. The refrigerant in the refrigerant flow channels 111 absorbs heat from the coolant in the coolant flow channels 112 through evaporation, thereby lowering the temperature of the coolant.

[0037] Multiple refrigerant flow channels 111 and multiple coolant flow channels 112 are alternately arranged adjacent to each other. In other words, the refrigerant flow channels 111 and the coolant flow channels 112 provided on the flow channel plate 110 are adjacent to each other, and the adjacent refrigerant flow channels 111 and coolant flow channels 112 are closely adjacent to each other, thereby facilitating heat exchange between the refrigerant and coolant in the adjacent refrigerant flow channels 111 and coolant flow channels 112. By alternately and adjacently arranging the multiple refrigerant flow channels 111 and the multiple coolant flow channels 112 on the flow channel plate 110, the contact area between the refrigerant and the coolant in the heat exchanger 100 can be increased, thereby improving the efficiency of heat exchange between the refrigerant and the coolant.

[0038] The refrigerant flow channels 111 of the multiple flow channel plates 110 are connected to form a refrigerant channel. A refrigerant inlet 120 and a refrigerant outlet 130 are connected at each end of the refrigerant channel. Refrigerant enters the refrigerant channel from the refrigerant inlet 120 and, within the multiple refrigerant flow channels 111, exchanges heat with air flowing through the heat exchanger, thereby lowering the air's temperature. Simultaneously, refrigerant also exchanges heat with the coolant in the coolant flow channels 112, thereby lowering the coolant's temperature. Finally, the refrigerant, having undergone heat exchange, flows out of the refrigerant outlet 130.

[0039] The coolant channels 112 of the multiple flow channel plates 110 are interconnected to form a coolant channel. A coolant inlet 140 and a coolant outlet 150 are connected at each end of the coolant channel. Coolant enters the coolant channel from the coolant inlet 140 and exchanges heat with the refrigerant in the multiple coolant channels 112, thereby reducing its own temperature. Finally, the coolant, having undergone heat exchange, flows out of the coolant outlet 150.

[0040] See Figure 1 、 Figure 3 、 Figure 3a and Figure 3b The heat exchanger 100 is divided into a heat exchange area 100a and a heat exchange area 100b. A portion of the plurality of flow channel plates 110 is located in the heat exchange area 100a, and another portion of the plurality of flow channel plates 110 is located in the heat exchange area 100b.

[0041] See next Figure 1 、 Figure 3 、 Figure 3a 、 Figure 3b 、 Figure 4 、 Figure 5 The spatial structure of the heat exchanger 100 will be described in detail.

[0042] See Figure 1 The two heat exchange areas 100a and 100b are distributed along the front-to-back direction, and each flow channel plate 110 in the heat exchange areas 100a and 100b extends along the up-down direction. Figure 2 The refrigerant flow channels 111 and the coolant flow channels 112 of each flow channel plate 110 are alternately distributed along the front-to-back direction. Figure 3 、 Figure 3a 、 Figure 3b The flow channel plates 110 of the heat exchange areas 100a and 100b are spaced apart in the left-right direction, that is, there is a gap between two adjacent flow channel plates 110. The air flowing through the gap can exchange heat with the refrigerant in the refrigerant flow channel 111 of the flow channel plate 110, thereby reducing the temperature of the air.

[0043] Continue reading Figure 3 、 Figure 3a 、 Figure 3b The multiple flow channel plates in the heat exchanger 100 are divided into six groups, wherein the heat exchange area 100a includes the first group 110a, the second group 110b, and the third group 110c distributed from left to right, and the heat exchange area 100b includes the fourth group 110d, the fifth group 110e, and the sixth group 110f distributed from right to left.

[0044] As a result, the projections of the first group 110a and the sixth group 110f in the front-to-back direction overlap, the projections of the second group 110b and the fifth group 110e in the front-to-back direction overlap, and the projections of the third group 110c and the sixth group 110f in the front-to-back direction overlap. In other words, the first group 110a and the sixth group 110f are located on the left side of the heat exchanger 100, the third group 110c and the fourth group 110d are located on the right side of the heat exchanger 100, and the second group 110b and the fifth group 110e are both located in the middle of the heat exchanger 100 in the left-right direction.

[0045] It should be noted that Figure 3 This is only a schematic diagram of the corresponding relationship between the six sets of flow plates and the refrigerant manifold and the coolant manifold. Therefore, the spacing between two adjacent sets of flow plates in the figure does not actually exist in the heat exchanger. These spacings are only to make the positional relationship and connection relationship between the six sets of flow plates, the refrigerant manifold, and the coolant manifold clearer. In fact, the flow plates in the heat exchange area 100a and the heat exchange area 100b are arranged at equal intervals. Therefore, Figure 3 These intervals should not be considered as limitations of the present invention.

[0046] See Figure 3 and Figure 3a All of the refrigerant manifolds 161, 162, and 163 are located in the heat exchange area 100a. The refrigerant manifold 161 is located at the upper end of the first group 110a, a portion of the refrigerant manifold 162 is located at the lower end of the first group 110a, another portion of the refrigerant manifold 162 is located at the lower end of the second group 110b, a portion of the refrigerant manifold 163 is located at the upper end of the second group 110b, and another portion of the refrigerant manifold 163 is located at the upper end of the third group 110c.

[0047] That is, the refrigerant collecting chamber 161 and the refrigerant collecting chamber 163 are both located at the upper side of the heat exchange area 100 a , and the refrigerant collecting chamber 162 is located at the lower side of the heat exchange area 100 a .

[0048] Continue reading Figure 3 and Figure 3bRefrigerant manifolds 165, 166, and 167 are all located in heat exchange area 100b. A portion of refrigerant manifold 165 is located at the upper end of fourth group 110d, while another portion is located at the upper end of fifth group 110e. A portion of refrigerant manifold 166 is located at the lower end of fifth group 110e, while another portion is located at the lower end of sixth group 110f. Refrigerant manifold 167 is located at the upper end of sixth group 110f.

[0049] That is, the refrigerant collecting chamber 165 and the refrigerant collecting chamber 167 are both located at the upper side of the heat exchange area 100 b , and the refrigerant collecting chamber 166 is located at the lower side of the heat exchange area 100 b .

[0050] See Figures 3 and 4 Refrigerant manifold 164 connects (spans) heat exchange area 100a and heat exchange area 100b. In other words, a portion of refrigerant manifold 164 is located in heat exchange area 100a, while another portion of refrigerant manifold 164 is located in heat exchange area 100b. A portion of refrigerant manifold 164 is disposed at the lower end of third group 110c, while another portion of refrigerant manifold 164 is disposed at the lower end of fourth group 110d.

[0051] That is, a portion of the refrigerant collecting chamber 164 is located at a lower side of the heat exchange area 100 a , and another portion of the refrigerant collecting chamber 164 is located at a lower side of the heat exchange area 100 b .

[0052] Continue reading Figure 3 and Figure 3a All of the cooling liquid manifolds 171, 172, and 173 are located in the heat exchange area 100a. Cooling liquid manifold 171 is located at the lower end of the third group 110c, a portion of cooling liquid manifold 172 is located at the upper end of the third group 110c, another portion of cooling liquid manifold 172 is located at the upper end of the second group 110b, a portion of cooling liquid manifold 173 is located at the lower end of the second group 110b, and another portion of cooling liquid manifold 173 is located at the lower end of the first group 110a.

[0053] That is, the cooling liquid manifold 171 and the cooling liquid manifold 173 are both located at the lower side of the heat exchange area 100 a , and the cooling liquid manifold 172 is located at the upper side of the heat exchange area 100 a .

[0054] Continue reading Figure 3 and Figure 3bCooling liquid manifolds 175, 176, and 177 are all located in heat exchange area 100b. A portion of cooling liquid manifold 175 is located at the lower end of sixth group 110f, while another portion is located at the lower end of fifth group 110e. A portion of cooling liquid manifold 176 is located at the upper end of fifth group 110e, while another portion is located at the upper end of fourth group 110d. Cooling liquid manifold 177 is located at the lower end of fourth group 110d.

[0055] That is, the cooling liquid manifold 175 and the cooling liquid manifold 177 are both located at the lower side of the heat exchange area 100 b , and the cooling liquid manifold 176 is located at the upper side of the heat exchange area 100 b .

[0056] See Figure 3 、 Figure 3a 、 Figure 3b and Figure 5 Coolant manifold 174 connects (spans) heat exchange area 100a and heat exchange area 100b. In other words, a portion of coolant manifold 174 is located in heat exchange area 100a, while another portion of coolant manifold 174 is located in heat exchange area 100b. A portion of coolant manifold 174 is disposed at the upper end of first group 110a, while another portion of coolant manifold 174 is disposed at the upper end of sixth group 110f.

[0057] That is, a portion of the coolant manifold 174 is located on the upper side of the heat exchange area 100 a , and another portion of the coolant manifold 174 is located on the upper side of the heat exchange area 100 b .

[0058] It should be noted that Figure 4 The gap between the middle heat exchange area 100a and the heat exchange area 100b is only to more clearly distinguish the positional relationship between the refrigerant collecting chambers 163 and 165, between the coolant collecting chambers 172 and 176, between the coolant collecting chambers 171 and 177, and between the third group 100 and the fourth group 100d. These gaps do not necessarily exist in reality and should not be regarded as limitations on the present invention.

[0059] Likewise, Figure 5 The gap between the middle heat exchange area 100a and the heat exchange area 100b is only for more clearly distinguishing the positional relationship between the refrigerant collecting chambers 161 and 167, between the refrigerant collecting chambers 162 and 166, between the coolant collecting chambers 173 and 175, and between the first group 100a and the sixth group 100f. These gaps do not necessarily exist in reality and should not be regarded as limitations on the present invention.

[0060] In fact, if Figure 2aAs shown, the flow channel plates 110 of the heat exchange area 100a and the heat exchange area 100b can be integrally formed. Specifically, the flow channel plates 110 of the heat exchange area 100a and the heat exchange area 100b correspond one to one in the front-to-back direction, that is, the projection of each flow channel plate 110 in the heat exchange area 100a in the front-to-back direction can overlap with the projection of one flow channel plate 110 in the heat exchange area 100b in the front-to-back direction, and the two flow channel plates 110 can also be integrally formed, that is, the two corresponding flow channel plates 110 along the front-to-back direction can be an integrally formed plate body, the front portion of the plate body is located in the heat exchange area 100b, serving as the flow channel plate 110 constituting the heat exchange area 100b, and the rear portion of the plate body is located in the heat exchange area 100a, serving as the flow channel plate 110 constituting the heat exchange area 100a.

[0061] See Figure 1 、 Figures 3 to 5 The refrigerant manifolds 161, 162, 163, 164, 165, 166, and 167 and the coolant manifolds 171, 172, 173, 174, 175, 176, and 177 are stacked on both sides of the heat exchanger 100 in the vertical direction, corresponding to each other. In other words, the refrigerant manifolds and coolant manifolds provided at the ends of each of the first, second, third, fourth, fifth, and sixth groups 110a, 110b, 110d, 110e, and 110f in the vertical direction are stacked in the vertical direction. Thus, each flow channel plate 110 is provided with a refrigerant manifold and a coolant manifold stacked in the vertical direction at both ends in the vertical direction.

[0062] See below Figures 3 to 5 , the corresponding relationship between the refrigerant collecting chambers 161, 162, 163, 164, 165, 166, 167 and the coolant collecting chambers 171, 172, 173, 174, 175, 176, 177 is described in detail.

[0069] See Figure 2The refrigerant flow channel 111 and the coolant flow channel 112 in the flow channel plate 110 respectively form openings 111a and 112a along the upper and lower ends of the flow channel plate 110. The refrigerant manifolds 161, 163, 165, and 167 can connect to the refrigerant flow channel 111 at the upper end of the flow channel plate 110 through the opening 111a, and the coolant manifolds 172, 174, and 176 can connect to the coolant flow channel at the upper end of the flow channel plate 110 through the opening 112a. At the same time, the refrigerant manifolds 162, 164, and 166 can connect to the refrigerant flow channel at the lower end of the flow channel plate through the opening 111a, and the coolant manifolds 171, 173, 175, and 177 can connect to the coolant flow channel at the lower end of the flow channel plate through the opening 112a. Specifically, the opening 111a of the refrigerant flow channel 111 and the opening 112a of the coolant flow channel 112 have a distance in the up and down directions, so that the refrigerant flow channel 111 is connected to the refrigerant collecting chambers 161, 162, 163, 164, 165, 166, and 167 through the opening 111a, and the coolant flow channel 112 is connected to the coolant collecting chambers 171, 172, 173, 174, 175, 176, and 177 through the opening 112a.

[0070] See below for details Figure 2 6 , through the stacked refrigerant collecting chamber 161 and the coolant collecting chamber 174 , it is exemplified how the refrigerant flow channel 111 of the flow channel plate 110 is connected to the refrigerant collecting chambers 161, 162, 163, 164, 165, 166, and 167, and how the coolant flow channel 112 of the flow channel plate 110 is connected to the coolant collecting chambers 171, 172, 173, 174, 175, 176, and 177 when the refrigerant collecting chamber and the coolant collecting chamber are stacked.

[0071] See Figure 1 6 , the upper ends of the flow channel plates 110 of the first group 110a extend vertically through the coolant manifold 174 to the refrigerant manifold 161. Openings 111a are formed on the top surfaces at locations corresponding to the refrigerant flow channels 111, and openings 112a are formed in the coolant manifold at locations corresponding to the coolant flow channels 112. Openings 112a extend horizontally through the flow channel plates 110. Thus, the refrigerant flow channels 111 of the flow channel plates 110 of the first group 110a can communicate with the refrigerant manifold 161 through openings 111a, and the coolant flow channels 112 of the flow channel plates 110 of the first group 110a can communicate with the coolant manifold 174 through openings 112a.

[0072] In other words, the coolant flow channel 112 of the flow channel plate 110 extends vertically to the coolant manifold 174, then terminates in the coolant manifold 174 and defines an opening 112a. The refrigerant flow channel 111 of the flow channel plate 110 extends vertically upward through the coolant manifold 174, then continues toward the refrigerant manifold 161, forming an opening 111a that connects to the refrigerant manifold 161. That is, the refrigerant flow channel 111 and the coolant flow channel 112 extend vertically upward to different lengths, such that the refrigerant flow channel 111 connects to the refrigerant manifold 161, while the coolant flow channel 112 connects to the coolant manifold 174, which is stacked vertically with the refrigerant manifold 161.

[0073] As described above, the present invention illustrates how the openings 111a and 112a are formed at the upper end of the flow channel plate 110 through the refrigerant collecting chamber 161 and the coolant collecting chamber 174, so that the refrigerant flow channel 111 and the coolant flow channel 112 in the flow channel plate 110 are respectively connected to the refrigerant collecting chamber and the coolant collecting chamber stacked on top of each other.

[0074] See Figure 2 , the openings 111a and 112a formed at the lower end of the flow channel plate 110 are different from those at its upper end. The opening 111a at the lower end of the flow channel plate 110 is formed on the left and right side surfaces, that is, each refrigerant flow channel 111 has two openings 111a at the lower end, and the projections of the two openings 111a in the left and right directions coincide, so that the refrigerant in the refrigerant collecting chamber provided at the lower end of the corresponding flow channel plate 110 can pass through the flow channel plate 110 and flow in the left and right directions within the refrigerant collecting chamber. The opening 112a at the lower end of the flow channel plate 110 forms the bottom surface, that is, each coolant flow channel 112 has an opening 112a at the lower end, so that the lower end of the coolant flow channel 112 can be connected to the coolant collecting chamber below the refrigerant collecting chamber.

[0078] All of the flow channel plates 110 in the fourth group 110d can form openings 111a and 112a at their lower ends, allowing all of the refrigerant flow channels 111 in the fourth group 110d to communicate with the refrigerant manifold 164, while all of the coolant flow channels 112 in the fourth group 110d can communicate with the coolant manifold 177. Furthermore, all of the flow channel plates 110 in the fourth group 110d can form openings 111a and 112a at their upper ends, allowing all of the refrigerant flow channels 111 in the fourth group 110d to communicate with the refrigerant manifold 165, while all of the coolant flow channels 112 in the third group 110c can communicate with the coolant manifold 176.

[0079] All of the flow channel plates 110 in the fifth group 110e can form openings 111a and 112a at their upper ends, allowing all of the refrigerant flow channels 111 in the fifth group 110e to communicate with the refrigerant manifold 165, while all of the coolant flow channels 112 in the fifth group 110e can communicate with the coolant manifold 176.

[0081] The following, in conjunction with the accompanying drawings, describes in detail the upstream and downstream relationships of the refrigerant flow channels 111, the coolant flow channels 112 and the refrigerant collecting chambers 161, 162, 163, 164, 165, 166, 167 and the coolant collecting chambers 171, 172, 173, 174, 175, 176, 177 in the six groups of flow channel plates 110 through the flow process of the refrigerant and the coolant in the heat exchange area.

[0082] See below for more information. Figure 1 、 Figure 3 、 Figure 3a 、 Figure 3b and Figure 4 , introducing the upstream and downstream relationship between the refrigerant collecting chambers 161, 162, 163, 164, 165, 166, 167 and the refrigerant flow channels 111 in the six groups of flow channel plates.

[0083] The refrigerant collecting chamber 161 is connected between the refrigerant inlet 120 and the refrigerant flow channels 111 of the first group 110a, so that the refrigerant can enter the refrigerant collecting chamber 161 from the refrigerant inlet 120 and then be distributed to each refrigerant flow channel 111 of the first group 110a through the refrigerant collecting chamber 161.

[0084] The refrigerant collecting chamber 162 is connected between the refrigerant flow channels 111 of the first group 110a and the refrigerant flow channels 111 of the second group 110b. The refrigerant in all the refrigerant flow channels 111 of the first group 110a can converge into the refrigerant collecting chamber 162, and then be diverted to each refrigerant flow channel 111 of the second group 110b through the refrigerant collecting chamber 162.

[0085] The refrigerant collecting chamber 163 is connected between the refrigerant flow channels 111 of the second group 110b and the refrigerant flow channels 111 of the third group 110c, so that the refrigerants in all the refrigerant flow channels 111 of the second group 110b can converge into the refrigerant collecting chamber 163, and then be diverted to each refrigerant flow channel 111 of the third group 110c through the refrigerant collecting chamber 163.

[0086] The refrigerant collecting chamber 164 is connected between the refrigerant flow channels 111 of the third group 110c and the refrigerant flow channels 111 of the fourth group 110d, so that the refrigerants in all the refrigerant flow channels 111 of the third group 110c can converge into the refrigerant collecting chamber 164, and then be diverted to each refrigerant flow channel 111 of the fourth group 110d through the refrigerant collecting chamber 164.

[0087] The refrigerant collecting chamber 165 is connected between the refrigerant flow channels 111 of the fourth group 110d and the refrigerant flow channels 111 of the fifth group 110e, so that the refrigerants in all the refrigerant flow channels 111 of the fourth group 110d can converge into the refrigerant collecting chamber 165, and then be diverted to each refrigerant flow channel 111 of the fifth group 110e through the refrigerant collecting chamber 165.

[0088] The refrigerant collecting chamber 166 is connected between the refrigerant flow channels 111 of the fifth group 110e and the refrigerant flow channels 111 of the sixth group 110f. Thus, the refrigerants in all the refrigerant flow channels 111 of the fifth group 110e can converge into the refrigerant collecting chamber 166, and then be diverted to each refrigerant flow channel 111 of the sixth group 110f through the refrigerant collecting chamber 166.

[0089] The refrigerant collecting chamber 167 is connected between the refrigerant flow channels 111 of the sixth group 110f and the refrigerant outlet 130 , so that the refrigerants in all the refrigerant flow channels 111 of the sixth group 110f can converge into the refrigerant collecting chamber 167 and then flow out from the refrigerant outlet 130 through the refrigerant collecting chamber 167 .

[0090] See below Figure 3 and Figure 5 The upstream and downstream relationships between the coolant manifolds 171 , 172 , 173 , 174 , 175 , 176 , and 177 and the coolant channels 112 within the six channels plates 110 are described.

[0091] The coolant manifold 171 is connected between the coolant inlet 140 and the coolant flow channels 112 of the third group 110 c , so that the coolant can enter the coolant manifold 171 from the coolant inlet 140 and then be diverted to each coolant flow channel 112 of the third group 110 c through the coolant manifold 171 .

[0092] The coolant manifold 172 is connected between the coolant channels 112 of the third group 110 c and the coolant channels 112 of the second group 110 b , so that the coolant in all the coolant channels 112 of the third group 110 c can converge into the coolant manifold 172 , and then be diverted to each coolant channel 112 of the second group 110 b through the coolant manifold 172 .

[0093] The coolant collecting chamber 173 is connected between the coolant flow channels 112 of the second group 110b and the coolant flow channels 112 of the first group 110a, so that the coolant in all the coolant flow channels 112 of the second group 110b can converge into the coolant collecting chamber 173, and then be diverted to each coolant flow channel 112 of the first group 110a through the coolant collecting chamber 173.

[0094] The coolant collecting chamber 174 is connected between the coolant flow channels 112 of the first group 110a and the coolant flow channels 112 of the sixth group 110f. Thus, the coolant in all the coolant flow channels 112 of the first group 110a can converge into the coolant collecting chamber 174, and then be diverted to each coolant flow channel 112 of the sixth group 110f through the coolant collecting chamber 174.

[0095] The coolant collecting chamber 175 is connected between the coolant flow channels 112 of the sixth group 110f and the coolant flow channels 112 of the fifth group 110e. Thus, the coolant in all the coolant flow channels 112 of the sixth group 110f can converge into the coolant collecting chamber 175, and then be diverted to each coolant flow channel 112 of the fifth group 110e through the coolant collecting chamber 175.

[0096] The coolant collecting chamber 176 is connected between the coolant flow channels 112 of the fifth group 110e and the coolant flow channels 112 of the fourth group 110d. Thus, the coolant in all the coolant flow channels 112 of the fifth group 110e can converge into the coolant collecting chamber 176, and then be diverted to each coolant flow channel 112 of the fourth group 110d through the coolant collecting chamber 176.

[0097] The coolant collecting chamber 177 is connected between the coolant flow channels 112 of the fourth group 110d and the coolant outlet 150, so that the coolant in all the coolant flow channels 112 of the fourth group 110d can converge into the coolant collecting chamber 177, and then flow out from the coolant outlet 150 through the coolant collecting chamber 177.

[0098] From the above, it can be seen that the refrigerant and the coolant can flow in opposite directions in the heat exchanger 100, that is, the flow directions of the two are opposite in the heat exchange area 100a, and the flow directions of the two are also opposite in the heat exchange area 100b.

[0099] Heat exchanger 100 further includes heat dissipation fins 180 disposed between a plurality of spaced-apart flow plates 110. When air passes through the gaps between flow plates 110, it comes into contact with heat dissipation fins 180, thereby improving the heat exchange efficiency between the air and the refrigerant within flow plates 110.

[0100] Specifically, there are multiple heat dissipation fins 180, and the multiple heat dissipation fins 180 are respectively arranged between two adjacent flow channel plates 110, and the heat dissipation fins 180 are connected to the flow channel plates 110, that is, the heat dissipation fins 180 between two adjacent flow channel plates 110 will be connected to the two flow channel plates 110 respectively.

[0101] In summary, the integrated heat exchanger 100 provided by the present invention integrates the chiller in a conventional cooling device 220 with the evaporator in a conventional refrigeration device 210, enabling the integrated heat exchanger 100 to be used in both the refrigeration device 210 and the cooling device 220. The cooling liquid in the cooling device 220 can be cooled by the operation of the refrigeration device 210. This further enhances the level of product integration, thereby contributing to product simplification and cost reduction.

[0102] Figure 7 It is a structural schematic diagram of the heat exchange system provided by the utility model.

[0103] See Figure 7 The present invention further provides a thermal management system 200. The thermal management system 200 includes a refrigeration device 210, a cooling device 220, and the heat exchanger 100 described above.

[0104] Refrigeration device 210 includes a refrigerant line 211, and a compressor 212, a condenser 213, and an expansion valve 214 connected via refrigerant line 211. Heat exchanger 100 is connected to refrigerant line 211 via a refrigerant inlet 120 and a refrigerant outlet 130. Heat exchanger 100 is located on refrigerant line 211 between expansion valve 214 and compressor 212. The refrigerant inlet of heat exchanger 100 is located on the side of refrigerant line 211 near expansion valve 214, while the refrigerant outlet 130 of heat exchanger 100 is located on the side of refrigerant line 211 near compressor 212. Thus, refrigerant throttled by expansion valve 214 is delivered to refrigerant inlet 120 of heat exchanger 100. After heat exchange within heat exchanger 100, the refrigerant is delivered to compressor 212 via refrigerant outlet 130 of heat exchanger 100.

[0105] When the refrigeration device 210 is working, the compressor 212 compresses the refrigerant into a high-temperature, high-pressure gas, which is then transported to the condenser 213 and exchanges heat with the outside world in the condenser 213. The high-temperature, high-pressure gas is then gradually cooled into a high-pressure liquid, which is then transported to the expansion valve 214. After throttling by the expansion valve 214, the high-temperature, high-pressure liquid becomes a low-temperature, low-pressure gas-liquid mixture, which is then evaporated into a low-temperature, low-pressure gas through heat absorption in the heat exchanger 100. The low-temperature, low-pressure gas is then sucked into the compressor 212 again to start the next cycle.

[0106] The cooling device 220 includes a coolant line 221 , and a pump 222 , a battery module 223 , a heating module 224 , and a liquid storage tank 225 connected via the coolant line 221 , wherein the heating module 224 is disposed on the coolant line 221 between the pump 222 and the battery module 223 .

[0107] The heat exchanger 100 is connected to the coolant pipeline 221 through the coolant inlet 140 and the coolant outlet 150, and the heat exchanger 100 is arranged on the coolant pipeline 221 between the pump 222 and the heating module 224. The coolant inlet 140 of the heat exchanger 100 is located on the side of the coolant pipeline 221 close to the pump 222, and the coolant outlet 150 of the heat exchanger 100 is located on the side of the coolant pipeline 221 close to the heating module.

[0108] The thermal management system 200 further includes a bypass line 226 , a first end of which is connected to the coolant line 221 between the heat exchanger 100 and the pump 222 , and a second end of which is connected to the coolant line 221 between the heat exchanger 100 and the heating module 224 .

[0109] A three-way valve 230 is also provided on the coolant pipeline 221 between the pump 222 and the heat exchanger 100, and the first end of the bypass pipeline 226 is connected to the three-way valve 230, thereby connecting the first end of the bypass pipeline 226 to the coolant pipeline between the heat exchanger 100 and the pump 222.

[0110] The three-way valve 230 selectively shuts off the portion of the coolant line 221 where the heat exchanger 100 is located and connects the bypass line 226, allowing the coolant to circulate through a complete closed loop formed by the remaining portion of the coolant line 221 and the bypass line 226. At this point, with the operation of the pump 222, the coolant can circulate within the remaining portion of the coolant line 221 (the heating module 224, the battery module 223, the liquid storage tank 225, and the coolant line 221 where the pump 222 is located) and the bypass line 226, sequentially passing through the heating module 224, the battery module 223, and the liquid storage tank 225 during the circulation process.

[0111] The three-way valve 230 can also selectively close the bypass line 226, allowing the coolant to circulate in a complete closed loop along the coolant line 221. In other words, the coolant can circulate along the entire coolant line 221 and can flow through the heat exchanger 100, the heating module 224, the battery module 223, and the liquid storage tank 225 in sequence during the circulation process.

[0112] When heating the battery module 223 is required, the three-way valve 230 is operated to shut off the portion of the coolant line 221 where the heat exchanger 100 is located, thereby forming a complete closed loop between the bypass line 226 and the remaining portion of the coolant line (i.e., the coolant line 221 where the pump 222, heating module 224, battery module 223, and liquid storage tank 225 are located). The pump 222 controls the coolant to flow sequentially through the heating module 224 and then the battery module 223. The coolant flowing through the heating module 224 increases in temperature, and then heats the battery module 223 after flowing to the battery module 223.

[0113] When the battery module 223 needs to be cooled, the heating module 224 is turned off, the refrigeration device 210 is turned on, and the three-way valve is operated so that the coolant pipeline 221 can form a complete closed loop. The pump 222 controls the coolant to flow through the heat exchanger 100 and the battery module 223 in sequence. The coolant heat exchanger 100 neutralizes the refrigerant to exchange heat and release heat, thereby lowering its own temperature, and then flows to the battery module 223 to cool the battery.

[0114] In particular, when cooling the battery module 223, the refrigerant and the coolant can flow in opposite directions in the heat exchanger 100, that is, the flow directions of the two are opposite in the heat exchange area 100a, and the flow directions of the two are opposite in the heat exchange area 100b.

[0115] According to the heat exchange system provided by the present invention, the structure of the heat exchange system is simplified by adopting an integrated heat exchanger 100 that integrates the chiller (Chiller) in the traditional cooling device 220 and the evaporator (Evaporator) in the traditional refrigeration pipeline, thereby reducing the space occupied by the heat exchanger 100 and reducing the cost and installation steps of the heat exchanger 100.

[0116] Finally, the present invention also provides a vehicle, which adopts the heat exchanger 100 or heat exchange system described above in the present invention. The specific connection method of the heat exchanger 100 in the vehicle has been introduced in the heat exchanger 100 system, and the setting of the heat exchange system in the vehicle is a technology that can be known to those skilled in the art and will not be repeated in this article.

[0117] According to the vehicle provided by the present invention, by using the integrated heat exchanger 100 in the vehicle's heat exchange system, the vehicle's refrigeration device 210 can cool the coolant, thereby eliminating the need for a chiller, an expansion valve 214, and the portion of the cooling line connecting the chiller and the expansion valve 214 in the cooling system. The vehicle provided by the present invention not only reduces the number of vehicle components and assembly steps, thereby improving production efficiency, but also reduces installation and maintenance costs to a certain extent.
