Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thermal management, in particular to a thermal management integrated module, a thermal management system and an electric vehicle. BACKGROUND

[0002] In recent years, environmental pollution and energy shortage have accelerated the development and utilization of green renewable energy. Electric vehicles have become a research hotspot in the automotive industry due to their low pollution, low noise, high energy efficiency and other advantages. Electric vehicles include a thermal management system, which can generally be used to achieve the functions of cooling / heating the passenger compartment of the electric vehicle, heat dissipation of the battery and power system, and waste heat recovery. The thermal management system includes components such as a compressor, a condenser, a cooler, a valve body, and a water pump. Different components are connected by pipelines. In one prior art, the condenser and the cooler use a plate heat exchanger, which includes a plurality of metal sheets arranged at intervals and welded to form non-communicating refrigerant flow channels and cooling liquid flow channels. The refrigerant and the cooling liquid flow through the corresponding flow channels in a countercurrent manner and exchange heat. Since the plate heat exchanger contains a large number of metal sheets, and any two adjacent metal sheets need to be welded, the structure of the plate heat exchanger is complex, and the production cost is high, thereby increasing the production cost and maintenance cost of the thermal management system accordingly. SUMMARY

[0003] The present application provides a thermal management integrated module, a thermal management system and an electric vehicle, which are used to simplify the structure of the condenser or the cooler, reduce the production cost of the condenser or the cooler, thereby reducing the production cost of the thermal management system and the electric vehicle accordingly, and further improving the competitiveness of the electric vehicle.

[0004] In a first aspect, the present application provides a thermal management integrated module. Specifically, the thermal management integrated module includes a first heat exchange assembly and a flow channel plate. The first heat exchange assembly includes a box body and a heat exchange pipeline located in the box body. The box body is used to contain a cooling liquid, and at least part of the heat exchange pipeline is located in the cooling liquid. The heat exchange pipeline has a first refrigerant inlet and a first refrigerant outlet, which are respectively used to communicate with a refrigerant transmission pipeline. In use, the refrigerant transmission pipeline connected with the first refrigerant inlet is connected with the outlet of the compressor, and the refrigerant transmission pipeline connected with the first refrigerant outlet is connected with the inlet of the compressor. The above refrigerant transmission pipeline can transmit refrigerant between the heat exchange pipeline and the compressor. The refrigerant exchanges heat with the cooling liquid in the box body through the wall of the heat exchange pipeline during the flow through the heat exchange pipeline, so that the temperature of the cooling liquid is reduced or increased.

[0005] The housing and the manifold plate are connected, and the housing has a coolant inlet and a coolant outlet, while the manifold plate has a first manifold opening and a second manifold opening. The coolant inlet and the first manifold opening are in communication, while the coolant outlet and the second manifold opening are in communication, allowing the coolant to flow from the manifold plate to the housing, or vice versa.

[0006] In the above-mentioned thermal management integrated module, the heat exchange pipeline is immersed in the coolant so that the refrigerant can exchange heat with the coolant in the process of flowing through the heat exchange pipeline. The plate exchange form of stacked welding is not used, which simplifies the structure of the first heat exchange component and reduces the production cost of the first heat exchange component, thereby correspondingly reducing the production cost of the thermal management system and electric vehicles, thereby helping to enhance the competitiveness of electric vehicles. In addition, since the first heat exchange component has fewer parts, the repair and maintenance of the first heat exchange component is more convenient. For example, during use, the box and the heat exchange pipeline can be repaired or replaced separately to extend the service life of the first heat exchange component and reduce the cost of use. During use, the above-mentioned first heat exchange component can also reduce the maintenance cost of the thermal management system and electric vehicles accordingly, thereby helping to enhance the competitiveness of electric vehicles.

[0007] When specifically arranging the heat exchange pipeline, the heat exchange pipeline includes various structural forms. In one structural form, the heat exchange pipeline includes a first header, a second header, and multiple branch pipes. The first refrigerant inlet of the heat exchange pipeline is located in the first header, and the first refrigerant outlet of the heat exchange pipeline is located in the second header. When specifically arranging the above pipeline, the first header and the second header are arranged side by side; the multiple branch pipes are located between the first header and the second header and arranged at intervals, and each branch pipe connects the first header and the second header. As the refrigerant flows through the above heat exchange pipeline, the refrigerant first enters the first header. After flowing out of the first header, the refrigerant forms multiple branches and enters the corresponding branch pipes. As the refrigerant flows through the branch pipes, heat is exchanged between the branch pipe walls and the coolant outside the branch pipes. The refrigerant in each branch pipe enters the second header, converges, and flows out. In another structural form, the heat exchange pipeline can also be a serpentine pipeline. The serpentine pipeline can increase the length of the pipeline within a certain space by bending back and forth, extending the flow path of the refrigerant, thereby improving the heat exchange effect between the refrigerant and the coolant.

[0008] When configuring the branch pipes, reducing their flow area allows them to form microchannels, thereby reducing the refrigerant flow rate within the branch pipes. This allows the smaller amount of refrigerant liquid to more fully exchange heat with the coolant as it flows through the branch pipes, thereby improving the heat exchange efficiency between the refrigerant and coolant. In one optional technical solution, the branch pipes are flat. The branch pipes include a first sidewall and a second sidewall disposed opposite each other, with a small gap between the first and second sidewalls, thereby forming microchannels.

[0009] To improve the heat exchange efficiency between the refrigerant and the coolant, an optional technical solution is to have fins on the surface of the branch pipe. The fins can increase the surface area of ​​the branch pipe, thereby increasing the heat exchange area between the branch pipe and the coolant, thereby improving the heat exchange efficiency between the refrigerant and the coolant.

[0010] In the thermal management integrated module, the housing and the flow channel plate of the first heat exchange component can be arranged adjacent to each other and connected. In a specific implementation, in an optional technical solution, the housing includes a bottom plate, which is located on the side of the heat exchange pipeline close to the flow channel plate, and the bottom plate and the flow channel plate are arranged adjacent to each other and connected. Specifically, the bottom plate can be welded to the flow channel plate, or connected to the flow channel plate by fasteners. Optionally, the fasteners are screws, bolts or rivets. In addition to the bottom plate, the above-mentioned housing can also include a cover plate and a side plate, wherein the cover plate is located on the side of the heat exchange pipeline away from the flow channel plate; the side plate is arranged around the heat exchange pipeline and is connected to the bottom plate and the cover plate. In another optional technical solution, the flow channel plate can be reused as the bottom plate of the housing. That is, the flow channel plate, the side plates of the housing and the cover plate form a cooling liquid storage chamber. Accordingly, the first flow channel port is reused as the cooling liquid inlet, and the second flow channel port is reused as the cooling liquid outlet. In the above technical solution, by reusing the flow channel plate as the bottom plate of the box, the number of components is reduced and the volume of the thermal management integrated module is reduced, thereby further optimizing the interior space and performance of the electric vehicle.

[0011] On the basis of the above-mentioned reuse of the flow channel plate as the bottom plate of the box, there are multiple connection methods when specifically connecting the flow channel plate and the side plate of the box. In one connection method, the flow channel plate includes a first substrate, the first substrate is arranged toward the heat exchange pipeline, and the first flow channel opening and the second flow channel opening are located on the first substrate. The first substrate and the side plate are an integral structure. In specific implementation, the first substrate and the side plate can be integrally formed through an injection molding process, which is beneficial to improving the structural strength and sealing of the box. In another connection method, the flow channel plate and the side plate can be connected by glue or fasteners. Optionally, the fasteners are screws, bolts or rivets.

[0012] When assembling the heat exchange pipeline in the box, the heat exchange pipeline can be fixed to the wall panel of the box, thereby improving the stability of the heat exchange pipeline. In an optional technical solution, the box includes a load-bearing plate, which is used to connect to the frame, and the heat exchange pipeline is fixed to the load-bearing plate. Optionally, the load-bearing plate can be the cover plate of the box or the side plate of the box. When the load-bearing plate is specifically set, the load-bearing plate can be a metal plate or a plastic plate with greater structural strength. After the load-bearing plate is fixed to the frame, it can serve to support components such as the heat exchange pipeline and the flow channel plate.

[0013] In one technical solution, the heat management integrated module includes two first heat exchange assemblies, which are arranged in series between the inlet and outlet of the compressor, and the first heat exchange assembly close to the outlet of the compressor can serve as a condenser, and the first heat exchange assembly away from the outlet of the compressor can serve as a cooler. For the convenience of description, the heat exchange pipelines in the above two first heat exchange assemblies are respectively referred to as a first heat exchange pipeline and a second heat exchange pipeline, and the boxes in the above two first heat exchange assemblies are respectively referred to as a first box and a second box, wherein the first heat exchange pipeline is located in the first box, and the second heat exchange pipeline is located in the second box. When specifically connected, the first refrigerant outlet of the first heat exchange pipeline and the first refrigerant inlet of the second heat exchange pipeline are communicated, the first refrigerant inlet of the first heat exchange pipeline is used to communicate with one refrigerant transmission pipeline, and the refrigerant transmission pipeline can be communicated with the outlet of the compressor. The first refrigerant outlet of the second heat exchange pipeline is used to communicate with another refrigerant transmission pipeline, and the refrigerant transmission pipeline can be communicated with the inlet of the compressor.

[0014] The above two first heat exchange assemblies include various combination structures. In one combination structure, the first box includes a first cover plate, which is located on the side of the first heat exchange pipeline away from the flow channel plate. The second box includes a second cover plate, which is located on the side of the second heat exchange pipeline away from the flow channel plate, and the second cover plate and the first cover plate are independent structures.

[0015] In another combination structure, the first box also includes the above first cover plate, the second box also includes the above second cover plate, and the first cover plate and the second cover plate are integrated structures. That is, the first box and the second box share the same cover plate.

[0016] In another combination structure, the first box and the second box include a shared partition plate, which is located between the first heat exchange pipeline and the second heat exchange pipeline. The partition plate plays a role in separating the cooling liquid, so that the cooling liquid in the first box and the cooling liquid in the second box do not mix. In one specific technical solution, the first box includes a first side plate, which is connected to the above partition plate and surrounds the periphery of the first heat exchange pipeline; the second box includes a second side plate, which is connected to the above partition plate and surrounds the periphery of the second heat exchange pipeline. When specifically arranging the first side plate and the second side plate, the first side plate and the second side plate can be integrated structures, so as to increase the structural strength of the box and improve the sealing effect of the box.

[0017] In one technical solution, the thermal management integrated module also includes an expansion valve, which is fixed to the first box and the second box, and the expansion valve is connected to the first heat exchange pipeline and the second heat exchange pipeline. The expansion valve can adjust the flow of refrigerant from the first heat exchange pipeline into the second heat exchange pipeline. When installing the expansion valve, in an optional technical solution, the first box has a first interface, which is connected to the first refrigerant outlet of the first heat exchange pipeline; the second box has a second interface, which is connected to the first refrigerant inlet of the second heat exchange pipeline; the expansion valve has a first valve port and a second valve port, wherein the first valve port covers the first interface and is connected to the first interface, and the second valve port covers the second interface and is connected to the second interface. After the expansion valve is installed according to the above solution, the expansion valve can be connected to the first heat exchange pipeline and the second heat exchange pipeline, and there is no need to set a refrigerant transmission pipeline between the expansion valve and the first heat exchange pipeline and the second heat exchange pipeline, thereby simplifying the structure of the thermal management integrated module and reducing the risk of refrigerant leakage during transmission.

[0018] In one technical solution, the thermal management integrated module also includes a liquid storage tank, which is located in the first box body. The liquid storage tank has a second refrigerant inlet and a second refrigerant outlet, the second refrigerant inlet is connected to the first refrigerant outlet of the first heat exchange pipeline, and the second refrigerant outlet is connected to the first refrigerant inlet of the second heat exchange pipeline. The liquid storage tank can store the refrigerant flowing out of the first heat exchange pipeline, and is conducive to separating the liquid refrigerant and the gaseous refrigerant, so that the liquid refrigerant enters the second heat exchange pipeline. In addition, by arranging the liquid storage tank in the first box body, the communication path between the liquid storage tank and the first heat exchange pipeline can be shortened, the structure of the thermal management integrated module can be simplified, and the overall space occupied can be reduced.

[0019] In the second aspect, the present application also provides a thermal management system. The thermal management system includes a compressor, a second heat exchange component and the thermal management integrated module described in any one of the first aspects above. In the above-mentioned thermal management integrated module, the first refrigerant inlet and the first refrigerant outlet of the heat exchange pipeline are respectively connected to the compressor through the refrigerant transmission pipeline. The flow channel plate also has a third flow channel opening and a fourth flow channel opening, and the third flow channel opening and the fourth flow channel opening are respectively connected to the second heat exchange component through the coolant transmission pipeline. By immersing the heat exchange pipeline in the coolant, the refrigerant can exchange heat with the coolant in the process of flowing through the heat exchange pipeline, and does not use the plate exchange form of stacking welding, which simplifies the structure of the first heat exchange component, reduces the production cost and maintenance cost of the first heat exchange component, and thus correspondingly reduces the production cost and maintenance cost of the thermal management system and electric vehicles, which is conducive to improving the competitiveness of electric vehicles.

[0020] In a third aspect, the present application also provides an electric vehicle. The electric vehicle comprises a vehicle frame and the thermal management system described in the second aspect, wherein the thermal management system is fixed to the vehicle frame. The thermal management system can be used to thermally manage the passenger compartment of the electric vehicle, as well as the battery and / or motor electronic control unit of the electric vehicle. By improving the structure of the first heat exchange component in the thermal management system, the production and maintenance costs of the thermal management system and the electric vehicle are reduced, thereby enhancing the competitiveness of the electric vehicle.

[0021] In one technical solution, the housing includes a load-bearing plate, which is separately secured to the vehicle frame along with a flow channel plate. The flow channel plate and the load-bearing plate provide support at each end of the thermal management integrated module, further stabilizing the overall structure. In a specific implementation, the flow channel plate and the load-bearing plate are each secured to the vehicle frame via brackets. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. However, the example embodiments can be implemented in various forms and should not be understood as being limited to the embodiments set forth herein. The same reference numerals in the drawings represent the same or similar structures, and thus repeated description thereof will be omitted. The words expressing position and direction described in the embodiments of the present application are explained with the drawings as an example, but can be changed as needed, and the changes made are included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative positional relationship and do not represent the true proportion.

[0060] It should be noted that specific details are set forth in the following description in order to facilitate understanding of the present application. However, the present application can be implemented in various ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0061] To facilitate understanding of the technical solutions provided by the embodiments of this application, the following first introduces their application scenarios. In recent years, environmental pollution and energy shortages have accelerated the development and utilization of green and renewable energy. Electric vehicles, with their advantages of low pollution, low noise, and high energy efficiency, have become a research hotspot in the automotive industry. Electric vehicles include a thermal management system, which is typically used to cool / heat the passenger compartment, dissipate heat from the battery and power system, and recover waste heat. The thermal management system includes components such as a compressor, condenser, cooler, valve body, and water pump, with the various components interconnected by pipes. In one prior art, the condenser and cooler utilize a plate heat exchanger. The plate heat exchanger comprises multiple metal plates arranged at intervals and welded to form interconnected refrigerant and coolant flow channels. The refrigerant and coolant flow through the corresponding channels by convection, exchanging heat. Because the plate heat exchanger contains a large number of metal plates and requires welding between any two adjacent metal plates, the plate heat exchanger is complex in structure and expensive to produce, which in turn increases the production and maintenance costs of the thermal management system. The increase in the production cost of thermal management systems has also correspondingly increased the price of new energy vehicles, making it impossible to meet the consumption needs of some consumers. In the increasingly competitive market environment, this has affected the competitiveness of new energy vehicles.

[0062] In view of this, the embodiments of the present application provide a thermal management integrated module, a thermal management system and an electric vehicle, which are used to simplify the structure of the condenser or cooler, reduce the production cost of the condenser or cooler, and thus correspondingly reduce the production cost and maintenance cost of the thermal management system and the electric vehicle, which is beneficial to improving the competitiveness of the electric vehicle.

[0063] Figure 1 A structural diagram of an electric vehicle provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, in one embodiment, an electric vehicle includes a thermal management system 1 and a vehicle frame 2, wherein the thermal management system 1 is fixed to the vehicle frame 2. In one application scenario, the thermal management system 1 can be used to thermally manage the passenger compartment of the electric vehicle. In another application scenario, the thermal management system 1 can also be used to thermally manage at least one of the battery and the motor and electronic control unit of the electric vehicle. Specifically, the thermal management system 1 can heat, cool, or naturally cool the passenger compartment, battery, and motor and electronic control unit of the electric vehicle.

[0064] Figure 2 A schematic diagram of the structure of the thermal management system provided in the embodiment of the present application is shown as follows: Figure 2As shown, in one embodiment, the thermal management system 1 comprises a thermal management integrated module 10, a compressor 20 and a second heat exchange assembly 30. The thermal management integrated module 10 has a refrigerant flow path and a coolant flow path. The refrigerant flow path in the thermal management integrated module 10 can be connected to the compressor 20 through a refrigerant transmission pipeline and form a refrigerant loop. The coolant flow path in the thermal management integrated module 10 can be connected to the second heat exchange assembly 30 through a coolant transmission pipeline and form a coolant loop. The refrigerant and the coolant exchange heat when flowing through the thermal management integrated module 10.

[0065] It should be noted that the second heat exchange assembly 30 can be used to dissipate heat from some components in the electric vehicle. For example, the second heat exchange assembly 30 can be used to dissipate heat from the battery of the electric vehicle, and can also be used to dissipate heat from the motor control unit of the electric vehicle. In one embodiment, the second heat exchange assembly 30 is used to dissipate heat from the battery. When the above-mentioned second heat exchange assembly 30 is specifically arranged, the second heat exchange assembly 30 comprises a cold plate, which can be arranged at the bottom of the battery or at the side of the battery. The coolant exchanges heat with the battery when flowing through the cold plate, and the coolant absorbs the heat generated by the battery to reduce the temperature of the battery. The heat-absorbed coolant enters the thermal management integrated module 10 along the coolant transmission pipeline. In the thermal management integrated module 10, the coolant exchanges heat with the low-temperature refrigerant, and the coolant releases heat to the refrigerant to reduce the temperature. The low-temperature coolant returns to the cold plate along the coolant transmission pipeline again to continue dissipating heat from the battery.

[0066] It can be understood that, in addition to being used to dissipate heat from the battery, the above-mentioned second heat exchange assembly 30 can also be used to heat the battery in some application scenarios. For example, in winter, the above-mentioned second heat exchange assembly 30 can also be used to heat the battery to improve the performance of the battery.

[0067] In another embodiment, the second heat exchange assembly 30 is a front-end cooling module of the motor control unit, which is used to dissipate heat from the motor control unit. When the above-mentioned second heat exchange assembly 30 is specifically arranged, the second heat exchange assembly 30 comprises a fan and a radiator. The coolant exchanges heat with air when flowing through the radiator, and the temperature of the coolant decreases after releasing heat. The low-temperature coolant continues to flow, and the coolant absorbs heat generated by the motor control unit when flowing through the motor control unit, thereby achieving the effect of dissipating heat from the motor control unit. The fan can accelerate the flow of air around the radiator, improve the heat exchange efficiency between the coolant and the air, thereby further reducing the temperature of the coolant and improving the heat dissipation effect of the motor control unit.

[0068] Figure 3 A structural schematic diagram of the thermal management integrated module provided in the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the thermal management integrated module 10 comprises a housing 100, a refrigerant inlet 110, a refrigerant outlet 120, a coolant inlet 130 and a coolant outlet 140. The refrigerant inlet 110 and the refrigerant outlet 120 are arranged on one side of the housing 100, and the coolant inlet 130 and the coolant outlet 140 are arranged on the other side of the housing 100. The refrigerant inlet 110 and the refrigerant outlet 120 are connected to the compressor 20 through the refrigerant transmission pipeline, and the coolant inlet 130 and the coolant outlet 140 are connected to the second heat exchange assembly 30 through the coolant transmission pipeline. Figure 3As shown, in one embodiment, the thermal management integrated module 10 includes a first heat exchange component 100 and a flow channel plate 200 . Figure 4 This is an internal schematic diagram of the thermal management integrated module provided in the embodiment of the present application, such as Figure 4 As shown, in one embodiment, the first heat exchange assembly 100 includes a housing 110 and a heat exchange pipeline 120 located within the housing 110. The housing 110 is also used to contain a coolant, and at least a portion of the heat exchange pipeline 120 is located within the coolant. The heat exchange pipeline 120 has a first refrigerant inlet 1201 and a first refrigerant outlet 1202. The first refrigerant inlet 1201 is configured to communicate with a refrigerant transmission pipeline, and the end of the refrigerant transmission pipeline remote from the first refrigerant inlet 1201 can be connected to a compressor. The first refrigerant outlet 1202 is configured to communicate with another refrigerant transmission pipeline, and the end of the refrigerant transmission pipeline remote from the first refrigerant outlet 1202 can also be connected to a compressor. The refrigerant transmission pipeline can transmit refrigerant between the heat exchange pipeline 120 and the compressor. As the refrigerant flows through the heat exchange pipeline 120, heat is exchanged between the wall of the heat exchange pipeline 120 and the coolant within the housing 110, causing the temperature of the coolant to decrease or increase.

[0069] In order to improve the heat exchange effect between the refrigerant and the coolant, in a specific embodiment, the surface of the heat exchange pipe 120 has fins, which can increase the surface area of ​​the heat exchange pipe 120, thereby increasing the heat exchange area between the heat exchange pipe 120 and the coolant, thereby improving the heat exchange effect between the refrigerant and the coolant.

[0070] When specifically configuring the heat exchange pipeline 120, the heat exchange pipeline 120 can include various structural forms. For example, in one embodiment, the heat exchange pipeline 120 is a single, integral pipeline. In another embodiment, the heat exchange pipeline 120 comprises multiple segments, with adjacent segments welded, flanged, or threaded. The heat exchange pipeline 120 is used to circulate refrigerant. As the refrigerant flows through the heat exchange pipeline 120, it can exchange heat with the coolant within the housing 110 through the sidewalls of the heat exchange pipeline 120.

[0071] In the above-mentioned thermal management integrated module 10, by immersing the heat exchange pipe 120 in the coolant, the refrigerant can exchange heat with the coolant in the process of flowing through the heat exchange pipe 120. The plate exchange form of stacked welding is not used, which simplifies the structure of the first heat exchange component 100 and reduces the production cost of the first heat exchange component 100, thereby correspondingly reducing the production cost of the thermal management system 1 and the electric vehicle, thereby helping to enhance the competitiveness of the electric vehicle. In addition, since the first heat exchange component 100 has fewer parts, the first heat exchange component 100 is more convenient to repair and maintain. For example, during use, the box 110 and the heat exchange pipe 120 can be repaired or replaced separately to extend the service life of the first heat exchange component 100 and reduce the cost of use. During use, the above-mentioned first heat exchange component 100 can also correspondingly reduce the maintenance cost of the thermal management system and the electric vehicle, thereby helping to enhance the competitiveness of the electric vehicle.

[0072] For reference Figure 3 and Figure 4 , the box body 110 has two interfaces 1103, and the two ends of the heat exchange pipeline 120 are respectively connected to the refrigerant transmission pipeline through these two interfaces 1103. Specifically, the heat exchange pipeline 120 includes a liquid inlet end and a liquid outlet end. When the liquid inlet end and the refrigerant transmission pipeline are specifically connected, a variety of arrangements are included. For example, in one embodiment, the liquid inlet end passes through the corresponding interface 1103 and is exposed from the box body 110, and the part of the liquid inlet end exposed from the box body 110 is connected to the refrigerant transmission pipeline. For another example, in another embodiment, the liquid inlet end is completely located in the box body 110, and the refrigerant transmission pipeline extends into the box body 110 after passing through the corresponding interface 1103, and is connected to the liquid inlet end. For another example, in another embodiment, the liquid inlet end is completely located in the box body 110, and the liquid inlet end abuts against the first wall panel of the box body 110. Optionally, the liquid inlet end and the first wall panel can be fixed by welding, or the liquid inlet end and the first wall panel can also be fixed by a flange. The refrigerant transmission pipeline is located outside the box body 110 and is also in contact with the first wall panel of the box body 110. Similarly, the refrigerant transmission pipeline and the first wall panel can also be fixed by welding or flanges. The first wall panel is provided with the above-mentioned interface 1103, and the liquid inlet is connected to the refrigerant transmission pipeline through the interface 1103. Optionally, the first wall panel is a cover plate or a side panel of the box body 110. The cover plate is located on the side of the heat exchange pipeline 120 away from the flow channel plate 200, and the side panel is located on the peripheral side of the heat exchange pipeline 120.

[0073] When the liquid outlet of the heat exchange pipeline 120 is specifically connected to the refrigerant transmission pipeline, the liquid outlet and the corresponding refrigerant transmission pipeline can also be arranged in the above-mentioned manner, which is not described in detail in this application.

[0074] Please continue to refer to Figure 4The housing 110 further includes a coolant inlet 1101 and a coolant outlet 1102. Furthermore, the manifold plate 200 includes a first manifold opening 201 and a second manifold opening 202. The first manifold opening 201 communicates with the coolant inlet 1101, and the second manifold opening 202 communicates with the coolant outlet 1102. Coolant can flow from the manifold plate 200 to the housing 110, and coolant can also flow from the housing 110 to the manifold plate 200.

[0075] In addition to the first flow channel opening 201 and the second flow channel opening 202, the flow channel plate 200 also has a third flow channel opening 203, a fourth flow channel opening 204 and a plurality of flow channels 205. Among them, the third flow channel opening 203 and the fourth flow channel opening 204 are respectively connected to the second heat exchange component through the coolant transmission pipeline, so that the coolant can flow from the second heat exchange component to the flow channel plate 200, and can also flow from the flow channel plate 200 to the second heat exchange component. The plurality of flow channels 205 include flow channels corresponding to the first flow channel opening 201, the second flow channel opening 202, the third flow channel opening 203 and the fourth flow channel opening 204. In one application scenario, the plurality of flow channels 205 can connect the first flow channel opening 201 and the third flow channel opening 203, and connect the second flow channel opening 202 and the fourth flow channel opening 204, so that the second heat exchange component and the box body 110 are connected and a coolant circuit is formed. In a specific embodiment, the flow channel plate 200 is provided with a valve assembly 300, which is connected to the plurality of flow channels 205. The valve assembly 300 can switch the plurality of flow channels 205 between them, connecting the second heat exchange assembly and the housing 110 to form a coolant circuit, or disconnecting the second heat exchange assembly from the housing 110.

[0076] When specifically forming the flow channel 205, in one embodiment, the flow channel plate 200 includes a first substrate and a second substrate, wherein the second substrate is located on a side of the first substrate facing away from the heat exchange pipe 120. The first substrate has a plurality of first grooves on a side facing the second substrate, and / or the second substrate has a plurality of second grooves on a side facing the first substrate. The first and second substrates are fastened together, so that the first and / or second grooves form the flow channel 205.

[0077] When specifically configuring the valve body assembly 300, the valve body assembly 300 can include various types. For example, in one embodiment, the valve body assembly 300 includes a nine-way valve. In another embodiment, the valve body assembly 300 includes a five-way valve and a four-way valve. In yet another embodiment, the valve body assembly 300 includes an eight-way valve and a one-way valve. Of course, the valve body assembly 300 can also include other types of valve bodies, which are not listed in this application.

[0078] It is worth noting that when there are multiple second heat exchange components, the flow channel plate 200 accordingly has multiple pairs of third flow channels 203 and fourth flow channels 204, each pair of third flow channels 203 and fourth flow channels 204 being connected to the corresponding second heat exchange component via a coolant transmission pipeline. When the valve body assembly 300 switches between certain operating modes, it can change the on-off state between the multiple flow channels 205, thereby allowing at least one of the multiple second heat exchange components to connect to the housing 110 to form a loop, thereby allowing the second heat exchange component to dissipate heat or heat the corresponding component. In addition, the valve body assembly 300 also includes other operating modes, in which the third flow channel 203 and the fourth flow channel 204 can be directly connected through the valve body assembly 300. In other words, after the coolant flowing out of the liquid outlet of the second heat exchange component enters the flow channel plate 200 through the third flow channel 203, it can directly flow back to the liquid inlet of the second heat exchange component through the fourth flow channel 204 under the connection of the valve body assembly 300.

[0079] In the above-mentioned thermal management integrated module 10, the first heat exchange component 100 is located in both the refrigerant circuit and the coolant circuit, and the refrigerant and the coolant can exchange heat within the first heat exchange component 100. In one embodiment, the first heat exchange component 100 can serve as a condenser. The high-temperature and high-pressure gaseous refrigerant flowing out of the compressor 20 exchanges heat with the coolant in the housing 110 while flowing through the condenser. The gaseous refrigerant releases heat, its temperature decreases, and it condenses into a liquid state, while the coolant absorbs heat and its temperature increases. In one application scenario, the high-temperature coolant flows out of the housing 110 and enters the second heat exchange component through the flow channel plate 200. The second heat exchange component is the front-end cooling module of the motor electronic control unit. The coolant releases heat while flowing through the second heat exchange component, thereby reducing its temperature. The low-temperature coolant continues to flow and cools the motor electronic control unit while flowing through the motor electronic control unit. The coolant then returns to the condenser through the flow channel plate 200, completing a cycle. In another application scenario, high-temperature coolant enters the heater core to heat the passenger compartment. After flowing out of the heater core, the coolant returns to the condenser, completing a cycle.

[0080] In another embodiment, the first heat exchange component 100 can also serve as a cooler. In the refrigerant circuit, the low-temperature refrigerant will enter the cooler and perform heat exchange with the coolant in the box 110 while flowing through the cooler. After the refrigerant absorbs heat, its temperature rises and its phase changes to gas. The gaseous refrigerant continues to flow and enters the compressor 20, while the coolant releases heat and its temperature drops. In one application scenario, the low-temperature coolant flows out of the box 110 and enters the second heat exchange component through the flow channel plate 200. The second heat exchange component is used to dissipate heat to the battery. The coolant absorbs heat while flowing through the second heat exchange component, thereby increasing its temperature. The high-temperature coolant continues to flow and returns to the cooler again through the flow channel plate 200, completing a cycle.

[0081] In the thermal management integrated module 10, the housing 110 and the flow channel plate 200 of the first heat exchange component 100 are connected, and there are multiple connection methods. For example, in one embodiment, a refrigerant substrate is provided between the housing 110 and the flow channel plate 200, and the housing 110 and the flow channel plate 200 are respectively connected to the refrigerant substrate, or in other words, the housing 110 and the flow channel plate 200 are indirectly connected through the refrigerant substrate. It should be noted that a refrigerant flow channel is provided in the refrigerant substrate, and the refrigerant flow channel is connected to the heat exchange pipeline 120, and the refrigerant flow channel is connected to the compressor. The refrigerant substrate is also provided with a plurality of hollow structures, and the first flow channel opening 201 and the second flow channel opening 202 of the flow channel plate 200 are respectively provided with quick-connect plugs, which pass through the hollow structure and dock with the coolant inlet 1101 and the coolant outlet 1102 of the housing 110.

[0082] For example, Figure 3 and Figure 4 As shown, in another embodiment, the housing 110 and the flow channel plate 200 of the first heat exchange component 100 are arranged adjacent to each other and are connected, rather than being indirectly connected through a refrigerant substrate. Specifically, the housing 110 and the flow channel plate 200 can be welded. Alternatively, the housing 110 and the flow channel plate 200 can also be connected by fasteners. Optionally, the fasteners are screws, bolts or rivets. In the above embodiment, the refrigerant substrate is eliminated between the housing 110 and the flow channel plate 200. After eliminating the refrigerant substrate, the structure of the thermal management integrated module 10 is simplified, the weight of the thermal management integrated module 10 is reduced, and the volume of the thermal management integrated module 10 is reduced, which can further optimize the interior space and performance of the electric vehicle.

[0083] When the box body 110 of the first heat exchange assembly 100 is specifically arranged, the box body 110 includes various structural forms. Figure 4 As shown, in one embodiment, the housing 110 includes a cover plate 111, a side plate 112, and a bottom plate 113. The cover plate 111 is located on the side of the heat exchange pipe 120 away from the flow channel plate 200, and the bottom plate 113 is located on the side of the heat exchange pipe 120 close to the flow channel plate 200. The side plate 112 is located between the cover plate 111 and the bottom plate 113, and the side plate 112 is arranged around the heat exchange pipe 120. In a specific embodiment, the bottom plate 113 is provided with a coolant inlet 1101 and a coolant outlet 1102. The position of the coolant inlet 1101 corresponds to the position of the first flow channel opening 201, and the position of the coolant outlet 1102 corresponds to the position of the second flow channel opening 202. The first flow channel opening 201 and the second flow channel opening 202 are respectively provided with quick-connect plugs, which are inserted into the coolant inlet 1101 and the coolant outlet 1102, so that the flow channel plate 200 and the housing 110 are connected.

[0084] In a specific implementation, the bottom plate 113 can be fixed to the flow channel plate 200 by fasteners. Optionally, the fasteners are screws, bolts or rivets. The bottom plate 113 and the side plate 112 can be an integral structure, thereby improving the sealing effect of the box 110 and reducing the risk of liquid leakage of the box 110.

[0085] Figure 5 Another internal schematic diagram of the heat management integrated module provided by the embodiment of the present application is shown in FIG. 6. Compared with the first heat exchange assembly 100 shown in FIG. 5, both of them include a cover plate 111 and a side plate 112. Figure 5 Compared with the first heat exchange assembly 100 shown in FIG. 5, the first heat exchange assembly 100 provided by the embodiment includes a flow channel plate 200. Figure 4 Compared with the first heat exchange assembly 100 shown in FIG. 5, the first heat exchange assembly 100 provided by the embodiment includes a flow channel plate 200. Figure 4 Compared with the first heat exchange assembly 100 shown in FIG. 5, the first heat exchange assembly 100 provided by the embodiment includes a flow channel plate 200. Compared with the first heat exchange assembly 100 shown in FIG. 5, the first heat exchange assembly 100 provided by the embodiment includes a flow channel plate 200.

[0086] In the process of connecting the flow channel plate 200 and the side plate 112 of the box 110, there are multiple connection methods. As shown in FIG. 7, in one embodiment, the flow channel plate 200 includes a first base plate 210, the first base plate 210 is arranged towards the heat exchange pipeline 120, and the first flow channel port 201 and the second flow channel port 202 are located on the first base plate 210. Among them, the first base plate 210 and the side plate 112 are an integral structure. Figure 5 In the process of connecting the flow channel plate 200 and the side plate 112 of the box 110, there are multiple connection methods. As shown in FIG. 7, in one embodiment, the flow channel plate 200 includes a first base plate 210, the first base plate 210 is arranged towards the heat exchange pipeline 120, and the first flow channel port 201 and the second flow channel port 202 are located on the first base plate 210. Among them, the first base plate 210 and the side plate 112 are an integral structure.

[0087] In another embodiment, the side plate 112 and the flow channel plate 200 can be bonded by glue or connected by fasteners. Optionally, the fasteners are screws, bolts or rivets.

[0088] When assembling the cover 111 and side panels 112 of the box 110, a protrusion is provided on the end of the side panel 112 near the cover 111. The cover 111 covers the protrusion, and the cover 111 and the protrusion are connected by fasteners. Optionally, the fasteners are screws, bolts, or rivets. A sealing gasket is provided between the cover 111 and the side panels 112, thereby improving the sealing effect of the box 110 and reducing the risk of leakage from the box 110.

[0089] When the heat exchange pipe 120 of the first heat exchange assembly 100 is specifically arranged, the heat exchange pipe 120 includes various structural forms. Figure 5 As shown, in one embodiment, the heat exchange pipeline 120 includes a first header 121, a second header 122, and multiple branch pipes 123. Specifically, the first refrigerant inlet 1201 of the heat exchange pipeline 120 is located in the first header 121, the first refrigerant outlet 1202 of the heat exchange pipeline 120 is located in the second header 122, and the branch pipes 123 connect the first header 121 and the second header 122. In the specific arrangement of the pipelines, the first header 121 and the second header 122 extend in parallel or nearly parallel directions, and the multiple branch pipes 123 are arranged at intervals along the extension direction of the first header 121 or the extension direction of the second header 122. When the refrigerant flows through the above-mentioned heat exchange pipeline 120, the refrigerant first enters the first liquid collecting pipe 121; after flowing out of the first liquid collecting pipe 121, the refrigerant forms multiple branches and enters the corresponding branch pipes 123; when flowing through the branch pipes 123, the refrigerant exchanges heat with the pipe wall of the branch pipe 123 and the coolant outside the branch pipe 123; the refrigerant in each branch pipe 123 enters the second liquid collecting pipe 122 and then gathers and flows out.

[0090] In other embodiments, the heat exchange pipeline 120 may also be a serpentine pipeline. This serpentine pipeline can increase the length of the pipeline within a certain space, extend the flow path of the refrigerant, and thus improve the heat exchange effect between the refrigerant and the coolant. The serpentine pipeline can be formed by connecting multiple sections of pipelines, and adjacent sections of pipelines can be welded or connected by flanges.

[0091] When the branch pipe 123 is specifically set, the branch pipe 123 can be formed into a microchannel by reducing the flow area of ​​the branch pipe 123, thereby reducing the flow of the refrigerant in the branch pipe 123, so that less refrigerant liquid can more fully exchange heat with the coolant in the process of flowing through the branch pipe 123, thereby improving the heat exchange efficiency between the refrigerant and the coolant. In addition, the distance between two adjacent branch pipes 123 can be increased accordingly to increase the flow of coolant between the two adjacent branch pipes 123, so as to further improve the heat exchange efficiency between the refrigerant and the refrigerant liquid. The branch pipe 123 includes a variety of structural forms, for example, Figure 5As shown, in one embodiment, the branch pipe 123 can be a flat branch pipe. In other embodiments, the branch pipe 123 can also be a cylindrical branch pipe or a square branch pipe. Of course, the branch pipe 123 can also be a branch pipe of other structural forms, which are not listed one by one in this application.

[0092] In order to improve the heat exchange efficiency between the refrigerant and the coolant, the surface of the branch pipe 123 is provided with fins 1230. The fins 1230 can increase the surface area of ​​the branch pipe 123, thereby increasing the heat exchange area between the branch pipe 123 and the coolant, thereby improving the heat exchange efficiency between the refrigerant and the coolant. In the specific arrangement, a group of fins 1230 is provided between any two adjacent branch pipes 123, and the two ends of each fin 1230 are respectively connected to the side walls of the two branch pipes 123. The multiple fins 1230 are arranged in sequence along the extension direction of the branch pipe 123, and the gaps between the two adjacent fins 1230 form a coolant flow channel. Optionally, the multiple fins 1230 are connected end to end to form a zigzag shape. In specific implementation, the spacing between the two adjacent branch pipes 123 can be increased to increase the installation space of the fins 1230, so that fins 1230 with a larger surface area can be selected to further improve the heat transfer efficiency between the refrigerant and the coolant.

[0093] When the heat exchange pipe 120 is assembled in the housing 110 , the heat exchange pipe 120 may be fixed to a wall panel of the housing 110 , thereby improving the stability of the heat exchange pipe 120 . Figure 6 A structural diagram of the first heat exchange component provided in an embodiment of the present application is shown as follows: Figure 6 As shown, in one embodiment, the box body 110 includes a load-bearing plate 114, which is used to connect to the vehicle frame, and the heat exchange pipeline 120 is fixed to the load-bearing plate 114. Optionally, the load-bearing plate 114 can be the cover plate 111 of the box body 110, or can be the side plate 112 of the box body 110.

[0094] When the heat exchange pipe 120 is fixed to the bearing plate 114, there are multiple fixing methods. Figure 6 As shown, in one fixing method, the liquid inlet end of the heat exchange pipe 120 is provided with a first flange 130, and the first flange 130 is fixedly connected to the bearing plate 114, thereby fixing the heat exchange pipe 120 relative to the box body 110. The bearing plate 114 is provided with an interface 1103, which is connected to the refrigerant inlet 1201.

[0095] Please continue to refer to Figure 6 In another fixing method, the liquid outlet of the heat exchange pipe 120 is provided with a second flange 140, and the second flange 140 is fixedly connected to the bearing plate 114, thereby fixing the heat exchange pipe 120 relative to the box body 110. The bearing plate 114 is provided with another interface 1103, which is connected to the refrigerant outlet 1202.

[0096] In one embodiment, flanges are provided at both the liquid inlet and outlet ends of the heat exchange pipe 120, and the ends of the heat exchange pipe 120 are connected to the bearing plate 114 via corresponding flanges. This fixing method can improve the fixing effect of the heat exchange pipe 120, making the heat exchange pipe 120 more stable. In another embodiment, a flange is provided at either the liquid inlet or the liquid outlet end of the heat exchange pipe 120, and the heat exchange pipe 120 is connected to the bearing plate 114 via corresponding flanges.

[0097] In other embodiments, the heat exchange pipeline 120 may also be fixed to the bearing plate 114 via a bracket.

[0098] When the load-bearing plate 114 is specifically set, the load-bearing plate 114 can be a metal plate or a plastic plate with greater structural strength. After the load-bearing plate 114 is fixed to the vehicle frame, it can play the role of supporting components such as the heat exchange pipeline 120 and the flow channel plate 200. In order to improve the stability of the thermal management integrated module 10, in one embodiment, the flow channel plate 200 is also fixed to the vehicle frame. The flow channel plate 200 and the load-bearing plate 114 can respectively play a supporting role at both ends of the thermal management integrated module 10, making the whole more stable. In specific implementation, the flow channel plate 200 and the load-bearing plate 114 are respectively fixed to the vehicle frame through brackets.

[0099] Figure 7 This is a schematic diagram of an application of the thermal management integrated module provided in the embodiment of the present application, such as Figure 7 As shown, in one embodiment, the thermal management integrated module 10 includes two first heat exchange assemblies 100, which are arranged in series between the inlet and liquid outlet of the compressor 20. The first heat exchange assembly 100 near the outlet of the compressor 20 can serve as a condenser, and the first heat exchange assembly 100 far from the outlet of the compressor 20 can serve as a cooler. For ease of description, the heat exchange pipelines 120 in the two first heat exchange assemblies 100 are respectively referred to as the first heat exchange pipeline 120a and the second heat exchange pipeline 120b, and the boxes 110 in the two first heat exchange assemblies 100 are respectively referred to as the first box 110a and the second box 110b. The first heat exchange pipeline 120a is located in the first box 110a, and the second heat exchange pipeline 120b is located in the second box 110b. In the refrigerant circuit, the first refrigerant inlet 1201 of the first heat exchange pipeline 120a is connected to the outlet of the compressor 20 through the refrigerant transmission pipeline, the first refrigerant outlet 1202 of the first heat exchange pipeline 120a is connected to the first refrigerant inlet 1201 of the second heat exchange pipeline 120b, and the first refrigerant outlet 1202 of the second heat exchange pipeline 120b is connected to the inlet of the compressor 20 through the refrigerant transmission pipeline.

[0100] Correspondingly, the flow channel plate 200 has two pairs of first flow channel openings 201 and second flow channel openings 202. One pair of first flow channel openings 201 and second flow channel openings 202 are respectively connected to the first box 110a, and the other pair of first flow channel openings 201 and second flow channel openings 202 are respectively connected to the second box 110b.

[0101] In the above embodiment, the first heat exchange pipeline 120a, the second heat exchange pipeline 120b, the compressor 20 and the refrigerant transmission pipeline form a refrigerant circuit. Of course, the refrigerant circuit also includes other components, such as a pump body and a valve body, etc., which are not listed one by one in this application. The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 20 enters the first heat exchange pipeline 120a through the refrigerant transmission pipeline. In the process of flowing through the first heat exchange pipeline 120a, the gaseous refrigerant and the coolant in the first box 110a perform heat exchange, the gaseous refrigerant releases heat and undergoes phase change, and condenses into a liquid. The liquid refrigerant continues to flow and enters the second heat exchange pipeline 120b. In the process of flowing through the second heat exchange pipeline 120b, the liquid refrigerant performs heat exchange with the coolant in the second box 110b. After absorbing heat, the temperature of the liquid refrigerant rises and the phase changes into a gaseous state. The gaseous refrigerant flows out of the second heat exchange pipeline 120 b and continues to flow along the refrigerant transmission pipeline back to the compressor 20 .

[0102] After the coolant and refrigerant in the first box 110a undergo heat exchange, the temperature of the coolant increases. In one application scenario, the high-temperature coolant can flow through the heater core to heat the passenger compartment. In another application scenario, the valve body assembly 300 switches to the first working mode. In the first working mode, the first box 110a is connected to the second heat exchange assembly 30 through the flow channel plate 200 to form a coolant circuit. The high-temperature coolant enters the second heat exchange assembly 30 through the flow channel plate 200. The coolant releases heat in the process of flowing through the second heat exchange assembly 30, thereby reducing the temperature. The low-temperature coolant flows back into the first box 110a through the flow channel plate 200 again. The above-mentioned second heat exchange assembly 30 can be used as a front-end cooling module of the motor electronic control unit.

[0103] After the coolant and refrigerant in the second box 110b undergo heat exchange, the temperature of the coolant decreases. In one application scenario, the valve body assembly 300 switches to the second working mode. In the second working mode, the second box 110b is connected to another second heat exchange assembly 30 through the flow channel plate 200 to form a coolant circuit. The second heat exchange assembly 30 is used to dissipate heat for the battery. The low-temperature coolant enters the second heat exchange assembly 30 through the flow channel plate 200. The coolant absorbs heat and its temperature rises in the process of flowing through the second heat exchange assembly 30, which reduces the temperature of the battery. The high-temperature coolant flows back to the second box 110b through the flow channel plate 200 again.

[0104] When the two first heat exchange components 100 are specifically arranged, as shown in FIG. Figure 3As shown, in one embodiment, the two first heat exchange assemblies 100 are located on the side of the flow channel plate 200 away from the valve body assembly 300. In other words, the two first heat exchange assemblies 100 and the valve body assembly 300 are respectively located on opposite sides of the flow channel plate 200. In the above embodiment, the first heat exchange assembly 100 and the valve body assembly 300 can make full use of the space on both sides of the flow channel plate 200 for arrangement, and there will be no interference in space, making the layout more reasonable. In addition, the two first heat exchange assemblies 100 are located on the same side of the flow channel plate 200, thereby shortening the communication path between the two first heat exchange assemblies 100, making it more convenient to arrange the pipeline to connect the heat exchange pipeline 120 of the two first heat exchange assemblies 100.

[0105] Figure 8 A schematic diagram of a combination of two first heat exchange components provided in an embodiment of the present application, such as Figure 8 As shown, in one embodiment, the first housing 110a includes a first cover plate 111a, which is located on the side of the first heat exchange pipeline 120a away from the flow channel plate 200. The second housing 110b includes a second cover plate 111b, which is located on the side of the second heat exchange pipeline 120b away from the flow channel plate 200. The first cover plate 111a and the second cover plate 111b are independent structures. Since the first cover plate 111a and the second cover plate 111b are independent structures, the areas of the first cover plate 111a and the second cover plate 111b are smaller, so that the flatness of the first cover plate 111a and the second cover plate 111b is easier to control during the production process, thereby improving the sealing effect between the first cover plate 111a and the second cover plate 111b and the corresponding side plates.

[0106] Figure 9 Another schematic diagram of the combination of two first heat exchange components provided in the embodiment of the present application is as follows: Figure 9 As shown, the structures of the two first heat exchange components 100 provided in this embodiment are Figure 8 The two first heat exchange assemblies 100 shown have essentially the same structure, wherein the first housing 110a also includes a first cover plate 111a, and the second housing 110b also includes a second cover plate 111b. The difference is that in this embodiment, the first cover plate 111a and the second cover plate 111b are integrally formed. In the above embodiment, by forming the first cover plate 111a and the second cover plate 111b into an integral structure, the processing and installation steps of the cover plate 111 can be simplified, thereby improving production efficiency.

[0107] In the above embodiment, a sealing gasket is provided between the first cover plate 111a and the side plate 112 connected thereto, and a sealing gasket is also provided between the second cover plate 111b and the side plate 112 connected thereto, thereby improving the sealing effect of the box body 110 and reducing the risk of leakage of the box body 110.

[0108] Figure 10 Another schematic diagram of a combination of two first heat exchange components provided in an embodiment of the present application is as follows: Figure 10 As shown, in one embodiment, the first box 110a and the second box 110b include a shared partition 115, which is located between the first heat exchange pipeline 120a and the second heat exchange pipeline 120b. The partition 115 serves to separate the coolant, so that the coolant in the first box 110a and the coolant in the second box 110b do not mix. The partition 115 shared by the first box 110a and the second box 110b reduces the number of parts and reduces the weight of the first heat exchange assembly 100. At the same time, the partition 115 is also conducive to increasing the internal space of the first box 110a and the second box 110b, thereby accommodating more coolant and a larger volume of heat exchange pipeline, thereby improving the heat exchange effect between the refrigerant and the coolant.

[0109] Please continue to refer to Figure 10 In one embodiment, the first housing 110a includes a first side panel 112a, which is connected to a partition 115 and is disposed around the first heat exchange pipe 120a. The second housing 110b includes a second side panel 112b, which is connected to a partition 115 and is disposed around the second heat exchange pipe 120b. When the first side panel 112a and the second side panel 112b are specifically arranged, the first side panel 112a and the second side panel 112b can be an integral structure, thereby increasing the structural strength of the housing 110, improving the sealing effect of the housing 110, and reducing the risk of leakage from the housing 110.

[0110] In other embodiments, the side panels 112 of the first box 110a and the side panels 112 of the second box 110b can be independent of each other. Alternatively, the side panels 112 of the first box 110a can form an independent frame structure, and the side panels 112 of the second box 110b can form another independent frame structure. In specific arrangements, the two frame structures can be placed adjacent to each other or spaced apart.

[0111] Please continue to refer to Figure 10In one embodiment, the thermal management integrated module 10 further includes an expansion valve 400, which is fixed to the first housing 110a and the second housing 110b. The expansion valve 400 connects the first heat exchange pipeline 120a and the second heat exchange pipeline 120b, and can regulate the flow of refrigerant from the first heat exchange pipeline 120a to the second heat exchange pipeline 120b. In a specific implementation, the first housing 110a has a first interface 1103a, which is connected to the first refrigerant outlet 1202 of the first heat exchange pipeline 120a. The second housing 110b has a second interface 1103b, which is connected to the first refrigerant inlet 1201 of the second heat exchange pipeline 120b. The expansion valve 400 has a first valve port 401 and a second valve port 402. The first valve port 401 covers and communicates with the first port 1103a. In other words, the orthographic projection of the first valve port 401 on the plane where the first cover plate 111a is located at least partially overlaps with the first port 1103a. The second valve port 402 covers and communicates with the second port 1103b. In other words, the orthographic projection of the second valve port 402 on the plane where the second cover plate 111b is located at least partially overlaps with the second port 1103b.

[0112] In the above embodiment, there is no need to set a refrigerant transmission pipeline between the expansion valve 400 and the first heat exchange pipeline 120a and between the expansion valve 400 and the second heat exchange pipeline 120b, thereby simplifying the structure of the thermal management integrated module 10 and reducing the risk of refrigerant leakage during transmission.

[0113] When the expansion valve 400 is specifically set, Figure 10 As shown, in one embodiment, the expansion valve 400 includes a base 410 and a valve body 420, wherein the base 410 has a first flow channel 411 and a second flow channel 412, and the first flow channel 411 and the second flow channel 412 are respectively connected to the valve body 420. The first valve port 401 is located at the end of the first flow channel 411 away from the valve body 420, and the second valve port 402 is located at the end of the second flow channel 412 away from the valve body 420. The valve body 420 is specifically used to regulate the flow of refrigerant from the first heat exchange pipeline 120a to the second heat exchange pipeline 120b.

[0114] When specifically fixing and installing the base 410, the base 410 can be simultaneously fixed to the side of the first cover plate 111a facing away from the first heat exchange pipeline 120a, and the side of the second cover plate 111b facing away from the second heat exchange pipeline 120b. When specifically connecting the first flow channel 411 of the base 410 and the first heat exchange pipeline 120a, the first valve port 401 is located on the side of the base 410 facing the first cover plate 111a, and the first valve port 401 covers the first interface 1103a of the first cover plate 111a. The liquid outlet end of the first heat exchange pipeline 120a abuts the first cover plate 111a and is also connected to the first interface 1103a of the first cover plate 111a. In a specific embodiment, the liquid outlet end of the first heat exchange pipeline 120a is provided with a first flange, which is fixedly connected to the first cover plate 111a by bolts. Optionally, the bolts also pass through the base 410 , so that the base 410 , the first cover plate 111 a and the first heat exchange pipeline 120 a are fixed together.

[0115] When specifically connecting the second flow channel 412 of the base 410 to the second heat exchange pipeline 120b, reference can be made to the connection method between the first flow channel 411 and the first heat exchange pipeline 120a, and this application will not elaborate on this. The flow channel inside the base 410 serves to transmit refrigerant between the heat exchange pipeline 120 and the valve body 420. Due to the strong structural strength of the base 410, it can withstand high fluid pressure, thereby reducing the risk of refrigerant leakage.

[0116] To improve the sealing between base 410 and first cover plate 111a, and between base 410 and second cover plate 111b, a sealing gasket is provided between base 410 and first cover plate 111a, and between base 410 and second cover plate 111b. The sealing gasket can improve the sealing between base 410 and the corresponding cover plate, reducing the risk of refrigerant leakage.

[0117] Figure 11 A schematic diagram of a combination of two first heat exchange components and a liquid storage tank provided in an embodiment of the present application, such as Figure 11 As shown, in one embodiment, the thermal management integrated module 10 further includes a liquid storage tank 500, which is located within the first housing 110a. The liquid storage tank 500 has a second refrigerant inlet and a second refrigerant outlet, wherein the second refrigerant inlet is connected to the first refrigerant outlet 1202 of the first heat exchange pipeline 120a, and the second refrigerant outlet is connected to the first refrigerant inlet 1201 of the second heat exchange pipeline 120b. The liquid storage tank 500 can store the refrigerant flowing out of the first heat exchange pipeline 120a. The liquid storage tank 500 facilitates the separation of liquid refrigerant and gaseous refrigerant, allowing the liquid refrigerant to enter the second heat exchange pipeline 120b.

[0118] In the above embodiment, by arranging the liquid storage tank 500 in the first box body 110a, the communication path between the liquid storage tank 500 and the first heat exchange pipeline 120a can be shortened, the structure of the thermal management integrated module can be simplified, and the overall space occupied can be reduced. In another embodiment, the liquid storage tank 500 can also be located outside the first box body 110a.

[0119] Obviously, various modifications and changes can be made to the present application by those skilled in the art without departing from the spirit and scope of the present application. Thus, it is intended that the present application cover the modifications and changes as long as they come within the scope of the claims of the present application and their equivalents.
