[0033] Combine Figures 1-9 In the first specific embodiment of the present application, the thermal management module includes a first flow channel plate assembly 10 and a second flow channel plate assembly 20. The first flow channel plate assembly 10 is a plate-shaped structure, defining a first plane. The first flow channel plate assembly 10 extends in the first plane. Along the direction in which the first flow channel plate assembly 10 extends, at least part of the second flow channel plate assembly 20 is located on one side of the first flow channel plate assembly; the first flow channel plate assembly 10 includes a refrigerant flow channel 104 and a first coolant flow channel 105, and the second flow channel plate assembly 20 includes a second coolant flow channel 201. The first flow channel plate assembly 10 and the second flow channel plate assembly 20 are fixedly connected or limit-connected, and the first coolant flow channel 105 and the second coolant flow channel 201 are connected. It should be noted that the first flow channel plate assembly is a plate-shaped structure and extends in the first plane, that is, the extension of the first flow channel plate assembly in the first plane is greater than its extension in the vertical direction, such as Figure 3 As shown, a first direction and a second direction are defined, and the first direction and the second direction form a certain angle. In this embodiment, the first direction and the second direction are perpendicular to each other, and the first direction and the second direction constitute a first plane. The normal direction perpendicular to the first plane is the third direction. In this embodiment, the first flow channel plate assembly 10 is roughly a plate-shaped structure, the first direction is the length direction of the flow channel plate assembly, the second direction is the width direction of the first flow channel plate assembly 10, and the third direction is the height direction of the first flow channel plate assembly 10. In this embodiment, the coolant integrated module 200 and the refrigerant integrated module 100 are arranged along the first direction or the second direction. The first flow channel plate assembly 10 includes a refrigerant flow channel 104 and a first coolant flow channel 105, and the second flow channel plate assembly 20 includes a second coolant flow channel 201. The refrigerant and the coolant exchange heat in the heat exchange assembly 11. The first flow channel plate assembly 10 and the second flow channel plate assembly 20 are fixedly connected or limit-connected, and the first coolant flow channel 105 and the second coolant flow channel 201 are connected. It should be noted that the first coolant flow channel 105 and the second coolant flow channel 201 are connected, which can be direct connection, that is, the first flow channel plate assembly 10 and the second flow channel plate assembly 20 are directly fixedly connected, and the ports can be fixed by relative welding, or it can be indirect connection, that is, the first flow channel plate assembly 10 and the second flow channel plate assembly 20 are fixedly connected through an external adapter block and the internal flow channels are used together.

[0034] The plane formed by the first and third directions, or the second and third directions, is defined as a second plane. The orthographic projections of the coolant integrated module 200 and the refrigerant integrated module 100 on the second plane overlap. In this solution, the coolant integrated module 200 and the refrigerant integrated module 100 overlap as much as possible in the second plane, reducing the space occupied by the thermal management module in the longitudinal direction and in the third direction.

[0035] In the present application, the refrigerant integrated module 100 includes multiple thermal management components, which are located at the end of the first flow channel plate assembly 10 along the third direction. The coolant integrated module 200 includes multiple fluid control elements, which are located at the end of the second flow channel plate assembly 20 along the third direction. That is, along the third direction, the thermal management components in the refrigerant integrated module 100, such as the heat exchange assembly 11, valve component 3, liquid reservoir 4, compressor 5, etc., are distributed on the upper and lower sides of the first flow channel plate assembly 10. This fully utilizes the space around the first flow channel plate assembly 10 to arrange the thermal management components, making the structure of the thermal management integrated module more compact and facilitating the miniaturization of the thermal management integrated module.

[0036] like Figure 1 and Figure 2As shown, the compressor 5 and the accumulator 4 are located below the first flow channel plate assembly 10, and part of the heat exchange assembly 11 and the valve component 3 are located above the first flow channel plate assembly 10. Specifically, the heat exchanger assembly includes a first heat exchanger 111 and a second heat exchanger 112, wherein the first heat exchanger 111 is located below the first flow channel plate assembly 10, and the second heat exchanger 112 is located above the first flow channel plate assembly 10. If the first heat exchanger 111 is a condenser, one of the inlets of the condenser is connected to the outlet of the compressor 5. The condenser exchanges heat between the refrigerant discharged from the compressor 5 and one of the circuits in the coolant integrated module 200. The heat of the refrigerant discharged from the compressor 5 is dissipated to the coolant in the coolant integrated module 200, thereby heating the passenger compartment. The second heat exchanger 112 is an evaporator. The inlet of the evaporator is connected to the outlet of the condenser, and the outlet of the evaporator is connected to the inlet of the compressor 5. The refrigerant from the condenser enters the evaporator after being reduced in pressure by the expansion valve. The low-pressure refrigerant is connected to another circuit of the coolant integrated module 200, and the refrigerant and the coolant exchange heat, absorbing the heat of the coolant in the coolant integrated module 200, such as the battery circuit or the motor circuit, to cool the battery and motor. It can also be the refrigeration circuit of the air conditioner to cool the passenger compartment. The connection here includes direct connection or indirect connection. Indirect connection refers to connection through other thermal management components such as sensor 6, valve component 3, gas separator, etc. In the related art, multiple heat exchangers are placed on one side of the flow channel plate, and the layout and structure are relatively simple. The thermal management module occupies a large space in the horizontal direction, and the layout of the thermal management module in the vehicle is not flexible. The heat exchangers are arranged on both sides of the flow channel plate, which relatively reduces the horizontal space for arrangement and makes the thermal management module more compact.

[0037] The first flow channel plate assembly 10 includes a first coolant flow channel 105 and a refrigerant flow channel 104. The first heat exchanger 111 has four ports, two of which are connected to the refrigerant flow channel 104, and the other two ports are connected to the first coolant flow channel 105. The coolant in the first coolant flow channel 105 and the refrigerant in the refrigerant flow channel 104 perform heat exchange in the first heat exchanger 111. Similarly, the second heat exchanger 112 also has four ports, two of which are connected to another refrigerant flow channel 104, and the other two ports are connected to another first coolant flow channel 105. In this embodiment, the first flow channel plate assembly 10 includes a first coolant flow channel 105 and a refrigerant flow channel 104. In related art, only the refrigerant flow channel 104 is integrated into the flow channel plate on the agent side. Pipes are often used to connect the coolant side of the heat exchanger to the coolant integrated module 200. As the integrated modules on the coolant side become increasingly complex, more and more pipes are used, making installation difficult and occupying a large amount of vehicle space. The coolant flow channel is integrated into the flow channel plate on the agent side, reducing the need for pipes. Furthermore, the four ports of the heat exchanger are all arranged on the same side and sealed to the port end face of the flow channel plate on the agent side. This makes the heat exchanger relatively simple in structure and installation.

[0038] like Figure 3-Figure 5 As shown, the first flow channel plate assembly 10 includes a first plate 101, a second plate 102, and a third plate 103. Along the third direction, the first plate 101 is fixedly connected to the second plate 102, and the second plate 102 is fixedly connected to the third plate 103. The first plate 101, the second plate 102, and the third plate 103 cooperate to form a two-layer flow channel. In some embodiments, the first plate 101 has a first concave cavity 1011, and the third plate 103 has a third concave cavity. The first concave cavity 1011 of the first plate 101 and the third concave cavity 1031 of the third plate 103 are both facing the second plate 102. The second plate 102 can be provided with a second concave cavity, or it can be a flat plate. The first plate 101 and the second plate 102 cooperate to form a first layer of flow channel, and the second plate 102 and the third plate 103 cooperate to form a second layer of flow channel; in other embodiments, along the third direction, the two opposite ends of the second plate 102 are provided with second concave cavities (not shown in the figure). The first plate 101 and the third plate 103 can be provided with concave cavities, or they can be flat plates. The second plate 102 cooperates with the first plate 101 to form a first layer of flow channel, and the first plate 101 and the second plate 102 cooperate to form a second layer of flow channel. Of course, the form and structure of the first flow channel plate assembly 10 include but are not limited to the above-mentioned schemes. As long as the schemes that can realize two layers of flow channels or more than two layers are included in the scope of this application. The first flow channel plate assembly 10 sets two layers of flow channels or more layers of flow channels in the third direction, which makes the structure of the first flow channel plate more compact, reduces its lateral size, that is, the first direction, and makes the layout of the heat exchanger more flexible, not limited to being arranged on the same side of the flow channel plate. The coolant flow channel and the refrigerant flow channel 104 of the first flow channel plate assembly 10 are arranged in different positions according to different systems. The refrigerant flow channel 104 is generally set separately as the low-pressure side flow channel, the medium-pressure side flow channel and the high-pressure side flow channel to reduce heat loss. In some embodiments, insulation grooves are set between adjacent low-pressure, medium-pressure and high-pressure areas on the flow channel plate to reduce heat loss.

[0039] The refrigerant integrated module 100 also includes valve components 3. In this embodiment, multiple valve components 3 are disposed above the first flow channel plate assembly 10. The valve components 3 primarily control the opening and closing of the refrigerant flow channel 104, changing the direction of refrigerant flow, or adjusting the refrigerant flow rate within the refrigerant flow channel 104. The number and placement of the valve components 3 depend on the system mode and will not be described in detail here.

[0040] The refrigerant integrated module 100 further includes a sensor 6 for measuring the temperature and pressure of the refrigerant in the flow channel.

[0041] In the present application, the refrigerant integrated module 100 also includes an air supply and reheat increase module, which is arranged downstream of the liquid reservoir 4. The air supply and reheat increase module includes a third heat exchanger 113, and the third heat exchanger 113 is located above the first flow channel plate assembly 10, and the third heat exchanger 113 is fixedly connected or limit-connected to the first flow channel plate assembly 10.

[0042] Combine Figure 1-Figure 2 As shown, the thermal management module also includes a connecting assembly 300. The first flow plate assembly 10 is located on one side of the connecting assembly 300, and the second flow plate assembly 20 is located on the opposite side of the connecting assembly 300. The connecting assembly 300 is fixedly or positionally connected to the second flow plate assembly 20, and the connecting assembly 300 is fixedly or positionally connected to the first flow plate assembly 10. The connecting assembly 300 includes a flow channel 30, which is in communication with the first coolant flow channel 105, and the flow channel 30 is in communication with the second coolant flow channel 20. In this embodiment, the second flow plate assembly 20 includes a plurality of flow plates, which are stacked and fixedly connected in sequence along a third direction. The fluid control element includes a valve assembly 22 and a pump assembly 21. Along the third direction, the valve assembly 22 is located at the upper end of the second flow plate assembly 20, and the pump assembly 21 is located at the lower end of the second flow plate assembly 20.

[0043] like Figure 6-7As shown, the second flow channel plate assembly 20 includes a second coolant flow channel 201, the second flow channel plate assembly 20 has a valve installation cavity, part of the valve is located in the valve installation cavity, the valve assembly 22 is fixedly connected or limitedly connected to the second flow channel plate assembly 20, and the valve assembly 22 is used to control the switching of the coolant flow channel; the second flow channel plate assembly 20 includes a pump installation cavity 211, part of the pump is located in the pump installation cavity 211, and the pump is fixedly connected or limitedly connected to the second flow channel plate assembly 20; the plane formed by the second direction and the third direction is defined as the second plane, and the projection of the coolant integrated module 200 on the second plane partially overlaps with the projection of the refrigerant integrated module 100 on the second plane. Along the third direction, the second flow channel plate assembly 20 includes multiple layers of second coolant flow channels 201. The stacking design of the multiple layers of coolant flow channels relatively reduces the extension of the coolant flow channels in the first plane, so that the layout size of the second flow channel plate assembly 20 in the horizontal direction, i.e., the first plane, is relatively reduced. Along the third direction, the second flow channel plate assembly 20 includes an upper end and a lower end, and the thermal management component is arranged at the upper end and / or the lower end. The above-mentioned fluid control element includes a valve assembly 22 and a pump assembly 21, such as the valve assembly 22 is located at the upper end and the pump assembly 21 is located at the lower end, or at least part of the valve assembly 22 is located at the upper end and at least part of the pump assembly 21 is located at the lower end. In short, the valve assembly 22 and the pump assembly 21 are distributed at the upper end and the lower end of the second flow channel plate assembly 20, that is, arranged along the third direction. This can reduce the layout space in the first direction and make full use of the longitudinal space. It can be understood that in the refrigerant integrated module 100, the thermal management components are arranged at both ends of the first flow channel plate assembly 10 along the third direction, and in the coolant integrated module, the thermal management components are arranged at both ends of the second flow channel plate along the third direction, which can fully benefit the space and relatively reduce the horizontal size of the thermal management module.

[0044] The coolant integrated module 200 has multiple first interfaces 202, and the multiple first interfaces 202 are located on the same side of the second flow channel plate assembly 20. The refrigerant module has multiple fourth interfaces 106, and the multiple fourth interfaces 106 are located on the same side of the first flow channel plate assembly 10. The connection assembly 300 has multiple second interfaces 301 and multiple third interfaces 302. The multiple first interfaces 202 and the multiple second interfaces 301 are arranged in a one-to-one correspondence, and the multiple third interfaces 302 and the multiple fourth interfaces 106 are arranged in a one-to-one correspondence. The opening direction of the first interface 202 is set relative to the opening direction of the second interface 301, and the opening direction of the third interface 302 is set relative to the opening direction of the fourth interface 106. Figure 6As shown, multiple first interfaces 202 are located on a side of the second manifold plate assembly 20 close to the refrigerant integrated module 100, and multiple fourth interfaces 106 are located on a side of the first manifold plate assembly 10 close to the first manifold plate assembly 10. The connection assembly 300 includes a first base 31 and a second base 32, at least one of which has a groove, and the first base 31 and the second base 32 cooperate to form a portion of the flow channel 30. In some implementations, multiple second interfaces 301 are located on a side of the first base 31 close to the second manifold plate assembly 20, and multiple third interfaces 302 are located on a side of the second base 32 close to the first manifold plate assembly 10. It can be understood that along the first direction, the second interfaces 301 and the third interfaces 302 are arranged opposite to each other, and the flow channel 30 connects the second interfaces 301 and the third interfaces 302. In this embodiment, the refrigerant integrated module 100 includes a first heat exchanger 111 and a second heat exchanger 112. Two ports of the first heat exchanger 111 communicate with the coolant flow channel of the coolant integrated module 200, and two ports of the first heat exchanger 111 communicate with the second coolant flow channel 201 of the coolant integrated module 200. Therefore, in this embodiment, the number of first interfaces 202 is four, and the corresponding number of second interfaces 301, third interfaces 302, fourth interfaces 106, and flow channels 30 are all four. The first interface 202 is sealed and fixedly connected to the second interface 301, and the third interface 302 is sealed and fixedly connected to the fourth interface 106. Methods of fixed connection include welding, bonding, etc.

[0045] In some other embodiments, such as Figure 8-9 As shown, the connection assembly 300 includes a first base 31 and a second base 32, at least one of which has a groove. The first base 31 and the second base 32 cooperate to form part of the flow channel 30. A first direction and a second direction are defined, and the first and second directions constitute a first plane. The first flow channel plate assembly 10 extends in the first plane, and a third direction is defined as a direction perpendicular to the first plane. The axial directions of the multiple third interfaces 302 of the connection assembly 300 are parallel to the third direction, and the multiple third interfaces 302 are arranged in parallel along the second direction. It is understood that the third interfaces are located at the ends of the first flow channel plate assembly along the third direction. Parallelism does not necessarily mean absolute parallelism, but rather is within the tolerance range.

[0046] Specifically, in this embodiment, along the first direction, the first base 31 has a first side portion 311 and a second side portion 312, and the side portion close to the second flow channel plate assembly 20 is defined as the first side portion 311. Along the third direction, the first base 31 has a first end portion 313 and a second end portion 314, and the groove of the first base 31 is defined as a first groove 315. The first groove 315 has an opening, and the opening of the first groove 315 faces the first flow channel plate assembly 10, that is, the first groove 315 is recessed inward along the end surface of the second side portion 312, and the first base 31 is welded and fixed to the second base 32, that is, the inner wall of the first groove 315 cooperates with part of the wall of the second base 32 to form part of the flow channel 30. The second interface 301 is located on the first base 31, and the second interface 301 is located on the first side 311 of the first base 31. The third interface 302 is located on the first base 31, and the third interface 302 is located on the first end 313 of the first base 31, and / or the third interface 302 is located on the second end 314 of the first base 31. To facilitate the connection between the multiple third interfaces 302 of the connecting assembly 300 and the multiple fourth interfaces 106 of the first flow channel plate assembly 10, in this embodiment, the multiple third interfaces 302 are arranged in parallel along the second direction. Correspondingly, the fourth interfaces 106 are located at the end of the first flow channel plate assembly 10 along the third direction and are arranged in parallel along the second direction. In this solution, the connecting assembly 300 and the first flow channel plate assembly 10 are fixed by a threaded connection. The first manifold plate assembly 10 has a first lug 107 with a mounting hole. The connecting assembly 300 has a threaded hole 316 disposed at the first end 313 of the connecting assembly 300. The connecting assembly 300 and the first manifold plate assembly 10 are threadedly fixedly connected along the third direction. In this embodiment, the third interface 302 of the connecting assembly 300 and the fourth interface 106 of the first manifold plate assembly 10 are disposed along the first direction, facilitating the threaded connection between the connecting assembly 300 and the first manifold plate assembly 10. Along the first direction, the coolant integrated assembly and the refrigerant integrated assembly are disposed on the left and right sides of the connecting assembly 300, respectively. If the threaded connection is disposed along the first direction, insufficient installation space would be required during assembly. The connecting component 300 and the second flow channel plate component 20 are fixedly connected by threads, and the second interface 301 of the connecting component 300 and the first interface 202 of the second flow channel plate component 20 are arranged along the first direction. In this embodiment, the second flow channel plate component 20 is injection molded, and multiple first interfaces 202 are arranged on the side of the second flow channel plate close to the connecting component 300. The second flow channel plate component 20 includes a second lug 203, and the second lug 203 is arranged along the second direction on the side of the second flow channel plate component 20 close to the connecting component 300. The second lug 203 has a threaded hole 316. The first base 31 of the connecting component 300 has a boss 317. The boss 317 is connected to the first side portion 311 of the first base 31. The boss 317 has a through hole. The bolt passes through the through hole on the boss 317 and is fixedly connected to the threaded hole 316 of the second flow channel plate component 20.

[0047] In other embodiments, the thermal management system is complex, and the connection component 300 has multiple flow channels 30, and the multiple flow channels 30 may be staggered. If the connection component 300 is only provided with a single-layer flow channel, in order to avoid the staggering of the flow channels 30, the volume of the connection component 300 becomes larger, which is not conducive to the miniaturization of the thermal management device. Therefore, in this solution, the connection component 300 includes a first substrate 31 and a second substrate 32. The first substrate 31 includes a built-in flow channel 318 and an external flow channel 319. The built-in flow channel 318 and the external flow channel 319 are not connected to each other. The first substrate 31 has a first groove 315. The opening of the first groove 315 faces the first flow channel plate assembly 10. The first groove 315 cooperates with the second substrate 32 to form a part of the external flow channel 319. Along the first direction, the built-in flow channel 318 is close to the second flow channel plate assembly 20 relative to the external flow channel 319, and the built-in flow channel 318 and the external flow channel 319 partially overlap in the orthographic projection on the second plane. As shown in FIG. Figure 8 As shown, the connection assembly 300 includes a third base 33, which is fixedly connected to the first base 31. The first base 31 and the third base 33 cooperate to form part of the internal flow channel 318. Specifically, in this embodiment, the first base 31 is integrally formed or has an integral structure. The first base 31 is formed by die-casting, forging, extrusion and stamping, and then the external flow channel 319 and the internal flow channel 318 are machined. The second base 32 and the third base 33 are flat plate structures. The first base 31 and the second base 32 are welded together, and the first base 31 and the third base 33 are welded together. Specific embodiment 2

[0049] Combine Figure 10-Figure 21In the second specific embodiment of the thermal management module of the present application, the refrigerant integrated module 100 includes, in addition to the first heat exchanger 111, the second heat exchanger 112 and the third heat exchanger 113 of the air replenishment and enthalpy increase module, a fourth heat exchanger 114. The fourth heat exchanger 114 is arranged above the first flow channel plate assembly 10 and is adjacent to the second heat exchanger 112. The fourth heat exchanger 114 has four ports, two of which are connected to the refrigerant flow channel 104, and the other two ports are connected to the coolant flow channel. The refrigerant in the refrigerant flow channel 104 and the coolant in the coolant flow channel perform heat exchange in the fourth heat exchanger 114. Compared with the first embodiment, the thermal management system in the second embodiment is more complex. The coolant integrated module and the refrigerant integrated module 100 have a total of three coolant circuits, that is, the coolant integrated module has six first interfaces 202, and the six first interfaces 202 are located on the side of the coolant integrated module 200 close to the connecting component 300. Similarly, the number of the second interface 301, the third interface 302 and the flow channel 30 of the connecting component 300 corresponds one-to-one to the number of the coolant integrated module 200, that is, 6, and the number of the fourth interface of the refrigerant integrated module 100 is 6. Along the first direction, the connecting component 300 is located between the coolant integrated module 200 and the refrigerant integrated module 100, one side of the connecting component 300 is fixedly or limit-connected to the coolant integrated module 200, and the other side of the connecting component 300 is fixedly or limit-connected to the refrigerant integrated module 100, the coolant flow channel of the coolant integrated module is correspondingly connected to the flow channel 30 of the connecting component 300, and the coolant flow channel of the refrigerant integrated module 100 is correspondingly connected to the flow channel 30 of the connecting component 300. It can also be understood that the coolant flow channel of the refrigerant integrated module 100 is connected to the coolant flow channel of the coolant integrated module 200 through the flow channel 30 of the connecting component 300.

[0050] like Figure 17-21As shown, the connection assembly 300 includes a first base 31, a second base 32, and a third base 33. Along a first direction, the first base 31 is located on one side of the second base 32, and the third base 33 is located on an opposite side of the second base 32. The first base 31 is fixedly connected to the second base 32, and the second base 32 is fixedly connected to the third base 33. At least one of the first base 31 and the second base 32 has a groove, and the first base 31 and the second base 32 cooperate to form a portion of the flow channel 30. In this embodiment, the groove of the first base 31 is defined as the first groove 315, and the groove of the second base 32 is defined as the second groove 321. The opening directions of the first groove 315 and the second groove 321 are arranged in opposite directions, and the walls forming the first groove 315 and the walls forming the second groove 321 cooperate to form a portion of the flow channel 30. The first base 31 has a second interface 301, which is located on a first side 311 of the first base 31 near the coolant integrated module 200. The second interface 301 communicates with the flow channel 30. The layout position of the second interface 301 corresponds one-to-one with the position of the first interface 202 of the coolant integrated module 200. It can be understood that the first interface 202 and the second interface 301 are coaxial or substantially coaxial. To facilitate the installation of the connecting assembly 300 and the first flow channel plate assembly 10, the third interface 302 of the connecting assembly 300 is arranged along the third direction. The third base 33 has a portion of the flow channel 30 inside, and the third interface 302 of the connecting assembly 300 is located on the third base 33. The following is a detailed description of one of the flow channels 30 of the connection assembly 300. For the convenience of description, one of the flow channels 30 of the connection assembly 300 is defined as a first channel 303. The first channel 303 includes a first sub-channel 3031 and a second sub-channel 3032. The first sub-channel 3031 is located between the first base 31 and the second base 32, and the second sub-channel 3032 is located in the third base 33. Specifically, the first base 31 and the second base 32 cooperate to form part of the first sub-channel 3031, that is, the two ports of the first sub-channel 3031. One port is located on the first base 31, namely the first interface 202, and the other port is located on the second base 32. The two ports of the first sub-channel 3031 are arranged along the first direction. One of the two ports of the second sub-channel 30 is arranged opposite and sealed to the port on the second base 32, and the other port is arranged along the third direction and sealed to the fourth interface 106 of the refrigerant integrated module 100. The main function of the third base 33 is to change the interface direction of the flow channel 30, which facilitates the fixation with the fourth interface 106 of the refrigerant integrated module 100. To facilitate connection, the multiple third interfaces 302 of the connecting assembly 300 are located at the end of the third base along the third direction, and the multiple fourth interfaces 106 of the refrigerant integrated module 100 are arranged corresponding to the third interfaces 302.In this solution, the refrigerant integrated module 100 is fixedly connected to the connecting assembly 300 by threads. The structure of the threads is the same as that of the above-mentioned embodiment 1 and will not be described in detail here.

[0051] It should be noted that in the above embodiment, the connecting assembly 300 includes a first base 31, a second base 32, and a third base 33. The first base 31, the second base 32, and the third base 33 are separately provided and welded together. The connecting assembly 300 can be made of metal, such as an aluminum alloy. Of course, in other embodiments, the first base 31, the second base 32, and the third base 33 are integrally formed, that is, the connecting assembly 300 is made of plastic and is integrally molded by injection molding. In other embodiments, the second base 32 and the third base 33 are integrally formed.

[0052] In the thermal management modules of Examples 1 and 2 of the present application, the coolant integrated module 200, the connecting assembly 300 and the refrigerant integrated module 100 are arranged in sequence along the first direction, but the present application is not limited to the above-mentioned layout. The coolant integrated module 200 and the refrigerant integrated module 100 can be adjusted separately according to the reserved positions of the entire vehicle. The coolant integrated module 200 and the refrigerant integrated module 100 are connected through the connecting assembly 300. Therefore, the coolant integrated module 200 and the refrigerant integrated module 100 can be designed separately and can be carried out simultaneously without affecting each other. The positions of the first interface 202 and the fourth interface 106 are reserved, and finally the connecting assembly 300 is designed to couple the two. The structure of the connection assembly 300 can be adjusted based on the reserved positions of the first interface 202 and the fourth interface 106. The structure of the present application is more flexible with respect to the layout and installation space of the thermal management module. For example, the reserved positions of the first interface 202 and the fourth interface 106 can be changed based on the reserved space of the entire vehicle, and the second flow channel plate assembly 20 and the first flow channel plate assembly 10 can be respectively arranged on opposite sides of the connection assembly 300, or the second flow channel plate assembly 20 and the first flow channel plate assembly 10 can be respectively arranged on adjacent sides of the connection assembly 300. It can also be understood that the coolant integrated module 200 and the refrigerant integrated module 100 can be arranged along the third direction or the second direction, that is, the coolant integrated module 200 and the refrigerant integrated module 100 can be arranged on opposite sides of the connection assembly 300, or the coolant integrated module 200 and the refrigerant integrated module 100 can be arranged on adjacent sides of the connection assembly 300. The thermal management module of the present application is conducive to the design of standardized modules. For example, as the thermal management module tends more and more towards the secondary circuit, the refrigerant integrated module 100 becomes simpler than the previous system, and the design of the coolant integrated module becomes more and more complicated. In this case, the refrigerant integrated module 100 is designed as a standardized module. Since the refrigerant integrated module 100 and the coolant integrated module 200 do not affect each other, it is only necessary to change the design structure of the coolant integrated module 200 and design the structure of the corresponding connection component 300 according to the requirements to achieve assembly convenience and design and development costs and improve the progress of design and development.

Although this specification has described the present invention in detail with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
