[0018] The second flow channel is parallel to at least one of the two second sidewalls that are arranged opposite each other along the second direction.

[0019] In some embodiments, P of the M first flow channels are straight flow channels, where P ≤ M.

[0020] In some embodiments, the first flow channel includes at least two straight flow channels, and the at least two straight flow channels have an intersection, the intersection being a circular arc transition.

[0021] In some embodiments, the body has a first surface perpendicular to the first direction, and the first surface is provided with a flow channel groove;

[0022] The flow channel structure further includes a connecting plate, which is disposed on the side of the body near the first surface. The connecting plate and the flow channel groove enclose each other to form the first layer of flow channel.

[0023] In some embodiments, the flow channel includes a channel wall that protrudes from the first surface along the first direction;

Furthermore, the function of the first layer of flow channels is to connect different second flow channels. Compared to the case where one first flow channel connects all second flow channels, when multiple first flow channels are provided, and one first flow channel is connected to at least two second flow channels, the structure of the first layer of flow channels can be simplified, which is beneficial for reducing the processing difficulty of the flow channel structure. More importantly, since L of the second flow channels are straight flow channels, and L≤N, meaning at least some of the second flow channels are straight flow channels, at least one of the distance or resistance of the fluid flowing within the straight second flow channels can be reduced, thereby reducing the fluid flow resistance and improving the thermal management efficiency of the vehicle.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0061] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this disclosure.

[0062] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the meaning of the above terms in this disclosure based on the examples provided.

[0063] Currently, in order to improve the integration of the thermal management module, more flow channels need to be set in the flow channel structure, which increases the complexity of the flow channels in the flow channel structure. This may lead to an increase in the flow resistance of the fluid in the flow channel and affect the thermal management efficiency.

[0064] To address the aforementioned problems, some embodiments of this disclosure provide a flow channel structure. The flow channel structures of some embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0065] Figure 1 is a structural diagram of a flow channel structure according to some embodiments. Figures 2 to 5 are structural diagrams of the body according to some embodiments. Figures 6 to 8 are cross-sectional views along line AA in Figure 4, along line BB in Figure 6, and along line CC in Figure 6, respectively, according to some embodiments.

[0066] As shown in Figures 1, 4, and 9, some embodiments of this disclosure provide a flow channel structure 100, including: a body 1, a first layer flow channel 2, and a second layer flow channel 3; the first layer flow channel 2 and the second layer flow channel 3 are spaced apart on the body 1 along a first direction X; the first layer flow channel 2 includes M independent first flow channels 20; the second layer flow channel 3 includes N independent second flow channels 30, of which L are straight flow channels, where L≤N; in some embodiments, one of the M first flow channels 20 is connected to at least two of the N second flow channels 30 to allow fluid to flow between the first layer flow channel 2 and the second layer flow channel 3.

[0067] In some embodiments of this disclosure, since a first layer of flow channels 2 and a second layer of flow channels 3 are provided, and the first layer of flow channels 2 includes M independent first flow channels 20, and the second layer of flow channels 3 includes N independent second flow channels, more flow channels can be provided within the body 1, which is beneficial to improving the flexibility and integration of the flow channel structure. Furthermore, the function of the first layer of flow channels 2 is to connect different second flow channels. Compared to the case where one first flow channel connects all second flow channels, when multiple first flow channels are provided, and one of the multiple first flow channels is connected to at least two of the multiple second flow channels, the structure of the first layer of flow channels 2 can be simplified, which is beneficial to reducing the processing difficulty of the flow channel structure.

[0068] More importantly, since L of the M second flow channels are straight flow channels, and L≤N, meaning that at least some of the second flow channels are straight flow channels, it can reduce at least one of the flow distance or resistance of the fluid in the straight second flow channels, thereby reducing the flow resistance of the fluid in the entire flow path and improving the thermal management efficiency of the vehicle.

[0069] It should be noted that a straight flow channel refers to a structure in which fluid can flow in a straight line within the channel. Furthermore, the first direction X refers to the thickness direction of the body 1, i.e., the vertical direction, and the second direction Y refers to the length or width direction of the body 1, i.e., the horizontal direction. Here, the first direction X is perpendicular to the second direction Y.

[0070] Furthermore, since the first flow channel in some embodiments of this disclosure is used to connect different second flow channels, thereby enabling different operating modes of the thermal management module, the number of first flow channels is typically less than the number of second flow channels.

[0071] In some embodiments, as shown in Figures 2 and 3, the first flow channel has six channels and the second flow channel has three channels. Here, the length and shape of the second flow channel depend on the position and spacing of the control valve, sensor, etc.

[0072] In practical applications, multiple mounting portions 12 are provided around the body 1. The mounting portions 12 are fixedly installed to the vehicle bracket with screws to achieve reliable fixation of the flow channel structure. In some embodiments, a shock-absorbing pad is also provided between the mounting portion 12 and the vehicle bracket to achieve shock absorption and prevent damage to the flow channel structure.

[0073] In some embodiments of this disclosure, the body 1 includes two first sidewalls 18 extending along a second direction Y, the second direction Y being perpendicular to the first direction X; the body 1 is also provided with a plurality of connection ports 4 (as shown in FIG14), the plurality of connection ports 4 being disposed on the first sidewalls 18, and one of the plurality of connection ports 4 communicating with a first flow channel or a second flow channel.

[0074] As shown in Figures 3 and 5, both the first and second flow channels extend horizontally. When the connection port 4 is located on the first side wall 18, the fluid can enter the first or second flow channel horizontally through the connection port 4 without much change or even any change in the flow direction, thereby reducing the flow resistance of the fluid.

[0075] It should be noted that the multiple connection ports 4 can be centrally located on one first sidewall 18 or distributed across two first sidewalls 18. No limitation is made here, and those skilled in the art can adjust them according to actual needs. It is understood that when the multiple connection ports 4 are spaced apart along the second direction Y on one of the two first sidewalls 18, not only can the connection ports 4 be arranged more compactly, which is beneficial for miniaturization of the flow channel structure, but the processing difficulty of the flow channel structure can also be further reduced.

[0076] In some embodiments, a plurality of connection ports 4 are connected to N second channels. Each connection port 4 has a first center line, and the second channels connected to the connection ports 4 have a second center line. The second center line is collinear with the first center line.

[0077] In some embodiments of this disclosure, since the connection port 4 is connected to the second flow channel, i.e., the connection port 4 is concentrated in the second layer flow channel 3, the processing difficulty of the flow channel structure can be further reduced. In addition, since the first center line of the connection port 4 is collinear with the second center line of the second flow channel, the flow direction of the fluid entering the second flow channel through the connection port 4 does not change, thereby further reducing the flow resistance of the fluid.

[0078] In some embodiments, as shown in Figures 4 and 5, the second flow channel includes second flow channels A31, B32, C33, D34, E35, and F36, which are sequentially spaced along the second direction Y. Here, second flow channel A31 is connected to first flow channels A21 and B22, second flow channel B32 is connected to first flow channel A21, second flow channel C33 is connected to first flow channels A21 and B22, and second flow channels D34, E35, and F36 are all connected to first flow channel C23.

[0079] In addition, the connection port 4 includes a first connection port 41, a second connection port 42, a third connection port 43, a fourth connection port 44, a fifth connection port 45, and a sixth connection port 46 arranged sequentially at intervals along the second direction Y. Here, the first connection port 41 is connected to the second flow channel A31, the second connection port 42 is connected to the second flow channel B32, the third connection port 43 is connected to the second flow channel C33, the fourth connection port 44 is connected to the second flow channel D34, the fifth connection port 45 is connected to the second flow channel E35, and the sixth connection port 46 is connected to the second flow channel F36. The above-mentioned connection ports 4 can be used to connect heat exchange components such as the condenser 83, the evaporator 82, the gas separator 85, and the compressor 81.

[0080] In some embodiments, the connection port 4 and the second flow channel satisfy at least one of the following: the connection port 4 has a first center line that is perpendicular to the first sidewall 18; or, the second flow channel has a second center line that is perpendicular to the first sidewall 18.

[0081] In practical applications, the body 1 is roughly rectangular. The plane containing the first sidewall 18 of the body 1 is parallel to the first direction X. When at least one of the following conditions is met: the first center line of the connection port 4 is perpendicular to the first sidewall 18, or the second center line of the second flow channel is perpendicular to the first sidewall 18, the processing difficulty of the flow channel structure can be further reduced.

[0082] In some embodiments of this disclosure, any two of the N second flow channels are arranged in parallel. This simplifies the structure of the second layer flow channel 3 and helps to reduce the processing difficulty of the flow channel structure.

[0083] In some embodiments, the body 1 includes two second sidewalls 19 disposed opposite each other along a second direction Y, the second direction Y being perpendicular to the first direction X; the second flow channel is parallel to at least one of the two second sidewalls 19 disposed opposite each other along the second direction Y. It is understood that the two second sidewalls 19 are located between the two first sidewalls 18, and together with the two first sidewalls 18, form the sidewalls of the body 1.

[0084] In practical applications, the body 1 is roughly rectangular. The second sidewall 19 of the body 1 is parallel to the first direction X. When the second flow channel is parallel to at least one second sidewall 19, the processing difficulty of the flow channel structure can be further reduced.

[0085] In some embodiments of this disclosure, as shown in Figures 3 and 5, the P first flow channels are straight flow channels, where P ≤ M. This allows for a shorter flow channel length per individual first flow channel, meaning the fluid travels a shorter distance within the first flow channel, thereby further reducing flow resistance.

[0086] It should be noted that a straight flow channel refers to a structure in which fluid can flow in a straight direction within the flow channel. In some embodiments, as shown in Figures 3 and 5, the first flow channel A21 and the second flow channel B32 in the first layer flow channel 2, as well as the six second flow channels in the second layer flow channel 3, are all straight flow channels, which can reduce the fluid flow resistance of the flow channel structure and help improve the thermal management efficiency of the vehicle.

[0087] In some embodiments of this disclosure, as shown in FIG3, the M first flow channels include at least two straight flow channels, and the at least two straight flow channels have an intersection with a rounded transition at the intersection. Thus, when at least two straight flow channels intersect, by setting the intersection with a rounded transition, i.e., the corner of the intersection is smoother, the fluid can be guided to flow more smoothly, which helps maintain fluid stability, reduces unnecessary energy loss, and further reduces fluid flow resistance.

[0088] It should be noted that some embodiments of this disclosure do not limit the number of intersecting straight flow channels, and those skilled in the art can make adjustments according to actual needs.

[0089] In some embodiments, as shown in FIG3, the first flow channel C23 of the first layer flow channel 2 includes three intersecting straight flow channels. In addition, in order to further reduce the flow resistance of the fluid passing through the first flow channel C23, the two straight flow channels near the edge of the body 1 are distributed at an obtuse angle, that is, the angle between the centerlines of the two straight flow channels is greater than 90°, which can reduce the local loss of the fluid passing through the intersection and help reduce the fluid flow resistance.

[0090] In some embodiments of this disclosure, the body 1 has a first surface 11 perpendicular to the first direction X, and the first surface 11 is provided with a flow channel groove; the flow channel structure also includes a connecting plate 6, which is disposed on the side of the body 1 close to the first surface 11, and the connecting plate 6 and the flow channel groove enclose each other to form a first layer of flow channel 2.

[0091] In some embodiments of this disclosure, a flow channel groove is provided on the first surface 11 of the body 1, and a connecting plate 6 is provided on the side of the body 1 close to the first surface 11. In this way, the connecting plate 6 and the flow channel groove can be enclosed to form a first layer of flow channel 2. Compared with providing the first layer of flow channel 2 inside the body 1, the structure of the first layer of flow channel 2 is simple, easy to process, and helps to reduce the processing difficulty of the flow channel structure.

[0092] It should be noted that the second layer flow channel 3 located inside the body 1 can be processed and formed by at least one of the machining process or the forging process, and the flow channel groove located on the surface of the body 1 can be formed by the forging process.

[0093] In some embodiments of this disclosure, the flow channel includes a channel wall that protrudes from the first surface 11 along a first direction X; the side of the channel wall facing away from the first surface 11 is connected to the connecting plate 6.

[0094] In some embodiments of this disclosure, since the groove wall protrudes from the first surface 11 along the first direction X, the groove walls of two adjacent flow channel grooves can be spaced apart, thereby isolating the two adjacent flow channel grooves from each other and effectively preventing heat transfer between different modes of the thermal management module. Furthermore, the thickness of the body 1 along the first direction X can be reduced, which is beneficial for the lightweighting of the flow channel structure.

[0095] It should be noted that, in order for the flow channel to meet the burst strength requirements, the thickness of the channel wall should be greater than or equal to 4 mm.

[0096] In some embodiments of this disclosure, the connecting plate 6 is provided with a communication port 60, which is positioned opposite at least a portion of the flow channel groove. The communication port 60 is used to connect a heat exchange component. Thus, by providing the communication port, fluid can flow between the flow channel groove and the heat exchange component, thereby achieving heat exchange.

[0097] In some embodiments, the connection port 60 includes a first connection port 61 and a second connection port 62. Here, the first connection port 61 corresponds to the position of the flow channel groove that encloses the first flow channel B22, and the second connection port 62 corresponds to the position of the flow channel groove that encloses the first flow channel C23, so that the first flow channel B22 and the first flow channel C23 are respectively connected to the heat exchange equipment, thereby realizing different working modes of the thermal management module.

[0098] In some embodiments, as shown in FIG9, the heat exchange component connected to the communication port 60 is a heat exchanger 7, which combines the functions of a plate heat exchanger 7 and a water-cooled condenser 83 (as shown in FIG12). The heat exchanger 7 includes a first air pipe 71 and a second air pipe 72 connected to the flow channel structure, and a first water pipe 73 and a second water pipe 74 connected to an external water supply device (such as the water tank of an engine cooling system).

[0099] In some embodiments, the first air pipe 71 is connected to the first connecting port 61, and the second air pipe 72 is connected to the second connecting port 62. In air conditioning cooling and battery cooling modes, the heat exchanger 7 acts as a water-cooled condenser 83, exchanging heat with the external water supply equipment; in air conditioning heating and battery heating modes, the heat exchanger 7 acts as a plate heat exchanger 7, exchanging heat with the external water supply equipment. This heat exchanger 7 can be a product from related technologies, which can simplify the structure of the thermal management module, reduce the number of channels in the flow channel structure, and avoid system pressure and heat loss.

[0100] In practical applications, the first surface 11 is provided with a plurality of connecting parts 13, and the flow channel structure is connected to the heat exchange component through the connecting parts 13. In some embodiments, the connecting part 13 is a threaded sleeve, and the reliable connection between the flow channel structure and the heat exchange component, i.e., the heat exchanger 7, is achieved by connecting the bolts to the threaded sleeve.

[0101] In some embodiments of this disclosure, the first surface 11 is provided with one of a positioning protrusion 63 (as shown in FIG1) and a positioning recess 111; the connecting plate 6 is provided with the other of the positioning protrusion 63 or the positioning recess 111 on the side near the first surface 11, and the positioning protrusion 63 is embedded in the positioning recess 111.

[0102] In some embodiments of this disclosure, the positioning protrusion 63 and positioning recess 111 are provided. By embedding the positioning protrusion 63 into the positioning recess 111, on the one hand, the connecting plate 6 can be positioned, avoiding leakage in the flow channel structure due to incorrect installation during the assembly of the body 1 and the connecting plate 6. On the other hand, the requirements for tooling fixtures can be reduced during the assembly of the body 1 and the connecting plate 6, which is beneficial to reducing production line costs.

[0103] It should be noted that in some embodiments of this disclosure, the positioning protrusions 63 and positioning recesses 111 should have the same number and be positioned relative to each other. In some embodiments, two positioning protrusions 63 and two positioning recesses 111 are provided, with one positioning protrusion 63 corresponding to one positioning recess 111. Furthermore, the accompanying drawings in some embodiments of this disclosure only show the case where the positioning recess 111 is provided on the first surface 11 and the positioning protrusion 63 is provided on the connecting plate 6. In practical applications, those skilled in the art can also provide the positioning recess 111 on the connecting plate 6 and the positioning protrusion 63 on the first surface 11. This is not limited here, and those skilled in the art can adjust it according to actual needs.

[0104] In some embodiments, the connecting plate 6 and the body 1 are connected by furnace welding.

[0105] In some embodiments of this disclosure, the body 1 has a second surface 17 perpendicular to the first direction X; as shown in FIG14, the body 1 is also provided with a plurality of mounting holes 5, which are disposed on the second surface 17 and communicate with the second layer flow channel 3. The mounting holes 5 are used to install control valves. In this way, since the mounting holes 5 are connected to the second layer flow channel 3, by setting the control valve in the mounting holes 5, the flow direction and flow rate of fluid between the second layer flow channel 3 and the first layer flow channel 2 can be controlled to realize different working modes of the thermal management module.

[0106] It should be noted that the second surface 17 and the first surface 11 are two surfaces of the body 1 that are arranged opposite to each other along the first direction X. In some embodiments, the control valve includes a solenoid valve (SOV), an electronic expansion valve (EXV), etc., and correspondingly, the mounting hole 5 includes a solenoid valve mounting hole, an electronic expansion valve mounting hole, etc.

[0107] In some embodiments, as shown in Figures 2 and 7, the solenoid valve mounting holes include a first solenoid valve mounting hole 511, a second solenoid valve mounting hole 512, a third solenoid valve mounting hole 513, and a fourth solenoid valve mounting hole 514; the electronic expansion valve mounting holes include a first electronic expansion valve mounting hole 521, a second electronic expansion valve mounting hole 522, a third electronic expansion valve mounting hole 523, and a fourth electronic expansion valve mounting hole 524. Furthermore, the thermal management module typically includes various sensors to detect parameters such as fluid temperature and pressure. In some embodiments, the sensors include a first temperature sensor T1, a second temperature sensor T2, a third temperature sensor T3, a pressure sensor P1, and a pressure-temperature sensor PT1. Correspondingly, the mounting holes 5 also include a first temperature sensor mounting hole 531, a second temperature sensor mounting hole 532, a third temperature sensor mounting hole 533, a pressure sensor mounting hole 541, and a pressure-temperature sensor mounting hole 551.

[0108] It should be noted that some embodiments of this disclosure do not specifically limit the location of the mounting hole 5 for installing various control valves. Those skilled in the art can make corresponding adjustments according to the overall layout of different vehicles and the layout of each heat exchange component in the thermal management module, so as to meet the thermal management needs of vehicles under different operating conditions.

[0109] In some embodiments of this disclosure, a second flow channel communicates with at least one mounting hole 5; the second flow channel has a second center line, and the mounting hole 5 has a third center line, which is perpendicular to the second center line. Thus, during processing, the mounting hole 5 can be machined from top to bottom along the first direction X to ensure communication between the mounting hole 5 and the second flow channel, which helps reduce the processing difficulty of the mounting hole 5.

[0110] As shown in Figure 2, the connection ports 4 are centrally located in the second layer flow channel 3 and are used to connect to the heat exchange components. Based on this, in some embodiments of this disclosure, the first direction X is vertical, and the second layer flow channel 3 is adapted to be located above the first layer flow channel 2. Thus, by placing the second layer flow channel 3 above the first layer flow channel 2, fluid entering the second layer flow channel 3 from the heat exchange components via the connection ports 4 can flow towards the first layer flow channel 2 by gravity, saving energy and reducing the operating cost of the thermal management module. In some embodiments of this disclosure, the body 1 also has a hollow area 14, which is located between at least one of two adjacent first flow channels or between two adjacent second flow channels.

[0111] In some embodiments of this disclosure, since at least one of the two adjacent first channels or the two adjacent second channels is provided with a hollow area 14, on the one hand, heat exchange between the thermal management modules in different modes can be avoided; on the other hand, the fluid structure can be made lighter.

[0112] In summary, the flow channel structure provided by some embodiments of this disclosure has at least the following advantages:

[0113] In some embodiments of this disclosure, by providing a first layer of flow channels and a second layer of flow channels, with the first layer comprising M independent first flow channels and the second layer comprising N independent second flow channels, more flow channels can be provided within the main body 1, which is beneficial for improving the flexibility and integration of the flow channel structure. Furthermore, the function of the first layer of flow channels is to connect different second flow channels. Compared to providing one first flow channel connecting all second flow channels, providing multiple first flow channels, with each first flow channel connected to at least two second flow channels, simplifies the structure of the first layer of flow channels and reduces the processing difficulty of the flow channel structure. More importantly, since L of the second flow channels are straight-line flow channels (L≤N), meaning at least some of the second flow channels are straight-line flow channels, the distance the fluid travels within the second flow channels can be reduced, thereby reducing fluid resistance and improving the thermal management efficiency of the vehicle.

[0114] Figures 9 to 11 are structural diagrams of a thermal management module according to some embodiments, Figure 12 is a working principle diagram of a thermal management module according to some embodiments, and Figures 13 to 14 are structural diagrams of another thermal management module according to some embodiments.

[0115] As shown in Figures 9 to 11, some embodiments of this disclosure also provide a thermal management module 901, including: a flow channel structure 100 of any of the above embodiments and a control valve, wherein the control valve is installed in the flow channel structure 100.

[0116] It should be noted that in some embodiments of this disclosure, the structure of the flow channel structure 100 is the same as that of the flow channel structure in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.

[0117] As shown in Figures 13 and 14, this embodiment also provides another thermal management module. Compared to the thermal management modules shown in Figures 9 to 11, the module's base size and shape, the arrangement of components (including heat exchange components, control valves, sensors, etc.), and the connection ports on the body 1 have been changed. Correspondingly, the arrangement of the first layer flow channel 2 and the second layer flow channel 3 within the flow channel structure has also been changed accordingly. Therefore, on the one hand, different vehicle models can be adapted to different spatial arrangement requirements by changing the boundary information such as the size and shape of the thermal management module. On the other hand, different components can be integrated, and the structures of the first layer flow channel 2 and the second layer flow channel 3 can be adjusted to match different operating modes of the vehicle's thermal management module. Furthermore, the structural arrangement can be optimized by changing the positions of the components.

[0118] Furthermore, as shown in Figure 14, when the flow channel structure is formed by machining, there may be excess machining holes 15 on the body 1. After machining, a plug 16 is needed to seal the machining holes 15 to improve the sealing performance between the plug 16 and the machining holes 15 and prevent fluid leakage. In some embodiments, the plug 16 and the machining holes 15 can be welded together.

[0119] In some embodiments of this disclosure, the control valve includes at least one of a solenoid valve or an electronic expansion valve. Here, the solenoid valve can control the flow of fluid in the flow channel to realize the normal operation of the thermal management module; the electronic expansion valve can throttle and reduce pressure, regulate flow rate and control superheat, and is the control core of the vehicle's thermal management module. The electronic expansion valve sends a drive signal to the motor through the controller, and the transmission system converts the rotational motion of the motor into linear motion, thereby driving the valve needle to move up and down to realize the change of valve opening, thereby regulating the flow rate of the fluid.

[0120] In some embodiments, control valves are installed in the second flow channel, and the control valves installed in the same second flow channel are of the same type. Generally, control valves of the same type require roughly the same installation space, such as the opening size of the mounting hole 5. By installing control valves of the same type in the same second flow channel, not only can the installation of the control valves be more compact, which helps to reduce the volume of the flow channel structure, but the structure of the flow channel structure can also be simplified, which helps to reduce the processing difficulty of the flow channel structure. In some embodiments, as shown in FIG2, two control valves are installed in both second flow channels A31 and second flow channels C33, and both control valves are solenoid valves.

[0121] In some embodiments, as shown in FIG10, the solenoid valves include a first solenoid valve SOV1, a second solenoid valve SOV2, a third solenoid valve SOV3, and a fourth solenoid valve SOV4, and the electronic expansion valves include a first electronic expansion valve EXV1, a second electronic expansion valve EXV2, a third electronic expansion valve EXV3, and a fourth electronic expansion valve EXV4. Different modes of the thermal management module can be switched by opening and closing different solenoid valves and electronic expansion valves. Referring to FIG12, the following provides a detailed description of eight modes of the thermal management module in some embodiments of this disclosure.

[0122] In this embodiment, the heat exchange components include a compressor 81, an evaporator 82, a condenser 83, a heat exchanger 7, a battery pack direct cooling plate 84, and a gas separator 85. Here, the outlet of the compressor 81 is connected to the first connection port 41, the inlet of the evaporator 82 is connected to the fifth connection port 45, the outlet of the condenser 83 is connected to the fourth connection port 44, the inlet and outlet of the battery pack direct cooling plate 84 are connected to the second connection port 42 and the sixth connection port 46, respectively, and the inlet of the gas separator 85 is connected to the third connection port 43. The heat exchanger 7 includes a first gas pipe 71 and a second gas pipe 72 connected to the flow channel structure, and a first water pipe 73 and a second water pipe 74 connected to an external water supply device (such as the water tank of an engine cooling system).
