DETAILED DESCRIPTION

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The thermal management module is used to control and maintain the temperature of the system. It is used in many fields such as industry, energy storage, and automobiles. Through the operation of the system, the temperature in the room and the equipment is kept within an appropriate range to ensure the normal operation of the equipment and the comfort of the personnel.

[0036] Taking automobiles as an example, the thermal management module is an important part of the entire vehicle system. Specifically, temperature control is required in multiple locations such as batteries, motors, electric drive systems, and the vehicle's passenger compartment. Effective temperature control ensures that each component of the electric drive system operates in an appropriate temperature environment to avoid damage to components caused by excessively high or low temperatures or affect the working performance of components. The thermal management module can also adjust the temperature of the passenger compartment to improve the comfort of the vehicle during driving.

[0037] The present invention provides a flow channel plate 10, which can be applied to a thermal management module. The flow channel plate 10 has a high degree of integration and a reasonable layout, which can improve the working efficiency and working stability of the thermal management module. It should be noted that the thermal management module of the present invention can be applied to vehicles, energy storage systems or other equipment that requires thermal management control. This application is mainly explained by taking the application of the thermal management module in a vehicle as an example. The thermal management module can achieve temperature control of the vehicle's battery, motor and other electric drive systems as well as the passenger compartment and other locations. The thermal management module of the present application mainly exchanges heat by liquid cooling. It can be understood that the liquid has a large heat capacity and can absorb more heat, which can improve the heat exchange efficiency and heat exchange effect. The liquid heat exchange method has low noise and high stability, which can reduce the failure rate of the thermal management module and improve the working stability of the thermal management module.

[0038] The thermal management module is configured to regulate the temperature of the vehicle's components and spaces. For example, when the vehicle's operating environment temperature is low, the thermal management module can heat the battery, electric drive system, or passenger compartment to prevent the battery temperature from being too low, causing difficulty in starting the car, or affecting the battery's output power, and to maintain the vehicle's driving comfort. When the vehicle's operating environment temperature is too high, the thermal management module can cool the battery, electric drive system, or passenger compartment to remove heat from the components or space, avoid heat accumulation, affect the safety performance of the components, and improve driving comfort.

[0039] Combination Figure 1 According to the flow channel plate 10 of the thermal management module of the embodiment of the present invention, the flow channel plate 10 may have a plurality of flow channels 12, and the flow channels 12 may provide circulation channels for the fluid medium. The plurality of flow channels 12 may be arranged in the flow channel plate 10 and separated from each other. Each flow channel 12 has a first interface 12a and a second interface 12b. By integrating the plurality of flow channels 12 in the flow channel plate 10, the traditional pipeline connection is replaced, and the integration of the flow channel plate 10 is improved, thereby reducing the installation space of the connecting pipelines between the various components of the thermal management module, and improving the compactness of the structure of the thermal management module. The flow channels 12 are arranged in the flow channel plate 10, which can improve the stability of the structure of the flow channels 12. In addition, the temperatures of the fluid medium in the plurality of flow channels 12 may be different. By separating the plurality of flow channels 12 from each other in the flow channel plate 10, the mutual influence between different flow channels 12 is avoided, and the heat loss caused by the heat exchange between different flow channels 12 is reduced.

[0040] Among them, one of the first interface 12a and the second interface 12b can be configured as the inlet of the flow channel 12, and the other can be configured as the outlet of the flow channel 12. And multiple flow channels 12 can be configured to connect components such as low-temperature heat exchangers, high-temperature heat exchangers, motors, batteries, air conditioners, and heaters. It can be understood that different components have different calorific values ​​and working environment temperatures. For different components or different ambient temperatures, fluid media with different temperatures are required to exchange heat with components or spaces, and the temperature of the fluid medium after heat exchange with different components will also be different, so the temperature of the fluid in each flow channel 12 on the flow channel plate 10 will be different.

[0041] In order to further reduce the mutual influence between the multiple flow channels 12 and reduce heat loss, the flow channel plate 10 may have a first area 10a and a second area 10b spaced apart from each other, and the multiple flow channels 12 may include at least one first flow channel 121 and at least one second flow channel 122. The first flow channel 121 may be arranged in the first area 10a, and the second flow channel 122 may be arranged in the second area 10b. By arranging different flow channels 12 in different areas spaced apart from each other, the heat exchange caused by the difference in medium temperature of the fluid in different flow channels 12 can be reduced, thereby reducing the energy consumption of the thermal management module.

[0042] In addition, different flow channels 12 can be arranged in different areas according to the temperature of the fluid medium in the flow channels 12. For example, the flow channels 12 with higher fluid medium temperature can be arranged in the first area 10a, and the flow channels 12 with lower fluid medium temperature can be arranged in the second area 10b, or the flow channels 12 with lower fluid medium temperature can be arranged in the first area 10a, and the flow channels 12 with higher fluid medium temperature can be arranged in the second area 10b. By arranging multiple flow channels 12 in hot and cold zones, heat loss caused by heat exchange between different flow channels 12 can be reduced, and the working efficiency of the thermal management module can be improved. The thermal management module has high heat exchange efficiency and low energy consumption, which helps to improve the vehicle's cruising range.

[0043] The multiple flow channels 12 may include at least one first flow channel 121 and at least one second flow channel 122. In other words, one first flow channel 121 or multiple first flow channels 121 may be arranged in the first area 10a, and one second flow channel 122 or multiple second flow channels 122 may be arranged in the second area 10b. The specific adjustments can be made according to the structure of the thermal management module.

[0044] It should be noted that the plurality of flow channels 12 may include at least one first flow channel 121 and at least one second flow channel 122 , and the plurality of flow channels 12 may further include a third flow channel 123 , a fourth flow channel 124 , and the like.

[0045] The thermal management module may have a water side component, which is configured to perform heat exchange by water cooling. The water side component may include the aforementioned flow channel plate 10, a water kettle, a water valve and at least one heat exchanger, and the water kettle, the water valve and at least one heat exchanger are connected to multiple flow channels 12 to form a water circuit. The water circuit can perform heat exchange with functional components or the passenger compartment inside the vehicle, so that the functional components and the passenger compartment are within a suitable temperature range.

[0046] The water side component may also include a heater. When the ambient temperature is low, the fluid medium in the water circuit may be heated by the heater to heat the battery, the passenger compartment and other locations.

[0047] The flow channel plate 10 can also provide installation points for components of the water side assembly and provide support for the components, thereby improving the integration of the thermal management module. One or more components such as a water pump, a water valve, and a heat exchanger can be installed on the flow channel plate 10. By integrating the components on the flow channel plate 10, the integration of the water side assembly is improved. By reducing the length of the connecting pipes through a reasonable layout, the structure of the thermal management module is made compact, which is conducive to the miniaturization and lightweight design of the thermal management module and can improve the overall structural stability of the thermal management module.

[0048] For example, the first region 10a may be arranged with a plurality of first channels 121, each of which has a first interface 12a and a second interface 12b, wherein the first channel 121 may be configured as a heating liquid channel 121a, the first interface 12a of the first channel 121 may be connected to a heater, and the second interface 12b may be connected to a heat exchanger, and after the fluid medium is heated by the heater, it enters the heat exchanger through the first channel 121 to exchange heat with the components. The heater is configured to heat the fluid medium, and the temperature of the fluid medium flowing through the first channel 121 will be relatively high. By arranging the first channel 121 in the first region 10a, the interference of the first channel 121 with the second channel 122 is reduced, heat loss is avoided, and heat exchange efficiency is improved.

[0049] For another example, the thermal management module may include an air conditioning heat exchange loop, which may be configured to perform heat exchange in the passenger compartment, the first flow channel 121 may be configured as an air conditioning heat exchange flow channel 121b, and the first interface 12a of the first flow channel 121 may be connected to the outlet of the air conditioning heat exchange loop, that is, the liquid after heat exchange in the passenger compartment may enter the first flow channel 121 from the first interface 12a, and the second interface 12b may be connected to the heat exchanger. The air conditioning heat exchange loop may be configured to cool down the passenger compartment, and the fluid medium in the air conditioning heat exchange loop enters the first flow channel 121 after exiting the air conditioner, and the temperature is usually relatively high. By arranging the first flow channel 121 in the first area 10a, the interference with the second flow channel 122 can be reduced, heat loss can be avoided, and the heat exchange efficiency can be improved.

[0050] Furthermore, the first interface 12a of the first flow channel 121 can be located on the side of the first area 10a away from the second area 10b, and the first interface 12a of the first flow channel 121 can be configured as a fluid medium inlet. The temperature of the fluid is relatively high. By setting the first interface 12a on the side away from the second area 10b, the impact on the fluid medium in the flow channel 12 in the second area 10b can be effectively reduced, and the first interface 12a is arranged on the side of the flow channel plate 10, which can facilitate the connection of pipelines. For example, the first interface 12a can be connected to components such as heaters and air conditioners. By setting the first interface 12a on the side of the flow channel plate 10, it is convenient to connect components through the first interface 12a, thereby improving installation efficiency and facilitating subsequent maintenance.

[0051] The second interface 12b of the first flow channel 121 may be located on a side of the first region 10a close to the second region 10b, and the first flow channel 121 is configured to gradually approach the second region 10b from the first interface 12a to the second interface 12b, and is configured to connect to a heat exchanger.

[0052] Specifically, the flow channel 12 of the first area 10a and part of the flow channels 12 of the second area 10b can be connected to the heat exchanger to facilitate heat exchange of the fluid medium in the flow channel 12, and different flow channels 12 can be configured to connect different heat exchangers. Multiple different heat exchangers can be concentrated in one area to form a heat exchange area or heat exchange module, which is convenient for assembly and centralized management of heat exchangers. When the heat exchanger is abnormal, it is also convenient to check the area and facilitate subsequent maintenance. Multiple heat exchangers can be close to the first area 10a and the second area 10b at the same time to facilitate the heat exchanger to connect multiple flow channels 12 of the first area 10a and the second area 10b. The second interface 12b is set on the side of the first area 10a close to the second area 10b, which is convenient for connecting the heat exchanger through the second interface 12b, making the overall structure of the thermal management module more compact and the layout more reasonable.

[0053] Combination Figure 1 In some embodiments of the present invention, at least one first flow channel 121 may be divided into multiple sections separated from each other, and configured to be arranged from the side of the first area 10a away from the second area 10b to the side close to the second area 10b. Among them, the first flow channel 121 may be divided into a first part 1211 and a second part 1212 separated from each other. For example, the first part 1211 may be configured to connect the air conditioning heat exchange circuit with the water valve, and the second part 1212 may be configured to connect the water valve and the heat exchanger. The water valve can provide the circulation system with a flow channel 12 switching function and a flow ratio adjustment function for different flow channels 12. For example, when the heat exchange demand is high, the flow ratio of the fluid medium in the flow channel 12 can be increased by a water valve to improve the efficiency of heat exchange, or different flow channels 12 can be switched by a water valve according to different heat exchange requirements. After coming out of the air conditioner, the fluid medium in the air conditioning heat exchange circuit enters the first flow channel 121 from the first interface 12a and passes through the water valve. For example, when the heat exchange demand is high, the flow ratio of the fluid medium in the second part 1212 can be adjusted by the water valve to improve the heat exchange efficiency of the thermal management device and meet the heat exchange requirements under different ambient temperatures.

[0054] In some embodiments of the present invention, the first area 10a and the second area 10b of the flow channel plate 10 may be connected to water valves to provide flow channel 12 switching and flow ratio adjustment functions for the multiple flow channels 12 in the first area 10a and the second area 10b.

[0055] Among them, a water valve mounting seat 11 is provided on the first area 10a, and a first water valve is installed. The first water valve can be a three-way valve, a four-way valve, a five-way valve, etc. The first water valve can connect at least one first flow channel 121 and a kettle, and the kettle can provide the water circuit with the functions of replenishing fluid, degassing and noise reduction.

[0056] In some embodiments of the present invention, the second region 10b may be provided with a valve mounting seat 11, and the water valve mounting seat 11 may be configured to mount a second water valve, so as to stably fix the second water valve on the flow channel plate 10, and improve the structural strength of the second water valve. The first interface 12a of the second flow channel 122 may be connected to the water valve mounting seat 11, so as to facilitate adjusting the flow rate of the fluid medium in the second flow channel 122 or switching the flow channel 12 of the fluid medium in the second flow channel 122 through the second water valve, thereby meeting different heat exchange requirements. Among them, the second water valve may be a three-way valve, a four-way valve, a five-way valve, etc.

[0057] Further, the second flow channel 122 may include a plurality of second flow channels 122, each of which may have a first interface 12a and a second interface 12b, and one of the first interface 12a and the second interface 12b is configured as a fluid medium inlet, and the other is configured as a fluid medium outlet. The plurality of second flow channels 122 may be arranged around the water valve mounting seat 11, and the second interfaces 12b of a portion of the plurality of second flow channels 122 are located on a side of the second region 10b away from the first region 10a, and are provided on the side of the flow channel plate 10. Figure 1 As shown in the figure, the second flow channel 122 may include multiple flow channels 12, for example, may include a second flow channel 122a, a second flow channel 122b, a second flow channel 122c and a second flow channel 122d, wherein the second interfaces 12b of the three second flow channels 122a, 122b and 122c may be located on the side of the second area 10b away from the first area 10a, and are arranged on the side of the flow channel plate 10.

[0058] For example, the second interface 12b of the second flow channel 122 can be connected to a heat exchange circuit for heat exchange with components such as a motor or a low-temperature radiator. By arranging the second interface 12b on the side of the flow channel plate 10, it is convenient to connect components such as a motor or a low-temperature radiator through the second interface 12b, facilitate the pipeline connection of the thermal management module, improve the installation efficiency, and facilitate subsequent maintenance.

[0059] Among them, the temperature of the fluid medium flowing through the second flow channel 122 is relatively low. By setting the second flow channel 122 in the second area 10b, a large temperature difference between the fluid medium in the first flow channel 121 and the second flow channel 122 is avoided, and heat loss caused by heat exchange between the flow channels 12 is avoided.

[0060] The thermal management module may include a low-temperature radiator circuit, which may be configured to assist in heat exchange for components such as batteries. Figure 1 As shown in , one of the second flow channels 122 can be a low-temperature radiator heat exchange flow channel 122a, and the second interface 12b of the second flow channel 122 can be connected to the inlet of the low-temperature heat exchange circuit, and the second interface 12b is arranged on the side of the flow channel plate 10 to facilitate the connection of the low-temperature radiator.

[0061] Combination Figure 1 As shown in , the second flow channel 122 can also be configured as a low-temperature radiator heat exchange flow channel 122b. The second interface 12b of the second flow channel 122 can be connected to the outlet of the low-temperature heat exchange circuit, and the second interface 12b is arranged on the side of the flow channel plate 10 to facilitate the connection to the low-temperature radiator.

[0062] Combination Figure 1 As shown in , the thermal management module may also include a motor heat exchange circuit, which may be configured to exchange heat for the motor, the first flow channel 121 may be configured as a motor heat exchange flow channel 122c, and the second interface 12b of the second flow channel 122 may be connected to the inlet of the motor heat exchange circuit. By arranging the second interface 12b on the side of the flow channel plate 10, it is convenient for the second flow channel 122 to connect to the motor.

[0063] Combination Figure 1 In some embodiments of the present invention, a hollow area 10c may be formed between the second area 10b and the first area 10a. By providing the hollow area 10c on the flow channel plate 10, the weight of the flow channel plate 10 can be reduced, which is beneficial to the lightweight design of the thermal management module.

[0064] Among them, the water side component may include at least one heat exchanger, and the heat exchangers may be concentrated in the hollow area 10c. The heat exchangers may be concentrated in the hollow area 10c to form a heat exchange zone or a heat exchange module, and the heat exchanger can be close to the first area 10a and the second area 10b at the same time to facilitate the heat exchanger to connect multiple flow channels 12 of the first area 10a and the second area 10b.

[0065] Combination Figure 1 Another part of the multiple second flow channels 122 and the second interface 12b of the first flow channel 121 are located around the hollow area 10c and are configured to connect to the heat exchanger, wherein another part of the second flow channel 122 and the second interface 12b of the first flow channel 121 are configured to connect to the heat exchanger. Such an arrangement can facilitate the connection and installation of pipelines, as well as subsequent maintenance, and makes the layout of the multiple flow channels 12 and the heat exchanger reasonable and compact.

[0066] It should be noted that, combined with Figure 1 The second flow channel 122 may include a plurality of flow channels 12. In combination with the above-mentioned embodiment, a portion of the second flow channel 122, such as the second interface 12b of 122a, 122b, and 122c, is located on a side of the second region 10b away from the first region 10a and is disposed on a side of the flow channel plate 10. Another portion of the second flow channel 122, such as 122d, may be located around the hollow region 10c and configured to connect to a heat exchanger.

[0067] In some embodiments of the present invention, the plurality of flow channels 12 may further include a third flow channel 123, wherein the first interface 12a of the third flow channel 123 is close to the second water valve mounting seat 11, and the second interface 12b of the third flow channel 123 is far away from the second water valve mounting seat 11 and is located around the hollow area 10c, and is configured to connect to a heat exchanger. Specifically, the third flow channel 123 may be connected to the second water valve and the heat exchanger, so as to facilitate adjusting the flow rate of the fluid medium in the third flow channel 123 or switching the flow channel 12 of the fluid medium in the third flow channel 123 through the second water valve, thereby meeting different heat exchange requirements.

[0068] Specifically, a kettle may be installed in the second area 10b, and the kettle may provide the functions of replenishing, degassing, and reducing noise for the water circuit. The kettle may be connected to the second water valve and the third flow channel 123. For example, when the heat exchange demand is large, the flow rate of the fluid medium in the flow channel 12 may be adjusted by the water valve, and the kettle may provide the function of replenishing the water circuit. By increasing the flow rate of the fluid medium in the flow channel 12, the heat exchange amount may be increased, thereby meeting the heat exchange demand under different environments.

[0069] In some embodiments of the present invention, the plurality of flow channels 12 may further include a fourth flow channel 124, a portion of the fourth flow channel 124 is located in the first area 10a, and another portion is located in the second area 10b. For example, the fourth flow channel 124 may be connected to the battery heat exchange circuit, the fourth flow channel 124 may be configured as a battery outlet flow channel 12, the first interface 12a of the fourth flow channel 124 may be connected to the outlet of the battery heat exchange circuit, and the second interface 12b may be connected to the water valve of the second area 10b, that is, the fluid medium after heat exchange with the battery enters the fourth flow channel 124 from the first interface 12a of the fourth flow channel 124, and then enters the heat exchanger for heat exchange. It can be understood that the temperature of the battery is usually high, so the temperature of the fluid medium entering the fourth flow channel 124 from the battery heat exchange circuit is relatively high, a portion of the fourth flow channel 124 is located in the first area 10a, and another portion is located in the second area 10b, and may be located at the edge of the flow channel plate 10, which can reduce interference with the flow channels 12 in the first area 10a and the second area 10b. In addition, the length of the flow channel 12 of the fourth flow channel 124 is relatively long, and the fluid medium can dissipate part of the heat during the flow of the flow channel 12 .

[0070] In some embodiments of the present invention, the flow channel plate 10 is configured so that the temperature of the fluid passing through the first flow channel 121 is higher than the temperature of the fluid passing through the second flow channel 122. The first flow channel 121 may be provided in the first region 10a, and the second flow channel 122 may be provided in the second region 10b. In other words, the first region 10a may be a high-temperature flow channel region, and the second region 10b may be a low-temperature flow channel region. According to the different temperatures of the fluid medium in different flow channels 12, the flow channels 12 are arranged in different regions to avoid heat exchange between the fluid medium in the first flow channel 121 and the second flow channel 122, resulting in heat loss. By zoning, the heat exchange efficiency of the thermal management device is improved and energy consumption is reduced.

[0071] In some embodiments of the present invention, multiple flow channels 12 are arranged flatly in the flow channel plate 10 to construct a single-layer flow channel 12 structure in the flow channel plate 10, and the multiple flow channels 12 are spaced apart in the flow channel plate 10, which can effectively avoid interference between different flow channels 12 and avoid heat exchange between the multiple flow channels 12, resulting in heat loss.

[0072] Combination Figures 2 to 4 In some embodiments of the present invention, the flow area of ​​at least one flow channel 12 in the extension direction is substantially the same. It can be understood that multiple flow channels 12 are arranged on the flow channel plate 10. In order to maximize the structural compactness of the flow channel plate 10 and reduce the length of the flow channel 12, there may be a situation where the flow channel 12 turns or avoids. By keeping the flow area of ​​the flow channel 12 in the extension direction basically unchanged, it is avoided that when the shape or structure of the flow channel 12 changes, the flow velocity of the fluid changes, thereby affecting the flow resistance.

[0073] Wherein, at least one liquid flow channel 12 may have a first section 125 and a second section 126. By setting the first section 125 and the second section 126, the width of the first section 125 in the first direction is smaller than the width of the second section 126, and the height of the first section 125 in the second direction is greater than the height of the second section 126, and the first direction is perpendicular to the second direction. Figure 3 and Figure 4 The first direction refers to the CC direction in the figure, and the second direction refers to the DD direction in the figure. The width dimension of the first segment 125 in the first direction is d1, the width dimension of the second segment 126 in the first direction is d2, the height dimension of the first segment 125 in the second direction is d3, and the height dimension of the second segment 126 in the second direction is d4.

[0074] Specifically, by setting the liquid flow channel 12 into a first section 125 and a second section 126, it is convenient to improve the structural compactness of the flow channel plate 10 and maximize the use of the space of the flow channel plate 10. At the intersection of the first section 125 and the second section 126, the width of the flow channel 12 is relatively small, which can play the effect of avoiding accessory components. By increasing the height of the flow channel 12, the flow area of ​​the flow channel 12 at this position is basically consistent with the area of ​​the normal flow channel 12, ensuring that the flow velocity of the fluid will not change, so as to achieve the best fluid transmission effect, avoid the insufficient width of the flow channel 12 causing the fluid flow velocity to decrease and the flow resistance to increase, and adjust the structure of the flow channel 12 according to the changes in the flow channel 12 to reduce the flow resistance of the liquid, improve the heat exchange efficiency of the thermal management module, and reduce energy consumption.

[0075] According to the water side assembly of the embodiment of the present invention, the water side assembly may include the aforementioned flow channel plate 10, at least one kettle, at least one water valve, and at least one heat exchanger. The kettle, the water valve, and the heat exchanger are connected to the flow channel plate 10 and communicated with a plurality of flow channels 12. Among them, the water valve can provide the flow channel 12 switching function and the flow ratio adjustment function of different flow channels 12 for the circulation system of the flow channel 12. The number of water valves can be one, two, three, etc.; the kettle can provide the circulation system of the flow channel 12 with the functions of fluid replenishment, degassing, and noise reduction. The number of kettles can be adjusted according to the number of heat exchange circuits. One or two kettles can be set. The flow channel plate 10 provides a plurality of series and parallel flow channels 12 for the heat exchange module, replacing the traditional pipe connection, and providing installation points for other parts.

[0076] The kettle may include a first kettle and a second kettle, the first kettle may be arranged in the first area 10a and connected to the first flow channel 121, and the second kettle may be arranged in the second area 10b and connected to the second flow channel 122. The temperature of the fluid medium in the first flow channel 121 and the second flow channel 122 is different. By arranging the first flow channel 121 and the second flow channel 122 in different areas, and providing kettles in different areas, the functions of replenishing, degassing or reducing noise are provided for different flow channels 12, respectively, to further ensure that the flow channels 12 in different areas do not interfere with each other, reduce the heat loss caused by heat exchange between different flow channels 12, and reduce the energy consumption of the thermal management device.

[0077] In some embodiments of the present invention, the kettle may include a first kettle and a second kettle, and a heat insulation layer may be provided between the first kettle and the second kettle. Specifically, the first kettle may be configured to connect the flow channel 12 of the high-temperature flow channel area, and the second kettle may be configured to connect the flow channel 12 of the low-temperature flow channel area. The temperature of the fluid medium in the first kettle and the second kettle may be different. By providing a heat insulation layer, heat exchange between the first kettle and the second kettle is avoided, resulting in heat loss, thereby improving the heat exchange efficiency of the thermal management device.

[0078] In some embodiments of the present invention, a storage cavity and a channel may be provided in the kettle, the channel and the storage cavity are separated and connected to each other, and the channel is connected to a plurality of flow channels 12. The storage cavity may be used to contain fluid, and the channel may include one or more channels, which are connected to the flow channels 12, so as to provide liquid replenishment or degassing to the water circuit through the kettle, so that the water system can operate stably.

[0079] The present invention also provides a thermal management module, including the aforementioned water-side component and refrigerant-side component, the refrigerant-side component is connected to the water-side component and cooperates in heat exchange. The refrigerant-side component may have a refrigerant circuit, and the water-side component may have a water circuit, and the refrigerant-side circuit is connected to the water circuit for heat exchange, so that the temperature control of the vehicle can be achieved. For example, the water circuit can transfer heat with the functional components inside the vehicle so that the functional components are within a suitable temperature range, and then the water in the water circuit can transfer heat with the refrigerant in the refrigerant circuit, so that the water in the water circuit can be restored to its original temperature and continue to transfer heat with the functional components, thereby achieving the temperature control of the vehicle.

[0080] By disposing the aforementioned flow channel plate 10, the thermal management module can reduce heat loss in the thermal management module, thereby lowering energy, and thus improving the working efficiency of the thermal management module.

[0081] The present invention also provides a vehicle, comprising a vehicle body and the aforementioned thermal management module, wherein the thermal management module is mounted on the vehicle body.
