Description

Technical Field

[0001] This application relates to the field of thermal management technology, specifically to a thermal management integrated module, a thermal management system, and a vehicle. Background Technology

[0002] In the thermal management system of new energy vehicles, there are multiple circulation loops, such as battery cooling circulation loop, electric drive cooling circulation loop, and passenger compartment cooling loop. In traditional thermal management systems, each circulation loop is set up independently, which has problems such as a large number of components, complex pipeline connection and layout, low energy utilization and large space occupation.

[0003] Existing technologies propose integrating multiple components onto an antifreeze flow channel plate to achieve heat exchange between the antifreeze circuit and the refrigerant circuit, thereby improving energy utilization and reducing space occupancy. Specifically, the antifreeze circuit and the refrigerant circuit exchange energy through heat exchange pipes installed inside the power battery cooler.

[0004] However, when moisture and impurities are present in the refrigerant, it will significantly affect its heat exchange process in the power battery cooler, leading to decreased heat exchange efficiency, reduced system reliability, and even damage to components. Utility Model Content

[0005] One objective of this application is to provide a thermal management integrated module to solve the technical problem that the presence of moisture and impurities in the refrigerant in the thermal management integrated module of the prior art can easily affect its heat exchange efficiency in the power battery cooler; another objective is to provide a thermal management system; and a third objective is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A thermal management integrated module, comprising: A flow channel plate assembly having a first side and a second side facing away from each other, the flow channel plate assembly having an antifreeze flow channel inside, and the first side of the flow channel plate assembly having a plurality of external pipe interfaces communicating with the antifreeze flow channel; A power battery cooler is integrated on the second side of the flow channel plate assembly. The interior of the power battery cooler includes a first heat exchange pipe and a second heat exchange pipe. The first heat exchange pipe is connected to the antifreeze flow channel of the flow channel plate assembly. A drying bottle is integrated on the second side of the flow channel plate assembly. A one-way valve is provided at the refrigerant inlet of the drying bottle, and the refrigerant outlet of the drying bottle is connected to the refrigerant inlet of the second heat exchange pipeline.

[0007] Based on the aforementioned technical means, since the refrigerant outlet of the dryer bottle is connected to the refrigerant inlet of the second heat exchange pipeline of the power battery cooler, the refrigerant can pass through the dryer bottle to remove moisture and impurities before entering the interior of the power battery cooler for heat exchange. Before the refrigerant enters the power battery cooler, the dryer bottle can effectively remove moisture from the refrigerant, preventing moisture from freezing and clogging or corroding the second heat exchange pipeline in low-temperature environments. This helps ensure the heat exchange efficiency of antifreeze and refrigerant inside the power battery cooler, while also ensuring the service life of the power battery cooler. A one-way valve is installed at the refrigerant inlet of the dryer bottle, which can realize the one-way flow of the refrigerant, preventing backflow after the refrigerant enters the dryer bottle, thus maintaining the stable operation of the thermal management system.

[0008] Furthermore, a first temperature and pressure sensor is integrated on the drying bottle.

[0009] Based on the above-mentioned technical means, the temperature and pressure of the refrigerant inside the dryer bottle can be detected, so that the thermal management system can dynamically adjust parameters such as compressor speed, expansion valve opening and refrigerant flow rate according to real-time data, to ensure that the refrigerant enters the power battery cooler with the optimal gas-liquid ratio.

[0010] Furthermore, the thermal management integrated module also includes a first electronic expansion valve, which is integrated on the second side of the flow channel plate assembly and is connected between the refrigerant outlet of the dryer bottle and the refrigerant inlet of the power battery cooler.

[0011] According to the above technical means, since the first electronic expansion valve is connected between the refrigerant outlet of the dryer bottle and the refrigerant inlet of the power battery cooler (referred to as the third refrigerant inlet), the refrigerant flowing out of the dryer bottle can be throttled by the first electronic expansion valve before entering the power battery cooler for heat exchange. After the refrigerant is throttled by the first electronic expansion valve, the pressure and temperature of the refrigerant decrease. When it enters the power battery cooler, it can evaporate and absorb heat in a gas-liquid two-phase state, which is beneficial to improving the heat exchange efficiency between the refrigerant and the antifreeze.

[0012] Furthermore, the thermal management integrated module also includes a water storage bottle, which is integrated on the top of the flow channel plate assembly and is connected to at least one of the external pipeline interfaces.

[0013] Based on the aforementioned technical means, the water storage bottle can be used to store antifreeze and replenish the antifreeze circuit. The water storage bottle is integrated on top of the flow channel plate assembly, positioning it at the highest point of the antifreeze circuit in the thermal management integrated module. The water storage bottle is connected to at least one external pipeline interface. When the antifreeze level drops due to evaporation, leakage, or temperature changes, the water storage bottle can automatically and efficiently replenish the antifreeze circuit via gravity or pressure difference.

[0014] Furthermore, the thermal management integrated module also includes a multi-way water valve, a battery water pump, and an electric drive water pump. The multi-way water valve is connected to multiple external pipeline interfaces to realize the connection control between the antifreeze flow channel and the multiple external pipeline interfaces. The battery water pump and the power battery cooler are both connected to the battery cooling circuit, and the electric drive water pump is connected to the electric drive cooling circuit.

[0015] Based on the aforementioned technical means, the multi-way water valve is connected to multiple external pipeline interfaces, which can be used to realize the connection control between the antifreeze flow channel and multiple external pipeline interfaces, thereby realizing the flow direction control of the antifreeze; the battery water pump and the power battery cooler are both connected to the battery cooling circuit to realize the circulation of antifreeze in the battery cooling circuit, and the flow rate of antifreeze in the battery cooling circuit can be adjusted according to the cooling requirements; the electric drive water pump is connected to the electric drive cooling circuit to realize the circulation of antifreeze in the electric drive cooling circuit, and the flow rate of antifreeze in the electric drive cooling circuit can be adjusted according to the cooling requirements.

[0016] Furthermore, the flow channel plate assembly is provided with a vibration damping connection.

[0017] Based on the above technical means, since the thermal management integrated module is usually installed on the vehicle chassis, cabinet or equipment frame, it is easily affected by road bumps, motor vibration or mechanical impact during operation. The vibration damping connection can isolate the external vibration from being transmitted to the thermal management integrated module through elastic materials (such as rubber, silicone, spring) or damping structures.

[0018] Furthermore, there are multiple vibration damping connections, which are arranged sequentially along the circumference of the flow channel plate assembly.

[0019] Based on the above technical means, multiple fixed mounting points can be formed in the circumference of the flow channel plate assembly, which is beneficial to improving the installation stability of the thermal management integrated module and can prevent the flow channel plate assembly and thermal management integrated module from overturning or shifting under vibration or impact.

[0020] A thermal management system includes the aforementioned thermal management integrated module and a refrigerant circulation loop. The refrigerant circulation loop is equipped with a compressor, a built-in condenser, and an external condenser. The thermal management integrated module also includes a refrigerant control valve, which is integrated on the second side of the flow channel plate assembly. The compressor, the built-in condenser, and the external condenser are respectively connected to the refrigerant control valve.

[0021] Based on the above technical means, since the refrigerant control valve is integrated on the second side of the flow channel plate assembly, and the compressor, built-in condenser and external condenser are respectively connected to the refrigerant control valve, the flow direction of the refrigerant can be controlled through the refrigerant control valve, and the working mode of the refrigerant circulation loop can be switched, thereby meeting the vehicle's working conditions in different scenarios.

[0022] Furthermore, a second temperature and pressure sensor is integrated on the refrigerant control valve.

[0023] Based on the above technical means, the temperature and pressure of the refrigerant inside the refrigerant control valve can be detected, so that the thermal management system can dynamically adjust parameters such as compressor speed, expansion valve opening and refrigerant flow rate according to real-time data, to ensure that the refrigerant enters the external or internal condenser with the optimal gas-liquid ratio.

[0024] Furthermore, the thermal management system also includes an evaporator and a second electronic expansion valve, with the refrigerant outlet of the dryer bottle, the second electronic expansion valve, the evaporator, and the compressor connected in sequence.

[0025] Based on the above-mentioned technical means, the refrigerant, after removing moisture and impurities, can be throttled and depressurized through the second electronic expansion valve, so as to achieve phase change inside the evaporator to cool the passenger compartment, and finally return to the compressor for compression and the next cycle.

[0026] Furthermore, the thermal management system also includes a battery cooling circuit and an electric drive cooling circuit, wherein a battery assembly is provided on the battery cooling circuit and an electric drive assembly is provided on the electric drive cooling circuit.

[0027] Based on the aforementioned technical means, a battery assembly is installed on the battery cooling circuit for temperature management; an electric drive assembly is installed on the electric drive cooling circuit for temperature management. Both the battery cooling circuit and the electric drive cooling circuit are connected to multiple external pipe interfaces of the thermal management integrated module via pipelines to facilitate the circulation of antifreeze in the battery cooling circuit and the electric drive cooling circuit.

[0028] Furthermore, a heater is also provided on the battery cooling circuit, and the heater is connected to the external pipeline interface; The electric drive cooling circuit is also equipped with a radiator and a cooling fan. The radiator is connected to the external pipeline interface, and the cooling fan is correspondingly arranged with the radiator.

[0029] Based on the aforementioned technical means, since the heater is connected to the external piping interface, the antifreeze can be heated, and then the antifreeze flows into the flow channel plate assembly through the external piping interface, and then flows to the battery assembly through other external piping interfaces, thereby raising the temperature of the battery assembly. The radiator is connected to the external piping interface and can be used to cool the antifreeze, so as to ensure the cooling effect of the antifreeze on the electric drive assembly; the cooling fan is correspondingly set to the radiator, and can improve the heat dissipation efficiency of the radiator through air cooling, thereby accelerating the temperature drop of the antifreeze.

[0030] Furthermore, the electric drive cooling circuit includes a bypass branch connected in parallel with the radiator, and a bypass control valve is provided on the bypass branch.

[0031] Based on the above technical means, since a bypass control valve is provided on the bypass branch, the flow rate of antifreeze entering the radiator can be controlled by the bypass control valve, thereby achieving precise control of the antifreeze temperature.

[0032] A vehicle including the aforementioned thermal management system.

[0033] Based on the aforementioned technical means, the integrated setup of thermal management components inside the vehicle can be achieved. The thermal management integration module connects multiple external pipeline interfaces and multiple refrigerant interfaces to the battery cooling circuit, electric drive cooling circuit, and refrigerant circulation circuit respectively through pipelines. It can adapt and switch the battery cooling circuit, electric drive cooling circuit, and refrigerant circulation circuit according to different vehicle scenarios.

[0034] The beneficial effects of this application are: (1) This application integrates components such as power battery cooler and dryer bottle on flow channel plate assembly, which can reduce the mounting brackets and pipelines of components, realize the requirements of vehicle lightweighting, and reduce the occupancy rate of engine compartment space of thermal management system.

[0035] (2) This application dries and removes impurities from the refrigerant entering the power battery cooler by using a drying bottle, which can prevent the refrigerant moisture from freezing and blocking or corroding the second heat exchange pipeline in low-temperature environments. This is beneficial to ensuring the heat exchange efficiency of the antifreeze and refrigerant inside the power battery cooler, and at the same time, ensuring the service life of the power battery cooler.

Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application.

In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0040] Please see Figures 1 to 14 The first aspect of this application proposes a thermal management integrated module 1, including a flow channel plate assembly 11, a power battery cooler 12, and a desiccant bottle 13. The flow channel plate assembly 11 has a first side and a second side that are opposite to each other, and mounting spaces for integrating multiple components can be formed on both sides of the flow channel plate assembly 11. An antifreeze flow channel 111 is provided inside the flow channel plate assembly 11, allowing antifreeze to flow inside the flow channel plate assembly 11. The first side of the flow channel plate assembly 11 has multiple external pipe interfaces 112 communicating with the antifreeze flow channel 111, allowing antifreeze in the antifreeze flow channel 111 to flow out through any one or more external pipe interfaces 112, realizing the delivery and circulation of antifreeze. Figure 1 and Figure 5 As shown.

[0041] The power battery cooler 12 is integrated on the second side of the flow channel plate assembly 11, avoiding interference with multiple external pipeline interfaces 112. The power battery cooler 12 internally includes a first heat exchange pipeline and a second heat exchange pipeline (not shown in the figure), which are used to realize the flow of antifreeze and refrigerant, respectively, and to achieve heat exchange between the antifreeze and refrigerant through the first and second heat exchange pipelines. Specifically, the first heat exchange pipeline is connected to the antifreeze flow channel 111 of the flow channel plate assembly 11, enabling the flow of antifreeze within the first heat exchange pipeline. Correspondingly, the second heat exchange pipeline is connected to the refrigerant circulation loop 2, enabling the flow of refrigerant within the second heat exchange pipeline.

[0042] The dryer bottle 13 is integrated on the second side of the flow channel plate assembly 11, and a one-way valve 133 is provided at the refrigerant inlet of the dryer bottle 13. Figure 2 , Figure 3 and Figure 4 As shown, unidirectional flow of the refrigerant can be achieved, preventing backflow after the refrigerant enters the dryer bottle 13, thus maintaining the stable operation of the thermal management system. The refrigerant outlet of the dryer bottle 13 is connected to the refrigerant inlet of the second heat exchange pipeline, allowing the refrigerant to pass through the dryer bottle 13 to remove moisture and impurities before entering the power battery cooler 12 for heat exchange. Before the refrigerant enters the power battery cooler 12, the dryer bottle 13 can effectively remove moisture from the refrigerant, preventing moisture from freezing and clogging or corroding the second heat exchange pipeline in low-temperature environments. This helps ensure the heat exchange efficiency of the antifreeze and refrigerant inside the power battery cooler 12, while also ensuring the service life of the power battery cooler 12.

[0043] In some embodiments of this application, please refer to Figure 4 The desiccant bottle 13 includes multiple refrigerant inlets (such as a first refrigerant inlet 131 and a second refrigerant inlet 132), each of which is equipped with a one-way valve 133, enabling unidirectional refrigerant input from multiple refrigerant branches. Specifically, the first refrigerant inlet 131 is connected to the external condenser 23 in the thermal management system, allowing refrigerant from the external condenser 23 to flow into the desiccant bottle 13 through the first refrigerant inlet 131. The second refrigerant inlet 132 is connected to the internal condenser 22 in the thermal management system, allowing refrigerant from the internal condenser 22 to flow into the desiccant bottle 13 through the second refrigerant inlet 132. Specifically, the one-way valve 133 can be fixedly installed at the refrigerant inlet of the desiccant bottle 13 using components such as a snap ring.

[0044] In some embodiments of this application, please refer to Figure 4 The dryer bottle 13 is equipped with a first temperature and pressure sensor 136, which can detect the temperature and pressure of the refrigerant inside the dryer bottle 13. This allows the thermal management system to dynamically adjust parameters such as the compressor 21 speed, expansion valve opening, and refrigerant flow rate based on real-time data, ensuring that the refrigerant enters the power battery cooler 12 with the optimal gas-liquid ratio. Specifically, the first temperature and pressure sensor 136 can be fixedly mounted on the dryer bottle 13 via a threaded connection or other means.

[0045] In some embodiments of this application, please refer to Figure 2 and Figure 3The thermal management integrated module 1 also includes a first electronic expansion valve 14, which is integrated on the second side of the flow channel plate assembly 11. The first electronic expansion valve 14 is connected between the refrigerant outlet of the dryer bottle 13 and the refrigerant inlet (referred to as the third refrigerant inlet) of the power battery cooler 12, so that the refrigerant flowing out of the dryer bottle 13 can be throttled by the first electronic expansion valve 14 before entering the power battery cooler 12 for heat exchange. After the refrigerant is throttled by the first electronic expansion valve 14, the pressure and temperature drop, and when it enters the power battery cooler 12, it can evaporate and absorb heat in a gas-liquid two-phase state, which is beneficial to improving the heat exchange efficiency between the refrigerant and the antifreeze.

[0046] In some embodiments of this application, please refer to Figure 2 and Figure 3 The first electronic expansion valve 14 is bolted to the power battery cooler 12, which reduces the mounting area occupied by the first electronic expansion valve 14 on the flow channel plate assembly 11, and helps to reduce the overall volume of the thermal management integrated module 1. The dryer bottle 13 is connected to the first electronic expansion valve 14 through an external pipeline, which simplifies the pipeline integration on the refrigerant side, improves reliability, simplifies the manufacturing process, and reduces costs.

[0047] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 The refrigerant outlet of the power battery cooler 12 is designated as the first refrigerant outlet 121, and the first refrigerant outlet 121 is used to connect to the air inlet of the compressor 21 of the thermal management system. The dryer bottle 13 has multiple refrigerant outlets (such as the second refrigerant outlet 134 and the third refrigerant outlet 135), which can output the refrigerant after removing moisture and impurities to different components. Specifically, the second refrigerant outlet 134 is connected to the inlet of the second electronic expansion valve 25 in the thermal management system through an external pipeline, and the third refrigerant outlet 135 is connected to the inlet of the first electronic expansion valve 14 through a pipeline. This allows a portion of the refrigerant to flow through the first refrigerant outlet 121 into the second electronic expansion valve 25 and the evaporator 24, thereby cooling the passenger compartment. Another portion of the refrigerant flows through the second refrigerant outlet 134 into the first electronic expansion valve 14 and the power battery cooler 12 to exchange heat with the antifreeze, thereby cooling the battery assembly 31.

[0048] In some embodiments of this application, please refer to Figures 1 to 3The thermal management integrated system also includes a water storage bottle 15, which can be used to store antifreeze and replenish the antifreeze circuit. The water storage bottle 15 is integrated on top of the flow channel plate assembly 11, placing it at the highest point of the antifreeze circuit in the thermal management integrated module 1. The water storage bottle 15 is connected to at least one external pipeline interface 112. When the antifreeze level drops due to evaporation, leakage, or temperature changes, the water storage bottle 15 can automatically and efficiently replenish the antifreeze circuit via gravity or pressure difference. Specifically, the water inlet 151 of the water storage bottle 15 is connected via an external pipeline to the sixth external pipeline interface 112f on the flow channel plate assembly 11 closest to the water storage bottle 15. This reduces the complexity of pipeline layout while enabling efficient replenishment of the antifreeze circuit by the water storage bottle 15.

The flow rate of antifreeze in the battery cooling circuit 3 can be adjusted according to the cooling requirements. The electric drive water pump 18 is connected to the electric drive cooling circuit 4 to realize the circulation of antifreeze in the electric drive cooling circuit 4. The flow rate of antifreeze in the electric drive cooling circuit 4 can be adjusted according to the cooling requirements.

The refrigerant circulation loop 2 is provided with a compressor 21, an internal condenser 22 and an external condenser 23. The thermal management integrated module 1 also includes a refrigerant control valve 19, which is integrated on the second side of the flow channel plate assembly 11. The compressor 21, the internal condenser 22 and the external condenser 23 are respectively connected to the refrigerant control valve 19. The flow direction of the refrigerant can be controlled through the refrigerant control valve 19, and the working mode of the refrigerant circulation loop 2 can be switched to meet the working conditions of the vehicle in different scenarios.

[0058] It should be noted that this application integrates the battery water pump 17, multi-way water valve 16, and electric water pump 18 on the first side of the flow channel plate assembly 11, and integrates the power battery cooler 12, first electronic expansion valve 14, dryer bottle 13, and refrigerant control valve 19 on the second side of the flow channel plate assembly 11. This allows for water-side integration (i.e., antifreeze component integration) and refrigerant component integration on both sides of the flow channel plate assembly 11. This arrangement separates the antifreeze circuit and refrigerant circuit as much as possible, effectively avoiding mutual interference between them, reducing connecting pipes, and facilitating installation. Specifically, the battery water pump 17, multi-way water valve 16, electric water pump 18, power battery cooler 12, first electronic expansion valve 14, dryer bottle 13, and refrigerant control valve 19 can all be bolted onto the flow channel plate assembly 11.

[0059] In some embodiments of this application, please refer to Figures 7 to 11 The refrigerant control valve 19 is a two-position three-way valve with a first refrigerant port 192, a second refrigerant port 193, and a third refrigerant port 194. The first refrigerant port 192 is connected to the refrigerant inlet of the external condenser 23 through an external pipeline, the second refrigerant port 193 is connected to the refrigerant inlet of the built-in condenser 22 through an external pipeline, and the third refrigerant port 194 is connected to the exhaust port of the compressor 21 through an external pipeline. In different operating modes, the refrigerant discharged by the compressor 21 can flow into the external condenser 23 or the built-in condenser 22 through the refrigerant control valve 19.

[0060] At the same time, replacing the internal flow channels integrated on the refrigerant side with external piping connections can simplify the piping integration on the refrigerant side, improve reliability, simplify the manufacturing process, and reduce costs.

[0061] Specifically, the refrigerant circulation loop 2 includes a cooling mode and a heating mode. In the cooling mode, the first refrigerant port 192 of the refrigerant control valve 19 is opened and connected to the external condenser 23, while the second refrigerant port 193 is closed. At this time, the thermal management integrated module 1, compressor 21, evaporator 24, second electronic expansion valve 25, and external condenser 23 form a closed loop. The refrigerant is compressed inside the compressor 21 to form a high-temperature, high-pressure gaseous refrigerant, which then flows through the refrigerant control valve 19 into the external condenser 23 for cooling to form a high-temperature, high-pressure liquid refrigerant. Part of the liquid refrigerant flows through the pipeline into the second electronic expansion valve 25 for throttling and then enters the evaporator 24 to exchange heat with the passenger compartment, thus cooling the passenger compartment. The other part flows into the power battery cooler 12 on the thermal management integrated module 1 to exchange heat with the antifreeze in the battery cooling loop 3, thus cooling the battery assembly 31. After heat exchange, it enters the compressor 21 for compression, forming a cycle.

[0062] In heating mode, the refrigerant control valve 19 opens the second refrigerant interface 193 to connect with the built-in condenser 22 and closes the first refrigerant interface 192. At this time, the thermal management integrated module 1, compressor 21, built-in condenser 22, and second electronic expansion valve 25 form a closed loop. The refrigerant is compressed inside the compressor 21 to form a high-temperature and high-pressure gaseous refrigerant, which then flows into the built-in condenser 22 through the refrigerant control valve 19 to exchange heat with the passenger compartment and heat the passenger compartment. The cooled refrigerant passes through the power battery cooler 12 and exchanges heat with the antifreeze in the battery cooling circuit 3 inside it to cool the battery assembly 31 and recover heat. After heat exchange, it enters the compressor 21 for compression, forming a cycle.

[0063] In some embodiments of this application, please refer to Figure 7 A second temperature and pressure sensor 191 is integrated on the refrigerant control valve 19. This sensor detects the temperature and pressure of the refrigerant inside the valve, allowing the thermal management system to dynamically adjust parameters such as the compressor 21 speed, expansion valve opening, and refrigerant flow rate based on real-time data. This ensures that the refrigerant enters the external condenser 23 or the internal condenser 22 with the optimal gas-liquid ratio. Specifically, the second temperature and pressure sensor 191 can be fixedly mounted on the refrigerant control valve via a threaded connection or other means.

[0064] In some embodiments of this application, please refer to Figures 8 to 11 The thermal management system also includes an evaporator 24 and a second electronic expansion valve 25. The refrigerant outlet of the dryer bottle 13 (i.e., the second refrigerant outlet 134), the second electronic expansion valve 25, the evaporator 24 and the compressor 21 are connected in sequence, so that the refrigerant after removing moisture and impurities can be throttled and depressurized through the second electronic expansion valve 25, so as to achieve phase change inside the evaporator 24 to cool the passenger compartment, and finally return to the compressor 21 for compression and the next cycle.

[0065] In some embodiments of this application, please refer to Figure 8 , Figure 12 and Figure 13 The thermal management system also includes a battery cooling circuit 3 and an electric drive cooling circuit 4. The battery cooling circuit 3 is equipped with a battery assembly 31, which can be used for temperature management of the battery assembly 31. The electric drive cooling circuit 4 is equipped with an electric drive assembly 41, which can be used for temperature management of the electric drive assembly 41. Both the battery cooling circuit 3 and the electric drive cooling circuit 4 are connected to multiple external pipe interfaces 112 of the thermal management integrated module 1 via pipelines to facilitate the circulation of antifreeze in the battery cooling circuit 3 and the electric drive cooling circuit 4. Specifically, the battery water pump 17 provides power for the flow of antifreeze in the battery cooling circuit 3, and the electric drive water pump 18 provides power for the flow of antifreeze in the electric drive cooling circuit 4.

[0066] In some embodiments of this application, please refer to Figure 8 and Figure 13 The battery cooling circuit 3 is also equipped with a heater 32, which is connected to the external pipeline interface 112. It can heat the antifreeze and then allow the antifreeze to flow into the flow channel plate assembly 11 through the external pipeline interface 112, and flow to the battery assembly 31 through other external pipeline interfaces 112, thereby raising the temperature of the battery assembly 31.

[0067] In some embodiments of this application, please refer to Figure 8 and Figure 14 The electric drive cooling circuit 4 is also equipped with a radiator 42 and a cooling fan 43. The radiator 42 is connected to the external pipeline interface 112 and can be used to cool the antifreeze so as to ensure the cooling effect of the antifreeze on the electric drive assembly 41. The cooling fan 43 is set in correspondence with the radiator 42 and can improve the heat dissipation efficiency of the radiator 42 by air cooling, thereby accelerating the temperature drop efficiency of the antifreeze.

[0068] In some embodiments of this application, please refer to Figure 8 The cooling fan 43, external condenser 23 and radiator 42 are arranged in sequence. The cooling fan 43 can blow cold air to the external condenser 23 and radiator 42 at the same time, thereby cooling the refrigerant inside the external condenser 23 and the antifreeze inside the radiator 42. This can reduce the number of cooling fans 43 and reduce the installation cost of the thermal management system.

[0069] In some embodiments of this application, please refer to Figure 8 and Figure 14 The electric drive cooling circuit 4 includes a bypass branch 44 connected in parallel with the radiator 42. A bypass control valve 45 is provided on the bypass branch 44, which can control the flow rate of antifreeze entering the radiator 42, thereby achieving precise control of the antifreeze temperature.

[0070] In some embodiments of this application, please refer to Figure 1 , Figure 5 and Figure 8 The thermal management integrated module 1 is equipped with seven external pipe interfaces 112, which are respectively designated as the first external pipe interface 112a, the second external pipe interface 112b, the third external pipe interface 112c, the fourth external pipe interface 112d, the fifth external pipe interface 112e, the sixth external pipe interface 112f, and the seventh external pipe interface 112g. The first external pipe interface 112a is connected to the antifreeze inlet of the heater 32 via a pipe, and the third external pipe interface 112c is connected to the antifreeze outlet of the heater 32 via a pipe, allowing the heated antifreeze to flow back into the flow channel plate assembly 11. The second external pipe interface 112b is connected to the inlet of the third heat exchange pipe flowing through the battery assembly 31, allowing the antifreeze to be used to heat the battery. The assembly 31 is cooled or heated. The fourth external pipe interface 112d is connected to the outlet of the third heat exchange pipe, so that the antifreeze after heat exchange with the battery assembly 31 flows back to the interior of the flow channel plate assembly 11. The seventh external pipe interface 112g is connected to the antifreeze inlet of the bypass control valve 45 through a pipe, so that the antifreeze flows into the fourth heat exchange pipe that flows through the electric drive assembly 41, and cools the electric drive assembly 41 through the antifreeze. The antifreeze outlet of the fourth heat exchange pipe is connected to the fifth external pipe interface 112e through a pipe, so that the antifreeze after heat exchange with the electric drive assembly 41 flows back to the interior of the flow channel plate assembly 11. The sixth external pipe interface 112f is connected to the water inlet 151 of the water storage bottle 15 through a pipe, so that the water storage bottle 15 can be replenished with antifreeze in a timely manner.

[0071] In some embodiments of this application, the multi-way water valve 16 has a first working mode and a second working mode, and can control the flow of antifreeze through the multi-way water valve 16 to meet the needs of different operating conditions of the vehicle.

[0072] Specifically, in the first working mode, the first external interface 161 and the second external interface 162 are connected inside the multi-way water valve 16, and the sixth external interface 166 and the seventh external interface 167 are connected inside the multi-way water valve 16. At this time, the battery assembly 31, heater 32, thermal management integrated module 1, electric drive assembly 41, radiator 42, and bypass control valve 45 form an independent circulation loop. In this working mode, the heat of the electric drive assembly 41 can be recovered through antifreeze and provided to the battery assembly 31 for use, while the excess heat can be dissipated through the radiator 42.

[0073] In the second operating mode, the first external interface 161 and the seventh external interface 167 are connected inside the multi-way water valve 16, and the second external interface 162 and the sixth external interface 166 are connected inside the multi-way water valve 16. At this time, the battery assembly 31, the heater 32, and the thermal management integrated module 1 form an independent battery cooling circuit 3, which can cool or heat the battery assembly 31 individually through the antifreeze flowing in the battery cooling circuit 3; while the thermal management integrated module 1, the electric drive assembly 41, the radiator 42, and the bypass control valve 45 form an independent electric drive cooling circuit 4, and the heat absorbed by the antifreeze from the electric drive assembly 41 can be dissipated through the radiator 42.

[0074] In the first or second working mode, if the battery assembly 31 requires cooling or heating, the third external interface 163 and the fourth external interface 164 can be connected inside the multi-way water valve 16, and the third heat exchange pipeline flowing through the battery assembly 31 can be connected in series to the battery cooling circuit 3 for cooling or heating the battery assembly 31; when the battery assembly 31 does not require cooling or heating, the fourth external interface 164 and the fifth external interface 165 can be connected inside the multi-way water valve 16, thereby disconnecting the third heat exchange pipeline flowing through the battery assembly 31 from the battery cooling circuit 3.

[0075] Please see Figures 1 to 14 The third aspect of this application proposes a vehicle including the thermal management system described in the above embodiments. This thermal management system enables the integrated installation of thermal management components within the vehicle. The thermal management integration module 1 connects multiple external pipeline interfaces 112 and multiple refrigerant interfaces to the battery cooling circuit 3, the electric drive cooling circuit 4, and the refrigerant circulation circuit 2 respectively via pipelines. The module can adapt and switch between the battery cooling circuit 3, the electric drive cooling circuit 4, and the refrigerant circulation circuit 2 according to different vehicle scenarios.

[0076] In some embodiments of this application, the vehicle is a new energy vehicle. Through the above-mentioned thermal management system, the linkage and energy transfer between the battery cooling circuit 3, the electric drive cooling circuit 4 and the refrigerant circulation circuit 2 can be realized, which can improve the energy utilization rate while simplifying the layout of the thermal management system.

[0077] The thermal management integrated module 1 of this application integrates components such as pumps, valves, power battery coolers 12, and dryers 13 onto the flow channel plate assembly 11. This reduces the number of mounting brackets and pipelines for components, achieving the vehicle's lightweight requirements and reducing the space occupied by the thermal management system in the engine compartment. Through the thermal management integrated module 1 and the thermal management system of this application, the mode switching of the battery cooling circuit 3, the motor cooling circuit, and the passenger compartment circuit (i.e., the refrigerant circulation circuit 2) can also be realized, while heat exchange between the coolant antifreeze circuit and the refrigerant circuit can be achieved, which can meet the single or multiple scenario requirements of the vehicle's battery assembly 31, electric drive assembly 41, and passenger compartment.
