[0041] As mentioned above, in the thermal management device, thermal management system and vehicle provided by the relevant technology, there is a problem that the various components are connected by pipes, and the integration of the thermal management device is not high, which leads to cumbersome assembly process between the various components, and thus makes the assembly of the thermal management device more difficult.

[0042] In view of this, the present application provides a thermal management integrated device, a thermal management integrated system and a vehicle to solve the technical problems existing in the above-mentioned prior art.

[0043] The vehicle provided in the present application includes a thermal management integrated system, which can change the temperature environment in the vehicle so that the driver and passengers can have a good driving experience. At the same time, the thermal management integrated system is also used to perform thermal management on other functional components in the vehicle.

[0044] Specifically, the thermal management integrated system includes a thermal management integrated device, an external heating circuit, an external battery circuit, and an external motor circuit. The thermal management integrated device forms a circulation loop with the external heating circuit, the external battery circuit, and the external motor circuit, respectively, and the external battery circuit and the external motor circuit can be connected, so that the thermal management integrated system has multiple heat exchange modes. The thermal management integrated device can also be used to connect other functional components in the thermal management integrated system to realize the heat pipe function.

[0047] In the existing thermal management device, since the components are connected by pipelines, the integration of the thermal management device is not high, resulting in a cumbersome assembly process between the components, which makes the assembly of the thermal management device difficult.

[0048] Therefore, the present application provides a thermal management integrated device to solve the above problems. The thermal management integrated device provided by the present application is described in detail below.

[0050] In this embodiment, the thermal management integrated device 100 includes a flow channel plate 10, which is used as a carrier to integrate multiple components. The flow channel plate 10 has multiple flow channels 11, so that the components integrated on the flow channel plate 10 can be connected through the flow channels 11 to form a circulation loop.

On the one hand, since the multiple flow channels 11 integrate the heating circuit, the battery circuit and the motor circuit on the flow channel plate 10, there is no need to set pipes and other components to form connections between the individual units of the heating circuit, between the individual units of the battery circuit, between the individual units of the motor circuit, and between the heating circuit, the battery circuit and the motor circuit, thereby reducing the parts and consumables of the thermal management integrated device 100, facilitating assembly, and helping to reduce the manufacturing cost of the thermal management integrated device 100. On the other hand, there is no need to set pipes and other components to form connections between the individual units of the heating circuit, between the individual units of the battery circuit, between the individual units of the motor circuit, and between the heating circuit, the battery circuit and the motor circuit, thereby helping to improve the space utilization of the thermal management integrated device 100. On the other hand, since the thermal management integrated device 100 has fewer components, the probability of the thermal management integrated device 100 failing due to component failure is relatively small, which is beneficial to improving the reliability and stability of the thermal management integrated device 100 during operation.

[0053] In a specific embodiment, among the multiple valves 20, each valve 20 includes a valve body 21, at least one fixing member 22 and a sealing ring 23. The valve body 21 is plugged into the flow channel plate 10, the fixing member 22 passes through the valve body 21 and fixes the valve body 21 to the flow channel plate 10, and the sealing ring 23 is sealed between the valve body 21 and the flow channel plate 10 along the circumference of the valve body 21. The valve body 21 is sealed and integrated with the flow channel plate 10 by the fixing member 22 and the sealing ring 23, so that the connection stability and sealing stability between the valve 20 and the flow channel plate 10 are better, thereby making the adjustment stability of the valve 20 better during the working process, thereby ensuring the performance of the thermal management integrated device 100.

[0055] See also Figure 1 , Figure 2 In a specific embodiment, a plate changer 40 is integrated on the flow channel plate 10, and the plate changer 40 is connected between the external warm air circuit and the external battery circuit through the flow channel 11, so that heat exchange is formed between the external warm air circuit and the external battery circuit. Through the setting of the plate changer 40, heat exchange can be formed between the external warm air circuit and the battery circuit. At the same time, the plate changer 40 can also prevent the high-temperature heat exchange medium from flowing directly to the battery circuit, which can reduce the impact of the heat exchange medium on the battery circuit, and further reduce the occurrence of thermal runaway in the battery circuit. It can be understood that in some other embodiments, the plate changer 40 can be replaced by a four-way water valve, and the present application does not limit this.

[0056] See also Figure 2 , Figure 7 and Figure 8 , Figure 7 is an assembly diagram of a flow channel plate provided in one embodiment of the present application, Figure 8 This is an exploded view of a flow channel plate provided in one embodiment of the present application.

[0057] In a specific embodiment, the flow channel plate 10 includes a first plate body 12 and a second plate body 13, and the first plate body 12 and the second plate body 13 are sealed and overlapped by a welding process to form a plurality of flow channels 11. A plurality of valves 20, a plurality of driving members 30 and a plate changer 40 are all arranged on the side of the first plate body 12 away from the second plate body 13. By overlapping the first plate body 12 and the second plate body 13 to form a plurality of flow channels 11, the difficulty of forming the flow channels 11 on the flow channel plate 10 can be reduced, and the processing of the flow channels 11 is facilitated. At the same time, the plurality of valves 20, the plurality of driving members 30 and the plate changer 40 are all integrated on the side of the first plate body 12 away from the second plate body 13, which facilitates the assembly and maintenance of the thermal management integrated device 100.

[0058] See also Figure 1 , Figure 2 , Figure 7 and Figure 8In a specific embodiment, the plurality of valves 20 include a four-way valve 201 and a five-way valve 202, and the plurality of driving members 30 include a warm air pump 301, a battery pump 302, and a motor pump 303. The four-way valve 201, the five-way valve 202, the warm air pump 301, the battery pump 302, and the motor pump 303 are all integrated on the side of the first plate body 12 of the flow channel plate 10 away from the second plate body 13.

[0059] Among them, the flow channel plate 10 provides multiple flow channels 11 and multiple mounting interfaces for each component that needs to be connected, so that the thermal management integrated device 100 can form multiple circulation loops. The plate changer 40 is connected between the external warm air circuit and the external battery circuit, and is used to allow the external warm air circuit and the external battery circuit to exchange heat. The four-way valve 201 is connected between the plate changer 40 and the external battery circuit, and is used to allocate and control the heat exchange between the external warm air circuit and the external battery circuit as required. The five-way valve 202 is connected between the external battery circuit and the external motor circuit, and is used to allocate and control the heat exchange between the external battery circuit and the external motor circuit as required. The warm air pump 301 is used to provide circuit power for the heat exchange medium in the external warm air circuit. The battery pump 302 is used to provide circuit power for the heat exchange medium in the external battery circuit. The motor pump 303 is used to provide circuit power for the heat exchange medium in the external motor circuit.

[0060] See also Figure 2 , Figure 5 and Figure 6 Furthermore, the four-way valve 201 and the five-way valve 202 are both piston valves. By setting the four-way valve 201 and the five-way valve 202 as piston valves, the probability of internal leakage of the four-way valve 201 and the five-way valve 202 can be reduced, which is conducive to reducing the loss of heat exchange between different flow channels 11, thereby improving the overall heat exchange efficiency of the thermal management integrated device 100, and also helping to reduce energy consumption.

The elastic member 25 is sleeved outside the support column 14, and the elastic member 25 is connected between the flow channel plate 10 and the valve core 24 to provide a support force for the valve core 24 to open. The cam 26 is rotated by the actuator and controls the opening and closing of the valve core 24. Among them, the support column 14 is integrally formed with the flow channel plate 10. By setting the support column 14 on the flow channel plate 10 and integrally forming it with the flow channel plate 10, the integration of the flow channel plate 10 and the thermal management integrated device 100 is higher, which is conducive to reducing the difficulty of assembly, improving assembly efficiency, and thus reducing assembly costs.

The four-way valve 201 is then used to control whether the heat exchange medium passes through the plate 40. Then it enters the five-way valve 202 to return to the battery pump 302 or enter the external motor circuit. In this embodiment, the battery control module is connected in parallel with the battery cold plate, and heat exchange of the battery control module can be achieved. Of course, in some other embodiments, the battery control module can be replaced with other components that require heat exchange, and this application does not limit this.

[0083] Specifically, the heat exchange medium of the external motor circuit flows out of the motor pump 303, passes through the ninth connecting hole 109 (motor cold plate inlet), and enters the motor cold plate. After the heat exchange medium flows out of the motor cold plate, it passes through the sixth connecting hole 106 (motor cold plate outlet) and enters the five-way valve 202. It is controlled by the five-way valve 202: in one mode, it enters the radiator through the seventh connecting hole 107 (radiator inlet), and then returns to the five-way valve 202 through the eighth connecting hole 108 (radiator outlet), and returns to the motor pump 303. In another mode, it enters the external battery circuit through the battery pump 302. In one mode, it directly returns to the motor pump 303.

[0084] In summary, the circulation loop formed between the thermal management integrated device 100 and the external heating circuit, the external battery circuit and the external motor circuit, and the four-way valve 201 and the five-way valve 202 are arranged in the circulation loop. When the thermal management integrated device and the thermal management integrated system are applied to the vehicle, the following functions can be achieved in conjunction with the refrigerant circuit:

[0085] Air conditioning heating and dehumidification; air conditioning heating and battery heating, dehumidification and battery heating, and defrosting of the vehicle's external heat exchanger; air conditioning heating and battery cooling, dehumidification and battery cooling; battery cooling; motor cooling and battery cooling; motor cooling; motor heat storage, motor self-circulation, motor waste heat heating battery, heat pump recovery of battery and motor waste heat, thereby enabling the vehicle to achieve thermal management of the entire vehicle.

[0086] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
