The details in this specification can also be based on different viewpoints and applications, and various modifications or changes can be made without departing from the spirit of the utility model. It should be understood that the optional embodiments are only for illustrating the utility model, not for limiting the scope of protection of the utility model.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0031] To facilitate understanding of the technical solutions and technical effects of the embodiments of the present invention, the prior art of the present invention will be briefly described below.

[0032] The popularity of new energy vehicles has increased significantly. However, due to the limitations of battery technology, the mileage and energy replenishment efficiency of pure electric vehicles are still a problem that restricts the development of major vehicle manufacturers. In order to increase the mileage of pure electric vehicles, major vehicle manufacturers have adopted innovative technologies to improve the energy utilization efficiency of the whole vehicle and reduce energy consumption. At the same time, they strive to optimize the design of each system of the whole vehicle to further improve the comprehensive utilization efficiency of energy. In pure electric vehicles, the thermal management system is a major energy consumer. Under high and low temperature conditions, its power consumption can account for more than 40% of the power consumption of the whole vehicle, and even up to 50% in some cases. In order to reduce the power consumption of the thermal management system, major vehicle manufacturers have adopted heat pump systems with different system architectures to minimize the power consumption of air conditioning during driving. In daily use, they also consider using the waste heat of the electric drive for batteries or passenger compartments, or even for heat pump systems, which doubles the complexity of the thermal management system architecture compared to traditional models. With the increase in the complexity of the system architecture, the number of pipelines and pumps and valves in the whole vehicle has increased significantly. The increase in the number of parts leads to many problems in the layout of vehicle parts and pipelines. It will also increase the number of assembly processes and time, affecting the efficiency of vehicle assembly.

[0033] In order to improve the assembly efficiency of the thermal management system, flow channels in the flow channel plate are usually used to replace internal pipes in the thermal management system to reduce the difficulty of assembling the thermal management system.

Vehicles usually include three cooling circuits, namely a battery cooling circuit, an electric drive cooling circuit, and a heating cooling circuit. The cooling circuits are respectively connected to the flow channels to achieve heat dissipation of the vehicle. However, as the heat dissipation demand of the vehicle increases, the flow channel formed between the two layers of flow channel plates cannot meet the heat dissipation demand of the vehicle. And if a flow channel plate composed of two layers of flow channels is used, then in the thermal management system, the cooling circuit can only be set on one layer of the flow channel plate, which will increase the safety risks of the vehicle's heat dissipation process.
