[0038] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0039] To facilitate understanding of the technical solutions and technical effects of the embodiments of the present application, the prior art of the present application will be briefly described below.

[0040] The popularity of new energy vehicles has increased significantly. However, due to limitations in battery technology, the range and refueling efficiency of pure electric vehicles remain challenges for major vehicle manufacturers. To increase the range of pure electric vehicles, major vehicle manufacturers are adopting innovative technologies to improve vehicle energy efficiency and reduce energy consumption. At the same time, they are striving to optimize the design of various vehicle systems to further enhance overall energy efficiency. In pure electric vehicles, the thermal management system is a major energy consumer. Under high and low temperature operating conditions, its power consumption can account for over 40% of the vehicle's total power consumption, and in some cases, as much as 50%. To reduce thermal management system power consumption, major vehicle manufacturers are adopting heat pump systems with various system architectures to minimize air conditioning power consumption during driving. In daily use, they are also considering using waste heat from the electric drive for the battery, passenger compartment, or even heat pump systems, which doubles the complexity of the thermal management system architecture compared to traditional models. With the increasing complexity of the system architecture, the number of pipes, pumps, and valves in the 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 assembly efficiency of the vehicle.

[0041] In order to improve the assembly efficiency of the thermal management system, flow channels in the flow channel plate are usually used to replace the internal pipes in the thermal management system to reduce the assembly difficulty of the thermal management system.

[0042] Under the existing technology, the flow channel plate usually includes two layers, and the two layers of flow channel plates can cooperate to form a flow channel. Vehicles usually include three cooling circuits, namely the battery cooling circuit, the electric drive cooling circuit and the 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 side of the flow channel plate, which will increase the safety risks of the vehicle's heat dissipation process.
