The motor radiator 92 is used to cool and dissipate heat for both the motor 91 and the cabin air conditioning system. The cooling pipe of the battery 8 is connected in series with the cooling pipe of the battery heat exchanger 2, and the cooling capacity of the battery heat exchanger 2 is used to cool and dissipate heat for the battery 8.

The cooling pipe containing battery 8 is connected in series with the cooling pipe containing battery heat exchanger 2. Positive temperature coefficient heater 81 heats battery 8, and the heat from battery 8 is transferred to battery heat exchanger 2. Battery heat exchanger 2 uses the heat pump circulation of the refrigeration system to raise the heat to a high level and use it to heat the cabin air conditioning components; the cabin air conditioning components operate independently.

The cooling pipes of the battery 8, the battery heat exchanger 2, the front-end heat exchange module (including the motor radiator 92 and the microchannel condenser 93), and the motor 91 are sequentially connected to form a closed loop. The heat generated by the battery 8 is exchanged with the air in the battery heat exchanger 2. The front-end heat exchange module 2 is used to cool and dissipate heat for the cabin air conditioning components.

[0061] like Figure 1 , Figure 2 and Figure 12 As shown, in natural heating operation mode, ports A and B of the first four-way valve 121 are connected, as are ports D and C. Ports E and H of the second four-way valve 122 are connected, as are ports F and G. The motor 91 is connected to the first four-way valve 121 via a three-way valve 11. The cooling pipes of the battery 8, the battery heat exchanger 2, and the motor 91 are sequentially connected to form a closed loop. The heat generated by the electric control of the motor 91 heats the battery 8 through the battery heat exchanger 2, and simultaneously, the positive temperature coefficient heater 81 also heats the battery 8.
