The refrigerant circulation working circuit is divided into an evaporation area and a condensation area, which respectively belong to a high-pressure area or a low-pressure area. The compressor 1 extracts the refrigerant from the low-pressure area, sends the refrigerant to the high-pressure area condenser 6 after compression for cooling and condensing, and conducts the heat energy of the condenser 6 into the air through the wind of the electronic fan 7, and the refrigerant also changes from the gas state to the liquid state and increases the pressure. The refrigerant flows from the high pressure region to the low pressure region, enters the heat exchanger 5, the pressure suddenly drops, the liquid refrigerant immediately becomes gaseous, and a large amount of heat in the battery box 9 is absorbed by the heat exchanger 5. In this way, the machine continuously works, and heat energy at one end of the low-pressure area is absorbed into the refrigerant and then sent to the high-pressure area to be emitted into the air, so that the effect of adjusting the battery pack in the battery box 9 is achieved.
