The new energy battery on the inside is cooled down. After the cold water is in contact with the new energy battery, the temperature of the cooling water is increased through heat transfer. The water after the temperature rise is opened by the circulating water pump 8 and the second solenoid valve 7. , pressurize the water with increased temperature, and pump the water into the medium inlet end of the evaporator 5. At this time, the low-temperature and low-pressure refrigerant liquid is evaporated in the evaporator 5 to absorb the heat of the cooling water, so that the cooling water is further cooled. , to achieve low-temperature cold water for cooling the cooling water of the new energy battery. In this process, the radiator 12 does not participate in the work, saving electric energy, improving the operating efficiency and life of the new energy battery air conditioning cooling system, and the heat emitted by the new energy battery is effectively discharged. And cooling, to ensure the stable and reliable operation of the new energy battery, improve the life of the new energy battery.
