The refrigerant is compressed into high-temperature and high-pressure gas by the compressor 34 and enters the microchannel condenser 36. The heat is released into the surrounding air environment through the condensing fan 40 through the condensing of the refrigerant. The refrigerant flowing out of the microchannel condenser 36 is filtered by the drying filter 38 and then enters the plate heat exchanger 32. After the coolant releases the heat on the battery side through the plate heat exchanger 32, it uses the power generated by the operation of the battery side water pump 22 to re-enter the end of the cycle and re-absorb the heat generated by the equipment.

[0027] The invention discloses a natural cooling and forced cooling hybrid dual-system liquid cooling air conditioning system, which is divided into a battery cooling part and an energy storage converter cooling part.

[0028] When the temperature sensed by the battery side water inlet temperature sensor 24 is low, the control board controls the electronic three-way valve 23 to close the plate heat exchanger 32, the compressor 34, and the microchannel condenser 36 channels. The battery side water pump 22 provides power, and the electronic three-way valve 23 is controlled to introduce the coolant in the battery side water inlet 20 into the natural cooler 24. The coolant dissipates heat through the natural cooler 24, and uses the power generated by the operation of the battery side water pump 22 to re-enter the end of the cycle and re-absorb the heat generated by the equipment.

[0029] When the temperature sensed by the battery side water inlet temperature sensor 24 is high, the coolant in the battery side water inlet 20 is introduced into the plate heat exchanger 32 by controlling the electronic three-way valve 23. The heat absorbed by the plate heat exchanger 32 from the coolant circulation system is absorbed by the evaporation of the liquid phase refrigerant. The refrigerant is compressed into high-temperature and high-pressure gas by the compressor 34 and enters the microchannel condenser 36. The heat is released into the surrounding air environment through the condensing fan 40 through the condensing of the refrigerant.

After the coolant releases the heat on the battery side through the plate heat exchanger 32, it uses the power generated by the operation of the battery side water pump 22 to re-enter the end of the cycle and re-absorb the heat generated by the equipment.

[0030] When the temperature sensed by the inverter side return water temperature sensor is low, the inverter side water pump 10 provides power to introduce the coolant in the inverter side water inlet 8 into the natural cooler 1. The coolant dissipates heat through the natural cooler 1, and uses the power generated by the operation of the inverter side water pump 10 to re-enter the end of the circulation and re-absorb the heat generated by the equipment.

[0031] When the temperature sensed by the return water temperature sensor on the inverter side is high, the coolant not only dissipates heat through the pipeline via the natural cooler 1, but the control panel opens the delivery pipe 14 by controlling the mixing stop valve 15, and the coolant in the battery side water outlet pipe 26 passes through the mixing stop valve 15 and remains in the inverter side water outlet pipe 13 to dissipate heat again, and uses the power generated by the operation of the inverter side water pump 10 to re-enter the circulation end and reabsorb the heat generated by the equipment.
