When the circulation pump is driven, the cooling water in the connection tube flows to the cooling water tube, absorbs the heat of the battery in the cooling water tube, and is then transferred to the radiator. The cooling water transferred to the radiator can dissipate heat to the air blown to the radiator. That is, the cooling water circulates the cooling water tube and the radiator and can dissipate the battery.

 The refrigerant-type battery cooling apparatus includes a compressor for compressing a refrigerant, a condenser for condensing the refrigerant compressed in the compressor, an expansion valve for expanding the refrigerant condensed in the condenser, a refrigerant expanded by the expansion valve, Battery module heat exchanger.

When the compressor is driven, the refrigerant compressed in the compressor can be sucked into the compressor after sequentially passing through the condenser, the expansion valve, and the battery heat exchanger, and the refrigerant can absorb the heat of the battery module while passing through the battery heat exchanger.
