Generally, a cooling system of a gasoline vehicle requires a radiator for cooling the engine and a condenser for cooling the air-conditioner refrigerant, while the hybrid vehicle is equipped with a full-length radiator for cooling the electric device.

In addition to the engine that operates with a common fuel, the hybrid vehicle uses the electricity supplied from the electric battery to drive the motor to generate the driving force. Therefore, the heat generated from the battery and the motor must be effectively removed to secure the performance of the motor. .
