A condenser for a vehicle is used in an air conditioning having an expansion valve, an evaporator, and a compressor, is provided between the compressor and the expansion valve, and circulates coolant supplied from a radiator so as to condense refrigerant supplied from the compressor through heat-exchange with the coolant and the refrigerant.
The condenser may include a main heat-radiating portion connected to the radiator to circulate coolant, and adapted to circulate refrigerant from the compressor to condense the refrigerant through heat-exchange with the coolant, a receiver-drier portion integrally formed with the main heat-radiating portion to receive the condensed refrigerant perform gas-liquid separation and moisture removal of the refrigerant, and an overcooling heat-radiating portion circulating low temperature and low pressure gas refrigerant supplied from the evaporator, and overcooling the refrigerant supplied from the receiver-drier portion through heat-exchange with the low temperature and low pressure gas refrigerant.
