Abstract
A condenser core portion carries out a heat exchange between refrigerant and air. The condenser core portion includes a plurality of condenser tubes through which the refrigerant flows and condenser fins disposed between each pair of adjacent condenser tubes. A radiator core portion is disposed in series with the condenser core portion in an external fluid flow direction with a predetermined clearance therebetween, to carry out a heat exchange between engine coolant and the air. The radiator core portion includes a plurality of radiator tubes through which the engine coolant flows and radiator fins disposed between each pair of adjacent radiator tubes. A connecting portion integrates each of condenser fins and radiator fins. The condenser fins disposed at an upper area of the condenser core portion introduce cooling performances more than the condenser fins disposed at a lower area thereof.
