PURPOSE: To make cooling air strike directly on a subcooling part 884 of tubes and thereby to make a condenser taking subcooling display its capacity to the full by disposing receiver tubes at the upper and lower ends of a heat exchanger part on which the cooling air hardly strikes and also by disposing the subcooling part on the upstream side of the cooling air.

CONSTITUTION: A heat exchanger part is constructed by providing corrugate fins 3 between a plurality of tubes 2, while inlet-side and outlet-side headers 5 and 6 are connected to the opposite ends of each tube 2 respectively. Each tube 2 is a flat tube having a number of refrigerant passages formed inside, while the tubes are divided into a plurality of tube groups constituting a main condenser part 2a and a subcooling part 2b of a refrigerant. Moreover, the main condenser part 2a and the subcooling part 2b are so disposed as to be sectioned on the upstream and downstream sides of cooling air. At the lower end of the heat exchanger part 4, a receiver tube 9 having a larger passage area than the one of a refrigerant piping is provided. By making the cooling air strike directly on the subcooling part 2b, according to this constitution, the performance thereof is improved and a condenser taking subcooling is made to display its capacity to the full.
