The evaporator includes the upper side and lower header membersanddisposed at the upper and lower end of the core. One end of each tubeconstituting the upstream-side tube group Pis connected to the inlet-side tank, while the other end to the lower header member. One end of each tubeconstituting the downstream-side tube group Pis connected to the outlet-side tank, while the other end to the lower header member. The refrigerant flowed into the inlet-side tankis introduced into the outlet-side tankby passing through the upstream-side tube group P, the lower header memberand the downstream-side tube group P, so that the refrigerant evaporates by exchanging heat with ambient air A. Accordingly, it improves the heat exchange performance and decreases the thickness.

This duplex-type heat exchanger is adapted to a vapor compression type refrigeration cycle in which a condensed refrigerant is decompressed and then evaporated. This duplex-type heat exchanger is integrally equipped with a subcooler S in which the condensed refrigerant exchanges heat with the ambient air A to be subcooled and an evaporator E in which the decompressed refrigerant exchanges heat with the ambient air A to be evaporated. Heat exchange is performed between the refrigerant passing through the subcooler S and the refrigerant passing through the evaporator E, to thereby cool the refrigerant in the subcooler S and heat the refrigerant in the evaporator E. Accordingly, according to this heat exchanger, a high refrigeration effect can be obtained while avoiding the pressure rise of the refrigerant.
