ABSTRACT:
Disclosed is a heat exchanger arranged such that a plurality of groups of cuttouts are formed on the surfaces of flat fins as between vertically adjacent heat transfer tubes by providing a plurality of cutouts, including two openings extending transverse to the direction of the air flow and two legs nonparallel with said direction of the air flow, on the front and reverse sides of the flat fins. This arrangement remarkably reduces the heat resistance between the air and the fin surfaces. Since the plurality of cutouts or the plurality of groups of cutouts are formed in the identical configuration, maintenance of a mold can be facilitated.
