Abstract

A heat exchanger is provided with finned tubes (10) each fabricated by attaching fins (12) to a tube (11). Radial slits (13) are formed in a peripheral portion of the fin (12) to divide the peripheral portion into a plurality of segments. A portion of each of the segments is bent in an axial direction of the finned tube (10) along a bending line (14) extending from a point on the radial slit to form a plurality of bent portions (15). <IMAGE> <IMAGE>
