Abstract
A heat exchanger assembly (10) includes a pair of tanks (16, 18) with a plurality of flat-sided fluid tubes (20) extending between the tanks (16, 18). Fins (22) may be located externally between adjacent fluid tubes (20), and may be located internally within each fluid tube (20) for increasing heat exchange. The fins (22) are formed by a plurality of undulations (32) establishing lengths of walls (34) between peaks (36) of the undulations (32). The walls (34) include a plurality of slits (44) therein forming panels (42) between adjacent slits (44). The panels (42) are 'randomly' deformed of various contours to extend at various distances from the walls (34) to increase heat exchange.
