ABSTRACT:
A heat exchanger (10) includes a pair of manifolds (12, 14) interconnected by a core member having a plurality of fluid tubes (20) extending between manifolds (12, 14) and fins (22) connected between adjacent fluid tubes (20). The fin (22) is comprised of a corrugated sheet of material forming peaks connected to the tubes (20) with fin walls (34) extending between peaks. Alternating walls (34) of the fin (22) are comprised of an uninterrupted section (40) and a louvered section (42). The uninterrupted section (40) is defined by either a sinusoidal wave of continuous sheet or straight section deformed into the wall (34). The louvered section (42) is defined by a plurality of louvers (46) interrupting and cut into the sheet formed in the wall (34) providing air gaps.
