A heat exchanger utilizing a tube and fin core or a plate-fin separator wherein a plurality of tubes or plates are arranged in one or more rows with either corrugated fins between the tubes or a stack of horizontal split plate fins have openings receiving the tubes. The fins overhang the row or rows of tubes at the leading and/or trailing edges and have louvres formed therein, with the louvres in the overhanging portion being progressively shortened from the outer edge of the fin. In addition, the louvre at the leading and/or trailing edge of the fin is oriented substantially parallel to the fin surface and the direction of bulk air flow through the core.
