Abstract
A flat tube and fin heat exchanger comprises a plurality of tubes arranged in spaced parallelism and a plurality of louvered fins are located between each of the tubes in heat exchange relationship with the tubes. The fins are formed as a series of sinusoidal corrugations defining axial air flow passages in a direction generally transverse to the longitudinal axes of the tubes. A predetermined series of fin panels have louvers formed therein to create turbulence in the axial air flow through the fins. A second series of fin panels are dammed to channel air flow through the tubes so as to maximize heat transfer characteristics of the heat exchanger.
