ABSTRACT:
A fin for use in a heat exchanger of the type comprising a plurality of fluid carrying tubes for transporting heat exchange fluid is disclosed. The fin includes a generally planar base 24 having a longitudinal axis generally perpendicular to the direction of air flowing entering the heat exchanger 10 and a transverse axis generally parallel to the direction of air flow. The axes define a main plane disposed at a predetermined angle (.theta.) relative to the direction of air flow entering the heat exchanger. The fin 22 further includes a plurality of apertures 30 for receiving tubes 20 therethrough and a plurality of louvres 32 disposed on the base 24 extending generally parallel to the longitudinal axis of the base. The angle .theta. can be between 140 and 175 degrees to the direction of air flow entering the heat exchanger.
