ABSTRACT:
A heat exchanger having a plurality of tubes for circulating a refrigerant fluid and a plurality of fins in heat exchange contact with the plurality of tubes. Each of the fins includes a plurality of aligned collars defining at least one row of longitudinally spaced apertures, the plurality of tubes extending through the apertures and engaged by the collars. A pair of reinforcing ribs extend longitudinally of the fin, one of the pair on each side of the at least one row of apertures. A plurality of longitudinally spaced flat portions, lying in a common plane, and extend transversely between the ribs, one of the flat portions circumscribing each of the collars. A plurality of central corrugated portions transversely spaced from the ribs, extend longitudinally, one of the corrugated portions lying between each two of the flat portions. At least two sets of longitudinally extending louvers are located transversely between the central corrugated portion and the ribs and longitudinally between the flat portions.
