A heat exchanger having a flow of air therethrough adapted for use in refrigeration systems includes a heat exchange coil and a plurality of sheet-like fins. The coil is formed of a plurality of tubes having a cooling medium flowing therethrough. Each of the fins are provided with openings for receiving the tubes in heat transfer relationship. A plurality of tabs are arranged in a surrounding relationship around the lower portion of the openings on the tubes for preventing the blow-off of condensate drops forming on the underneath side of the tubes.

A fin and coil type evaporator assembly positionable in a vertically, upwardly flowing air stream comprising: an evaporator coil including a plurality tube sections extending transversely to the direction of air flow; a plurality of plate-like fins closely spaced apart, each fin lying in a plane parallel to the direction of air flow and being in heat exchange contact with said tube sections which pass through said fins; and means defining a plurality of channels, elongated in the direction of air flow and located closely adjacent to said tube sections only on the up-stream side thereof, said channels being adapted to break up and draw off, by capillary action, large droplets of water condensing on said tube sections and adhering to the underside thereof, whereby blow-off of condensate from the tubes is minimized.
