ABSTRACT:
The present invention is directed to an evaporator for an automotive air conditioning refrigeration circuit. The evaporator includes a serpentined tube through which refrigerant fluid flows, and a corrugated metal fin unit fixedly disposed between parallel planar portions of the serpentined tube. A plurality of louvers are formed through the parallel surfaces of the corrugated metal fin units. The side ends of the louvers terminate a predetermined distance away from the surfaces of the parallel planar portions of the tube. The distance is selected from a range of from over 0.5 mm to under 1.0 mm.
