Abstract
The present invention relates to a louvered heat transfer fin in which the air-passing resistance of the louver is varied so as to increase the overall heat exchange quantity, and thereby to greatly enhance the heat transfer performance of the fin. The arrangement of each louver is such that the projection area in the vicinity of the longitudinal central portion of the louver projected in the direction in which air passes is larger than the projection area of each of the longitudinal end sides of the louver projected in the same direction.
