Heat dissipation fin for heat exchangers

Abstract

A heat dissipation fin for heat exchangers disposed between tubes for heat exchangers includes pluralities of louvers arranged in several layers. The louvers of the respective layers are inclined toward the middle of the heat dissipation fin in a straight line in a symmetrical fashion, and the distance between the louvers is gradually increased from the outermost end of a first half part of the heat dissipation fin to the middle of the heat dissipation fin, whereby the air resistance is decreased and the heat dissipation efficiency is improved.
