Abstract

A fin of a heat exchanger is provided to increase heat transfer efficiency of refrigerants with outdoor air or indoor air by installing plural micro projection parts shaped like one of triangle, rectangle, and hemisphere. A fin of a heat exchanger comprises a collar(12) where a refrigerant tube is passed, and a plurality of micro projection parts(11), which is formed at least one of the front surface and the back surface with predetermined intervals, penetrating the refrigerant tube. The micro projection parts have sections which are shaped like one of triangle, rectangle, and hemisphere types. The micro projection parts are also shaped in parallel with flow direction of air. Consequently, the flowing resistance of air is minimized by forming the micro projection parts with the flow direction of air inside the fin of the heat exchanger in parallel.
