Abstract

The present invention provides a type of heat radiating fin, particularly one having multiple-face jutted snaps, said multiple-face jutted snaps are snapped to and pulled through matching snap holes provided on matching snap fold sides on the same heat-radiating fin, thereby to enhance high heat-radiating efficiency.

Claims

1. A type of heat-radiating fin, comprising of multilateral heat-radiating fin main unit having on a periphery thereof a specified number of snap fold sides, each snap fold side having at least one snap hole, at a front part of each snap hole being a multiple-face jutted snap.

2. The heat radiating fin of claim 1, wherein the multiple-face jutted snap is configured to have at least two faces, including three faces, four faces, a cylindrical shape, and other multiple-face geological shapes.

3. The heat radiating fin of claim 1, wherein the multiple-face jutted snap is snap joined and pulled through matching snap holes provided on matching snap fold sides on a same shape of heat-radiating fin, thereby forming a multiple-face turbulence jut.

4. The heat radiating fin of claim 2, wherein the multiple-face jutted snap is snap joined and pulled through matching snap holes provided on matching snap fold sides on a same shape of heat-radiating fin, thereby forming a multiple-face turbulence jut.
