Radiation fin set for heat sink

Abstract

A radiation fin set comprising a plurality of metallic radiation fins arranged in parallel for direct welding/bonding to a beat dissipation base panel or mounting on a heat dissipation tube at the heat dissipation base panel, the radiation fins each having a plurality of elongated slots and a plurality of flanges respectively extended along one side of each of the elongated slots and sloping in one direction at an angle of slope for guiding the flow of air of high momentum into mixing with the flow of air of low momentum to repress the formation of boundary layer and to improve heat dissipation efficiency of the radiation fins.

What the invention claimed is:  
     
         1 . A radiation fin set comprising a plurality of metallic radiation fins arranged in parallel, said radiation fins each having a plurality of elongated slots and a plurality of flanges respectively extended along one side of each of said elongated slots and sloping in one direction at an angle of slope.  
     
     
         2 . The radiation fin set of  claim 1  wherein said radiation fins each have a through hole respectively aligned for mounting.  
     
     
         3 . The radiation fin set of  claim 1  wherein the angle of slope of said flanges is 30°.  
     
     
         4 . The radiation fin set of  claim 1  wherein said flanges each have at least one air vent for the passing of air.
