Heat-dissipating fins

Abstract

The present invention relates to a heat sink of a large area, in which a heat-dissipating body is further provided in its limited space. The method for manufacturing a fin includes the steps of providing a fin, cutting the fin to form a foldable piece thereon, folding back the foldable piece to be overlapped on the fin and form an accommodating hole, and punching the folded piece and the fin to form two overlapped through-holes. The fin, the heat-dissipating body and heat pipes are assembled together to obtain the heat sink. Since the fins and the heat-dissipating body dissipate the heat of a heat-generating element simultaneously, the heat-dissipating efficiency of the heat sink can be improved.

What is claimed is: 
     
         1 . A plurality of heat-dissipating fins, comprising a plurality of fins parallel to each other and arranged at intervals, a heat pipe penetrating the fins, the fin being provided with a foldable piece, the foldable piece being folded back to be overlapped on the fin, thereby forming an accommodating hole on the fin, the folded piece and the fin being provided with two overlapped through-holes, the heat pipe penetrating the two through-holes of the fin. 
     
     
         2 . The heat-dissipating fins according to  claim 1 , wherein the peripheries of the two through-holes are provided with two overlapped flanges, the flange of the fin is adhered to an outer wall of the heat pipe tightly. 
     
     
         3 . The heat-dissipating fins according to  claim 1 , further comprising a heat-dissipating body, the heat-dissipating body being disposed in the accommodating holes of the fins. 
     
     
         4 . The heat-dissipating fins according to  claim 1 , further comprising a heat-conducting base, the heat-conducting base allowing the heat pipe to be inserted therein.
