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 the heat-generating element simultaneously, the heat-dissipating efficiency of the heat sink can be improved.
