Heat dissipation module

Abstract

A heat dissipation module comprises an aluminum cooling block and a copper base. The cooling block has a plurality of fins extending outward radially from the periphery of the cooling block. The base fits with the cooling block. A central recess is disposed at the bottom of the cooling block with at least an elongated through hole piercing the cooling block from the recess to the top of the cooling block. The base fits with the recess and has at least a support leg corresponding to the respective through hole to insert into the respective through hole. The heat dissipation module is less in cost and weight and enables the heat source to transmit to the fins of the cooling block rapidly and effectively.

1 . A heat dissipation module comprising:
 an aluminum cooling block with a plurality of fins extending outward radially from a periphery of said cooling block; and   a copper base fitting with said cooling block;   wherein, a central recess is disposed at the bottom of said cooling block to fit with said base, at least an elongated through hole pierces said cooling block from said recess to the top of said cooling block, at least a support leg extends outward from said base to correspond to the respective through hole such that said base is joined to said cooling block firmly in such a way of the respective support leg inserting into the respective through hole.   
   
   
       2 . The heat dissipation module as defined in  claim 1 , wherein the respective through hole has a periphery with a shape of circle, triangle, rectangle or polygon and the respective support leg has a cross-section with a shape corresponding to said periphery. 
   
   
       3 . The cooling fin as defined in  claim 1 , wherein the respective support leg is different from each in length.
