Cooler module

Abstract

A cooler module formed of a heat sink and a cooling fan is disclosed. A heat receiving base member of the heat sink has a flat bottom center contact surface and a plurality of bottom sloping surfaces (or one tapered bottom surface) obliquely upwardly extended from the border of the flat bottom center contact surface to the border of the heat receiving base member for spreading heat in all directions rapidly and evenly.

1 . A cooler module comprising a heat sink, said heat sink comprising a heat receiving base member for attaching to a heat source on a circuit board to transfer heat from said heat source and a plurality of radiation fins for dissipating heat from said heat receiving base member, wherein said heat receiving base member comprises a top wall supporting said radiation fins and a bottom wall opposite to said top wall, said bottom wall comprising a flat contact surface for direct contact with said heat source and at least one sloping surface obliquely upwardly extending from the border of said flat contact surface to the border of said heat receiving base member. 
   
   
       2 . The cooler module as claimed in  claim 1 , wherein said heat receiving base member comprises a plurality of mounting through holes cut through said top wall and said bottom wall in corners thereof for mounting fastening members. 
   
   
       3 . The cooler module as claimed in  claim 1 , wherein said heat receiving base member comprises two eye lugs protruded from two distal ends of a second lateral side thereof and each said eye lug has a through hole. 
   
   
       4 . The cooler module as claimed in  claim 3 , wherein said heat receiving base member further comprises a flange protruded from a first lateral side thereof opposite to said second lateral side, and two beveled edges formed on two distal ends of said first lateral side and two distal ends of said flange. 
   
   
       5 . The cooler module as claimed in  claim 1 , wherein said flat contact surface is a flat rectangular surface. 
   
   
       6 . The cooler module as claimed in  claim 1 , wherein said flat contact surface is a flat circular surface. 
   
   
       7 . The cooler module as claimed in  claim 1 , wherein said flat contact surface is a flat rhombic surface. 
   
   
       8 . The cooler module as claimed in  claim 1 , wherein said heat receiving base member is made from a metal material by means of one of the techniques of extrusion, die casting and forging. 
   
   
       9 . The cooler module as claimed in  claim 8 , wherein said metal material is selected from the group of aluminum, copper and their alloys. 
   
   
       10 . The cooler module as claimed in  claim 1 , further comprising a cooling fan mounted on said radiation fins at a top side. 
   
   
       11 . The cooler module as claimed in  claim 1 , further comprising a cooling fan provided at one side relative to said radiation fins.
