Clip for heat sink

Abstract

A clip ( 30 ) securing a heat sink ( 10 ) includes a pair of spaced V-shaped main bodies ( 32 ) respectively received in grooves ( 16 ) of the heat sink. A pair of spaced wings ( 38 ) extends outwardly from opposite ends of each main body. The wings are slanted slightly upwardly. A hook ( 42 ) is formed at a free end of each wing. Each hook has a V-shaped profile. The wings are wider than the hooks, for facilitating manual operation of the clip.

What is claimed is:  
     
         1 . A clip adapted for securing a heat sink to a heat-generating device for removing heat therefrom, comprising: 
 a first main body adapted to be received in a groove of the heat sink, a pair of first wings extending outwardly from the main body, a first hook being formed at a free end of each of the first wings; and    a second main body adapted to be received in another groove of the heat sink, a pair of second wings extending outwardly from the main body, a second hook being formed at a free end of each of the second wings.    
     
     
         2 . The clip as described in  claim 1 , wherein the first and second main bodies both are substantially V-shaped.  
     
     
         3 . The clip as described in  claim 1 , wherein each of the first and second wings is slanted slightly upwardly.  
     
     
         4 . The clip as described in  claim 1 , wherein each of the first and second hooks is substantially V-shaped.  
     
     
         5 . The clip as described in  claim 4 , wherein the first wings are spaced from each other.  
     
     
         6 . The clip as described in  claim 5 , wherein the first wings are formed at opposite ends of the first main body.  
     
     
         7 . The clip as described in  claim 4 , wherein the second wings are spaced from each other.  
     
     
         8 . The clip as described in  claim 7 , wherein the second wings are formed at opposite ends of the second main body.  
     
     
         9 . The clip as described in  claim 1 , the clip further comprising at least one connecting portion between the first and second main bodies.  
     
     
         10 . The clip as described in  claim 1 , wherein the first wings are wider than the first hooks, and the second wings are wider than the second hooks, for facilitating manual operation of the clip.  
     
     
         11 . A heat sink assembly comprising: 
 a substrate supporting a heat-generating device thereon, the substrate defining a plurality of through holes therein;    a heat sink mounted on the heat-generating device, the heat sink comprising a base and a plurality of fins, the fins defining a plurality of grooves therebetween, a row of protrusions being formed on an inner row of the plurality of fins adjacent an inner groove of the plurality of grooves; and    a clip comprising a main body and a plurality of wings extending from the main body, the main body being deflectably received in said inner groove of the heat sink and pressing the heat sink against the heat-generating device, the wings being disposed at opposite sides of the heat sink, V-shaped hooks being formed on the wings and being engaged in the through holes of the substrate.    
     
     
         12 . A clip for use in a heat sink for securing the heat sink to a heat-generating electronic device, the clip comprising: 
 a pair of generally V-shaped main bodies adapted for fitting in two grooves defined in the heat sink, respectively;    a wing upwardly and outwardly extending from each of the main bodies; and    a generally V-shaped hook which is smaller than the wing extending downwardly from a distal end of the wing.    
     
     
         13 . The clip as described in  claim 12 , further comprising at least one connecting portion connecting the main bodies together.
