Heat spreader

Abstract

A heat spreader that includes a body member, a first fin connected to the body member, a second fin connected to the body member, a third fin connected to the body member, and a fourth fin connected to the body member. The first and second fins define a first spacing therebetween. The second and third fins define a second spacing therebetween. The third and fourth fins define a third spacing therebetween. The second spacing is greater than the first spacing and the third spacing.

1 . A heat spreader, comprising: 
 a body member;    a first fin connected to the body member;    a second fin connected to the body member, wherein the first and second fins define a first spacing therebetween;    a third fin connected to the body member, wherein the second and third fins define a second spacing therebetween, and wherein the second spacing is greater than the first spacing; and    a fourth fin connected to the body member, wherein the third and fourth fins define a third spacing, and wherein the second spacing is greater than the third spacing.    
     
     
         2 . The heat spreader of  claim 1 , wherein the heat spreader is fabricated from a metal.

         4 . The heat spreader of  claim 1 , wherein the first, second, third and fourth fins are integrally formed with the body member.  
     
     
         5 . The heat spreader of  claim 1 , wherein the body member includes a first mounting tab and a second mounting tab.  
     
     
         6 . The heat spreader of  claim 5 , wherein the first mounting tab defines a first mounting hole and the second mounting tab defines a second mounting hole.  
     
     
         7 . The heat spreader of  claim 1 , wherein: 
 the body member includes a first surface and a second surface opposite the first surface;    the first fin is connected to the first surface of the body member proximate a first end of the body member;    the second fin is connected to the first surface of the body member adjacent the first fin;    the third fin is connected to the first surface of the body member adjacent the second fin; and    the fourth fin is connected to the first surface of the body member adjacent the third fin and proximate a second end of the body member.    
     
     
         8 . The heat spreader of  claim 7 , wherein: 
 the first fin includes: 
 a first face proximate the first end of the body member; and  
 a second face opposite the first face;  
   the second fin includes: 
 a first face adjacent the second face of the first fin; and  
 a second face opposite the first face of the second fin;  
   the third fin includes: 
 a first face adjacent the second face of the second fin; and  
 a second face opposite the first face of the third fin; and  
   the fourth fin includes: 
 a first face adjacent the second face of the third fin; and  
 a second surface opposite the first face of the fourth fin.  
   
     
     
         9 . The heat spreader of  claim 8 , wherein: 
 the first and second faces of the first fin are substantially perpendicular to the second surface of the body member;    the first and second faces of the second fin are substantially perpendicular to the second surface of the body member;    the first and second faces of the third fin are substantially perpendicular to the second surface of the body member; and    the first and second faces of the fourth fin are substantially perpendicular to the second surface of the body member.    
     
     
         10 . The heat spreader of  claim 9 , wherein the first and second faces of the first fin are substantially parallel to: 
 the first and second faces of the second fin;    the first and second faces of the third fin; and    the first and second faces of the fourth fin.    
     
     
         11 . The heat spreader of  claim 8 , wherein: 
 the second face of the first fin has a first cross-sectional area;    the first face of the second fin has a second cross-sectional area; and    the second face of the second fin has a third cross-sectional area, wherein the third cross-sectional area is greater than the second cross-sectional area.    
     
     
         12 . The heat spreader of  claim 11 , wherein the second cross-sectional area is greater than the first cross-sectional area.  
     
     
         13 . The heat spreader of  claim 12 , wherein: 
 the first face of the third fin has a fourth cross-sectional area;    the second face of the third fin has a fifth cross-sectional area;    the first face of the fourth fin has a sixth cross-sectional area, wherein the fifth cross-sectional area is greater than the sixth cross-sectional area.    
     
     
         14 . The heat spreader of  claim 13 , wherein the fourth cross-sectional area is greater than the fifth cross-sectional area.  
     
     
         15 . The heat spreader of  claim 14 , wherein: 
 the first cross-sectional area is substantially equivalent to the sixth cross-sectional area;    the second cross-sectional area is substantially equivalent to the fifth cross-sectional area; and    the third cross-sectional area is substantially equivalent to the fourth cross-sectional area.    
     
     
         16 . The heat spreader of  claim 8 , wherein the second face of the first fin defines a first groove.
