Heat dissipating device and method of manufacture thereof

Abstract

A heat dissipating device and a method of fabricating thereof, the device comprising a first base adapted to be placed in contact with a heat emitter and first heat-dissipating fins extending from the first base on at least part of a periphery of the first base. The method comprises providing a first sheet of heat conductive and mechanically resistant material; cutting, out of the first sheet of material, a first piece comprising a first central part and first tabs extending radially from the first central part; and erecting the first tabs up from the first central part.

1 . A heat dissipating device, comprising a first base adapted to be placed in contact with a heat emitter and first heat-dissipating fins extending from said first base on at least part of a periphery of said first base. 
     
     
         2 . The heat dissipating device of  claim 1 , wherein said first heat-dissipating fins extend from said first base at a first angle. 
     
     
         3 . The heat dissipating device of  claim 1 , wherein said first heat-dissipating fins extend from said first base on at least part of a periphery of said first base, a main surface of said first base remaining free of said first fins. 
     
     
         4 . The heat dissipating device of  claim 1 , wherein said first base and said first fins are made from a metal sheet. 
     
     
         5 . The heat dissipating device of  claim 1 , comprising a second base adapted to be placed in contact with said first base and second heat-dissipating fins extending from at least part of a periphery of said second base at a second angle. 
     
     
         6 . The heat dissipating device of  claim 1 , wherein said first base comprises holes therein. 
     
     
         7 . The heat dissipating device of  claim 5 , wherein said second base comprises holes therein. 
     
     
         8 . The heat dissipating device of  claim 5 , wherein at least one of said first and said second bases comprises holes therein. 
     
     
         9 . A method of fabricating a heat dissipating device, comprising:
 providing a first sheet of heat conductive and mechanically resistant material;   cutting, out of the first sheet of material, a first piece comprising a first central part and first tabs extending radially from the first central part; and   erecting the first tabs up from the first central part.   
     
     
         10 . The method of  claim 9 , wherein said erecting the first tabs up from the first central part comprises folding the first tabs up away from the first central part at a first angle. 
     
     
         11 . The method of  claim 9 , wherein said providing a first sheet comprises providing a sheet comprising aluminum. 
     
     
         12 . The method of  claim 9 , further comprising positioning the heat dissipating device with the first central part in contact with a heat emitter, the first tabs extending up from the perimeter of the first central part away from the heat emitter. 
     
     
         13 . The method of  claim 9 , further comprising:
 providing a second sheet of heat conductive and mechanically resistant material;   cutting, out of the second sheet of material, a second piece comprising a second central part and second tabs extending radially from the second central part;   erecting the second tabs up from the second central part;   placing said first central part in contact with a heat emitter, said first tabs extending from said first central part on at least part of a periphery of said first central part; and   placing said second central part in contact with said first central part, said second tabs extending from said second central part on at least part of a periphery of said second central part.   
     
     
         14 . The method of  claim 9 , further comprising providing holes in the first central part. 
     
     
         15 . The method of  claim 9 , further comprising:
 providing a second sheet of heat conductive and mechanically resistant material;   cutting, out of the second sheet of material, a second piece comprising a second central part and second tabs extending radially from the second central part;   providing holes in at least one of the first central part and the second central part;   erecting the second tabs up from the second central part;   placing said first central part in contact with a heat emitter, said first tabs extending from said first central part on at least part of a periphery of said first central part; and   placing said second central part in contact with said first central part, said second tabs extending from said second central part on at least part of a periphery of said second central part.
