Heat dissipation device

Abstract

A heat dissipation device includes a plate, a protrusion to divide a top of the plate into a number of mounting areas, and a number of heat sinks selectively received on the number of mounting areas.

1 . A heat dissipation device comprising:
 a plate;   a protrusion protruding from a top of the plate to divide the top of the plate into a plurality of mounting areas; and   a plurality of heat sinks separately and selectively mounted to the plurality of mounting areas of the plate.   
     
     
         2 . The heat dissipation device of  claim 1 , wherein each of the plurality of heat sinks comprises a base and a plurality of fins extending from the base. 
     
     
         3 . The heat dissipation device of  claim 2 , wherein a fixing hole is defined in the base of each of the plurality of heat sinks, a locking hole is defined in each of the mounting areas, corresponding to the fixing hole, and a fastener passes through the fixing hole of a heat sink to engage the locking hole of a corresponding mounting area, to fix the heat sink onto the plate. 
     
     
         4 . The heat dissipation device of  claim 2 , wherein a shape of the base of each of the heat sinks is same as that of the corresponding mounting area of the plate. 
     
     
         5 . The heat dissipation device of  claim 2 , wherein heights of the plurality of fins of each heat sink differ from those of the plurality of fins of another heat sink. 
     
     
         6 . The heat dissipation device of  claim 1 , wherein the protrusion is cross-shaped to divide the top of the plate into four mounting areas to selectively receive four heat sinks on the plate. 
     
     
         7 . The heat dissipation device of  claim 6 , further comprising a clip, wherein two pairs of tabs extend perpendicular from the protrusion, and two tabs each pair of tabs are opposite to each other, with a latching portion formed between the tabs to hold the clip.
