Heat dissipation module

Abstract

A heat dissipation module including a heat sink, a thermal medium, and a thermal medium cap is provided. The heat sink is suitable to be disposed on a heat source, and the heat sink has a plurality of grooves. The thermal medium is disposed on a surface of the heat sink contacting the heat source. In addition, the thermal medium cap has a cover and a plurality of fixing portions extending from the cover. The thermal medium is covered by the cover, and the fixing portions penetrate the grooves.

What is claimed is: 
     
         1 . A heat dissipation module, comprising:
 a heat sink, suitable to be disposed on a heat source, wherein the heat sink has a plurality of grooves;   a thermal medium, disposed on a surface of the heat sink contacting the heat source; and   a thermal medium cap, having a cover and a plurality of fixing portions extending from the cover, wherein the thermal medium is covered by the cover, and the fixing portions penetrate the grooves.   
     
     
         2 . The heat dissipation module as claimed in  claim 1 , wherein the cover comprises a top wall and a side wall, and the top wall and the side wall constitute a covering space for covering the thermal medium. 
     
     
         3 . The heat dissipation module as claimed in  claim 1 , wherein the cover and the fixing portions are integrated into one piece. 
     
     
         4 . The heat dissipation module as claimed in  claim 1 , wherein the material of the thermal medium cap is a plastic material. 
     
     
         5 . The heat dissipation module as claimed in  claim 1 , wherein the heat sink comprises a seat suitable to contact the heat source, and the thermal medium is disposed on a surface of the seat contacting the heat source. 
     
     
         6 . The heat dissipation module as claimed in  claim 5 , wherein the grooves are located at the side edges of the seat. 
     
     
         7 . The heat dissipation module as claimed in  claim 5 , wherein the heat sink further comprises a fin set and a plurality of heat pipes, one end of each of the heat pipes is connected to the seat, and the fin set is disposed at the other end of each of the heat pipes. 
     
     
         8 . The heat dissipation module as claimed in  claim 7 , wherein the heat sink further comprises a locking bracket connected to the seat, and the heat pipes are clamped between the locking bracket and the seat. 
     
     
         9 . The heat dissipation module as claimed in  claim 8 , wherein the grooves are located at the side edges of the locking bracket.
