Heat dissipating device and method of manufacturing the same

Abstract

A heat dissipating device includes a base, a heat pipe and a fixing member. The base includes an accommodating recess and two restraining portions, wherein the two restraining portions are located at opposite sides of the accommodating recess and an opening is between the two restraining portions. A first end of the heat pipe is disposed in the accommodating recess such that a bottom surface of the first end is exposed out of the opening, wherein a width of the opening is smaller than a maximum width of the first end. The fixing member is disposed on the base such that the first end of the heat pipe is fixed between the fixing member and the two restraining portions.

What is claimed is: 
     
         1 . A heat dissipating device comprising:
 a base comprising an accommodating recess and two restraining portions, the two restraining portions being located at opposite sides of the accommodating recess, an opening being between the two restraining portions;   a heat pipe, a first end of the heat pipe being disposed in the accommodating recess such that a bottom surface of the first end is exposed out of the opening, a width of the opening being smaller than a maximum width of the first end; and   a fixing member disposed on the base such that the first end of the heat pipe is fixed between the fixing member and the two restraining portions.   
     
     
         2 . The heat dissipating device of  claim 1 , wherein the bottom surface of the first end and a bottom surface of the base are coplanar. 
     
     
         3 . The heat dissipating device of  claim 1 , wherein the base further comprises a first half portion, a second half portion and at least one rib, the accommodating recess is formed between the first half portion and the second half portion, and the at least one rib connects the first half portion and the second half portion. 
     
     
         4 . The heat dissipating device of  claim 3 , wherein the at least one rib and the fixing member are located at one side of the base. 
     
     
         5 . The heat dissipating device of  claim 3 , wherein the at least one rib and the fixing member are located at opposite sides of the base. 
     
     
         6 . The heat dissipating device of  claim 1 , wherein a surface of each of the two restraining portions, which contacts the first end of the heat pipe, is an arc surface or an oblique surface. 
     
     
         7 . The heat dissipating device of  claim 1  further comprising a heat sink disposed on a second end of the heat pipe. 
     
     
         8 . The heat dissipating device of  claim 1 , wherein the heat pipe is a flat heat pipe. 
     
     
         9 . A method of manufacturing a heat dissipating device comprising:
 forming a base by a die casting process, wherein the base comprises an accommodating recess;   disposing a first end of a heat pipe in the accommodating recess;   disposing a fixing member on the base so as to fix the first end of the heat pipe in the accommodating recess; and   milling a bottom surface of the base so as to form an opening at one side of the accommodating recess such that a bottom surface of the first end is exposed out of the opening, wherein a width of the opening is smaller than a maximum width of the first end.   
     
     
         10 . The method of  claim 9 , wherein the bottom surface of the first end and the bottom surface of the base after milling are coplanar. 
     
     
         11 . The method of  claim 9 , wherein the base further comprises a first half portion, a second half portion and at least one rib, the accommodating recess is formed between the first half portion and the second half portion, and the at least one rib connects the first half portion and the second half portion. 
     
     
         12 . The method of  claim 11 , wherein the at least one rib and the fixing member are located at one side of the base. 
     
     
         13 . The method of  claim 11 , wherein the at least one rib and the fixing member are located at opposite sides of the base. 
     
     
         14 . The method of  claim 9 , wherein the opening is between two restraining portions, and a surface of each of the two restraining portions, which contacts the first end of the heat pipe, is an arc surface or an oblique surface. 
     
     
         15 . The method of  claim 9  further comprising:
 disposing a heat sink on a second end of the heat pipe. 
 
     
     
         16 . The method of  claim 9 , wherein the heat pipe is a flat heat pipe.
