Radial heat sink with heat pipe set therein

Abstract

A radial heat sink includes a hollow core base with mounting grooves axially located on the inside wall thereof and a locating groove located on an end wall at one end thereof, radiation fins arranged around the periphery of the hollow core base, and heat pipes inserted through the end wall of the hollow core base and press-fitted into the mounting grooves and the locating groove and kept in flush with the end wall of the hollow core base.

1 . A radial heat sink, comprising:
 a hollow core base having a top end and a bottom end and at least one locating groove located on said bottom end;   a plurality of radiation fins arranged around the periphery of said hollow core base; and   at least one heat pipe mounted in said hollow core base, each said heat pipe having at least one part thereof press-fitted in one said locating groove and kept in flush with an outer surface of the bottom end of said hollow core base.   
     
     
         2 . The radial heat sink as claimed in  claim 1 , wherein said hollow core base comprises at least one mounting groove axially extending along an inside wall thereof for receiving said at least one heat pipe. 
     
     
         3 . The radial heat sink as claimed in  claim 2 , wherein said hollow core base comprises an end wall located on said bottom end, and at least one through hole cut through said end wall in communication with said at least one locating groove for the passing of said at least one heat pipe. 
     
     
         4 . The radial heat sink as claimed in  claim 3 , wherein said at least one locating groove is located on an outer surface of said end wall. 
     
     
         5 . The radial heat sink as claimed in  claim 4 , wherein said hollow core base further comprises a plurality of mounting holes cut through said end wall for mounting. 
     
     
         6 . The radial heat sink as claimed in  claim 4 , wherein each said heat pipe has a flat outer surface kept in flush with the outer surface of said end wall. 
     
     
         7 . The radial heat sink as claimed in  claim 1 , wherein each said heat pipe has a U-shaped profile. 
     
     
         8 . The radial heat sink as claimed in  claim 1 , wherein each said heat pipe has an L-shaped profile. 
     
     
         9 . The radial heat sink as claimed in  claim 1 , wherein each said heat pipe is a straight heat pipe. 
     
     
         10 . The radial heat sink as claimed in  claim 1 , wherein each said heat pipe has an arched profile. 
     
     
         11 . The radial heat sink as claimed in  claim 1 , wherein said hollow core base further comprises at least one rib extending along at least one of two opposite lateral sides of each said locating groove, each said rib being deformable to clamp one said heat pipe in one said locating groove. 
     
     
         12 . The radial heat sink as claimed in  claim 2 , wherein said hollow core base further comprises a plurality of ribs extending along at least one of two opposite lateral sides of each said locating groove and each said mounting groove, each said rib being deformable to clamp one said heat pipe in one said locating groove or one said mounting groove. 
     
     
         13 . The radial heat sink as claimed in  claim 3 , further comprising annular packing plate fastened to the bottom end of said core base and stopped against a bottom edge of each of said radiation fins and kept in flush with the outer surface of said end wall and a flat outer surface of each said heat pipe.
