Combination fin and heat pipe assembly

Abstract

A combination fin and heat pipe assembly includes a heat pipe, and a plurality of radiation fins each including a fin plate, a mounting through hole in the fin plate that receives the heat pipe, an annular flange extending from one side of the fin plate around the mounting through hole and two opposing arched slots each cut through a part of the fin plate adjacent to a peripheral wall of the annular flange to partially separate the annular flange from the respective fin plate. The annular flange has the peripheral wall deformed on two opposite sides corresponding to the arched slots and forced into tight engagement with the periphery of the heat pipe.

What is claimed is: 
     
         1 . A combination fin and heat pipe assembly, comprising:
 a heat pipe; and   a plurality of radiation fins mounted on said heat pipe arranged in parallel, each said radiation fin comprising a fin plate, a mounting through hole in said fin plate for receiving said heat pipe, an annular flange extending from one side of said fin plate around said mounting through hole, and two opposing arched slots each cut through a part of said fin plate immediately adjacent to a peripheral wall of said annular flange to partially separate said annular flange from said fin plate, wherein the peripheral wall of said annular flange is partially deformed and forced into tight engagement with the periphery of said heat pipe.   
     
     
         2 . The combination fin and heat pipe assembly as claimed in  claim 1 , wherein the peripheral wall of said annular flange of each said radiation fin around said mounting through hole and the periphery of said heat pipe are symmetrically and equally deformed on two opposite sides and forced into tight engagement with each other. 
     
     
         3 . The combination fin and heat pipe assembly as claimed in  claim 1 , wherein the peripheral wall of said annular flange of each said radiation fin around said mounting through hole and the periphery of said heat pipe are flattened on two opposite sides and forced into tight engagement with each other. 
     
     
         4 . The combination fin and heat pipe assembly as claimed in  claim 1 , wherein the peripheral wall of said annular flange of each said radiation fin around said mounting through hole and the periphery of said heat pipe are inwardly curved on two opposite sides and forced into tight engagement with each other. 
     
     
         5 . The combination fin and heat pipe assembly as claimed in  claim 1 , wherein said heat pipe is a round pipe. 
     
     
         6 . The combination fin and heat pipe assembly as claimed in  claim 1 , wherein said heat pipe is a flat oval pipe.
