Cooling fin assembly

Abstract

A cooling fin assembly provides a plurality of cooling fins and each of the cooling fins has a cooling fin body with at least a recess part indenting toward a side thereof. The recess part has an insert space with a through hole slightly less than the entire area of the recess part for being passed through with a heat guide pipe. Further, a folded side surrounds the through hole and extending toward the side. Once a heat guide medium, which is inserted between the through hole and the heat guide pipe, is heated up to become in a state of melting during being set up, the molten heat guide medium distributes between the outer surface of the heat guide pipe and the through hole and over the folded side evenly.

1 . A cooling fin assembly, comprising: 
 a plurality of cooling fins, each of the cooling fins having a cooling fin body with at least a recess part indenting toward a side thereof, the recess part having an insert space with a through hole slightly less than the entire area of the recess part and a folded side surrounding the through hole and extending toward the side; and    a heat guide pipe, passing through the through hole.    
   
   
       2 . The cooling fin assembly as defined in  claim 1 , wherein the inner wall surface of the through hole is greater than the outer surface of the heat guide pipe and a clearance is formed between the folded side and the outer surface of the heat guide pipe.  
   
   
       3 . The cooling fin assembly as defined in  claim 1 , wherein the inner wall surface of the through hole contact with the outer surface of the heat guide pipe and the folded side contacts with the outer surface of the heat guide pipe completely too.  
   
   
       4 . The cooling fin assembly as defined in  claim 1 , wherein the insert space has a heat conductive medium.  
   
   
       5 . The cooling fin assembly as defined in  claim 1 , wherein the heat conductive medium is a tin paste.  
   
   
       6 . The cooling fin assembly as defined in  claim 1 , wherein the insert space provides a shape of circle, semi-cone or countersink or any shapes.  
   
   
       7 . The cooling fin assembly as defined in  claim 1 , wherein the perimeter of the insert space is greater than the outer surface of the heat guide pipe.
