Heat dissipation module

Abstract

A heat dissipation module includes a plurality of cooling fins and at least a guide heat pipe. The cooling fins stack to one another with at least a through hole at the respective cooling fin for being penetrated with the guide heat pipe. A projecting annular part is disposed at a side of the respective cooling fin to surround the circumference of the through hole with an indented spot at the periphery of the projecting annular part. The outer side of said guide heat pipe has an elongated recess extending along the length thereof to correspond to the indented spot such that the indented spot is capable of fitting with the recess after the guide heat pipe passing through the through hole respectively to facilitate the subsequent welding job.

1 . A heat dissipation module comprising:
 a plurality of cooling fins stacking to one another with at least a through hole at the respective cooling fin to align to each other; and   at least a guide heat pipe penetrating said through hole;   wherein, a projecting annular part is disposed at a side of the respective cooling fin to surround the circumference of said through hole with an indented spot at the periphery of said projecting annular part; and the outer side of said guide heat pipe has an elongated recess extending along the length of said guide heat pipe to correspond to said indented spot such that said indented spot is capable of fitting with said recess after said guide heat pipe passing through said through hole respectively.   
   
   
       2 . The heat dissipation module as defined in  claim 1 , wherein said recess has a shape to accommodate said indented spot. 
   
   
       3 . The heat dissipation module as defined in  claim 1 , wherein said recess extends continuously or discretely.
