Heat sink radiation fin and base block mounting structure

Abstract

A heat sink radiation fin and base block mounting structure includes a base block providing a plurality of grooves at one side thereof, and a plurality of radiation fins each having a bottom edge thereof stamped to provide a plurality of folded portions and hook portions, the folded portions and hook portions of the radiation fins being inserted into the grooves of the base block and then embedded in or clamped to the base block.

What is claimed is: 
     
         1 . A heat sink radiation fin and base block mounting structure, comprising a base block having a plurality of grooves at one side thereof, and a plurality of radiation fins respectively mounted in said grooves of said base block, wherein each said radiation fin has a bottom edge thereof stamped to provide a plurality of folded portions, and the folded portions of said radiation fins are inserted into said grooves of said base block and then integrally embedded in or clamped to said base block. 
     
     
         2 . The heat sink radiation fin and base block mounting structure as claimed in  claim 1 , wherein the folded portions of each said radiation fin are equally spaced along the bottom edge of the respective radiation fin and alternatively projecting in two opposite directions. 
     
     
         3 . The heat sink radiation fin and base block mounting structure as claimed in  claim 2 , wherein the folded portions of each said radiation fin have an L-shaped profile. 
     
     
         4 . The heat sink radiation fin and base block mounting structure as claimed in  claim 3 , wherein the folded portions of each said radiation fin are disposed at a same elevation. 
     
     
         5 . The heat sink radiation fin and base block mounting structure as claimed in  claim 1 , wherein each said radiation fin further comprises a plurality of hook portions respectively disposed between each two adjacent folded portions of the respective radiation fin. 
     
     
         6 . The heat sink radiation fin and base block mounting structure as claimed in  claim 5 , wherein said hook portions are shaped like a barb. 
     
     
         7 . The heat sink radiation fin and base block mounting structure as claimed in  claim 5 , wherein each said radiation fin further comprises a plurality of openings; each said hook portion extends obliquely upwardly from one said opening. 
     
     
         8 . The heat sink radiation fin and base block mounting structure as claimed in  claim 1 , wherein the folded portions of said radiation fins are integrally embedded in said grooves of said base block by casting liquid aluminum into said grooves. 
     
     
         9 . The heat sink radiation fin and base block mounting structure as claimed in  claim 1 , wherein the folded portions of said radiation fins are inserted into said grooves of said base block and clamped to said base block by means of deforming two opposite sidewalls of each said groove of said base block. 
     
     
         10 . The heat sink radiation fin and base block mounting structure as claimed in  claim 1 , wherein said base block has at least one heat pipe press-fitted therein.
