Fin type heat sink fixing assembly

Abstract

A fin type heat sink includes a heat conducting base, fins, pressing plates and positioning members. The fins are parallely installed with an interval apart from each other on the heat conducting base, and a fixing plate is perpendicularly extended from the bottom of each fin. The fixing plate includes through holes, and the pressing plate is installed corresponding to the fin. Each pressing plate is installed on the fixing plate and has combining holes corresponding to the through holes, and the positioning member is fixed onto the heat conducting base, and the positioning member is passed through the through hole and the combining hole and fixed onto the pressing plate, such that the pressing plate presses the fixing plate flatly onto the heat conducting base. Therefore, heat at the heat conducting base can be conducted to the fins quickly to enhance the thermal conduction effect.

1 . A fin type heat sink fixing assembly, comprising:
 a heat conducting base;   a plurality of fins, installed in parallel with an interval apart from each other on the heat conducting base, and each fin having a fixing plate perpendicularly extended from the bottom of the fin, and the fixing plate having a plurality of through holes formed thereon;   a plurality of pressing plates, installed at position corresponding to the fins, and each pressing plate being installed on the fixing plate, and having a plurality of combining holes corresponding to the through holes respectively; and   a plurality of positioning members, fixed onto the heat conducting base, and each positioning member passing through the through hole and the combining hole and being fixed onto the pressing plate, such that the pressing plate presses against the fixing plate to attach the fixing plate flatly onto the heat conducting base.   
     
     
         2 . The fin type heat sink fixing assembly of  claim 1 , wherein the fin includes a positioning plate separately and perpendicularly extended from both sides of the fin, and the positioning plates adjacent to the fin are abutted with each other. 
     
     
         3 . The fin type heat sink fixing assembly of  claim 1 , wherein the pressing plate has an appearance corresponding to the size and shape of the fixing plate. 
     
     
         4 . The fin type heat sink fixing assembly of  claim 1 , wherein the positioning members are protruding pillars disposed at positions corresponding to the through holes respectively to be arranged on the heat conducting base. 
     
     
         5 . The fin type heat sink fixing assembly of  claim 4 , wherein the positioning members and the heat conducting base are integrally formed. 
     
     
         6 . The fin type heat sink fixing assembly of  claim 4 , wherein the positioning members and the heat conducting base are installed separately, and the heat conducting base includes a plurality of slots formed thereon and provided for fixing the positioning members respectively. 
     
     
         7 . The fin type heat sink fixing assembly of  claim 6 , wherein the positioning member is pressed to form a pressing block greater than the diameter of the combining hole on the pressing plate. 
     
     
         8 . The fin type heat sink fixing assembly of  claim 7 , wherein the pressing block is substantially in a flat circular shape. 
     
     
         9 . The fin type heat sink fixing assembly of  claim 1 , wherein the positioning member is a bolt, and the combining hole is a corresponding screw hole. 
     
     
         10 . The fin type heat sink fixing assembly of  claim 9 , wherein the heat conducting base includes a plurality of fixing holes formed thereon, and the bolt is passed through the fixing hole and the through hole and secured into the screw hole. 
     
     
         11 . The fin type heat sink fixing assembly of  claim 1 , wherein the positioning member is a bolt, and the heat conducting base includes a plurality of fixing holes formed thereon, and each fixing hole is a screw hole, and the bolt is passed through the combining hole and the through hole and secured into the screw hole.
