Cooling fin assembly

Abstract

A cooling fin assembly includes a plurality of fins, each having a latching element on the top edge and the bottom edge, to couple with each other in series, forming an annular arrangement. The fins coupled in the annular fashion are surrounded and confined by a strapping ring. The fins have respectively a bottom plate extended vertically from the fins to be in contact with the top surface of a base, which has a bottom surface in contact with the surface of a heat source, to dissipate heat.

1 . A cooling fin assembly, comprising: 
 a plurality of fins coupled in series and formed in an annular fashion, each of the fins having an outer edge, an inner edge, a top edge and a bottom edge, the top edge and the bottom edge having respectively a latching element extended towards one side in the middle, the latching element having a latching section on the end of the fin and a latching opening on a juncture the latching element and the fin to receive the latching section of another fin to form a coupling condition;    a bottom plate extended vertically from the bottom edge thereof; and    a strapping ring surrounding the periphery of the fins.    
   
   
       2 . The cooling fin assembly of  claim 1 , wherein the latching section has a protrusion on two edges extending outwards, the two protrusions having respectively a pointed end spaced from each other at a distance greater than the width of the latching opening.  
   
   
       3 . The cooling fin assembly of  claim 1 , wherein the bottom plate is formed substantially in a fan shape and is coupled with one another in a juxtaposed manner to form an annular plane.  
   
   
       4 . The cooling fin assembly of  claim 1 , wherein the bottom plate is formed substantially in a fan shape and is coupled with one another in a juxtaposed manner to form a circular plane.  
   
   
       5 . The cooling fin assembly of  claim 1 , wherein the strapping ring is a band which has two ends coupling with each other.  
   
   
       6 . The cooling fin assembly of  claim 5 , wherein the band has two ends formed respectively a connecting hook and a connecting hole.  
   
   
       7 . The cooling fin assembly of  claim 1 , wherein the outer edge has a notch to couple with the strapping ring.  
   
   
       8 . The cooling fin assembly of  claim 1  further having a base which has a top surface in contact with the bottom plate of the fins and a bottom surface in contact with a heat source.  
   
   
       9 . The cooling fin assembly of  claim 8 , wherein the top surface is conical, the bottom plate of the fins being formed substantially in a fan shape to form an angle with the latching element such that the bottom plate is coupled with each other in a juxtaposed manner to form a conical surface.  
   
   
       10 . The cooling fin assembly of  claim 8 , wherein the base is a two-stage structure which forms a circular plate abutting the top surface and a rectangular plate abutting the bottom surface.  
   
   
       11 . The cooling fin assembly of  claim 10  further including a mounting frame to latch on a mounting dock, the mounting frame having a holding bore mating the bottom surface of the base.  
   
   
       12 . The cooling fin assembly of  claim 11 , wherein the mounting frame has elastic reeds extended outwards and upwards in an inclined manner from side edges to form an angle with the mounting frame, each of the elastic reeds having a front end latching on the mounting dock.  
   
   
       13 . The cooling fin assembly of  claim 12 , wherein the mounting dock has a bottom and a plurality of side plates, the bottom having an open area in the center, each of the side plates having at least one hooking hole to couple with the front end of the elastic reed.  
   
   
       14 . The cooling fin assembly of  claim 12 , wherein the elastic reeds includes a plurality of first elastic reeds and a plurality of second elastic reeds, each of the first elastic reeds having a first hook section on a front end thereof that has a opening directing upwards, each of the second elastic reeds having a second hook section on a front end thereof that has a opening directing upwards and a bucking section.  
   
   
       15 . The cooling fin assembly of  claim 12 , wherein the elastic reeds includes a plurality of first elastic reeds and a plurality of second elastic reeds, each of the first elastic reeds having a first hook section on a front end thereof that has a first opening directing upwards, each of the second elastic reeds having a second hook section on a front end thereof formed in a L-shaped cross section that has a opening directing upwards and a bucking section.  
   
   
       16 . The cooling fin assembly of  claim 1  further having a fan mounted on the fins.  
   
   
       17 . The cooling fin assembly of  claim 16  further having a plurality of anchoring elements which have one end coupling with the fan and other end latching on the outer edge of the fins.  
   
   
       18 . The cooling fin assembly of  claim 17 , wherein each of the anchoring elements has a inserting pillar, the fan having a plurality of inserting holes corresponding to the inserting pillar.  
   
   
       19 . The cooling fin assembly of  claim 18 , wherein the fan has a plurality of lugs on the periphery and the inserting holes are located on the lugs.  
   
   
       20 . The cooling fin assembly of  claim 17 , wherein each of the anchoring elements has a flange on one end, each of the fins having an indented portion on the outer edge to couple with the flange.
