Structure of heat dissipating fins

Abstract

A structure of heat dissipating fins that can be assembled with increased efficiency without the use of adhesive agents such as soldering tin, and so on, while ensuring a tight fit on cooling ducts. More than one through hole defined in each of the heat dissipating fins that provide for cooling ducts to insert therein. A staircase-like member extends backward from each of the through holes to form a catch groove, and a catch end further extends backward from each of the catch grooves. When the heat dissipating fins are being successively disposed onto the cooling ducts through the through holes, the catch ends are respectively disposed into the catch grooves of the heat dissipating fin positioned therebehind, thereby producing a tight clamping effect on the cooling ducts, further causing an immobile mutual fastening between the heat dissipating fins without the use of soldering tin.

1 . A structure of heat dissipating fins comprising more than one through hole defined in each heat dissipating fin that provide for cooling ducts to insert therein, and characterized in that a staircase-like member extends backward from each of the through holes to form a catch groove, and a protrudent catch end further extends backward from each of the catch grooves, moreover, outer diameter of the catch ends is slightly larger than inner diameter of the catch grooves.  
   
   
       2 . The structure of heat dissipating fins as described in  claim 1 , wherein the outer diameter of the catch end assumes a backward extending gradual tapering funnel form.  
   
   
       3 . The structure of heat dissipating fins as described in  claim 1 , wherein a vent groove is defined in an end of the catch end.  
   
   
       4 . The structure of heat dissipating fins as described in  claim 1 , wherein the catch ends of the heat dissipating fin positioned in front are respectively disposed into the catch grooves of the heat dissipating fin positioned therebehind, and tightened to clamp onto the cooling ducts.
