Heat sink and heat-dissipating fins of the same

Abstract

A heat sink and heat-dissipating fins have wave-shaped folds. The heat sink includes a plurality of heat-dissipating fins that are radially connected together to form a ring. The inside of the heat-dissipating fins is formed with an accommodating space for allowing a heat-generating element to be disposed therein. The heat-dissipating fin is a metallic piece with its one side bent vertically to form a fold. The fold is bent continuously to form a wave shape. Via the wave-shaped folds, the user can grip the heat-dissipating fins easily. Further, the rigidness and strength of the fold can be increased.

1 . A heat-dissipating fin, the heat-dissipating fin being a metallic piece with one side thereof bent vertically to form a fold, and the fold being bent continuously to form a wave shape. 
     
     
         2 . The heat-dissipating fin according to  claim 1 , wherein the other side of the metallic piece is provided with a locking portion, the locking portion is connected with another heat-dissipating fin. 
     
     
         3 . The heat-dissipating fin according to  claim 2 , wherein the locking portion is a protruding plate, an interior of the protruding plate is provided with an insertion hole. 
     
     
         4 . The heat-dissipating fin according to  claim 3 , wherein the protruding plate is formed with a ridge. 
     
     
         5 . The heat-dissipating fin according to  claim 1 , wherein the other side of the metallic piece extends vertically to form a retaining piece. 
     
     
         6 . A heat sink adhered to outside of a heat-generating element, the heat sink comprising a plurality of heat-dissipating fins, the heat-dissipating fins being connected radially to form a ring, an interior of the heat-dissipating fins being formed with an accommodating space for the heat-generating element to be disposed therein, the heat-dissipating fin being a metallic piece with one side thereof bent vertically to form a fold, and the fold being bent continuously to form a wave shape. 
     
     
         7 . The heat sink according to  claim 6 , wherein the other side of the metallic piece is provided with a locking portion, the locking portion is connected with another heat-dissipating fin. 
     
     
         8 . The heat sink according to  claim 7 , wherein the locking portion is a protruding plate, the interior of the protruding plate is provided with an insertion hole. 
     
     
         9 . The heat sink according to  claim 8 , wherein the protruding plate is formed with a ridge. 
     
     
         10 . The heat sink according to  claim 6 , wherein the other side of the metallic piece extends vertically to form a retaining piece, the retaining piece is adhered to the heat-generating element. 
     
     
         11 . The heat sink according to  claim 6 , wherein a heat-dissipating path is formed between any two heat-dissipating fins. 
     
     
         12 . A heat sink adhered to a heat-generating element, the heat sink comprising a plurality of heat-dissipating fins, the heat-dissipating fins being stacked up in parallel to one another, the heat-dissipating fin being a metallic piece with one side bent thereof vertically to form a fold, and the fold being bent continuously to form a wave shape. 
     
     
         13 . The heat sink according to  claim 12 , wherein the metallic piece is formed into a rectangular shape. 
     
     
         14 . The heat sink according to  claim 13 , wherein two opposite sides of the metallic piece are bent vertically to form a fold respectively, the two folds are bent continuously to form a wave shape. 
     
     
         15 . The heat sink according to  claim 12 , wherein a heat-dissipating path is formed between any two heat-dissipating fins.
