Heat radiating structure formed from quickly connectable U-sectioned fins

Abstract

A heat radiating structure is formed from at least two sequentially connected U-sectioned fins, each of which includes a middle portion and two vertically bent sidewall portions. The middle portion is provided along two longitudinal edges with insertion holes, and the sidewall portions are correspondingly provided along outer edges with forward projected locking means. A distance by which the locking means projects from the sidewall portion is small or equal to a distance between the insertion hole and the locking means. The U-sectioned fins oriented in the same direction can be quickly connected one by one to form the heat radiating structure by inserting the locking means on a preceding U-sectioned fin into the insertion holes on a following U-sectioned fin. The connected U-sectioned fins are attached to a working heat source by means of a thermal conductive material to quickly locate the heat radiating structure in place.

What is claimed is:  
     
         1 . A heat radiating structure, comprising at least two U-sectioned fins, each said U-sectioned fin including a flat middle portion and two sidewall portions bent along and extended from two longitudinal edges of said middle portion at a right angle; said middle portion being provided near and along the two longitudinal edges with a plurality of insertion holes, and said two sidewall portions being formed of a plurality of forward projected locking means at positions corresponding to said insertion holes; a distance by which a front end of said locking means projecting from an outer edge of said sidewall portion being small or equal to a distance between said insertion hole and a rear end of said locking means; the front end of said locking means being formed into two symmetrical barbs spaced from each other to define a notch therebetween; said notch enabling said two barbs to be elastically compressed toward each other; whereby said at least two U-sectioned fins, when being oriented in the same direction, can be quickly connected to one another to form said heat radiating structure by inserting said locking means on a preceding U-sectioned fin into said insertion holes on a following U-sectioned fin.  
     
     
         2 . The heat radiating structure as claimed in  claim 1 , wherein said barbs formed at the front end of said locking means are in the shape of an arrow.  
     
     
         3 . The heat radiating structure as claimed in  claim 1 , wherein said U-sectioned fins are made of a copper material.  
     
     
         4 . The heat radiating structure as claimed in  claim 1 , wherein said U-sectioned fins are made of a red copper material.
