Heat radiating structure formed from quickly connectable U-sectioned fins

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.
