Connecting Structure for Connecting Heat Radiation Fins

Abstract

A connecting structure for connecting heat-radiation fins comprises a plurality of heat-radiation fins each having a heat conductive portion with both edges folded into wing portions. The wing portions of the respective heat-radiation fins are different in width, and the heat-radiation fins are classified into narrow and wide heat-radiation fins, between each narrow heat-radiation fin and wide heat-radiation fin is connected a connecting fin, each wing portion of the respective heat-radiation fins and the connecting fins is defined with receiving apertures, an outer portion of the respective receiving apertures extends outward to form a connecting portion to be received in a corresponding receiving aperture of a neighboring fin. The connecting fins are provided with receiving apertures and connecting portions which are sized corresponding to that of neighboring narrow and wide heat-radiation fins.

1 . A connecting structure for connecting heat-radiation fins, comprising:
 a plurality of heat-radiation fins each having a heat conductive portion with both edges folded into wing portions, the wing portions of the respective heat-radiation fins being different in width, and the heat-radiation fins being classified into narrow and wide heat-radiation fins, between each narrow heat-radiation fin and wide heat-radiation fin being connected a connecting fin, each wing portion of the respective heat-radiation fins and the connecting fins being defined with receiving apertures, an outer portion of the respective receiving apertures extending outward to form a connecting portion to be received in a corresponding receiving aperture of a neighboring fin;   the connecting fins being provided with receiving apertures and connecting portions for engaging with that of neighboring narrow and wide heat-radiation fins.   
   
   
       2 . The connecting structure for connecting heat-radiation fins as claimed in  claim 1 , wherein a width of the respective wing portions of the narrow heat-radiation fins is narrower than that of the wide heat-radiation fins, each wing portion of the narrow heat-radiation fins includes connecting portions and receiving apertures which are sized to meet the width of the wing portion of the narrow heat-radiation fin, the wing portions of the wide heat-radiation fins are wider than the wing portions of the narrow heat-radiation fins, the connecting portions and the receiving apertures of the wing portions of the wide heat-radiation fins are longer than that of the narrow heat-radiation fins. 
   
   
       3 . The connecting structure for connecting heat-radiation fins as claimed in  claim 2 , wherein the connecting fins are classified into two types: one type of connecting fin is connected from the wide heat-radiation fin toward to the narrow heat-radiation fin, and the other type of connecting fin is connected from the narrow heat-radiation fin toward the wide heat-radiation fin. 
   
   
       4 . The connecting structure for connecting heat-radiation fins as claimed in  claim 3 , wherein wing portions of the connecting fins are equal in width to the wing portions of the wide heat-radiation fins, and the receiving apertures in the wing portions of the connecting fins are equal in size to the connecting portions of the wide heat-radiation fins, the connecting portions projecting from the wing portions of the connecting fins toward the receiving apertures of the narrow heat-radiation fins are the same in size and shape as the receiving apertures of the narrow heat-radiation wing portions. 
   
   
       5 . The connecting structure for connecting heat-radiation fins as claimed in  claim 3 , wherein wing portions of the connecting fins have the same width as the wing portions of the narrow heat-radiation fins, the receiving apertures of the wing portions of the connecting fins have the same size as the connecting portions of the narrow heat-radiation fins, and the connecting portions of the wing portions of the connecting fins are also the same in shape and size as the receiving apertures of the wide heat-radiation fins.
