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.

Abstract: A heat-dissipating element with connecting structures comprises at least two opposite stop edges. Each stop edge is formed with at least one connecting structure, and each connecting structure includes a first connecting portion which has a fastener and a fastening hole and a second connecting portion which has a positioning concave portion and a positioning protrusion. The heat-dissipating elements are assuredly assembled with each other through the engagement and fastening connection of the first connecting portion and the second connecting portion.
