A heat sink for removing heat from a heat-generating device includes a fin combination (10). The fin combination includes a plurality of fins interconnected together, each fin including a body (12), a flange (14) extending from the body and bent from an edge of the body, a tab (16) extending from an outer edge of the flange, a slot (17) formed in the body, and a detent (160) formed at a junction portion between the tab and the flange. The slot of a fin receives the tab of an adjacent fin. The detent of the adjacent fin engages with the flange and the body of the fin at a position near the slot of the fin, whereby the fin combination has the fins firmly connected together.

What is claimed is: 1. A heat sink comprising: a fin combination comprising a plurality of fins interconnected together, each fin comprising: a body; a flange bent from an edge of the body, the flange having an outer edge opposing to the body; a tab extending from the outer edge of the flange; a detent formed at a junction portion between the tab and the flange; and a slot formed in a junction between the body and the flange; wherein the tab of a fin extends through the slot of an adjacent fin with the detent of the fin abuts the body of the adjacent fin, the flange of the adjacent fin contacts the detent of the fin, the tab of the fin contacts an inner side of the flange of the adjacent fin and the flange of the adjacent fin is pressed to the tab of the fin to connect therewith. 2. The heat sink as described in claim 1, wherein the body further comprises a hole defined therein. 3. A method for assembling a heat sink, comprising steps of: a). preparing a plurality of fins each comprising a body with a flange extending perpendicularly from the body, a tab extending from the flange, and a slot formed between the body and the flange, the flange forming a protrusion on an outer side thereof; b). inserting the tab of a fin into a slot of an adjacent fin to a position where the tab is located neighboring the protrusion of the flange of the adjacent fin; and c). pressing the protrusion of the flange of the adjacent fin to flatten the protrusion to thereby securely fasten the flange of the adjacent fin and the tab of the fin together, wherein a detent is formed at a junction between the tab and the flange of the fin. 4. The method for assembling a heat sink as described in claim 3, wherein the flange of the adjacent fin further comprises a recess in an inner side thereof corresponding to the protrusion, and at the step b), the tab of the fin is inserted into the slot and received in the recess. 5. The method for assembling a heat sink as described in claim 4, wherein the recess has a shape corresponding to that of the tab. 6. The method for assembling a heat sink as described in claim 4, wherein the body defines a hole therein. 7. The method for assembling a heat sink as described in claim 4, further comprising a step d) following the step c): d). mounting the fin combination on a metal base.
