Abstract

The utility model relates to a heat fin structure which is provided with an upper edge fold and a lower edge fold on a heat fin, and is also provided with projecting horizontal gripping pieces on four corners of the edge folds or on an upstanding plated surface of the heat fin. On each horizontal gripping piece body is arranged a slot which has a corresponding shape and location for the horizontal gripping piece to insert in and is provided with a gripping ear on the back end to fix the horizontal gripping piece. Two adjacent horizontal gripping pieces of a back heat fin are inserted into the slots of a front heat fin for combination and gripping ears are used for gripping the bottom gripping faces of the horizontal gripping pieces to prevent the horizontal gripping pieces from slipping and combine the two heat fins into a heat fin group. The utility model which has the advantages of easy molding, rapid assembly and quick heat emission can protect and prolong service life of a computer CPU.
