Heat sink assembly

摘要

A heat dissipation assembly includes a base with a ridge and multiple fins mounted on top of the base. Each of the fins has a plate with a cutout defined in a mediate portion of a bottom edge to correspond to the ridge of the base, two first bends respectively extending from opposite sides of the cutout in a same direction from the bottom edge and a second bend formed on a top edge of the cutout. The fins are able to be securely mounted on top of the base via the two first bends.
