Heat sink

摘要

A heat sink includes a number of primary fin plates and a number of secondary spacing plates alternately arranged and fixed together by fasteners extending therethrough. Bottom edges of the plates are flush with each other to form a surface positionable on a heat generating component. Top edges of the primary plates are located above top edges of the secondary plates. Upper portions of the primary plates are formed between the top edges thereof and the top edges of the secondary plates. A number of openings are defined in the upper portion of each primary plate to increase the surface area thereof. The openings may be grooves or slots. Positioning bosses are formed on a first face of each plate for reception in recesses defined in a second face of an adjacent plate thereby properly positioning the plates with respect to each other.
