HEAT SINK

摘要

A heat sink includes a base and a number of fins mounted parallelly on the base. Each fin defines a number of vents, and two heat dissipating pieces protrude from opposite sides of each vent. The heat dissipating pieces of each vent cooperatively bounds an opening communicating with the corresponding vent. The number of openings of each fin is aligned with the number of openings of the other fins. The aligned openings of the number of fins cooperatively define a number of first air channels perpendicular to the number of fins. The number of heat dissipating pieces bound a number of second air channels parallel to the number of fins.
