Abstract

A heat sink includes at least one first fin and at least one second fin. In the present invention, the first fin has at least one oblique vent. A side of the oblique vent has a baffle, the first and second fin are disposed parallelly, and the second fin is located on the side of the baffle of the first fin. The second fin has at least one oblique vent. The heat sink can guide airflow into a central area thereof to prevent the hub of a fan from blocking airflow at the central area, so that the dissipation efficiency is improved.
