Abstract

A heat sink includes a base, a heat sink base, a bearing, a rotor, and a stator. The base includes a heat conduction plate and a support pillar disposed on the heat conduction plate. The heat sink base includes a support plate and heat sink fins disposed on the support plate. The support plate is correspondingly disposed over the heat conduction plate, and a gap is formed between the support plate and the heat conduction plate. A bearing is disposed between the support pillar and the heat sink base. A rotor is disposed on the heat sink base, the stator is disposed corresponding to the rotor and fixed on the base. The heat sink base rotates with respect to the support pillar by an electromagnetic effect between the rotor and the stator.
