A rotary heat sink comprising a heat sink body receiving heat from a heating body, a heat dissipating part fixed rotatably to the heat sink body, and a driving means for rotating the heat dissipating part relatively to the heat sink body. Heat of the heat sink body is transmitted directly to the rotating heat dissipating part and dissipated therefrom. The rotary heat sink can suppress noise significantly and has a relatively small capacity. |
