Abstract
Abstract A heat dissipation device including a base portion having a plurality of projections extending radially therefrom. A cooling fluid and circulation tubes are used to increase the efficiency of the heat dissipation device by pumping the heat (via the cooling fluid) from the hot base portion to the tips of the projections. The cooling fluid is circulated by a small centrifugal pump, which is driven by a fan attached to the heat dissipation device used for creating forced air-cooling.
