Abstract
The present invention relates to a cooling system specially used generated when a CPU of a desktop computer operates. The present invention provides a magnetic-levitated cooling circulatory mechanism, which comprises an outer ring heat spreader having a hollow position therein, a plurality of heat-radiating fins inside the outer ring heat spreader, a magnetic hollow cavity capable of slidably rotating in the hollow position of the outer ring heat spreader, and a magnetic windmill placed at one end of the outer ring heat spreader. The magnetic windmill is driven to rotate by a power source. When the magnetic windmill rotates, the magnetic hollow cavity can be attracted to rotate so as to quickly transfer heat source, thereby achieving the heat-radiating function of compulsory flow of fluid.
