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.

Abstract: The present invention relates to a pump heat spreader and more particularly, to a cooling system specially used generated when a CPU of a desktop computer operates. The present invention includes an outer ring heat spreader, a plurality of heat-radiating fins inside the outer ring heat spreader, a pump, and a fan. Different from the conventional open-end heat-spreading fins, the present invention provides a closed and concentrated heat-radiating structure to achieve the heat-radiating function of compulsory flow of fluid. Through the special structure of the present invention, heat can be effectively and totally radiated out of the computer in circulatory way and with increased heat-radiating area.
