Abstract:
A heat-dissipating module for removing heat generated from a heat-generating device, comprising:a lower housing made of a highly thermal conductive material; an upper housing having an opening in the center thereof, wherein when said upper housing and said lower housing are jointed together, an outlet is defined; a blade portion; a first magnet portion including a plurality of first magnets; a second magnet portion having a plurality of second magnets, a support, a shaft and at least one rib, wherein a permanent magnetic field is formed between said plurality of first magnets and said plurality of second magnets, a free end of said shaft being inserted into a sleeve of said lower housing, and said at least one rib being interconnected with the other end of said shaft and said support; and a circuit board between said first magnet portion and said second magnet portion and having a plurality of winding coils, wherein when a current is applied to said plurality of winding coils, said permanent magnetic field is repulsed to rotate said blade portion, and an ambient air flow is inhaled from said opening and exhaled via said outlet.
