Patent ID: 8520384

Claim:
A heat dissipating device comprising: a heat dissipater thermally coupled to a heat generator, the heat dissipater being configured to transmit heat from the generator to air; a blade that forms an air flow to at least a portion of the heat dissipater; a blade drive that drives the blade to alternatingly rotate within a preset range of angles by an electromagnetic force; wherein the blade drive includes a shaft, a bobbin connected to the shaft so as to be rotatable about a rotation axis of the shaft, the bobbin having the blade mounted to one side thereof, and an electromagnetic force generator having a coil configured to pass a current therethrough and at least one magnet spaced from the coil; and wherein the heat dissipater has one surface in contact with the heat generator and an other surface with a plurality of heat dissipating fins provided on an edge thereof spaced from one another.
