Abstract
A heat dissipation device, electrically connected to an intermittent power source, is used for dissipating heat generated by a heat-generating element on a circuit board. The heat dissipation device has at least one coil and at least one vibrating sheet. The coil is used to receive the intermittent power source to produce a magnetic field. One end of the vibrating sheet is fixed, and the other end is suspended over the coil. The suspended end flutters periodically under the magnetic force of the intermittent magnetic field, so as to produce an airflow.
