Abstract: A heat dissipation module including a supporting frame, a driver, a linkage, a first magnet and a plurality of magnetic blades is provided. The supporting frame has a chute. Moreover, one end of the linkage has a protrusion passing through the chute. The other end of the linkage is connected to the driver. The first magnet is disposed on the protrusion. In addition, the repelling magnetic blades are pivoted on the supporting frame. The outermost magnetic blade faces the first magnet and they repel each other.

Abstract: A swing type fan including a frame, a motor, at least one blade, at least one first magnetic element and at least one second magnetic element is provided. The motor is fixed to the frame and has a shaft passing through the frame. The blade is disposed between the shaft and the frame and has a first side and a second side opposite to the first side. The first side of the blade is connected to the frame. The first magnetic element is disposed on the blade and is located between the first side and the second side of the blade. The second magnetic element is connected to the shaft and is corresponding to the first magnetic element. The second side of the blade swings via a magnetic force between the first magnetic element and the second magnetic element as the shaft drives the second magnetic element to rotate.

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.
