Abstract :
A vibrating fan system is being pursued as a means to create a heat dissipation system. To improve the efficiency of a heat dissipation system, a novel multiple vibrating-fan system that is actuated by both piezoelectric effect and magnetic force has been developed. The performance of the system is affected by the geometry of the fans and the distance between the fans and the heat sink. The surface temperature of a 20W heat sink can be reduced from 67°C to 50°C using this multiple vibrating-fan cooling system; The power consumption of this system is only 0.027 W, which is lower than a single piezoelectric (PZT) fan. Thus, the novel design of a cooling system with multiple fans shows effective thermal dissipation as well as low power consumption.
