Abstract

A flapping fan for cooling electronic devices includes an elongated piezo actuator, two supporting members, two connecting members, and a thin blade. The supporting members are attached to the piezo actuator at its two ends, while the blade is connected to the piezo actuator through the connecting members. When activated by an AC signal, the piezo actuator oscillates around its neutral position, which causes the blade to oscillate. The blade rotates around its leading edge when its direction of motion changes, keeping its angle of incidence lower than ninety degrees. This helps the flapping fan to generate a significant air flow.
