Abstract

A cooling apparatus includes a base member, a flat piezoelectric actuator, at least one expansion mechanism, and a blade member. The flat piezoelectric actuator is configured to be connected at one end to the base member. At least one expansion mechanism is configured to be connected to the other end of the piezoelectric actuator and pivot by the swinging of the piezoelectric actuator. The blade member is configured to be connected to the expansion mechanism and swing by the pivoting of the expansion mechanism. The blade member performs a fanning action by the swinging of the piezoelectric actuator and the pivoting of the expansion mechanism if AC power is applied to the piezoelectric actuator.
