Abstract:
1. A cooling apparatus, comprising: a base member; a first end of a flat piezoelectric actuator configured to be connected to the base member; at least one expansion mechanism configured to be connected to a second end of the piezoelectric actuator and pivot by the swinging of the piezoelectric actuator; a blade member configured to be connected to the expansion mechanism and swing by the pivoting of the expansion mechanism; and a blade lever configured to connect the expansion mechanism with the blade member, wherein 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, the flat piezoelectric actuator, the expansion mechanism, the blade member, and the blade lever are disposed in a same first plane, the expansion mechanism is supported so as to be rotatable relative to the base member around a first axis, the first axis being perpendicular to the first plane, and the blade lever is supported so as to be rotatable relative to the base member around a second axis, the second axis being perpendicular to the first plane.
