Demand of a small fan has been increasing with the flow of miniaturization of electronic devices. Piezoelectric fan is one of the fan that has been proposed. A piezoelectric fan is a flexible cantilever beam whose vibration is actuated by means of a piezoelectric material. Such fans have been employed for the enhancement of heat transfer by increasing the fluid circulation in regions. However disadvantage of this fan is low pressurization. This paper provides a thin profile fan that using the generation principle of travelling space between two reasonantly-driven plates. This theory has been achieved with both ends fixed string. This equipment is a simple mechanism that consists of only two plates, and it has an advantage of thin to the direction of ventilation. And it has advantage of low cost, because the mechanism is simple. The primary focus of this paper is to verify the air flow of our proposed fan.
