Abstract
This study describes a performance characteristic of a piezoelectric micro blower which may be available for a cooling device of portable electronic equipment. We especially focus on the investigation whether the micro blower is available for a cooling method of high-density packaging electronic equipment or not. In this paper, the effects of the obstruction, which simulates the electrical components and is mounted very near the blower, on the performance characteristic is investigated. From the experiment, it is found that the performance characteristic of the proposed micro blower is almost not changed regardless of the existence of the obstruction.
