Effects of obstruction in front of a piezoelectric micro blower on performance characteristics

This study describes a performance characteristic of a piezoelectric micro blower which may be available for a novel cooling technology 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 effect of the obstruction, which simulates the electrical components and is mounted very near the blower, on the P-Q characteristic was investigated. Especially we tried to measure the performance characteristic of the micro blower when the obstruction was mounted in front of the blower. 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 in front of the blower. There is a possibility that this novel blower can achieve a high cooling performance regardless of a packaging density of electronic components in electronic equipment.
