Abstract
This study conducts a measurement of a performance of a piezoelectric micro blower. Mobile electronic equipment becomes smaller and thinner while their functions become more complex. As a result, a lot of components are mounted in an enclosure and flow passages for the cooling air become narrow. This causes significant pressure drop and general cooling fans cannot supply enough cooling air. We focused on a novel piezoelectric micro blower. In order to predict accurate cooling performance of the piezoelectric micro blower in thermal design, we tried to develop the measurement system of the performance characteristic curve of the blower. By using our system, we succeeded to measure the relationship between the supply flow rate and the static pressure rise of the micro blower.
