ABSTRACT
Piezoelectric fan is a new concept of miniature devices, compared to traditional fans, there are three advantages: small volume, less power consumption and noise-reduction; in other words, these advantages are quite applicable in these electronic products. This article focuses on the design and fabrication different types of piezoelectric fans, the driving voltage, driving frequency of the
piezoelectric fan's wind velocity and tip displacement, to find out the maximum wind speed and the best cooling design. Piezoelectric fan consists of three basic components: the piezoelectric patch, blade and Metal Substrate, and between the three structures by the appropriate adhesive bonding. Focus on using experimental measurement set up anemometer and heated to test different modules fans caused by wind velocity and cooling capacity. The results showed the critical impact of wind velocity is frequency; cooling capacity increases with wind velocity.
