Abstract

Several types of piezoelectric fans for cooling electronic devices were constructed and tested at 60 Hz, 110 V and 220 V, respectively. The aim of the work is to investigate the possibility of replacing the rotary type of fan in some noise-sensitive electronic devices. Different vibrating metal plates were tested and analyzed theoretically. It is found that the resonant frequency of the vibrating plate decreases with the increase of its length (l) if the length of the piezoelectric ceramic bimorph (L) is kept construct. The series-type fan with l = 31.8 mm, made of phosphor bronze vibrating plate (S6), shows the highest value of fan tip displacement of 35.5 mm and produced wind velocity of 3.1 m/s driven by a 220 V, 60 Hz power source.
