Investigation of Radial Piezoelectric-Magnetic Fan for Electronic Cooling System

Application of piezoelectric fan in cooling electronic devices has been proven that it is more efficient that natural convection and has high potential to replace existing rotary fan. Radial Piezoelectric-Magnetic fan (RPMF) has introduced the integration of piezo-magnet to reduce power consumption and radial orientation to increase the repulsive magnetic force to be distributed to other adjacent magnetic fans. In this study 4 magnetic fans were activated by a single piezoelectric fan. All fans were vibrating but in reducing amplitude as the passive fans are located farther from the driving fan (piezo fan). The distribution of repulsive magnetic fan is different in array and radial orientation. The radial orientation has a better distribution angle compared to array orientation.
