Internet of Things: A Monitoring and Control System for Rockmelon Farming 7 (2018): Special Issue 2018: Future Technology Towards a Smart and Healthy Society International Journal of Integrated Engineering: Vol. RPMF generates average wind velocity of 0.4m/s compared to array orientation 0.17m/s.įeasibility Study of a Low Cost Saltwater Lamp for Rural Area 30% of power consumption per unit coverage area is secured. Therefore, radial piezoelectric-magnetic fan (RPMF) produces larger average amplitude of fans which is 111%. The distribution of repulsive magnetic force in radial orientation is five times better than array orientation. The multiple fans is better to be arranged in radial orientation for its ability to produce larger repulsive magnetic force to oscillate the adjacent fans. Â It is found that at distance between magnets is 14 millimeters the average amplitude is largest at highest resonant frequency. In this study four magnetic fans were activated by a piezoelectric fan. The parameters under investigation are the distance between magnets and fans orientation. The purpose of this paper is to investigate the performance of multiple piezoelectric-magnetic fan and its significance in reducing temperature while enhance the heat transfer. By optimizing the repulsive magnetic force generated in between the magnets, the overall fans oscillate with significant average amplitude. An integration of piezoelectric fan with magnet is to widen the cooling coverage area with similar power consumption and cost of running a single piezoelectric fan. Piezoelectric fan, radial orientation, amplitude, magnetic fan AbstractĪpplication of piezoelectric fan in electronic cooling system has been proven that it is more efficient than natural convection with least power consumption and has high potential to replace existing rotary fan for its simplicity and longer life.
