This study is to design and test vortex fan. The vortex fans usually apply to electronics cooling and heat dissipation. In this research, the effect analyzed with changing space of vortex fan and fin. Furthermore, to simulate temperature distribution of the vortex fan and fin, is analyzed by CFDeisgn software. By comparing the results of simulation and experiment can prove that the performance and lifetime of the vortex fan are highly improved.In the experimentation, the distance between vortex fan and fin is set by 0-8mm, and the heating power is fixed to 50W. The fan of optimal design and analysis are to investigate the thermal conductivity from experiments and simulations data.
