Abstract：An ionic wind generator of different discharge and grounding electrode was designed in order to research the effect of electrode structure on the properties of ionic wind.Series of experiments were conducted to get a optimized structure, and this solution was also used to enhance the high power LED heat dissipation.The results show that the best configuration form for different discharge electrodes is 1×11 needle-arrayed and 1cm electrode distance of line-arrayed.Mesh grounding electrode is proved to be more effective than orifice-plate grounding electrode, especially 20-mesh grounding electrode, and its ionic wind speed reach up to 1.79 m/s.Moreover, its maximum cooling rate on LED pin was 44 ℃.
