| Abstract |
The electrodynamics(EHD) ionic wind cooling system is very efficient in cooling of electronics, compared to the standard cooling systems. However, standard ionic wind generator is only composed of a corona electrode and an induction electrode, to be limited in improving the ionic wind velocity. In order to improve the ionic wind velocity, we applied accelerating electrode to a conventional ionic wind generator. and investigated the effect of change in shapes of induction and accelerating electrode pairs. Applying accelerating (mesh or ring) electrodes to a shape of corona (needle) electrodes and induction (mesh or ring) electrodes in an ionic wind generator increase the ionic wind velocity according to application of voltage to the accelerating electrodes. Also, increase rate of ionic wind velocity was higher when the induction electrodes were rings and the accelerating electrodes were mesh. |
