Abstract

In order to explore the performance of the wire-plate ionic air cooling device, the mathematical and physical model of the device was established to simulate and calculate the influence of different channel lengths on the flow state and heat transfer effect of the ionic air cooling model. The results show that the airflow in short channel forms a large eddy due to electro-hydro Dynamics (EHD) effect and the air velocity near the hot wall is greatly increased, and the longer channel is easy to lead to the generation of multi-vortex structure, which is not conducive to heat dissipation. The convective heat transfer coefficient of the wall to be cooled at different electrode voltages and inlet velocity was comprehensively compared. The ionic-wind’s heat transfer effect was the best when the channel length was 13mm, which provided a reference for the size optimization of ionic wind cooling devices.
