Abstract

An ionic wind cooling method based on corona discharge theory was presented to meet the thermal demand of high power LED. The electrical properties of corona discharge were studied through experimental measurement. The effect of discharge voltage on the refrigerating performance was researched

as well as the change laws of temperature drops with discharge power. The experimental results indicate that the negative corona can generate ionic wind at lower voltage and result in siganificant cooling at the same electrode gap comparing with positive corona.The corona current square root displays a good linear relationship to the applied voltage.The optimal refrigerating performance is attained at 1.5 W power and 10 mm electrode gap.
