Abstract  

A needles-net structure ionic wind generator was designed for high power LED chip heat dissipation. The mechanism of ionic wind generation under positive (negative) corona discharge and enhanced heat transfer was analyzed. Experiments were conducted to analyze the change rules for LED chip case temperature, the thermal resistance and the mean heat transfer coefficient under different working conditions. Results show that the cooling performance of negative corona discharge ionic wind is superior to the one of positive corona discharge. The system has smaller thermal resistance but bigger mean heat transfer coefficient. The cooling effect of the system is more obvious when the needles are located around the LED chips. The ionic wind increases proportional to the overvoltage but grows in inverse proportion to the discharge distance. The designed ionic wind generator can realize the heat dissipation effect more close to a cooling fan, and has the advantages of small vibration, no noise compared to a cooling fan.

离子风强化大功率LED散热的实验研究

设计“针-网”结构的离子风发生器,用于大功率LED芯片散热.分析正、负电晕放电离子风的产生及强化传热机理,通过实验研究不同工况下,芯片引脚温度、系统总热阻、平均换热系数等参数的变化规律.研究结果表明：相同条件下,负电晕放电离子风的散热效果优于正电晕放电,系统总热阻更小,平均换热系数更大;当放电针分布于LED芯片附近时,系统的散热效果更显著;离子风速度随过电压增加而线性增加,并与放电间距成反比;设计的离子风散热系统具有与压电风扇相接近的散热效果,但无运动部件,工作噪音小.
