摘　　要：随着卧室冰箱等高静音要求的应用场景出现,使用机械风机散热的半导体冰箱由于存在转子旋转噪声及振动噪声,已无法满足用户需求。离子风机是利用电晕放电产生的离子加速运动带动空气流动来实现散热的,无任何运动部件,可以实现高效静音散热。对影响离子风机风速的各项参数进行了设计实验,当针电极曲率半径为0.05 mm、网电极线径为0.6 mm、线电极孔径为8 mm、相邻针电极间距为16 mm,针-网电极间距为12 mm时,输入电压20 kV,离子风机风速可达2.3 m/s,将其安装在90 L半导体冰箱的热端上进行了散热实验,箱内温度仅比使用轴流风机散热的半导体冰箱高1.22℃,离子风机基本达到了轴流风机的散热效果。With the emergence of application scenarios with high noise requirements such as bedroom refrigerators, semiconductor refrigerators that use mechanical fans to dissipate heat can no longer meet user needs due to rotor rotation noise and vibration noise. The ion fan uses the accelerated motion of ions generated by corona discharge to drive the air to dissipate heat. It has no moving parts and can achieve effcient and silent heat dissipation. Through design experiments on various parameters affecting the wind speed of the ion fan, when the needle electrode curvature radius is 0.05 mm, the wire diameter of the mesh electrode is 0.6 mm, the wire electrode aperture is 8 mm, and the distance between adjacent needle electrodes is 16 mm, the needle-mesh electrode When the spacing is 12 mm, the input voltage is 20 kV, and the wind speed of the ion fan can reach 2.3 m/s. It is installed on the hot end of a 90 L semiconductor refrigerator to conduct a heat dissipation experiment. The temperature inside the box is only higher than that of a semiconductor refrigerator that uses an axial fan to dissipate heat 1.22℃, the ion fan basically achieves the heat dissipation effect of an axial fan.
