Abstract:

In order to explore the performance of the multistage pin-mesh ionic wind cooling system and optimize the design for the multistage ionic wind heat dissipation device, a multistage pin-mesh ionic wind cooling system device was proposed to study the effect of multistage number, stage clearance, and discharge voltage on the maximum wind velocity of the ionic wind and the heat dissipation temperature drop of the heating plate. The results show that at the same voltage, the multistage heat dissipation performance is better than the single-stage, which can reduce the 11 W heating plate to a lower temperature and obtain a larger maximum wind velocity of the ionic wind. When the maximum wind velocity of the ionic wind reaches the maximum value, it does not mean that the heat dissipation performance is the best, because the optimal heat dissipation performance can be achieved when the average wind velocity reaches the maximum value. The multistage device using the pin-mesh integrated structure has a maximum wind velocity of 2.6 m/s, which can reduce the temperature of the 11 W heating plate to about 90℃ and the temperature drop to about 105℃, while the single-stage can only drop to 110℃ and the temperature drop is about 85℃.

摘要：

为探究多级针-网式离子风散热系统的性能和针对多级离子风散热装置进行优化设计，提出一种多级针-网式离子风散热系统装置，研究多级级数、级间隙、放电电压对离子风最大风速和发热片的散热温降的影响。结果表明，在相同电压时，多级比单级散热性能更好，能把11 W的发热片降低到更低的温度，并获得更大的离子风最大风速。多级装置离子风最大风速可达2.6 m/s，能把11 W的发热片温度降到90℃左右，温降可达105℃左右，而单级只能降到110℃，温降约85℃。
