本文介绍了一种用于大功率电子芯片冷却的EHD空气泵的设计、优化和制造。根据对离子风流动起重要作用的产生电场的特性，选择并研究了合适的高压电极配置。为此，使用专用软件进行有限元分析。研究了电场强度、风速、电流和功耗等关键设计参数。制作了两种不同的实验室样机，并对其性能进行了实验评估。这一过程导致了最终原型的制造，然后作为用于冷却高功率密度电子芯片的典型风扇的替代品进行测试。为了帮助实现这一目标，设计并建造了一个实验热测试装置，以模拟个人计算机的可变功率CPU核心的大小。在参数研究的基础上，制作了实验用的单级EHD泵，其优化设计能够在10.5kV的工作电压下提供51cfm的空气流量。最后，对理论和实验结果进行了评价，并提出了潜在的应用前景。
This paper presents the design, optimization and fabrication of an EHD air pump intended for high-power electronic chip cooling applications. Suitable high-voltage electrode configurations were selected and studied, in terms of the characteristics of the generated electric field, which play an important role in ionic wind flow. For this purpose, dedicated software is used to implement finite element analysis. Critical design parameters, such as the electric field intensity, wind velocity, current flow and power consumption are investigated. Two different laboratory prototypes are fabricated and their performances experimentally assessed. This procedure leads to the fabrication of a final prototype, which is then tested as a replacement of a typical fan for cooling a high power density electronic chip. To assist towards that end, an experimental thermal testing setup is designed and constructed to simulate the size of a personal computer's CPU core of variable power. The parametric study leads to the fabrication of experimental single-stage EHD pumps, the optimal design of which is capable of delivering an air flow of 51 CFM with an operating voltage of 10.5 kV. Finally, the theoretical and experimental results are evaluated and potential applications are proposed.
