Abstract

This paper focuses on the flow and heat transfer characteristics of a cooling system that combines thermoelectric cooling technology with ion wind technology. Through experimental exploration and data analysis, the factors affecting the performance of the sawtooth-plate ion wind were first investigated using the orthogonal experimental method. Particle Image Velocimetry (PIV) was employed to visualize the internal flow field and investigate the impact of voltage and plate spacing on the performance of the ion wind generator with a mesh and a parallel plate receiving electrode. Lastly, the heat transfer characteristics of the standalone thermoelectric cooling system and the coupled system were compared. The study found that voltage has the greatest impact on the performance of the ion wind, followed by the spacing of the parallel plate electrodes. Compared to the standalone thermoelectric cooling system, the temperature drop of the heat source in the coupled system increased by 6.7%, and the COP increased by 7.9%, proving that the coupled system has significantly improved heat transfer performance.

热电制冷和离子风耦合冷却系统的流动和传热特性研究

本文重点研究了热电冷却技术与离子风技术相结合的冷却系统的流动和传热特性。通过实验探索和数据分析，首先采用正交实验法研究了影响锯齿板离子风性能的因素。采用粒子图像测速仪（PIV）对内部流场进行可视化，并研究了电压和板间距对网状和平行板接收电极离子风发生器性能的影响。最后，比较了独立热电冷却系统和耦合系统的传热特性。研究发现，电压对离子风性能的影响最大，其次是平行板电极的间距。与独立热电冷却系统相比，耦合系统中热源的温降增加了 6.7%，COP 增加了 7.9%，证明耦合系统的传热性能显著提高。
