本文介绍了电流体动力学 (EHD) 和静电力对池沸腾临界热通量影响的实验研究结果。选择沸点为 59.8 °C 的 HFE-7100（3M Ltd.）电介质液体作为工作流体。为了通过施加低电压产生高电场，通过微机电系统技术制造了具有平面梳齿阵列的微图案电极。电极在电极对之间具有10个宽度为400μm的狭缝，以便通过EHD效应从传热表面去除蒸汽泡。通过不同的施加电压来评估用该电极制造的冷却装置。结果，电压的应用增强了传热。
This paper describes the results from an experimental study of the effect of an electrohydrodynamic (EHD) and an electrostatic force on the critical heat flux in pool boiling. The dielectric liquid of HFE-7100 (3M Ltd.), which has a boiling point of 59.8 °C, was selected as a working fluid. In order to generate high electric fields with the application of low voltages, a micropatterned electrode with an array of planar comb fingers was made by microelectromechanical systems technology. The electrode had ten slits whose width was 400 μm between electrode pairs so as to remove vapor bubbles from a heat transfer surface by the EHD effect. A cooling device fabricated with the electrode was evaluated by different applied voltages. As a result, the application of voltage enhanced heat transfer.
