摘要

喷雾冷却是高功率电子器件冷却领域最具有发展前景的散热方式。利用在去离子水中添加不同浓度低醇类（乙醇、正丁醇）添加剂以提升喷雾冷却换热性能的方法，搭建了喷雾冷却实验平台并就添加剂浓度对传热特性的影响进行了实验研究。实验结果表明在去离子水中加入乙醇和正丁醇，存在强化换热的最佳添加剂浓度。在还未达到最佳浓度值之前，添加剂浓度越高，喷雾冷却换热效果越好。乙醇的最佳浓度为4%，正丁醇的最佳浓度为0.5%。

Abstract

Spray cooling is the most promising cooling method in the field of high-power electronic device cooling. Different concentrations of low alcohols (ethanol and

-butanol) were added into deionized water to improve the heat transfer performance of spray cooling. The experimental system was established and the effect of concentration on heat transfer characteristics was investigated. The results reveal that an optimal concentration exists by adding low-alcohol additives into deionized water. The performance of spray cooling is gradually enhanced with increasing concentration before the optimum concentration. The optimum concentration of ethanol is 4% and the optimum concentration of

-butanol is 0.5%.
