Abstract:

Spray cooling is one of effective and efficient cooling method, which is widely applied to the thermal management of high-power density electronics. In recent years, spray cooling has attracted great attention, and its heat transfer capacity has been significantly improved. Particularly, the development of new micro/nano surfaces has dramatically boosted the heat transfer of spray cooling, enriching the enhanced mechanisms of spray cooling. Herein, this review comprehensively summarizes the recent achievements of spray cooling and discusses the enhanced mechanisms. Furthermore, the effects of heat transfer surfaces, working fluids and parameters of nozzles, etc, on spray cooling have been systematically discussed. Finally, this paper further explores the mechanism of spray cooling to suppress the Leidenfrost effect, and looks forward to the future research direction of spray cooling.

Key words: spray cooling, heat transfer, micro/nano-structure, functional engineering surface, Leidenfrost effect

摘要:

喷雾冷却是一种高效的散热手段,广泛应用于高热通量电子元器件的热管理。近年来,喷雾冷却引起了极大的关注,其换热能力得到了显著的提升。特别地,新型微纳米表面的开发极大地促进了喷雾冷却传热的发展,丰富了喷雾传热强化的机理研究。因此,本文全面系统地总结了喷雾冷却的最新研究成果,讨论了喷雾换热的强化机理,从传热表面特性,工作介质以及喷嘴参数等多个方面讨论了喷雾冷却换热的关键影响因素。最后,进一步探讨了喷雾冷却抑制Leidenfrost现象的机制,并对喷雾冷却未来研究方向进行了展望。
