摘　　要：喷雾冷却是解决电子元器件等高热流密度散热问题的关键技术。综述了在纯工质中添加纳米颗粒、表面活性剂、可溶性盐和气体以及醇类等添加剂对喷雾冷却换热性能的影响,介绍了不同类型添加剂影响换热的机理和限制换热的因素,并提出了一些可行的解决方案。指出了对含有添加剂的喷雾冷却的研究方向和应用前景。Spray cooling has excellent heat exchange performance. It is the key technique in the field of electronic cooling which requires low and uniform surface temperature and high heat flux. The influences of circulatory refi＇igerant with addictives on spray cooling heat transfer are summarized, the limiting factors of these addictives to further improvement of heat transfer efficiency are noted and some solutions are put forward. The addictives mainly include nano-particles, surfactants, dissolved gases and salts and alcohol. Last, some research directions are pointed out and a prospect forecast is gived.
