摘　　要：喷雾冷却作为一种解决高功率激光器散热需求的技术得到越来越多的关注。结合近几年的研究工作,综述了喷雾冷却技术的研究现状。针对高功率激光器的散热需求,主要从传热机理、影响因素、温度均匀性方面进行阐述,分析了存在的问题。提出将制冷系统和喷雾系统结合、R600a等制冷剂为冷却剂的冷却方案,设计了气助式制冷喷雾冷却系统,分析了适用于制冷喷雾冷却系统的工质,提出了喷雾冷却技术在高功率固体激光器散热中的发展方向。As an efficient cooling method for high power lasers, spray cooling gets more and more attentions. The progress in spray cooling technology is reviewed. Emphasis is placed on the heat transfer mechanism, the influencing factors of heat transfer capability and the temperature uniformity of heat transfer surface. The solutions to solve the existing problems are proposed, such as the integration of refrigeration system and spray system, R600a and other eco-friendly refrigerants with high latent heat, and the system of refrigeration spray cooling with air assisted atomizer and appropriate coolants for the system. Future trends of spray cooling for high power solid-state laser is also discussed.
