Spray cooling is characterized by high heat exchange capability, small temperature difference between working fluid and heated surface, low coolant mass flux, low working fluid consumption, without boiling hysteresis and contact thermal resistance between working fluid and heated surface. In recent years, its application prospect has gotten widely attention in the field of electronic cooling. However, there is a lack of a uniform theory of spraying cooling for industry applications. The principle and characteristic of inclined spraying cooling were introduced, and the significant achievements in recent years on the effect of spray inclination angels to heat transfer were reviewed. The investigation results on inclined spraying cooling were summarized based on time sequence, including the spray nozzle movement orbits, the boundary curvilinear equation of the spraying action area with different spray inclination angles and the ways to further improve the heat transfer efficient. In addition, the difference of the existing experimental conclusions was analyzed emphatically and the available conclusions on the inclination angles were given. The advances in the applications of spray inclination were described briefly, and the key problems that have not been solved were discussed.%喷雾冷却有换热能力强、工质与热表面温差小、冷却工质流量小、工质耗量低、无沸腾滞后性、工质与固体表面之间无接触热阻等优点.近年来,其在电子冷却领域的应用前景正得到众多研究者的关注.但目前仍缺乏统一的理论来指导实际应用.本文在介绍了倾斜式喷雾冷却工作原理及特点的基础上,综述了近年来国内外学者关于喷雾倾角对喷雾换热的影响所开展的研究,按时间顺序总结了倾斜式喷雾冷却的研究成果,包括喷嘴的运动轨迹,不同喷雾倾角下喷雾区域的边界方程以及进一步提高喷雾效率的途径.针对已有实验结论的互异性做了重点分析,并给出了关于喷雾倾角的有用结论.简单地阐明了倾斜喷雾的优势,并指出了目前还没有解决的关键问题.
