摘　　要：随着直接空冷技术的不断发展,环境风影响空冷凝汽器换热的问题越来越受到人们的关注。针对该问题,学者们采用风洞模拟和数值研究方法进行了研究,并取得了一些研究成果。综合分析这些研究成果后得出的结论是:横向风和空冷平台的结构是影响空冷凝汽器换热的主要原因,这种影响主要体现在风机入口温度的升高和风机出力的降低2个方面;挡风墙、防风网、导流装置等可以有效改善空冷凝汽器的换热性能。分析了环境风对空冷岛换热影响的机理,并展望该课题的发展趋势和前景。Along with the development of air-cooled technology, the influence of environmental wind on the heat transfer of air-cooled condenser has drawn more and more attention. By the method of wind tunnel simulation and numerical study, the research of this problem has achieved a number of research results： the crosswind and the structure of the air- cooled platform are the main factors affecting the heat transfer of air-cooled condenser, which are mainly reflected in the entrance temperature increase and output decrease of fan. Wind-break wall, windproof net and guiding device could effectively improve the heat transfer performance of air-cooled condenser. Finally, the influence mechanism of environmental wind on air-cooled island was analyzed, and its development trend and prospect were studied.
