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。
With the continuous development of direct air cooling technology, the issue of environmental wind affecting the heat transfer of air-cooled condensers has drawn more and more attention. In response to this problem, scholars have conducted research using wind tunnel simulation and numerical methods and have made some achievements. After the comprehensive analysis of these research results, it is concluded that the structure of horizontal wind and air-cooled platform is the main reason that affects the heat transfer of the air-cooled condenser. This effect is mainly reflected in the increase of inlet temperature of the fan and the decrease of fan output by 2 Aspects; wind walls, wind screens, diversion devices, etc. can effectively improve the air-cooled condenser heat transfer performance. The mechanism of the influence of the ambient wind on the heat transfer of the air-cooled island is analyzed, and the development trend and prospect of the topic are also expected.
