Abstract:

 

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.

Key words: environmental wind, air-cooled island, fan temperature, fan output, improving method
