摘要
Based on the layout of the power plant';s main buildings and air cooling towers of a typical MW indirect air cooling sets, the flow and temperature fields of the cooling air were presented by CFD simulation. The influences of the set';s heat load, ambient temperature, wind speed and direction upon the inlet air velocity of air-cooled radiator were investigated. The results show that the windward air velocity is the highest and the cooling air temperature is the lowest, thus the cooling effect is the best for the air-cooled radiator units locating in the upward of the wind. However, for the side air-cooled radiator units the windward air velocity is the lowest and the cooling air temperature is the highest, thus the cooling effect is the worst. The flow rate of the cooling air of the air-cooled radiator increases with the set';s heat load increasing and decreases with the ambient temperature and wind speed increasing. The operation characteristics of air-cooled radiator are also affected by the wind directions.
