 摘要：直接空冷系统的总体布置主要考虑环境大风对系统散热能力的影响，即热风回流和风机效率下降的问题。空冷凝汽器周围的风环境状况必然会对空冷凝汽器效率和正常运行有很大影响。随着平台高度的增加，热风回流对空冷系统散热效率降低的影响减少，系统运行效率提高，系统抵御大风的能力增强，安全运行稳定性提高，运行费用降低，然而，整个空冷系统的初投资相应增加，因此，在工程设计中，需要从系统运行费用、初投资等技术经济角度综合进行比较，确定最优平台高度。 关键词：直接空冷系统；平台高度；空冷凝汽器；传热性能；热风回流 Abstract: For general layout of the direct air cooling system, affect of the environment gale on radiating efficiency of the system shall be considered, which is consider reflux of hot air and efficiency of the fan is lowered due to the environment gale. The environment wind around the air cooling condenser has a bigger influence on the efficient of air cooling condenser and the normal of the whole system. With increasing platform height, hot air back to the cooling system reduces the impact of reduced efficiency, and the efficiency of the system running will be improved, system ability to withstand strong winds will be strengthened, the stability of safe operation will be improved, operating costs will be reduced. On the other hand, investment of the whole air cooling system in early will be increased. So, in engineering design the optimal platform height need to be determined by comprehensive technical and economic point of comparison between the system operating costs and investment in the beginning. Key words: Direct Air Cooling System, Platform Height, Air Cooling Condenser, Heat Transfer Performance, reflux of hot air
