摘　　要：本文利用计算流体力学软件对火电厂中直接空气冷凝器的换热情况进行数值模拟。并根据计算结果提出增加空冷平台最外一圈风机功率及在空冷平台下方修建挡风建筑以提高空冷平台换热效率的可行性建议。The major nork of this paper is applying commercial CFD software to simulate heat dissipation of direct air-cooled condenser in power plants. According to the result of compulation, we conclude that increasing power of outer fans and using mind block underneath condenser flat can enhance heat exchanging efficiency.
