摘　　要：通过模拟分析大风及高温天气对某4×350 WM火电机组SCAL间接冷却塔换热效率的影响,提出在间冷塔周围加装外侧挡风墙并进行实际安装,计算分析及实践的结果表明:间接冷却水塔合理增加挡风墙,能有效降低大风及高温天气对换热效率的影响。Through simulation and analysis of the effect of strong wind and hot weather on the heat exchange efficiency of the SCAL indirect cooling tower of 4 × 350 WM thermal power unit, it was put forward and implemented to add a lateral wind break wall around the cooling tower. Both calculation analysis and practice results showed that reasonably adding wind wall to indirect cooling tower can effectively reduce the effect of trade wind and hot weather on heat exchange efficiency.
