Abstract: FLUENT was used to simulate the heat exchange in water cooling tower of the power plants to overcome the difficult of heat transfer simulation in physical experiments. The traditional cooling tower and the tower employing the“flow spiral making technique”, were studied under different environment wind velocities. The operations of the two kinds of towers were compared. The results indicate that the tower employing the“flow spiral making technique”owns more ability to resist environment wind and is more efficient than the traditional one.

Key words: cooling tower, spiral making, flow conduct board

摘要： 使用 FLUENT 软件, 对水冷火电厂的水冷塔换热进行了数值模拟, 解决了物模实验难 以模拟热力因素的困难。同时还对采用 “空气涡流导引装置技术 ”的水冷塔和传统水冷塔, 在不同环境风影响下的换热效率进行了对比。结果表明, 采用“空气涡流导引装置技术”的水冷塔换热效果优于传统水冷塔, 抵抗大风的能力更强。
