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
