The utility model discloses concrete theory of operation:

high-temperature hot water to be cooled enters the cooling tower from the water inlet 9 through the water inlet flange and is sprayed on the filler 7 by the spraying system 8.

The cold air entering the cooling tower contacts with water in the filler 7, the water evaporates to absorb heat, and the air obtains the heat in the water and the evaporated water amount and then becomes saturated air with high temperature and high humidity.

Saturated air in the tower enters the second air duct 14 of the fog dispersal water saving module 1, and carries out condensation heat exchange with cold air outside the tower entering the first air duct 13 of the fog dispersal water saving module 1, and the condensed water flows back to the water accumulation basin 5.

The first air duct 13 is communicated with the outside, the schematic view of the opening of the air inlet of the first air duct 13 on the top of the tower is shown in fig. 2, the motor 3 drives the fan 3 in the air duct 4 to rotate, suction force is generated, and outside cold air flows into the first air duct 13.

The cold air outside the tower is heated by the high-temperature and high-humidity air flow in the tower in the first air duct 13, and is mixed with the hot and humid air flow in the tower after being condensed and cooled, the relative humidity is further reduced, the air is discharged out of the tower by the fan 2, and the air discharged out of the tower can not generate fog due to the cold air outside the tower.

The cold air inlet structure at the top of the tower is illustrated in detail in fig. 3-4, and consists of a fixed grid plate 102 at the lower level and a slidable movable grid plate 102 at the upper level. In a winter mode of operation where defogging is desired, the movable grid plate 102 may be slid to a position where the openings are open to allow cool air to flow in. In summer, the fog dispersal and water conservation function is not needed any more, the movable grid plate 102 can be moved rightwards to close the cold air inlet, and the air volume passing through the fan is all from the air volume passing through the filling area.
