[0002] The function of a cooling tower is to exchange heat between the cooling water carrying waste heat and the air inside the tower, so that the waste heat is transferred to the air and dissipated into the atmosphere. The cooling tower uses water as a circulating coolant and then sprays the water inside the cooling tower through a spray mechanism.

[0003] However, the existing spraying mechanisms are generally fixed and can only spray a specified range during use, resulting in spraying dead angles. Therefore, the filler inside the cooling tower cannot be covered in all directions, and the flexibility of the use of the spraying mechanism is reduced while reducing the cooling effect of the cooling tower; secondly, the impact force on the filler surface will be uneven during spraying, and some areas of the filler will be severely worn, thereby shortening the service life of the filler in the cooling tower. Utility Model Content
