In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inner", "outer", etc. indicate the orientation or position relationship that the product is usually placed when using, and are based on the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element that is referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The water cooling tower is a device which uses water as a circulating coolant, absorbs heat from a water circulating system and discharges the heat to the atmosphere so as to reduce the water temperature; the cooling is completed by the evaporation process of water, and the cooling water can be continuously recycled. The cooling tower sprays hot water in a system onto the surface of a filler in a spraying mode, the hot water is in contact with flowing air, a heat exchange effect is generated between the hot water and cold air, meanwhile, part of the hot water is evaporated, the heat of the hot water is taken away by evaporated water vapor due to the heat absorption effect of evaporation, so that the temperature of the original hot water is reduced and cooled, the cooled water falls into a water tank, and the cooled water is conveyed into a heat exchanger by using the pressure provided by a water pump and absorbs the heat. Thus, the purpose of heat transportation is achieved.

As shown in fig. 1 and 2, the water cooling tower includes a tower body 100, a spraying system 200, a water cooling tank 300 and a packing layer 400. The tower body 100 is also internally provided with a motor 50 and a fan 60, wherein the motor 50 mainly provides power for the fan 60, the fan provides power for the air flow of the fan 60, and the material is light, has high mechanical strength and is free of cracks, gaps and burrs.

The filler layer 400 is filled with a heat-dissipating filler, preferably a glass fiber filler. The spraying system 200 enables water to be uniformly dispersed on the filler, the better the water dispersion effect is, the better the effect of the cooling tower is, the contact area of the water and air can be increased by the filler, so that the water and the air are fully contacted, and the larger the contact area is, the better the cooling effect is; in the process of exchanging hot water and air entering the cooling tower, not only heat exchange but also mass exchange, namely evaporation of moisture, so that water of the water cooling tower is continuously reduced along with circulation of cooling water.
