Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling towers, in particular to an energy-saving and noise-reducing cooling tower. BACKGROUND

[0002] A cooling tower is a device used to reduce the heat generated by industrial equipment or buildings, commonly used in air conditioning, power plants, chemical plants and other industries, by contacting hot water with air to reduce water temperature and then emitting heat to the air.

[0003] During use, the cooling tower needs to spray hot water to ensure uniform contact between the hot water and the air, thereby achieving good heat dissipation.

[0004] As in the prior art, a cooling tower is disclosed in Chinese Patent No. CN111981866B, which has a first spray layer and a second spray layer inside the tower body for spraying circulating water. A heat exchange layer is provided between the first spray layer and the second spray layer. The heat exchange layer includes a heat exchange module, which has a first flow channel for wet hot air to flow through and a second flow channel for dry cold air to flow through. The upper end of the first flow channel is open to allow wet hot air to flow out and circulating water sprayed by the second spray layer to flow in. This design improves the fog dissipation effect and cooling effect of the cooling tower, and makes the heat exchange module function similarly to the filler layer.

[0005] Similarly, in the prior art, Chinese Patent No. CN105004197A discloses a cooling tower, which has an air inlet and an air outlet on the cooling tower body. The fan is arranged at the air inlet of the cooling tower body, and the water inlet pipe is arranged inside the cooling tower body. The filler is located between the nozzle and the air inlet. The water baffle is arranged inside the cooling tower body and below the water inlet pipe, and the nozzles are evenly distributed on the water baffle. The design of installing the traditional nozzle directly on the water inlet pipe is changed to arranging the nozzle on the water baffle. Compared with the water inlet pipe, the water baffle can install more nozzles. Even if some nozzles are blocked, it will not significantly affect the quality of the water mist, thereby ensuring the cooling effect of the cooling tower.

[0006] From the above materials, it can be seen that the prior art usually uses a spray head to spray hot water and contact it with the filler, thereby achieving heat dissipation. However, in actual use, the hot water sprayed by the spray head directly falls on the filler, and the contact between the hot water and the air is not sufficient due to the short time, thereby resulting in unsatisfactory heat dissipation and increased overall energy consumption of the device.
