Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a noise reduction cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant, absorbs heat from a system and discharges it into the atmosphere to lower the water temperature. A countercurrent closed cooling tower places a tubular cooler inside the tower, and ensures the cooling effect through heat exchange between circulating air, spray water and circulating water.

[0003] When an existing noise reduction cooling tower is in use, air flows through the cooling filler and out of the heat dissipation port to cool the hot water. The cooled water then drips from the cooling filler to the bottom of the body for collection. When the water falls on the water surface, there is a sound of water hitting the water surface. The cooling tower makes a lot of noise when running at night, and it is easy to fail to meet the noise control standards, which affects the environmental protection acceptance.

[0004] The existing patent (publication number: CN219624525U) is a noise reduction cooling tower, comprising a cooling tower body, a mounting frame and a silencer block; the mounting frame is used to be installed at the bottom of the cooling tower body; the silencer block is installed on the mounting frame; the silencer block is penetrated by a plurality of curved silencer channels, and the lower half of the silencer block is immersed in the water at the bottom of the cooling tower body through the curved silencer channels. Based on this, the water can be guided to slide into the bottom of the cooling tower body at a certain angle to weaken the kinetic energy of the water before entering the water. On the other hand, the noise generated by the water when it hits the water surface will hit back and forth in the curved silencer channel to weaken the noise energy, reduce the operating noise of the cooling tower, and improve the problem of the noise control of the cooling tower not meeting the standards and affecting the environmental protection acceptance.

[0005] In view of the above problems, existing patents have provided solutions. However, when the cooling tower is in use, the noise source is not only the noise generated by the water hitting the water surface, but also the noise generated by the fan when it is working. If only the noise generated by the water flow is processed, the noise cannot be well controlled, which affects the environmental protection acceptance.

[0006] Therefore, a noise reduction cooling tower is proposed. Utility Model Content
