[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system.

[0003] For example, Chinese patent application No. 202221896332.9 discloses a low-noise cooling tower.

[0004] In the above scheme, the hot water storage tank is separated from the tower body, and the hot water is sprayed only once, which may not necessarily reduce the temperature of the hot water well. In order to solve the above problems, we designed a low-noise cooling tower. Utility Model Content

[0030] See also Figure 2 A vacuum chamber 17 is provided in the cooling tower shell 1, and a second sound-absorbing cotton 18 is fixedly connected to the side wall of the vacuum chamber 17. The vacuum chamber 17 can block the sound from propagating outward, and the second sound-absorbing cotton 18 can further eliminate the noise.

[0031] See also Figure 2 The upper side wall of the material plate 8 is fixedly connected with a first sound-absorbing cotton 9, which can reduce the noise when water falls.

[0032] See also Figure 2 A plurality of guide plates 5 are fixedly connected to the inner side walls of the plurality of air outlet pipes 4. The guide plates 5 are all arranged in an inclined shape. The guide plates 5 are made of heat-absorbing material, which can cool the steam in the hot air into water and finally flow into the tower, thereby reducing the moisture flowing into the air and reducing waste.

[0033] See also Figure 2 The multiple air outlet pipes 4 are all arranged in a curved shape, and the air collides in the curved air outlet pipes 4.

[0037] The working principle of the utility model is as follows: when in use, hot water is injected into the bottom of the cooling tower shell 1 through the water inlet pipe, the water pump 16 draws out the hot water at the bottom of the cooling tower shell 1, transports it into the water uniforming pipe 6, and then sprays it onto the material through the water spray head 7, and starts the fan 3 at the same time. The fan 3 can allow external air to enter the tower through the air inlet 10, and the air contacts the sprayed water to exchange heat, thereby reducing the temperature of the water. The cooled water falls to the bottom of the reaction tower and can be neutralized with the hot water at the bottom to further reduce the temperature of the hot water, and then is pumped out by the water pump, repeating the previous step, and repeatedly utilizing the cooled water to neutralize the hot water, thereby improving the cooling effect and shortening the cooling time. The fan 3 blows the hot air to multiple outlet pipes 4, dividing a stream of hot air into multiple streams, which can reduce the noise during air flow, and then the air collides with multiple guide plates 5 in the curved outlet pipe 4. The impact force of air flow can be reduced, so that the kinetic energy of air is greatly reduced when it is discharged from the air outlet, and the wind noise generated during discharge can be reduced. The guide plate 5 is made of heat-absorbing material, which can make the steam in the hot air cool down and become water, and finally flow into the tower, reducing the moisture in the air and reducing waste. The first silencer cotton 9 can reduce the noise when water falls, and the vacuum chamber 17 can block the sound from propagating outward, and the second silencer cotton 18 can further eliminate the noise.
