Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and more particularly to a low-noise cooling tower. Background Art

[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 flow of water and air to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve the principles of 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. The device is generally barrel-shaped.

[0003] The patent document with publication number CN213599869U in the prior art provides a low-noise closed cooling tower. The device connects a vacuum pump through an exhaust valve to vacuum the cavity between the inner wall of the noise reduction shell and the outer wall of the cooling tower body, and uses the vacuum environment to hinder the propagation of noise, thereby reducing the noise generated by the cooling tower and improving the environmental protection of the device. When the sprinkler is spraying, water falls on the surface of the noise reduction sponge pad, effectively reducing the noise generation. At the same time, a water-guiding cotton net composed of several absorbent cotton threads is used to slowly guide the sprayed water to the water receiving cylinder at the bottom of the tower.

[0004] Although this device has many beneficial effects, the following problems still exist: during the use of this device, the noise reduction sponge absorbs water and drains away water slowly, which is inconvenient for the use of the cooling tower; secondly, the noise reduction effect of the device during use is not good enough by relying solely on vacuum, and needs to be improved. In view of this, we propose a low-noise cooling tower. Utility Model Content

The fan 3 and the hydraulic cylinder 602 are electrically connected to the external power supply. The utility model inputs hot water through the water inlet 2, opens the fan 3 to spray air from the air outlet 5 to cool the water, absorbs the cooled water through the noise reduction sponge 604, and reduces noise at the same time. The hydraulic cylinder 602 is opened to drive the pressure plate 603 to press down, thereby squeezing the noise reduction sponge 604 to accelerate the discharge of water. The cooling water slides down along the inclined surface of the drainage plate 605, flows into the water outlet 8 from the drainage groove 607, and is collected through the drain pipe 9.

[0029] Specifically, the noise reduction assembly 7 includes a soundproofing felt 701, with a sound-absorbing panel 702 fixed to one side of the soundproofing felt 701. Multiple sound-absorbing cotton columns 703 are fixed to the other side of the sound-absorbing panel 702, and a fiberboard 704 is fixed to the other side of the sound-absorbing panel 702.

[0038] Working principle: When the device is needed to be used for low-noise cooling, hot water is input through the water inlet 2, and air is ejected from the air outlet 5 by turning on the fan 3 to cool the water. The cooled water is absorbed by the noise reduction sponge 604, and the noise is reduced at the same time. The hydraulic cylinder 602 is turned on to drive the pressure plate 603 to press down, thereby squeezing the noise reduction sponge 604 to accelerate the discharge of water. The cooling water slides down the slope of the drainage plate 605 and flows into the water outlet 8 from the drainage groove 607. The cooled water is collected through the drain pipe 9 and then discharged through the insulation. The sound insulation assembly consisting of the sound felt 701, the sound absorbing panel 702, and the fiberboard 704, as well as the multiple sound absorbing cotton columns 703 arranged on the sound absorbing panel 702, form a chamber and produce a composite sound absorbing structure, which can better absorb the noise generated during operation.
