[0004] However, in actual use, although the above-mentioned cooling tower reduces the corrosion of the environment to the ladder by providing a slide assembly and a protective cover, thereby extending the service life of the ladder, the cooling tower is not provided with a silencer mechanism. In this case, if the cooling tower is used near a residential building, the noise it generates will affect the normal life of nearby residents. Utility Model Content

[0005] The utility model aims to provide a low-noise cooling tower to solve the problem of excessive noise in existing cooling towers.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-noise cooling tower, comprising an outer shell, a plurality of springs are fixedly connected to the bottom of the inner wall of the outer shell, a support plate is fixedly connected to the top of the spring, a damper is fixedly connected to the outer shell inside the spring, the top of the damper is fixedly connected to the support plate, a cooling tower body is arranged on the top of the support plate, an exhaust duct is arranged on the top of the cooling tower body, a silencer channel is arranged on the top of the outer shell at the exhaust duct, a plurality of sound insulation panels are staggered in the silencer channel, an air bag is arranged on the inner side wall of the outer shell, and a sound absorbing panel is fixedly connected to the top of the inner wall of the outer shell.

[0007] Preferably, an air pump is fixedly connected to one end of the top of the shell, and an output end of the air pump is connected to the airbag.

[0008] Preferably, a connecting tube is provided at the output end of the air pump, and the end of the connecting tube away from the air pump is connected to the airbag.

[0009] Preferably, a ventilation hole is provided at the top of the shell in the silencer channel.

[0010] Preferably, a water inlet pipe is provided at one end of the top of the cooling tower body, and one end of the water inlet pipe extends to the outside of the outer shell.

[0011] Preferably, a drain pipe is provided at the bottom of the cooling tower body, and an output end of the drain pipe extends to the outside of the outer shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model wraps a cooling tower body with an outer shell, thereby reducing the noise generated by the cooling tower body, and reduces the vibration generated when the cooling tower body is working by designing a spring and a damper, so that a part of the noise generated by the cooling tower body can be reduced. In addition, the vibration generated by the side wall of the cooling tower body can be reduced by the design of the air bag, so that the vibration generated by the side wall of the cooling tower body under the action of the air bag is difficult to be transmitted to the side wall of the outer shell, thereby avoiding the noise generated by the vibration of the side wall of the outer shell, and the noise transmitted to the top of the outer shell can be absorbed by the sound absorbing board, thereby further reducing the noise. Since the noise of the cooling tower body is mainly generated when the fan is working and the spray pipe is spraying, most of the noise will be transmitted to the outside through the exhaust pipe. Therefore, the noise transmitted from the exhaust pipe is eliminated by designing a silencer channel, wherein the noise transmitted from the exhaust pipe can be gradually blocked and absorbed by the sound insulation boards staggered in the silencer channel, so that when the noise passes through the silencer channel, there is not much volume.

[0021] In this embodiment, when the cooling tower body 5 is working, the spray pipe and the fan will generate a lot of noise, most of which will be transmitted to the outside through the exhaust pipe 6. Before being transmitted to the outside, the noise will pass through the silencer channel 7, in which a plurality of sound insulation boards 8 are staggeredly arranged. These sound insulation boards 8 will block and absorb the noise, so that the noise finally transmitted to the outside will not have too loud a volume. In addition, the design of the spring 2 and the damper 4 can reduce the vibration at the bottom of the cooling tower body 5, so that the bottom of the shell 1 will not vibrate, and thus will not Noise will be generated. In addition, the airbag 9 arranged on the inner side wall of the shell 1 can reduce the vibration of the side wall of the cooling tower body 5, thereby preventing the vibration generated by the side wall of the cooling tower body 5 from being transmitted to the side wall of the shell 1, thereby reducing the generation of noise. The sound-absorbing panel 10 arranged on the top of the inner wall of the shell 1 can absorb the noise transmitted to the top of the shell 1, thereby reducing the transmission of noise to the outside world. In this way, under the joint action of the spring 2, damper 4, airbag 9, sound-absorbing panel 10, silencer channel 7 and sound insulation panel 8, the noise generated when the cooling tower body 5 is working can be well reduced.

[0022] An air pump 11 is fixedly connected to one end of the top of the shell 1, and the output end of the air pump 11 is connected to the airbag 9. In this embodiment, the airbag 9 is inflated by the design of the air pump 11, so that when the airbag 9 is filled with air, it can have a good shock-absorbing effect, thereby achieving the purpose of reducing noise.

[0023] A connecting tube 12 is provided at the output end of the air pump 11 , and the end of the connecting tube 12 away from the air pump 11 is connected to the airbag 9 .

In this embodiment, since the spray pipe inside the cooling tower body 5 needs to spray water continuously when it is working, it is necessary to continuously supply water to the spray pipe. Therefore, the design of the water inlet pipe 14 facilitates the supply of water to the spray pipe.

[0026] A drain pipe 15 is provided at the bottom of the cooling tower body 5, and the output end of the drain pipe 15 extends to the outside of the outer shell 1. In this embodiment, since a lot of water sprayed by the sprinkler pipe will gather at the bottom of the cooling tower body 5, the design of the drain pipe 15 facilitates the discharge of these gathered water flows.

[0027] Working principle: When in use, when the cooling tower body 5 is working, the spray pipe and the fan will generate a lot of noise, most of which will be transmitted to the outside through the exhaust pipe 6. Before being transmitted to the outside, these noises will pass through the silencer channel 7, in which a plurality of sound insulation panels 8 are staggeredly arranged. These sound insulation panels 8 will block and absorb the noise, so that the noise finally transmitted to the outside will not have too loud a volume. In addition, the design of the spring 2 and the damper 4 can reduce the vibration of the bottom of the cooling tower body 5, so that the bottom of the shell 1 will not vibrate, and thus no noise will be generated. In addition, when the cooling tower body 5 is working, the air When the pump 11 is turned on, air will enter the airbag 9 through the connecting pipe 12 under the action of the air pump 11. When the airbag 9 is filled with air, the vibration of the side wall of the cooling tower body 5 can be reduced, thereby avoiding the vibration generated by the side wall of the cooling tower body 5 from being transmitted to the side wall of the outer shell 1, thereby reducing the generation of noise. The sound-absorbing panel 10 arranged on the top of the inner wall of the outer shell 1 can absorb the noise transmitted to the top of the outer shell 1, thereby reducing the transmission of noise to the outside world. In this way, under the joint action of the spring 2, damper 4, airbag 9, sound-absorbing panel 10, silencer channel 7 and sound insulation panel 8, the noise generated when the cooling tower body 5 is working can be well reduced.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
