[0039] The working principle and use process of the utility model are as follows: when the air-cooled water chiller set body starts to operate in use, the compressor in the air-cooled water chiller set body compresses refrigerant gas into high-pressure superheated vapor, and discharges into a condenser, at this time, the high-temperature and high-pressure refrigerant gas in the condenser needs to exchange heat with air to realize cooling and liquefaction, and this process starts the collaborative work of each part of the self-adaptive noise reduction air guide device.

[0040] The adjustable fan 55 is opened, air is sucked from the air inlet pipe 11, the air inlet pipe 11 guides air to enter smoothly, reduces air inlet resistance and turbulence, and reduces air inlet noise, air is sucked into the end of the mute filter plate 12 of the adjustable fan 55, and is subjected to noise reduction processing again before entering the fan, the fan blows air to the air guide heat dissipation assembly 5, the air guide plate 52 changes the air flow direction, so that air covers the heat dissipation fins 51 more uniformly, and the heat dissipation effect is enhanced, meanwhile, the air guide pipe 54 on the other side of the protection box 3 cooperates with the adjustable fan 55, adjusts the air volume according to actual heat dissipation requirements, ensures that the air-cooled water chiller body 1 is stably operated and the energy utilization efficiency is improved while the heat dissipation is efficient, and the additional noise caused by excessive or uneven air volume is reduced.

[0041] During the operation of the unit, the noise sensor 61 monitors the noise generated by the operation of the air-cooled chiller body 1 in real time. Once the noise sensor 61 captures the noise change, it will transmit the signal to the controller 64 through the wire. After receiving the signal, the controller 64 precisely controls the noise reduction degree of the first adjustable muffler 62 and the second adjustable muffler 63, and the rotating speed of the adjustable fan 55.

[0042] The sound-absorbing cotton 7 and the sound-absorbing plate 8 outside the protection box 3 play a role. The porous structure of the sound-absorbing cotton 7 absorbs noise and converts it into heat energy to be consumed. The sound-absorbing plate 8 further blocks the noise from spreading outward, thereby performing secondary isolation and absorption on the noise generated by the air-cooled chiller body 1 from the outside of the protection box 3, reducing noise leakage. The shock-absorbing plate 9 at the bottom of the supporting block 4 and the rubber plate 10 work cooperatively. The shock-absorbing plate 9 first reduces the vibration generated by the operation of the air-cooled chiller body 1 from being conducted to the ground. The rubber plate 10 is soft and elastic, further buffers and absorbs vibration energy, and reduces the structural noise caused by vibration. The mute filter screen 13 inside the air guide pipe 54 filters dust during air flow, avoids dust accumulation affecting heat dissipation and generating additional noise. The sound-absorbing ring 14 on the surface of the air guide pipe 54 absorbs and attenuates the noise generated by the airflow in the air guide pipe 54, and performs double processing of purification and noise reduction on the air passing through the air guide pipe 54.

[0043] In summary, the air-cooled chiller unit self-adaptive noise reduction and flow guiding device solves the problem that the existing air-cooled chiller unit generates noise during use and cannot adjust and eliminate the noise according to the noise condition, which leads to large noise during use of the air-cooled chiller unit, affects the surrounding environment, causes inconvenience during use, and reduces the use effect of the air-cooled chiller unit.

[0044] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
