when the fan rotates, the silencer under the fan can carry out the preliminary amortization of the first stage to the noise that the fan rotated and sent.
Further, the edge of the sound absorption plate is provided with a sound absorption plate;
when the noise is transmitted to the sound-absorbing plate, the sound-absorbing plate can carry out secondary noise reduction on the noise, and the sound-absorbing plate is also provided with a sound-absorbing plate at the edge and can also block part of the noise.
Furthermore, sound absorption holes are formed in the sound absorption plate and are uniformly distributed on the sound absorption plate;
the sound absorbing hole can enable noise sound waves to penetrate into the sound absorbing material along the hole to rub with the edge of the hole, sound energy is converted into heat energy, according to the law of conservation of energy, the heat energy is increased, the sound energy is reduced, and the effects of sound absorption and noise reduction are achieved.
Further, the acoustical panel is installed on the stationary housing.
Further, sound absorption cotton is bonded on the sound absorption plate;
the suction cotton may be used to absorb sound and reduce noise.
Further, a damping layer is arranged between the arched pad and the shell;
the shock-absorbing layer can reduce the vibration frequency, and the anti-seismic and noise-reducing effects are realized.
Further, the elastic part is a spring;
the spring can be used for buffering a part of vibration, and the effect of shock absorption is achieved.
Compared with the prior art, the utility model, following advantage and beneficial effect have:
1. the utility model relates to a vibration/noise reduction air cooler, to the inside acoustical panel that sets up of air cooler casing, and install and be provided with the arch pad in the bottom of casing, the pressure that the arch pad received decomposes into downward pressure and outside thrust, is the only structure that produces the external thrust in all structures, in the arch structure, because there is the effect of horizontal thrust, so make the arch pad possess outstanding performance on holistic stability; and the elastic support in the arched pad can reduce vibration amplitude properly, effectively reduce the noise generated by the rotation of the fan and overflow, achieve the silencing effect, provide the comfort level for workers, promote the working efficiency of the workers and reduce the harm of noise to human health.
2. The utility model relates to a vibration/noise reduction air cooler is provided with buffer layer and protective layer at flabellum edge part, is favorable to buffering when the flabellum rotates, and firm flabellum is because of the vibration noise that rotates the production to can avoid the terminal surface to take place the phenomenon of damage earlier because of excessive wearing and tearing, prolonged the life of protection casing body.
