Abstract
The utility model discloses a communicational outdoor equipment cabinet fan noise-reduction device, which comprises a shell, an air outlet and a noise-reduction air duct. The air outlet is arranged on the shell. The noise-reduction air duct is disposed inside the shell. The noise-reduction air duct contains a mounting flange, an interior lining panel and a damping material. Through the design of a special air duct, an air flow structure of the air outlet is optimized; and the damping material is installed inside the device to absorb sound waves so as to achieve the purpose of noise reduction. In the meantime, by a stealth design, the whole body is arranged below an overhead guard of the outdoor equipment cabinet. Thus, the device provided by the utility model doesn't occupy unnecessary space, and the equipment cabinet has the same appearance with a common outdoor equipment cabinet.
Description
Technical field
The utility model relates to
OnePlant communication and use the Cabinet apparatus for reducing fan noise, the noise that during for reducing fan work external environment condition is produced belongs to the communication network device technical field.
Background technology
Present traditional fan heat radiating type Cabinet, the noise that produces during fan work is at the 50-60 decibel, and the noise permissible criterion of outdoor residential block is the 35-45 decibel, long-term noise pollution causes peripheral trade company, resident to complain, and has restricted the scope of application of rack.
Summary of the invention
At the deficiency of traditional product, the utility model provides a kind of device that produces noise when reducing fan work, and it has optimized exhaust outlet gas communication structure, absorbs the purpose that sound wave reaches noise reduction by sound-absorbing material.
The technical problem that solves: traditional air outlet structure is fairly simple, does not have the air channel of design specialized, can not effectively reduce wind when causing the air draft of rack internal fan and make an uproar.
The technical scheme that the utility model adopts is: a kind of Cabinet apparatus for reducing fan noise is characterized in that: it comprises shell, air outlet, noise reduction air channel, and described air outlet is arranged on the described shell, and described noise reduction air channel is arranged at enclosure.
Above-mentioned Cabinet apparatus for reducing fan noise, it is further characterized in that: described noise reduction air channel comprises mounting flange, interior lining panel, sound-absorbing material.
Above-mentioned Cabinet apparatus for reducing fan noise, it is further characterized in that: adopt stealthy design, be installed on the Cabinet top, be hidden in rack overhead guard bottom, air outlet links to each other with the noise reduction air channel, and until fan, air outlet extends to rack overhead guard outward flange.
The beneficial effect of the utility model embodiment is: the noise of discharging when effectively reducing fan work, through test, standing in and recording level of noise apart from 1.5 meters of rack is the 38-40 decibel.
Description of drawings
Fig. 1 is for installing Cabinet cross section view of the present utility model.
Fig. 2 is structure explosive view of the present utility model.
Among Fig. 1: 1-1, Cabinet overhead guard; 1-2, the utility model; 1-3, induced draft fan.
Among Fig. 2: 2-1, shell; 2-2, air outlet; 2-3, sound-absorbing material; 2-4, interior lining panel; 2-5, mounting flange.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
The technical scheme that the utility model embodiment adopts is: as shown in Figure 2, it comprises shell 2-1, air outlet 2-2, noise reduction air channel, described air outlet 2-2 is arranged on the described shell 2-1, described noise reduction air channel is arranged at described shell 2-1 inside, described noise reduction air channel comprises mounting flange 2-5, interior lining panel 2-4, sound-absorbing material 2-3, installs successively.Its characteristics are: 1, design specialized air channel, and over against fan, make noise that fan sends with hot blast, discharge rack by the air channel; 2, in the air channel, sound-absorbing material is set, make sound wave can go deep into material internal along these holes, with material generation rubbing action acoustic energy is converted into heat energy.Thereby effectively reduce noise; 3, stealthy design, denoising device are wholy set in Cabinet overhead guard 1-1 bottom, the occupying volume external space not, and outward appearance is consistent with common outdoor cabinet.Air outlet 2-2 links to each other with the noise reduction air channel, and until induced draft fan 1-3, air outlet 2-2 extends to Cabinet overhead guard 1-1 outward flange.Fig. 1 is for installing Cabinet cross section view of the present utility model.
Though the utility model is described by embodiment, embodiment and accompanying drawing are not to limit the present invention.Those skilled in the art can make various distortion and improvement in the scope of spirit of the present invention, but equally within the protection range of invention.What therefore protection scope of the present invention should be defined with the application's claim protection range is as the criterion.
Claims (4)
1. communication Cabinet apparatus for reducing fan noise, it is characterized in that: it comprises shell, air outlet, noise reduction air channel, and described air outlet is arranged on the described shell, and described noise reduction air channel is arranged at described enclosure.
2. communication according to claim 1 Cabinet apparatus for reducing fan noise is characterized in that: described noise reduction air channel comprises mounting flange, interior lining panel, the sound-absorbing material of installing successively.
