Rack is widely used in technical field of optical fiber communication, generally, need to install on rack to fall Hot-air fan to reduce the temperature of cabinet inner member, in order to avoid inner member is impaired due to high temperature, this will produce certain noise, along with the requirement of people to living environment is more and more higher, increasing people can not adapt to the environment having rack noise to exist.
Summary of the invention
Object of the present invention is just to provide a kind of noise-reduction cabinet to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of noise-reduction cabinet, comprise cabinet body and hood, described cabinet body is provided with falls Hot-air fan, the described blowing mouth falling Hot-air fan is towards described interior of equipment cabinet, described hood comprises interior cover body and outer outlet body, described cabinet body is arranged in described interior cover body, gap between described cabinet body and described interior cover body cover mouth place is provided with sealing strip, multilayer silencing cotton is provided with between described interior cover body and described outer outlet body, the described air-vent falling Hot-air fan is provided with blower cover, the air-vent of described blower cover is connected with the induced duct of domes, the air-vent of described induced duct extends to described outer outlet body outside.
Further, described interior cover body and described outer outlet body are the rectangular structure of an opening.
Further, described cabinet body is arranged in described interior cover body by fixed leg.
Further, described fixed leg is hollow structure, and inside is filled with sound-absorbing material.
Further, described sealing strip is made up of sound-absorbing material, and is distributed in the surrounding of described cabinet body.
Further, silencing cotton described in multilayer is all fixed between described interior cover body and described outer outlet body by deck.
Further, described blower cover is horn structure, the air-vent place of Hot-air fan falls described in the big opening end of described blower cover covers on, the osculum end of described blower cover docks with the air outlet of described induced duct, and the air-vent of described induced duct is communicated with extraneous air with described outer outlet body through silencing cotton described in described interior cover body, multilayer successively.
Beneficial effect of the present invention is:
The present invention is provided with the hood with multilayer silencing cotton outside cabinet body, most of noise can be absorbed, by the arch airduct designed for cabinet fan, effectively can weaken the noise that fan brings, therefore this structure effectively can eliminate the noise that rack brings, and greatly reduces the noise pollution degree to surrounding enviroment.
Accompanying drawing explanation
