AI Technical Summary

Technical Problem

Existing cabinets produce a lot of noise pollution during the heat dissipation process, and traditional cabinets lack effective noise reduction measures, resulting in significant noise overflow.

Method used

A double-layer noise reduction cabinet is designed. By setting a hinge connection between the main cabinet body and the rear door air duct box, the bottom and rear door air duct box are embedded, and partitions and sound silence cotton are installed to form a snake-shaped air duct structure, and the sound silence cotton is used to perform secondary sound absorption and noise reduction.

Benefits of technology

It effectively reduces noise pollution during cabinet heat dissipation, and by extending the sound overflow distance and using sound silence cotton to perform secondary sound absorption, it significantly reduces the final discharged noise level, solving the noise problem of traditional cabinets.

Abstract

The utility model relates to the technical field, and discloses a noise reduction double-layer cabinet, which comprises a main cabinet body and a rear door air duct box, hinges are arranged at the back end and the front end of the main cabinet body, the main cabinet body is hinged with the rear door air duct box through the hinges, a cabinet door is hinged at the front end of the main cabinet body through the hinges, and a bottom air duct box is embedded at the inner bottom end of the main cabinet body. According to the utility model, bottom air is sucked into the top air duct box through the fan by using the bottom air duct box and the rear door air duct box, enters the rear door air duct box through the opening and the air inlet, and forms an S-shaped air duct effect through the sound insulation cotton which is arranged at intervals in a staggered manner, so that the sound is prevented from overflowing out of the cabinet body; meanwhile, secondary sound absorption and noise reduction are carried out by utilizing the silencing cotton in the sound discharge process, so that the sound finally discharged out of the cabinet body is reduced to the minimum, the problem of noise pollution generated during heat dissipation in the prior art is solved, and the penetration rate of server noise is reduced to a great extent by only arranging one air outlet in the rear end of the cabinet body.
