Noise-proof telephone booth metal shell capable of automatically adjusting temperature and manufacturing method thereof

Abstract

The invention relates to a noise-proof telephone booth metal shell capable of automatically adjusting temperature. The noise-proof telephone booth metal shell comprises an inner metal plate layer andan outer metal plate layer and also comprises a heat conduction layer, a heat conduction material layer, a phase change material layer, a sound attenuation and noise reduction layer, wherein the heatconduction layer is made of carbon fibers and has the characteristics of light weight, high strength, corrosion resistance, high temperature resistance and excellent heat conduction and electrical conductivity; the heat conduction material layer is formed by filling graphene in a metal net, and is high in overall rigidity and stable in size; the phase change material layer is made of carbon nanotubes and is high in phase change latent heat and small in phase change latent heat change. According to the noise-proof telephone booth metal shell, the phase change material layer is arranged, so thatthe temperature adjusting performance of the telephone booth shell is improved, the temperature in the telephone booth is kept comfortable in the four seasons, and the excessively hot and excessivelycold phenomena are avoided; the sound attenuation and noise reduction layer comprises an inner sound absorption plate layer with sound absorption holes, an outer sound absorption plate layer with sound absorption holes and a sound attenuation cotton layer arranged between the sound absorption plates, so that the sound attenuation and noise reduction performance of the telephone booth shell is greatly improved; a sawtooth structure is arranged, so that the structure strength is improved, the structure safety of the telephone booth is improved, and the sound absorption effect is further improved.

Description

technical field [0001] The invention belongs to the technical field of telephone booth metal shells, in particular to an automatic temperature-regulating noise-proof metal shell of a telephone booth and a manufacturing method thereof. Background technique [0002] Telephone booths are public communication facilities commonly used indoors and outdoors in public, industrial and other places. Existing telephone booths are mainly open structures in terms of appearance design, with a relatively large open area, and the effect of isolating external noise is not good. The shell of the telephone booth in the prior art mainly adopts the integral molding technology of glass fiber reinforced plastic, and relies on direct isolation and blocking means to realize the local noise reduction function, but the inner wall of the glass fiber reinforced plastic material has a large noise reflection, which will produce superposition and reverberation with the voice of the caller. It affects the ...

Existing telephone booths are mainly open structures in terms of shape design, with a large open area, and the effect of isolating noise from the outside is not good

The shell of the telephone booth in the prior art mainly adopts the integral molding technology of glass fiber reinforced plastic, and relies on direct isolation and blocking means to realize the local noise reduction function, but the inner wall of the glass fiber reinforced plastic material has a large noise reflection, which will produce superposition and reverberation with the voice of the caller. Affect the call quality and voice clarity of the caller, the noise reduction effect is relatively poor, reduce the call quality, and fail to meet the requirements of a good call
