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.
