Abstract
The invention provides an amplifier device which comprises a housing, a plurality of amplifier sets, a plurality of covers and a plurality of boxes; wherein the plurality of amplifier sets, the plurality of covers and the plurality of boxes are arranged in the housing. Outer air is introduced into the housing and diverted so that hot air is conveyed in a manner that the housing clings to the peripheral surfaces of the amplifier sets, thereby improving heat radiation effect and performing a function of discharging hot air or heat radiation. A diversion path is provided with many bending points so that rainwater which enters from the lower part of the housing cannot further contact with the amplifier sets through the bending points, thereby preventing adverse effects. The covers are pivoted with the housing and can be accommodated in an open space below the housing, thereby realizing an effect of convenient accommodation. Each box is internally provided with a take-up reel for directly arranging wires. When the box is combined with the housing and is suspended in the air, effects of facilitating wiring operation and saving manpower and time can be realized.
