The invention discloses a mute power station shell comprising a top cap assembly, a frame, door plates, micro-hole mufflers and a filter plate. The top cap assembly is fixed at the top of the frame which is provided with wind inlets and air channels. The air channels are fixed on the door plates which are mounted on the frame. The door plates are combined with the air channels to form an accommodating chamber. The micro-hole mufflers and the filter plate are arranged in the accommodating chamber. The micro-hole mufflers are in rivet connection with the air channel. The inner surfaces of the top cap assembly, the frame, the wind channel and the door plates are all coated with viscoelastic sound insulating material. The surfaces of the walls of the frame are provided with air inlets, the air channels are arranged in the air inlets, and double-layer sound insulating walls are formed by the door plates and the air channels so as to dually eliminate noise. The micro-hole mufflers and the filter plate are arranged in the accommodating chamber to effectively reduce the noise. The viscoelastic sound insulating materials coat and mute cottons are adhered to the inner surfaces of the top cap assembly, the frame, the air channels and the door plates, thus sound wave of the noise is effectively absorbed, and the noise is further reduced.
