Square cabin, manufacturing method of square cabin and generator set using square cabin

Abstract

The invention relates to the field of power supply, in particular to a square cabin, a manufacturing method of the square cabin and a generator set using the square cabin. The square cabin is enclosed jointly by a base, a top plate, side plates and a frame, wherein porous metal plates are arranged inside the side plates. The insides of the side plates which form a device cabin are connected with bypass wind tunnels. At least one turn is arranged between an air inlet and an air outlet of each bypass wind tunnel. Exhaust ports are arranged on the side plates which form an air-out cabin. The manufacturing method of the square cabin comprises the steps of: manufacturing the frame; pressing the side plates and the porous metal plates together; embedding the top plate and the side plates into the frame and arranging the bypass wind tunnels and the exhaust ports; manufacturing the base; and connecting the frame and the base into a whole. The generator set comprises the square cabin and an engine and generators in the square cabin. The porous metal plates are arranged inside the side plates so as to absorb noise in the square cabin effectively. The bypass wind tunnels are arranged to absorb part of sound waves in the condition of meeting the requirements of ventilation and heat rejection, thereby further reducing the noise.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a shelter, a manufacturing method of the shelter and a generator set using the shelter. Background technique [0002] With the development of society, electricity has become an indispensable energy source in people's daily life. The general power source is to obtain power by connecting the load to the grid, but in some cases, such as the grid is damaged or cannot be connected to the grid in the wild, at this time, in order to maintain the normal operation of the load, a generator set is required. [0003] Existing generator sets are very noisy when they are in use, which will cause serious noise pollution. Therefore, they are generally placed in a closed anechoic environment for sound insulation and noise reduction, but in this way, the heat generated during the working process of the generator set will be reduced. It will be stored in a closed and anechoic environment, which will re...

The general power source is to obtain power by connecting the load to the grid, but in some cases, such as the grid is damaged or cannot be connected to the grid in the wild, in order to maintain the normal operation of the load, a generator set is required

[0003] Existing generator sets are very noisy when they are in use, which will cause serious noise pollution. Therefore, they are generally placed in a closed anechoic environment for sound insulation and noise reduction, but in this way, the heat generated during the working process of the generator set will be reduced. It will be stored in a closed and anechoic environment, which will reduce the working efficiency of the generator set and cause serious safety hazards
