[0026] 2. The control cabinet is located in the control cabinet compartment, and the operation of the entire generator set is controlled by the control cabinet;

[0027] 3. Each generator cabin has two single machine units, and each single machine is provided with an electronic axial flow fan above, which can discharge the heat generated by the engine and inhale fresh air outside when in operation.

[0028] 4. Fresh air is inhaled through an air filter and mixed with low-pressure gas of the user in a mixer, the mixed gas is pressurized through a supercharger, cooled by an intermediate cooler, and enters each cylinder of the engine through a throttle valve for combustion, the engine rotates to drive the generator to generate electricity, and the exhaust gas after combustion drives the supercharger to rotate to inhale the mixed gas, and then the mixed gas passes through an exhaust pipe, an exhaust extension pipe, a collection muffler, and a user pipeline to reach a post-processing device.

[0029] 5.

When the ambient temperature is high, the first movable aluminum alloy shutter is completely closed, the second movable aluminum alloy shutter is opened, and the wind of the electronic axial flow fan is maximized to cool and cool the intermediate cooler to reduce the temperature of the mixed gas; when the ambient temperature is low, the first movable aluminum alloy shutter is opened, the second movable aluminum alloy shutter is opened or even closed, and the wind of the electronic axial flow fan is small to cool and cool the intermediate cooler to avoid a large amount of condensed water generated after the high-temperature mixed gas is rapidly cooled.

[0031] The unit adopts multiple single machines integrated into a pry, each single machine unit is placed in two engine compartments, a heat dissipation system is installed in the middle position of the box body, two engine compartments are arranged on both sides, and a control cabinet room is arranged at one end of the box body.
