The working principle of the air-cooled generator set is as follows:

when the engine 3 is started, the engine fan 3-1 rotates at a high speed, outside air is sucked into the air collecting hood A4 from the air inlet of the air inlet hood 12, the air in the air collecting hood A4 is divided into two parts, one part of the air is sucked by the engine fan 3-1 and respectively enters the air cooling channel A5 and the air cooling channel B6, and the other part of the air firstly passes through the air filter 10 and then enters the engine combustion chamber (see figure 4);

the cooling air in the air cooling channel A5 is mostly used for cooling the engine cylinder head 3-2 and the cylinder sleeve and is collected by the cooling cover 7, and a small part of the cooling air is discharged from the auxiliary air outlet 5-1 on the side wall of the air cooling channel A5 to cool the engine body at the lower side of the engine cylinder head 3-2 (see figure 6);

the cooling air in the air cooling channel B6 directly passes through the oil cooler 3-3 to take away heat generated by the oil cooler 3-3, then is converged with the cooling air discharged from the air outlet of the cooling cover 7 and enters the muffler cover 8 to cool the muffler, and finally is discharged from the air outlet B1-8 on the side wall of the rear cavity 1-2.

Meanwhile, the generator 2 is operated, the generator fan rotates at a high speed, outside air is sucked into the gas collecting hood B11 and is blown along the direction of the generator 2, and heat generated on the generator 2 is taken away (see FIGS. 6-7);

because the temperature of the air flow after cooling the generator 2 is not high, the air flow can be continuously used for cooling the engine 3, namely cooling air coming out of the front end of the generator 2 enters the front chamber 1-1 from the series flow channel 1-9, and an air outlet of the series flow channel 1-9 corresponds to the lower area of the engine 3 so as to cool an oil pan of the engine;

finally, the cooling air is sent out from an exhaust outlet A1-7 on the side wall of the front chamber 1-1 to reduce the temperature in the whole front chamber 1-1.
