I I.

A rear cover 22 is attached to the rear pillar 25, and the rear cover 22 is also bolted to the left enclosure 29, the right enclosure 15 and the chassis 18. The rear cover 22 is provided with a rear cover style grille 23.

The top cover 3 is disposed at the top of the cabinet and is bolted to the tops of the front pillar 10, the rear pillar 25, the rear cover 22, the left enclosure 29, and the right enclosure 15, respectively. A top grille 2 is arranged on the left side of the top cover 3, and an exhaust port 1 is arranged in the middle of the exhaust grille 2, and an exhaust tail pipe 32 of the muffler 30 extends from the exhaust port 1 outside the cabinet.

A generator 12, an engine 5, a radiator 28, and a muffler 30 are disposed in order from the right to the left on the chassis 18 in the cabinet. The generator 12 is coaxially coupled to the engine 5. The muffler 30 is connected to the exhaust pipe 31 of the engine 5.

The engine 5 is a water-cooled multi-cylinder engine equipped with a forced circulation water cooling system, and the radiator 28 is in communication with the cooling line of the engine 5. A radiator cover 27 is fixed to the radiator 28 to protect the radiator 28. The cooling fan of the radiator 28 is mounted on the engine 5, and the outside of the fan is surrounded by a fan guard 26, and the fan guard 26 is bolted to the tank guard 26.

On the chassis 18, a left partition 33 is disposed between the radiator 28 and the muffler 30. The left partition 33 and the left enclosure 29 enclose a chamber in which the muffler 30 is disposed. The upper portion of the left partition 33 is provided with a recess for passing the exhaust pipe 31. The heat sink 28 is fixed to the left partition plate 33 by bolts.

A fuel tank 8 is disposed above the generator 12 to make full use of the space above the generator 12.

The working process of the generator set is as follows: As shown in Fig. 3, the engine 5 is forcibly cooled by a forced circulation water cooling system composed of components such as a radiator 28. The air cleaner 6 of the engine 5 draws in fresh air from the first inlet grill 13 of the bottom plate 39, and the exhaust pipe 31 exhausts the exhaust gas through the muffler 30 and the exhaust tail pipe 32. The air outside the cabinet enters the cabinet from the rear cover of the rear cover 22 into the cabinet. The guiding function of the duct plate 17 enters the cabinet from the side air inlet hole on the duct plate, and a part of the cooling air enters. The inside of the generator 12 carries heat inside the generator 12, and the other part of the cooling air is guided by the inner side of the duct plate 17 and the inner side of the panel rear cover 11, cooling the outer casing of the generator 12 and the components inside the cabinet. Thereafter, the cooling air is sucked by the suction of the fan mounted at the end of the engine 5 through the radiator 28 into the chamber in which the muffler 30 is mounted, the muffler 30 is cooled, and then discharged from the row grill 2 on the top cover 3.

The air inlet hole 14 in the bottom plate 39 of the chassis 18 and the first inlet style grid 13, the second inlet style grid 21 and the third inlet style grid 24 respectively cool some components. The air inlet hole 14 located in the middle of the bottom portion of the bottom plate 39 introduces cooling air through the floor air inlet plate 20 to cool the oil pan of the engine 5. The cooling air entering from the third inlet grille 24 on the bottom plate 39 cools the battery 4, and the cooling air entering from the second inlet grill 21 on the bottom plate 39 cools the exhaust pipe 31.

The door panel on the door panel 9 also enters the wind, and further supplements the cooling air in the cabinet.
