Box 1 plays seal box guard action, generally adopts steel sheet and channel-section steel fixed connection to form, and cavity 11 and last cavity under its inside being provided with, cavity 11 is used for holding the oil tank down, and calorific capacity is lower, for cold storehouse, certainly, also can arrange the battery in cavity 11 down, and the two occupation space is great, the volume is heavier, sets up and does benefit to space rational utilization in infrastructure in cavity 11 down, can play the effect of stabilizing the focus again. A partition plate 10 is arranged in the upper cavity, the partition plate 10 divides the upper cavity into a left cavity 12 and a right cavity 13, the left cavity 12 is mainly used for accommodating an electric control assembly, the heating value is low, and the electric control assembly is a cold bin; the cavity is mainly used for accommodating an engine and a motor, and the heat productivity is large and is a hot bin. According to the invention, through designing cold-heat separation, the gas in the hot bin is prevented from entering the cold bin and damaging devices in the cold bin, so that the left cavity 12 and the lower cavity 11 are respectively in an isolated state with the right cavity 13 under a general condition, but the isolated design is not beneficial to heat dissipation and wiring of the devices in the cold bin, therefore, in the next embodiment of the invention, a design scheme for communicating the left cavity and the right cavity with each other is provided, and when the communication of the left cavity and the right cavity is considered, the prevention of the gas in the hot bin entering the cold bin and damaging the devices in the cold bin must be considered.

In an embodiment of the present invention, the lower cavity 11 and the left cavity 12 are respectively isolated from the right cavity 13, the air-cooled engine 2 is adopted to suck cold air to dissipate heat of the engine, and in consideration of the fact that the cold air can cool devices in a cold bin before being sucked into the engine, the embodiment further includes an exhaust hood 3, the left cavity 12 is provided with an air inlet 14, the right cavity 13 is provided with an air outlet 15, the partition 10 is provided with at least two ventilation openings 16, the left cavity 12 is used for accommodating an electronic control component, the air-cooled engine 2 is arranged in the right cavity 13 and is provided with a cylinder air inlet 21, an air-cooled air inlet 22, a tail gas exhaust outlet 23 and an air-cooled air outlet 24, the cylinder air inlet 21 and the air-cooled air inlet 22 are respectively communicated with the ventilation openings 16, the tail gas exhaust outlet 23 and the air-cooled air. Therefore, cold air is sucked from the air inlet 14 to cool the electric control assembly in the left cavity 12, and then a part of the cold air enters the air-cooled engine 2 to cool an engine cylinder and is discharged through the air outlet 15; and the other part of cold air enters the air-cooled engine 2, is mixed with fuel oil for combustion, drives the engine to do work, and discharges the generated tail gas through the air outlet 15. Specifically, as shown in fig. 3 to 5, the air-cooled engine 2 includes a cylinder 25, a casing 26, a turbofan 27 and a motor 28, the casing 26 covers part of the surface of the cylinder 25 and forms an air duct therebetween, the casing 26 is provided with an air-cooled air inlet 22 and an air-cooled air outlet 24, the cylinder 25 is provided with a cylinder air inlet 21 and a tail gas exhaust port 23, the turbofan 27 is disposed in the casing 26 and rotatably connected with the casing 26 and is disposed right opposite to the air-cooled air inlet 22, and the surface of the turbofan 27 is provided with a ring of gear teeth and is in transmission connection with the motor 28. Therefore, cold air enters the casing 26 through the air-cooled air inlet 22, is discharged through the air-cooled air outlet 24 after performing heat exchange on the surface of the cylinder 25, and in the process, the motor 28 drives the turbine fan 27 to rotate to play a role in air suction.

Considering that the temperature of the tail gas is high and the temperature of the cooling air of the engine cylinder is low, if the tail gas and the cooling air are directly mixed in the exhaust hood 3, the cold energy is lost, further considering that the heating temperature of the silencer 4 by the tail gas can be increased, and the cooling air of the engine cylinder can be used for cooling the silencer. Therefore, in a preferred embodiment, the air-cooled engine 2 further includes an exhaust hose 29, the silencer 4 is disposed at the air outlet 15 and fixed to the box 1, and the exhaust hose 29 is disposed in the exhaust hood 3 and has two ends respectively communicating with the exhaust outlet 23 and the silencer 4.

In another embodiment of the present invention, the lower cavity 11 and the left cavity 12 are respectively communicated with the right cavity 13, and in order to prevent the gas in the hot bin from flowing back into the cold bin, a suction fan is required to be arranged in the right cavity 13, to suck cold air from the lower cavity 11 and the left cavity 12, to cool the devices in the cold bin, and then to cool the enclosure 26, and finally to cool the muffler 4. However, if the air-cooled engine 2 is still in operation once the suction fan fails, the air in the hot compartment will be back-filled into the cold compartment. In order to prevent the above problems, the air-cooled engine 2 and the suction fan need to be designed in a linkage manner, specifically, the air-cooled engine 2 is in transmission connection with a generator rotor and axial flow fan blades, the collecting cover 6 covers the outer sides of the generator and the axial flow fan blades and is respectively communicated with the right cavity 13 and the collecting cover 6, the lower cavity 11 is communicated with the right cavity 13, and the lower cavity 11 is provided with an air inlet 14.

In particular, the generator, the axial fan blades and the collecting cover 6 can adopt the prior art.

The battery sets up in cavity 11 down, is close to air intake 14 and sets up, is convenient for cool down nearby to with generator and automatically controlled subassembly electric connection.

Specifically, the air outlet 15 is arranged at the top of the box body 1. In the existing design, the air outlet 15 is arranged on the side surface of the box body 1, the tail gas is influenced by external air flow and can pollute the box body 1, and the problem can be prevented by arranging the air outlet on the top of the box body 1.

Specifically, still include grille cover 5, grille cover 5 covers and is established in gas outlet 15 department and fixed with box 1, and muffler 4 sets up in grille cover 5. The grille cover 5 can play a role in ventilation.
