[0023] Working principle: Based on the relationship between gas velocity and pressure in Bernoulli's principle, the top of the shell 2 is designed to be a continuous arc-shaped protrusion, while the bottom of the shell 2 is a plane. When wind blows through the shell 2, the airflow is accelerated by the arc-shaped protrusion and its pressure is reduced, while the airflow flowing through the bottom of the device is not accelerated and the pressure is relatively high. A first guide plate 7 is installed on the bottom of the shell 2. When the first guide plate 7 is opened, the opening direction is opposite to the airflow direction, so that the airflow enters the interior of the device due to inertia and generates a certain compression, so that the internal air pressure of the device is higher than the air pressure at the top of the device. A second guide plate 12 is installed on the top of the device. When the second guide plate 12 is opened, the opening direction is the same as the airflow direction, so that the airflow flows smoothly through the top of the device. At this time, due to the pressure difference between the inside and outside, the air inside the device is drawn out from the airflow outlet 11, and is continuously replenished from the airflow inlet 6 at the bottom, thereby forming a cycle to dissipate heat for the generator set inside the device. The working intensity of the generator set changes with the change of wind force, so the generation of the circulating heat dissipation airflow can be synchronized with the working condition of the generator set. At the same time, a cooling fan 4 is installed at the end of the generator set. When the natural wind cannot meet the heat dissipation demand of the generator set, the cooling fan 4 is started for auxiliary heat dissipation;

[0024] When the generator set has an abnormality and needs to be shut down for maintenance, the photovoltaic panel 22 is first deployed through the third steering gear 18, so that the cooling fan 4 can continue to be powered to reduce the cabin temperature during shutdown, thereby improving the working environment for maintenance personnel;

[0025] When winter comes, the first servo 9 and the second servo 15 can be used to drive the rocker arm to deflect, so that the rocker arm pulls or pushes the first guide plate 7 and the second guide plate 12 through the connecting rod, so as to control the opening and closing degree of the guide plate, or completely close it to prevent the temperature in the cabin from being too low and causing malfunctions.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
