The water-cooling air cooling device 12 plays a role in shielding the outlet pipe 1335, so that rainwater and dust are prevented from falling above the outlet pipe 1335; and the outlet pipe 1335 has a U-shaped downward bent structure, so that the air outlet direction is bent downwards, and the noise in the power generation chamber 112 is reduced from being transmitted outwards through the outlet pipe 1335.
A first temperature sensor is provided in the engine 1121 (typically, on a water path near an engine cylinder), a second temperature sensor is provided on the engine 1121, and the first temperature sensor and the second temperature sensor are respectively connected to the controller;
the cooling method comprises the following steps:
the controller obtains first temperature data of a first temperature sensor, and when the first temperature data is larger than a first preset value (for example, 100 ℃), the controller controls the fan module to operate at a first power;
when the first temperature data is larger than a second preset value (for example, 120 ℃), and the second preset value is larger than the first preset value, the controller controls the fan module to operate at a second power, and the second power is larger than the first power;
when the fan module is operated at the second power for a first preset time (for example, 5 minutes), the first temperature data is still greater than a third preset value (for example, 180 ℃), and the third preset value is greater than a second preset value, or the second temperature data of the second temperature sensor is greater than a fourth preset value (for example, 50 ℃), the controller controls the exhaust fan to operate;
when the exhaust fan is operated for a second preset time, the second temperature data is still larger than a fifth preset value (for example, 60 ℃), the fifth preset value is larger than the fourth preset value, and the controller controls the air inlet fan on the air inlet grille to operate.
According to the cooling method provided by the embodiment, when the temperature in the engine is high, the fan module is started by the controller to operate at low power, so that the engine is cooled rapidly; when the temperature of the engine is higher, the fan module is started to operate at higher power; however, the cooling requirement is still possibly not met, and after the operation is carried out for a period of time, when the temperature is detected to be too high, the operation of the exhaust fan is continuously started, and the outside of the engine is cooled in an exhaust mode through the exhaust fan, so that the external cooling mode is simulated, and the problem of poor heat dissipation effect in the closed space is solved; on the basis, if the exhaust fan cannot ensure that the temperature is reduced to an ideal state, the air inlet fan on the air inlet grille is started, so that the outside of the engine can be actively cooled through the air inlet of the outside.
The air inlet grids are arranged on different sides of the cabin body, and the controller controls the air inlet grids on the leeward side and the air inlet fans on the leeward side to be closed according to the direction of the wind direction of the surrounding environment, and the air inlet grids on the windward side and the air inlet fans on the windward side to be opened. Thus, the air flow of the air inlet grille on the windward side is prevented from directly entering the air inlet grille on the leeward side, and more wind is blown to the engine.
The air inlet grids are arranged on different sides of the cabin body, and the controller controls the air inlet grids on the sunny side and the air inlet fans on the sunny side to be closed according to the irradiation direction of the sun, and the air inlet grids on the back-to-back side and the air inlet fans on the back-to-back side to be opened. Because the temperature of the sun facing surface is higher, the temperature of the back and yin facing surface is low, and therefore low-temperature air on the back and yin facing surface can enter the power generation chamber, and a better cooling effect is achieved on the engine.
When the fan module runs for a third preset time (for example, 10 minutes) at the second power, the first temperature data is still larger than a sixth preset value (for example, 200 ℃), the sixth preset value is larger than the third preset value, and the controller controls the engine to reduce the rotating speed or stop and sends out an alarm signal. This is an important measure to judge the failure or to avoid serious failure due to high temperature, and can avoid damage of the engine due to over high temperature.
When the air intake fan runs for a fourth preset time, the second temperature data is larger than a seventh preset value (for example, 90 ℃), the seventh preset value is larger than the fifth preset value, and the controller controls the engine to reduce the rotating speed or stop and sends out an alarm signal. This is also an important measure to judge the failure or to avoid serious failure due to high temperature, and damage to the engine due to excessive temperature can be avoided.
The generator 1121 is located between the inlet grille 131 and the inlet of the exhaust fan 132, so that after the airflow enters the power generation chamber 112, the airflow needs to pass through the generator 1121 to be sucked into the inlet of the exhaust fan 132, thereby effectively reducing the temperature of the generator 1121.

The first pipe section 1331 may be a straight pipe or a zigzag pipe formed by connecting multiple sections.
The second tube section 1333 is a flexible bellows so as to be relatively freely disposed within the electronic control chamber 111.
The heat insulation layer is coated on the outer portion of the second pipe section 1333, so that heat in the second pipe section 1333 can be prevented from entering the electric control chamber 111, and the influence on the temperature of the electric control chamber 111 due to wiring is reduced.
