Air Cooled Generator Set: Diesel engine is a generator for horizontal bar engine or parallel bar engine. One or more large fans are used to force exhaust air toward the generator body to dissipate heat. Generally, gasoline generators and small diesel generators are used:
Air-cooled generators must be installed in open cabins, which causes greater noise;
Air-cooled generator sets have a simple structure and low failure rate, good starting performance, less air required, low fan power consumption, low fuel consumption, no risk of freezing, overheating and boiling, easy maintenance;
The air cooled generator set is suitable for plateau or places where water is scarce or cold, there is no need to consider problems such as addition ofwater, boiling point, freezing, etc. Due to the limitations of thermal load and mechanical load, the power is generally relatively low. The "Deutz" air-cooled unit does better.
2. Water-cooled generator set: Diesel engines are mainly four-cylinder, six-cylinder, twelve-cylinder and other large units. Water circulates between the inside and outside of the body, and heat is generated. the inside of the body is evacuated by the water tank and the fan. Water-cooled generator sets are mostly large-scale generator sets:
Water-cooled generator sets have complex structures, are relatively difficult to manufacture, and have many environmental requirements when used. used on chainrings, in terms of power reduction and coolant. water must be taken into account. To lower the boiling pointn, the boiling point and freezing point should be improved by adding a certain proportion of additives;
The cooling effect of water-cooled generator set is ideal for. motors with the same technical parameters, water cooling is small in size, light in weight and has high energy density. Heat transfer performance is relatively good;
Large-power generator sets are generally water-cooled. generators. There are many brands of water-cooled generator sets, such as Mercedes-Benz generator sets, Cummins generator sets, Perkins generator sets, Yuchai generator sets and Weichai generator sets, etc.
What is the typical power of a wind turbine?
Air-cooled diesel engines are generally low-power, and higher-power diesel engines are generally air-cooledsay by water.
Air-cooled generator: Use one or more large fans to force exhaust air toward the generator body to dissipate heat.
Water-cooled generator: water circulates between the inside and outside of the body, and the heat generated inside the body is discharged through the water tank and fan.
Both functions are to dissipate heat into the air, and there is not much difference in use.

Among all wind power generators, according to the high power of the wind power generator, the amount of electric energy generated by rotation of The wind power generator is also each is different.
For example, the most common 2MW direct drive wind power generator, when the wind power is sufficient and stable, can generate 2,000 degrees of electricity.tee every 60 minutes, and each rotation of the fan blades requires 3.5 seconds. , 60 minutes, is equal to 3,600 seconds, so the electricity generated by the generator per second is 0.56 kilowatt hours. Then, the electricity generated by the wind power generator fan for each rotation is 0.56 × 3.5 seconds, or 1.94 kilowatt hours. .
Detailed information
Principle of generator
The principle of wind power generation is to use wind energy to spin the blades of the wind turbine, then use a speed multiplier to increase the rotation speed to encourage the generator to produce electricity. According to current wind turbine technology, electricity production can start at a breeze speed of around three meters per second (the breeze level).
Due to the unstable air volume, the wind turbine produces an alternating current of 13 to 25 V, which doesit be rectified by the charger, then the battery is charged, so that the electrical energy generated by the wind turbine is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use.
