1. Diesel generator manufacturers: air cooling.
Air cooling is a fan blowing method that uses cold air to blow diesel generator sets, generator set stators and rotors to achieve heat dissipation of the equipment. After absorbing heat, the cold air becomes hot air. After the air between the stator and the rotor is initially combined, it is discharged through the air duct of the iron core and cooled by the cooler equipment. The cooled air is then sent into the generator by the fan for circulation to achieve the purpose of heat dissipation. The air cooling method is generally suitable for medium and small synchronous diesel generator sets.
2. Diesel generator manufacturers: hydrogen cooling.
Hydrogen cooling is made of hydrogen as a cooling medium. The heat dissipation performance of hydrogen is better than that of air. Most large steam turbine generator sets use hydrogen cooling.
3. Diesel generator manufacturers: water cooling.
Water cooling is achieved by using the method of double water internal cooling of the stator and rotor. The cold water of the stator water system flows through the water pipe to the water inlet ring installed on the stator seat, and then flows to each coil through the insulating pipe. After absorbing heat, it is collected through the insulating water pipe to the water outlet ring installed on the base. Through this process, the external water system is discharged for cooling. Diesel generator manufacturers point out that because the heat dissipation performance of water is higher than that of air and hydrogen, water cooling is more widely used in modern industrial construction and is adopted by many large, medium and large generator manufacturers' generator sets.
