During the operation of the generator, due to the existence of current and magnetic field, iron loss and copper loss will inevitably occur. This loss is transmitted to the windings and iron core as heat, which will cause heat. When we design the equipment, the temperature it withstands will be considered in the range. In order to avoid overheating and excessive cooling, we often use an air cooler to cooperate. So the air cooler plays a very good cooling effect in the whole process. The heat of the generator will not be so high, allowing it to work normally and extending its lifespan.
Copper loss and iron loss often occur when the generator is operating. As the generator operates, the temperature of the iron core and coil gradually increases. In order to extend thelife of the generator, the aging speed of the metal pipe compensator and the insulation of the coil should be slowed down, so that the temperature of the coil should not exceed a certain standard. Therefore, measures should be taken to discharge the heat generated by the coil and the iron core in time to maintain the temperature of the coil insulation not exceeding the specified value. The most commonly used cooling methods include air cooling, hydrogen cooling, and water cooling. Although the effect of air cooling is poor, the air cooling equipment is simple and reliable, so it is widely used in medium and small generator sets.
The air cooler uses cooling water to cool the higher temperature air leaving the generator, then sends it into the generator. Indeed,When the generator works, the generated heat is carried away by the cooling water, and the air only acts as a fluid. Installing an air cooler extends the life of the generator and improves its efficiency.

Is the air cooler a water tower cooling?
Water pipes are ordinary. Copper tubes are made of 20mm diameter and 2mm thickness copper tubes with good heat transfer performance. There are two water chambers on both sides of each group to feed and return water to the stator coil and the iron core of the. generator. The heat emitted from the rotor coil and iron core passes through the generator rotor shaft. The fan blows hot air to the air cooler, cools it with water, then sucks it into the cooledrotor-stator air collector. through both ends of the generator to form a circuit. However, this has nothing to do with the electrical circuit, unless a leak from the air cooler will cause a decrease in generator insulation.
Air Cooling The full name of the device . should be an air cooler, which uses air as a cooling medium. The cooling tower also cools the circulating water by air. It should be possible to say yes. But in general, power plant air cooler usually refers to generator air cooler. This is the house under the unloading machine. The cooling water tower is so big I think you should be able to see it there.
