Why Do Generators Need Air Coolers?

There are often copper loss and iron loss when the generator works. With the operation of the generator, the temperature of the iron core and the coil will gradually increase. In order to prolong the service life of the generator, the aging speed of the metal hose compensator and the coil insulation should be slowed down, so that the temperature of the coil must not exceed a certain standard. Therefore, measures must be taken to take away 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 more commonly used cooling methods are air cooling, hydrogen cooling and water cooling. Although the effect of air cooling is poor, due to the simple and reliable operation of air cooling equipment, many medium and small generator sets are used.

The air cooler uses cooling water to cool the air with higher temperature from the generator before sending it to the generator. In fact, when the generator is working, the heat generated is taken away by the cooling water, and the air only acts as a medium. Install an air cooler to prolong the life of the generator and improve the working efficiency of the generator.
