Shanghai Yizhong Power Plant Engineer, based on your question, what are the common cooling methods for generators and what are their advantages and disadvantages? Analysis, Common generator cooling methods include air cooling, water cooling, and air-to-air cooling. Air cooling and water cooling can be understood literally. There are now many cooling methods for generators. These are all air-to-air cooling. Are there other common cooling methods for generators? What are their advantages and disadvantages? Any questions, please consult Shanghai Yizhong Power Plant
The main function of the generator fan is to disrupt the flow of gas inside the engine, so that the inside of the engine can exchange the heat withoutside, ensuring that the generator temperature is stable and uniform. The generator fan also has some cooling effect allowing hot air at the core of the stator winding and rotor to exchange with cooler air at both ends of the winding. Depending on the speed and power, it can be designed as a single-sided fan or a double-sided fan, which can be fixed between the motor bearing assembly position and the end of the winding, and a certain air flow it is necessary to leave space.
That is: bearing->fan->rotor winding->fan->bearing
