The cooling water of the generator is mainly used to cool the iron core and copper wires. Its specific function is to reduce the temperature generated by eddy currents in the motor core and the temperature generated by current in the wires, so that the motor can work normally.
The specific heat of water is important. It absorbs or releases more heat when the same temperature is raised or lowered. Using water as such has a better warm keeping effect.
