Battery life is longer and you can travel long distances.
Water-cooled alternators use water instead of a fan for cooling. The main heating part of the alternator is the stator, and the main cooling parts of the water-cooled alternator are the stator and the coil windings. The front cover and rear cover of the generator are made of aluminum and have water channels. The stator and coil windings are fixed and sealed with synthetic resin, and there are aluminum enclosures between the stator and rotor to isolate them from the water channel. The water channel is connected to the water inlet pipe and the water outlet pipe, and the water inlet pipe and the water outlet pipe are respectively connected to the water system of engine cooling.
