1What is the function of the generator hydrogen cooler?

When the generator operates, the stator and rotor coils generate heat. This heat is absorbed by the hydrogen inside the generator. The hot hydrogen is pumped into the hydrogen cooler pipe and exchanges heat with the cold water from the generator. water pipe, releasing heat and transforming it into cold hydrogen. It is then pressed inside the generator to complete the cycle, and the hot water is pumped out and replaced with cold water. The hydrogen cooler is where they exchange heat, just like the condensation chamber of a refrigerator. As for why hydrogen? Since hydrogen absorbs heat better than air, high-power generators are cooled by hydrogen or water, while low-power generators are completely air-cooled.
