Among them, forced air cooling is mainly used in models below 750kw. The generator is used for cooling, and as the capacity of the fan develops towards high power, the power requirement of the fan using forced air cooling will also increase accordingly, which will inevitably increase the energy consumption of the temperature control system. And the outer dimension of the blower increases with the increase of the power, and the internal space of the fan is limited.
