Abstract

An electric generator, in particular a power station generator is provided, having at least one inlet and an outlet for at least one hollow conduit for receiving a coolant fluid. The hollow conduit is situated in or on a rotor and/or a stator/stator bars and/or a shaft and/or a housing of the electric generator wherein the hollow conduit is set up as an evaporator for receiving thermal energy from the electric generator via the coolant fluid. The cooling process allows the efficiency of the electric generator to be increased.
