Abstract
A method for cooling an electricity generator (50) for delivering electricity to a first rotor (60), the first rotor being suitable for being rotated relative to a stationary structure, the method being characterized in that the electricity generator is placed in a chamber (62) arranged inside the first rotor, and in that it comprises the following steps: a) transferring heat produced by the generator to a cooling fluid, thereby vaporizing the fluid in an evaporator (64); b) transporting the vaporized fluid to a condenser; and c) condensing the fluid in the condenser, the heat delivered by the fluid being transmitted to the air surrounding the condenser.

A method for cooling an electricity generator for delivering electricity to a first rotor, the first rotor being suitable for being rotated relative to a stationary structure, the electricity generator being arranged in a chamber arranged inside the first rotor, wherein the method comprises the following steps:
- a) transferring heat produced by the generator to a cooling fluid, thereby vaporizing the fluid in an evaporator;
- b) transporting the vaporized fluid to a condenser;
- and
- c) condensing the fluid in the condenser, the heat delivered by the fluid being transmitted to the air surrounding the condenser.
A device comprising a stationary structure, a first rotor suitable for being rotated relative to the stationary structure, an electricity generator for delivering electricity to the first rotor, and a cooling system for discharging the heat produced by the electricity generator;
- wherein the electricity generator is arranged in a chamber arranged inside the first rotor, and the cooling system comprises a circuit for circulating a two-phase cooling fluid, the circuit connecting an evaporator that is thermally coupled to the electricity generator to a condenser that is suitable for discharging heat to the medium outside the first rotor.
