WIPO Patent Application WO/2015/092215
Kind Code:
A3
Abstract:
A method for cooling an electric generator (50) designed to supply a first rotor (60) with electrical power, the first rotor being capable of being brought into rotation relative to a fixed structure, the method being characterised in that the electric generator is disposed in a chamber (62) provided inside the first rotor, and in that it comprises the following steps: a) transferring heat produced by the generator to a heat transfer fluid by vaporising the fluid in an evaporator (64); b) transporting the vaporised fluid to a condenser; c) condensing the fluid in the condenser, the heat supplied by the fluid being transmitted to the air surrounding the condenser.
