Abstract:
1. A superconductive electric generating device, comprising: a rotor adapted to rotate about an axis of rotation; a superconductive winding having a plurality of conductors arranged in a winding support; a refrigeration unit having a refrigeration head fixedly arranged outside the rotor and thermally coupled to the superconductive winding; a central cavity operatively associated with the winding support extending in the direction of the axis and is connected to a lateral cavity leading laterally out of a winding support area; a cold surface thermally connected to the refrigeration head and to a condenser to condense a first and a second coolant in separate condenser chambers, the first and second coolants having differing condensation temperatures; and a first fixed thermal tube adapted to transfer the first coolant and a second fixed thermal tube adapted to transfer the second coolant, the first and second tubes extending from the condenser into a rotating lateral cavity and into an area within which the following occurs: the second fixed thermal tube is sized and configured as a cooling finger that is closed at an end located toward the central cavity and filled with the second coolant via the thermosyphon effect that is condensed in the condenser chamber of the second fixed thermal tube and is warmed by evaporation near the central cavity and passes back to the condenser chamber.
