Cooling HTS Wind Generator HTS Rotor Coils

Techniques are described for a wind power generator in which a refrigerant such as liquid helium and/or helium gas is applied to superconducting magnets via thermally conductive flexible structures. These structures thermally couple the refrigerant channels to the magnets, and/or to a thermally conductive structure (e.g., metal plate) to which the magnets are thermally coupled. The thermally conductive flexible structures may be arranged so that motion of the magnets relative to the cryogenic channels that cool the structures during heating and/or cooling of the magnets does not result in damage to the thermal connection between the channels and the magnets. The stationary stage of the generator may house a cooling station, and transfer the refrigerant to the rotary stage via a suitable rotary union.
