Abstract
A system for liquidly cooling rotor coils whose end turns are embedded in the rotor. A distribution chamber and a discharge chamber are arranged on opposite axial ends of the rotor and constitute supply and return manifolds, respectively. The distribution and discharge chambers are fluidly connected to coolant conduits which promote heat transfer to coolant flowing therein from electrical coils disposed in slots formed on the surface of the rotor. The fluid connections include conduits with at least a portion thereof being disposed in longitudinal slots of the rotor. Each of the coolant conduits has at least one 90.degree. bend therein for alleviating conduit stresses imposed by thermal expansion of such conduits. Insulators for the conduits electrically isolate the distribution and discharge chambers from the rotor's electrical coils. Coolant conduits supplying coolant to and receiving coolant from electrical coils near each pole may be disposed in the slots radially inside or outside the coils. For coolant conduits disposed radially outside the coils, rigid channel members are utilized to prevent conduit deformation during rotor rotation.
