摘要： 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 DEG 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.

摘要： PURPOSE:To facilitate the connecting operation for a rotor winding, by bending the end portion of the hollow conductor of the upper coil and the end portion of the hollow conductor of the lower coil such that both ends i.e. the soldering portions are horizontal, and soldering a hollow clip to connect them. CONSTITUTION:In a water-cooled rotor winding for a vertical shaft rotary electric machine, uninsulated hollow conductors 1b at the end portions of the upper coil 1 and the lower coil 1a are bent to have horizontal end planes so that the soldering portion of a hollow clip 7 is made horizontal, whereupon low temperature soldering is carried out. Thus, since the soldering portion of the clip 7 is horizontal, the soldering is facilitated, and, when they are to be disassembled after factory test for transportation, the hollow conductors 1b are made long and they are crushed at A-A lines upon disassembling to cut away the clip 7, then at a job site the crushed portions are cut away and soldered together using a new clip 7a so that hydrogen- brittleness can be avoided.
