1. A dynamoelectric machine including:

  • a stator having a rotor receiving opening and opposed end faces;

    slots in said stator extending between said faces;

    a plurality of electrical conductors in each of said slots and disposed therein such that interstices exist between adjacent conductors and define coolant flow paths within said slots from one end face to the other, said conductors exiting said slots at said end faces and being redirected into another one of the slots thereby defining end turns at each end face;

    two tubes on each end turn, adjacent ends of each tube being at least slightly spaced and remote ends of each tube being sealed to the associated end face about the periphery of the associated slot, said remote ends of said tubes each including a sealing flange; and

    a clamp secured to each said end face and engaging the sealing flanges of remote tube ends at the corresponding face and clamping them thereagainst in sealing relation thereto.
