    摘要： A dynamoelectric machine has a hollow shaft for transferring heat from within a rotor of the machine to a finned heat remover. The finned heat remover is rotated by separate power, in close relationship with respect to the shaft. A lubricant in a porous bushing maintains a heat transfer relationship between the rotating finned heat remover and the shaft. A fluid within the hollow shaft evaporates at the hot end of the shaft which is radially inwardly of the rotor. The evaporated fluid then passes through the hollow portion of the shaft to its cooler end where it condenses, giving off heat to the finned heat remover. The condensed liquid then returns to the hot end and repeats the evaporative condensing cycle.
