发明名称 Motor rotor cooling with rotation heat pipes
摘要 A heat pipe is partially-filled with a liquid, such as water, and is used to transfer heat from a rotating element, such as a rotor, via phase change and internal recycle of the liquid. Several heat pipes may be disposed radially around the rotating axis of the rotating element. The heat pipes may have a curved inner surface with a curvature not corresponding to the central axis of the heat pipe and positioned opposite the rotating axis so to experience greater centrifugal forces, to advance formation of a liquid film to improve heat transfer. For a rotor, the heat pipes, though individually placed as revolving heat pipes, in total exhibit behavior that approximates the favorable heat-transfer behavior of a single larger rotating heat pipe, but with heat-transfer surface area dispersed throughout the rotor, and without compromising structural integrity of the rotor shaft.
