Abstract
A rotating heat pipe is used for temperature control of electric motors and generators and other rotating heat generating assemblies to ensure their proper operation. The heat pipe is integral with the shaft, and unlike conventional devices, incorporates a solid-liquid phase change material as the heat transfer/transport material. In addition, it comprises a scraped surface heat exchange mechanism at the heat dissipation region to allow for high cooling rates as required. This scraped surface mechanism is preferentially driven by a magnetic coupling to eliminate issues related to leaks of the heat transfer material.
