Abstract
A radial vent composite heat pipe system for cooling and increasing the power density of an electrical machine is provided. The system comprises a plurality of radial vent composite heat pipe assemblies each comprising a slot portion thermally connected to a vent portion. The slot portions are disposable within respective stator slots of a stator core pack of a stator assembly of the electrical machine. The vent portions are disposable within stator vents of the stator assembly. The slot portions absorb heat from the stator coils of the stator assembly and transfer the absorbed heat to the vent portions. The vent portions reject the transferred heat into a cooling air flowing through the respective stator vent, thereby rapidly transferring heat from the respective stator coil to the cooling air flowing through stator vent, and thereby greatly increasing the power density of the electrical machine.
