| 发明名称 | Radial vent composite heat pipe | ||
| 摘要 | 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. | ||

| 主权项 | 1. A radial vent composite heat pipe system for cooling and increasing the power density of an electrical machine, said system comprising a plurality of radial vent composite heat pipe assemblies, wherein each heat pipe assembly comprises: a slot portion disposable within a respective one of a plurality of stator slots of a stator core pack of a stator assembly of an electrical machine; and a vent portion thermally connected to the slot portion and disposable within a respective one of a plurality of stator vents of the stator assembly, wherein: the slot portion of each heat pipe assembly is structured and operable to absorb heat from a respective one of a plurality of stator coils of the stator assembly and transfer the absorbed heat to the respective vent portion, andthe vent portion of each heat pipe assembly is structured and operable to reject the transferred heat from the slot portion of the respective heat pipe assembly 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. | ||
