Abstract
Systems and methods for integrating a heat exchanger in an electric motor (EM) system that includes a stator and a rotor are presented. An oscillating heat pipe (OHP) is provided within a housing of the EM system. The OHP includes channel segments with a sealed working fluid. According to another aspect, channel segments formed within a core of the stator communicate with the channel segments of the housing to provide an OHP. According to another aspect, the core of the stator includes an OHP. According to another aspect, the housing includes protruding structures with embedded channel segments. According to one aspect, the protruding structures include a plurality of fins. According to yet another aspect, the protruding structures are in contact with a fluid coolant that flows in a cavity of a structure coupled to the housing.
