THERMALLY MANAGEABLE SYSTEM AND ELECTRIC DEVICE

An assembly is provided that includes a thermally manageable system. The system includes a first segment, a second segment, and a third segment. The first segment has one or both of an outward facing surface that defines a plurality of channels, and an inward facing surface that defines a plurality of apertures, extending axially along the first segment. The plurality of channels (or apertures) defines at least a portion of a flow path. The third segment has a fluid ingress and an egress, each connected to respective ones of the plurality of channels or the plurality of apertures. The first, second, and third segments are capable of being secured to form a rotatable shaft that is subjectable to a thermal load, and the flow path is configured to direct a flow of fluid to manage or control the thermal load to which the rotatable shaft is subject.
