ABSTRACT:
A core is retained within a housing, and a cooling fluid is supplied axially along an axis of the core between the housing and the core in order to cool the core. The core may have core laminations provided with cooling fins, and the core laminations may be rotated with respect to adjacent core laminations so that the cooling fins provide a cascaded cooling passage for the flow of the cooling fluid. A containment/growth sleeve may be inserted within, or around, the housing having a thermal growth rate which is intermediate the thermal growth rate of the housing and the thermal growth rate of the core in order to minimize deflection of the housing with respect to the core. Fluid conduits are provided in the housing which cooperate with the cascaded cooling passages.
