Abstract
A cooling system for the parallel rings of an electrical generator. The system includes a coolant supply tank, supply and return lines, and a plurality of parallel, tubular liquid cooled conductor rings for conducting current generated in the stator windings of an electrical generator. Each ring has a coolant inlet, a coolant outlet, a central coolant passage and an adjustable flow controller which is selectively positionable so that its end portion lies inside the temperature coolant passage in the parallel rings to restrict the coolant flow for control purposes.
