Turbine engine with integrated generator having shared lubrication system

摘要

A heat exchange system for use in operating equipment having a plurality of subsystems (11, 32) in each of which a common working fluid is utilized to provide selected operations in that subsystem with a reservoir (21) containing at least some of the common working fluid and has both a supply system and a return system connected between the reservoir and each of the plurality of subsystems through which any common working fluid in the reservoir can be conveyed. An airstream heat exchanger (12, 29) is provided connected in one of the supply and return systems so as to have the common working fluid conveyed therethrough cooled at selectively variable rates in the airstreams passing thereby during at least some such uses of the operating equipment.
