<p>A heat exchange system (10) for use in operating equipment in which a working fluid is utilized in providing selected operations thereof, including for use in lubricating systems for aircraft turbofan engine equipment, the heat exchange system for providing air and working fluid heat exchanges to cool the working fluid at selectively variable rates in the operating equipment developed airstreams. A heat exchanger core (14) is provided in a controlled air flow duct system opening at its entrance to those airstreams and having its outlet end opening downstream in those airstreams. The cooling duct (11) has an exit opening (16). The entrance (12) and exit opening (16) are openable or closable by flaps (12',16').</p> |
