Abstract
A heat exchange system for use in operating equipment in which a working fluid is utilized needing a heat exchange system to provide air and working fluid heat exchanges to cool the working fluid at selectively variable rates in airstreams. The system comprises a plurality of heat exchangers including a first heat exchanger in the plurality of heat exchangers that is mounted with respect to the equipment so as to permit corresponding portions of the airstreams to pass through the core thereof during at least some such uses of the equipment. Also, a second heat exchanger is mounted with respect to the equipment so as to selectively permit corresponding portions of the airstreams to pass through the core thereof during such uses of the equipment. A core actuator is mounted with respect to the second heat exchanger to selectively increase or reduce the passing of those corresponding portions of the airstreams through the core.
