Air-oil heat exchanger
First Claim
1. A heat exchange system for use in operating equipment in which a working fluid is utilized in providing selected operations thereof, the heat exchange system for providing air and working fluid heat exchanges to cool the working fluid at selectively variable rates in airstreams occurring on a stream side of a wall provided with the equipment, the system comprising:
- an actuator mounted to be substantially located on a side of the wall opposite the stream side and having a positionable motion effector therein that can be moved to selected positions with respect to an opening in the wall; and
a heat exchanger core having a plurality of passageway structures therein about which air can pass in flowing therethrough with the passageway structures being coupled to an input conduit at one end thereof and coupled to an output conduit at an opposite end thereof to enable the working fluid to be provided, and removed from, interiors of the passageway structures through interiors of the input and output conduits, the heat exchanger core being mounted on the motion effector so as to be extendable thereby through the opening for selected distances into that region to be occupied by the airstreams on the stream side of the wall, and selectively retractable from those distances.

Abstract
A heat exchange system for use in fluid operated equipment to provide air and working fluid heat exchanges to cool the working fluid in airstreams on a stream side of a wall. An actuator is mounted to be substantially located on a side of the wall opposite the stream side thereof having a positionable motion effector. A heat exchanger core having a plurality of passageway structures therein to enable providing the working fluid to, and removal therefrom. The heat exchanger core is mounted on the motion effector so as to be extendable and retractable thereby through the opening for selected distances into that region to be occupied by the airstreams.

13. A heat exchange system for use in lubricating systems for aircraft turbofan engine equipment in which a lubricant is provided under pressure to spaces bounded at least in part by surfaces moving relative to one another, the heat exchange system for providing air and lubricant heat exchanges to cool the lubricant at selectively variable rates in airstreams occurring on a stream side of an engine fan duct wall, the system comprising:
-
a controllable motor having a shaft with a selectable angular position with the motor being mounted to be substantially located on a side of the wall opposite the stream side and having a positionable motion effector coupled to the shaft that can be moved to selected positions with respect to an opening in the wall by selected rotations of the shaft; and
a heat exchanger core having a closing structure thereon and having a plurality of passageway structures therein about which air can pass in flowing therethrough with the passageway structures being coupled to an input conduit at one end thereof and coupled to an output conduit at an opposite end thereof to enable the lubricant to be provided, and removed from, interiors of the passageway structures through interiors of the input and output conduits, the heat exchanger core being mounted on the motion effector so as to be extendable thereby through the opening for selected distances into that region to be occupied by the airstreams on the stream side of the wall in an extended position, and selectively retractable from those distances including retracted sufficiently to be out of the region to be occupied by the airstreams if the heat exchanger core is in an unextended position such that the closing structure on the heat exchanger core substantially blocks the opening. - View Dependent Claims (14, 15, 16, 17)
