Abstract
The present invention relates to heat exchangers, and more particularly to a heat exchange apparatus configured to operate in a free air stream. In an embodiment, a heat exchange apparatus configured to operate in a free air stream includes a heat exchange structure having a shape configured to conform to a body of a vehicle when in a stowed condition; and a deployment mechanism for moving the heat exchange structure to a deployed condition external to the vehicle. The heat exchange structure has a curved surface that is concave into the air stream when the heat exchange structure is in the deployed condition.
Claims6
A heat exchange apparatus in combination with an aircraft and configured to operate in a free air stream, comprising:
- an aircraft vehicle body having a substantially cylindrical portion defining an external surface of the aircraft;
- a heat exchange structure, without a cowling, having a front surface and a rear surface opposite to the front surface, the rear surface having a shape configured to conform to a curve of the substantially cylindrical portion of the aircraft vehicle body when in a stowed condition and the front surface having a curved surface configured to face the free air stream when in a deployed condition external of the aircraft vehicle body;
- and
- a deployment mechanism for pivoting the heat exchange structure from the substantially cylindrical portion of the aircraft vehicle body to the deployed condition external of the aircraft vehicle body such that the curved front surface of the heat exchange structure facing the air stream permits air flow through the curved front surface when in the deployed condition.
