Abstract

A vehicle is provided including a structure including a skin defining an outside surface exposed to ambient cooling flow and an inside surface. The structure includes a first structural member extending from the inside surface of the skin and a second structural member extending from the inside surface of the skin; and a thermal management system including a heat exchanger assembly positioned adjacent to, and in thermal communication with, the inside surface of the skin, the heat exchanger assembly positioned at least partially between the first and second structural members of the structure.

First claim

What is claimed is:

1. A method of operating a heat exchanger assembly of a thermal management system operable with an inside surface of a skin of a vehicle, the method comprising:
inflating an inflatable member of the heat exchanger assembly operable with a cooling tube of the heat exchanger assembly to press the cooling tube towards the inside surface of the skin;
determining a condition of the vehicle, of the thermal management system, or both; and
modifying a pressure within the inflatable member in response to the determined condition of the vehicle, of the thermal management system, or both.

2. The method of claim 1 , further comprising:
positioning the heat exchanger assembly adjacent to, and in thermal communication with, the inside surface of the skin of the vehicle at a location between a first structural member and a second structural member of a structure prior to inflating the inflatable member.

3. The method of claim 2 , wherein the vehicle is an aircraft, wherein the structure is a fuselage of the aircraft, wherein the aircraft defines a longitudinal direction, wherein the first structural member is a first longitudinal stiffener extending generally along the longitudinal direction, and wherein the second structural member is a second longitudinal stiffener extending generally along the longitudinal direction.

4. The method of claim 3 , wherein the first longitudinal stiffener defines a first reference line extending away from the inside surface of the skin, wherein the second longitudinal stiffener defines a second reference line extending away from the inside surface of the skin, wherein the first and second reference lines converge towards one another, and wherein the heat exchanger assembly includes a structural backing fixed at least partially between the first and second longitudinal stiffeners for mounting the heat exchanger assembly.

5. The method of claim 2 , wherein the heat exchanger assembly is coupled to the first and second structural members of the structure.

6. The method of claim 1 , wherein the condition is an operating condition of the vehicle, of the thermal management system, or both.

7. The method of claim 1 , wherein modifying the pressure within the inflatable member comprises at least partially deflating the inflatable member.

8. The method of claim 1 , wherein modifying the pressure within the inflatable member comprises at least partially inflating the inflatable member.

9. The method of claim 1 , wherein the skin comprises an outside surface exposed to ambient cooling flow during operation of the vehicle.

10. The method of claim 1 , wherein the heat exchanger assembly is a heat exchanger assembly of a thermal management system, and wherein the thermal management system of the vehicle is thermally coupled to a heat source of an engine of the vehicle for rejecting heat from the heat source using the heat exchanger assembly.

11. The method of claim 1 , wherein inflating the inflatable member comprises providing a flow of gas to the inflatable member.

12. The method of claim 11 , wherein the inflatable member is positioned outside the cooling tube and between the cooling tube and a structural backing.

13. The method of claim 12 , wherein the structural backing mounts the cooling tube in position adjacent to, and in thermal communication with, the inside surface of the skin.

14. The method of claim 11 , wherein the heat exchanger assembly further includes a load applicator positioned between inflatable member and the cooling tube, a first standoff member, and a second standoff member, and wherein the first and second standoff members are positioned on opposing sides of the cooling tube and extend from the load applicator towards the inside surface of the skin.
