Aircraft component with a surface exposed to an ambient air-flow and a heat transfer device and a method for operating a heat transfer device with a aircraft component

A method for operating heat exchange apparatuses in conjunction with an aircraft component with at least one heat exchange apparatus comprising:

• providing:
• an aircraft component, having a face over or around which ambient air flows, and
• a heat exchange apparatus including at least one heat exchange face
• wherein the at least one heat exchange face is arranged to face externally, to be in contact with the ambient air;
• wherein the face of the aircraft component is positioned adjacent to and/or at least partly surrounds the at least one heat exchange face;
• wherein the heat exchange apparatus includes a thermal insulation layer positioned on a side of the heat exchange apparatus facing internally away from the ambient air;
• wherein the heat exchange apparatus is thermally coupled to an additional heat exchange apparatus that is arranged at the side of the heat exchange apparatus facing internally, away from the ambient air;
• a control apparatus configured for adjusting heat exchange between the heat exchange apparatus and the additional heat exchange apparatus;
• using the control apparatus to control the heat exchange in accordance with an operating parameter of the aircraft.

An aircraft component, having a face over or around which ambient air flows, and

• a heat exchange apparatus including at least one heat exchange face,
• wherein the at least one heat exchange face is arranged to face externally, to be in contact with the ambient air;
• wherein the face of the aircraft component is positioned adjacent to and/or at least partly surrounds the at least one heat exchange face;
• wherein the at least one heat exchange face is thermally coupled to a secondary circuit of a second fluid which is thermally coupled to a primary circuit with a first fluid via a second heat exchange apparatus.
