An apparatus for removing heat from a thermally highly loaded structure, such as a spacecraft or hypersonic aircraft, is based on an endothermic reaction, and particularly the water gas synthesis reaction. A system of pipes (2) is arranged in the areas of the structure that are to be cooled. The pipes (2) are filled with a carbon core that includes passages through which steam passes, to react with the carbon and generate water gas. The system preferably includes a steam generator that uses some of the heat from the areas to be cooled for generating the steam that is conveyed through the carbon filled pipes (2).
