ABSTRACT:
A device for thermal protection of a structure (22) is provided. In one embodiment the device comprises a retention layer (12) impregnated by a fluid substance that is normally in the liquid state. The fluid substance is resupplied to the retention layer via a porous membrane that is impermeable to the substance when it is in the liquid state but is permeable thereto when it is in the vapor state. The membrane is interposed between the retention layer and a supply space for the substance in its liquid state adjacent the structure to be protected.
