The device for thermal monitoring for a piece of equipment, whereby said piece of equipment is integrated on a craft placed in a forced vacuum environment, an outside part (7) of the equipment projecting outside of a wall (3) of the craft and being subjected to a solar radiation flux (15), comprises an absorbent screen (13) that is suitable for being placed between the outside part (7) of the equipment and the wall (3) of the craft, whereby this absorbent screen (13) has—on at least one portion of its front face, designed to be placed on the side removed from the wall of the craft—an absorptivity αSOLAR that is the largest possible in the field of solar radiation, coupled to a low emissivity &egr;IR in the infrared spectrum. The absorbent screen (13) is made of a very heat-conductive material and has—on at least a portion of its rear face, suitable for being oriented toward the wall of the craft—a high emissivity &egr;IR in the infrared spectrum, typically greater than or equal to 0.7. |
