A passive thermal system for use in satellites includes a solid radiator panel with a plurality of longitudinal heat pipes attached to a surface thereof. In order to add strength to the radiator panel and resist bending, in addition to their heat transporting capability, the heat pipes have an extension from their top that increases a component of an area moment-of-inertia along an axis that is orthogonal to a plane of the radiator panel. Thus, the radiator panels can be thinner than otherwise would be possible, which results in weight and cost savings. .
La présente invention concerne un système thermique passif destiné à être utilisé dans des satellites comportant un panneau de radiateur solide avec une pluralité de caloducs fixés à une surface de celui-ci. Outre leur capacité de transport de chaleur, les caloducs renforcent le panneau de radiateur auquel ils sont accouplés. Selon certains modes de réalisation, les caloducs sont structurellement modifiés pour augmenter leur moment d'inertie de surface.
