FIELD: space technology. SUBSTANCE: solar sonde has forepart heating protector made like cone and additional thermoprotecting screen made as cut off cone attached to forepart cone by base-to-base. Reversed cone is composed by three identical sections and each of them has shield-diaphragm placed perpendicular to longitudinal axis of apparatus, side surface and L-shaped heat pipes made so that each pipe evaporating part is mounted at shield-diaphragm surface but its condensation part is placed at side surface. Forepart cone and reversed cone sections are connected mutually by thermoinsulating spacers and the last section has strength force ring with heating protection wall and instrument container made like flat heat accumulating device. Some probes of research equipment are placed at folding bars. EFFECT: better heat protection of solar sonde. 4 cl, 1 tbl, 4 dwg
