COSMIC APPARATUS Russian patent published in 2005 - IPC

FIELD: the invention refers to means of temperature control of cosmic apparatus working on geostationary or high elliptical orbits.

SUBSTANCE: the proposed apparatus has an instrument container, located in a heat-insulation shield fulfilled in the form of a cylindrical sleeve with a cut. One butt-end of the instrument container is connected with the bottom of the sleeve with possibility of turning the shield relatively to the instrument container and a purpose sampling apparatus is installed at the other butt-end of the instrument container. A cylindrical radiator-refrigerant with thermal screen is installed axially to the instrument container through thermal outcome. The cosmic apparatus has a thermo buffer filled with heat-accumulating substance with the melting temperature on the level of the working temperature of the purpose sampling apparatus. The radiator-refrigerant is formed with several heat-insulating one from another sectors. Every part is connected with the butt-end of the element of the instrument container with low thermal conductivity and with the thermo buffet by the way of a thermo diode. The thermo duffer is connected with the purpose sampling apparatus by a thermal tube. A labyrinth seal may be fulfilled in the gap between the radiator-refrigerant and its thermal shield.

EFFECT: increases effectiveness of maintaining of the two-level temperature regime of optical systems of remote probe of the EARTH at voluntary orientations relatively to the Sun.
