SPACE VEHICLE Russian patent published in 2012 - IPC B64G1/10 B64G1/50 

FIELD: transport.

SUBSTANCE: invention relates to space engineering and concerns design of automatic space vehicles (SV) for operation on low earth orbits with instrument containers made of honeycomb panels using heat pipes (HP). Space vehicle contains multipurpose payload, unsealed instrument container of parallelepipedic (prismatic) form with built-in heat pipes in honeycomb panel with heat-loaded instruments installed. Container faces are radiator. In unsealed instrument container, instrument modules with x-shaped power honeycomb panels and baffle boards. X-shaped honeycomb panels are interconnected by heat pipes. All honeycomb panels of instrument container are connected in single heating system by heat pipes equipped in the area of each honeycomb panel with electric heaters having control temperature transmitter units. X-shaped honeycomb panels and power plant brackets are connected by heat pipes with collector heat pipes of instrument container. On external surfaces of honeycomb panels containing built-in heat pipes, temperature-regulating covering is applied, the rest part of external surfaces of honeycomb panels is thermally insulated. Instrument container is equipped with additional regulated radiative heat exchanges with contour heat pipes the evaporators of which are connected with collector heat pipes of instrument container via honeycomb panels with built-in heat pipes. Condensers of contour heat pipes are positioned over thermally insulated parts of honeycomb panels of instrument container.

EFFECT: improved thermostabilisation of instruments and equipment while providing uniform field of temperatures within each honeycomb panel and between honeycomb panels of instrument container with simultaneous increase in density of instrument container packing.
