Abstract:
A spacecraft for deployment in geosynchronous orbit about the Earth in substantially fixed orientation relative thereto, comprising a plurality of face panels which enclose a compartment containing electronic components mounted on the interior surfaces of at least some of said panels, said face panels including opposed north-facing and south-facing panels which undergo minimal sun-exposure and therefore provide safe interior surfaces for the electronic components mounted thereon, said face panels also including side panels which are successively rotated into periodic sun-exposure attitude during which their temperature normally rises so excessively as to damage electronic powering components mounted on the interior surfaces thereof, said side panels including opposed Earth-facing and anti-Earth-facing panels, and opposed east-facing and west-facing panels, said east-facing and said west-facing panels being provided with at least one continuous circulation system containing a heat exchange fluid, which continuous circulation system is in contact with both of said panels to absorb heat from the one of said panels undergoing sun exposure and circulate and transfer the heat to the other of said panels.
