A Cryogenic Heat-Pipe Radiator for Heat Rejection from Titan Surface Electronics

This study sizes the Titan surface system named in its title for operation in the Titan surface environment, and reports the result as SIMULATED, NOT MEASURED. The design is developed from stated physical relations and a shared environmental basis, and every performance figure is computed by the deposited script rather than asserted. Among the computed results are radiator area of 5.73 square metres, radiative heat flux from the panel of 349.0 watts per square metre, heat pipes required of 17 pipes. Mass and power budgets are assembled from components so that they can be audited, off-design behaviour and materials uncertainty are discussed openly, and the limits of the sizing are stated in full. The radiator is a civilian thermal-control component for science instruments and habitat electronics; it moves heat from equipment to the sky and has no application beyond cooling peaceful surface plant.
