Design, modeling and performance analysis of thermal control subsystem in a small scale satellite

The heat control subsystem of each satellite is responsible for providing the allowable temperature of the equipment of that satellite. Naturally, if this subsystem of the satellite is not designed properly, the satellite mission will not be performed properly. In the present work, small-scale satellite heat control subsystems have been designed by using Thermal desktop and Sinda softwares. This simulation is based on two cold and hot critical states and the results are compared with the available experimental data in the literature, which has about 9% difference. According to studies conducted in this research, the most suitable heat control equipment are paints, coatings, insulators and heaters. According to the analysis, the cargo subsystem experiences the temperature about -19 to 28 degrees Celsius before applying the proposed thermal scheme, which using AMJ-700-IBU paint, its temperature is in the range of -10 to 47 degrees Celsius that is within the allowable temperature range.
