In order to minimize the quality of the thermal management system, while keeping the electronic equipment in safe working conditions, this paper proposes a research on the thermal environment and passive thermal control (PTC) systems of nanosatellites based on a computational fluid dynamic CFD tool. The idea of this work is to provide PTC for nanosatellites at a specific altitude in low Earth orbit in order to determine their temperature value. According to the results obtained, when heat dissipation was specified for the batteries, the heat distribution across the nanosatellite was heterogeneous with some temperature spikes intolerable by the structure boundaries. It was also noticed that the temperature tilted by the choice of surface coating which was specified by the α/ε ratio.
