One of the major reasons, why nanosatellites are still in a state of vulnerability, is the increase of their thermal temperature, which in many cases leads to the failure of the missions they were originally designed for. In order to maintain the quality of the thermal management system, while keeping the electronic equipment in reliable working conditions. This paper presents a research on the thermal environment and the passive thermal control systems (PTC) of nanosatellites, based on a CFD computational fluid dynamics tool. The idea of this work is to provide a PTC to nanosatellites at a specific altitude in low earth orbit in order to determine their temperature values. From the results collected, the temperatures of the nanosatellites change drastically depending on the presence or absence of heat dissipation. This also depends on the type of the considered coating. It was also noticed that the temperature inclined with the choice of surface coating which was stipulated by the α/ε ratio. Therefore, it would be wise to choose the right surface coating at the very beginning of the design.

“…in this study thermal strap and Single layer insulation have been implemented. due to its reflective and absorbing qualities, multi-layer insulation (Mli) blankets are recommended for space applications since they help the spacecraft in preventing any form of radiation [16]. thermal straps are passive heat transfer devices that are frequently used on space missions to conduct the heat from inaccessible regions of the spacecraft and radiate into space.…”

TransienT Thermal analysis of 1U modUlar CUbesaT based on Passive Thermal ConTrol sysTemCube Satellites are miniaturized satellites used for space research with a mass of not more than 1.33 kg per unit. they are widely used in space applications because of its low cost of manufacturing and flexibility of applications. Since, they use commercial off-the-shelf components, thermal consideration of internal components of 1-unit cube satellites becomes a necessity. in this paper, transient thermal analysis of a 1-unit cube satellite is conducted to analyze its behavior during the first 29 seconds of orbit insertion from the launch vehicle. transient thermal analysis yielded a temperature range that exceeded the optimum limit. as a result, to reduce heat dissipation, two main types of thermal management systems for satellites: active control and passive control systems are included. to maintain critical components at their operating temperature, a passive thermal control is implemented. thermal strap and multi-layer insulation are used to analyze internal components of 1-unit cube satellite. using graphite fiber thermal strap and aerogel multi-layer insulation for internal components, the 1-unit modular cube satellite is found to be more suitable under low earth orbit conditions.
