Decoding Solar Panel Heat Transfer in Spacecraft: A Thermal Engineer's Perspective
Welcome to Nitrexo's Thermal Engineering Blog! Today, we delve into the intricate world of spacecraft thermal dynamics, specifically focusing on the thermal analysis of solar panels. Join us as we unravel the challenges posed by extreme temperatures in space and explore the most effective heat transfer paths between solar panels and spacecraft structures.
The Space Thermal Challenge:
Spacecraft, like those for earth observatory missions, face a harsh thermal environment. Solar panels, the lifeline of these missions, endure extreme temperature swings from +120˚C during sun exposure to -170˚C during eclipse. This presents a unique challenge that our thermal engineers at Nitrexo aim to unravel.
The Role of Thermal Control Systems:
To overcome temperature variations and ensure optimal spacecraft performance, thermal control systems (TCS) become indispensable. These systems manage heat transfer paths within the spacecraft, maintaining components within their temperature limits. Effective TCS is vital for the success of any spacecraft mission.

Mathematical Modeling of Solar Panels:
Our thermal engineers employ a one-dimensional model with heat conduction equations to understand the energy balance within solar panels. We consider external heat fluxes and radiation heat exchange to simulate real-world scenarios.
Using advanced simulation software Digital Engineer®️, we apply the principle of conservation of energy to predict temperature evolution in a heated operating environment. The heat conduction equation is solved to understand the complex interplay of heat transfer in different directions.
Numerical Modeling for Real-World Insight:
In the complex world of spacecraft systems, we turn to numerical modeling for practical insights. Nitrexo Digital Engineer ®️ space thermal simulation solver allows us to simulate solar panel heat flux effects on a real-case satellite in low-earth orbit, providing valuable data for analysis.
Our thermal engineers compare three thermal paths – G10, Aluminum 6061, and Titanium. G10 and Titanium emerge as effective isolators, significantly reducing the impact of solar panel heat flux on the satellite body. In contrast, Aluminum 6061 does not provide substantial heat reduction.
In conclusion, the thermal analysis underscores the critical importance of selecting the right thermal paths.
In Conclusion:
At Nitrexo, we understand the complexity of implementing thermal analysis, often requiring extensive time and resources.
