Cold and Dark Environment Simulation Thermal Vacuum Test Chamber ECSS-E-ST-10-03C

Simulation of solar irradiation environment

The electromagnetic radiation of the sun is equivalent to the blackbody radiation of 6000K and is the main external heat source for spacecraft. Spacecraft orbiting the Earth are also exposed to the Earth's albedo and infrared radiation while in orbit. Solar simulators typically use carbon arc lamps or high-pressure short-arc xenon lamps as light sources, and are equipped with off-axis, coaxial or divergent optical systems to simulate the intensity and energy spectrum distribution of sunlight. Due to the high cost of manufacturing and testing solar simulators, for most spacecraft with less complex shapes, the method of heat flux simulation is often adopted instead of solar simulation.

Test standards and related laboratories

The current standard for thermal vacuum tests is GJB3758-99. The laboratories that conduct thermal vacuum tests mainly include the Environmental Reliability and Electromagnetic Compatibility Test Center, the Aerospace Environmental Reliability Test and Inspection Center, etc.If you need more models about our test equipment, please reference our ：chamber-testing（Click）com 

The thermal vacuum test chamber is an important testing device that can simulate the real state of products in the usage environment. It is used to test the performance and reliability of products under high temperature, low temperature and vacuum conditions, and is widely applied in fields such as aerospace, energy and electronics.
