Vacuum environment simulation In the thermal vacuum test, the first step is to simulate the vacuum environment of space. When spacecraft operate in space, there is almost no air around them, meaning they are in a high vacuum state. To simulate this environment on the ground, a vacuum system is used, including vacuum pumps, gas condensers, and pressure sensors, etc. The gas inside the test chamber is evacuated to make the internal pressure approach the vacuum state. Usually, the vacuum requirement of the thermal vacuum test is better than 6.5x10^-3 Pa to ensure that the simulated vacuum environment is close enough to the real space environment.If you need more models about our test equipment, please reference our ： https://www.chamber-testing.com/ Temperature cycling simulation In space, spacecraft undergo significant temperature changes because they are exposed to solar radiation and cosmic darkness. The thermal vacuum test simulates these temperature cycles through heating systems and cooling systems. The heating system can use resistance wires, radiation heaters, or high-frequency heaters, etc., by controlling the current and voltage of the heating elements to regulate the temperature. The cooling system may use low-temperature media such as liquid ammonia. During the test, the spacecraft is heated to a high temperature (for example, +65°C) and cooled to a low temperature (for example, -35°C), and cycles between these extreme temperatures to test its performance under temperature changes.

A vacuum test chamber is a type of testing equipment capable of simulating specific environments. As an important type among them, the thermal vacuum test chamber is a comprehensive testing device that simulates high vacuum and alternating high and low temperature environments. It can simulate the real state of products in the usage environment and test the performance and reliability of products under high temperature, low temperature and vacuum conditions. It is mainly used for reliability testing and performance verification of products such as spacecraft components, satellite modules, precision electronic instruments, and optical devices. The thermal vacuum test chamber mainly simulates a high-temperature and high- vacuum environment through the coordinated action of a vacuum system and a heating/cooling system. The vacuum system expels the gas in the vacuum chamber through components such as vacuum pumps, gas condensers and pressure sensors, bringing the internal pressure close to a vacuum state. The heating system is usually composed of resistance wires, radiant heaters or high-frequency heaters, etc. The heating power and temperature are regulated by controlling the current and voltage of the heating elements. In practical operation, a high vacuum environment is formed by the combination of a main pump (such as a mechanical pump) and a molecular pump to evacuate the vacuum chamber. The heating system heats or cools the chamber through electric heating wires or liquid nitrogen, creating a uniform temperature field in the heat sinks of the chamber, simulating a space environment with both vacuum and a wide temperature range (such as -100℃ to 125℃).If you need more information about the models of our testing equipment.

In the aerospace field: Components of aircraft and assemblies of spacecraft, etc., need to be strictly tested in environments with high and low temperatures and low air pressure. 2. Electronics industry: From chips in mobile phones and computers to various electronic components, integrated circuits, circuit boards, etc., by simulating different temperature and air pressure conditions, their working conditions in harsh environments are detected to improve product quality and stability. Low-pressure test chambers usually adopt an integral combination structure, consisting of an insulated box body at the front, a refrigeration and vacuum unit at the rear, and an electrical control system on the side. Among them, the box body is the core pressure-bearing part, responsible for maintaining the changes in internal air pressure and ensuring the sealing and pressure resistance of the equipment during the process of air pressure change. The insulation box is made of highly efficient heat insulation materials, which can prevent the interference of external temperature on the test environment and ensure the accuracy of the test results.
