The thermal vacuum test chamber is a ground test equipment used to simulate the high vacuum, extreme temperatures and dark background that spacecraft encounter in the space environment. It is widely applied in the reliability verification of products in the aerospace and electronic semiconductor fields.
The TESTEQ thermal vacuum chamber comes with a set of impressive technical specifications. It can reach a high vacuum level of 5.0×10−7 mbar, and the no - load vacuum level at room temperature is also 5.0×10−7 mbar. The pressure regulation in multiple ranges at room temperature spans from 1.0×10-2 to 1.0×10−6 mbar/Torr. The vacuum cube leak rate is extremely low, at ≤ 1×10-9 std/cc/sec, ensuring a highly stable vacuum environment.
In terms of temperature performance, the chamber offers excellent temperature uniformity of ±2℃. It has a rapid temperature - changing ability. The temperature rising rate from +70℃ to - 50℃ is at least 3℃/min, and the falling speed rate from +20℃ to +125℃ is also ≥ 3℃/min.
Thermal vacuum (TVC) chambers, like the one procured by China's space agency, are designed to replicate the temperature and pressure conditions of the space environment. These chambers can generally achieve a temperature range from - 180°C to +145°C. Moreover, by using a cryocooler within the chamber, an extremely low temperature of 2.6K can be reached.
This procurement is expected to enhance China's space - related R & D capabilities, allowing for more in - depth research and more reliable testing of space equipment before they are lau
