Thermal vacuum experiment for aerospace engineering supplies and materials must do experiments, thermal vacuum experiments can assess the thermal design of aerospace supplies and materials, to find its environmental adaptability in the thermal vacuum environment, the general thermal vacuum chamber of the general temperature control range between -100 ºC and 150 ºC, the limit of the vacuum degree of IE_5Pa, the existing technology in the assessment of the special aerospace materials with the adaptability of the vacuum environment, need to carry out different thermal vacuum experiments under temperature conditions, the general thermal vacuum chamber can not meet the experimental temperature range, for this reason, we invented the thermal vacuum test chamber. Existing technology in the assessment of special aerospace materials to adapt to the vacuum environment, need to carry out different temperature conditions of the thermal vacuum experiment, the general thermal vacuum chamber can not meet the temperature range of the experiment, for this reason, we have developed a thermal vacuum test chamber.

Thermal Vacuum Chamber Structure
1. The test equipment adopts frame structure, the cold and heat source unit is arranged independently, which reduces the influence of vibration on the vacuum chamber, the vacuum unit and the chamber are combined into one, the appearance is compact and beautiful, and the overhaul of the equipment is well considered.
2. The vacuum vessel is made of non-magnetic SLS304 stainless steel with excellent mechanical properties, horizontal structure, one end of which is made of movable disc-shaped head as hatch (opening direction: facing the box door and rotating to the right), and the other end of which is the head: the inner surface of the vessel is mechanically polished in order to reduce the outgassing of the material.
3. Gauge interface: 4 KRF25 gauge interfaces are installed on the tank, two are spare.
4. Heat sink: Adopting purple copper plate and purple copper pipe with excellent thermal conductivity and welding performance, the inner surface is sprayed with special black matting paint to improve its radiation power.
5. Bottom plate: the bottom plate is active non-independent temperature control bottom plate (Note: users can choose non-temperature control bottom plate or independent temperature control bottom plate).
6. Hatch and sealing: movable disc-shaped head for the hatch, special floating hinges, screw locking mechanism, easy to open and close: hatch sealing using professional release "amount of small vacuum 0-type seals, easy to replace.
7. Flange: A 20m blind flange is arranged on the left and right sides of the tank for installing the vacuum connector, which is provided by the user.
8. Observation window: configure a 20m diameter quartz glass observation window on the main door
