What is Large Thermal Vacuum Chamber?
Large Thermal Vacuum Chamber is an environmental testing chamber that can instantly switch from high temperature to low temperature. It is used to test the degree to which material structures or composite materials can withstand continuous environments of extremely high and low temperatures in an instant, and can detect chemical changes or physical damage caused by thermal expansion and contraction of samples in the shortest time.

Inner chamber structure
The internal structure of a Large Thermal Vacuum Chamber generally consists of three areas: a high temperature area, a low temperature area, and a test area. The samples in the test area are subjected to alternating cycles of high and low temperatures to test their performance changes at different temperatures. Common test indicators include temperature change rate, temperature stability, thermal conductivity, etc.
