Working Principle of Thermal Vacuum Test Chamber

Sanwood Technology's Thermal Vacuum Test Chamber is a device used to simulate space or other extreme environmental conditions. It combines two extreme conditions, high temperature and vacuum, to evaluate the performance, reliability and durability of test specimens under these conditions.

Basic Composition of Thermal Vacuum Test Chamber

Sanwood's Thermal Vacuum Test Chamber consists mainly of a sealed test chamber and a control system. The interior of the chamber is usually made of high temperature and vacuum resistant materials to ensure stability and safety in high temperature and vacuum environments. The control system consists of temperature controllers, vacuum pumps, heating elements, gas valves and other key components.

Working Principle of Thermal Vacuum Test Chamber

Sanwood's Thermal Vacuum Test Chamber can provide a vacuum of more than 10^-3Pa, the internal ring heat sink can achieve the simulation of the cold black space environment, the temperature control base plate can shorten the temperature stability time of the specimen under high vacuum, the temperature measurement system can achieve the monitoring of the test process and data recording.

Main technical indexes of Thermal Vacuum Test Chamber

The main technical indexes of thermal vacuum tester include temperature control range, vacuum chamber size, ultimate vacuum, working vacuum, temperature resolution, temperature fluctuation, power supply voltage and so on. For example, the following models of Thermal Vacuum Test Chamber technical indicators:
