Product Description

Application

Thermal vacuum test chambers are widely used in aerospace, electronics, automotive and other fields to test the performance and reliability of products in these fields. For example, in the aerospace field, thermal vacuum test chambers can simulate the real state of products at high altitudes and test the performance and reliability of products under high and low temperature conditions. In the electronics field, thermal vacuum test chambers can test the performance and reliability of products under vacuum conditions, such as vacuum tubes, electron microscopes and other equipment. In the automotive field, thermal vacuum test chambers can test the performance and reliability of automotive parts under high and low temperature conditions to ensure the safety and reliability of the car.

In short, the thermal vacuum test chamber is an important testing equipment that can simulate the real state of the product in the use environment and test the performance and reliability of the product under high and low temperature conditions. This article introduces the structure and working principle of the thermal vacuum test chamber and discusses its application fields.


One key aspect of the testing includes the use of thermal vacuum chambers (TVC) to replicate the ultra-cold temperatures and the airless vacuum of space.  The extreme cold and absence of air pressure in TVCs will help identify flaws or weaknesses in the equipment tested.

Once equipment to be tested is placed inside the TVC, the air is evacuated. When the air, and accompanying air pressure, are removed, gas trapped in materials is released, and outgassing begins to occur. The released gases, and other impurities inside the chamber, will begin to evaporate and may condense on the equipment, potentially making it less accurate or even unusable.

To reduce the temperature inside the chamber, and to remove lingering gases and impurities from the chamber, TVCs typically utilize cryopumps. These pumps, located at the bottom of the chambers use cryogenic gases, such as liquid nitrogen (LN2) or helium (He), to super-chill the air and the surfaces of the cryopump to between -208 Celsius and -261 Celsius.  As the air in the chamber passes over the surfaces, gases such as oxygen, nitrogen, helium, and hydrogen instantly freeze to the surfaces of the cryopump and are, effectively, removed from the chamber.

Meet the standards

Standards for thermal vacuum testing:

"GJB 3758-99 Thermal Simulation Method for Satellite Vacuum Thermal Test"

At present, there are very few laboratories that can conduct thermal vacuum tests. They mainly include the Environmental Reliability and Electromagnetic Compatibility Test Center, the Aerospace Environmental Reliability Test and Inspection Center, etc.

Machine structure


Structure of thermal vacuum test chamber

Thermal vacuum test chamber usually consists of vacuum chamber, heating system, refrigeration system, control system and measurement system. Among them, the vacuum chamber is the core part of the test chamber, which is used to simulate the real state of the product in the use environment. The heating system is used to heat the product to the required temperature, and the refrigeration system is used to keep the product at a low temperature during certain experiments. The control system is used to control the temperature, pressure and other parameters of the test chamber, while the measurement system is used to monitor the performance and parameters of the product.

Working principle

Working principle of thermal vacuum test chamber

The working principle of the thermal vacuum test chamber is mainly achieved through the following steps:

1. Vacuuming: The vacuum chamber of the test chamber is evacuated to a vacuum state to simulate the actual state of the product in the use environment.

2. Heating: The product is heated to the required temperature through the heating system to test the performance and reliability of the product under high temperature conditions.

3. Refrigeration: In some experiments, the product is kept at low temperature through the refrigeration system to test the performance and reliability of the product under low temperature conditions.

4. Measurement: Monitor product performance and parameters through measurement systems to evaluate product performance and reliability.

5. Control: Control the temperature, pressure and other parameters of the test chamber through the control system to ensure the accuracy and repeatability of the experiment.
