Environmental Absolute Reliability Thermal Shock Test Chamber GB/T 2443.1-2001

Standard Environmental Thermal Shock Test Chamber Tested for Absolute Reliability

Applications

Thermal shock chamber is a chamber which use method of environmental testing that subjects a product to alternating extremes of high and low temperatures. The application of rapid temperature cycling is the most effective manner of creating premature failures of products in the production phase. We can simulate all natural temperatures which, when considering the fields of aviation and aerospace, range between -80 °C and +220 °C. It is used to test the capability of material structure or composite material to withstand the continuous environmental changes between extremely high temperature and low temperature during a short period.

Features

1) Test samples don't move. Thermal shork chamber in each zone for peak demand of heating and cooling.

2) Horizontal airflow design assures uniform results

3) Extremely compact systems with a vertically sliding door for added space savings

4) Utilizes the latest refrigeration technology: electronic expansion valve and high-tech compressor. Provides extra thermal energy to efficiently meet the MIL-STD 883 requirements.

5) Temperature recorder provides 24 hour part temperature recording as the load travels from zone to zone. 

6) Using touch-control graph control as operation interface, easy to operate.

7) The system can be used for automatic Circulation Shock or manual selective shock, capable of setting two zones or three zones shocks as well as cold and thermal shock start-up.

8) Custom-made and optional accessories available.

Working Principle

There are three chambers used to perform thermal shock testing, high-temperature chamber, low-temperature chamber and test chamber. Sample is placed in the test chamber, more extreme temperature than test temperature can be set in high-temperature chamber and low-temperature chamber. When doing low temperature testing, cold chamber door open, and low-temperature chamber working together with test chamber.

When converted into high-temperature test, cold chamber door closed, hot chamber door are opened, and test chamber working together with high-temperature chamber. Conversion of mechanical action (transferring from high temperature to low temperature or low temperature to high temperature) can be completed in less than 1second, and the temperature can be quickly stabilized.

During the whole test, test sample is no need to be moved, and without any human intervention.
