Thermal Shock Chambers Overview:
KOMEG thermal shock chambers meet the demands of today's environmental stress screening with proven performance in installations around the world. Our direct transfer method between hot and cold is an economical method to achieve rapid part temperature change for ESS or thermal shock.
Thermal shock test chamber is requisite testing equipment in metal, plastic, rubber, electronics and other industries. It is used for testing the material structure or composite material’s tolerance degree when exposed instantly in extremely high temperature and extremely low temperature environment continuously, so that whose chemical or physical damage due to thermal expansion and contraction can be detected in shortest time.
3-Zone Thermal Shock Chambers Working Principle:
The three-zone type thermal shock 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. During low temperature test, 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 1 second, and the temperature can be quickly stabilized.
During the whole test, test sample is no need to be moved, and without any human intervention.
Below are differences between3-zone and 2-zone thermal shock chamber:
3-zonethermal shock chamber:
three chamber in total: test space, high temp. chamber and low temp. chamber;
Advantage: slight limitation for test sample’s weight, the test sample keep still, this can reduce the impact to samples by moving it, can be used for on-load testing.
Compared with 2-zone type, relatively low failure rate, low cost.
Disadvantage: long conversion time
2-zonethermal shock chamber:
only two chambers: high temp. Chamber and low temp.chamber
Advantage: short conversion time, smaller space needed
Disadvantage: test sample moving. test samples’ size is limited by the basket size
Packaging:
Climatic thermal shock test chamber are covered with air bubble film before put them into the strong plywoodcase, which not only has good shock absorption, impact resistance, heat sealing and also has the advantages of nontoxic, odorless, moisture corrosion, crash-proof, etc.
