The two zone thermal shock chamber is used to test the degree to which structural materials or composite materials can endure under the continuous environment of very high and very low temperatures in a short period of time, testing the chemical changes or physical damage caused by thermal expansion and contraction of materials and products. Cold and heat impact tester is widely used in metal, plastic, rubber, cable, and wire industry quality testing test, and can be used as the basis for product improvement or reference. There are two-box and three-box cold and heat impact testers. This article focuses on the two zone thermal shock chamber.
Here is the content list:
Two zone thermal shock chamber, as the name implies, has only two studios, one for high temperature and one for low temperature, when the impact work, only need to move the test piece to the opposite studio through the basket can be, energy loss is relatively small, compared with the three-chamber type, the configuration is small, the failure rate is correspondingly low.
The main structure of the two zone thermal shock chamber consists of a pre-heating chamber, a pre-cooling chamber, a refrigeration system, a heating system, an air duct system, and an electrical control system. The pre-cooling chamber is located in the upper part of the test chamber, the pre-heating chamber is located in the lower part of the front of the test chamber, the refrigeration machine is located in the lower part of the test chamber, and the electrical control cabinet is located on the right side of the test chamber. The simple structure and easy operation are the distinctive features of this climatic chamber.
Two zone thermal shock chamber has no room temperature dwell stage, only high and low-temperature dwell, high and low-temperature dwell stage at the beginning of the obvious overshoot phenomenon. The two zone thermal shock chamber has a faster changeover time between high and low temperatures and is more adaptable than the three zone chamber to withstand instantaneous changes in ambient temperature.
The two chambers of the two zone thermal shock chamber are a high-temperature chamber and a low-temperature chamber, with a basket in the middle. When testing, the sample is placed in the basket and when doing the high-temperature test, the basket is mentioned in the high-temperature chamber, and vice versa for the low-temperature test. Fast temperature speed; compact structure, generally small volume. Short changeover time; the product needs to be moved during the test. Can be used as a thermal shock chamber and can be used as a separate high-temperature chamber or a separate low-temperature chamber. These advantages are the reasons why the two zone thermal shock chamber has become the mainstream of the market.
