How the cryogenic test chamber achieves a stable low-temperature environment

Cold and thermal shock test chamber on the market is divided into two categories, one is two-compartment type, including high temperature region and low temperature region, the test object were in two different temperatures in the area of the test, hot and cold alternating test; the other is three-compartment type, in addition to high temperature and low temperature area, there is also a test area, and two-compartment type is different, three-compartment type does not need to be tested directly in the test area, only through the air compression method, the Two different areas of air compression to the test area can be, compared with the two-compartment type, three-compartment type easy to operate some.

Cold and thermal shock test chamber can be used in electronic components, automotive parts, plastics, aerospace, electronic chips, conductors, ceramic magnets and other different types of industries. The principle of the device is through the different temperatures, the experimental object for temperature shock test, with a shorter period of time will be a rapid shift in temperature to form a test shock, test out the test object in the extreme temperature of the degree of damage, as well as the degree of damage resistance. Usually, the test object in the case of thermal expansion and contraction, will be caused by physical and chemical damage, to test the damage caused by the test as a standard, to further reduce the degree of damage to the test object in extreme temperatures.

The main feature of the thermal shock test chamber is that the temperature can be achieved in a very short period of time to achieve a rapid change in temperature, simulating the natural conditions of the environment, the specific can be expressed in a few seconds from 100 ℃ high-temperature environment can be transformed into a low-temperature environment of minus 60 ℃, to improve the rate of the test, cost savings.

In different test conditions, the required test equipment is different, according to the actual situation to choose the right equipment. Cold and thermal shock test chamber in the initial development stage, you can find some of the shortcomings of the product early, such as in extreme temperatures to maintain normal operation, in order to improve as early as possible, to prevent the formal commissioning of the larger losses caused by the aftermath of; environment, temperature as a screening conditions, screening out the product performance is a little better.
