Description

Technical Field

[0001] The utility model relates to the technical field of test boxes, in particular to a temperature shock test box. Background Art

[0002] The temperature shock test chamber is an essential test equipment for the metal, plastic, rubber, electronic and other material industries. It is used to test the material structure or composite material to see how well it can endure the continuous environment of extremely high temperature and extremely low temperature in an instant, so as to detect the chemical changes or physical damage caused by thermal expansion and contraction of the sample in the shortest time. The test chamber is subjected to impacts in different temperature sections, and the multi-stage evaporator structure is cut off accordingly. The evaporation area is controlled to match the expansion valve with the cooling capacity. The output of the refrigeration system is used to reasonably reduce the output of the heater neutralization to achieve constant energy saving. There is also an independent ventilation valve, which operates to introduce ambient air when the exhaust temperature returns to normal. The temperature shock test chamber adopts a vertical body and two hot and cold boxes. The method of using a basket to convert the experimental area where the test sample is located is adopted to achieve the purpose of the hot and cold shock test. This structure minimizes the heat load during hot and cold shocks and shortens the temperature recovery time. It is also the most reliable and energy-saving way of hot and cold shocks.

[0003] However, it still has some disadvantages. For example, when using the traditional temperature shock test chamber, when taking out the test product, the human body needs to enter the test chamber to take out the test product. When the human body accidentally touches high temperature and low temperature, it is easy to cause human tissue injury, which has certain safety hazards. In addition, the test chamber may have gas leakage, which will cause erroneous test results of the test product and affect the final test quality of the test product.

[0004] In order to solve the above problems, a temperature shock test chamber is proposed in the present application. Utility Model Content
