Defrost design advantages of two boxes of hot and cold shock test chambers

Two boxes of cold and thermal shock test chamber is used to test the material structure or composite materials, in an instant through the * temperature and extremely low temperature of the continuous environment can withstand the degree, in order to test its chemical changes or physical damage caused by thermal expansion and contraction in a short period of time, the applicable objects include LED optoelectronics, semiconductors, components, LCD screens, metals, plastics, rubber, electronics and other materials, can be used as the basis or reference for
its product improvement.

Widely used in aerospace, electrical and electronics, instrumentation, materials and equipment, spare parts and other analog specimens in the surrounding atmosphere temperature under the conditions of rapid changes in the adaptability test and the safety test of electronic components to provide reliability tests, product screening, etc.
, at the same time, through this test, product quality control
.

Two boxes of cold and thermal shock test chamber product characteristics description: The control system adopts the color touch screen in Chinese and English to display the button operation, the appearance is simpler and more generous, and the operation setting is simple
.

The basket is switched and transferred in the high and low temperature room, using pneumatic control, the conversion time is short, the temperature recovery time is short, the temperature change speed is fast, the overall structure of the equipment is compact, the volume is small, the two-box method is adopted, the temperature uniformity range of the studio is improved, but the specimen has been in motion, and the studio cannot leave a test hole, so it cannot be charged, with a signal, with an air source test
.

The box processing adopts CNC machine tool processing and molding, beautiful and generous shape, and adopts no reaction handle, which is easy to
operate.

The housing is made of high-quality carbon steel plate.
Phosphorossed electrostatic spray treatment or stainless steel matte line hair grain treatment, the internal materials are made of high-grade stainless steel
.

Equipped with a large observation window lighting to keep the box bright, and the use of heating body embedded tempered glass, at any time to clearly observe the situation
in the box.

Defrosting design of two boxes of cold and thermal shock test chamber: The use of high temperature and high pressure heat energy discharged by the compressor of the refrigeration system, controlled by the solenoid valve servo energy adjustment system, the thermal energy is smoothly transported to the evaporator as an automatic defrost circuit, so as to achieve the effect of cold and heat balance, this design can ensure the long-term normal operation
of the entire impact test process.

The traditional cold and thermal shock test chamber does not have this function design, the traditional cold and heat shock box when the cryogenic box evaporator frost needs to start the electric heating function defrosting, not only does not save energy and there is a possibility of leakage of hidden crime, but also due to defrosting caused by test interruption.
The company's newly developed defrost design largely avoids similar situations
