Two box high and low temperature impact test chamber

1Two box high and low temperature impact test chamberOverview:

It is also called high and low temperature impact test chamber (Taiwan, China, China is called cold and hot shock machine). They can be used for material research and industrial production of bulk or electronic and electrical components, automation components, semi-finished products, metals, chemical materials, communication components, defense industry, aerospace, military industry, BGA, PCB substrate electronic chips. They can be tested for their ability to withstand continuous temperature changes of high and low temperatures in an instant, and test the chemical changes and physical damage caused by thermal expansion and contraction under rapidly changing temperature differences.

2、 Structural construction:

1. Box body: The box body of the cold and hot shock test box is usually made of imported SUS304 corrosion-resistant stainless steel plate, with a beautiful and elegant design, reasonable process, and surface treated with electrostatic spraying.

2. High temperature zone and low temperature zone: These are the two main parts of the test chamber, used to generate high and low temperature environments respectively, to simulate the performance of the product under temperature conditions.

3. Testing area: This is the place where the product to be tested is placed, usually located between the high temperature zone and the low temperature zone, for conducting thermal shock testing.

Refrigeration unit: The refrigeration unit is an important component of the test chamber, used to provide refrigeration effect, enabling the high and low temperature zones to reach the required temperature range.

4. Electrical control cabinet (system): The electrical control cabinet is the brain of the test box, responsible for controlling and managing the entire test process, including temperature control, cycle control, etc.

5. Compressor: The compressor is the core component of the refrigeration unit, responsible for compressing low-temperature and low-pressure gas refrigerant into high-temperature and high-pressure gas refrigerant, thereby achieving refrigeration effect.

6. Thermal insulation material: Thermal insulation material is used to reduce heat exchange inside and outside the box, and maintain stable temperature inside the test box.

Sample rack: The sample rack is used to place the product to be tested, usually made of stainless steel material and has a certain load-bearing capacity.

7. Throttle structure: Throttle structures (such as capillary tubes or expansion valves) are used to convert liquid refrigerants at room temperature and high pressure into low-temperature and low-pressure gas-liquid mixtures through flow restriction, further achieving refrigeration effects.

8. Internal air circulation system: The internal air circulation system uses high-power centrifugal fans and stainless steel blades to circulate air, ensuring the uniformity of temperature and humidity inside the test chamber.
