Product details：
Thermal shock test box testing equipment, metal plastic, rubber and electronic materials industry necessary for testing, the structure of the material or composite materials, the continuous environment in an instant by a very high temperature and low temperature under intolerable level, the changes in chemical or physical damage in the shortest period of time the test due to thermal expansion and contraction caused by.

1. Classification and overview：
The cold and hot impact test chamber can be divided into 3 kinds: three box gas cold and hot impact test box, two box hanging basket cold and hot impact test box, and liquid cold and hot impact test box. In these three kinds of thermal shock test box, gas type cold shock test box three box because of the price for the use by most; use basket type cold shock test box two boxes and three boxes of gas type cold shock test box, but its performance is more excellent, high configuration and test conditions of higher characteristics the price is not cheap. But with the requirements of the quality and performance of the products to be tested is more and more high, the two box basket type thermal shock test box more and more applications; liquid thermal shock test box used less, because of its high price, at present, our only encounter the semiconductor industry and the PCB industry in. The cold and heat shock test box, which we generally say, refers to the three case gas cold and heat shock test case.
2. Product parameter specification：

3. Product features：
1.Gas type cold shock test box three boxes of equipment is divided into high temperature area and low temperature area, the three part of the test area, with unique structure and heat storage, heat storage effect, application of hot and cold air path switching into the sample, so the impact of hot and cold test, tested for not moving way.

2. three box gas cold and heat shock test cases are used in Chinese and English display control system of large liquid crystal LCD (320 x 240 Dots).

3. high program memory capacity, can be set to store 100 groups of programs, the maximum cycle set 9999 Cycles, the maximum set of 999 Hrs 59Mins per period of time

4., the three box gas cold and hot impact test box has the RS-232C communication interface device. It can be manipulated online / controlled by computers, edit / record and two groups of dynamic contacts (Time Signal Relay), and it is easy to use.

5. the function of 2 Zone or 3 Zone can be selected when the cold and heat shock conditions are executed.

6. with full automatic, high precision system circuit, any piece of machine action, completely locked by P.L.C..

7. machine parts are equipped with automatic motor circuit and warning signals.

8. when it is found that the input power is unstable, it has an emergency shutdown device.

9. can be expanded: liquid nitrogen low temperature auxiliary system, temperature automatic recorder, operation recording software.

4. Performance characteristics：
1.Compressor: high performance imported fully enclosed scroll compressor, safety, reliability, energy efficiency ratio is high.

2. fan: the centrifugal fan with high performance and low noise has the advantages of large air volume, high static pressure, low noise and smooth operation.

3. heat exchanger: the use of our factory to import the American OAK production line processing, so that heat exchange efficiency of heat exchanger greatly improved.

4. shell: processing the Japanese AMADA equipment imported by our factory to ensure the quality of the exterior. The frame adopts the popular aluminum alloy frame structure at home and abroad, and the whole structure is compact and beautiful.

5. heater: the high efficiency electric heating tube with ribs is adopted, which is small in volume and high in heat efficiency.

6. refrigeration accessories: expansion, filter, solenoid valve, high and low pressure controller, pressure meter all use imported brand accessories.

7. defrosting parts: high reliability components and high performance control methods are adopted to ensure the safety and reliability of the frost melting, and the treatment of the frost layer is complete and thorough so as to increase the heat transfer performance of the unit.

8. insulation layer: polyethylene high foam material, small thermal conductivity, high water resistance, anti aging, flame retardant, non-toxic.

9. control mode: use high performance control instrument. The control precision is high and the reliability is good. The remote control interface can be reserved for the control instrument, which can facilitate the remote centralized control of the user and save the management manpower.
