Advantages include accurate simulation of temperature changes, ease of operation, high reliability and stability. At the same time, the thermal shock test chamber can greatly improve the quality and reliability of the product, so as to meet the demand for high-quality products in the industrial field.

However, there are also disadvantages of the thermal shock test chamber, which are mainly reflected in the relatively high equipment, large space occupation and high maintenance costs. Therefore, when purchasing and using a thermal shock test chamber, it is necessary to consider its advantages and disadvantages, and make a reasonable choice according to your own needs and actual conditions.

In order to ensure the correct use of the thermal shock test chamber, avoid damage caused by improper use of the instrument and products, and improve the validity, authenticity and accuracy of product test data. Equipment operators should pay attention to the daily inspection of instruments, and at the same time pay attention to the following operating specifications:

1.Thermal shock test chamber is in operation, please do not open the chamber door unless necessary.

2.Avoid turning off and then turning on the refrigeration unit in the three-point smile.

3.Do not connect the power supply used for the test sample to the power supply of the machine.

4.The lights should be turned off at all times except when necessary.

5.During the test, when the temperature of the cryogenic chamber exceeds 55, the chiller should not be turned on.

6.Circuit breakers, over-temperature protectors, please check regularly.

7.Before doing low temperatures, the studio should be wiped dry and dried for 1 hour at 60 hours.

8.It is forbidden to test **, flammable and highly corrosive substances.

9.The basket rails and racks should be lubricated regularly.

10.In any cross-section perpendicular to the prevailing wind direction, the sum of the test load cross-sectional areas shall not be greater than one-third of the working cross-section.

11.The sample to be tested should be fixed in the middle of the sample frame as much as possible, and should not be placed on one side at will, resulting in the tilting of the basket.

The major system composition of the thermal shock test chamber needs to be suitable for the adaptability test of major electronics, electricians and other equipment under the conditions of rapid changes in the ambient atmospheric temperature, and it is also a good assistant for screening the beginning of the failure of its components. Detect the structure of each material and composite material, so that under a certain temperature condition, after extremely high temperature and extremely low temperature continuous environment to endure the degree, the internal structure is inseparable from the cyclic operation of a variety of systems and the mutual promotion between systems. The advantages of the three systems are very prominent, and the use of them is high-configuration, and the quality is considerable.

Category 1: Control systems. It adopts microcomputer electronic digital control mode, which is precise, accurate, stable and reliable; It is also a color touch LCD, Chinese and English microcomputer temperature control and liquid crystal touch screen direct button type control;

Category III: Refrigeration systems. The refrigeration system is to ensure the cooling rate and minimum temperature requirements of the test chamber, so that the test chamber is a binary cascade air-cooled refrigeration system composed of a set of compressors, and the cascade refrigeration system includes a high-temperature refrigeration cycle and a low-temperature refrigeration cycle, and uses HFC environmentally friendly refrigerant, the design of the binary ultra-low temperature refrigeration system is exquisite, the cooling is fast and the efficiency is high.

The three types of systems are analyzed and illustrated to further understand the components of the thermal shock test chamber. In the multi-functional thermal shock test chamber to perform a variety of tests, temperature control and temperature range values are often the most important.

<>1. Placement of samples: In fact, when choosing a thermal shock test chamber, the first business will consult the volume of the sample to ensure that there will be no test errors due to the excessive volume of the sample and the lack of smooth air circulation in the studio.

2. Check before the experiment: Before the test, you must turn on the power cord of the equipment and check whether it is correctly grounded, whether the external water cooling system is connected normally, and whether the water source used is clean.

3. Test conduct: In order to ensure the safety of the operator and the accuracy of the test results, we can not open the door frequently during the test, and before setting the temperature, we also need to ensure that the door of the cold and thermal shock test chamber is locked to avoid temperature leakage and cause the required temperature in the studio to be unable to reach the required temperature.

4. The end of the experiment: After the end of the test, the power supply of the equipment must be cut off to avoid leakage, and it is also necessary to pay attention to the fact that the user should not face the door of the box when taking the sample, so as to avoid scalding and frostbite caused by the cold or hot air rushing out of the studio.

There is so much to say about the use of the thermal shock test chamber, and we should strictly follow the instructions given by the manufacturer in the process of use, so that we can make the life of the equipment longer.
