A cold and hot impact box is a device used to test the durability of electronic products in environments with drastic temperature changes. It can simulate the use of electronic products in extreme temperature environments, thereby evaluating the reliability and durability of electronic products. The cold and hot impact chamber usually consists of two independent testing chambers, one for high-temperature testing and the other for low-temperature testing. These two testing rooms are connected by a rotatable test stand, allowing electronic products to quickly transition between high and low temperatures. This article will discuss the use and maintenance methods of cold and hot impact boxes.

Firstly, let's understand the usage of cold and hot shock boxes. Before using a cold and hot shock box, it is necessary to first place the electronic product inside the box, and then set the required temperature range and testing time. During the testing process, the cold and hot impact box will automatically control the temperature and complete the test within the set time. After the testing is completed, it is necessary to remove the electronic product from the box and conduct data analysis and result evaluation.

When using a cold and hot shock box, it is necessary to pay attention to the following aspects. Firstly, it is necessary to ensure that the size of the electronic product is suitable for the size of the cold and hot impact box. If the electronic product is too large, it may not fit into the box, and if it is too small, accurate test results may not be obtained. Secondly, it is necessary to ensure that the temperature range and testing time are set correctly to ensure the accuracy of the testing. Finally, during the testing process, it is necessary to avoid frequently opening the doors of the cold and hot impact box to avoid affecting the test results.

The correct maintenance method can extend the service life of the cold and hot impact box and ensure the accuracy of test results. Here are some maintenance methods for cold and hot impact boxes:

1. Regularly clean the interior and exterior of the cold and hot impact box. Use a clean cloth and cleaning agent to clean the box, and avoid using cleaning agents containing acidic or alkaline components.

2. Regularly check the temperature sensor and controller of the cold and hot shock box. If problems are found, they need to be replaced or repaired in a timely manner.

3. Regularly check the insulation performance of the cold and hot impact box. If a decrease in insulation performance is found, it is necessary to replace the insulation material in a timely manner.

4. Regularly replace the filter screen of the cold and hot impact box. The filter can prevent dust and impurities from entering the box, which can affect the test results.

5. Regularly maintain and maintain the cold and hot impact box. This includes inspecting and replacing parts, lubricating mechanical components, etc.

6. Avoid placing overweight or oversized electronic products in the cold and hot impact box to avoid damaging the testing room and testing frame.

Before using a cold and hot impact box, preheating and pre cooling treatment are required to ensure stable temperature in the testing room.

8. Avoid frequently opening the doors of the cold and hot impact box, and minimize the impact on the indoor temperature during the testing process.

9. Regularly calibrate the temperature sensors and controllers of the cold and hot shock box to ensure the accuracy of the test results.

The above is an introduction to the use and maintenance methods of cold and hot impact boxes. If you have any needs in this regard, please consult Chuangxin Testing! When maintaining the cold and hot shock box, it is necessary to regularly clean, inspect, and replace components to ensure the normal operation of the equipment. At the same time, it is necessary to follow the correct usage method to avoid affecting the test results.
