Working principle of the Temperature shock test chamber and Thermal cycle chamber

The high and low temperature humidity test chamber, also known as the temperature shock test chamber and the thermal cycle chamber, is a device used to test the performance of products under high temperature, low temperature, and humidity environments. It is widely used in industries such as electronics, electrical appliances, automation instruments, aerospace, and automotive.

The high and low temperature humidity test chamber has the characteristics of high reliability, good stability, and simple operation. It can simulate the temperature and humidity changes in real environments to evaluate the tolerance and reliability of products by observing their performance under different conditions.

In the high temperature test, the test chamber will set the temperature to a range higher than the normal operating temperature of the product and maintain it for a period of time. This can test whether the product will overheat, short circuit, deform, etc., and its ability to withstand high temperatures. High temperature testing can help product designers determine the maximum operating temperature range of the product and eliminate potential failures that may occur at high temperatures.

In the low temperature test, the test chamber will set the temperature to a lower range and maintain it for a period of time. This can test whether the product will have cooling problems, embrittlement, deformation, etc., and its ability to tolerate low temperatures. Low-temperature testing can help product designers determine the minimum operating temperature range of the product and eliminate potential failures that may occur at low temperatures.

In the humidity test, the test chamber will adjust the temperature and humidity to a higher range simultaneously and maintain it for a period of time. This can test whether the product will corrode, detach, leak electricity, etc., and its tolerance in a humid and hot environment. Humidity testing can help product designers determine the reliability of the product in high humidity environments and eliminate potential failures that may occur in such conditions.

The high and low temperature and humidity test chamber can simulate various actual working environments, such as extremely cold regions, desert areas, and humid environments. It can help product designers discover potential issues and make necessary improvements during the product development process. By testing products in the test chamber, potential problems that may occur in different environments can be identified in advance, ensuring product quality and reliability.

The working principle of the high and low temperature and humidity test chamber is to generate high temperature, low temperature, and humidity environments through electric heaters and humidifiers. The test chamber is equipped with temperature controllers and humidity controllers. By accurately adjusting the parameters of the controllers, precise control of the temperature and humidity inside the test chamber can be achieved. Additionally, the test chamber is equipped with fans and temperature sensors to ensure even distribution of temperature and humidity inside the chamber.

During high and low temperature and humidity testing, specific settings are made based on the requirements and standards of the product. First, the required temperature range and rate of change are determined. Then, the product is placed inside the test chamber, and the desired temperature and humidity parameters are set. During the testing process, the temperature and humidity are gradually changed to the set values and maintained for a period of time. After the testing is completed, the performance of the product is observed, and its performance indicators are measured to assess its reliability and tolerance in different environments.

The high and low temperature and humidity test chamber can be used not only in the research and development and production processes of products but also in quality control and inspection. By subjecting products to high and low temperature and humidity testing, non-conforming products can be identified, potential problems can be detected and resolved timely, and the quality and reliability of the product can be improved.

In conclusion, the high and low temperature and humidity test chamber is a crucial testing equipment that helps product designers evaluate the performance and reliability of products in different environments. Its wide application has significant importance in enhancing product quality and reliability .

In the future, with the continuous development of technology, the functionality and performance of the high and low temperature and humidity test chamber will continue to improve, providing more accurate, reliable, and effective testing methods for product design and manufacturing.

Precautions for using the high and low temperature test chamber:
1. Do not open the test chamber door while the equipment is operating. Opening it during high temperatures may cause burns to the operator, and opening it during extremely low temperatures may cause early frostbite to the personnel and may lead to the freezing of the air conditioning evaporator, affecting the cooling effect. If it is necessary to open, please take necessary safety precautions.

2. During the operation of the high and low temperature test chamber, the cover of the switch power supply wiring terminal must be installed inside the terminal board for safe use of electricity.
3. To avoid common faults of the high and low temperature test chamber, please provide a switch power supply within the rated current range.
4. The ventilation port should be kept clear to prevent common faults, abnormal operations, shortened service life, and fire accidents.
5. It is strictly prohibited to dismantle, process, modify, or repair the high and low temperature alternation test chamber. Otherwise, there is a risk of abnormal operation, electric shock accidents, and fire accidents.
6. The wiring must be correct and the grounding device must be in place. Failure to ground the device properly can lead to electric shock accidents, incorrect operation safety accidents, abnormal displays, or inaccurate
measurements.
7. During the installation of the equipment, ensure that no dust, wire knots, iron pins, or other objects enter, as this may cause misoperation or common faults.
8. If the equipment is found to be damaged or deformed during unpacking, do not use it.
9. To prevent electric shock accidents, misoperation, and common faults, do not turn on the switch power supply before the installation and wiring are completed.
10. When operating the high and low temperature test chamber during operation, changing settings, data signal output, start, stop, etc., the safety factor must be fully considered. Incorrect operations can damage the equipment or cause common faults.
11. Clean the high and low temperature test chamber with a damp cloth. Do not use ethanol, automobile gasoline, or other solvents, and do not splash water onto the high and low temperature test chamber. If the high and low temperature test chamber comes into contact with water, please immediately stop using it, as there is a risk of electric shock, electrocution, or fire.
12. Regularly maintain the terminal screw and fixing bracket. Be cautious of any looseness.
