The rapid temperature change test is used to determine the adaptability of products in storage, transportation and use in climates with rapid or slow changes in high-low temperatures. The test process is a cycle of normal temperature → low temperature → low temperature dwell → high temperature → high temperature dwell → normal temperature. The severity of the temperature cycling test is determined by the high/low temperature range, dwell time and number of cycles.
The stress screening of the rapid temperature change Test Chamber is to use the temperature acceleration technology (the product will alternately expand and contract when working in the upper and lower limit temperatures) to change the external environmental stress under the design strength limit of the product, so that the product produces thermal stress and strain, through acceleration Stress makes potential defects in the product (potential component material defects, assembly defects, process defects) appear, avoiding the failure of the product when it is subjected to environmental stress during use, causing unnecessary losses, and improving product quality and reducing maintenance times have a significant impact.
Suitable for safety performance testing of electronic life components, providing reliability testing, product screening testing, etc. The rapid temperature change test is a necessary test in the fields of aviation, automobiles, home appliances, scientific research, etc., and determines the adaptability of parameters and performance of electrical, electronic, automotive electrical appliances, materials and other products after the temperature environment changes. It is suitable for schools, factories, Military industry, scientific research posts and other units. As one of the manufacturers of temperature and humidity Test Chambers, Yuanyao provides high-quality rapid temperature change Test Chambers.
The rapid temperature change Test Chamber is mainly divided into linear rapid temperature change and nonlinear rapid temperature change. The differences between them are as follows:
Linearity means that there is a linear functional relationship between temperature and time, that is, there is a linear relationship between them. If the temperature rise and fall rate of the custom-made rapid temperature change Test Chamber can reach 3°C/min, after setting the corresponding rate on the controller, the temperature rise or fall will change according to the set rate every increase of 1 minute. Its heating rate and cooling rate are fixed per minute, and the fastest can reach 3°C/min.
Non-linearity refers to the average temperature change during the time period when the set temperature is reached during the entire temperature rise and fall. It refers to the increase or decrease in temperature by a few degrees per minute over a period of time. It is controlled by the heating system and cooling system PID of the equipment itself.
