Innovative Features and Applications of Rapid Temperature Change Test Chamber

Rapid temperature change test chamber: it is suitable for cold resistance test of electrical and electronic products and parts, adaptability test under rapid temperature change or gradual change conditions, so it is especially suitable for Environmental stress screening (ESS) test of electrical and electronic products.

The rapid temperature change test chamber is mainly designed for the adaptability testing of electrical and electronic products, as well as other raw materials for storage, transportation, and use in high-temperature and low-temperature rapidly changing environments.

The rapid temperature change test chamber utilizes temperature acceleration techniques to change the external environmental stress (alternating expansion and contraction of the product during cycling within the upper and lower limit temperatures) under mild design limits, and then allows latent defects in the product to surface on the surface of the part material, process defects, and process through accelerated stress,

In order to avoid unnecessary losses caused by product failure during use due to environmental stress, it is beneficial to improve product shipment and reduce the number of repairs.

The characteristics of the rapid temperature change test chamber are:
a. Intelligent control system: Automatically start the large compressor to cool down during rapid cooling, and the high temperature and heating process are linearly controlled by balancing the temperature of the small compressor to achieve energy conservation;

b. Energy saving, carbon reducing, and electricity saving design, stable and energy-saving performance of the rapid temperature change test chamber, which can save more than 30% year-on-year;
c. The controller adopts new fuzzy algorithm technology to automatically adjust the cold coal flow rate, effectively removing the heating load of the tested object to achieve control effect;

d. The rapid temperature change test chamber can set different stress screening temperature change rates of 5 ℃/min, 10 ℃/min, 15 ℃/min, and 20 ℃/min;
e. Can perform various tests such as rapid temperature change (stress screening), condensation test, high temperature and humidity, temperature and humidity cycling, etc;
f. Meet the requirements of stress screening tests for electronic equipment products;

The purpose of the rapid temperature change test chamber is:
Rapid temperature change test chamber: mainly used for environmental simulation testing of the physical and other related characteristics of products under low and high temperature conditions according to national standards or user defined requirements. The results of the testing are used to determine the performance of the product and whether it meets the requirements for product design, improvement, identification, and factory inspection.

Due to the rapid temperature change test chamber: mainly composed of a chamber body, refrigeration system, heating system, air circulation system, and control system, the outer shell of the box body is made of “cold rolled steel plate electric spray molding” (users can choose high-quality stainless steel plate);

The inner liner is made of high-quality stainless steel plate; A “large area observation window” is installed in the middle of the chamber door and equipped with an observation light, allowing users to clearly see the condition of the sample and the overall appearance is beautiful and elegant.

The insulation layer of this test chamber is “hard polyurethane foam with a small amount of ultrafine glass wool”, so it needs to have high strength and good insulation performance.

Rapid temperature change test chamber: The main temperature control instrument adopts (intelligent digital temperature and humidity control instrument), and the humanized design of the operation method is easy to learn and use. Due to the compatibility of instrument operations of different functional levels, it is necessary to be compatible with each other; For input, a digital calibration system is used, as well as built-in commonly used thermocouples and thermal resistance nonlinear correction tables, to ensure accurate and stable measurement;

And it has AI artificial intelligence adjustment function, 0.2 level accuracy, and multiple alarm modes; And the refrigeration system adopts a fully enclosed imported compressor unit, which has a mechanical single stage refrigeration or overlapping low-temperature circuit system, and can fully automatically control and coordinate safety protection system; And the heating of the machine adopts stainless steel finned heating tubes.

The rapid temperature change & humidity heat test chamber is a temperature and humidity test device, applied for aerospace products, information electronic instruments, electrical, electronic products, and various electronic components to test various products under the condition of rapid temperature change performance.
