Future Trends and Developments in Rapid Temperature Change Test Chamber Technology

Rapid temperature change test chamber:

Suitable for aerospace, information electronics, instrumentation, materials, electrical, electronic products, and various vital parts to judge whether parameters such as reliability, machine stability, and performance are qualified in high and low temperature or humid heat environments, and will be provided to The basis for you to predict and improve product quality and reliability.

The rapid temperature change test chamber is divided into three parts: high temperature area, low temperature area and test area. It adopts the original Japanese Youyi control brand temperature instrument, Chinese and English display control system; it has a fully automatic and high-precision system. Any part of the movement is completely controlled by P.L.C. Locking processing; automatic circuit and warning signal when the parts fail; emergency stop device when the input voltage is unstable.

The heating and cooling humidification system of the test chamber is independent, which can improve efficiency, reduce test cost, increase life, and reduce failure rate; the cold machine adopts French Taikang fully enclosed compressor unit, and its refrigeration system adopts unit or binary low temperature Loop system design; its multi-wing blower has strong air circulation, which can avoid any dead angle and make the temperature and humidity distribution in the test area even.

The rapid temperature change test chamber is mainly used to simulate the testing of electronic components under high and low temperature or main humid and hot natural environment conditions; the electrical components of the test chamber mainly include: heating system, refrigeration system and control system.

The characteristics of the rapid temperature change test chamber:|

a. Intelligent control system: Automatically start the large compressor to cool down when the temperature is rapidly cooled, and the high temperature and temperature rise process is linearly controlled by the balance temperature of the small compressor to save energy;
b. Energy-saving, carbon-reducing and power-saving design, rapid temperature change test chamber stability and energy-saving effect, can save more than 30% year-on-year;

c. The controller operation adopts the new fuzzy algorithm technology to control and automatically adjust the cold coal flow, effectively taking away the heat load of the tested product to achieve the control effect;
d. The rapid temperature change test chamber can set different stress screening temperature change rates of 5°C/min, 10°C/min, 15°C/min, 20°C/min;

e. It can perform various tests such as rapid temperature change (stress screening), condensation test, high temperature and high humidity, temperature and humidity cycle;
f. Meet the requirements of stress screening test for electronic equipment products;

Scientific design of rapid temperature change test chamber:

The rapid temperature change test chamber imports “program controller, color liquid crystal display touch screen, imported refrigerator, digital display, etc., and is equipped with micro-printer, new technology of energy regulation, and has many functions such as over-temperature, over-pressure, compressor overheating and power shortage. a protective function.

The high-strength and high-reliability structural design of the rapid temperature change test chamber ensures the high reliability of the equipment; the material of the studio is “SUS304 stainless steel anti-corrosion” to achieve a long service life, and the surface spray treatment is to ensure the “long-lasting” of the equipment Anti-corrosion function and appearance life”; high-strength and temperature-resistant silicone rubber sealing strip ensures the high sealing of the door of the test chamber equipment; a variety of optional functions can ensure the needs of users for various functional tests.

The air duct of the rapid temperature change test chamber is located at the rear of the working room, and the heater, cooling evaporator fan blade and other devices are distributed in the interlayer of the air duct. This test chamber uses multiple fans to circulate the air in the chamber, and when the fan rotates at a high speed, the air in the working room is sucked into the air duct from the bottom, and blown out from the top of the air duct after heating/cooling, and the air in the working room is exchanged with the sample. The air is then sucked into the air duct, so it circulates repeatedly to achieve the temperature setting requirement.

How to choose a rapid temperature change test chamber?

To buy a rapid temperature change test chamber, you must know its purpose and quality, and the test chamber is suitable for aerospace products, information electronic instruments, materials, electronic and electrical products, and various electronic components under the condition of rapid temperature changes Check the various performance indicators of the product; this is the purpose we must know.

The next step is to understand its temperature and quality. There are several options for the temperature of Linpin’s rapid temperature change test chamber (A: -20℃～150℃ B: -40℃～150℃ C: -60℃～150℃ ℃), so you need to buy according to your own needs when choosing.

Then there is the quality of this test chamber. In fact, users who choose Lisun test chamber don’t have to worry about this, because about 90% of each Linpin equipment uses imported spare parts, such as important controllers. , which adopts the temperature instrument of “UYICON” brand imported from Japan, and the compressor is used for French Taikang (Germany Bitzer)

Finally, find out whether the required rapid temperature change test chamber can meet the demand. If it can meet the demand, then consult whether the manufacturer has after-sales service (in the future, if the equipment fails, it can be repaired in time), so that you can know that it belongs to the manufacturer, but We cannot rule out that it is the manufacturer, so a site visit is required.

If you want to be simple, don’t ask whether there is after-sales service, but just ask if you can conduct an inspection. If you say yes, it can prove that the manufacturer has after-sales service. From it, we can see the workmanship of the rapid temperature change test chamber and how to treat the details.

As mentioned above, the rapid temperature change test chamber has been on the rise. This is because technology has become more and more developed, which makes people more and more pursuing perfect items. And the test chamber is constantly pursuing a higher level with the loss of time. Although the current equipment can be regarded as a perfect handicraft compared with the past, if it stops and does not look forward, then the equipment will be eliminated. It’s a big loss for a product that needs to be inspected, so the environmental equipment will evolve even better over time.

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.
