Optimization and improvement of ensuring temperature uniformity in the cold and hot shock test chamber

Box wall heat conduction

• Optimize the heat conduction of the box wallEnsure smooth heat conduction of the box wall, reduce heat loss such as high temperature box leakage or low temperature box leakage, lower the temperature difference of the supply air, and make the supply air temperature of the high temperature box closer to the working temperature inside the box, and the supply air temperature of the low temperature box closer to the temperature inside the box, thereby reducing the possibility of temperature unevenness inside the test box. one

Heat transfer coefficient of box wall

• Balance box wall heat transfer coefficientMake the heat transfer coefficients of the six sides of the box wall as equal as possible, reduce the uneven temperature of the box wall caused by local uneven heat transfer, and thereby reduce the impact on radiative convection heat transfer inside the box, ensuring uniform temperature inside the test box. one

Placement of test samples

• Reasonably place test samplesAvoid placing too many test samples in the studio that affect the overall internal heat convection, especially samples that generate heat themselves, such as LED lighting products, to reduce the impact on the internal temperature uniformity. one

Test box structure

• Optimize the structure of the test chamberTry to make the structure of the test chamber symmetrical and reduce the influence of structural factors on the temperature uniformity of the working room. one

Air duct system

• Optimize the air duct systemEnsure that the air duct system can evenly deliver cold and hot air to various positions inside the test chamber, improving the uniformity of temperature distribution.

control system

• Accurate control systemBy adopting advanced control systems, temperature can be adjusted more accurately, respond to temperature changes in a timely manner, and ensure temperature stability and uniformity.
