[0002] Ventilation aging test chamber is suitable for heat resistance test of electrical insulation materials, ventilation aging test of electronic parts and components, and plasticized products. It is used to assess their adaptability for storage and use in high temperature environment. After the samples are aged in air under simulated high temperature and atmospheric pressure environment, their performance is measured and compared with the performance of unaged samples.

[0003] When the existing experimental objects are implemented in the ventilation aging test chamber, they are directly placed on the placement table inside the ventilation aging test chamber and then heated at high temperature. Since the temperature of various parts inside the ventilation aging test chamber is inconsistent, the temperature borne by various parts of the experimental objects is inconsistent, resulting in inaccurate experimental data and affecting the accuracy of the experiment.
