Description

Technical Field

[0001] The utility model relates to the field of constant temperature and humidity chambers, in particular to an inner partition structure of a constant temperature and humidity chamber. Background Art

[0002] Constant temperature and humidity chambers are environmental testing equipment widely used in scientific research, industrial production, medicine, and healthcare. They simulate specific temperature and humidity conditions to conduct performance testing and quality inspections on items or materials. Many industries place extremely high demands on the stability and uniformity of the test environment's temperature and humidity. For example, in reliability testing of electronic components, even slight fluctuations in temperature or humidity can lead to deviations in test results, thus affecting product quality assessments. In the biopharmaceutical field, cell culture and drug stability studies also require precisely controlled constant temperature and humidity environments.

[0003] Conventional constant temperature and humidity chambers typically utilize internal partitions made of a single material, which have limited thermal and moisture insulation properties. This can easily lead to temperature and humidity fluctuations within the chamber, affecting the accuracy of test results. Furthermore, improperly designed internal partitions can result in poor airflow and uneven temperature and humidity distribution within the chamber. Utility Model Content

The multi-layer composite panels include, from the outside to the inside, a stainless steel outer layer, a heat insulation layer, and a moisture-proof layer. Multiple conveying grooves are horizontally opened between the heat insulation layer and the moisture-proof layer in the top and bottom multi-layer composite panels of the inner compartment box. Multiple connecting holes connected to the conveying grooves are opened on one side of the moisture-proof layer and the stainless steel outer layer.

[0007] Preferably, a plurality of connecting pipes are fixedly provided at one end of the stainless steel outer layer, and one end of the connecting pipe is connected to one end of the conveying trough.
