Description

Technical Field

[0001] The utility model relates to the field of test chambers, in particular to an environmental test chamber. Background Art

[0002] Environmental testing chambers are a general term for all test chambers that simulate natural climates and are used to test the performance of products or materials under different environmental conditions. They simulate various climatic conditions, such as high and low temperatures, and humidity fluctuations, to evaluate the durability and performance of products or materials under these conditions. These devices are widely used in products such as electronic components, automotive parts, and laptops to ensure that they function properly in their intended environments. Existing temperature environmental testing chambers retain a significant amount of residual heat after heating tests. This heat is directly lost, resulting in energy waste. Utility Model Content
