[0031] Sound-absorbing cotton 5 is applied to the inner wall of the enclosure 4. The sound-absorbing cotton 5 is used to absorb the noise generated by the equipment during operation.

[0032] In this embodiment, a test chamber 2 and a refrigeration system 3 are installed on the frame 1 to simulate an environmental test chamber where the product experiences extreme temperature changes in a short period of time. The refrigeration system 3 is used to quickly reduce the temperature inside the test chamber 2 from high to low temperature in a short period of time, rapidly absorbing heat inside the chamber to ensure the normal operation of the test chamber equipment. Enclosures 4 are installed on the frame 1, including movable doors, enclosure panels, and covers on the equipment. Sound-absorbing cotton 5 is applied to the inside of each enclosure 4 to absorb the noise generated by the equipment and reduce the harm of equipment noise to workers and the working environment.
