Description

Technical Field

[0001] This utility model relates to the field of physical environment testing equipment technology, and more specifically, to a testing cavity that can realize multiple physical environments. Background Technology

[0002] Physical environment testing is often used to simulate the operating status and parameters of equipment under simulated physical environments. This simulates the equipment's performance under normal and extreme physical conditions, allowing for equipment optimization and improvement. Common physical environment tests include temperature and humidity tests, salt spray tests, spray tests, sunlight tests, special gas circulation and concentration tests, humidity monitoring, and computer control. The test chambers used are generally made of stainless steel, which is inexpensive to manufacture and meets most testing requirements. However, for environmental tests requiring radiation emission, the currently used stainless steel test chambers significantly interfere with the radiation and emission environment, affecting the accuracy of the tests. This invention proposes a new solution to address these issues. Utility Model Content

The test chamber comprises an inner cavity, a thermal insulation layer, an outer cavity, UV lamps, a temperature and humidity sensor, an air inlet pipe, and an exhaust pipe. Both the inner and outer cavities are integrally formed from fiberglass panels, forming an installation cavity between them. The thermal insulation layer is disposed within the installation cavity. The UV lamps are arrayed and mounted on the outer side of the inner cavity. The temperature and humidity sensor is mounted on the inner side of the inner cavity. The output end of the air inlet pipe and the input end of the exhaust pipe pass through the outer cavity, the thermal insulation layer, and the inner cavity, communicating with the inner side of the inner cavity.

[0006] Preferably, the front end face of the test chamber is provided with a pick-up and drop-off port, and a sealed cabinet door is rotatably connected to the pick-up and drop-off port via a hinge.
