The split structure is designed to separate the test area from the refrigeration system, which not only facilitates moving in and out of the laboratory, but also fully meets the high test requirements. When a test needs to ensure that there is no vibration in the area when the test sample is tested under various environmental conditions, and the compressor and condenser are the main vibration sources of the temperature box. The use of a split type to connect the copper tube with the refrigeration device can keep the compressor and the condensing fan away from the test area, effectively avoiding the generation of vibration transmission.
