Description

[0002] A cold box is a device used to maintain low temperature or refrigerate food, medicine or other items. It is usually designed with a heat insulation layer and a sealed structure, which can effectively prevent heat conduction and the entry of external heat, so as to maintain a low temperature environment inside. Cold boxes are widely used in households, commercial places and medical institutions, and can ensure the freshness and safety of food and medicine. Some cold boxes are also equipped with refrigeration systems, such as compressors or adsorbents, so as to maintain low temperature without external power supply.

[0003] When replacing the adsorbent inside the traditional cold box adsorber, the cover door of the adsorbent is directly opened by tools, and the adsorbent inside is directly taken out and replaced. Therefore, a large amount of cold air will be lost during the replacement. When the adsorbent is replaced, the temperature inside the cold box may rise, resulting in the cold box being unable to maintain an ideal low temperature state during the replacement process, which will affect the overall refrigeration efficiency of the cold box.
