[0002] In the fields of biomedicine, environmental monitoring, and drug transportation, constant temperature refrigerators are a common device used to keep samples under specific temperature conditions. Traditional refrigerator designs often ignore the effective management of internal items and the accuracy of temperature control, which results in large temperature errors that cannot be better maintained within the specified value deviation range, resulting in poor use effects. In particular, when transporting items that need to maintain a constant temperature environment for a long time, such as long-distance transportation or long-term storage, the use of ice packs as refrigerants becomes particularly important. However, ice packs are generally stacked directly inside the refrigerator, and they need to be taken out manually one by one, which may squeeze the samples, causing damage to the refrigerated samples and affecting the use effect.
