Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a cold insulation and heat preservation device. Background Technology

[0002] In the field of biological samples, samples need to be preserved at low temperatures for a long time. Therefore, the sample storage area needs to maintain a low temperature for a long time. When samples enter or leave the storage area, the storage area will be opened to allow the samples to enter and leave. During this process, heat exchange will occur due to the temperature difference between the inside and outside, causing temperature fluctuations in the low-temperature storage area. The sealed doors used in the existing technology have a large opening area, which is not conducive to heat preservation. Although the roller shutter door has a smaller flow area, it cannot be closed all the time and consumes more energy. Utility Model Content

Simultaneously, it avoids temperature fluctuations in low-temperature areas, ensuring sample safety. Attached Figure Description

When sample storage and retrieval are not required, the sealing door 41, located behind the roller shutter 31, completely closes off internal and external flow. During sample entry and exit, the sealing door moves horizontally, and the lifting component 21 moves the storage and retrieval assembly 22 and the storage and retrieval channel 32 vertically. The upper roller 33 and lower roller 34 at both ends of the roller shutter 31 work together to raise and lower the roller shutter, moving the storage and retrieval channel 32 to the target position. The storage and retrieval assembly 22 then enters and exits the storage and retrieval channel 32 to complete the sample storage and retrieval operation. By setting up two cooling structures—the sealing door 41 and the roller shutter 31—only a small portion of the storage and retrieval channel 32 allows for internal and external flow during storage and retrieval, minimizing temperature exchange and energy consumption. This also prevents temperature fluctuations in low-temperature areas, ensuring sample safety.
