Description

Portable refrigerator and refrigeration equipment

Technical Field

The invention relates to the technical field of refrigeration, in particular to a portable refrigerating box and refrigerating equipment.

Background

Generally, some newly collected environmental samples, analysis samples, chemical reagents, preparations, biological samples, etc. need to be stored at a relatively low temperature and transported to a corresponding place for detection or use.

In order to avoid the failure of effective components in a sample to be detected, people need to refrigerate the sample and then transport the sample.

However, this prior art has the following drawbacks: the surface of the ice block is smooth, the container containing the sample to be detected is in contact with a smooth ice surface, and mutual collision is easy to occur between the container and the container in the transportation process, so that the sample to be detected in different containers is spilled, and even more, the mutual collision between the containers is serious, so that the sample is completely overflowed, and finally the sample cannot be used and is wasted; when the installation groove needs to be formed in the ice block, the surface of the ice block is hard, and the regular groove is difficult to form, so that even if the groove is formed, the inner surface of the groove is difficult to match with the outer surface of the container provided with the sample, and when the regular groove needs to be formed, a specific tool is needed to form, so that the production cost is increased. Therefore, the refrigeration device in the prior art has the technical problems of easy sample waste and high production cost.
