Cold accumulating transportation box

Abstract

The invention relates to a cold accumulating transportation box, in particular to a box body structure capable of keeping the temperature of the inner part of the box body to be minus 60 DEG C or below. The box body structure comprises a box body, wherein a box cover is arranged on the box body; the box body adopts a four-layer structure sequentially comprising a first insulating plate, a first cold accumulating unit, a second insulating plate and a second cold accumulating unit; the top of the first insulating plate is movably connected with the box cover; sodium chloride salt eutectic is stuffed in the first cold accumulating unit; and lithium chloride salt eutectic is stuffed in the second cold accumulating unit. According to the cold accumulating transportation box disclosed by the invention, when own mass of the cold accumulating transportation box is maintained, the temperature of the inner part of the box body can be kept to be at minus 60 DEG C or below for a long time; and besides, the problem of refrigerated transport of articles which are temperature sensitive including frozen blood products and the like is solved at lower cost.

Description

technical field [0001] The invention relates to a cold storage transport box, in particular to a box body structure capable of keeping the temperature inside the box below -60°C. Background technique [0002] A refrigerated transport box is a common device in the transportation of agricultural products, seafood, and biological products. It can keep the items to be transported at a temperature below the ambient temperature, thereby maintaining their freshness or biological activity. The cold storage transport box is a kind of refrigerated transport box. It relies on the phase change of the cold storage material to provide cold energy to the items in the box. The common phase change temperatures are -16°C, -23°C, and -50°C. Some blood products, such as frozen red blood cells and frozen platelets, are very sensitive to temperature, and their biological activity will decrease rapidly when the storage temperature is higher than -60°C.

Problems solved by technology

However, for a given storage and refrigerated transportation task, that is, the effective space in the box is certain. Under the condition that the overall size and weight of the refrigerated transportation box are limited, the low temperature below -60°C cannot be achieved. Therefore, it is impossible to transport blood with this device. products
