Flexible cold accumulation plate

Abstract

A flexible cold accumulation plate comprises two cold accumulation layers, wherein the two cold accumulation layer are arranged side by side and separated from each other; each cold accumulation layer comprises an outer side outer film and an inner side outer film, the outer side outer film is in welded connection with the inner side outer film through heat-seal lines formed through hot pressing, and a plurality of mutually separated fluid reservoirs filled with a cold accumulation agent are arranged between the heat-seal lines. The outer side outer film and the inner side outer film of the flexible cold accumulation plate are flexible plastic films, thereby being excellent in deformation, can be bent during the use, and can be adhered to the surface of an object to be surrounded, therefore, cold transmission evenness is improved, temperature at all parts of an object to be surrounded is kept to be uniform as far as possible, due to the arrangement of the two cold accumulation layers, uneven cold accumulation agent caused by squeezing during the use can be avoided, and further the cold storage capability of the cold accumulation plate is further improved, therefore, a relatively good cold accumulation effect is obtained, and the effect of keeping cold for a long time is played.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics, in particular to a flexible cold storage plate. Background technique [0002] Coolant is usually a viscous jelly mixture composed of organic or inorganic compounds, which can absorb and store a large amount of cold energy at low temperatures, and release a large amount of cold energy when the temperature is high, so that it can maintain itself for a long time. Low temperature environment in a small range around. [0003] The main problem in the field of cold chain transportation such as food, medicine and vaccines is the broken chain of the cold chain link. Food and medicine are pre-cooled at the place of origin and loaded into the transport vehicle to reach the wholesale market at the place of sale, and finally enter the retail link for storage. Both are prone to cold chain breaks. The use of cooling agents can effectively solve the problems encountered in the pre-cooling from the...

Problems solved by technology

[0004] The cold storage agent is usually packaged in the cold storage plate for use. The cold storage plate in the prior art is designed as a rectangular parallelepiped plate structure. According to the specific use, the cold storage plate is processed into various volumes, but the existing The cold storage plate in the technology is generally thick, which makes it inconvenient to use

When used in conjunction with the transport box, the traditional cold storage plate can only be placed on the surface and surroundings of the transported object, resulting in uneven transmission of cold energy in the box. When the placement is irregular, the above disadvantages are more obvious

In addition, traditional cold storage plates are only suitable for transportation in cold chain logistics and cannot be used in daily life, that is, ordinary consumers cannot touch and use them.
