Cold-chain logistics heat preservation box and preparation method thereof

Abstract

The invention discloses a cold chain logistics incubator and a preparation method thereof. The incubator includes an outer box, a middle box and an inner box nested sequentially from outside to inside, the outer box includes an outer box body and an outer box cover, and the outer box body Both the inner box and the outer box cover are made of corrugated board structure; the middle box includes the middle box body and the middle box cover, and the middle box body and the middle box cover are both made of vacuum insulation board structure; the inner box includes the inner box body and the inner box cover, the inner box body and the inner box cover. The inner box cover adopts the cold storage plate structure, and the cold storage liquid is arranged in the cold storage plate. The heat preservation box has the advantages of simple structure, convenient use, low cost, high effective volume ratio and long heat preservation time. The preparation method of the cold chain logistics incubator has the advantages of simple process and high degree of standardization.

Description

technical field [0001] The invention relates to an incubator, in particular to an incubator with a high volume ratio for cold chain logistics, and a preparation method for the incubator. Background technique [0002] In the cold chain logistics industry, for items with special requirements on the temperature environment, the incubator is an indispensable tool. According to the different temperature requirements of the transported items, the incubator can keep its internal temperature relatively stable within a certain range and time, and it plays an important role in the cold chain logistics distribution industry such as medicine and fresh food. Insulation boxes are mainly divided into two types: active cooling and passive cooling. Among them, the passive cooling type has been widely used because it does not need to use a power source, has the advantages of convenient use, portable transportation, and wide application. However, the existing passive refrigeration type incuba...

AI Technical Summary

Problems solved by technology

However, the existing passive cooling incubators mainly use polyurethane, polystyrene and other materials as the insulation layer, resulting in a short insulation time, and the effective volume of the incubator is reduced due to the thick wall of the box body.

In addition, the box prepared by injection molding of plastic materials such as polyethylene and polypropylene has a relatively complex structure, high cost, and heavy weight, and its rigidity mainly depends on the support of the box structure, which is easy to cause deformation and affect the service life.
