Foldable phase-change energy-storing cold chain refrigerator

Abstract

The invention relates to a foldable phase-change energy-storing cold chain refrigerator, comprising a foldable packing outer box and a foldable insulating inner box, wherein the foldable insulating inner box is made by an insulating plate which is internally and externally attached with aluminium films; in order to improve the time of refrigerating and insulating, a foam insulating side plate block, a foam insulating bottom plate block and a foam insulating top plate block are respectively arranged between the foldable packing outer box and the foldable insulating inner box; and the foldable insulating inner box is internally provided with a foldable insulating ring sleeve which is made by the insulating plate which is internally and externally attached with aluminium films. The foldable insulating ring sleeve is internally provided with a phase-change energy-storing bag or a phase-change energy-storing box meeting the requirements of phase-change temperature and refrigerating temperature. The foldable phase-change energy-storing cold chain refrigerator has low cost, compressible folding, and convenient transportation and recovery, and can meet the requirements of different cold chain refrigerating transportation time and refrigerating and insulating due to the arrangement of the foam insulating side plate block, the foam insulating bottom plate block, the foam insulating top plate block, the foldable insulating ring sleeve, the phase-change energy-storing bag and the phase-change energy-storing box.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics packaging and refrigeration, and relates to a foldable phase change energy storage cold chain refrigerator. Background technique [0002] At present, with the development of society, the market demand for refrigerated chain transportation is increasing. The fields involved are very wide: including food, medicine, biotechnology products, electronic components, industrial adhesives, paints, etc. [0003] The traditional cold storage refrigerated transportation uses dry ice, but there are obvious problems with the use of dry ice, because dry ice will be converted into gaseous carbon dioxide at minus 70 degrees Celsius, and gaseous carbon dioxide is a dangerous and harmful substance. , especially air and rail transport will be subject to special regulations for safe transport.

AI Technical Summary

Problems solved by technology

[0003] The traditional cold storage refrigerated transportation uses dry ice, but there are obvious problems with the use of dry ice, because dry ice will be converted into gaseous carbon dioxide at minus 70 degrees Celsius, and gaseous carbon dioxide is a dangerous and harmful substance. , especially air and rail transport will be subject to special regulations for safe transport

[0004] Ordinary transport incubators are mostly made of foam plastic or aluminum-plastic composite gold material, with a foam insulation layer inside and a handle. The disadvantages are: large volume, heavy weight, cannot be folded, high production cost, not suitable for refrigeration Logistics transportation, especially cold chain express delivery; if it is used as a refrigerated and insulated transport box, the weight will cause the packaging cost to be too high during purchase and transportation, and it is inconvenient to recycle and transport, and it is difficult to promote and use it in a large area; people need a low-cost, Lightweight, foldable, easy to transport, easy to recycle, recyclable, can be suitable for different refrigerated transportation time and different refrigerated temperature requirements of the collapsible phase change energy storage cold chain refrigerator
