Insulation box

Abstract

The invention discloses an insulation case. Wall plates of the insulation case are insulation plates which comprise outer plates, inner plate components and insulation layers. Each inner plate component comprises a plurality of packaging unit which are connected into a plate shape. Each packaging unit comprises a hollow structure with a cavity. Each inner plate component comprises a plurality of phase-change energy-storage units which are accommodated in the cavities. The insulation layers are arranged in the middle of the outer plates and the inner plate components. By means of the insulation case, the cavities are formed in the packaging units included in the inner plate components, so that the phase-change energy-storage units can be accommodated in the cavities, space in the insulation case is saved, the phase-change energy-storage units in the inner plate components and goods in the insulation case are almost not isolated, and accordingly, the temperature of goods in the case can be controlled accurately by the phase-change energy-storage units, and the stability is high.

Description

technical field [0001] The invention relates to an insulated box body. Background technique [0002] There are two main types of incubators at present, one is an ordinary incubator, which generally uses the specific heat of the goods in the box itself combined with the heat preservation of the box to meet the temperature requirements for the transported goods. However, this type of incubator will generally change with the temperature outside the box, and the temperature of the goods in the box will also change slowly, and the temperature difference between the inside and outside of the box during transportation should not be too large, otherwise it may cause deterioration or damage to the goods Wait. [0003] Another kind of incubator adopts the method of accommodating phase-change energy storage materials therein. The incubator in the prior art generally installs the phase change energy storage material in the incubator or pre-buries it in the foam layer, but the former g...

AI Technical Summary

Problems solved by technology

The incubator in the prior art generally installs the phase change energy storage material in the incubator or pre-buries it in the foam layer, but the former generally takes up more space in the box and affects the height of the box. Since the phase change energy storage materials cannot be evenly distributed in the incubator, it may cause a large temperature difference between different positions in the box, which is not conducive to the storage and transportation of goods

However, if the phase change energy storage material is pre-embedded in the foam layer, there will be multiple thermal resistances between it and the goods, so that the phase change energy storage material cannot accurately control the temperature of the goods in the box, and the phase change energy storage material will not be able to accurately control the temperature of the goods in the box. It cannot be replaced after being buried in the foam layer, and has a single purpose, which is not conducive to cost saving
