Heat preservation box

Abstract

The invention discloses a heat preservation box. The heat preservation box comprises an inner box and an outer box containing the inner box, the inner box is provided with an inner box body with a first opening and a first cover which operably covers the first opening, the inner box body is provided with a first base and two pairs of relative first side plates connected to the first base in a foldable mode, the outer box is provided with an outer box body with a second opening and a second cover which operably covers the second opening, and the outer box body is provided with a second base and two pairs of relative second side plates connected to the second base in a foldable mode. Compared with the prior art, the heat preservation effect is good, and the heat preservation time is long.

Description

technical field [0001] The embodiment of the present invention relates to a container, in particular to an incubator. Background technique [0002] Existing thermal insulation containers are generally made of EPS and EPP foam materials, which have good toughness and poor rigidity. When using, put the goods in the container, then put the lid on the box body, and then distribute it. Like this kind of insulated box, the general outer size is 600*400*300mm, and the inner volume is about 45 liters. This kind of insulated container is mainly used For fresh food distribution, after sorting the pre-cooled fresh or frozen products in the cold storage, they are loaded into the incubator together with the cold storage plate, and then delivered to the household. This kind of thermal insulation container is a single box body. Since the thermal insulation performance of the thermal insulation container depends on the thermal insulation coefficient of the material itself and the thickness...

AI Technical Summary

Problems solved by technology

This kind of thermal insulation container is a single box body. Since the thermal insulation performance of the thermal insulation container depends on the thermal insulation coefficient of the material itself and the thickness of the box body, and the box body often needs to consider the use volume, so the thickness of the box body is relatively fixed when the thermal insulation coefficient is constant. , the final insulation performance is poor

The consumption of the cooling capacity by the ambient temperature outside the thermal insulation container causes the temperature inside the thermal insulation container to drop slowly, and the thermal insulation time is also short

The temperature in the incubator cannot be lowered to a very low temperature, so it cannot meet the needs of objects that need to be stored at a very low temperature

In addition, the heat preservation time is also short, and the heat preservation performance is poor, which makes it impossible to store and transport objects for a long time, and the use is relatively limited
