Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation boxes, in particular to a lightweight dry ice thermal insulation box. Background Art

[0002] Dry ice is solid carbon dioxide, a white crystal. It sublimates easily at room temperature and has a high heat of vaporization. When it sublimates at normal pressure, it can rapidly reduce the surrounding temperature. Therefore, when dry ice sublimates in the air, it will liquefy and even further condense water vapor in the air. The formed water vapor droplets or small ice crystals adhere to the dust in the air to form the white smoke we can see. Dry ice needs to be insulated during transportation after production to prevent it from sublimating. Traditional insulated boxes are bulky. In order to better insulate and transport dry ice, a lightweight dry ice insulated box is proposed.

[0003] For example, the authorization publication number CN219668846U discloses an insulated box that facilitates identification of finished products inside, comprising a box body and a box lid for covering the box body, the box lid being hinged to the box body, the box body being provided with a plurality of laminated identification sheets for distinguishing the type of dry ice inside the box, the plurality of laminated identification sheets being stacked and attached to the side walls of the box body;
