The invention discloses a cold storage box after double-layer sheathing and a rear vacuumizing layer. The cold storage box comprises a box body I, a box body II sheathed in the box body I and a heat-insulated supporting frame, wherein a gap is left between the box body I and the box body II; the heat-insulated supporting frame is arranged in the gap between the box body I and the box body II; and the bottom end of the heat-insulated supporting frame is connected with the bottom surface of the box body I, and the top end of the heat-insulated supporting frame is connected with the bottom surface of the box body II, and is clamped on the box body II. The cold storage box disclosed by the invention has the advantages that the structure is simple; the double-layer box bodies are adopted, can be sheathed for use and also can be used singly; and in the heat-insulating process, the influence of the environment and the weather on the heat-insulating effect of a heat-insulating layer is less, and the heat-insulating time of the heat-insulating layer is long.
Description
technical field [0001] The invention belongs to a cold storage box, in particular to a cold storage box with a double-layer suit and a vacuumized layer. Background technique [0002] Cold storage boxes or incubators are widely used in our daily life. Usually, thermal insulation foam materials are used to make the insulation layer, and the insulation layer is used to realize the insulation of the cold storage box or incubator. Fast, resulting in the temperature in the box not being maintained for a long time, and the heat preservation effect is not good enough; some cold storage boxes need uninterrupted electronic refrigeration to supplement the loss of cold capacity during the heat preservation process, which wastes energy and high cost of use. Contents of the invention [0003] In order to overcome the above-mentioned problems existing in the prior art field, the object of the present invention is to provide a double-packed cold storage box with a vacuumized layer, which ...
