Description

Box structure with vacuum heat-insulating layer and refrigerator

Technical Field

The invention relates to the field of refrigerators, in particular to a refrigerator body structure with a vacuum heat-insulating layer and a refrigerator.

Background

The existing refrigerator forms a heat insulation layer in a foaming mode in a refrigerator body so as to achieve the purpose of heat insulation of the refrigerator. The thickness of the foaming layer of the refrigerator directly influences the heat leakage quantity of the refrigerator body. The thicker the foaming layer is, the better the heat preservation effect of the refrigerator is, but the thickness of the foaming layer is increased, the production cost is increased, and the volume ratio of the refrigerator body is reduced.

The vacuum box body is used for heat preservation, the heat transfer mode of the box body is changed from principle, and the original heat conduction of the foaming layer is changed into the radiation heat exchange of the vacuum layer. Under the same temperature difference, the radiant heat exchange quantity is irrelevant to the thickness of the heat preservation layer and only relevant to the radiant ratios of the two sides of the vacuum heat preservation layer, and the lower the radiant ratio is, the less the heat leakage quantity of the box body is.
