Heat preservation structure using vacuum insulated panels, and refrigerator

Abstract

The invention relates to the technical field of heat preservation devices, in particular to a heat preservation structure using vacuum insulated panels, and a refrigerator. The heat preservation structure using the vacuum insulated panels comprises two protective layers. At least one layer of the vacuum insulated panels and at least one foaming insulated layer are arranged between the two protective layers and are arranged in an alternate mode. An elastic material layer is arranged between each vacuum insulated panel and the corresponding foaming insulated layer. The heat preservation structure using the vacuum insulated panels, and the refrigerator have the beneficial effects that one elastic material layer is arranged between each vacuum insulated panel and the corresponding foaming insulated layer, the elastic material layers can absorb deformation generated by thermal expansion and chilling contraction, and the whole heat preservation structure is prevented from deformation; and the elastic material layers can have the function of tensioning the vacuum insulated panels and the foaming insulated layers, the debonding phenomenon is avoided, the adaptability of the heat preservation structure to high and low temperature environments is improved, and the reliability of the heat preservation structure and the reliability of thermal insulation properties are improved.

At present, the insulation structure using vacuum insulation panels is composed of a protective layer, a vacuum insulation panel layer and a foam insulation layer. This structure has the following technical disadvantages: 1. The insulation structure , in the high and low temperature environment, due to thermal expansion and contraction, the thermal insulation structure is prone to deformation; There will be debonding between the vacuum insulation panel and the foam insulation layer, which seriously affects the stability and insulation performance of the entire insulation structure; 3. Since the vacuum insulation panel is a thin barrier film, it is extremely It is easy to be damaged. The existing structure is easy to damage the barrier film of the vacuum insulation panel during the production process of the insulation structure, and the thermal insulation performance of the vacuum insulation panel will be invalid.
