Vacuum insulated panel and refrigerator

Abstract

The invention provides a vacuum insulated panel. The vacuum insulated panel comprises a core material and a clad material. The core material includes a glass fiber layer and a perforated foam layer, and the glass fiber layer and the perforated foam layer are arranged layer by layer in an overlaying mode, and groove structures are formed in the surface, deviating from the perforated foam layer, ofthe glass fiber layer. The clad material wraps the core material, vacuum is formed between the clad material and the core material, and containing parts for arranging external heat exchange pipelinesare arranged at the corresponding positions of the groove structures. The structure can avoid more glass fiber fragments in the glass fiber layer of the core material, prevent the clad material of thevacuum insulated panel from being destroyed, prevent the failure of the vacuum insulated panel, and reduce the thermal conductivity of the vacuum insulated panel.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a vacuum insulation panel and a refrigerator. Background technique [0002] In recent years, vacuum insulation panels have been widely used in cryogenic industries such as refrigerators and freezers due to their excellent low thermal conductivity and small size. Vacuum insulation panels are mainly composed of cladding material, core material and getter. [0003] However, the vacuum insulation panels used in existing refrigerators are often just ordinary square plates, and many refrigerators with built-in condenser systems have condensation pipes for heat dissipation attached to the side panels or back panels. Existing vacuum insulation panels are only suitable for locations where there is no condensation pipeline for heat dissipation. When there is a condenser pipeline at the side or back panel, other support components are required to isolate the vacuum insulati...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used solution is to prepare vacuum insulation panels with grooves. The general method is to prepare vacuum insulation panels with grooves by cutting or stamping the core material during the core material preparation process. When the core material is composed of glass fibers When punching or cutting, it is easy to cause the breakage of the glass fiber, resulting in an increase in its contact points, or an increase in the number of fragments. On the one hand, the thermal conductivity of the core material increases. Membrane material, leading to failure of vacuum insulation panels
