Title:
3D ANNULAR VACUUM INSULATION PANEL, AND THERMAL INSULATION CONTAINER
Document Type and Number:
WIPO Patent Application WO/2022/001299
Kind Code:
A1
Abstract:
Provided is a 3D annular vacuum insulation panel, comprising: an internal barrier layer, a middle core material and an external barrier layer, wherein the internal barrier layer is annular and has open faces at two axial ends thereof; the external barrier layer comprises an outwardly protruding portion which protrudes outwards in the radial direction of the internal barrier layer, and straight portions arranged on the upper and lower sides of the outwardly protruding portion in the axial direction of the internal barrier layer; and the straight portions are combined with the internal barrier layer to form a closed space between the outwardly protruding portion and the internal barrier layer for filling with the middle core material. The 3D annular vacuum insulation panel can effectively enhance the actual thermal insulation performance, extend the thermal insulation duration, and reduce the rejection rate, and is more energy-saving and environmentally friendly. A thermal insulation container is further provided, which uses the 3D annular vacuum insulation plate as described above.
