Vacuum insulating layer with a plurality of unit cavities

Abstract

The invention discloses a vacuum insulating layer with a plurality of unit cavities. The vacuum insulating layer comprises an insulating layer body. The insulating layer body comprises a sealing layer on the front surface, a sealing layer on the back surface and side walls of a main cavity formed by connecting the peripheries of the sealing layers and the side walls. A cavity sealing layer is arranged between the sealing layer on the front surface in the main cavity and the sealing layer on the back surface in the main cavity and separates the main cavity into a front cavity and a rear cavity. Criss-cross sealing strips are arranged in the front cavity and the rear cavity respectively and separate the corresponding cavities into the independent airtight unit cavities, and the unit cavities in the front cavity and the unit cavities in the rear cavity are arranged in a staggered mode so that the sealing strips of the unit cavities in one cavity can be covered with the box spaces of the unit cavities in the other cavity. The sealing strips and the side walls are arranged on the front surface, the back surface and the cavity sealing layer respectively, and the junctions are provided with wedges, wedge holes and hooping positions so that the bonding strength of the junctions can be improved in the hole-free sealing process after vacuumizing of a vacuum chamber is completed. The vacuum insulating layer has the manufacturing characteristic of large-scale production of vacuum products.

Description

technical field [0001] The invention relates to a vacuum insulation layer with multiple unit cavities, in particular to a multi-seal unit cavity vacuum insulation layer with high strength, which can be seamlessly connected and covered with each other. Background technique [0002] Most of the thermal insulation structures on the market today use a foam layer, that is, a foamed thermal insulation layer such as polyester is filled between two layers of boards, and there are also hollow structures, which have relatively good thermal insulation performance, but in today’s huge resource consumption and climate deterioration , even if the foam layer or the hollow layer using FRP as the splint can no longer meet the needs of future insulation products for sustainable development. There are also vacuum layers, such as vacuum glass or other stacked fiber heat insulation boxes, etc., whose thermal insulation performance is much better than that of foam or hollow layers. It should be s...
