[0001] The utility model relates to the technical field of heat insulation materials, and particularly relates to a vacuum insulation panel. Background Art
[0002] A vacuum insulation panel is a new type of thermal insulation material, which is made by enclosing a heat insulation core material and a getter in a high-barrier bag and then evacuating it. It effectively avoids heat transfer caused by air convection. Its fiber skeleton structure effectively reduces heat conduction. The outer high-barrier bag has extremely strong barrier to water and gas penetration, and its reflectivity can greatly reduce heat radiation, featuring high energy efficiency. It is widely used in fields such as refrigerators, insulation boxes, building walls, and refrigerated containers, playing the role of reducing energy consumption and improving economy, and having great development potential.
[0003] When manufacturing a vacuum insulation panel, after placing the core material in the barrier bag, evacuating and heat-sealing it, when breaking the vacuum, under the action of the external atmospheric pressure, the barrier bag will be flattened around the core material, thus forming a thin edge leaf around the core material. For easy use, it is necessary to fold the thin edge leaf, and during the folding process, it is necessary to pull the barrier film, which will cause damage to the barrier film and thus affect the performance of the vacuum insulation panel. Summary of the Utility Model
[0004] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a vacuum insulation panel, which realizes that the thin edge leaf does not need to be folded by setting a first protection plate and a second protection plate, with the first protection plate arranged on one side of the thin edge leaf and the second protection plate arranged on the other side of the thin edge leaf, so as to protect the side part of the plate body and not easily damage the barrier film.
[0005] The technical solution adopted by the present application to solve its technical problems is: a vacuum insulation panel, comprising a plate body, a first protection plate and a second protection plate;
[0006] The outer side part of the plate body has a thin edge leaf. The first protection plate is arranged on one side of the thin edge leaf, the second protection plate is arranged on the other side of the thin edge leaf, and the periphery of the second protection plate is connected to the periphery of the first protection plate so that the plate body is located inside the first protection plate and the second protection plate.
[0007] Further, the thin edge leaf includes a sealing edge and a virtual edge, and through holes are arranged on the sealing edge. The first protection plate and the second protection plate are connected together through the through holes.
[0008] Further, convex columns are arranged on the first protection plate, and the convex columns are located on one side of the through hole; slots are arranged on the second protection plate, and the slots are located on the other side of the through hole. The convex columns pass through the through holes and are inserted into the slots.
[0009] Further, the shape of the first protective plate is a loop-shaped frame, and the surface of the first protective plate is flush with the surface of the plate body.
[0010] Further, the shape of the second protective plate is a loop-shaped frame, and the surface of the second protective plate is flush with the surface of the plate body.
[0011] Further, the first protective plate is a polyurethane foam board; the second protective plate is a polyurethane foam board.
[0012] Further, the first protective plate is bonded to one side of the thin edge leaf, the second protective plate is bonded to the other side of the thin edge leaf, and the periphery of the second protective plate is bonded to the periphery of the first protective plate.
[0013] Further, a concave first relief groove is formed inside the first protective plate, and a concave second relief groove is formed inside the second protective plate.
[0014] Further, the thickness of the plate body is 8 mm - 35 mm.
[0015] The beneficial effect of this application is that during use, by arranging the first protective plate on one side of the thin edge leaf and the second protective plate on the other side of the thin edge leaf, the upper and lower sides of the thin edge leaf are protected. During the handling of the vacuum insulation panel, the first protective plate and the second protective plate protect the periphery of the plate body, making it difficult for the periphery of the vacuum insulation panel to be bruised. At the same time, the thin edge leaf is covered by the first protective plate and the second protective plate, and the thin edge leaf does not need to be folded, so it is not easy to damage the barrier film.

[0025] In this way, for a vacuum insulation panel involved in the present utility model, during use, by arranging the first protection plate 2 on one side of the thin edge blade 4 and the second protection plate 3 on the other side of the thin edge blade 4, the upper and lower sides of the thin edge blade 4 are protected. During the handling of the vacuum insulation panel, the first protection plate 2 and the second protection plate 3 protect the periphery of the panel body 1, making the periphery of the vacuum insulation panel not easily bruised. At the same time, the thin edge blade 4 is covered by the first protection plate 2 and the second protection plate 3, and the thin edge blade 4 does not need to be folded, so that the barrier film is not easily damaged.
[0026] Optionally, the thin edge blade 4 includes a sealing edge and a virtual edge, and a through hole 41 is provided on the sealing edge. The first protection plate 2 and the second protection plate 3 are connected together through the through hole 41. By providing the through hole 41, not only is the periphery of the second protection plate 3 connected to the periphery of the first protection plate 2, but also the first protection plate 2 and the second protection plate 3 are connected together through the through hole 41, thereby increasing the connection area between the first protection plate 2 and the second protection plate 3 and making the panel body 1 not easily separated from the first protection plate 2 and the second protection plate 3.
[0027] In some examples, a convex column 21 is provided on the first protection plate 2, and the convex column 21 is located on one side of the through hole 41; a slot 31 is provided on the second protection plate 3, and the slot 31 is located on the other side of the through hole 41. The convex column 21 passes through the through hole 41 and is inserted into the slot 31. By providing the convex column 21 and the slot 31, during installation, the convex column 21 is passed through the through hole 41 and inserted into the slot 31, thereby connecting the first protection plate 2 and the second protection plate 3 together. Among them, the shape of the convex column 21 can be frustum-shaped, and the shape of the slot 31 can also be frustum-shaped to facilitate the quick insertion of the convex column 21 into the slot 31.
[0028] Certainly, an adhesive can be applied to the positions of the first protection plate 2 and the second protection plate 3 above and below the through hole 41, so that the first protection plate 2 and the second protection plate 3 are bonded together through the through hole 41.
[0029] In this embodiment, the first protection plate 2 is in the shape of a rectangular frame, and the surface of the first protection plate 2 is flush with the surface of the plate body 1.
