Description

Technical Field

[0001] The utility model relates to the technical field of vacuum insulation panels, in particular to a vacuum insulation panel with flat sides. Background Art

[0002] Vacuum insulation panel is a new type of high-efficiency insulation material made based on the principle of vacuum insulation. It combines the advantages of vacuum insulation, microporous insulation and multi-layer insulation, and thus has outstanding insulation effect.

[0003] A vacuum insulation panel typically includes a barrier film bag and a core material disposed within the barrier film bag. The core materials for vacuum insulation panels vary, and some core materials include air-permeable, impermeable powder bags and powdered materials. When preparing this core material, the powdered material is first placed within the air-permeable, impermeable powder bag, which is then sealed and finally placed in a press and pressed from top to bottom to form a plate-shaped core material. This core material is then placed within a barrier film bag, vacuumed, and heat-sealed to form a vacuum insulation panel. However, the core material formed by pressing the air-permeable, impermeable powder bag containing the powdered material has uneven sides, which results in uneven sides for the vacuum insulation panel, thus affecting its use. Utility Model Content

[0004] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present application is to provide a vacuum insulation panel with flat sides, which is provided by arranging an annular frame on the outside of the core material, and forming a flat surface on the outside of the annular frame, so that the sides of the vacuum insulation panel are flat, which facilitates the use of the vacuum insulation panel.

[0005] The technical solution adopted by the present application to solve its technical problem is: a vacuum insulation panel with flat sides, comprising a barrier film bag, a core material and an annular frame;

[0006] The core material is arranged in the barrier film bag, and the core material includes an air-permeable and impermeable powder bag and a powdery material, and the powdery material is arranged in the air-permeable and impermeable powder bag; the annular frame is arranged in the barrier film bag, the outer side of the annular frame forms a flat surface, and the inner side of the annular frame is in contact with the outer side of the air-permeable and impermeable powder bag.

[0007] Furthermore, the air-permeable and powder-impermeable bag is a non-woven bag, a glass fiber bag or a carbon fiber bag.

[0008] Furthermore, the powdery material is one or more of fumed silica, precipitated silica, expanded perlite, microsilica, fly ash, hollow glass microspheres, and expanded vermiculite.

[0009] Furthermore, the annular frame is an annular polyurethane frame or an annular phenolic frame.

[0010] Furthermore, the flat surface includes a first vertical surface, a transition connection surface and a second vertical surface, the first vertical surface is connected to the lower side of the transition connection surface, and the upper side of the transition connection surface is connected to the second vertical surface.

[0011] Furthermore, the distance between the plane where the first vertical surface is located and the plane where the second vertical surface is located is 0.1 mm-0.4 mm.

[0012] Furthermore, the transition connection surface is an inclined surface.

[0013] Furthermore, an adsorbent is provided on the core material.

[0014] The beneficial effects of the present application are: since the annular frame is arranged in the barrier film bag, a flat surface is formed on the outer side of the annular frame, and the inner side of the annular frame is fitted with the outer side of the air-permeable and powder-impermeable bag, so that after the vacuum insulation panel is completed, the inner side of the barrier film bag is fitted with the outer side of the annular frame, and the flat surface formed on the outer side of the annular frame makes the outer side of the barrier film bag flat, thereby making the side of the manufactured vacuum insulation panel flat, which is convenient for the use of the vacuum insulation panel.

[0021] Description of Reference Numerals

[0022] Barrier film bag 1, edge leaf 11, core material 2, air-permeable and impermeable powder bag 21, powdered material 22, annular frame 3, flat surface 31, first vertical surface 311, transition connection surface 312, second vertical surface 313, slot 32, adsorbent 4. DETAILED DESCRIPTION

[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6 As shown, the utility model is a vacuum insulation panel with flat sides, comprising a barrier film bag 1, a core material 2 and an annular frame 3; the core material 2 is arranged in the barrier film bag 1, the core material 2 comprises an air-permeable and impermeable powder bag 21 and a powdery material 22, and the powdery material 22 is arranged in the air-permeable and impermeable powder bag 21; the annular frame 3 is arranged in the barrier film bag 1, and a flat surface 31 is formed on the outer side of the annular frame 3, and the inner side of the annular frame 3 is in contact with the outer side of the air-permeable and impermeable powder bag 21.

[0025] In this way, the utility model relates to a vacuum insulation panel with flat sides. Since the annular frame 3 is arranged in the barrier film bag 1, a flat surface 31 is formed on the outside of the annular frame 3, and the inner side of the annular frame 3 is fitted with the outer side of the air-permeable and powder-impermeable bag 21. After the vacuum insulation panel is completed, the inner side of the barrier film bag 1 is fitted with the outer side of the annular frame 3, and the flat surface 31 formed on the outer side of the annular frame 3 makes the outer side of the barrier film bag 1 flat, thereby making the side of the manufactured vacuum insulation panel flat, which is convenient for the use of the vacuum insulation panel.

[0026] Optionally, the air-permeable, powder-impermeable bag 21 is a non-woven bag, a glass fiber bag, or a carbon fiber bag, and the powdered material 22 is one or more of fumed silica, precipitated silica, expanded perlite, microsilica, fly ash, hollow glass microspheres, and expanded vermiculite. After the powdered material 22 is placed in the air-permeable, powder-impermeable bag 21, during vacuuming, the gas within the powdered material 22 is extracted through the micropores formed in the air-permeable, powder-impermeable bag 21, while the powdered material 22 does not escape from the air-permeable, powder-impermeable bag 21, thereby achieving vacuuming of the core material 2.

[0027] In this embodiment, the annular frame 3 is an annular polyurethane frame or an annular phenolic frame. The annular polyurethane frame or annular phenolic frame has a certain hardness, which makes it difficult to break during the production of the vacuum insulation panel. Furthermore, the annular polyurethane frame or annular phenolic frame provides good thermal insulation, resulting in a low thermal conductivity coefficient for the vacuum insulation panel.

[0028] Furthermore, the flat surface 31 includes a first vertical surface 311, a transition surface 312, and a second vertical surface 313. The first vertical surface 311 is connected to the lower side of the transition surface 312, and the upper side of the transition surface 312 is connected to the second vertical surface 313. By providing the first vertical surface 311, the transition surface 312, and the second vertical surface 313, a slot 32 is formed on the side of the annular frame 3. This allows the edge blades 11 to be folded toward the slot 32 during hemming after the vacuum insulation panel is manufactured. The depth of the slot 32 can be equal to the thickness of the edge blade 11, resulting in a flat side of the vacuum insulation panel after hemming.

[0029] The transition surface 312 is an inclined surface. The angles formed by the inclined surface, the first vertical surface 311, and the second vertical surface 313 are both obtuse. The height of the first vertical surface 311 is equal to the height of the second vertical surface 313. This allows the slot 32 formed on the side of the annular frame 3 to open outward, facilitating the folding of the side blades 11 toward the slot 32. Furthermore, the distance between the plane containing the first vertical surface 311 and the plane containing the second vertical surface 313 is 0.1 mm to 0.4 mm.

[0030] In this embodiment, an adsorbent 4 is provided on the core material 2. The adsorbent 4 can absorb the gas remaining in the powdery core material 2, thereby increasing the vacuum degree and thus improving the thermal insulation effect of the vacuum insulation panel.

[0031] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
