Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation panel technology, and in particular to a lightweight vacuum insulation panel. Background Technology

[0002] Vacuum insulation panels are a new type of heat insulation and energy-saving material made using the principle of vacuum insulation. They consist of a sealing material with high surface barrier properties, a core material with extremely strong heat insulation properties, and a desiccant or getter. The core material, desiccant, or getter are sealed in a vacuum using the sealing material. By utilizing the principle of vacuum insulation, the purpose of heat preservation and energy saving is achieved.

[0003] The core material of vacuum insulation panels is generally composed of porous materials with low thermal conductivity, while also possessing a certain degree of mechanical strength to ensure that the panel surface does not collapse and cause structural damage during the vacuuming process. There are various types of core materials for vacuum insulation panels. Based on their morphological and structural characteristics, core materials can generally be divided into four main categories: granular, foam, fiber, and composite core materials.

[0004] Some lightweight vacuum insulation panels use foam-based core materials, such as phenolic foam core materials, which contribute to their lightweight nature. The manufacturing process involves creating a groove on the upper surface of the foam core material, placing a getter inside, ensuring its lower surface adheres to the bottom of the groove, and then inserting the core material and getter into the vacuum insulation panel before vacuum sealing the opening. After manufacturing, the core material is compressed, and gaps exist between the groove and the getter, resulting in an uneven surface that affects the panel's performance. Utility Model Content

[0005] Based on the above-mentioned problems existing in the prior art, the purpose of this application embodiment is to provide a lightweight vacuum insulation board, which, by opening a side receiving groove on the side of the foam core material, makes the upper and lower surfaces of the vacuum insulation board flat after it is made.

[0006] The technical solution adopted by this application to solve its technical problem is: a lightweight vacuum insulation panel, including a barrier film bag, a core material and a getter;

[0007] The core material is a foam core material, which is encapsulated in the barrier film bag. A side receiving groove is provided on the side of the foam core material. The getter is placed in the side receiving groove, and the side of the getter abuts against the bottom of the side receiving groove.

[0008] Furthermore, the foam core material is a phenolic core material.

[0009] Furthermore, the side receiving groove is a rectangular receiving groove.

[0010] Furthermore, the getter is a rectangular parallelepiped-shaped getter.

[0011] Furthermore, the depth of the side receiving groove is equal to the length of the getter, the width of the side receiving groove is equal to the width of the getter, and the height of the side receiving groove is equal to the thickness of the getter.

[0012] Furthermore, the getter has a thickness of 3mm-7mm, a length of 26mm-34mm, and a width of 26mm-34mm.

[0013] Furthermore, the getter is located on one side of the sealing end of the barrier film bag.

[0014] Furthermore, the side receiving groove is located in the middle or upper part of the side of the core material.

[0015] Furthermore, it also includes a surface core material, which is disposed on the surface of the foam core material.

[0016] Furthermore, the foam core material has a side groove on its side; it also includes a desiccant, which is disposed in the side groove.

[0017] The beneficial effects of this application are as follows: Since the side of the foam core material is provided with a side receiving groove and the getter is placed in the side receiving groove, during the manufacturing process, the foam core material together with the getter in the side receiving groove is put into a barrier film bag, and the opening is vacuum heat-sealed to make a lightweight vacuum insulation board. The upper and lower surfaces of the lightweight vacuum insulation board are flat, and the getter is located on the side. After the vacuum insulation board is folded, the side of the lightweight vacuum insulation board is also relatively flat. Attached Figure Description

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3As shown, a lightweight vacuum insulation panel of this utility model includes a barrier film bag 1, a core material and a getter 3; the core material is a foam core material 2, which is encapsulated in the barrier film bag 1, and a side receiving groove 21 is provided on the side of the foam core material 2; the getter 3 is disposed in the side receiving groove 21, and the side of the getter 3 abuts against the bottom of the side receiving groove 21.

[0025] Thus, the lightweight vacuum insulation panel of this utility model has a side receiving groove 21 on the side of the foam core material 2, and the getter 3 is placed in the side receiving groove 21. During manufacturing, the foam core material 2 and the getter 3 in the side receiving groove 21 are put into a barrier film bag 1, and the opening is vacuum-sealed to form a lightweight vacuum insulation panel. The upper and lower surfaces of the lightweight vacuum insulation panel are flat, and the getter 3 is located on the side. After the vacuum insulation panel is folded, the side of the lightweight vacuum insulation panel is also relatively flat. Since the side of the getter 3 abuts against the bottom of the side receiving groove 21, the contact area between the getter 3 and the core material is large, which facilitates the getter 3 to absorb the gas remaining in the vacuum insulation panel.

[0026] In this embodiment, the foam core material 2 is a phenolic core material. Lightweight vacuum insulation panels made with phenolic core materials are widely used in the field of thermal insulation materials due to their light weight and good thermal insulation performance.

[0027] Furthermore, the side receiving groove 21 is a rectangular parallelepiped shape. Correspondingly, the getter 3 is also a rectangular parallelepiped shape. A side receiving groove 21 can be drilled into the side of the foam core material 2. Because the shape of the getter 3 matches the shape of the side receiving groove 21, it is easier for the getter 3 to be placed compactly within the side receiving groove 21. The depth of the side receiving groove 21 is equal to the length of the getter 3, the width of the side receiving groove 21 is equal to the width of the getter 3, and the height of the side receiving groove 21 is equal to the thickness of the getter 3.

[0028] Traditional getters are round-cap shaped, so a cylindrical groove is directly cut into the upper surface of the traditional foam core material, and the bottom of the round-cap shaped getter directly contacts the bottom of the cylindrical groove. However, this invention creates a side receiving groove 21 on the side of the foam core material 2. When creating the side receiving groove 21, holes are drilled from the outside inwards into the side of the core material, allowing a cuboid receiving groove to be created, facilitating the bottom of the side receiving groove 21 to abut against the side of the getter 3.

[0029] In this embodiment, the getter 3 has a thickness of 3mm-7mm, a length of 26mm-34mm, and a width of 26mm-34mm. Different specifications of getters 3 can be manufactured according to different specifications of vacuum insulation panels. The length and width of the getter 3 are usually above 20mm, while the core material thickness of some vacuum insulation panels is less than 20mm. Therefore, the side receiving groove 21 opened on the side of the foam core material 2 is flat, facilitating the side placement of the getter 3 into the side receiving groove 21.

[0030] Furthermore, the getter 3 is located on one side of the sealing end of the barrier film bag 1. During sealing, the opening of the barrier film bag 1 can be facing upwards. Since the getter 3 is located on one side of the sealing end of the barrier film bag 1, under the action of gravity, the side of the getter 3 abuts against the bottom of the side receiving groove 21, so that the getter 3 will not detach from the side receiving groove 21 during the sealing process.

[0031] The side receiving groove 21 is located in the middle or upper part of the side of the core material. In thicker core materials, the side receiving groove 21 is located at the upper part of the side of the core material. This allows the edge flaps to be folded towards the side receiving groove 21 onto the surface of the vacuum insulation board during folding, thus covering the barrier film outside the side receiving groove 21 and making the side of the vacuum insulation board relatively flat. In thinner core materials, the side receiving groove 21 is located in the middle of the side of the core material, making the portion of the core material above and below the side receiving groove 21 less prone to damage during vacuum sealing.

[0032] In a preferred embodiment, a surface core material 4 is also included, which is disposed on the surface of the foam core material 2. Phenolic core materials have low mechanical strength and are relatively brittle; therefore, a surface core material 4 is disposed on the upper and lower surfaces of the phenolic core material to protect it. This surface core material 4 is preferably a wet-processed core material, thereby making the upper and lower surfaces of the manufactured lightweight vacuum insulation board smoother.

[0033] In one embodiment, a side groove 22 is provided on the side of the foam core material 2; a desiccant 5 is also included, which is disposed in the side groove 22. By providing the side groove 22, the desiccant 5 can be easily contained, and by providing the desiccant 5, residual moisture in the core material can be adsorbed.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
