Description

Technical Field

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

[0002] Vacuum insulation panels typically consist of a core material, a barrier film, and a getter. The manufacturing process involves encapsulating the core material and getter with the barrier film, followed by vacuum sealing. Vacuum insulation panels utilize the principle of vacuum insulation to achieve the goals of heat preservation and energy saving.

[0003] Getters, as an important component of vacuum insulation panels, absorb residual gases within the panel to maintain its vacuum level. Common getters include room-temperature getters and activated getters. Room-temperature getters are suitable for ordinary bag-type vacuum insulation panels, while activated getters require a high-temperature activation process. The barrier membrane of ordinary bag-type vacuum insulation panels cannot withstand the activation temperature, therefore activated getters are not suitable for bag-type getters and are only suitable for high-temperature resistant metal vacuum insulation panels.

[0004] Traditional activation methods for getter in metal vacuum insulation panels include overall activation and local activation. Overall activation involves baking and heating the entire panel, which has drawbacks such as long heating time, high energy consumption, and the potential for yellowing of the surface. Local activation involves heating the getter area at a specific high temperature. However, localized high-temperature heating can cause wrinkling or deformation at the heated area, and precise temperature control during localized heating can damage the core material at that location. Utility Model Content

[0005] Based on the aforementioned problems in the prior art, the purpose of this application is to provide an in-plate activated vacuum insulation panel, which, by setting a high-temperature resistant barrier and a thickened layer on the high-temperature resistant barrier, with the getter to be activated located at the thickened layer, can effectively reduce the phenomenon of wrinkling or deformation on the surface of the high-temperature resistant barrier and damage to the core material when the getter to be activated in the vacuum insulation panel is heated and activated.

[0006] The technical solution adopted by this application to solve its technical problem is: an in-plate activated vacuum insulation board, including a high-temperature resistant barrier component, a core material, and a getter; a vacuum cavity is formed inside the high-temperature resistant barrier component, and a thickened layer is provided on the high-temperature resistant barrier component; the core material is disposed in the vacuum cavity; the getter is disposed in the vacuum cavity, and the getter is located at the thickened layer.

[0007] Furthermore, the high-temperature resistant barrier includes a first barrier and a second barrier, with the edges of the first barrier and the edges of the second barrier sealed together.

[0008] Furthermore, the first barrier is a stainless steel foil, and the second barrier is a stainless steel base shell.

[0009] Furthermore, the thickened layer is made of stainless steel and is fixed to the inside of the stainless steel base shell.

[0010] Furthermore, the thickened layer is made of metal.

[0011] Furthermore, the core material is a high-temperature resistant core material.

[0012] Furthermore, the high-temperature resistant core material is a centrifugal cotton core material.

[0013] Furthermore, the getter is in the form of a tablet or powder.

[0014] Furthermore, the lower surface of the getter is in contact with the thickened layer.

[0015] Furthermore, a heat insulation block is provided on the upper surface of the getter.

[0016] The beneficial effects of this application are as follows: During manufacturing, the core material and the getter to be activated can be placed inside a high-temperature resistant barrier, and then vacuum-sealed to form a vacuum insulation panel. During activation, the thickened layer is heated, causing its temperature to rise, thereby activating the getter. During the heating process of the thickened layer, because the high-temperature resistant barrier has high-temperature resistance and the thickened layer is placed on top of it, the thickened layer can withstand higher temperatures, making it less likely to damage the high-temperature resistant barrier during heating. This effectively reduces wrinkling or deformation of the surface of the high-temperature resistant barrier during the heating process. Attached Figure Description

[0020] High-temperature resistant barrier 1, first barrier 11, second barrier 12, core material 2, getter 3, thickened layer 4, heat insulation block 5. Detailed Implementation

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, the present invention discloses an in-panel activated vacuum insulation panel, comprising a high-temperature resistant barrier 1, a core material 2, and a getter 3; a vacuum cavity is formed inside the high-temperature resistant barrier 1, and a thickened layer 4 is provided on the high-temperature resistant barrier 1; the core material 2 is disposed in the vacuum cavity; and the getter 3 is disposed in the vacuum cavity, with the getter 3 located at the thickened layer 4.

[0023] Thus, the vacuum insulation panel with in-plate activation involved in this utility model can be manufactured by placing the core material 2 and the getter 3 to be activated inside a high-temperature resistant barrier 1, and then sealing it under vacuum to form a vacuum insulation panel. During activation, the thickened layer 4 is heated, causing the temperature of the thickened layer 4 in a localized area of ​​the vacuum insulation panel to rise, thereby activating the getter 3. During the heating process of the thickened layer 4, because the high-temperature resistant barrier 1 has high-temperature resistance and the thickened layer 4 is placed on the high-temperature resistant barrier 1, the thickened layer 4 can withstand a high temperature, making it less likely to damage the high-temperature resistant barrier 1 during heating, thus effectively reducing wrinkling or deformation of the surface of the high-temperature resistant barrier during the heating process.

[0024] In a preferred embodiment of this invention, the high-temperature resistant barrier 1 includes a first barrier 11 and a second barrier 12, with the edges of the first barrier 11 and the second barrier 12 sealed together. The first barrier 11 and the second barrier 12 can be sealed together by heat sealing or welding.

[0025] Specifically, the first barrier 11 is a stainless steel foil, and the second barrier 12 is a stainless steel base. When the first barrier 11 and the second barrier 12 need to be sealed, they can be sealed by laser welding to ensure an airtight seal.

[0026] In this embodiment, the thickening layer 4 is made of stainless steel and is fixed to the inner side of the stainless steel base shell. The thickening layer 4 and the second barrier 12 are made of the same material. The thickening layer 4 can be integrally formed with the second barrier 12, or it can be fixed to the inner side of the second barrier 12 by welding. The thickening layer 4 can also be made of other metal materials with high temperature resistance.

[0027] In this embodiment, the core material 2 is a high-temperature resistant core material. For example, the high-temperature resistant core material is centrifugal cotton core material. Centrifugal cotton core material has excellent high-temperature resistance and excellent thermal insulation performance. Using centrifugal cotton core material as the high-temperature resistant core material makes it less likely to be damaged when the getter 3 to be activated is heated and activated.

[0028] Furthermore, the getter 3 is in the form of a sheet or powder. The lower surface of the getter 3 is in contact with the thickened layer 4, thereby allowing heat from the thickened layer 4 to be easily conducted to the getter 3 for heating and activation.

[0029] In this embodiment, a heat insulation block 5 is provided on the upper surface of the getter 3. During local high-temperature heating activation, the temperature generated during heating is high, which can easily burn the core material at the heating position inside the metal vacuum insulation panel. To address this, the present invention provides a heat insulation block 5, which serves as a heat insulation element. The heat insulation block 5 reduces heat conduction to the core material 2, preventing the core material 2 from overheating and being damaged.

[0030] 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.
