Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation panel technology, and in particular to a shell-type vacuum insulation panel with reliable sealing. Background Technology

[0002] Vacuum insulation panels effectively prevent heat transfer caused by air convection, significantly reduce thermal conductivity, and contain no ODS materials. They are environmentally friendly and energy-efficient, making them the world's most advanced high-efficiency insulation material.

[0003] Shell-type vacuum insulation panels typically consist of a barrier membrane, a core material, an adsorbent, and a barrier base shell. The edges of the barrier base shell and the barrier membrane are sealed together after vacuuming to form a vacuum cavity between them. The core material and adsorbent are then placed within this vacuum cavity. However, insufficient sealing strength can occur when sealing the edges of the barrier base shell and the barrier membrane, thus affecting the service life of the vacuum insulation panel. Summary of the Invention

[0004] Based on the above-mentioned problems existing in the prior art, the purpose of this application embodiment is to provide a shell-type vacuum insulation panel with reliable sealing. By setting a molten film, the molten film can be melted by heating after the shell-type vacuum insulation panel is made, so that it can be integrated into the sealing position, making the sealing reliable and the shell-type vacuum insulation panel with a long service life.

[0005] The technical solution adopted by this application to solve its technical problem is: a shell-type vacuum insulation panel with reliable sealing, comprising a barrier film, a barrier bottom shell, a core material, a molten film and an adsorbent; The edge of the barrier bottom shell is sealed together with the edge of the barrier film, and the sealing position forms a seal. A vacuum cavity is formed between the barrier bottom shell and the barrier film. The core material is disposed in the vacuum cavity. The molten film is located in the vacuum cavity. The molten film is disposed on the outside of the core material and on the inside of the seal position. The adsorbent is disposed in the vacuum cavity.

[0006] Furthermore, the barrier film is a high-temperature resistant barrier film, and the barrier base is a high-temperature resistant barrier base.

[0007] Furthermore, the melting points of the barrier film and the barrier base are higher than those of the molten film.

[0008] Furthermore, the barrier film is a metal barrier film, and the barrier base is a metal barrier base.

[0009] Furthermore, the barrier film is a stainless steel barrier film, and the barrier base is a stainless steel barrier base.

[0010] Furthermore, the core material is a high-temperature resistant core material.

[0011] Furthermore, the molten film covers the outside of the core material, and the molten film is provided with venting holes.

[0012] Furthermore, the molten film is tin foil.

[0013] The beneficial effects of this application are as follows: During manufacturing, the core material, adsorbent, and molten film are placed between the barrier film and the barrier bottom shell. After vacuuming, the barrier film and the barrier bottom shell are sealed together, thereby forming a vacuum cavity between them. Since the molten film is located on the outside of the core material and inside the sealing position, when the manufactured shell-type vacuum insulation panel is heated, the molten film melts and can be integrated into the sealing position. This results in a larger encapsulation area of ​​the barrier film and the barrier bottom shell at the sealing position, effectively improving the service life of the shell-type vacuum insulation panel.

[0016] 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.

[0017] like Figure 1 and Figure 2 As shown, this utility model discloses a shell-type vacuum insulation panel with reliable sealing, comprising a barrier film 1, a barrier bottom shell 2, a core material 3, a molten film 4, and an adsorbent 5; the edge of the barrier bottom shell 2 is sealed together with the edge of the barrier film 1, forming a seal at the sealing position, and a vacuum cavity is formed between the barrier bottom shell 2 and the barrier film 1, the core material 3 is disposed in the vacuum cavity, the molten film 4 is located in the vacuum cavity, the molten film 4 is disposed on the outside of the core material 3 and on the inside of the sealing position, and the adsorbent 5 is disposed in the vacuum cavity.

[0018] Thus, the shell-type vacuum insulation panel with reliable sealing involved in this utility model is manufactured by placing the core material 3, adsorbent 5, and molten film 4 between the barrier film 1 and the barrier bottom shell 2. After vacuuming, the barrier film 1 and the barrier bottom shell 2 are sealed together, thereby forming a vacuum cavity between them. Since the molten film 4 is located on the outside of the core material 3 and inside the sealing position, when the manufactured shell-type vacuum insulation panel is heated, the molten film 4 melts and can be integrated into the sealing position. This results in a larger sealing area for the barrier film 1 and the barrier bottom shell 2 at the sealing position, thereby effectively improving the service life of the shell-type vacuum insulation panel.

[0019] In this embodiment, the barrier film 1 is a high-temperature resistant barrier film, and the barrier shell 2 is a high-temperature resistant barrier shell. For example, if the barrier film 1 is a metal barrier film and the barrier shell 2 is a metal barrier shell, the melting points of the barrier film 1 and the barrier shell 2 are higher than the melting point of the molten film 4. Some metal materials have high-temperature resistance properties. Metal barrier films and metal barrier shells made of metal materials are less likely to be damaged when the molten film 4 is melted by heating the vacuum insulation panel. Specifically, the barrier film 1 is a stainless steel barrier film, and the barrier shell 2 is a stainless steel barrier shell. Stainless steel barrier films and stainless steel barrier shells have excellent high-temperature resistance properties, can withstand high temperatures, and are less likely to be damaged during heating.

[0020] In this embodiment, the core material 3 is a high-temperature resistant core material, such as an aerogel core material or a centrifugal cotton core material, so that the core material 3 is not easily damaged when the molten film 4 is melted by heating the shell-type vacuum insulation plate.

[0021] In a preferred embodiment of this invention, the molten film 4 covers the outer side of the core material 3, and vent holes are provided on the molten film 4. By pre-covering the outer side of the core material 3 with the molten film 4, the amount of core material 3 falling to the sealing position between the barrier film 1 and the barrier bottom shell 2 can be effectively reduced, thus making it less likely to affect the sealing between the barrier film 1 and the barrier bottom shell 2, resulting in good sealing performance after the barrier film 1 and the barrier bottom shell 2 are sealed. By providing vent holes on the molten film 4, gas inside the core material 3 can be easily extracted through the vent holes during vacuuming.

[0022] Furthermore, the molten film 4 is tin foil 41, which is wrapped around the outside of the core material 3. When the shell-type vacuum insulation board is heated, it is heated to the melting point temperature of the tin foil 41, which can be incorporated into the sealing position, thereby making the sealing film 1 and the sealing bottom shell 2 have a larger encapsulation area, thus effectively improving the service life of the shell-type vacuum insulation board.

[0023] 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.
