Description

Multilayer vacuum bead, multilayer vacuum panel, and method of manufacturing said multilayer vacuum bead and said multilayer vacuum panel

[0001] The present invention relates to a multilayer vacuum bead, a multilayer vacuum panel, and a method for manufacturing the multilayer vacuum bead and the multilayer vacuum panel.

[0002] Vacuum insulation is an insulating material in which a thin film is wrapped around the outside of a porous core, and after reducing the internal pressure to create a vacuum, it is sealed. Vacuum insulation can have excellent thermal insulation performance because the thermal conductivity coefficient in a vacuum is close to zero.

[0003] Vacuum insulation is widely used in refrigerators, buildings, refrigerated vehicles, vending machines, and more. Since applying vacuum insulation to building exterior walls offers significant energy savings, it can be utilized as a key material for energy conservation.

[0004] To improve the performance of vacuum insulation and increase the reliability of maintaining a vacuum state, multilayer vacuum insulation materials such as multilayer vacuum beads and multilayer vacuum panels may be used.

[0005] Vacuum insulation with a multilayer structure can be produced by repeating the process of sealing the corresponding layer in a vacuum to form each layer.

[0006] The background technology described above is possessed or acquired by the inventor in the process of deriving the content of the disclosure of the present application, and cannot necessarily be considered as prior art disclosed to the general public prior to the filing of this application.

[0007] To manufacture multilayer vacuum insulation, the process of sealing each layer under a vacuum can be repeated. Since the process of forming a vacuum and sealing each layer is repeated, the cost and / or labor consumption for manufacturing multilayer vacuum insulation is high.

[0008] In multilayer vacuum insulation materials such as VIP (vacuum insulation panel), the internal vacuum state may be destroyed or weakened by gas penetration through the thermal fusion joints, which can lead to a decrease in the vacuum level.

[0009] According to various embodiments, a multilayer vacuum bead, a multilayer vacuum panel, a multilayer vacuum bead, and a method for manufacturing the multilayer vacuum panel can be provided by simultaneously shielding multiple layers in a vacuum state.

[0010] According to various embodiments, various types of insulating materials can be formed, and multilayer vacuum beads with high insulating performance can be provided.

[0057]

[0058] FIG. 1 is a drawing showing a multilayer vacuum bead according to various embodiments.

[0059] Referring to FIG. 1, vacuum beads according to various embodiments may include a bead body and a bead plug (105).

[0060] FIG. 1 illustrates an example of a multilayer vacuum bead comprising a first layer and a second layer, and the number of multiple layers of the multilayer vacuum bead is not limited to the example shown in FIG. 1.

[0061] For example, the bead body may include a plurality of layers, each including a gap and an internal space. As shown in FIG. 2, the bead body according to one embodiment may include a first layer and a second layer.

[0062] For example, a plurality of layers (e.g., a first layer and a second layer) may each include a gap and an internal space. A plurality of layers may each include a first bead body (101-1, 101-3) with a first gap formed therein and a second bead body (101-2, 103-2) with a second gap formed therein.

[0063] Referring to FIG. 1, a first layer according to one embodiment may include a first bead body (101-1) with a first gap formed therein and a second bead body (101-2) with a second gap formed therein.

[0064] Referring to FIG. 1, a second layer according to one embodiment may include a first bead body (103-1) with a first gap formed therein and a second bead body (103-2) with a second gap formed therein.

[0065] As shown in FIG. 1, the multiple layers may each have different sizes. For example, the diameter of the first layer formed by combining the first bead body (101-1) and the second bead body (101-2) may be different from the diameter of the second layer formed by combining the first bead body (103-1) and the second bead body (103-2).

[0066] The first bead body (101-1) of the first layer may include a first gap. The second bead body (101-2) of the first layer may include a second gap. When the first bead body (101-1) of the first layer and the second bead body (101-2) of the first layer are combined, a gap may be formed by the first gap and the second gap. The first gap and the second gap may be formed in the first bead body (101-1) of the first layer and the second bead body (101-2) of the first layer so as to correspond to each other.

[0067] The first bead body (103-1) of the second layer may include a first gap. The second bead body (103-2) of the second layer may include a second gap. The above description regarding the first gap, the second gap and / or gap of the first layer may be described substantially the same with respect to the first gap, the second gap and / or gap of the second layer, respectively.

[0068] The shape of the first gap and / or the second gap may be semicircular, but is not limited thereto, and the size of the first gap and / or the second gap may be formed in various sizes. In addition, the following description describes an example in which a first gap is formed in the first bead body (101-1) of the first layer and / or the first bead body (103-1) of the second layer, and a second gap is formed in the second bead body (101-2) of the first layer and / or the second bead body (103-2) of the second layer, but is not limited thereto. For example, a first gap may be formed in the first bead body (101-1) of the first layer and the first bead body (103-1) of the second layer, and a second gap may not be formed in the second bead body (101-2) of the first layer and the second bead body (103-2) of the second layer.

[0069] The shape and / or size of the gap formed by the first gap and / or the second gap may have various shapes and / or sizes. The shape and / or size of the gap formed by the first gap and / or the second gap may have various shapes and / or sizes depending on the layer.

[0070] For example, the bead plug (105) may be placed in the gap formed by the first gap and the second gap when the first bead body (101-1, 103-1) and the second bead body (101-2, 103-2) of each of the plurality of layers are combined.

[0071] According to one embodiment, as shown in FIG. 1, the bead plug (105) can be placed in the gap between a plurality of layers. For example, the bead plug (105) can be fused to a plurality of layers in a vacuum and can shield the gap between the plurality of layers.

[0072] Referring to FIG. 1, a bead plug (105) may be placed in the gap of the first layer and the gap of the second layer. For example, the size and / or shape of the gap of the first layer and the gap of the second layer may correspond to the size and / or shape of the bead plug (105).

[0073] As shown in FIG. 1, when the body portion of the bead plug (105) placed in the gap between the first and second layers is in the shape of a cylinder, the gap between the first and second layers may be circular.

[0074] For example, the size of the gap between the first and second layers may be larger than the size of the bead plug (105) by a set size. For example, in FIG. 1, the diameter of the gap between the first and second layers may be larger than the diameter of the body portion of the bead plug (105) by a set size. The shape of both ends of the bead plug (105) may be formed so that the bead plug (105) does not deviate from the gap between the multiple layers.

[0075] FIG. 1 illustrates an example in which a bead plug (105) is placed in the gap of the first layer and the gap of the second layer, but the bead plug (105) of the multilayer vacuum bead is not limited to the embodiment shown in FIG. 1.

[0076] For example, there may be multiple bead plugs (105). Each of the multiple bead plugs may correspond to multiple layers. For example, the first bead plug may correspond to the first layer (or the gap of the first layer), and the second bead plug may correspond to the second layer (or the gap of the second layer).

[0077] For example, the first bead plug may be placed in the gap of the first layer, and the second bead plug may be placed in the gap of the second layer.

[0078] FIG. 1 illustrates an example in which the shape, size, and / or location of the gap in the first layer and the gap in the second layer correspond. In the example illustrated in FIG. 1, since one bead plug (105) is placed in the gap in the first layer and the gap in the second layer, the shape, size, and / or location of the gap in the first layer and the gap in the second layer may correspond.

[0079] For example, the shape, size, and / or location of the gap in the first layer and the gap in the second layer may be different. Multiple bead plugs may each correspond to multiple layers. The size and shape of each bead plug (105) may correspond to the size and shape of the gap in the corresponding layer.

[0080] In FIGS. 2 to 10 below, an example is described in which one bead plug (105) is placed in the gap of a plurality of layers, but is not limited thereto, and a plurality of bead plugs may be placed in the gaps of corresponding layers.

[0081]

[0082] FIG. 2 is a diagram showing a method for manufacturing multilayer vacuum beads according to various embodiments.

[0083] A method for manufacturing a multilayer vacuum bead according to various embodiments may include the operation (210) of forming a bead body formed of a plurality of layers each including a gap and an internal space.

[0084] For example, the bead body can be formed with a bead plug (105) placed in the gap. For example, each of the plurality of layers can be combined with a bead plug (105) placed in the gap.

[0085] For example, the first bead body (101-1) and the second bead body (101-2) of the first layer can be joined with a bead plug (105) placed in the gap. The first bead body (101-1) of the first layer can be fused with the second bead body (101-2) of the first layer.

[0086] For example, the first bead body (103-1) and the second bead body (103-2) of the second layer can be joined with a bead plug (105) placed in the gap. The first bead body (103-1) of the second layer can be fused with the second bead body (103-2) of the second layer. After the first bead body (101-1) and the second bead body (101-2) of the first layer are joined, the second layer can be formed.

[0087] For example, a second layer can be formed while the formed first layer is placed inside the first bead body (103-1) and the second bead body (103-2). The first layer can be placed in the internal space of the second layer. The bead plug (105) placed in the gap of the first layer can be placed in the gap of the second layer. When the bead plug (105) is placed in the gap of the second layer, the first bead body (103-1) and the second bead body (103-2) of the second layer can be joined.

[0088] For example, a multilayer vacuum bead may include a core (or structure, support) for supporting between multiple layers. For example, the core may be placed between a first layer and a second layer. The core may prevent the first layer and the second layer from coming into contact. The core may support the first layer so that the first layer can be located within the internal space of the second layer.

[0089] For example, a method for manufacturing a multilayer vacuum bead may include the operation (220) of sealing the gap by fusing a bead plug (105) to a bead body in a vacuum state.

[0090] For example, in operation (220), the bead body and the bead plug (105) may be placed inside a vacuum chamber. The interior of the bead body (or the interior space of the first and second layers) may be in a vacuum state.

[0091] In a vacuum chamber, heat can be applied to the bead plug (105) to fuse the bead plug (105) to the bead body. The bead plug (105) can expand due to heat. The bead plug (105) can shield the gap (between the first layer and the second layer).

[0092]

[0093] FIG. 3 is a diagram showing a method for manufacturing a multilayer vacuum bead according to various embodiments.

[0094] According to various embodiments, a method for manufacturing a multilayer vacuum bead may include the operation (310) of forming a first layer with a bead plug (105) placed in the gap of the first layer.

[0095] For example, a bead plug (105) may be placed in the gap formed by the first bead body (101-1) and the second bead body (101-2). By applying heat to the bonding surface of the first bead body (101-1) and the second bead body (101-2), the first bead body (101-1) may be bonded to the second bead body (101-2). The first bead body (101-1) and the second bead body (101-2) may be bonded to form a first layer.

[0096] For example, a method for manufacturing a multilayer vacuum bead may include an operation (320) of forming a second layer with a bead plug (105) placed in the gap of the second layer.

[0097] For example, a bead plug (105) may be placed in the gap formed by the first bead body (103-1) and the second bead body (103-2). By applying heat to the bonding surface of the first bead body (103-1) and the second bead body (103-2), the first bead body (103-1) may be bonded to the second bead body (103-2). The first bead body (103-1) and the second bead body (103-2) may be bonded to form a second layer.

[0098] In operation (320), the second layer can be formed with the first layer disposed inside. A portion of the bead plug (105) disposed in the gap of the second layer can be disposed in the gap of the first layer.

[0099] When a multilayer vacuum bead includes a plurality of bead plugs, the plurality of bead plugs may each correspond to a plurality of layers. Each bead plug may be placed in the gap of the corresponding layer.

[0100] For example, a method for manufacturing a multilayer vacuum bead may include an operation (330) of fusing a bead plug (105) to a first layer and a second layer in a vacuum state to shield the gap of the first layer and the gap of the second layer.

[0101] In a vacuum, the bead plug (105) can expand due to applied heat. In a vacuum, the bead plug (105) can be fused to the first layer and the second layer by applied heat. In a vacuum, heat greater than the melting point of the bead plug (105) can be applied to the bead plug (105).

[0102] The bead plug (105) can be expanded by heat and fused to the first layer and the second layer. The bead plug (105) can shield the gap between the first layer and the second layer. Since the gap between the first layer and the second layer is shielded in a vacuum, the internal space of the first layer and the second layer can be in a vacuum state.

[0103]

[0104] FIGS. 4, FIGS. 5, and FIGS. 6 are drawings illustrating the fabrication process of multilayer vacuum beads according to various embodiments.

[0105] Figure 4 shows the state in which the first layer is formed among the first layer and the second layer of the bead body.

[0106] As shown in FIG. 4, the bead plug (105) can be placed in the gap formed by the first gap and the second gap when the first bead body (101-1) of the first layer and the second bead body (101-2) of the first layer are combined. For example, the bead plug (105) can be placed in the gap formed by the first gap of the first bead body (101-1) and the second gap of the second bead body (101-2).

[0107] For example, the first bead body (101-1) can be combined with the second bead body (101-2). For example, the first bead body (101-1) can be fused with the second bead body (101-2).

[0108] For example, when the bead plug (105) is placed in the gap, the gap of the first layer may not be shielded. As shown in FIG. 4, the body portion of the bead plug (105) may be smaller than the gap of the second layer. Both ends of the bead plug (105) may be larger than the gap of the first layer. Since both ends of the bead plug (105) are larger than the gap of the first layer, the first layer is not shielded, but the bead plug (105) may not deviate from the gap of the first layer.

[0109] The first bead body (103-1) and the second bead body (103-2) of the second layer can be combined after the first layer is formed.

[0110]

[0111] FIG. 5 is a drawing showing the state in which the second layer is formed in the state in which the first layer of the bead body of FIG. 4 is formed.

[0112] In substantially the same way that the first bead body (101-1) and the second bead body (101-2) of the first layer of FIG. 4 are combined, the first bead body (103-1) and the second bead body (103-2) of the second layer can be combined.

[0113] As shown in FIG. 5, the bead plug (105) can be placed in the gap formed by the first gap and the second gap when the first bead body (103-1) of the second layer and the second bead body (103-2) of the second layer are combined. For example, the bead plug (105) can be placed in the gap formed by the first gap of the first bead body (103-1) and the second gap of the second bead body (103-2).

[0114] For example, some of the bead plugs (105) placed in the gaps of the second layer may be placed in the gaps of the first layer. For example, if there are multiple bead plugs (105), bead plugs may be placed in the gaps of each layer.

[0115] As shown in FIG. 5, the second layer can be formed with the first layer positioned in the internal space of the second layer. For example, a core (or support) can be positioned between the first layer and the second layer. The core can prevent the first layer and the second layer from coming into contact. The core can support the first layer so that the first layer can be positioned in the internal space of the second layer.

[0116] For example, the core can be bonded to the first layer shown in FIG. 4. The core can be fused and bonded to the surface of the first layer (or the surface of the first bead body (101-1), the second bead body (101-2)).

[0117] For example, the core can be bonded to the second layer shown in FIG. 4. The core can be fused and bonded to the inner surface of the first bead body (103-1) and the second bead body (103-2) of the second layer.

[0118] For example, the first bead body (103-1) can be combined with the second bead body (103-2). For example, the first bead body (103-1) can be fused with the second bead body (103-2).

[0119] For example, when the bead plug (105) is placed in the gap, the gap of the second layer may not be shielded. As shown in FIG. 5, the body portion of the bead plug (105) may be smaller than the gap of the second layer. Both ends of the bead plug (105) may be larger than the gap of the second layer. Since both ends of the bead plug (105) are larger than the gap of the second layer, the second layer is not shielded, but the bead plug (105) may not be able to detach from the gap of the second layer.

[0120] The shape and / or size of the bead plug (105) is not limited to the examples shown in FIG. 1, FIG. 4 and FIG. 5. For example, the bead plug (105) may be formed with a shape and / or size such that, when placed in a gap, it does not shield the gap and does not deviate from the gap.

[0121] For example, the first bead body (101-1, 103-1), the second bead body (101-2, 103-2) and / or the bead stopper (105) may include an insulating material. For example, the insulating material may include, but is not limited to, EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), PIR (Polyisocyanurate), LCP (liquid crystal polymer), nanocomposite plastic, etc.

[0123] FIG. 6 shows the state in which the bead body and bead plug (105) of FIG. 5 are placed inside a vacuum chamber (110).

[0124] As shown in FIG. 6, the bead body may include a first layer (107) and a second layer (109). A bead plug (105) may be placed in the gap between the first layer (107) and the second layer (109). For example, the bead plug (105) may be placed to penetrate the gap of the first layer (107) and the gap of the second layer (109). The bead plug (105) may not shield the internal space of the bead body (or the first layer (107) and the second layer (109)).

[0125] For example, the bead body and bead plug (105) of FIG. 5 may be placed inside a vacuum chamber (110) as in FIG. 6. The vacuum chamber (110) can create a vacuum inside the vacuum chamber (110). For example, the vacuum state may represent an atmospheric state or a pressure state formed by the vacuum chamber (110). Since the gap of the bead body (or the gap of the first layer (107), the gap of the second layer (109)) is not shielded by the bead plug (105), the interior of the bead body (103) (or the interior of the first layer (107), the interior of the second layer (109)) can be made vacuum by the vacuum chamber (110).

[0126] For example, the bead plug (105) can be fused to the multiple layers by heat generated in a vacuum after the first bead body (101-1, 103-1) and the second bead body (101-2, 103-2) of each of the multiple layers (e.g., first layer (107), second layer (109)) are combined.

[0127] For example, the bead plug (105) can be fused to the bead body (or the first layer (107) and the second layer (109)) in a vacuum and can seal the gap. For example, the bead plug (105) can be fused to the first layer (107) and the second layer (109) by heat generated in a vacuum after the first layer (107) and the second layer (109) are formed.

[0128] For example, the bead plug (105) can be fused to the bead body (or the first layer (107) and the second layer (109)) by heat generated in a vacuum after the first bead body (101-1) and the second bead body (101-2) are combined and the first bead body (103-1) and the second bead body (103-2) are combined.

[0129] The bead plug (105) can expand by heat. The bead plug (105) can expand when it absorbs heat or energy. The bead plug (105) can expand to seal the gaps in the bead body (or, the first layer (107) and / or the second layer (109)). The bead plug (105) can be fused to the bead body (or, the first layer (107) and the second layer (109)).

[0130] Since the bead plug (105) shields the gap in a vacuum state, the interior of the bead body (or the interior space of the first layer (107) and the second layer (109)) can be shielded from the outside in a vacuum state.

[0131] For example, the bead plug (105) may include a material having a melting point different from the melting point of the bead body (or, the first layer (107) and the second layer (109)). When the bead plug (105) is heated above the melting point of the bead plug (105), it may fuse to the bead body (or, the first layer (107) and the second layer (109)) and seal the gap. When the bead plug (105) is heated above the melting point of the bead plug (105), it may fuse to each of the multiple layers and seal the gap.

[0132] For example, the melting point of the bead body (e.g., first bead body (101-1, 103-1), second bead body (101-2, 103-2)) may be higher than the melting point of the bead stopper (105). For example, the melting point of the bead body may be a first temperature, and the melting point of the bead stopper (105) may be a second temperature lower than the first temperature.

[0133] As shown in FIGS. 4 and 5, when the first bead body (101-1, 103-1) is fused to the second bead body (101-2, 103-2), heat may be applied only to the surface where the first bead body (101-1, 103-1) and the second bead body (101-2, 103-2) come into contact.

[0134] For example, in FIG. 4, since heat (e.g., heat above a first temperature) is applied only to the first bead body (101-1) and the second bead body (101-2), the first bead body (101-1) and the second bead body (101-2) can be fused and joined. In FIG. 4, since heat is applied only to the first bead body (101-1) and the second bead body (101-2), the bead plug (105) may not be fused to the first layer (107).

[0135] For example, in FIG. 5, since heat (e.g., heat above a first temperature) is applied only to the first bead body (103-1) and the second bead body (103-2), the first bead body (103-1) and the second bead body (103-2) can be fused and joined. In FIG. 5, since heat is applied only to the first bead body (101-3) and the second bead body (103-2), the bead plug (105) may not be fused to the second layer (109).

[0136] For example, heat may be applied to the inside of the vacuum chamber (110) so that it is above a second temperature and below a first temperature. For example, in FIG. 6, when the temperature inside the vacuum chamber (110) is above a second temperature and below a first temperature, the bead plug (105) may expand to seal the gap between the first layer (107) and the second layer (109). The bead plug (105) may be fused to the bead body (or the first layer (107) and the second layer (109)).

[0137] For example, the bead plug (105) may include a porous material into which moisture is adsorbed. The bead plug (105) may be fused to the bead body (or the first layer (107) and the second layer (109)) by heat generated when microwaves are applied within the vacuum chamber (110), and may shield the gap.

[0138] For example, a catalyst may be applied to the surface of the bead plug (105). When the catalyst reacts with a substance that reacts with the catalyst, heat may be generated. The bead plug (105) may be fused to the bead body (or the first layer (107) and the second layer (109)) by the heat generated when the catalyst reacts with the substance that reacts with the catalyst, and the gap may be sealed.

[0139] For example, a UV (ultraviolet) adhesive may be applied to the surface of the bead plug (105). When UV is irradiated onto the surface of the bead plug (105), the bead plug (105) fuses to the bead body (or, the first layer (107) and the second layer (109)) and can shield the gap.

[0140] In the above example, the bead plug (105) may adsorb water before being placed in the gap, or a catalyst or UV adhesive may be applied to the surface.

[0141] FIG. 6 illustrates an example in which a single bead body and a bead plug (105) coupled to the bead body are located in a vacuum chamber (110) for ease of understanding, but is not limited thereto. For example, a plurality of bead bodies and bead plugs coupled to the plurality of bead bodies may be located in the vacuum chamber (110).

[0142] When the bead body is located within the vacuum chamber (110), the internal space of the bead body (e.g., the internal space of the first layer (107) and the internal space of the second layer (109)) can be in a vacuum state because the diameter of the gap between the first layer (107) and the second layer (109) is larger than the diameter of the body portion of the bead plug (105).

[0143] For example, the bead plug (105) may include a through hole. For example, the through hole may be formed longitudinally in the center of the bead plug (105). For example, the through hole may be formed to connect the outside of the bead body with the internal space of the bead body (e.g., the internal space of the first layer (107)). Through the through hole of the bead plug (105), fluid flow between the internal space of the first layer (107) and the outside of the bead body may be possible. In the vacuum chamber (110), even if the internal space of the first layer (107) is shielded by the bead plug (105) due to pressure, the internal space of the first layer (107) may be in a vacuum state through the through hole.

[0144] For example, a through hole may be formed to connect the exterior of the bead body with the interior space of the second layer (109). Within the vacuum chamber (110), even if the interior space of the second layer (109) is shielded by the bead plug (105) due to pressure, the interior space of the second layer (109) can be vacuumed through the through hole.

[0145] When heat is applied to the bead plug (105) inside the vacuum chamber (110), the through hole can be shielded. For example, because the bead plug (105) expands due to heat, the through hole can be shielded.

[0146] For example, both ends of the bead plug (105) may be formed in a shape that prevents detachment from the gap and does not shield the gap. For example, both ends of the bead plug (105) may be formed in a cross shape. The size and / or length of the cross shape may be larger than the size of the gap. Even if the bead plug (105) placed in the gap is subjected to force in one direction by pressure, the bead plug (105) may not shield the gap.

[0147] For example, the body portion of the bead plug (105) can be formed in a shape corresponding to the shape of the gap.

[0148]

[0149] FIG. 7 is a diagram showing multilayer vacuum beads according to various embodiments.

[0150] When a bead plug (105) is fused to a bead body (or a plurality of layers) within the vacuum chamber (110) of FIG. 6, a multilayer vacuum bead (100) in which the interior of each layer is in a vacuum state can be created as shown in FIG. 7. The bead plug (105) of FIG. 6 is fused so that a fused bead plug (105-1) can be formed as shown in FIG. 7. Since the bead plug (105-1) is fused in a vacuum state and shields the gap of the bead body (or the gap of the first layer (107), the gap of the second layer (109)), the interior of the bead body (or the interior space of the first layer (107), the interior space of the second layer (109)) is in a vacuum state.

[0151] When manufacturing containers, insulation materials, etc., with an internal vacuum state, the internal state can be made vacuum, and then the parts through which air can flow can be fused to produce the containers, insulation materials, etc. When the parts through which air can flow are fused, the resulting gas may enter the interior of the containers, insulation materials, etc. The gas that enters the interior interferes with maintaining the vacuum state.

[0152] In the case of a multilayer vacuum bead (100) according to one embodiment, the area and / or range where the bead plug (107) is fused is small. Since the range where the bead plug (107) is fused is a local range, the amount of gas flowing into the multilayer vacuum bead (100) may be small. Because the amount of gas flowing into the multilayer vacuum bead (100) is small, the multilayer vacuum bead (100) can maintain a vacuum state inside for a long period of time.

[0153] Referring to FIGS. 6 and 7, a multilayer vacuum bead (100) according to various embodiments can be produced by heat applied to a bead plug (105) in a vacuum state. In a vacuum state, a vacuum bead (100) can be formed by applying mechanical force to a bead body (e.g., first bead body (101-1, 103-1), second bead body (101-2, 103-2)) and / or a bead plug (105), or while the bead (100) is in a stationary, fixed state.

[0154] For example, an aerogel (or aerogel) may be filled into the interior of the bead body (or the interior space of the first layer (107), the interior space of the second layer (109)). An aerogel is a solid material that represents a material filled with gas instead of liquid in a gel.

[0155]

[0156] FIG. 8 is a diagram showing a method for manufacturing a plurality of multilayer vacuum beads (e.g., the multilayer vacuum beads (100) of FIG. 7) according to various embodiments.

[0157] Referring to FIG. 8, a method for manufacturing a plurality of multilayer vacuum beads according to various embodiments may include the operation of aligning a plurality of first bead bodies (e.g., the first bead body (101-1) of FIG. 1, 4 and 5), a plurality of second bead bodies (e.g., the second bead body (101-2) of FIG. 1, 4 and 5), and a plurality of bead plugs (e.g., the bead plugs (105) of FIG. 1, 4 and 5). Each of the plurality of bead plugs may be located in the gap formed by the first bead body and the second bead body.

[0158] For example, a method for producing a plurality of multilayer vacuum beads may include an operation (820) of combining second bead bodies corresponding to each of the first bead bodies to create a plurality of first layers. A plurality of first layers may be formed by applying heat to the plurality of first bead bodies and the plurality of second bead bodies. Heat may not be applied to the plurality of bead plugs.

[0159] For example, a method for producing a plurality of multilayer vacuum beads may include an operation (830) of aligning a plurality of third bead bodies (e.g., the first bead body (103-1) of FIG. 1, FIG. 4 and FIG. 5), a plurality of fourth bead bodies (e.g., the second bead body (103-2) of FIG. 1, FIG. 4 and FIG. 5), a plurality of first layers, and a plurality of bead plugs.

[0160] For example, in operation (830), a plurality of first layers and a plurality of bead plugs may be located inside a plurality of third bead bodies and a plurality of fourth bead bodies. Each of the plurality of bead plugs may be located in the gap formed by the third bead body and the fourth bead body.

[0161] For example, a method for producing a plurality of multilayer vacuum beads may include the operation (840) of combining fourth bead bodies corresponding to each of the third bead bodies to create a plurality of second layers. A plurality of first layers may be formed by applying heat to the plurality of third bead bodies and the plurality of fourth bead bodies. Heat may not be applied to the plurality of bead plugs.

[0162] For example, a method for manufacturing a plurality of multilayer vacuum beads may include an operation (850) of fusing a plurality of bead plugs to a plurality of first layers and a plurality of second layers, respectively, in a vacuum state, thereby shielding the gaps of the plurality of first layers and the gaps of the plurality of second layers.

[0163] In operation (850), a plurality of bead plugs can be fused to a plurality of first layers and a plurality of second layers, respectively, under vacuum. Since the plurality of bead plugs are fused under vacuum, the internal space of the plurality of first layers and / or the plurality of second layers can be sealed under vacuum.

[0164]

[0165] FIGS. 9 and FIGS. 10 are drawings illustrating the fabrication process of multiple multilayer vacuum beads according to various embodiments.

[0166] Referring to FIG. 9, a method for manufacturing a plurality of multilayer vacuum beads according to one embodiment may include the operation of aligning a plurality of first bead bodies (120-1) coupled to a first guide member (e.g., the first bead body (101-1) of FIG. 1, FIG. 4 and FIG. 5), a plurality of second bead bodies (130-1) coupled to a second guide member (e.g., the second bead body (101-2) of FIG. 1, FIG. 4 and FIG. 5), and a plurality of bead plugs (140) coupled to a third guide member (e.g., the bead plug (105) of FIG. 1, FIG. 4 and FIG. 5).

[0167] For example, the first guide member, the second guide member, and the third guide member are members for assisting in the combination of a plurality of first bead bodies (120-1), a plurality of second bead bodies (130-1), and a plurality of bead plugs (140).

[0168] For example, by aligning the first guide member, the second guide member, and the third guide member, each of the plurality of first bead bodies (120-1), the plurality of second bead bodies (130-1), and the plurality of bead plugs (140) can be aligned in a position to produce the plurality of first layers.

[0169] For example, a plurality of first bead bodies (120-1) and a plurality of second bead bodies (130-1) may each be combined to form a plurality of first layers. Each of the plurality of first bead bodies (120-1) may include a first gap. Each of the plurality of second bead bodies (130-1) may include a second gap. Each of the plurality of first layers may include a gap formed by the first gap and / or the second gap.

[0170] A plurality of first bead bodies (120-1) may each include a first gap. A plurality of second bead bodies (130-1) may each include a second gap. A plurality of first layers may each include a gap formed by the first gap and / or the second gap.

[0171] For example, a plurality of first layers can be formed by applying heat only to a plurality of first bead bodies (120-1) and a plurality of second bead bodies (130-1). When the plurality of first layers are formed, heat may not be applied to each of the plurality of bead plugs (140). When the plurality of first layers are formed, the gaps between the plurality of first layers may not be shielded.

[0172] Referring to FIG. 9, a method for manufacturing a plurality of multilayer vacuum beads according to one embodiment may include aligning a plurality of third bead bodies (120-3) (e.g., the first bead body (103-1) of FIG. 1, FIG. 4 and FIG. 5) coupled to a first guide member, a plurality of fourth bead bodies (130-3) (e.g., the second bead body (103-2) of FIG. 1, FIG. 4 and FIG. 5) coupled to a second guide member, a plurality of first layers, and a plurality of bead plugs (140) coupled to a third guide member.

[0173] For example, a plurality of third bead bodies (120-3) and a plurality of fourth bead bodies (130-3) can each be combined to form a plurality of second layers. A plurality of second layers can be formed after a plurality of first layers are formed. A plurality of second layers can be formed after a plurality of first bead bodies (120-1) are each fused or combined with a plurality of second bead bodies (130-1).

[0174] Each of the plurality of third bead bodies (120-3) may have a different size from each of the plurality of first bead bodies (120-1). For example, when the first layer is located in the internal space of each of the plurality of second layers, each of the plurality of third bead bodies (120-3) may be larger than the plurality of first bead bodies (120-1).

[0175] Each of the plurality of fourth bead bodies (130-3) may have a different size from each of the plurality of second bead bodies (130-1). For example, when the first layer is located in the internal space of each of the plurality of second layers, each of the plurality of fourth bead bodies (130-3) may be larger than the plurality of second bead bodies (130-1).

[0176] A plurality of second layers may be formed with a plurality of first layers and a plurality of bead plugs (140) disposed in their respective internal spaces. For example, each of the plurality of bead plugs (140) may be disposed in the gaps of the second layer and the gaps of the first layer. A plurality of first layers may each be disposed in the internal spaces of the plurality of second layers.

[0177]

[0178] FIG. 10 is a drawing showing a plurality of first bead bodies (120-1), a plurality of second bead bodies (130-1), a plurality of third bead bodies (120-3), a plurality of fourth bead bodies (130-3) and a plurality of bead plugs (140) aligned according to a guide member.

[0179] FIG. 10 shows a state (150) in which a plurality of bead bodies are combined. In FIG. 10, a plurality of first layers and a plurality of bead plugs (140) may each be located inside a plurality of third bead bodies (120-3) and a plurality of fourth bead bodies (130-3).

[0180] Referring to FIG. 10, a method for manufacturing a plurality of multilayer vacuum beads according to one embodiment may include the operation of combining a fourth bead body (130-3) corresponding to each of a plurality of third bead bodies (120-3) to create a plurality of second layers. For example, in FIG. 10, heat may be applied only to the plurality of third bead bodies (120-3) and the plurality of fourth bead bodies (130-3) to form a plurality of second layers. When the plurality of second layers are formed, heat may not be applied to each of the plurality of bead plugs (140). When the plurality of second layers are formed, the gaps between the plurality of second layers may not be shielded.

[0181] For example, a method for manufacturing multiple multilayer vacuum beads may include the operation of fusing multiple bead plugs (140) to each of the multiple bead bodies in a vacuum state. For example, the multiple bead bodies and the multiple bead plugs (140) may be placed in a vacuum chamber (110).

[0182] For example, the temperature inside the vacuum chamber (110) can be controlled above the melting point of the plurality of bead plugs (140) to fuse the plurality of bead plugs (140) to each of the plurality of bead bodies. For example, the melting point of the plurality of bead plugs (140) may be lower than the melting point of the plurality of first bead bodies (120-1), the plurality of second bead bodies (130-1), the plurality of third bead bodies (120-3) and / or the plurality of fourth bead bodies (130-3). When the plurality of bead plugs (140) are fused to the plurality of bead bodies (or the plurality of first layers and the plurality of second layers), they can shield the gap between each of the plurality of bead bodies (or the gap between the plurality of first layers and the plurality of second layers).

[0183] For example, the plurality of bead plugs (140) may include a porous material to which water is adsorbed. When microwaves are irradiated in a vacuum, the plurality of bead plugs (140) may be fused to each of the plurality of bead bodies (or each of the plurality of first layers and the plurality of second layers) by the heat generated. When the plurality of bead plugs (140) are fused to the plurality of bead bodies, they may shield the gaps between each of the plurality of bead bodies (or the gaps between the plurality of first layers and the plurality of second layers).

[0184] For example, a catalyst may be applied to the surface of a plurality of bead plugs (140). When the catalyst reacts with a substance that reacts with the catalyst in a vacuum, the plurality of bead plugs (140) may be fused to each of the plurality of bead bodies (or each of the plurality of first layers and the plurality of second layers) by the heat generated. When the plurality of bead plugs (140) are fused to the plurality of bead bodies, they may shield the gaps between each of the plurality of bead bodies (or the gaps between the plurality of first layers and the plurality of second layers).

[0185] For example, a UV adhesive may be applied to the surface of a plurality of bead plugs (140). When UV is irradiated in a vacuum, the plurality of bead plugs (140) may be fused to each of the plurality of bead bodies (or each of the plurality of first layers and the plurality of second layers). When the plurality of bead plugs (140) are fused to the plurality of bead bodies, they may shield the gap between each of the plurality of bead bodies (or the gap between the plurality of first layers and the plurality of second layers).

[0186] Referring to FIGS. 9 and 10, a plurality of multilayer vacuum beads according to one embodiment can be produced within a single vacuum chamber. Conventional vacuum insulation materials (e.g., VIP (vacuum insulation panel)) are each manufactured under vacuum conditions. A plurality of multilayer vacuum beads according to one embodiment can be manufactured simultaneously under vacuum conditions.

[0187]

[0188] Insulating material can be manufactured using the multilayer vacuum beads (100) illustrated in FIGS. 1 to 10 above or the multilayer vacuum beads (100) manufactured according to the manufacturing method. For example, a plurality of multilayer vacuum beads (100) can be placed in a mold and heat can be applied to manufacture insulating material. The method of manufacturing insulating material using a plurality of multilayer vacuum beads (100) can be substantially the same as the method of manufacturing insulating material using known insulating materials.

[0189]

[0190] FIGS. 11 and FIGS. 12 are drawings showing an insulating material comprising a plurality of layers according to various embodiments.

[0191] Referring to FIGS. 11 and 12, an insulating material according to various embodiments may include a first layer (205, 209) formed of a plurality of multilayer vacuum beads (e.g., multilayer vacuum beads (100) of FIG. 7) and a second layer (201, 203, 207) formed of a plurality of insulating members.

[0192] In FIGS. 11 and 12, the insulating material comprising a plurality of layers may include a second layer (201, 203, 207) comprising a plurality of insulating members. For example, the plurality of insulating members may represent known insulating beads. For example, the second layer (201, 203, 207) may include insulating members such as EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), PIR (Polyisocyanurate), LCP (liquid crystal polymer), nanocomposite plastic, etc.

[0193] In FIGS. 11 and 12, the first layer (205, 209) may include a multilayer vacuum bead according to various embodiments, a multilayer vacuum bead produced according to a method for producing a multilayer vacuum bead, or a multilayer vacuum bead produced according to a method for producing a plurality of multilayer vacuum beads.

[0194] FIG. 11 is a drawing showing an insulating material comprising multiple layers made using a mesh partition. As in FIG. 7, a mesh partition (301, 303) is installed, and a plurality of multilayer vacuum beads according to one embodiment can be filled in the first layer (205). A plurality of insulating members (or a plurality of insulating beads) can be filled in the second layer (201, 203).

[0195] After filling with multiple multilayer vacuum beads and multiple insulating members, the mesh partition (301, 303) is removed and heat is applied to produce an insulating material containing multiple layers.

[0196] In FIG. 12, the second layer (207) may include panel insulation. For example, the panel insulation may represent a panel-shaped insulation made using a plurality of insulation members (or a plurality of insulation beads). A first layer (209) may be formed by filling a plurality of vacuum beads on one side of the panel insulation and applying heat. An insulation material comprising a plurality of layers (e.g., the first layer (207) and the second layer (209) of FIG. 12) may be produced by filling a plurality of vacuum beads on one side of the panel insulation and applying heat.

[0197]

[0198] FIGS. 13 and 14 are drawings showing a mixture of a multilayer vacuum bead (e.g., the multilayer vacuum bead (100) of FIG. 7) and an insulating member according to various embodiments.

[0199] In the following description regarding FIGS. 13 and FIGS. 14, the multilayer vacuum bead may represent a multilayer vacuum bead produced according to the multilayer vacuum bead or the method of producing a multilayer vacuum bead shown in FIGS. 1 to 10.

[0200] Figure 13 is a diagram showing an insulating material according to the mixing ratio of multilayer vacuum beads and insulating members.

[0201] In FIG. 13, the insulating material (401) represents an insulating material in which the ratio of multilayer vacuum beads is 100%. Referring to the insulating material (401) of FIG. 13, the insulating material according to various embodiments may include a plurality of multilayer vacuum beads.

[0202] In FIG. 13, the insulating material (403) represents an insulating material in which the ratio of multilayer vacuum beads is 50% and the ratio of insulating members is 50%. The insulating material (405) represents an insulating material made of a mixture of EPP and multilayer vacuum beads. The insulating material (407) represents an insulating material made of a mixture of PU (polyurethane) and multilayer vacuum beads.

[0203] Referring to the insulating material (403, 405, 407) of FIG. 13, the insulating material may include a plurality of insulating members.

[0204] Referring to the insulating material (401, 403) of FIG. 13, the insulating material according to various embodiments may be formed by mixing a plurality of multilayer vacuum beads and a plurality of insulating members (e.g., EPP, PU, ​​etc.) according to a set ratio, and fusing the mixed plurality of multilayer vacuum beads and the plurality of insulating members.

[0205] The thermal insulation performance of the insulation material can be determined according to the mixing ratio of multiple multilayer vacuum beads and multiple insulation members. The insulation material can be manufactured with a mixing ratio according to the required thermal insulation performance.

[0206] The thermal insulation performance of the insulation material can be determined according to the types of multiple insulating members mixed with multiple multilayer vacuum beads. By determining the types of insulating members based on the required thermal insulation performance, the insulation material can be manufactured.

[0207] For example, the type and ratio of the insulating material to be mixed can be determined according to the target temperature and / or target time. For example, the insulating material (405) may represent an insulating material produced according to the determined insulating material and mixing ratio when the target temperature is -10°C and the target time is 48 hours. For example, the insulating material (407) may represent an insulating material produced according to the determined insulating material and mixing ratio when the target temperature is -10°C and the target time is 72 hours.

[0208] As shown in the example illustrated in FIG. 13, the thermal insulation performance of a thermal insulation material comprising a plurality of multilayer vacuum beads and / or a plurality of insulating members can be determined according to the type and / or mixing ratio of the insulating members mixed.

As shown in FIG. 14, at least one insulating member (501) can be combined on the surface of the multilayer vacuum bead (100). For example, if the surface of the multilayer vacuum bead (100) is melted, a plurality of insulating members (501) can be combined (or fused, attached) to the multilayer vacuum bead. For example, if a liquid is applied to the surface of the multilayer vacuum bead, a plurality of insulating members (501) can be combined to the multilayer vacuum bead.

[0211] For example, the insulating material (403) of FIG. 13 can be manufactured using a multilayer vacuum bead (100) combined with an insulating member (501) shown in FIG. 14.

[0212]

[0213] FIGS. 15, 16, and 17 are drawings showing an adsorbent included in a multilayer vacuum bead (e.g., the multilayer vacuum bead (100) of FIG. 7) according to various embodiments.

[0214] In FIGS. 15, 16 and 17 below, the adsorbent (600) may represent an object (or solid) capable of adsorbing gas onto its surface. Gas interferes with maintaining a vacuum state. The adsorbent (600) can adsorb gas to assist in maintaining a vacuum state inside the vacuum bead.

[0215] FIG. 15 is an example showing a bead plug (105) containing a corresponding adsorbent (600).

[0216] Referring to FIG. 15, a bead plug (105) according to one embodiment may include an adsorbent.

[0217]

[0218] FIG. 16 is an example showing a bead body containing an adsorbent (600) in an internal space.

[0219] Referring to FIG. 16, a bead body according to one embodiment may include an adsorbent (600) in an internal space. For example, the bead body may include an adsorbent (600) in an internal space of a first layer and / or an internal space of a second layer.

[0220] For example, the adsorbent (600) may be located in the internal space of the first layer. The adsorbent (600) may be located in the internal space formed by the first bead body (101-1) and the second bead body (101-2) of the first layer.

[0221] For example, the adsorbent (600) may be located in the internal space of the second layer. The adsorbent (600) may be located in the internal space formed by the first bead body (103-1) and the second bead body (103-2) of the second layer.

[0222]

[0223] FIG. 17 is an example showing a first bead body (101-1) and a second bead body (101-2) including an adsorbent (600).

[0224] Referring to FIG. 17, a bead body according to one embodiment may include an adsorbent (600). FIG. 17 illustrates an adsorbent (600) included in a first bead body (101-1) and a second bead body (101-2) of a first layer, but is not limited thereto. For example, a first bead body (103-1) and / or a second bead body (103-2) of a second layer may include an adsorbent (600).

[0225] As shown in FIGS. 15 and 17 above, if the bead plug (105) or the bead body includes an adsorbent (600), the process of adding the adsorbent (600) during the process of making a multilayer vacuum bead can be reduced.

[0226] In the description of FIGS. 1 to 17 above, the multilayer vacuum bead (100) is described in the case where it is spherical, but the size and / or shape of the multilayer vacuum bead (100) is not limited to the examples shown in FIGS. 1 to 17. For example, the multilayer vacuum bead may have a cuboid shape, and the first bead body and the second bead body of the first layer and / or second layer may be cuboids with one side open.

[0227]

[0228] With respect to the multilayer vacuum panels of FIGS. 18 to 23 below, substantially identical details regarding the multilayer vacuum beads (100) described in FIGS. 1 to 17 may be omitted. Therefore, even if omitted, the details described regarding the multilayer vacuum beads (100) of FIGS. 1 to 17 may be applied substantially identically to the multilayer vacuum panels of FIGS. 18 to 23.

[0229]

[0230] FIG. 18 is a drawing showing a multilayer vacuum panel according to various embodiments.

[0231] Referring to FIG. 18, a multilayer vacuum panel according to various embodiments may include a panel body, a panel plug, and at least one core.

[0232] FIG. 18 shows a cross-section of multiple layers, wherein the first layer (701) may be located inside the second layer (703).

[0233] For example, the panel body may include a plurality of layers, each including a gap and an internal space. FIG. 18 illustrates a panel body including a first layer (701) and a second layer (703), but the number of layers is not limited to the example shown in FIG. 18.

[0234] For example, the panel body (e.g., first layer (701), second layer (703)) and / or the panel cap (711, 713) may include an insulating material. For example, the insulating material may include EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), PIR (Polyisocyanurate), LCP (liquid crystal polymer), nanocomposite plastic, etc. Additionally, the panel body may include a metal material, but is not limited thereto.

[0235] For example, a plurality of layers may each be formed to include a gap and an internal space. For example, the first layer (701) may include a first panel body with a first gap formed therein and a second panel body with a second gap formed therein. The first panel body may be combined with the second panel body to form the first layer. The first panel body may be combined with the second panel body to form a gap.

[0236] For example, the panel plug (711) may be placed in the gap formed by the first gap and the second gap when the first panel body of the first layer (701) is coupled to the second panel body.

[0237] For example, multiple layers can be formed from a flexible material such as a metal material. Multiple layers can be formed using a flexible material so that panel plugs (711, 713) are placed in each gap.

[0238] The first layer (701) may be formed with a panel plug (711) placed in the gap of the first layer (701). The first layer (701) may be located in the internal space of the second layer (703) while being supported by cores (721, 723, 725, 727).

[0239] For example, the second layer (703) may include the first layer (701) in its internal space. The second layer (703) may be formed so that a panel plug (713) is placed in the gap. Regarding the method of forming the second layer (703), the method of forming the first layer (701) may be applied substantially the same way.

[0240] For example, the panel plug (713) may be placed in the gap formed by the first gap and the second gap when the first panel body of the second layer (703) is coupled to the second panel body.

[0241] For example, panel plugs (711, 713) can be placed in the gap between multiple layers. For example, panel plugs (711, 713) can be fused to multiple layers in a vacuum and can shield the gap between multiple layers.

[0242] For example, the panel plugs (711, 713) may not shield the gap between multiple layers. The panel plugs (711, 713) may be placed in the gap between multiple layers. The panel plugs (711, 713) may not deviate from the gap between multiple layers. With respect to the panel plugs (711, 713), the description of the bead plug (105) described in FIGS. 1 to 17 may be applied substantially the same way.

[0243] For example, the panel plugs (711, 713) can expand by absorbing heat or energy. The panel plugs (711, 713) can fuse to multiple layers by absorbing heat or energy.

[0244] For example, the panel plug (711) can be fused to the first layer (701) in a vacuum and can shield the gap of the first layer (701). The panel plug (713) can be fused to the second layer (703) in a vacuum and can shield the gap of the second layer (703).

[0245] For example, panel plugs (711, 713) can be fused to multiple layers in a vacuum. For example, the first layer (701), the second layer (703), and the panel plugs (711, 713) shown in FIG. 18 can be placed in a vacuum chamber. The panel plugs (711, 713) placed in the gaps of each layer can absorb heat or energy in a vacuum and be fused to multiple layers.

[0246] For example, the panel plug (711, 713) may include a material having a melting point different from the melting point of the panel body (or, the first layer (701) and the second layer (703)). When the panel plug (711, 713) is heated above the melting point of the panel plug (711, 713), it may be fused to the panel body (or, the first layer (701) and the second layer (702)) and shield the gap. When the panel plug (711, 713) is heated above the melting point of the panel plug (711, 713), it may be fused to each of the plurality of layers and shield the gap.

[0247] For example, at least one core (721, 723, 725, 727) can support between multiple layers. For example, the core (721, 723, 725, 727) can support between the first layer (701) and the second layer (703). The core (721, 723, 725, 727) can support the first layer (701) so that the first layer (701) can be located inside the second layer (703).

[0248] For example, among the multiple layers, an outer layer may have an outer layer formed on its outer surface. For example, the outer layer may include multiple layers formed of a material (e.g., PET (polyethylene terephthalate), LDPE (low density polyethylene), AL, L-LDPE (linear low-density polyethylene)) to prevent fluid flow from the outside into the interior of the multilayer vacuum panel and to prevent the exchange of heat or energy.

[0249] For example, the multilayer vacuum panel may include an adsorbent (731, 733). For example, at least one layer among the plurality of layers may include an adsorbent (731, 733) in its internal space.

[0250] According to one embodiment, the internal space of a plurality of layers (e.g., a first layer (701), a second layer (703)) of a multilayer vacuum panel can be shielded from the vacuum state. The internal space of a plurality of layers of the multilayer vacuum panel can be shielded from the external space simultaneously.

[0251] A multilayer vacuum panel according to one embodiment can simultaneously shield or seal multiple layers into a vacuum state without the need to form a vacuum state each time each layer is shielded or sealed.

[0252] According to one embodiment, the internal space of a plurality of layers can be shielded or sealed by panel plugs (711, 713). Since the area heat-fused by the panel plugs (711, 713) is a local area, the amount of gas generated by heat fusion may be small. Since the amount of gas generated by heat fusion is small, the amount of gas flowing into the interior of the plurality of layers may be small. Since gas flowing into the interior of the vacuum panel is a factor that lowers the vacuum level, the multilayer vacuum panel according to one embodiment can maintain the vacuum level of the internal space for a long time.

[0253]

[0254] FIG. 19 is a drawing showing a method for manufacturing a multilayer vacuum panel according to various embodiments.

[0255] Referring to FIG. 19, a method for manufacturing a multilayer vacuum panel according to various embodiments may include the operation (1910) of forming a panel body formed of a plurality of layers each including a gap and an internal space.

[0256] For example, in operation (1910), a panel body can be formed with panel plugs (711, 713) placed in the gap. For example, the first layer (701) can be formed with panel plugs (711) placed in the gap of the first layer (701). The second layer (703) can be formed with panel plugs (713) placed in the gap of the second layer (703).

[0257] For example, a plurality of layers may be supported by at least one core. For example, the first layer (701) may be supported by cores (721, 723, 725, 727). The first layer (701) may be supported by cores (721, 723, 725, 727) and located in the internal space of the second layer (703).

[0258] For example, a method for manufacturing a multilayer vacuum panel may include the operation (1920) of sealing the gap by fusing the panel plug to the panel body in a vacuum state.

[0259] For example, the panel body (e.g., first layer (701) and second layer (703)) and the panel plug (711, 713) may be placed in a vacuum chamber. The panel plug (711, 713) may absorb heat or energy in a vacuum state. The panel plug (711, 713) may expand by absorbing heat or energy. The panel plug (711, 713) may fuse to the panel body (or, first layer (701), second layer (703)) by absorbing heat or energy. The panel plug (711, 713) may shield the gap between multiple layers (e.g., first layer (701) and second layer (703)).

[0260]

[0261] FIG. 20 is a diagram showing a method of manufacturing a multilayer vacuum panel according to various embodiments.

[0262] Referring to FIG. 20, a method for manufacturing a multilayer vacuum panel according to various embodiments may include an operation (2010) of forming a first layer with a panel plug placed in the gap of the first layer.

[0263] For example, in operation (2010), a first panel body with a first gap formed and a second panel body with a second gap formed may be combined to form a first layer (701). The first gap may correspond to the location, size, and / or shape of the second gap formed in the second panel body. The second gap may correspond to the location, size, and / or shape of the first gap formed in the first panel body. The first layer (701) may be formed with a panel plug (711) placed in the gap.

[0264] For example, the first layer (701) may be formed of a flexible material such as a metal material. In operation (2010), the first layer (701) may be formed so that a panel plug (711) is placed in the gap.

[0265] For example, a method for manufacturing a multilayer vacuum panel may include an operation (2020) of supporting the first layer and the second layer using at least one core between the first layer and the second layer.

[0266] For example, as shown in FIG. 18, cores (721, 723, 725, 727) can support the first layer (701). The cores (721, 723, 725, 727) can cause the first layer (701) to be spaced apart from the second layer (703) and the first layer (701) to be located inside the second layer (703).

[0267] For example, a method for manufacturing a multilayer vacuum panel may include an operation (2030) of forming a second layer while a panel plug is placed in the gap of the second layer.

[0268] For example, in operation (2030), a first panel body with a first gap formed and a second panel body with a second gap formed may be combined to form a second layer (703). The first gap may correspond to the location, size, and / or shape of the second gap formed in the second panel body. The second gap may correspond to the location, size, and / or shape of the first gap formed in the first panel body. The second layer (703) may be formed with a panel plug (713) placed in the gap.

[0269] At least one of the size, shape, and / or form of the first panel body and the second panel body forming the first layer (701) and the first panel body and the second panel body forming the second layer (703) may be different. For example, as shown in FIG. 18, the first panel body and the second panel body forming the second layer (703) may be larger than the size of the first panel body and the second panel body forming the first layer (701).

[0270] For example, the second layer (703) may be formed of a flexible material such as a metal material. In operation (2030), the second layer (703) may be formed so that a panel plug (713) is placed in the gap.

[0271] For example, a method for manufacturing a multilayer vacuum panel may include an operation (2040) of sealing the gaps of the first layer and the second layer by fusing panel plugs (711, 713) to the first layer and the second layer in a vacuum state.

[0272] For example, in operation (2040), the panel plug (711) can be fused to the first layer (701). The panel plug (711) can expand by absorbing heat or energy in a vacuum. The panel plug (711) can shield, seal, or seal the gap of the first layer (701). Since the gap of the first layer (701) is shielded in a vacuum, the internal space of the first layer (701) can be in a vacuum.

[0273] For example, in operation (2040), the panel plug (713) can be fused to the second layer (703). The panel plug (713) can expand by absorbing heat or energy in a vacuum. The panel plug (713) can shield, seal, or seal the gap of the second layer (703). Since the gap of the second layer (703) is shielded in a vacuum, the internal space of the second layer (703) can be in a vacuum.

[0274] For example, the panel plugs (711, 713) may include a porous material into which moisture is adsorbed. The panel plugs (711, 713) may be fused to a plurality of layers (e.g., a first layer (701) and a second layer (703)) by heat generated when microwaves are applied in a vacuum chamber, and may shield the gaps.

[0275] For example, a catalyst may be applied to the surface of the panel plugs (711, 713). When the catalyst reacts with a substance that reacts with the catalyst, heat may be generated. The panel plugs (711, 713) may be fused to (e.g., the first layer (701) and the second layer (703)) by the heat generated when the catalyst reacts with the substance that reacts with the catalyst, and the gaps may be sealed.

[0276] For example, a UV (ultraviolet) adhesive may be applied to the surface of the panel plug (711, 713). When UV is irradiated onto the surface of the panel plug (711, 713), the panel plug (711, 713) fuses to (e.g., the first layer (701) and the second layer (703)) and can shield the gap.

[0277] In the above example, the panel plugs (711, 713) may adsorb water before being placed in the gap, or a catalyst or UV adhesive may be applied to the surface.

[0278] In operation (2040), the internal space of the first layer (701) and the second layer (703) can be shielded, sealed, or sealed in the same vacuum environment. Compared to the method of manufacturing a multilayer vacuum insulation material in which a vacuum state must be formed each time a layer is formed, the multilayer vacuum panel according to one embodiment is easy to manufacture and the manufacturing cost can be reduced because multiple layers are shielded in a vacuum state in the same vacuum environment.

[0279] A multilayer vacuum panel according to one embodiment can shield the internal space of a plurality of layers to a vacuum state by applying heat to the panel plugs (711, 713) without performing mechanical operation in a vacuum environment.

[0280]

[0281] With respect to FIGS. 21, 22, and 23 below, content that overlaps with the content described in FIGS. 18, 19, and 20 above may be omitted. Even if the description is omitted with respect to FIGS. 21, 22, and 23, the content described with respect to FIGS. 18, 19, and 20 may be applied substantially the same way.

[0282]

[0283] FIGS. 21, FIGS. 22 and FIGS. 23 are drawings showing multilayer vacuum panels according to various embodiments.

[0284] FIG. 21 is a drawing showing a multilayer vacuum panel comprising three layers (e.g., a first layer (701), a second layer (703), and a third layer (705)) among various embodiments.

[0285] Referring to FIGS. 18 and FIGS. 21, the number of multiple layers can be formed in various ways. In a multilayer vacuum panel according to one embodiment, multiple layers can be shielded in a vacuum state in the same vacuum environment regardless of the number of layers.

[0286] For example, referring to FIG. 21, the gap between the first layer (701), the second layer (703), and the third layer (705) can be shielded by panel plugs (711, 713, 715). The panel plugs (711, 713, 715) can be expanded by heat or energy generated (or absorbed) in the same vacuum environment. The panel plugs (711, 713, 715) can be fused to the first layer (701), the second layer (703), and the third layer (705) by heat or energy generated (or absorbed) in the same vacuum environment. The panel plugs (711, 713, 715) can shield the gap between the first layer (701), the second layer (703), and the third layer (705) in the same vacuum environment.

[0287]

[0288] FIG. 22 is a drawing showing an example in which a panel plug (717) is placed in the gap between a plurality of layers (e.g., a first layer (701), a second layer (703)) among various embodiments.

[0289] Referring to FIG. 22, a panel plug (717) according to one embodiment may be positioned through the gaps of a plurality of layers aligned in one direction. For example, as shown in FIG. 22, the gaps of the first layer (701) and the gaps (703) of the second layer may be aligned in one direction (e.g., the right direction or the 3 o'clock direction in FIG. 22). For example, the gaps of the first layer (701) may correspond in position, size, and / or shape to the gaps (703) of the second layer.

[0290] With respect to the core (721, 723, 725, 727) and adsorbent (731, 733), the description of the core (721, 723, 725, 727) and adsorbent (731, 733) described in FIG. 18 may be applied substantially the same way.

[0291]

[0292] FIG. 23 is a drawing showing an example in which panel plugs (711, 713) are arranged in correspondence with each of the gaps of a plurality of layers (e.g., a first layer (701), a second layer (703)).

[0293] Referring to FIG. 23, panel plugs (711, 713) according to various embodiments may be arranged to correspond to each of the gaps of a plurality of layers.

[0294] For example, the panel plug (713) may be positioned in correspondence with the gap of the second layer (703) formed in one direction (e.g., the right direction or the 3 o'clock direction in FIG. 23).

[0295] For example, the panel plug (711) may be positioned in correspondence with the gap of the first layer (701) formed in the other direction (e.g., the left direction or the 9 o'clock direction in FIG. 23).

[0296] With respect to the core (721, 723, 725, 727) and adsorbent (731, 733), the description of the core (721, 723, 725, 727) and adsorbent (731, 733) described in FIG. 18 may be applied substantially the same way.
