Description

Technical Field

[0001] This application relates to thermal insulation materials, and more particularly to transparent vacuum insulation panels and refrigeration and heat preservation devices. Background Technology

[0002] Vacuum insulation panels are composed of a core material and a highly airtight barrier membrane. The barrier membrane typically houses the vacuum insulation panel within a low-pressure containment space, where the panel's rigidity resists atmospheric pressure. Due to the low pressure and fewer air molecules within the containment space, and the core material's ability to impede molecular movement, heat transfer caused by air convection is effectively prevented, significantly reducing the thermal conductivity. Vacuum insulation panels are widely used in cold chain equipment, building exterior wall insulation, refrigerated containers, and medical insulated boxes. The main component of a vacuum insulation panel is the core material, with the barrier membrane positioned on both sides. The barrier membrane primarily serves to prevent water and air from entering, protecting the core material. Common core materials include granular, foam, fiber, and composite materials, and are typically not transparent. This opaque nature of the core material limits the application of vacuum insulation panels to products requiring transparency, such as wine cabinets and beverage coolers for product display.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Unless otherwise specified, the terminology used herein should be understood as having the meaning commonly used in the art. Therefore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. In case of any conflict, this specification shall prevail.

[0028] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this application can be purchased from the market or prepared by existing methods.

[0029] Existing vacuum insulation panels have a technical problem of being opaque.

[0030] The technical solution provided in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0031] In a first aspect, embodiments of this application provide a transparent vacuum insulation panel, the transparent vacuum insulation panel comprising:

[0032] The core material is a plate with a hollow structure, and the hollow structure is arrayed on the plate.

[0033] The bag body is made of a transparent barrier film, and a vacuum cavity for containing the core material is provided inside the bag body.

[0034] The core material is designed as a perforated panel. This perforation is not randomly distributed but neatly arranged in an array. This design helps to minimize material usage while maintaining structural strength, thus reducing the overall weight of the insulation panel. The perforated structure also effectively reduces heat conduction, as air (or a vacuum) is a poor conductor of heat. This structure makes it difficult for heat to transfer through the core material, thereby improving insulation performance. The bag body uses a transparent barrier film as the material. This film not only has good transparency but also effectively prevents the penetration of gas and water molecules, thus maintaining the vacuum state within the vacuum chamber. The transparency ensures that the insulation panel does not block light during application, making it particularly suitable for applications requiring both insulation and light transmission, such as architectural glass and display cases. The vacuum chamber inside the bag, which houses the core material, further reduces the possibility of heat conduction and convection, significantly improving the insulation effect. The presence of the vacuum chamber also allows for full utilization of the perforated structure of the core material, as the extremely low thermal conductivity of air in a vacuum further enhances the insulation performance. This type of transparent vacuum insulation panel has broad application prospects in many fields, such as architectural glass, display cabinets, and refrigerated display cabinets. It not only improves the aesthetics and practicality of the products, but also promotes the development of related industries.

[0035] It is easy to understand that the air pressure inside the vacuum chamber is very low. Under atmospheric pressure, the portion of the bag located in the hollow structure will deform inward. The plate can resist the pressure exerted on the bag by the atmosphere, preventing the bag from deforming excessively and maintaining the low air pressure state inside the vacuum chamber.

[0036] It is easy to understand that the main function of the transparent barrier film is to isolate the vacuum cavity from the outside world and block water and gas. Traditional barrier films typically include a barrier layer with strong barrier properties and a protective layer disposed on the surface of the barrier layer, and the barrier layer is usually made of a metallic material. In this application, to achieve the transparency of the transparent barrier film, the barrier layer can be made of a polymer material with strong barrier properties.

[0037] In this embodiment, a plate with a hollow structure is used as the core material. The hollow structure allows light to pass through, and the hollow structure is arrayed on the plate, making the core material transparent as a whole. At the same time, the bag body is also made of a transparent barrier film. Since both the core material and the bag body are transparent, the transparent vacuum insulation board is also transparent.

[0038] In some embodiments of this application, the hollow structure is any one of a rectangle, parallelogram, triangle, or hexagon.

[0039] It is easy to understand that rectangles, parallelograms, triangles, and hexagons can all be densely arranged to form a grid structure. The perforated structure should be arranged as densely as possible to increase the area ratio of the perforated structure on the core material, thereby increasing the light transmittance of the core material. This application embodiment achieves a transparent design for vacuum insulation panels by proposing a core material with a perforated structure of a specific shape. On the one hand, by selecting geometric shapes such as rectangles, parallelograms, triangles, and hexagons as perforated structures, not only are the design styles of the core material enriched, but the aesthetic and functional requirements of different application scenarios are also met. On the other hand, these geometric shapes have regular boundaries and internal spaces, which helps to minimize the use of materials while ensuring structural strength, thereby reducing the possibility of heat conduction and convection and improving insulation performance. On the other hand, by using a transparent barrier film as the bag material and combining it with these geometric perforated structures, the entire insulation panel maintains high-efficiency insulation performance while possessing good transparency.

[0040] In some embodiments of this application, the cutout structure is rectangular, and the cutout structure is distributed in a rectangular array on the plate.

[0041] It is easy to understand that setting the perforated structure as rectangular allows the core material to present a rectangular grid structure. This structure is simple in structure, easy to manufacture, and suitable products are readily available on the market. Firstly, the rectangular perforated structure not only simplifies the processing and reduces production costs but also improves the structural stability and strength of the core material. Simultaneously, the rectangular array distribution makes the perforated structure more uniform on the board, contributing to a more uniform insulation effect. Secondly, the rectangular perforated structure reduces the solid portion of the core material, thereby reducing the possibility of heat conduction. Furthermore, the rectangular array distribution makes the heat transfer path within the core material more complex, further improving insulation performance. Thirdly, the use of a transparent barrier film bag, combined with the rectangular perforated structure and rectangular array distribution, allows the entire insulation board to maintain high-efficiency insulation performance while possessing good transparency and aesthetics.

[0042] In some embodiments of this application, the width of the hollow structure is 5–15 mm; and / or,

[0043] The thickness of the plate is 3mm or more; and / or,

[0044] The spacing between adjacent hollow structures is 1 to 5 mm.

[0045] It is easy to understand that the width of the perforated structure and the thickness of the plate both affect the vacuum level of the transparent vacuum insulation panel. The air pressure inside the vacuum chamber is very low; under atmospheric pressure, the portion of the bag located within the perforated structure will inevitably deform inwards. Ideally, for the transparent vacuum insulation panel, the deformation of the bag should be limited. While the air pressure inside the vacuum chamber drops sufficiently, the transparent barrier films on both sides of the core material should not be forced together by atmospheric pressure, causing heat conduction and thus affecting the insulation effect of the transparent vacuum insulation panel. Practice shows that when the width of the perforated structure is between 5 and 15 mm and the thickness of the plate is greater than 3 mm, the deformation of the bag is acceptable, ensuring that the air pressure inside the transparent vacuum insulation panel is sufficiently low while preventing the transparent barrier films on both sides of the core material from sticking together. The perforated structure width is 3mm or more, which ensures the structural strength of the core material while reducing material usage and production costs. At the same time, an appropriate width also helps improve thermal insulation performance, as a wider perforated structure can more effectively reduce heat conduction. For example, the width of the perforated structure can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm. The plate thickness is 3mm or more, ensuring that the core material has sufficient strength and stability to resist the impact and vibration of the external environment. At the same time, a thicker plate also helps improve the overall rigidity and durability of the insulation board. For example, the plate thickness can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm. The spacing between adjacent perforated structures is 1–5 mm, which helps to achieve a more uniform heat insulation effect. Smaller spacing reduces the heat transfer path within the core material, thereby improving heat insulation performance. Simultaneously, appropriate spacing maintains the transparency and aesthetics of the core material. For example, the spacing between adjacent perforated structures can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm. By precisely controlling the width of the perforated structures, the thickness of the panel, and / or the spacing between adjacent perforated structures, the embodiments of this application achieve a vacuum insulation panel that maintains high-efficiency heat insulation performance while possessing good transparency and aesthetics. This design is particularly suitable for applications requiring simultaneous consideration of heat insulation, transparency, and aesthetics, such as architectural glass and display cabinets.

[0046] In some embodiments of this application, the material of the plate is a transparent material.

[0047] It is easy to understand that using a transparent material for the plate helps to increase the transparency of the transparent vacuum insulation plate.

[0048] In some embodiments of this application, the material of the plate is any one of polyethylene terephthalate, polymethyl methacrylate, polystyrene, polycarbonate, transparent MS plastic, and transparent nylon.

[0049] It's easy to understand that, on the one hand, all the above materials are transparent plastics with a certain mechanical strength, providing reliable support for the bag while maintaining transparency. Polyethylene terephthalate (PET) has advantages such as transparency, lightweight, high strength, high chemical resistance, barrier properties, and low price, and is widely used in packaging (e.g., beverage bottles, food packaging), construction (e.g., sound insulation materials, heat insulation materials), and electronics (e.g., capacitor films, flexible circuit boards). Acrylic, also known as plexiglass, has high light transmittance (up to 93%), good strength and abrasion resistance, impact resistance, good heat resistance, excellent chemical resistance, and low water absorption. Polystyrene has a light transmittance of up to 90%, is lightweight, and has strong water stability. Polycarbonate is a high-performance, tough, amorphous, and transparent thermoplastic polymer with high impact strength, dimensional stability, and good mechanical properties. Transparent MS plastic refers to a copolymer of 70% ethylene and 30% methyl methacrylate, with a light transmittance of up to 92%, good chemical stability, and abrasion resistance. Transparent nylon is an amorphous or microcrystalline thermoplastic nylon with a light transmittance of up to 90%, and it possesses properties such as oil resistance, corrosion resistance, wear resistance, and scratch resistance. Secondly, these materials all have excellent processing properties, such as ease of molding, cutting, and welding, making the manufacturing process of vacuum insulation panels more efficient and flexible. At the same time, these materials also have good dimensional and thermal stability, helping to ensure product quality and consistency. Thirdly, by selecting these materials, effective cost control is achieved while ensuring product performance. For example, PET and PS are less expensive than PC and PMMA, but still meet basic transparency and insulation performance requirements. This material selection strategy helps reduce production costs and improve the product's market competitiveness. Fourthly, the above materials have good environmental protection properties, such as being recyclable and biodegradable, promoting sustainable development.

[0050] In some embodiments of this application, the air pressure in the vacuum chamber is not higher than 1 Pa.

[0051] It is easy to understand that maintaining a vacuum chamber pressure no higher than 1 Pa minimizes heat convection within the transparent vacuum insulation panel. Lowering the vacuum chamber pressure to below 1 Pa significantly reduces collisions and conduction between gas molecules, thereby reducing the likelihood of heat conduction and convection. This low-pressure environment results in higher insulation efficiency for the vacuum insulation panel, better maintaining internal temperature stability. The low-pressure environment also helps reduce the penetration and corrosion of the core and bag materials by gas molecules, extending product lifespan and maintaining performance stability, which is particularly important for applications requiring long-term insulation performance. By achieving highly efficient insulation, the vacuum insulation panel of this embodiment can be applied to more scenarios with stringent temperature control requirements, such as refrigerated display cases, cryogenic laboratories, and spacecraft.

[0052] In some embodiments of this application, the transparent barrier film includes two opposing protective layers and at least one barrier layer disposed between the two protective layers.

[0053] The protective layer is made of a flexible, transparent polymer material, and the barrier layer is made of transparent silicone.

[0054] It is easy to understand that transparent silicone, while allowing light to pass through, also possesses excellent barrier properties against water and gas. The flexible transparent polymer material, as a protective layer, not only has good transparency and flexibility but also resists external environmental erosion, such as ultraviolet radiation and moisture, thereby extending the product's lifespan. The transparent silicone, as a barrier layer, has excellent barrier properties, effectively preventing the penetration of gas and water molecules, maintaining the vacuum state within the vacuum cavity, and thus improving the insulation effect. By combining the protective layer and the barrier layer, a multi-layered transparent barrier film is formed. This structure not only improves the overall performance of the material but also makes the product easier to process and customize, meeting the needs of different application scenarios. By selecting appropriate materials, the embodiments of this application achieve effective cost control while ensuring product performance. For example, flexible transparent polymer materials and transparent silicone are less expensive than other high-performance materials, yet still meet the basic requirements for transparency and barrier performance. In summary, by designing a multi-layered transparent barrier film and carefully selecting materials, a comprehensive improvement in product transparency, barrier properties, flexibility, and cost is achieved.

[0055] In some embodiments of this application, the material of the protective layer is any one of low-density polyethylene, polypropylene, and polyvinyl chloride.

[0056] It is easy to understand that all of the above materials can be prepared into flexible transparent plastics with certain mechanical strength and toughness. Low-density polyethylene (LDPE), also known as high-pressure polyethylene, is the lightest variety of polyethylene resin. It has good flexibility, extensibility, electrical insulation, transparency, and processability. It also has good chemical stability and is resistant to alkalis and common organic solvents. Polypropylene has good chemical resistance, heat resistance, electrical insulation, high mechanical strength, and wear resistance. It can also be modified through grafting, copolymerization, crosslinking, reinforcement, and filling to meet different needs. Some polypropylene products on the market have a light transmittance of over 90%. Polyvinyl chloride (PVC) is a thermoplastic resin polymerized from vinyl chloride monomer. It can be divided into rigid PVC and flexible PVC, with flexible PVC being suitable as the protective layer material described in this application. Flexible PVC has high strength and good light transmittance, air tightness, and water impermeability.

[0057] Secondly, embodiments of this application provide a refrigeration and heat preservation device, the device comprising the transparent vacuum insulation panel described in the first aspect.

[0058] Refrigeration and insulation devices are widely used in various fields, such as refrigerated display cases, refrigerators, cold storage, and cold chain logistics. They are crucial for maintaining low-temperature environments, preventing heat transfer, and preserving the freshness and quality of food, medicine, and other goods. This application's embodiments, by introducing the transparent vacuum insulation panel described in the first aspect, achieve technological breakthroughs and innovations in refrigeration and insulation devices in the following aspects: High-efficiency insulation: The transparent vacuum insulation panel utilizes the low pressure under vacuum conditions to reduce heat conduction and convection, resulting in highly efficient insulation performance.

[0059] For example, the refrigeration and insulation device includes: refrigerator, freezer, refrigerated display case, cold storage, refrigerated truck, ice maker, air conditioner, refrigeration compressor, refrigeration dryer, and refrigeration fan.

[0060] Refrigerators and Freezers: Using transparent vacuum insulation panels reduces heat transfer inside refrigerators and freezers, improving energy efficiency. The transparent design also allows users to clearly see the items inside, facilitating retrieval and management. Refrigerated Display Cases: Transparent vacuum insulation panels can be used on the glass doors or side walls of refrigerated display cases to maintain a low internal temperature while showcasing goods to customers.

Ice Makers: Transparent vacuum insulation panels can be used on the ice storage boxes or water tanks of ice makers to reduce heat transfer and improve ice-making efficiency. Air Conditioners: Although air conditioners themselves do not directly use transparent vacuum insulation panels, these panels can be used to insulate pipes and components within the air conditioning system, reducing energy loss and improving system efficiency. Refrigeration compressors: Although refrigeration compressors themselves do not directly use transparent vacuum insulation panels, these panels can be used to insulate the pipes and components around the compressor, reducing energy loss. Refrigeration dryers: The gas storage tanks or piping sections of refrigeration dryers can use transparent vacuum insulation panels to reduce heat transfer and moisture condensation.
