[0028] In view of this, the present application provides a hollow glass that can achieve better shading and sound insulation effects and can ensure privacy, and is suitable for buildings with high requirements for environmental control.

[0029] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a hollow glass 100 in one embodiment of the present application.

[0030] The embodiment of the present application provides a hollow glass 100, which comprises a first glass 10, a second glass 20 and a third glass 30 arranged in sequence and in layers, and further comprises a middle frame 40 arranged between the second glass 20 and the third glass 30.

[0031] The second glass 20, the third glass 30 and the middle frame 40 enclose the hollow cavity 401, the hollow cavity 401 is provided with a gas, as a gas layer, the gas layer can be used as a heat insulation layer, the overall heat insulation performance of the glass is increased, heat conduction is reduced, the middle frame 40 can provide a certain structural support, and the distance between the second glass 20 and the third glass 30 is maintained, and the inward suction or outward bulging phenomenon is prevented.

[0032] The first glass 10 is sound insulation glass, the second glass 20 is low-e coated glass, and the third glass 30 is colored glass.

[0033] As can be seen from the above, the hollow glass 100 provided by the embodiment of the application comprises the first glass 10, the second glass 20 and the third glass 30 which are sequentially and laminatedly arranged, the hollow glass 100 further comprises the middle frame 40 arranged between the second glass 20 and the third glass 30, the second glass 20, the third glass 30 and the middle frame 40 enclose the hollow cavity 401, the hollow cavity 401 is provided with a gas, the first glass 10 is sound insulation glass, the second glass 20 is low-e coated glass, and the third glass 30 is colored glass, so that better sun-shading, sound insulation and heat insulation effects can be achieved through the first glass 10, the second glass 20 and the hollow cavity 401, and the privacy can be ensured through the third glass 30, and the hollow glass 100 is suitable for buildings with high requirements for environmental control.

[0034] Optionally, the middle frame 40 can be an aluminum frame.

[0035] Please refer to Figure 1 In some embodiments, the first glass 10 comprises the sound insulation film 11 and the outer glass 12, and the sound insulation film 11 is located between the outer glass 12 and the first glass 10.

[0036] By adopting the above scheme, the sound insulation effect of the first glass 10 can be better, and the first glass 10 can have higher strength through the outer glass 12.

[0037] Optionally, the outer glass can be super white glass.

[0038] Please refer to Figure 1 In some embodiments, the first glass 10 comprises the power generation glass 13, and the power generation glass 13 is located between the outer glass 12 and the second glass 20.

[0039] By adopting the above scheme, the power generation glass 13 can provide sustainable energy supply for the building while the first glass 10 achieves better sound insulation effect.

[0040] It can be understood that the power generation glass 13 can convert solar energy into electric energy to provide sustainable energy supply for the building.

[0041] It should be noted that the first glass 10 faces the outdoor, so that the power generation glass 13 can convert solar energy into electrical energy without being blocked by the colored glass.

[0042] Optionally, two sound insulation films 11 are arranged, and the power generation glass 13 is located between the two sound insulation films 11.

[0043] In this way, better sound insulation effect can be achieved through the two sound insulation films 11, and the power generation glass 13 can convert solar energy into electrical energy.

[0044] In the embodiment, the power generation glass 13 includes a cadmium telluride solar cell.

[0045] In this way, the cadmium telluride thin film can be used as a photoelectric conversion layer, which has a spectral response that matches the ground solar spectrum distribution very well, can efficiently convert sunlight into electrical energy, and can maintain high power generation efficiency even in weak light environment, suitable for different light conditions in different regions and seasons, has strong actual power generation capacity, and is a clean energy, which can reduce the dependence on fossil fuels, reduce carbon emissions, and meet the requirements of sustainable development.

[0046] It should be noted that the power generation glass 13 can be customized in terms of light transmittance, color pattern, etc. according to the needs of building design, to meet the demand for building appearance style.

[0047] Optionally, the cadmium telluride solar cell can be a 3.2mm cadmium telluride solar cell with 60% light transmittance.

[0048] It can be understood that the power generation glass 13 can be connected to an energy storage battery or an electrical component such as a lamp.

[0049] Please refer to Figure 1 In some embodiments, the thickness of the outer glass 12 is 6mm-10mm, such as 6mm, 8mm or 10mm, etc.

[0050] By adopting the above scheme, the outer glass 12 can be more solid than ordinary glass, and the fragments are larger and the edges are blunter when broken, having high hardness and impact resistance, high safety, reducing the risk of injury to personnel, and also having certain heat insulation and sound insulation effects.

[0051] Please refer to Figure 1 In some embodiments, the sound insulation film 11 is a PVB (Polyvinyl Butyral) film or an EVA (Ethylene-vinyl Acetate Copolymer) film.

[0052] By adopting the above scheme, the sound insulation film 11 can have better sound insulation effect and lower cost, and is convenient to manufacture.

[0053] Optionally, the soundproofing interlayer 11 is a photovoltaic PVB interlayer.

[0054] In this way, the photovoltaic PVB interlayer is a high-performance encapsulation material mainly used in the manufacture of solar photovoltaic modules. This interlayer can be tightly bonded to the outer glass 12, the power-generating glass 13 and the second glass 20 through its excellent properties such as high light transmittance, high adhesion and good weather resistance, and can play a buffering role when the outer glass 12, the power-generating glass 13 and the second glass 20 are impacted. Even if they are broken, the fragments will be adhered by the photovoltaic PVB interlayer in the middle, preventing the fragments from flying and causing injury, thereby improving safety. At the same time, it can provide multiple functions such as electrical insulation, mechanical protection and anti-ultraviolet for cadmium telluride solar cells.

[0055] For reference Figure 1 In some embodiments, the second glass 20 is a three-silver-coated glass.

[0056] By using the above scheme, the second glass 20 can effectively reflect infrared and ultraviolet rays, reduce energy consumption, provide good thermal insulation performance, improve the energy efficiency of buildings, and reduce the demand for heating and air conditioning.

[0057] It should be noted that the three-silver-coated glass (also known as three-silver-toughened glass) is a high-performance low-emissivity (Low-E) glass. Its coating can reflect part of the solar radiation, reduce the heat entering the room, and at the same time allow visible light to pass through, which helps to reduce air conditioning energy consumption and improve indoor comfort. The three-silver-coated glass can be fully tempered glass or semi-tempered glass.

[0058] The three-silver-coated glass can be made by vacuum magnetron sputtering coating technology. The main coating machine is provided with multiple sputtering chambers, different target materials and process gases are selected in each sputtering chamber, and a nanoscale silver layer and a protective layer can be coated on the surface of the glass. The coating layer has the characteristics of high transmittance of visible light and high reflectivity of mid-infrared light. The production line mainly consists of glass feeding, cleaning, drying, coating, and unloading. The three-silver film is a low-reflectance / middle color system, and the solar heat gain coefficient is 0.37.

[0059] Optionally, the thickness of the second glass 20 is 6mm or 8mm.

[0060] The manufacturing steps of the first glass 10 and the second glass 20 mainly include material preparation, assembly, lamination, inspection, etc., which can be done on an automatic production line or manually.

[0061] First, prepare the materials.

[0062] Cadmium telluride solar cell: This is the core power generation component, which is made by depositing multiple layers of thin film materials on conductive glass.

[0063] Ultra-white glass: It has low self-explosion rate, high light transmittance and good permeability, making it an ideal packaging material.

[0064] Photovoltaic PVB film: High light transmittance and high bonding force, used for bonding cadmium telluride solar cells and ultra-white glass, providing electrical insulation and mechanical protection.

[0065] Secondly, assembly.

[0066] Clean the glass: Ensure that the surface of the ultra-white glass is free of dust, oil and other contaminants to avoid affecting the packaging quality.

[0067] Lay the photovoltaic PVB film: Lay the photovoltaic PVB film on a piece of ultra-white glass, ensuring no bubbles or wrinkles.

[0068] Place the cadmium telluride solar cell: Gently place the cadmium telluride solar cell on the photovoltaic PVB film, keeping it centered to avoid displacement.

[0069] Next, laminating.

[0070] Cover the three-silver-coated glass: Carefully place the three-silver-coated glass on top of the cadmium telluride solar cell, forming a "sandwich" structure.

[0071] Heat and press: Use a high-pressure kettle to heat and press the "sandwich" structure, usually at a temperature of 130-140°C, a pressure of about 10-12 atmospheres, and a time adjusted according to the size.

[0072] Cool and solidify: After pressing, let the entire structure cool naturally to room temperature, ensuring that the photovoltaic PVB film is completely solidified and forms a tight bond.

[0073] Finally, inspection.

[0074] Visual inspection: Check the packaged glass for bubbles, impurities or structural deformation.

[0075] Performance testing: Measure the photoelectric conversion efficiency, current and voltage of the module to ensure compliance with standard requirements.

[0076] Weather resistance testing: Conduct moisture resistance, ultraviolet resistance and temperature difference resistance testing to ensure reliability in actual environments.

[0078] By adopting the above scheme, the line of sight can be blocked to a certain extent, good light adjustment and shading functions are provided, better privacy protection is provided, the appearance of the building can be enhanced, and the indoor design is coordinated, the deep yellow color tone can absorb solar energy to a certain extent, and reduce the light and heat entering the indoor.

[0080] Optionally, the third glass 30 can be made by the following method: the pretreated glass is placed on the conveying table by manual or automatic sheet table, and then sent to the cleaning machine for cleaning and drying, and then enters the printing machine, the screen printing plate prepared in advance is placed on the upper surface of the glass by the positioning device, the glaze (environment-friendly water-based ink) is poured on the screen printing plate, and the pattern is printed on the surface of the glass by the operation of the scraper; then the printed glass is sent to the tunnel type drying machine through the conveying table for drying, and then the dried glass is manually placed on the glass rack and sent to the tempering furnace for tempering. The parameters of the equipment can be: total air pressure 0.5-0.9Mpa, scraper air pressure 0.4-0.8Mpa, oil knife air pressure 0.4-0.8Mpa, drying temperature 110-230℃, conveying speed 2-6m / min.

[0081] Please refer to Figure 1 In some embodiments, argon gas is arranged in the hollow cavity 401.

[0082] By adopting the above scheme, the heat preservation and insulation performance of the hollow glass 100 can be significantly improved, and the U value can be effectively reduced.

[0083] It can be understood that argon is an inert gas, and its thermal conductivity is low.

[0084] It should be noted that the U value is a measure of the heat conduction capacity of a material, which represents the ability of heat passing through per unit area, and the unit is W / m2·K.

[0085] Optionally, the thickness of the hollow cavity 401 along the arrangement direction of the second glass 20 and the third glass 30 is 12mm.

[0086] Please refer to Figure 1The hollow glass 100 provided by the embodiment of the present application comprises a first glass 10, a second glass 20 and a third glass 30 arranged in sequence and in layers, and further comprises a middle frame 40 arranged between the second glass 20 and the third glass 30, the second glass 20, the third glass 30 and the middle frame 40 enclose a hollow cavity 401, argon is arranged in the hollow cavity 401, the first glass 10 is sound insulation glass, the second glass 20 is three-silver coated glass, the thickness of the second glass 20 is 8 mm, the third glass 30 is deep yellow full-plate colored glaze glass, the thickness of the third glass 30 is 10 mm, and the thickness of the hollow cavity 401 along the arrangement direction of the second glass 20 and the third glass 30 is 12 mm.

[0087] The first glass 10 comprises a sound insulation film 11, an outer glass 12 and a power generation glass 13, the thickness of the outer glass 12 is 8 mm, the sound insulation film 11 is arranged between the outer glass 12 and the first glass 10, two sound insulation films 11 are arranged, the power generation glass 13 is arranged between the two sound insulation films 11, the power generation glass 13 is a cadmium telluride solar cell, and the sound insulation film 11 is a PVB film.

[0088] As can be seen from the above, the hollow glass 100 provided by the embodiment of the present application can achieve better sun-shading, sound insulation and heat insulation effects through the first glass 10, the second glass 20 and the hollow cavity 401, and can ensure privacy through the third glass 30, and is suitable for buildings with high requirements for environmental control.

[0089] The hollow glass 100 provided by the embodiment of the present application fully considers the advantages of thermal performance, power generation capacity, aesthetics and privacy, can achieve ultra-low sun-shading effect, improve safety, ensure privacy and aesthetics, can not only generate green energy, but also improve the energy efficiency of buildings, is suitable for new green buildings, and is also suitable for energy-saving reconstruction of existing buildings.

[0090] It should be noted that the solar heat gain coefficient is an index for measuring the blocking ability of glass to solar radiation. The lower the solar heat gain coefficient, the stronger the ability of the glass to block solar heat, thereby reducing the increase of indoor temperature and air conditioning energy consumption. The calculation of the solar heat gain coefficient usually involves multiple factors, including the type, coating, color and overall structure of the glass.

[0091] There are several key factors that affect the solar heat gain coefficient in the hollow glass 100 provided by the embodiments of the present application:

[0092] 1. Triple silver-coated glass: This type of glass typically has a lower solar heat gain coefficient because its low-emissivity coating effectively reflects some of the solar radiation. The specific solar heat gain coefficient depends on the characteristics of the coating, and the solar heat gain coefficient of triple silver-coated glass is 0.37.

[0093] 2. Deep yellow full-coverage enamel glass: This type of glass can absorb and reflect a certain proportion of sunlight, thereby reducing the solar heat gain coefficient. The deep yellow color may further reduce the solar heat gain coefficient, but the specific value needs to be determined according to the specific hue and saturation of the enamel.

[0094] 3. Soundproof glass and air layer: The presence of these layers not only improves the thermal insulation performance, but also may have an impact on the solar heat gain coefficient. In particular, the air layer as a thermal insulation layer helps to reduce the overall solar heat gain coefficient.

[0095] The overall solar heat gain coefficient is the product of the solar heat gain coefficients of each layer or is calculated according to a certain formula. The solar heat gain coefficient of the triple silver-coated glass 12 is 0.37, and the solar heat gain coefficient of the deep yellow full-coverage enamel glass is assumed to be 0.5 (the actual value may be different), then the overall solar heat gain coefficient can be roughly estimated as 0.175, and the actual solar heat gain coefficient needs to be determined through more detailed optical performance tests and calculations.

[0096] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
