Description

Technical Field

[0001] The present invention relates to the technical field of glass manufacturing, in particular to a vacuum glass with a multi-layer composite structure and a preparation process thereof. Background Art

[0002] Vacuum glass is a highly efficient, energy-saving glass. Early versions consisted of two layers of glass with a vacuum drawn between them. This layer's extremely low thermal conductivity reduces heat transfer, resulting in excellent thermal and sound insulation. However, its development and use have limitations. Its sound insulation is limited, and it lacks the ability to effectively control high-frequency noise. This makes it difficult to meet the demands of acoustically demanding environments. Its temperature regulation performance also needs improvement. While the vacuum layer effectively prevents convective heat transfer, the supporting structure causes some heat to be lost through conduction through the solids, impacting the overall insulation and preventing it from properly regulating the glass's temperature. Summary of the Invention

[0003] The purpose of the present invention is to provide a vacuum glass with a multi-layer composite structure and a preparation process thereof, so as to solve the problem raised in the above background technology that the sound insulation effect of traditional vacuum glass is not ideal for some high-frequency noise, it is difficult to meet the needs of places with high requirements for acoustic environment, and the temperature regulation performance needs to be improved. Although the vacuum layer can effectively prevent convective heat transfer, the support will cause part of the heat to be lost through solid conduction, affecting the overall thermal insulation effect and failing to regulate the temperature of the glass well.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a vacuum glass with a multi-layer composite structure, comprising a honeycomb metal core frame, a plurality of graphene aerogel fillings, a plurality of curved microchannels, a vertical channel 1, a vertical channel 2 and a vacuum glass body, wherein the honeycomb metal core frame is arranged inside the vacuum glass body, and the plurality of curved microchannels all penetrate the pores of the honeycomb metal core frame, and the pores on the honeycomb metal core frame are all provided with graphene aerogel fillings at positions staggered from the plurality of curved microchannels, one end of the plurality of curved microchannels are all connected to a connector 1, the other end of the plurality of curved microchannels are all connected to a connector 2, and the plurality of connectors 1 are all connected to the vertical channel 1. On the top, multiple connecting heads 2 are all connected to the vertical channel 2, and the vertical channel 1 and the vertical channel 2 are respectively arranged inside the vacuum glass body at the left and right ends of the rear side of the honeycomb metal core frame, and a reinforcement plate is installed on the left side of the vacuum glass body. The top and bottom of the vertical channel 2 are respectively connected to the connecting transverse channel 1 and the connecting transverse channel 2, and the connecting transverse channel 1 and the connecting transverse channel 2 respectively pass through the upper and lower parts of the reinforcement plate and are connected to the main channel. Switch valves are installed on the connecting transverse channel 1 and the connecting transverse channel 2 near the main channel, the upper and lower parts of the left side of the main channel are connected to the inlet channel, and the middle part of the left side of the main channel is connected to the outlet channel.

[0005] As a preferred technical solution of the present invention, the front center left and center right sides of the honeycomb metal core frame are each provided with inner panels 1, each of which is equidistantly provided with multiple circulation holes 2. The back center left, center right, and center sides of the honeycomb metal core frame are respectively provided with inner panels 4, 2, and 3, each of which is equidistantly provided with multiple circulation holes 1. The circulation holes 2 on inner panel 1 and the circulation holes 1 on inner panels 2, 3, and 4 are interlaced with the curved microchannels. When the fluid circulates in the curved microchannel, it can exchange heat with the internal and external environments of the vacuum glass through these circulation holes, thereby improving the temperature regulation efficiency. For example, in winter, the heating fluid releases heat into the room through the circulation holes, and in summer, the cooling fluid absorbs the indoor heat. The inner panels three and four are hollow inside and filled with sound insulation cotton, which cooperates with other structures to provide sound insulation. When sound propagates to the inner panels, the sound insulation cotton absorbs sound energy through the porous structure. At the same time, the blocking and reflection effects of the inner panels, combined with the graphene aerogel filling, weaken the sound propagation from different frequency bands and paths, thereby significantly improving the overall sound insulation effect of the vacuum glass.

[0006] As a preferred technical solution of the present invention, the plurality of curved microchannels penetrate the two inner plates 1, inner plate 4, inner plate 2 and inner plate 3 at positions staggered between the plurality of circulation holes 2 and the plurality of circulation holes 1.

[0007] As a preferred technical solution of the present invention, the plurality of curved microchannels are multiple and equidistantly wound on a honeycomb metal core frame.

[0008] As a preferred technical solution of the present invention, an electrochromic film layer is provided on the outer surface of the vacuum glass body.

[0009] As a preferred technical solution of the present invention, a plurality of connecting posts are equidistantly installed on the rear portion of the honeycomb metal core frame, and the plurality of connecting posts are equidistantly installed on the inner rear side of the vacuum glass body.

[0010] As a preferred technical solution of the present invention, the interiors of the inner panels three and four are hollow, and the hollow positions of the inner panels three and four are partially filled with sound insulation cotton.

[0011] The present invention provides a process for preparing a vacuum glass having a multi-layer composite structure, comprising the following steps: Step 1: Material preparation: Select high-transmittance, high-strength float glass as the substrate, cut it according to the required vacuum glass size, and prepare the low-melting-point glass frit, getter, and support materials for sealing; Step 2: Glass cleaning and pretreatment: Place the cut glass substrate in an ultrasonic cleaning machine and use deionized water and an appropriate amount of detergent to remove impurities such as oil and dust on the surface. Then dry it and chemically treat the glass surface by soaking it in a dilute hydrochloric acid solution to increase the activity of the glass surface and improve the quality of subsequent coating and sealing. Step 3: Coating: Magnetron sputtering technology is used to coat multi-layer thin films, anti-reflection films, and low-emissivity films on the glass substrate. The thickness uniformity and performance stability of the film are guaranteed by precisely controlling the sputtering parameters, sputtering power, time, and gas flow rate. Step 4. Install the getter: Install the getter at the edge or appropriate position inside the vacuum glass to absorb the trace gas that may be released during use and maintain the vacuum degree.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By integrating a honeycomb metal core, graphene aerogel filling, and curved microchannels, a "passive insulation and active temperature control" composite system is constructed. Different from the single thermal insulation mode of traditional vacuum glass, the graphene aerogel blocks heat conduction, the honeycomb structure inhibits convection, and the curved microchannel circulating fluid actively regulates the temperature, achieving efficient thermal insulation and precise temperature control. By using graphene aerogel filling, sound insulation cotton in inner panels three and four, and the porous structure of the honeycomb metal core frame, a multi-level, multi-band sound insulation system is formed. From microscopic pore sound absorption to macroscopic structural reflection, it covers the entire frequency band of sound insulation and breaks through the bottleneck of traditional vacuum glass sound insulation performance.

[0013] By equidistantly winding the curved microchannels and staggering them with multiple circulation holes 1 and multiple circulation holes 2, in conjunction with connecting cross channel 1, connecting cross channel 2, the main channel and the switch valve, an efficient fluid circulation network is formed. By precisely controlling the fluid path and flow, the temperature of the vacuum glass can be uniformly adjusted across the entire area. Compared with the traditional single-channel design, the temperature control efficiency is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-10 The present invention provides a vacuum glass with a multi-layer composite structure and a preparation process thereof, comprising a honeycomb metal core frame 3, a plurality of graphene aerogel fillings 4, a plurality of curved microchannels 6, a vertical channel 1 7, a vertical channel 2 8 and a vacuum glass body 1, wherein the honeycomb metal core frame 3 is arranged inside the vacuum glass body 1, the plurality of curved microchannels 6 all penetrate the pores of the honeycomb metal core frame 3, the pores on the honeycomb metal core frame 3 are all provided with graphene aerogel fillings 4 at positions staggered from the plurality of curved microchannels 6, one end of the plurality of curved microchannels 6 are all connected to a connector 1 9, the other end of the plurality of curved microchannels 6 are all connected to a connector 2 10, the plurality of connectors 1 9 are all connected to the vertical channel 1 7, the plurality of connectors 2 10 They are both connected to the vertical channel 2 8. The vertical channel 1 7 and the vertical channel 2 8 are respectively arranged inside the vacuum glass body 1 at the left and right ends of the rear side of the honeycomb metal core frame 3. A reinforcement plate 2 is installed on the left side of the vacuum glass body 1. The top and bottom of the vertical channel 2 8 are respectively connected to the connecting transverse channel 1 11 and the connecting transverse channel 2 12. The connecting transverse channel 1 11 and the connecting transverse channel 2 12 pass through the upper and lower parts of the reinforcement plate 2 respectively and are connected to the main channel 15. On-off valves 16 are installed on the connecting transverse channel 1 11 and the connecting transverse channel 2 12 near the main channel 15. The upper and lower parts of the left side of the main channel 15 are connected to the inlet channel 17, and the middle part of the left side of the main channel 15 is connected to the outlet channel 18; Using the vacuum glass body 1 as the core structure, the interior is evacuated to create a low-pressure environment, significantly reducing heat conduction and convection heat transfer, achieving basic thermal and sound insulation. A reinforcement plate 2 is installed on the left side of the vacuum glass body 1 to share external pressure, enhancing the overall impact and pressure resistance of the glass, preventing deformation or breakage of the vacuum glass body 1 due to external forces, and ensuring the stability of the internal vacuum cavity. A honeycomb metal core frame 3, with a regular honeycomb-shaped pore distribution, provides a high-strength support structure, evenly distributing external pressure and maintaining the shape of the vacuum cavity. Graphene aerogel 4 is filled in these pores at staggered locations of the curved microchannels 6. Its extremely low thermal conductivity of 0.013-0.025 W / (m·K) and high porosity further block heat conduction paths. Furthermore, the aerogel's porous structure scatters and absorbs sound, enhancing sound insulation. Active thermal management can be performed by circulating a circulating fluid such as a coolant or a heating liquid through a plurality of curved microchannels 6 wound equidistantly on the honeycomb metal core frame 3. The plurality of curved microchannels 6 are equidistantly wound and pass through the pores of the honeycomb metal core frame 3. One end of the plurality of curved microchannels 6 is connected to the vertical channel 1 7 through a connector 1 9, and the other end is connected to the vertical channel 2 8 through a connector 2 10. During operation, fluid such as coolant or heating liquid flows from the inlet channel 17 into the main channel 15, is controlled by the switch valve 16, enters the vertical channel 2 8 through the connecting transverse channel 1 11, and is then diverted to each curved microchannel 6. After heat exchange with the honeycomb metal core frame 3 and the surrounding environment in the channel, it flows out from the outlet channel 18 through the vertical channel 1 7 and the connecting transverse channel 2 12. The connecting transverse channel 1 11 and the connecting transverse channel 2 12 pass through the reinforcement plate 2 and connect the vertical channel 2 8 with the main channel 15, forming a key transmission path for fluid circulation. The main channel 15 serves as a main pipeline, gathering the fluid input from the inlet channel 17 and exporting the fluid that has completed heat exchange through the outlet channel 18. The switch valve 16 can flexibly control the fluid flow rate and flow direction to achieve temperature control.

[0018] The front center left and center right sides of the honeycomb metal core frame 3 are each provided with an inner plate 19, and a plurality of circulation holes 14 are evenly spaced on each of the two inner plates 19. The rear center left, center right, and center sides of the honeycomb metal core frame 3 are each provided with an inner plate 4 22, an inner plate 20, and an inner plate 3 21, respectively. The inner plate 4 22, the inner plate 20, and the inner plate 3 21 are each evenly spaced with a plurality of circulation holes 13. Circulation holes 2 14 on inner panel 1 19 and circulation holes 13 on inner panels 2 20, 3 21, and 4 22 are interlaced with the curved microchannels 6. As fluid circulates within the curved microchannels 6, it can exchange heat with the surrounding environment inside and outside the vacuum glazing through these circulation holes, improving temperature regulation efficiency. For example, in winter, the heating fluid releases heat into the room through the circulation holes, while in summer, the cooling fluid absorbs indoor heat. Inner panels 3 21 and 4 22 are hollow and filled with soundproofing cotton, which works in conjunction with other structures to provide sound insulation. When sound propagates to the inner panels, the soundproofing cotton absorbs the sound energy through its porous structure. Simultaneously, the blocking and reflection effects of the inner panels, combined with the graphene aerogel filling 4, weaken sound transmission at different frequency bands and paths, significantly improving the overall sound insulation of the vacuum glazing.

[0019] The plurality of curved microchannels 6 penetrate the two inner plates 19, the inner plate 4 22, the inner plate 20 and the inner plate 3 21 at positions staggered between the plurality of circulation holes 2 14 and the plurality of circulation holes 1 13.

[0020] The plurality of curved microchannels 6 are wound around the honeycomb metal core frame 3 in a plurality and at equal intervals.

[0021] The outer surface of the vacuum glass body 1 is coated with an electrochromic film 23. Applying different voltages causes ions within the film to migrate and change its optical properties. As the voltage changes, the film switches between a transparent state and a dark state, adjusting light transmittance and thus controlling the amount of solar radiation entering the room, achieving intelligent dimming and energy-saving effects.

[0022] The rear portion of the honeycomb metal core frame 3 is evenly spaced with multiple connecting posts 5. These are evenly spaced and installed on the rear side of the interior of the vacuum glass body 1. The connecting posts 5 evenly spaced on the rear side of the honeycomb metal core frame 3 have one end fixed to the honeycomb metal core frame 3 and the other end connected to the rear side of the interior of the vacuum glass body 1. Under external pressure, the connecting posts 5 assist the honeycomb metal core frame 3 in dispersing the pressure, enhancing the internal structural stability of the vacuum glass and preventing displacement or deformation of the honeycomb metal core frame 3. The interiors of the inner panels 3 21 and 4 22 are hollow, and these hollow areas are partially filled with sound insulation cotton. The sound insulation cotton absorbs sound energy through its porous structure, while also providing the inner panels with both blocking and reflecting properties.

[0023] In the present invention, the vacuum glass body 1 is used as the core structure, and the interior is evacuated to form a low-pressure environment, which greatly weakens the heat conduction and convection heat transfer of the gas, thereby achieving basic thermal insulation and sound insulation performance. The reinforcement plate 2 is installed on the left side of the vacuum glass body 1 to share the external pressure, enhance the overall impact and pressure resistance of the glass, prevent the vacuum glass body 1 from deformation or damage due to external forces, and ensure the stability of the internal vacuum cavity. The honeycomb metal core frame 3 is distributed with regular honeycomb pores to provide a high-strength support structure, evenly disperse external pressure, and maintain the shape of the vacuum cavity. In the pores, the positions of the staggered curved microchannels 6 are filled with graphene aerogel 4. Its extremely low thermal conductivity of 0.013-0.025W / (m·K) and high porosity are used to further block the heat conduction path. At the same time, the porous structure of the aerogel has a scattering and absorption effect on sound, thereby improving the sound insulation performance. Active thermal management can be performed by circulating a circulating fluid such as a coolant or a heating liquid through a plurality of curved microchannels 6 wound equidistantly on the honeycomb metal core frame 3. The plurality of curved microchannels 6 are equidistantly wound and pass through the pores of the honeycomb metal core frame 3. One end of the plurality of curved microchannels 6 is connected to the vertical channel 1 7 through a connector 1 9, and the other end is connected to the vertical channel 2 8 through a connector 2 10. During operation, fluid such as coolant or heating liquid flows from the inlet channel 17 into the main channel 15, is controlled by the switch valve 16, enters the vertical channel 2 8 through the connecting transverse channel 1 11, and is then diverted to each curved microchannel 6. After heat exchange with the honeycomb metal core frame 3 and the surrounding environment in the channel, it flows out from the outlet channel 18 through the vertical channel 1 7 and the connecting transverse channel 2 12. The connecting transverse channel 1 11 and the connecting transverse channel 2 12 pass through the reinforcement plate 2 and connect the vertical channel 2 8 with the main channel 15, forming a key transmission path for fluid circulation. The main channel 15 serves as a main pipeline, gathering the fluid input from the inlet channel 17 and exporting the fluid that has completed heat exchange through the outlet channel 18. The switch valve 16 can flexibly control the fluid flow rate and flow direction to achieve temperature control.

[0024] Circulation holes 2 (14) on inner panel 1 (19) and circulation holes 1 (13) on inner panels 2 (20), 3 (21), and 4 (22) are interlaced with curved microchannels 6. As fluid circulates within the curved microchannels 6, it can exchange heat with the surrounding environment inside and outside the vacuum glazing through these circulation holes, improving temperature regulation efficiency. For example, in winter, the heating fluid releases heat into the room through the circulation holes, while in summer, the cooling fluid absorbs indoor heat. Inner panels 3 (21) and 4 (22) are hollow and filled with soundproofing cotton, which works in conjunction with other structures to provide sound insulation. When sound propagates to the inner panels, the soundproofing cotton absorbs the sound energy through its porous structure. Simultaneously, the blocking and reflection effects of the inner panels, combined with the graphene aerogel filling (4), weaken sound transmission at different frequency bands and paths, significantly improving the overall sound insulation of the vacuum glazing.
