Description

Technical Field

[0001] This utility model relates to the field of glass door technology, and in particular to an energy-saving, heat-insulating, and noise-reducing glass door. Background Technology

[0002] In modern architecture, doors serve as connecting passageways between the interior and exterior spaces, and their performance directly impacts indoor comfort and energy consumption. Traditional glass doors, while offering excellent lighting and visual transparency, generally suffer from poor sound insulation and heat preservation. In cold winters, indoor heat easily escapes through glass doors, making it difficult to maintain indoor temperatures and increasing the energy consumption of heating equipment. Conversely, in hot summers, a large amount of outdoor heat enters the room, raising indoor temperatures and increasing the burden on air conditioning and other cooling equipment. This not only hinders energy conservation but also increases user costs. Furthermore, poor sound insulation allows external noise to easily penetrate the room, disrupting daily life and work. Therefore, we propose an energy-saving, heat-insulating, and noise-reducing glass door to address these issues. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 An energy-saving, heat-insulating, and noise-reducing glass door includes a door body 8. The material of the door body 8 can be selected according to different usage scenarios and architectural styles, such as wood, metal, etc.

[0030] A glass door frame 11 is installed on the door body 8. The glass door frame 11 is made of aluminum alloy. Aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, which can well ensure the structural stability and durability of the glass door. Its surface can be treated with anodizing to enhance its oxidation resistance and aesthetics.

[0031] A glass body 9 is installed inside the glass door frame 11. The glass door frame 11 is provided with aluminum foil 5, polyurethane foam board 2, carbon fiber mesh 3 and vacuum insulation board 6 at equal intervals inside. One end of the vacuum insulation board 6 is connected to one side inside the glass door frame 11, and the aluminum foil 5 is connected to the other side inside the glass door frame 11. The aluminum foil 5 has good reflective properties and can reflect heat and light, reducing heat transfer. Multiple openings 1 are provided at equal intervals on the aluminum foil 5. The openings 1 can further increase air circulation and buffer, and improve the noise reduction effect.

[0032] Polyurethane foam board 2 is an excellent thermal insulation material with an extremely low thermal conductivity, which can effectively prevent heat conduction and play a good role in thermal insulation. At the same time, it also has a certain sound absorption property, which can absorb some noise.

[0033] The carbon fiber mesh 3 has high strength and toughness, which can enhance the overall structural strength of the glass door frame 11. In addition, carbon fiber also has a certain degree of conductivity, which can play an anti-static role.

[0034] The vacuum insulation panel 6 is provided with an installation groove 7, which is filled with nano-silica aerogel felt 4. One end of the nano-silica aerogel felt 4 is covered with carbon fiber mesh 3. The vacuum insulation panel 6 is a high-efficiency insulation material. Its interior is in a vacuum state, which can minimize the transfer of heat.

[0035] The aluminum foil 5 has multiple openings 1 at equal intervals. A handle 10 is fixed on one side of the glass door frame 11. The glass door frame 11 is made of aluminum alloy. The nano-silica aerogel felt 4 has extremely low thermal conductivity and good sound absorption performance. It is a new type of high-efficiency heat preservation and noise reduction material.

[0036] One end of the nano-silicone aerogel felt 4 is covered with carbon fiber mesh 3, which allows heat and noise to be blocked and absorbed by multiple layers of materials during the transmission process, further improving the energy-saving, heat-insulating and noise-reducing effect.

[0037] The glass body 9 is made of tempered glass, which has good strength and safety. When it is broken by external force, it will break into small particles, reducing the harm to the human body. At the same time, tempered glass also has good heat resistance and cold resistance, and can adapt to different ambient temperatures.

[0038] In this utility model, during assembly:

[0039] 1. Material Preparation: Prepare all necessary materials according to the design requirements, including an aluminum alloy glass door frame 11, a tempered glass body 9, an aluminum foil 5 with openings 1, a polyurethane foam board 2, a carbon fiber mesh 3, a vacuum insulation board 6, a nano-silica aerogel felt 4, and a handle 10. When preparing materials, a strict quality inspection is required to ensure that the specifications and performance of the materials meet the design requirements. For example, check whether there are scratches, deformations, or other defects on the surface of the aluminum alloy glass door frame 11; check whether the thickness and transparency of the tempered glass body 9 meet the standards.

[0040] 2. Assemble the glass door frame: Inside the glass door frame 11, install aluminum foil 5, polyurethane foam board 2, carbon fiber mesh 3 and vacuum insulation board 6 in sequence from the inside to the outside. Connect one end of the vacuum insulation board 6 to one side inside the glass door frame 11 and the aluminum foil 5 to the other side. During the installation process, use a suitable adhesive to firmly bond each layer of material together to ensure a tight fit between the layers and avoid gaps that would affect the heat insulation and noise reduction effect. At the same time, pay attention to the installation sequence and position of each layer of material to ensure its symmetry and uniformity.

[0041] 3. Filling with nano-silica aerogel felt: Open an installation groove 7 on the vacuum insulation board 6 and fill the installation groove 7 with nano-silica aerogel felt 4 so that one end of the nano-silica aerogel felt 4 is attached to the carbon fiber mesh 3. When opening the installation groove 7, ensure that the size and depth of the groove meet the design requirements to ensure that the nano-silica aerogel felt 4 can be tightly filled in the groove. During the filling process, care should be taken to avoid damage to the nano-silica aerogel felt 4 to ensure its integrity and performance.

[0042] 4. Install the glass body: Install the glass body 9 into the glass door frame 11 and fix it. When installing the glass body 9, sealant strips and other sealing materials are needed to seal the gap between the glass and the door frame to prevent air and moisture from entering and improve the waterproof and sound insulation performance of the glass door. At the same time, it is necessary to ensure that the installation position of the glass body 9 is accurate and that the horizontal and verticality meet the requirements.

[0043] 5. Install handle: Fix handle 10 on one side of glass door frame 11. When installing handle 10, use appropriate screws or other connectors to firmly fix it to the door frame to ensure that the handle will not loosen during use. At the same time, adjust the installation height and angle of the handle to conform to ergonomic principles and make it convenient for users to use.

[0044] 6. Overall Installation: Install the assembled glass door onto door body 8 to complete the installation of the entire energy-saving, heat-insulating, and noise-reducing glass door. During the overall installation process, tools such as a level need to be used to adjust the horizontal and verticality of the glass door to ensure that the glass door is installed flat and firmly. At the same time, check whether the glass door opens and closes smoothly and whether the door lock and other accessories are working properly.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
