Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to a casement aluminum alloy door and window with heat insulation and double-layer sealing. Background Technology

[0002] Traditional doors and windows often suffer from problems such as heat conduction between glass and metal frame (e.g., "cold bridge effect"), condensation inside the glass cavity, and reduced air tightness due to aging of sealing strips. These issues not only affect indoor insulation but also cause damage to glass edges or sealing structures due to long-term dampness, shortening the lifespan of doors and windows. To address this, a casement aluminum alloy door and window with thermal bridge insulation and double-layer sealing is provided. Utility Model Content

[0003] The purpose of this invention is to provide a high-insulation and sealing door and window structure that solves the problems of poor heat insulation, easy condensation, and unsustainable sealing of traditional doors and windows by layering to block heat conduction, strengthening sealing, and providing buffer protection.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A casement aluminum alloy door and window with thermal bridge and double-layer sealing includes a window frame, a window sash and hardware components. The window frame and window sash are composed of an outdoor aluminum alloy substrate, an indoor aluminum alloy substrate and a thermal bridge in the middle. The window frame and window sash are respectively provided with an outer sealing layer and an inner sealing layer. The glass of the window sash is divided into three layers, and a double glass sealing strip is provided in the glass mounting groove of the window sash.

[0006] Furthermore, the three layers of glass are an outer glass layer, a middle glass layer, and an inner glass layer. The outer glass layer is made of wired glass, the middle glass layer is made of Low-E glass which can reflect far-infrared rays and reduce indoor heat loss and solar radiation heat entry, and the inner glass layer is made of tempered glass.

[0007] Furthermore, an inert gas, such as argon or krypton, is filled between the three layers of glass to reduce gas convection between the glass layers and improve the heat insulation and sound insulation performance of the doors and windows.

[0008] Furthermore, the edges of the triple-layered glass are equipped with warm edge spacers made of a composite material with low thermal conductivity and containing molecular sieves that can adsorb water vapor in the glass cavity and prevent condensation.

[0009] Furthermore, the double-layer glass sealing strip is divided into a hard strip for fixing the outer side of the glass and a soft strip for buffering and airtight sealing the inner side.

[0010] Furthermore, the space between the glass and the window sash is filled with polyurethane foam to block heat conduction between the glass and the aluminum alloy substrate.

[0011] Furthermore, the aluminum alloy substrates of both the window frame and the window sash adopt a multi-cavity structure, and the cavities are filled with polyurethane insulation cotton to reduce the thermal conductivity of the metal substrate.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] Significantly reduces heat transfer efficiency, minimizes the "cold bridge effect," and improves the overall window insulation performance; adsorbs moisture to prevent condensation, and double-sealed for enhanced airtightness and extended seal life; elastic materials buffer stress, reducing glass breakage and substrate deformation, and extending overall service life.

[0017] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-2 As shown, this utility model provides a casement aluminum alloy door and window with thermal bridge and double-layer sealing, including window frame 1, window sash 2 and hardware components. The window frame 1 and window sash 2 are composed of an outdoor aluminum alloy substrate 10, an indoor aluminum alloy substrate 11 and a thermal bridge 3 in the middle. The window frame 1 and window sash 2 are respectively provided with an outer sealing layer and an inner sealing layer. The glass of the window sash 2 is divided into three layers, and a double glass sealing strip is provided in the glass mounting groove of the window sash 2.

[0019] This casement aluminum alloy door and window with thermal bridge 3 and double-layer sealing is mainly composed of window frame 1, window sash 2, and hardware components. Window frame 1 and window sash 2 are composed of an outdoor aluminum alloy substrate 10, an indoor aluminum alloy substrate 11, and a thermal bridge 3 in between. The thermal bridge 3 effectively blocks the direct transfer of heat between the indoor and outdoor areas through the metal substrate, significantly improving the thermal insulation performance of the door and window. Simultaneously, window frame 1 and window sash 2 are respectively equipped with an outer sealing layer and an inner sealing layer, forming double protection. The outer sealing layer can prevent rainwater and windblown sand from penetrating from the outside to the inside, while the inner sealing layer... The sealing layer further enhances airtightness and reduces energy loss caused by indoor and outdoor air exchange. Window sash 2 adopts a triple-glazed design. The air layer between the multiple glass layers can effectively block noise transmission and improve sound insulation performance. At the same time, it can also slow down the heat transfer rate and enhance heat preservation. The double glass sealing strips set in the glass mounting groove of window sash 2 can not only tightly fix the glass, but also form two sealing lines between the glass and window sash 2. This prevents the sealing performance from decreasing due to aging or local damage of the sealing strips, and further ensures the stability of the glass installation and the overall sealing reliability.

[0020] The three layers of glass are an outer glass 6, a middle glass 5, and an inner glass 4. The outer glass 6 is made of wired glass, the middle glass 5 is Low-E glass that can reflect far-infrared rays and reduce indoor heat loss and solar radiation heat entry, and the inner glass 4 is made of tempered glass.

[0021] The triple-glazed structure of the doors and windows consists of an outer layer of wired glass, a middle layer of Low-E glass, and an inner layer of tempered glass, from the outside in. The outer layer of wired glass has metal wires embedded inside, which allows it to maintain its overall shape even if it breaks due to external impact, preventing shards from flying and improving safety. The middle layer of Low-E glass has a special low-emissivity film that efficiently reflects far-infrared rays. In winter, it reflects far-infrared heat radiation from indoor heating back into the room, reducing heat loss and lowering heating energy consumption. In summer, it blocks far-infrared heat from solar radiation from entering the room, slowing down the rise in room temperature and achieving two-way heat insulation and energy saving. The inner layer of tempered glass is reinforced so that even if it breaks accidentally, it will form small, blunt-edged particles, significantly reducing the risk of injury to people, while also enhancing the structural strength of the entire window and ensuring long-term stability.

[0022] The space between the three panes of glass is filled with an inert gas, such as argon or krypton, to reduce gas convection between the glass panes and improve the heat insulation and sound insulation performance of the doors and windows.

[0023] The cavity between the three panes of glass in the doors and windows is filled with inert gases such as argon or krypton. Because the thermal conductivity of argon and krypton is much lower than that of ordinary air, filling them effectively inhibits gas convection between the glass layers, reduces heat transfer through gas flow, and thus improves the overall heat insulation performance of the window. In winter, it can slow down the loss of indoor heat to the outside, and in summer, it can block the conduction of high outdoor temperatures to the inside. At the same time, the molecular structure of inert gases is more compact and moves more slowly, which can more effectively block the propagation of sound waves in the gas, reduce the transmission of external noise to the room, and significantly enhance the sound insulation effect. In addition, these gases are chemically stable and do not easily react with glass or sealing materials, so they can remain in a filled state for a long time to ensure the durability of heat insulation and sound insulation performance.

[0024] The edges of the triple-layered glass are equipped with warm edge spacers 7, which are made of a composite material with low thermal conductivity and contain molecular sieves to adsorb water vapor in the glass cavity and prevent condensation.

[0025] The triple-glazed windows feature a warm edge spacer 7 made of a low thermal conductivity composite material. This low thermal conductivity material effectively reduces the heat transfer efficiency of the glass edges, minimizing the "cold bridge" phenomenon (where the edge becomes too cold due to rapid heat conduction) that is common with traditional metal spacers 7. This improves the overall thermal insulation performance of the window. Meanwhile, the internal molecular sieve acts like a miniature "desiccant," continuously absorbing residual moisture or moisture that seeps in due to aging seals within the glass cavity. This keeps the interlayer environment dry, preventing condensation (condensation) on the inner surface of the glass caused by temperature differences. This ensures both the light transmittance and aesthetics of the glass, while also preventing long-term dampness from corroding the sealing strips or glass edges, extending the overall sealing reliability and lifespan of the window.

[0026] The double-layer glass sealing strip is divided into a hard strip 9 for fixing the outer side of the glass and a soft strip 8 for buffering and airtight sealing the inner side.

[0027] The double-layer glass sealing strip consists of an outer and an inner layer. The outer layer is a hard strip 9, and the inner layer is a soft strip 8. The outer hard strip 9 is made of a harder material and has a more stable structure. It mainly serves to fix the outer side of the glass. By closely adhering to the edge of the glass and the window frame 1, it forms a rigid support, preventing the glass from shifting or falling off due to daily opening and closing or external impacts, thus ensuring the stability of the glass installation. The inner soft strip 8 is soft and has excellent elasticity. On the one hand, it acts as a buffer between the glass and the window frame 1, absorbing the vibration or minor impact energy when opening and closing the window, avoiding the risk of breakage caused by direct hard contact between the glass and the metal frame. On the other hand, the soft strip 8, through its own elastic deformation, closely adheres to the contact surface between the glass and the window frame 1, forming a continuous airtight barrier, effectively blocking the penetration of indoor and outdoor air and moisture, and enhancing the overall sealing performance of the window. The synergistic effect of the two strips not only improves the safety of the glass installation but also ensures long-term sealing performance.

[0028] The space between the glass and the window sash 2 is filled with polyurethane foam to block heat conduction between the glass and the aluminum alloy substrate.

[0029] The gap between the glass and the window sash 2 is filled with polyurethane foam with extremely low thermal conductivity and a porous structure, forming a highly efficient heat-blocking layer between the glass and the aluminum alloy substrate. By physically blocking the direct heat conduction path between the two, the efficiency of heat transfer from the high-temperature side to the low-temperature side is reduced, thereby significantly improving the overall heat insulation performance of the window. This reduces the loss of indoor heating heat to the outside through the metal substrate in winter and blocks the conduction of outdoor high temperature to the inside through the substrate in summer, helping to maintain a stable indoor temperature and reduce air conditioning or heating energy consumption. At the same time, the elastic properties of the foam can also buffer the rigid contact between the glass and the metal frame, alleviate the stress concentration of the glass caused by thermal expansion and contraction or daily vibration, and reduce the risk of cracking.

[0030] Both the aluminum alloy substrates of the window frame 1 and the window sash 2 adopt a multi-cavity structure, and the cavities are filled with polyurethane insulation cotton to reduce the thermal conductivity of the metal substrate.

[0031] Both the aluminum alloy substrates of window frame 1 and window sash 2 adopt a multi-cavity structure design, with each independent cavity filled with polyurethane insulation cotton. The multi-cavity layered structure first reduces the direct transfer of heat within the substrate by separating the continuous heat conduction paths inside the metal; while the filled polyurethane insulation cotton, with its extremely low thermal conductivity, further blocks the heat conduction of the metal substrate itself. The synergistic effect of the two significantly reduces the overall heat conduction efficiency of the aluminum alloy substrate, reducing the loss of indoor heat to the outside through the metal frame in winter and blocking the conduction of outdoor high temperatures to the inside through the frame in summer, significantly improving the thermal insulation performance of the entire window; at the same time, the multi-cavity structure also enhances the substrate's resistance to deformation, and the elastic properties of the polyurethane insulation cotton can buffer the stress caused by thermal expansion and contraction or external impact, extending the service life of window frame 1 and window sash 2.
