Description

Technical Field

[0001] The utility model relates to the technical field of thermal-break aluminum alloy doors and windows, in particular to a thermal-break aluminum alloy door and window with a K value of 1.4. Background Art

[0002] Doors and windows are important components of building facades, and their structural design directly affects the building's energy consumption performance and indoor comfort. However, the existing door and window technology still has some shortcomings that cannot be ignored. These problems are mainly concentrated in the following aspects:

[0003] 1. Thermal conduction problem of thermally-insulated aluminum alloy: Thermally-insulated aluminum alloy doors and windows reduce heat conduction by adding insulation strips to aluminum alloy profiles. This design reduces the heat conduction of the metal frame to a certain extent. However, due to the presence of cavities in the thermally-insulated aluminum alloy profiles, these cavities will cause energy loss through air convection. In the prior art, these cavities are usually filled to prevent convection and thus reduce heat loss. However, the material that fills the cavity itself will introduce new heat conduction channels, which will lead to higher heat loss. This solution increases heat conduction while avoiding convection, so that the overall insulation effect fails to be significantly improved, and it also causes material waste.

[0004] 2. Thermal radiation of glass: In modern door and window structures, the glass part usually occupies more than 80% of the entire door and window opening. The thermal performance of glass is crucial to the overall thermal insulation effect of doors and windows. Ordinary white glass commonly found on the market has a high thermal emissivity. About 84% of the heat can be radiated into the room or outdoors through the white glass, which means that most of the heat energy can be radiated and exchanged through the glass. When the air-conditioning system is operating, the temperature difference between indoors and outdoors will cause a lot of energy loss through the high thermal emissivity of the glass. This situation not only increases the energy consumption of the building, but also leads to significant energy waste.

[0005] 3. Material deformation and sealing failure: During long-term use, doors and windows may suffer performance degradation due to material deformation or sealing failure. Especially when doors and windows are subjected to external forces such as wind pressure, improper design or insufficient material strength can easily cause deformation or joint failure, leading to poor sealing. In this case, the thermal insulation and air tightness of doors and windows will be seriously affected. Although metal materials have high strength, performance cannot be improved simply by increasing wall thickness, because in some cases, simply increasing material thickness cannot effectively improve the wind pressure resistance of doors and windows, but may cause a waste of resources.
