Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] This utility model provides a double-thermal-break aluminum alloy exterior window profile, such as... Figure 1 As shown, the window includes a window frame and a window sash. The window sash includes an outer frame 1 and an inner frame 2 set on both sides of the double-glazed glass. A core frame 3 is also set between the outer frame 1 and the inner frame 2. A first window sash thermal insulation strip 4 is set between the core frame 3 and the outer frame 1. A second window sash thermal insulation strip 5 is set between the core frame 3 and the inner frame 2. The window frame includes an outer frame 6 and an inner frame 7. Both the outer frame 6 and the inner frame 7 are fixed to the wall. A core frame 8 is also set between the outer frame 6 and the inner frame 7. A first window frame thermal insulation strip 9 is set between the core frame 8 and the outer frame 6. A second window frame thermal insulation strip 10 is set between the core frame 8 and the inner frame 7. Furthermore, a first sealing strip 11 is provided between the outer frame 6 and the sash outer frame 1. One end of the first sealing strip 11 is fixed to the outer frame 6, and the other end can overlap with the sash outer frame 1. A second sealing strip 12 is provided between the inner frame 7 and the sash inner frame 2. One end of the second sealing strip 12 is fixed to the sash inner frame 2, and the other end can overlap with the inner frame 7. A multi-cavity sealing strip 13 is provided between the core frame 8 and the sash core frame 3. The multi-cavity sealing strip 13 includes a first sub-strip and a second sub-strip that can overlap with each other. The end of the first sub-strip away from the second sub-strip is connected to the first sash thermal insulation strip 4, the second sash thermal insulation strip 5, and the sash core frame 3. The end of the second sub-strip away from the first sub-strip is connected to the outer frame 6, the core frame 8, and the inner frame 7. It should be noted that, in this embodiment, as Figure 1As shown, a first window sash thermal break strip 4 is installed between the core frame 3 and the outer frame 1; a second window sash thermal break strip 5 is installed between the core frame 3 and the inner frame 2; a first window frame thermal break strip 9 is installed between the core frame 8 and the outer frame 6; and a second window frame thermal break strip 10 is installed between the core frame 8 and the inner frame 7. That is, two thermal break strips are installed both inside the window frame and inside the window sash to achieve a double-thermal-break design. Figure 1 When the window sash is closed, the first sealing strip 11 forms the first sealing structure between the window frame and the window sash, the second sealing strip 12 forms the second sealing structure, and the multi-cavity sealing strip 13 forms the third sealing structure. That is, three sealing structures are formed on both sides and inside the cavities between the window frame and the window sash. Combined with the double thermal break design, as shown... Figure 5 As shown, the heat transfer coefficient of the external window profile node provided in this embodiment is effectively reduced to 2.78W / m2•K. Compared with conventional aluminum alloy external windows, its thermal performance is improved by 20%, which reduces building energy consumption while increasing the temperature difference between the inside and outside of the window and reducing the occurrence of condensation on the inner surface of the window.

[0019] In one embodiment, such as Figures 1 to 4 As shown, both the outer frame 1 and the inner frame 2 of the sash are connected to the insulating glass via a tower-shaped sealing strip 15. A flexible gasket 14 is also provided between the core frame 3 and the insulating glass. The first sash thermal insulation strip 4, the second sash thermal insulation strip 5, the first window frame thermal insulation strip 9, and the second window frame thermal insulation strip 10 are all in the shape of an I-beam. The bottom of the first sash thermal insulation strip 4 and the second sash thermal insulation strip 5 is also provided with a connecting barb 501. The core frame 8 and the sash core frame 3 are also provided with a connecting groove 301 at their respective ends so that the two sub-strips of the multi-cavity sealing strip 13 can be connected to the core frame 8 and the sash core frame 3 respectively. A warm edge strip 16 is also provided between the ends of the two sub-glasses of the insulating glass. It should be noted that, in this embodiment, as Figure 1 and Figure 2 As shown, the fan core frame 3 and the core frame 8 have the same structure, and their connecting slots 301 are arranged facing towards each other, as shown. Figure 1 and Figure 3 As shown, the second window sash thermal break strip 5 has the same structure as the first window sash thermal break strip 4, and the connecting barbs of the two are arranged in opposite directions, as shown. Figure 1 and Figure 4 As shown, the first window frame thermal insulation strip 9 and the second window frame thermal insulation strip 10 have the same structure, which means that all components inside the aluminum alloy window profile have a standardized structure, which is convenient for factory production. Most structural components are repetitive, which reduces their production costs. In this embodiment, the thermal insulation strip and core frame 8 inside the window are standardized and designed for batch repetition, making their structure simpler and easier to manufacture. This reduces the cost of aluminum alloy windows while improving their thermal performance, making them easier to market.
