Technical Field
[0001] This utility model relates to the field of aluminum alloy technology, and in particular to a thermally broken aluminum alloy casement door and window. Background Technology
[0002] In the field of building doors and windows, thermally broken aluminum alloy casement doors and windows are widely used because they combine the high strength of aluminum alloy with the thermal insulation of thermally broken structure. Traditional thermally broken aluminum alloy casement windows and doors generally suffer from insufficient thermal insulation performance in practical use. Due to the high thermal conductivity of aluminum alloy, the temperature difference between indoors and outdoors easily leads to heat conduction through the window and door frames, causing rapid heat loss from the interior or intrusion from the exterior. This not only increases air conditioning energy consumption but also causes condensation to form on the surface of the window and door frames. While some thermally broken aluminum alloy windows and doors in the current technology have simple thermal break strips, they lack a systematic hot and cold air isolation structure, failing to effectively block the heat transfer path. Furthermore, the condensation generated during heat exchange is difficult to drain and tends to accumulate inside the window and door cavity, affecting not only the sealing and lifespan of the windows and doors but also potentially causing mold growth. Therefore, these problems need to be addressed. Utility Model Content

The first cold air duct 12, the second cold air duct 13 and the third cold air duct 14 are connected to facilitate the drainage of condensate generated during the exchange with indoor hot air through the guide channel; and an isolation strip 26 is slidably installed at the front end of the second cold air duct 13 to prevent outdoor impurities and other substances from entering the outer support 7; and a guide channel is provided in the inner cavity of the outer support 7, which runs through the first cold air duct 12, the second cold air duct 13, the third cold air duct 14 and the bottom end of the outer support 7.
[0014] In this invention, a first heat insulation strip 15 is slidably installed between the third hot air slot 11 of the inner support 6 and the third cold air slot 14 of the outer support 7. The first heat insulation strip 15 helps to prevent indoor hot air from directly conducting heat to the outside through the aluminum alloy frame and also serves to connect the inner support 6 and the outer support 7. A second heat insulation strip 16 is slidably installed on the upper end of the first heat insulation strip 15. A heat insulation block 17 is slidably installed on the upper end of the second heat insulation strip 16. A heat insulation platform 18 is slidably installed on the upper end of the heat insulation block 17. A fixed platform 22 is slidably installed on the upper end of the heat insulation platform 18.

[0015] Working principle: In the use of this utility model, after the first double-glazed glass 3 is installed through the thermally broken aluminum alloy bracket 1, the casement window 2 is installed in conjunction with the sliding groove 4 and the hinge platform 5 and then put into use. If a screen needs to be added later, it can be installed through the expansion groove 8. Since the indoor temperature will be higher than the outdoor temperature due to biological activity, the indoor temperature is conducted to the first hot air groove 9, the second hot air groove 10 and the third hot air groove 11 through the thermal conductivity of the aluminum alloy of the inner bracket 6. Furthermore, due to the thermal conductivity of the aluminum alloy of the outer bracket 7, the temperature of the first cold air groove 12, the second cold air groove 13 and the third cold air groove 14 is lower than that of the air grooves opened by the inner bracket 6. The insulating strip 26 installed on the outer bracket 7 will reduce the temperature difference between the second cold air groove 13 and the third cold air groove 14 and the outside. Because the inner support 6 and the outer support 7 are connected by a first thermal insulation strip 15, a second thermal insulation strip 16, a thermal insulation block 17, a thermal insulation platform 18, an outer clamping strip 19, a third thermal insulation strip 20, an inner clamping strip 21, a fixing platform 22, a protective rubber strip 24, an auxiliary support 25, and two second glass panes 23, the temperature of the air groove opened in the inner support 6 will be conducted to the outer support 7 very slowly. When the higher temperature of the inner support 6 is conducted to the outer support 7, because the temperature of the air groove opened in the outer support 7 is lower, water droplets will condense in the air groove opened in the outer support 7 due to the temperature difference. Then, the water droplets will flow out through the guide channel opened in the air groove of the outer support 7. This will slow down the rapid loss of indoor temperature and ensure the cleanliness of the thermally broken aluminum alloy support 1 and the casement window 2.
