Bridge-cutoff aluminum alloy energy-saving window

Abstract

Broken bridge aluminum alloy energy-saving windows, the window frame includes frame profiles and middle frame profiles, and the opening window includes sash profiles. The frame profiles and middle frame profiles are all four-cavity structures. The four-cavity structure includes the first The chamber, the second chamber, the third chamber and the fourth chamber, the fourth chambers in each frame profile communicate with each other, and the left and right ends of the fourth chamber of the middle frame profile communicate with the frame ventilation channel; A lower air inlet is opened on the outer side wall of the fourth chamber of the frame profile at the bottom of the window frame, and a middle air inlet is opened on the outer side wall of the fourth chamber of the middle frame profile, which is located outside the fourth chamber of the frame profile at the top of the window frame There is an upper air outlet on the wall; the sash profile is a three-cavity structure, and the three-cavity structure includes an inner chamber, a middle chamber and an outer chamber arranged in sequence from the inside to the outside. Through the natural ventilation structure, the invention can prevent the outer side of the frame profile and the middle frame profile from being heated by sunlight to collect heat and accelerate the heat transfer to the room, thereby improving the energy-saving effect of doors and windows.

Description

technical field [0001] The invention relates to building doors and windows, in particular to an aluminum alloy energy-saving window with broken bridges. Background technique [0002] Energy saving of doors and windows is the key to building energy saving. Doors and windows are not only sensitive parts of energy gain and loss, but also related to lighting, ventilation, sound insulation and facade shape. This puts forward higher requirements for energy saving of doors and windows. The energy saving treatment is mainly to improve materials Excellent thermal insulation performance and improve the airtight performance of doors and windows. [0003] The thermal insulation performance of existing aluminum alloy windows with broken bridges in my country has been unable to compare with plastic steel windows, but the aging resistance and wind pressure resistance of plastic steel profiles are inferior to aluminum alloy profiles with broken bridges. With my country's higher and higher ...
