Window frame profile with heat insulation broken bridge and sealing fins

Abstract

The invention provides a window frame profile with a heat insulation broken bridge and sealing fins. The window frame profile comprises a window frame outer frame, the frame heat insulation broken bridge and a window frame inner frame. The window frame profile is characterized in that the rear sealing fin is arranged on the rear side of the window frame profile and located on the right of the rear side of the window frame outer frame, and a heat insulation plate is arranged on the right side face of the rear sealing fin. The window frame profile and a matched window sash profile are used for a window, after a window sash is closed, a sealing piece on a sash outer frame of the window sash profile makes contact with the window frame outer frame, a sealing strip on the window frame inner frame makes contact with a sash inner frame of the window sash profile, a sealing body on the window sash profile makes contact with the rear sealing fin, and air between the window sash profile and the window frame profile is sealed and divided into two parts; and air between the frame heat insulation broken bridge and window frame glass and air between the frame heat insulation broken bridge and a wall are each divided into two parts by a sealing plate on the frame heat insulation broken bridge. The sash outer frame and the window frame outer frame cannot exchange heat with the sash inner frame and the window frame inner frame in an air convection mode, and the heat insulation effect of the window can be greatly improved.

Description

technical field [0001] The invention relates to a profile of a window, in particular to a window frame profile with a heat-insulating break bridge and a sealing fin. Cut off the air convection heat transfer path between the window frame profile and the sash profile. Background technique [0002] A window generally includes a window frame and a sash; and a window frame generally includes an upper horizontal frame, a lower horizontal frame, a left mullion, a right vertical frame, and a middle upper horizontal frame, and the middle upper horizontal frame is located at the upper middle of the window frame; some Also included is the middle mullion (or mullion). The sash generally includes an upper frame, a lower frame, a left frame, a right frame and glass. The sealing condition of the existing windows is not ideal, resulting in poor heat insulation and sound insulation effects, and outdoor dust easily enters the room and pollutes the indoor air. For example, when a window inc...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome that the existing windows with aluminum alloy profiles with heat-insulating broken bridges cannot cut off the path of air convection heat transfer between profiles, and cannot cut off the heat-insulating broken bridge and the wall. The path of air convection heat transfer, the path of air convection heat transfer between the heat insulation break bridge and the glass cannot be cut off, resulting in unsatisfactory heat insulation effect, and a window frame profile with heat insulation break bridge and sealing fins is provided
