warm edge spacer

Abstract

The invention provides a warm side parting strip and belongs to hollow glass interval profiles. The warm side parting strip is used for forming and keeping the interval space in hollow glass and has the extending longitudinal direction, the transverse width perpendicular to the longitudinal direction and the height perpendicular to the longitudinal direction and transverse direction. When an interval profile frame is in a mounted state, the inner wall of interval profile frame faces the interval space in the hollow glass in the height direction. A profile body is composed of a flat plastic strip and a U-shaped metal strip. A pair of folded edges is arranged at the top end of the U-shaped metal strips and provided with occlusion structures, and the flat plastic strip and the occlusion structures are combined to form the inner wall.

Description

technical field [0001] The invention relates to a hollow glass spacer, in particular to a warm edge spacer with a composite structure. Background technique [0002] The hollow glass unit has at least two pieces of glass, and a spacer frame is interposed in the middle. The spacer frame can be formed by connecting and combining multiple profiles through connectors, or can be bent from a whole piece of profile. A seal is formed between the two pieces of glass and the spacer frame to prevent air from entering the space, which requires that the spacer profile must be designed to prevent gas diffusion. At the same time, during the manufacturing process, the air will be sealed in the insulating glass. It is necessary to fill the profile with hygroscopic materials (such as molecular sieves) and open holes on the side of the profile facing the closed space to absorb the water vapor in the closed space. Keep dry to avoid moisture (dew point) inside the insulating glass when the tempe...

[0004] The second is the hollow glass warm edge spacer as disclosed in patent documents CN101044292A and CN205778263U, such as image 3 and Figure 4 As shown, it consists of a U-shaped stainless steel sheet, an adhesive layer evenly scraped on the inner wall of the U-shaped stainless steel sheet, and plastic profiles. The lower, left, and right sides of the plastic profile are respectively connected to the three sides of the U-shaped stainless steel sheet The inner wall of the façade is firmly bonded by the glue layer to form a whole hollow profile. The manufacturing process is also quite complicated. First, the steel sheet is bent into a U shape, then hot melt adhesive is applied, and finally it enters the steel-plastic co-extrusion mold for forming.

[0005] The thermal resistance improvement of the second type of warmer spacer is limited, because the thickness of the plastic material that meets the same structural strength is much larger than that of metal, resulting in a larger volume of the conductive belt

[0007] How to design a warm edge spacer with higher thermal resistance, easier cold rolling processing and sufficient strength has become a technical problem that those skilled in the art have been eager to solve but have never been successful.
