Aluminum alloy profile with double heat insulation broken bridge structures

Abstract

The invention discloses an aluminum alloy profile with double heat insulation broken bridge structures. The aluminum alloy profile comprises an outer aluminum alloy profile A, a middle aluminum alloy profile B and an inner aluminum alloy profile C, wherein the outer aluminum alloy profile A and the middle aluminum alloy profile B are separated by a strip penetrating type heat insulation strip or an adhesive filling type heat insulation adhesive, the middle aluminum alloy profile B and the inner aluminum alloy profile C are separated by an adhesive filling type heat insulation adhesive or a strip penetrating type heat insulation strip, and then the aluminum alloy profile with the double heat insulation broken bridge structures is formed. The aluminum alloy profile with the double heat insulation broken bridge structures has the advantages that the aluminum alloy profile is separated into three parts by the strip penetrating type heat insulation strips or the adhesive filling type heat insulation adhesives, so the direct contact between the aluminum alloy profiles with good heat conduction property is avoided, heat insulation broken bridges are formed at double sides, and are completely isolated, the integral heat insulation effect of the aluminum alloy profile is optimized, and the energy consumption of air conditioners and the like is decreased.

Description

technical field [0001] The invention relates to an aluminum alloy profile structure for doors and windows, in particular to an aluminum alloy profile with a double-channel heat-insulating broken bridge structure. Background technique [0002] In the field of door and window manufacturing, the application of doors and windows of various materials such as aluminum alloy, plastic or plastic steel to fixed buildings has been very common. Among them, the door and window frames supported by aluminum alloy profiles are the most widely used because they have considerable strength and aesthetics, but also have the advantages of light weight and low price. [0003] The aluminum alloy itself is an aluminum alloy material, which has good thermal conductivity. Therefore, it is necessary to fully optimize its structure when using it as an efficient thermal insulation door and window frame, so that the aluminum alloy door and window frame can have good thermal insulation performance while...

Problems solved by technology

[0004] 1. The heat insulation technology of PA66 nylon strips in the middle of the aluminum on both sides imported from Europe; the length of the heat insulation strips is between 10mm-35mm, and the commonly used heat insulation strips are 14.8mm. If the heat insulation requirements are high, it is necessary to use more than 35mm of heat insulation Strips, but the strength of the composite profiles is severely reduced, and the shear resistance is reduced, causing hidden safety hazards for doors and windows, and the longer the insulation strips, the higher the cost;

[0005] 2. The heat insulation technology of aluminum glue injection broken bridge imported from the United States. The heat insulation openings of this technology are divided into A-type notch, B-type notch, C-type notch and D-type notch. No more than 20mm, it is difficult to improve the heat insulation effect;
