Description

[0002] At present, when doors and windows are assembled, profile assembly is used to form a window frame for fixing a glass plate, and the glass plate and the window frame together form an integrated door and window. Commonly used door and window profiles are usually made of aluminum alloy or plastic steel material, and the profile is generally processed by melting raw materials, mold extrusion and straightening. In related technologies, the heat-insulating door and window in modern buildings generally realizes the heat-insulating function of the door and window by setting special glasses such as coated heat-insulating glass and vacuum heat-insulating glass. The heat-insulating performance of the window frame part of the heat-insulating door and window affects the overall heat-insulating performance of the door and window.

[0003] Chinese Patent No. CN 112922499 B was authorized on July 29, 2022, and discloses a combined heat-insulating door and window profile and a preparation method thereof. The profile comprises a support framework, the cross section of the support framework is a hollow rectangular frame, a through groove extending along the length direction of the support framework is formed on one side wall of the support framework, an enclosed frame is arranged inside the support framework, each outer side wall of the enclosed frame is tightly abutted against one inner side wall of the support framework, a plurality of enclosed ends are arranged in the enclosed frame, adjacent two enclosed ends form a group, the enclosed ends in the same group jointly form a sealed space in the enclosed frame, the sealed space is pumped to a negative pressure, a connecting end is arranged at the bottom of the outer wall of the support framework, and a glass fixing end is arranged on the side wall of the support framework. The technical solution has the following disadvantages: 1. The support framework is in a monolithic structure, and after installation, the outdoor temperature is easily conducted to the inside through the metal support framework, which causes a large amount of heat transfer under the hot outdoor environment and affects the heat-insulating effect; 2. The compatibility of the profile in the indoor part (the inner environment) with the environmental temperature change is low, so that the profile in the indoor part is easily affected by the temperature of the profile in the outdoor part (the outer environment), and the heat-insulating performance of the profile is further reduced.

[0004] In summary, the window frame profile is easily affected by the outer environment, which leads to low heat-insulating performance for the inner environment. SUMMARY

[0005] The present application is to overcome the problem that the profile is easily affected by the outer environment, which leads to low heat-insulating performance for the inner environment, and provides a high-performance heat-insulating aluminum alloy profile which can efficiently insulate heat and improve the temperature adaptability of the profile for the inner environment.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions:
