Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy door and window profiles, specifically a cold-resistant aluminum alloy door and window profile with a gradient heat insulation layer. Background Technology

[0002] Aluminum alloy door and window profiles refer to profiles with specific cross-sectional shapes made from aluminum alloy materials through processes such as extrusion and stretching. These profiles form the basis of major components such as aluminum alloy door and window frames and sashes. The quality of aluminum alloy profiles directly affects the strength, airtightness, watertightness, thermal insulation performance, and service life of doors and windows.

[0003] Currently, the existing aluminum alloy door and window profiles have a relatively simple structure, but when used in severe cold weather, they have poor cold resistance and cannot meet people's needs for heat insulation and cold resistance. Therefore, we propose a cold-resistant aluminum alloy door and window profile with a gradient heat insulation layer. Utility Model Content

[0004] The purpose of this utility model is to provide a cold-resistant aluminum alloy door and window profile with a gradient heat insulation layer, which has the advantages of a gradient heat insulation layer and good cold resistance. It solves the problem that the existing aluminum alloy door and window profiles have a relatively simple structure and poor cold resistance when used in severe cold weather, thus failing to meet people's needs for heat insulation and cold resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold-resistant aluminum alloy door and window profile with a gradient thermal insulation layer, comprising:

[0006] A five-cavity thermally broken aluminum frame profile, wherein the left and right ends of the five-cavity thermally broken aluminum frame profile are respectively provided with a first filling layer insulation cavity and an insulation cavity, and the middle cavity of the five-cavity thermally broken aluminum frame profile is provided with a PA66 insulation strip and a first insulation cotton.

[0007] The five-cavity thermally broken window frame aluminum profile that is used in conjunction with the five-cavity thermally broken outer frame aluminum profile has a second filling layer thermal insulation cavity at both the left and right ends of the five-cavity thermally broken window frame aluminum profile, and a second thermal insulation cotton is provided in the cavity at the left end of the five-cavity thermally broken window frame aluminum profile.

[0008] A thermal insulation coating is applied to the surface of the five-cavity thermally broken aluminum frame profile and the five-cavity thermally broken window frame aluminum profile, and a reflective coating is applied to the outer side of the thermal insulation coating.

[0009] Preferably, the upper end of the five-cavity thermally broken aluminum profile of the window frame is provided with triple-glazed, two-cavity Low-E glass, and the interior of the triple-glazed, two-cavity Low-E glass is provided with a vacuum cavity and an inert gas cavity from left to right.

[0010] Preferably, the inner side of the inert gas chamber is filled with argon gas.

[0011] Preferably, the filling material in the first filling layer insulation cavity is mineral fiber cotton, and the filling material in the second filling layer insulation cavity is phenolic foam.

[0012] Preferably, the heat insulation coating is made of fluorocarbon paint coating, and the reflective coating is made of alumina ceramic layer.

[0013] Preferably, the bottom of the five-cavity thermally broken aluminum frame profile is provided with reinforcing ribs.

[0014] Preferably, a first glass sealing strip is provided on the upper part of the left end of the five-cavity thermally broken aluminum frame profile, and a second glass sealing strip is provided on the lower part of the right end of the five-cavity thermally broken aluminum frame profile.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model reduces the heat radiation emitted from the surface of the profile to the external environment by setting a reflective coating. The heat insulation coating can maintain the internal temperature of the aluminum alloy door and window profile to a certain extent. It can form a dual gradient of heat reflection and barrier in combination with the reflective coating.

[0017] 2. This utility model, through the setting of a five-cavity thermally broken outer frame aluminum profile and a five-cavity thermally broken window frame aluminum profile, enables the aluminum alloy door and window profile to adopt a multi-cavity design, forming a multi-layer thermal insulation barrier. The setting of the first filling layer thermal insulation cavity, the thermal insulation void, and the second filling layer thermal insulation cavity further enhance the thermal insulation strength of the multi-layer thermal insulation barrier while forming it, providing a further gradient thermal insulation capability. Through the setting of PA66 thermal insulation strip, first insulation cotton, and second insulation cotton, the middle part of the aluminum alloy door and window profile can achieve a further gradient thermal insulation capability. This allows the aluminum alloy door and window profile to have multi-gradient thermal insulation while achieving good cold resistance, meeting people's needs for thermal insulation and cold resistance.

[0027] Example 1

[0028] Please see Figures 1-4 As shown, this utility model provides a technical solution: a cold-resistant aluminum alloy door and window profile with a gradient heat insulation layer, comprising:

[0029] Five-cavity thermally broken aluminum profile 1, with a first filling layer insulation cavity 101 and an insulation cavity 105 respectively provided at the left and right ends of the five-cavity thermally broken aluminum profile 1, and a PA66 insulation strip 106 and a first insulation cotton 102 provided in the middle cavity of the five-cavity thermally broken aluminum profile 1.

[0030] The five-cavity thermally broken aluminum frame 2 is used in conjunction with the five-cavity thermally broken aluminum frame 1. The left and right ends of the five-cavity thermally broken aluminum frame 2 are respectively provided with a second filling layer insulation cavity 201, and the cavity at the left end of the five-cavity thermally broken aluminum frame 2 is provided with a second insulation cotton 203.

[0031] A thermal insulation coating 4 is applied to the surface of the five-cavity thermally broken aluminum frame profile 1 and the five-cavity thermally broken window frame aluminum profile 2. A reflective coating 5 is applied to the outer side of the thermal insulation coating 4.

[0032] The filling material in the first filling layer insulation cavity 101 is mineral fiber cotton, the filling material in the second filling layer insulation cavity 201 is phenolic foam, the heat insulation coating 4 is fluorocarbon paint coating, the reflective coating 5 is alumina ceramic layer, and the bottom of the five-cavity thermally broken frame aluminum profile 1 is provided with reinforcing ribs 104.

[0033] This technical solution: By setting the reflective coating 5, the coating can reduce the heat radiation emitted from the surface of the profile to the external environment. By setting the heat insulation coating 4, the internal temperature of the aluminum alloy door and window profile can be kept constant to a certain extent. It can form a dual gradient of heat reflection and barrier in combination with the reflective coating 5. By setting the five-cavity thermally broken outer frame aluminum profile 1 and the five-cavity thermally broken window frame aluminum profile 2, the aluminum alloy door and window profile adopts a multi-cavity design to form a multi-layer heat insulation barrier. In the first filling layer heat insulation cavity 101, heat insulation cavity 105 and second filling layer heat insulation cavity 105, the heat insulation cavity 101 and heat insulation cavity 105 are respectively used to form a heat insulation barrier. The inclusion of a multi-layered insulation cavity 201 enhances the insulation strength of the aluminum alloy window and door profile while forming a multi-layered insulation barrier, providing further gradient insulation capabilities. The PA66 insulation strip 106, the first insulation cotton 102, and the second insulation cotton 203 further enhance the gradient insulation capabilities in the middle of the aluminum alloy window and door profile. This allows the profile to achieve good cold resistance while providing multi-gradient insulation, meeting people's needs for heat insulation and cold resistance.

[0034] It should be noted that the five-cavity thermally broken outer frame aluminum profile 1 and the five-cavity thermally broken window frame aluminum profile 2 used in this aluminum alloy door and window profile can be purchased directly from the market and are existing technologies, so they will not be described in detail here.

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the upper end of the five-cavity thermally broken aluminum profile 2 of the window frame is provided with triple-glazed two-cavity Low-E glass 3. The interior of the triple-glazed two-cavity Low-E glass 3 is provided with a vacuum cavity 301 and an inert gas cavity 302 from left to right. The inner side of the inert gas cavity 302 is filled with argon gas.

[0037] This technical solution: By setting up triple-glazed, two-cavity Low-E glass 3, and by setting up a vacuum cavity 301 and an inert gas cavity 302, a gradient thermal insulation design for the glass system can be achieved. In extremely cold regions, the vacuum cavity 301 and the inert gas cavity 302 can be combined to further reduce the thermal conductivity coefficient and improve the cold resistance of aluminum alloy doors and windows.
