Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a thermally broken aluminum alloy door and window with excellent thermal insulation properties. Background Technology

[0002] Aluminum alloy, as the core material for door and window manufacturing, is widely used in the construction field due to its unique physical properties and process adaptability. Among them, aluminum alloy has the advantages of high tensile strength and light weight, which reduces the load pressure of doors and windows on the building structure, making it especially suitable for high-rise buildings. In addition, it has the advantages of weather resistance and durability.

[0003] However, it also has obvious drawbacks. Aluminum alloy has an extremely high thermal conductivity, especially in the hot summer. Even with the addition of thermal break strips, it cannot provide good insulation, causing the inside of the window to be heated and raise the indoor temperature. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A thermally broken aluminum alloy door and window with excellent thermal insulation properties includes a frame mechanism. The frame mechanism includes two profiles arranged opposite each other, two thermal break strips connected between the two profiles, a metal foil installed inside the thermal break strips, a protrusion integrally formed with the profiles, and a slope provided on one side wall of the profiles.

[0007] By adopting the above technical solution, the narrow and deep heat insulation cavity can reduce the contact area between sunlight and the outdoor surface of the profile, thereby reducing the temperature rise of the profile. Then, the two heat insulation strips work together to reduce the transfer of high temperature. Here, the heat insulation strips work with the metal foil to form a sandwich structure of "heat insulation-reflection-heat insulation", which enhances the ability to reflect heat radiation. Through the multi-layer composite design, the thermal conductivity coefficient (U value) is reduced, effectively improving the heat insulation effect of this product.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the profile is integrally formed with multiple extensions, the multiple extensions are grouped in pairs, and the two extensions in each group are arranged in a figure-eight shape, and a groove is formed between the two extensions in each group.

[0009] In a preferred embodiment, the present invention can be further configured such that: two protruding strips are embedded inside the heat insulation strip, the two protruding strips are respectively attached to the top and bottom of the metal foil, and the protruding strips are interference-fitted inside the slot.

[0010] In a preferred embodiment, the present invention can be further configured such that a heat insulation cavity is formed between two slopes, the heat insulation cavity being narrow and deep.

[0011] In a preferred embodiment, the present invention can be further configured such that: an aerogel felt is embedded on one side of the profile, and the aerogel felt is located inside the heat insulation cavity.

[0012] In a preferred embodiment, this invention can be further configured such that a paraffin-based composite material is embedded on the other side of the profile, and the vertical cross-section of the paraffin-based composite material is L-shaped.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the narrow and deep heat insulation cavity can reduce the contact area between sunlight and the outdoor surface of the profile, thereby reducing the temperature rise of the profile. Then, the two heat insulation strips work together to reduce the transfer of high temperature. Here, the heat insulation strips work together with the metal foil to form a sandwich structure of "heat insulation-reflection-heat insulation", which enhances the ability to reflect heat radiation. Through the multi-layer composite design, the thermal conductivity coefficient (U value) is reduced, effectively improving the heat insulation effect of this product.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a thermally broken aluminum alloy door and window with excellent thermal insulation properties.

[0031] Example 1:

[0032] Combination Figure 1-5 As shown, the present invention provides a thermally broken aluminum alloy door and window with excellent thermal insulation properties, including a frame mechanism 100. The frame mechanism 100 includes two profiles 110 arranged opposite each other, two thermal break strips 120 connected between the two profiles 110, a metal foil 130 installed inside the thermal break strips 120, a protrusion 140 integrally formed with the profiles 110, and a slope 150 provided on one side wall of the profiles 110.

[0033] Furthermore, the profile 110 is integrally formed with multiple extensions 200, which are arranged in pairs to form two groups. The two extensions 200 in each group are arranged in a figure-eight shape, and a groove 300 is formed between the two extensions 200 in each group. The extensions 200 provide conditions for firmly limiting the heat insulation strip 120.

[0034] Furthermore, two protrusions 400 are embedded inside the heat insulation strip 120. The two protrusions 400 are respectively attached to the top and bottom of the metal foil 130. The protrusions 400 are interference fit inside the slot 300. The protrusions 400 can make the outer wall of the heat insulation strip 120 fit the inner wall of the slot 300, reducing the probability of the heat insulation strip 120 falling off.

[0035] Example 2:

[0036] Combination Figure 1 , 2 and Figure 5As shown, based on Embodiment 1, a heat insulation cavity is formed between the two slopes 150. The heat insulation cavity is designed to be narrow and deep, and its shape design can reduce the contact area between the outdoor surface and sunlight.

[0037] Furthermore, an aerogel felt 500 is embedded on one side of the profile 110. The aerogel felt 500 is located inside the heat insulation cavity. The aerogel felt 500 has excellent heat insulation performance and can effectively block heat conduction and heat radiation.

[0038] Example 3:

[0039] Combination Figure 1 and Figure 5 As shown, in the above embodiment, a paraffin-based composite material 600 is embedded on the other side of the profile 110. The vertical cross section of the paraffin-based composite material 600 is set to L-shape. When it is hot, the paraffin-based composite material 600 can absorb outdoor heat, assist the profile 110 in storing heat on the indoor side, balance the temperature difference between day and night, and improve the thermal inertia index.

[0040] The working principle and usage process of this utility model: When this product is put into actual use, the narrow and deep heat insulation cavity can reduce the contact area between sunlight and profile 110, thereby reducing the temperature rise of profile 110. Then, the two heat insulation strips 120 work together to reduce the transfer of high temperature. Here, the heat insulation strip 120 works with the metal foil 130 to form a sandwich structure of "heat insulation-reflection-heat insulation", which enhances the ability to reflect heat radiation. Through the multi-layer composite design, the thermal conductivity coefficient (U value) is reduced, effectively improving the heat insulation effect of this product. Furthermore, the multi-layer composite design also improves the strength of the bending heat insulation strip 120, solving the problem of easy deformation of the heat insulation strip 120.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
