Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and more specifically, to a door and window aluminum profile with multiple thermal insulation structures. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, energy conservation and emission reduction in the building sector have become crucial. Building energy consumption accounts for 30%-40% of total societal energy consumption, and windows and doors, as the weakest link in the building envelope, account for 25%-35% of total building energy loss. In winter, indoor heat is rapidly lost through windows and doors; in summer, a large amount of outdoor heat enters, causing air conditioning and heating equipment to operate at high loads for extended periods, resulting in significant energy waste. Therefore, improving the thermal insulation performance of windows and doors has become a core requirement for reducing building energy consumption and achieving green building goals.

[0003] There are many existing technologies for thermally insulated aluminum profiles, such as:

[0004] Chinese Patent (Application No.: CN202222816687.9) discloses a thermally insulated and sound-insulating thermally broken aluminum profile for doors and windows, including a first aluminum profile and a second aluminum profile. The second aluminum profile is disposed above the first aluminum profile, and slots are provided on the facing surfaces of the first and second aluminum profiles. In this utility model, two V-shaped sound insulation boards are inserted into the cavities of the first and second aluminum profiles, causing the two ends of the two sound insulation boards to extend into the positioning strips correspondingly disposed on the inner walls of the first and second aluminum profiles, thereby dividing the cavities of the first and second aluminum profiles into three compartments. By filling the compartment between the two sound insulation boards with inner sound insulation cotton and then filling the other two compartments with outer sound insulation cotton, the inner sound insulation cotton, outer sound insulation cotton, and sound insulation boards form a multi-layer sound insulation structure. Compared with the traditional single-layer sound insulation structure, it can fully absorb the sound transmitted to the first and second aluminum profiles, effectively improving the sound insulation effect.

[0005] In traditional thermal break aluminum profiles, the thermal break strip structure is relatively small compared to the aluminum profile. Therefore, when connecting two aluminum profiles with a simple thermal break strip, the connection strength is insufficient, and it is easy to deform under stress, resulting in the thermal break strip falling off or cracking at the connection, which affects the overall performance. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a multi-insulation aluminum profile for doors and windows. It solves the problem that the connection strength between the insulation components and the aluminum profile in traditional aluminum profiles is insufficient, and the profile is prone to deformation under stress, which can lead to the insulation strip falling off or cracking at the connection, thus affecting the overall performance.

[0007] To achieve the above objectives, this utility model provides a multi-insulation aluminum profile for doors and windows, including a first profile, a second profile disposed on one side of the first profile, and an insulation component disposed between the first profile and the second profile. The insulation component includes an insulation element, and two insulation strips are symmetrically disposed within the internal cavity of the insulation element. The upper and lower surfaces of the insulation strips are provided with wavy edges to extend the heat conduction path. Through the combined use of the insulation element and the insulation strips, effective insulation of the first and second profiles is ensured while improving the connection strength between the first and second profiles.

[0008] The beneficial effects of this utility model are:

[0009] 1. In terms of thermal insulation performance, the thermal insulation effect of aluminum profiles is improved by the composite thermal insulation system of thermal insulation components, thermal insulation strips and first and second profiles, and the wavy edge on the surface of the thermal insulation strip extends the heat conduction trajectory and increases thermal resistance.

[0010] 2. In terms of connection strength, the thermal insulation component can achieve quick connection with the first and second profiles while providing high-strength mechanical locking to prevent loosening and improve the overall structural strength.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Preferably, both the first profile and the second profile are fixedly connected to a snap-fit ​​block on the side near the heat insulation component, and the heat insulation component and the snap-fit ​​block are snap-fit ​​connected. The heat insulation strip is symmetrically fixedly connected to dovetail blocks at both ends, and the heat insulation component cavity is symmetrically provided with dovetail grooves on both sides, and the dovetail blocks are snap-fit ​​connected inside the dovetail grooves.

[0013] The beneficial effects of adopting the above-mentioned further solutions are that it can quickly complete the connection between the thermal insulation component and the profile, improve the connection strength, achieve a high-strength mechanical connection between the profile and the thermal insulation component, avoid loosening, and the tight interlocking structure of the thermal insulation strip and the thermal insulation component reduces the possibility of external moisture and dust entering the interior of the thermal insulation component, and reduces the performance degradation of the thermal insulation strip due to corrosion or oxidation.

[0014] Preferably, a reinforcing plate is fixedly connected inside the heat insulation component.

[0015] The beneficial effect of adopting the above-mentioned further solutions is to enhance the deformation resistance of the thermal insulation components and improve the overall structural strength of the thermal insulation components.

[0016] Preferably, the outer surfaces of both the heat insulation component and the heat insulation strip are wrapped with a novel aerogel heat insulation felt.

[0017] The beneficial effects of adopting the above-mentioned further solutions are that aerogel has a nanoporous structure and a low thermal conductivity, further improving the thermal insulation effect. At the same time, aerogel insulation felt has good flexibility and weather resistance, and can be tightly adhered to the surface of aluminum profiles.

[0018] Preferably, both the first profile and the second profile are provided with a first chamber and a second chamber, the first chamber having an arc-shaped structure and the second chamber having a polygonal structure.

[0019] The beneficial effects of adopting the above-mentioned further solutions are that the still air in the multi-chamber can effectively hinder heat transfer, and the use of trapezoidal and arc-shaped chamber structures can increase the number of heat reflections in the chamber and reduce heat conduction compared with traditional rectangular chambers. At the same time, the multi-chamber forms a "mechanical skeleton" to improve the wind pressure resistance of the profile.

[0020] Preferably, guide posts are fixedly connected to the bottom of both the first profile and the second profile, and sealing strips are symmetrically engaged on both sides of the lower inner end of the first profile and the second profile.

[0021] The beneficial effects of adopting the above-mentioned further solutions are that the guide column assists in precise positioning during installation, reduces installation errors, and the sealing strip forms a sealing structure, thereby improving the airtightness and watertightness of doors and windows.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] The interlocking connection between the insulation component and the snap-fit ​​block in the insulation component allows for quick connection between the insulation component and the profile while improving the connection strength. This achieves a high-strength mechanical connection between the profile and the insulation component, preventing loosening. Meanwhile, a reinforcing plate is installed inside the insulation component to enhance its resistance to deformation and improve the overall structural strength. Furthermore, the composite structure of the insulation strip and the insulation component forms a "double thermal break" insulation system. The wavy edge on the surface of the insulation strip extends the heat conduction path, increases thermal resistance, and slows down the heat transfer rate. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-3 As shown, this embodiment provides a multi-insulation aluminum profile for doors and windows, including a first profile 1, with a second profile 2 disposed on one side of the first profile 1. Considering that the connection strength between the thermal insulation component 3 and the aluminum profile in traditional aluminum profiles is insufficient and they are prone to deformation under stress, resulting in the thermal insulation strip 34 falling off or cracking at the connection, affecting the overall performance, a thermal insulation component 3 is disposed between the first profile 1 and the second profile 2. The thermal insulation component 3 includes a thermal insulation element 31, and two thermal insulation strips 34 are symmetrically disposed in the internal cavity of the thermal insulation element 31. The upper and lower surfaces of the thermal insulation strips 34 are provided with wavy edges 37 to extend the heat conduction path. Through the combined use of the thermal insulation element 31 and the thermal insulation strips 34, the first profile 1 and the second profile 2 are effectively insulated while the connection strength between the first profile 1 and the second profile 2 is improved.

[0034] In summary, the improvement of this embodiment lies in:

[0035] The insulation component 31 in the insulation component 3 is connected between the first profile 1 and the second profile 2 to improve the connection strength between the two profiles and prevent loosening. The composite structure of the insulation strip 34 and the insulation component 31 forms a "double thermal break" insulation system. The wavy edge 37 set on the surface of the insulation strip 34 extends the heat conduction path, increases thermal resistance, and slows down the heat transfer speed.

[0036] Based on the above, other structures also need to be disclosed in detail, such as:

[0037] In order to improve the ease of connection and stability of the connection between the heat insulation component 3 and the first profile 1 and the second profile 2, a snap-fit ​​block 32 is fixedly connected to the side of the first profile 1 and the second profile 2 near the heat insulation component 31. The heat insulation component 31 and the snap-fit ​​block 32 are snap-fit ​​connected, which can quickly complete the connection between the heat insulation component 3 and the profile, improve the connection strength, realize a high-strength mechanical connection between the profile and the heat insulation component 3, and avoid loosening.

[0038] The heat insulation component 31 is internally fixedly connected with a reinforcing plate 33, which enhances the deformation resistance of the heat insulation component 3 and improves the overall structural strength of the heat insulation component 3.

[0039] To improve the connection strength between the thermal insulation strip 34 and the thermal insulation component 31, dovetail blocks 35 are symmetrically fixedly connected to both ends of the thermal insulation strip 34, and dovetail grooves 36 are symmetrically arranged on both sides of the cavity of the thermal insulation component 31. The dovetail blocks 35 are engaged and connected inside the dovetail grooves 36, forming a two-way locking effect after engagement: when engaged laterally, the beveled surfaces generate mutual squeezing friction, preventing the thermal insulation strip 34 from being pulled out axially; when subjected to longitudinal force, the beveled surfaces convert the external force into vertical pressure, enhancing the shear resistance. The tight engagement structure reduces the possibility of external moisture and dust entering the interior of the thermal insulation component 3, reducing the performance degradation of the thermal insulation strip 34 due to corrosion or oxidation.

[0040] To improve the thermal insulation effect of the thermal insulation component 3, the outer surfaces of both the thermal insulation element 31 and the thermal insulation strip 34 are wrapped with a novel aerogel thermal insulation felt. The aerogel has a nanoporous structure and a low thermal conductivity, further enhancing the thermal insulation effect. At the same time, the aerogel thermal insulation felt has good flexibility and weather resistance, and can be tightly adhered to the surface of the aluminum profile.

[0041] Considering that air is a poor conductor of heat, in order to improve the heat insulation effect of the profiles, both the first profile 1 and the second profile 2 are provided with a first chamber 4 and a second chamber 5. The first chamber 4 has an arc-shaped structure, and the second chamber 5 has a polygonal structure. The chambers are isolated from each other to form an air insulation layer. The still air in the multi-chamber can effectively hinder heat transfer. Moreover, the use of trapezoidal and arc-shaped chamber structures can increase the number of heat reflections in the chamber and reduce heat conduction compared to traditional rectangular chambers. At the same time, the multi-chamber forms a "mechanical skeleton" to improve the wind pressure resistance of the profiles.

[0042] Considering that gaps are prone to appear during the installation of traditional doors and windows, leading to air infiltration, reduced heat insulation performance, and potential water leakage, guide posts 6 are fixedly connected to the bottom of both the first profile 1 and the second profile 2. Sealing strips 7 are symmetrically engaged on both sides of the lower end of the first profile 1 and the second profile 2. The guide posts 6 assist in precise positioning during installation and reduce installation errors, while the sealing strips 7 form a sealing structure, improving the airtightness and watertightness of the doors and windows.

[0043] In summary, the working principle of this solution is as follows:

[0044] In terms of thermal insulation performance, a composite thermal insulation system is constructed through a "double-break bridge" and a multi-chamber structure. The thermal insulation component 31 and the double-layer thermal insulation strip 34 in the thermal insulation assembly 3 form a "double-break bridge," blocking the heat conduction path between the first profile 1 and the second profile 2. The wavy edge 37 on the surface of the thermal insulation strip 34 extends the heat conduction trajectory, increasing thermal resistance. Simultaneously, the arc-shaped and polygonal multi-chamber structure of the first chamber 4 and the second chamber 5 inside the first profile 1 and the second profile 2 utilizes the low thermal conductivity of air to form an insulation layer. Furthermore, the arc-shaped and polygonal chambers increase the number of heat reflections, further reducing heat conduction efficiency. In addition, the aerogel thermal insulation felt wrapped around the thermal insulation component 31 and the thermal insulation strip 34, with its nanoporous structure and ultra-low thermal conductivity, inhibits heat transfer from three dimensions: radiation, conduction, and convection.

[0045] In terms of connection strength, the multi-layered structural design ensures a stable connection between the profiles. The thermal insulation component 31 is connected to the first profile 1 and the second profile 2 by snap-fit ​​blocks 32, providing high-strength mechanical locking while enabling quick installation; the dovetail blocks 35 at both ends of the thermal insulation strip 34 engage with the dovetail grooves 36 of the cavity of the thermal insulation component 31 to form a two-way locking, improving pull-out and shear resistance; the reinforcing plate 33 inside the thermal insulation component 31 enhances the component's resistance to deformation, jointly ensuring the overall structural strength.

[0046] In terms of sealing performance, the guide column 6 and the sealing strip 7 work together to optimize installation and sealing effect. The guide column 6 assists in the precise positioning of the profile and reduces installation errors; the sealing strip 7 forms a sealing structure at the lower end of the profile, effectively blocking air infiltration and rainwater intrusion, further improving the airtightness and watertightness of doors and windows, thereby reducing energy consumption and improving building comfort.
