Description

Technical Field

[0001] This utility model relates to the field of profile technology, and in particular to a thermal insulation aluminum profile. Background Technology

[0002] In furniture decoration, windows are one of the main channels for heat exchange between the inside and outside of a building. High-quality insulated windows can effectively reduce heat loss, maintain a stable indoor temperature, and avoid excessively cold indoor temperatures in winter or excessively hot indoor temperatures in summer.

[0003] In related technologies, insulation boards, such as graphite polystyrene boards, are pasted on the inside and outside of windows. Before pasting, it is necessary to ensure that the insulation boards are cut properly and to use special adhesive mortar for pasting. After pasting, holes are drilled in the insulation boards to install insulation nails, and alkali-resistant fiberglass mesh is hung. Finally, a plastering mortar is applied.

[0004] However, the above methods have drawbacks in terms of poor insulation performance. The insulation effect of pasted insulation boards is affected by various factors such as outdoor temperature, wind speed, and humidity. Under extreme weather conditions, the insulation effect may be significantly reduced, increasing the risk of accidents. Furthermore, the connection between the window and the wall is a major area where thermal bridging occurs. Pasted insulation boards may not completely isolate the thermal bridging effect, allowing heat to be transferred through the thermal bridges and affecting the insulation performance. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides a thermal insulation aluminum profile, which uses thermal insulation strips to connect the inner frame and the outer frame to form two thermal insulation cavities to enhance the thermal insulation effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figures 1 to 5 The thermal insulation aluminum profile shown includes: inner frame 1, outer frame 2, and thermal insulation strip 3;

[0031] like Figure 1As shown, the inner frame 1 includes a first side 11 and a second side 12 that are perpendicular to each other, and grooves are provided on the outer sides of the first side 11 and the second side 12. It should be noted that the shape of the grooves can be trapezoidal, U-shaped, C-shaped, or even dovetail-shaped.

[0032] The outer frame 2 includes a first outer edge 21 and a second outer edge 22 that are perpendicular to each other. Both the first outer edge 21 and the second outer edge 22 include the same groove as the first edge 11 and the second edge 12. By configuring the grooves on the first outer edge 21 and the second outer edge 22 to have the same shape, the processing cost can be reduced.

[0033] The inner frame 1 and outer frame 2 are made of aluminum. The insulated aluminum profile also includes two thermal break strips 3. Each thermal break strip 3 has two ends along its length that correspond to the groove shapes on the first side 11, second side 12, first outer side 21, and second outer side 22. The thermal break strips 3 connect the parallel first side 11 and first outer side 21, and also connect the parallel second side 12 and second outer side 22. Aluminum itself has certain thermal insulation properties, effectively preventing heat transfer. Aluminum is hard, has high strength and toughness, can withstand large loads, and has good corrosion resistance, resisting the erosion of various chemicals. The aluminum insulated profile has excellent thermal insulation performance and structural stability, while also extending its service life. It should be noted that the material of the thermal insulation strip 3 can be PA66GF25, PVC, or PU. The thermal insulation strip 3 connects the inner frame 1 and the outer frame 2. Further reinforcement is achieved by applying an adhesive layer to the side of the thermal insulation strip 3 that contacts the inner frame 1 or outer frame 2, or by using clips or screws to further secure the thermal insulation strip 3 to the inner frame 1 or outer frame 2, thereby increasing the bonding strength between the thermal insulation strip 3 and the inner frame 1. With the thermal insulation strip 3, the insulated aluminum profile has two thermal insulation chambers, which can block some heat transfer, significantly reducing heat conduction through the profile itself. In winter, this effectively prevents indoor heat loss to the outside, and in summer, it effectively prevents outdoor high temperatures from entering the room, improving insulation performance and contributing to energy conservation and emission reduction. Furthermore, the two thermal insulation chambers enhance the structural stability of the profile. The thermal insulation strip 3, as part of the insulated aluminum profile, such as... Figure 2 As shown, it disperses and bears forces in all directions, thereby improving the profile's resistance to deformation and extending the service life of the insulated aluminum profile; it should also be noted that insulated aluminum profiles are not only used for building doors and windows, but also for curtain wall systems.

[0034] In some embodiments of this utility model, such as Figure 3-4As shown, the surfaces of the grooves on the first side 11, second side 12, first outer side 21, and second outer side 22 that contact the heat insulation strip 3 have protrusions 5. Providing protrusions 5 at appropriate positions in the grooves increases the contact area and friction between the heat insulation strip 3 and the inner frame 1 and outer frame 2, thereby preventing the heat insulation strip 3 from loosening or falling off due to external forces during long-term use. It should be noted that the protrusions 5 can be located on the edge of the groove or on the contact surface between the heat insulation strip 3 and the groove; it should also be noted that the shape of the protrusions 5 is not limited to the following. Figure 3-4 The triangular shape with rounded corners shown can also be a wavy line, a rounded serrated shape, or other irregular shapes.

[0035] In some embodiments of this utility model, the thermal insulation strip 3 is made of PVC or PA66GF25. PVC is lightweight, has good thermal insulation properties, and is easy to process, making it suitable for applications where thermal insulation performance requirements are not high. PA66GF25, on the other hand, has high performance. The thermal insulation strip 3 made of PA66GF25 has excellent thermal stability and durability, and can withstand large temperature changes without easily aging or cracking. At the same time, its high strength and rigidity also help improve the wind pressure resistance and structural stability of doors and windows, making it suitable for applications with higher requirements for thermal insulation performance, airtightness, and wind pressure resistance. Furthermore, the linear expansion coefficient of PA66GF25 is close to that of aluminum profiles. This characteristic allows the thermal insulation strip 3 to maintain a tight bond with the aluminum profile under high temperature differences, without displacement or detachment. Those skilled in the art can select the material of the thermal insulation strip 3 according to their needs.

[0036] In some embodiments of this utility model, such as Figure 5 As shown, the space enclosed by the outer frame 2, the inner frame 1, and the thermal insulation strip 3 is filled with PU foam 4. Filling the thermal insulation cavity with PU foam 4 can further improve its thermal insulation performance. PU foam 4 is a material with excellent thermal insulation properties and can effectively isolate heat transfer.

[0037] In some embodiments of this utility model, the surfaces of the inner frame 1 and the outer frame 2 have undergone anodizing treatment. Anodizing is an electrolytic oxidation process in which aluminum material acts as the anode, and through the action of current in an electrolytic cell containing electrolyte, its surface undergoes an oxidation reaction, generating a dense and hard aluminum oxide film. This oxide film has good corrosion resistance, hardness, and wear resistance, which can significantly improve the protective ability and service life of the aluminum material, thus making the thermal insulation profile have a longer service life.

[0038] In some embodiments of this utility model, the inner frame 1 and the outer frame 2 are covered with a protective film. It should be noted that the protective film can be made of PE or PVC. By covering the surface of the insulated aluminum profile, the protective film can prevent the adhesion of dust, stains, and other contaminants, maintaining the cleanliness of the profile, enhancing its wear resistance and corrosion resistance, and extending its service life.

[0039] In some embodiments of this utility model, such as Figure 3-4 As shown, the grooves in the first side 11, second side 12, first outer side 21, and second outer side 22 are trapezoidal, and the two ends of the heat insulation strip 3 corresponding to the grooves are also trapezoidal. The trapezoidal grooves and the trapezoidal shapes at both ends of the heat insulation strip 3 ensure a tight fit between the first side 11, second side 12, first outer side 21, and second outer side 22 and the heat insulation strip 3, preventing loosening or detachment. The joints can be reinforced with an adhesive layer, making the connection between the heat insulation strip 3 and the outer frame 2 and inner frame 1 more secure and less prone to loosening. The structurally stable thermal insulation aluminum profile further effectively blocks the heat transfer path and improves the thermal insulation performance.

[0040] In some embodiments of this utility model, such as Figure 1-2 As shown in Figures 1 and 5, the inner frame 1 also includes a third side 13 perpendicular to the first side 11 and a fourth side 14 perpendicular to the second side 12. The inner sides of both the first side 11 and the second side 12 are provided with first reinforcing ribs 15, which are L-shaped. The inner sides of both the third side 13 and the fourth side 14 have second reinforcing ribs 16 opposite to the first reinforcing ribs 15. By placing the first reinforcing ribs 15 inside the first side 11 and the second side 12, the cross-sectional area of ​​the profile is increased and its cross-sectional shape is changed. The L-shaped first reinforcing ribs 15 can significantly improve the load-bearing capacity of the profile, making it more robust and durable. The second reinforcing ribs 16 are placed inside the third side 13 and the fourth side 14, and their cross-sectional shape can be straight, arc-shaped, or other shapes, increasing the cross-sectional area of ​​the profile and changing its cross-sectional shape, further enhancing the structural strength and stability of the profile.

[0041] In some embodiments of this utility model, the outer sides of the first side 11 and the second side 12 are provided with semi-cylindrical third reinforcing ribs 17. The semi-cylindrical third reinforcing ribs 17 provide support while also offering cushioning and shock absorption. By increasing the cross-sectional area of ​​the profile and changing its cross-sectional shape, the semi-cylindrical third reinforcing ribs 17 significantly improve the profile's bending, torsional, and shear resistance, making the profile more stable and reliable under various complex loads. The third reinforcing ribs 17, together with the first reinforcing ribs 15 and the second reinforcing ribs 16, jointly improve the load-bearing capacity and stability of the frame.

[0042] In some embodiments of this utility model, such as Figure 1The inner frame 1 has a 90-degree inward bend at one corner away from the connection with the outer frame 2. The 90-degree inward bend is formed by processes such as stamping and bending, which helps to improve the structural stability of the profile. This 90-degree inward bend is used for connection with the wall, etc. The bend shape makes the connection more stable, improves the structural stability, and further improves the thermal insulation performance of the profile.

[0043] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
