Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and in particular to a multi-cavity heat-insulating aluminum profile. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the mechanical properties and application areas of the produced industrial aluminum profiles vary depending on the proportion of alloys added. Generally speaking, industrial aluminum profiles refer to all aluminum profiles except those used for building doors and windows, curtain walls, interior and exterior decoration, and building structures. The core production process of aluminum profiles includes: casting: raw material batching → melting and impurity removal → casting into round cast rods; extrusion: heating the cast rods and extruding them through molds, supplemented by air-cooling quenching and artificial aging strengthening; surface treatment: including anodizing, electrophoretic coating, powder coating, etc., to improve weather resistance and aesthetics. Traditional aluminum profiles are a weak link in building energy consumption due to the high thermal conductivity of metal. To solve this problem, insulated aluminum profiles use a "broken bridge" design to block the heat conduction path. By embedding low thermal conductivity materials (such as nylon 66 thermal insulation strips or injection-molded polyurethane) between the inner and outer aluminum profiles, a thermal barrier layer is formed to reduce the heat transfer coefficient of doors and windows and meet building energy conservation standards.

[0003] However, there is still room for improvement in the thermal insulation capacity of existing thermally insulated aluminum profiles in order to adapt to application environments with higher thermal insulation performance requirements. Utility Model Content

[0004] Therefore, it is necessary to provide a multi-cavity thermal insulation aluminum profile to address the technical problem of insufficient thermal insulation capacity of existing thermal insulation aluminum profiles.

The third thermal insulation cavity is disposed on the side closer to the connecting surface, the first thermal insulation cavity is disposed opposite the third thermal insulation cavity at the other end of the main body, and the second thermal insulation cavity is disposed between the first thermal insulation cavity and the third thermal insulation cavity, thereby forming a multi-cavity thermal insulation structure.

[0006] The second heat insulation cavity is provided with a first heat insulation layer, a second heat insulation layer and a reinforcing structure. The first heat insulation layer and the second heat insulation layer are arranged sequentially from one side of the first functional surface to the opposite side, and the reinforcing structure is provided on one side of the second functional surface.

[0007] In one embodiment, the first heat insulation layer is configured as an aerogel felt layer, the second heat insulation layer is configured as a vacuum microsphere layer, and the reinforcing structure is configured as a T-shaped reinforcing rib.

[0008] In one embodiment, the first heat insulation cavity includes an outer heat insulation cavity, an inner heat insulation cavity, and a connecting structure; the outer heat insulation cavity and the inner heat insulation cavity are disposed opposite to each other at both ends of the first heat insulation cavity; wherein, the outer heat insulation cavity is disposed near the first functional surface; the inner heat insulation cavity is disposed near the second functional surface; the outer heat insulation cavity and the inner heat insulation cavity are connected by the connecting structure.

[0011] In one embodiment, the two connecting structures described above are arranged parallel to each other on both sides of the first heat insulation cavity.

[0012] In one embodiment, the substrate is made of glass fiber nylon 66 to form a broken bridge structure.

[0013] In one embodiment, the bottom wall of the outer heat insulation cavity and the top wall of the inner heat insulation cavity are provided with a fastening part for each fastener, and the fastening part can cooperate with the corresponding fastener to fasten.

[0014] In one embodiment, the connecting surface is provided with two connecting grooves, which are located on both sides of the connecting surface along the length of the main body, thereby forming a connecting structure.

[0015] In one embodiment, the aforementioned connecting groove is configured as a T-groove.

[0016] In one embodiment, both the first functional surface and the second functional surface are provided with a first mating groove and a second mating groove, and the first mating groove and the second mating groove extend along the length direction of the main body.

[0017] In one embodiment, the first functional surface is further provided with a plurality of drainage channels, which are arranged parallel to each other along the length of the main body on the first functional surface.

[0032] Please see Figures 1 to 2This utility model discloses a multi-cavity heat-insulating aluminum profile 1, which includes a main body. The main body is configured as an aluminum alloy profile structure with multiple cavities that extend uniformly in one direction. Specifically, the main body includes a first functional surface 10, a second functional surface 20, and a connecting surface 30. The first functional surface 10 and the second functional surface 20 are respectively disposed on opposite sides of the main body, and the connecting surface 30 is disposed between the first functional surface 10 and the second functional surface 20, on one end face of the main body. The main body is provided with a first heat-insulating cavity a, a second heat-insulating cavity b, and a third heat-insulating cavity c. The first heat-insulating cavity a, the second heat-insulating cavity b, and the third heat-insulating cavity c are disposed between the first functional surface 10 and the second functional surface 20. The third heat-insulating cavity c is disposed on the side closer to the connecting surface 30. The first heat-insulating cavity a is disposed at the other end of the main body opposite to the third heat-insulating cavity c, and the second heat-insulating cavity b is disposed between the first heat-insulating cavity a and the third heat-insulating cavity c, thereby forming a multi-cavity heat-insulating structure. The second insulation cavity b is provided with a first insulation layer b1, a second insulation layer b2, and a reinforcing structure b3. The first insulation layer b1 and the second insulation layer b2 are arranged sequentially from one side of the first functional surface 10 to the opposite side, and the reinforcing structure b3 is provided on one side of the second functional surface 20. More specifically, the first insulation layer b1 is an aerogel felt layer, the second insulation layer b2 is a vacuum microsphere layer, and the reinforcing structure b3 is a T-shaped reinforcing rib. Thus, the first insulation layer b1, together with the second insulation layer b2, can specifically enhance the insulation performance of the first functional surface 10. In practical applications, when the multi-cavity heat-insulating aluminum profile 1 is used for indoor and outdoor separation, the first functional surface 10 can be set facing the outside. Thus, the first insulation layer b1 combined with the second insulation layer b2 can improve the insulation capacity of the first functional surface 10, thereby ensuring the stability of the indoor temperature. Therefore, it can be seen that the multi-cavity thermal insulation aluminum profile 1 of this utility model can effectively enhance the solar radiation heat reflection capability and the heat conduction blocking capability of the aluminum profile by setting an aerogel felt layer and a vacuum microsphere plate layer on the first functional surface 10, i.e. the outdoor side. At the same time, the layered design of the double thermal insulation structure can effectively reduce the comprehensive thermal conductivity of the first functional surface 10, which can greatly enhance the thermal insulation performance compared with the traditional single-layer thermal insulation cavity. In addition, the third thermal insulation cavity c is set adjacent to the connecting surface 30. When the aluminum profile is connected to the building structure through the connecting surface 30, the third thermal insulation cavity c can form an end thermal buffer layer, thereby reducing the cold and heat bridge effect of the profile installation node.

[0033] Furthermore, the first heat insulation cavity a includes an outer heat insulation cavity a1, an inner heat insulation cavity a2, and a connecting structure a3. The outer heat insulation cavity a1 and the inner heat insulation cavity a2 are disposed opposite to each other at both ends of the first heat insulation cavity a; wherein, the outer heat insulation cavity a1 is disposed near the end of the first functional surface 10; the inner heat insulation cavity a2 is disposed near the second functional surface 20; the outer heat insulation cavity a1 and the inner heat insulation cavity a2 are connected by the connecting structure a3. Based on the above configuration, in one embodiment, the connecting structure a3 includes a base plate a31 and fasteners a32 at both ends, the two fasteners a32 being respectively connected to the opposite two sides of the base plate a31; the base plate a31 is disposed between the outer heat insulation cavity a1 and the inner heat insulation cavity a2, and the two sides of the base plate a31 are respectively connected to the outer heat insulation cavity a1 and the inner heat insulation cavity a2 by the two fasteners a32.

[0034] Furthermore, in one embodiment, the first heat insulation cavity a includes two connecting structures a3, with the outer heat insulation cavity a1 and the inner heat insulation cavity a2 connected by the two connecting structures a3. Specifically, the two connecting structures a3 are arranged parallel to each other on both sides of the first heat insulation cavity a. Based on the above arrangement, in one embodiment, the substrate a31 is made of glass fiber nylon 66 to form a broken bridge structure, thereby enhancing the heat insulation performance of the first heat insulation cavity a.

[0035] In one embodiment, the bottom wall of the outer heat insulation cavity a1 and the top wall of the inner heat insulation cavity a2 are provided with a fastening part a21 corresponding to each fastener a32. The fastening part a21 can cooperate with the corresponding fastener a32 to fasten, thereby enhancing the installation stability of each substrate a31.

[0036] Furthermore, the connecting surface 30 is provided with two connecting grooves d, which are arranged on both sides of the connecting surface 30 along the length of the main body, thereby forming a connecting structure a3 for connecting the aluminum profile to the surface of the building structure. In one embodiment, the connecting grooves d are specifically set as T-grooves to ensure connection stability.

[0037] Furthermore, both the first functional surface 10 and the second functional surface 20 are provided with a first mating groove e and a second mating groove f, and the first mating groove e and the second mating groove f extend along the length of the main body to be used for limiting and mating with the external building structure.

[0038] Furthermore, the first functional surface 10 is also provided with a number of drainage channels g. The drainage channels g are arranged parallel to each other along the length of the main body on the first functional surface 10. When the first functional surface 10 is located on the outdoor side, the drainage channels g can guide rainwater, thereby enhancing the rainproof function of the aluminum profile.

[0039] Furthermore, the average thickness of the first functional surface 10 is set to be 1.3-1.5 times the average thickness of the second functional surface 20; based on this, the bottom wall of each drainage trough g is set as an inclined surface with a slope of 5°, thereby forming an inclined drainage trough g. In practical applications, by coordinating with the reasonable setting of the gravity direction, the inclined drainage trough g can enhance the drainage capacity of the first functional surface 10.

[0040] Furthermore, in one embodiment, the reinforcing structure b3 is made of glass fiber nylon 66 to further ensure the thermal insulation function of the second thermal insulation cavity b.

[0041] In summary, when the multi-cavity thermally insulated aluminum profile disclosed in this utility model is used for indoor-outdoor separation, the first functional surface can face outwards. Thus, the first insulation layer combined with the second insulation layer can enhance the thermal insulation capacity of the first functional surface, thereby ensuring the stability of the indoor temperature. It can be seen that the multi-cavity thermally insulated aluminum profile of this utility model, by setting an aerogel felt layer and a vacuum microsphere layer on the first functional surface (i.e., the outdoor side), can effectively enhance the solar radiation heat reflection capacity and the heat conduction blocking capacity of the aluminum profile. Simultaneously, the layered design of the double-insulation structure can effectively reduce the overall thermal conductivity of the first functional surface, significantly enhancing the thermal insulation performance compared to traditional single-layer insulation cavities. Furthermore, the third insulation cavity is located adjacent to the connecting surface. When the aluminum profile is connected to the building structure through the connecting surface, the third insulation cavity can form an end thermal buffer layer, thereby reducing the thermal bridging effect at the profile installation joints.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
