Description

Technical Field

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

[0002] Composite aluminum profiles refer to a new type of profile formed by combining aluminum and aluminum alloys with other metal or non-metal materials through specific processes, resulting in comprehensive performance advantages. This type of profile retains the inherent lightweight, corrosion resistance, and ease of processing of aluminum, while also overcoming the shortcomings of single-material aluminum in terms of strength, heat insulation, sound insulation, and aesthetics through the combination with other materials. It is widely used in construction, transportation, electronics, and home furnishing, meeting diverse material performance requirements in different scenarios.

[0003] However, traditional composite aluminum profiles often use a single aluminum structure or are simply filled with ordinary insulation materials, allowing heat to be quickly conducted through the profile itself. Their insulation layer is often a continuous solid structure, lacking effective air barrier design, leading to intense heat exchange between indoors and outdoors in environments with significant temperature differences. For example, in the high temperatures of summer, outdoor heat easily penetrates the room, increasing air conditioning energy consumption; in winter, it is difficult to prevent indoor heat loss. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional composite aluminum profiles have poor thermal insulation performance and cannot meet the requirements of some scenarios with high thermal insulation requirements, and to propose a composite aluminum profile with a thermal insulation layer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a composite aluminum profile with a heat insulation layer, comprising two aluminum profile shells, the two aluminum profile shells being bonded to each other, each of the two aluminum profile shells having an installation groove on one side, the two installation grooves being aligned to form an installation area, a composite heat insulation layer being fixedly bonded inside the installation groove, the composite heat insulation layer comprising a frame and a heat insulation core, the heat insulation core being filled inside the frame.

[0006] Preferably, the connecting surfaces of the two aluminum profile shells have a serrated interlocking structure.

[0007] Preferably, a high-temperature resistant sealant layer is provided between the serrated interlocking structures.

[0008] Preferably, the skeleton is a regular hexagonal honeycomb grid structure.

[0009] Preferably, the thickness of the composite insulation layer is 1 to 3 mm.

[0010] Preferably, the heat insulation core includes a nano-aerogel layer and a polyurethane foam layer, wherein the polyurethane foam layer is disposed inside the nano-aerogel layer.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, heat is locked by the cooperation of the skeleton and the heat insulation core in the composite heat insulation layer. The heat insulation core is filled inside the skeleton, which not only makes full use of the space of the skeleton, but also avoids problems such as compression and collapse of the heat insulation core during long-term use with the support of the skeleton, ensuring the long-lasting heat insulation effect and preventing heat from being transferred to the external environment through another aluminum profile shell, thereby achieving the function of heat insulation and heat preservation.

[0012] 2. In this utility model, a synergistic effect of dual barrier and gradient heat insulation is achieved through a layered design. The nano-aerogel layer, as the outer layer, can directly block the rapid conduction of high or low temperatures from the outside environment due to its nanoscale porous structure and extremely low thermal conductivity, which is equivalent to setting up the first "barrier" in the heat transfer path; while the polyurethane foam layer located inside further weakens the convection transfer of heat through a large number of closed pores, forming a second "buffer zone", which can more stably maintain the temperature gradient on both sides of the profile and reduce energy loss.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a composite aluminum profile with a heat insulation layer, including two aluminum profile shells 1, which are bonded together. Each of the two aluminum profile shells 1 has a mounting groove 11 on one side, and the two mounting grooves 11 are aligned to form an installation area. A composite heat insulation layer 2 is fixedly bonded inside the mounting groove 11. The composite heat insulation layer 2 includes a skeleton 21 and a heat insulation core 22. The heat insulation core 22 is filled inside the skeleton 21. The connecting surface of the two aluminum profile shells 1 is a sawtooth interlocking structure, and a high-temperature resistant sealant layer is provided between the sawtooth interlocking structures. The skeleton 21 is a regular hexagonal honeycomb grid structure, and the thickness of the composite heat insulation layer 2 is 1-3 mm.

[0018] The specific settings and functions of this embodiment will be described in detail below. The two aluminum profile shells 1 are made of 6063-T5 aluminum alloy with a thickness of 1.5mm. This material has excellent oxidation resistance and processing performance, providing reliable structural support for the composite aluminum profile while also meeting the requirements for lightweighting, ensuring that the profile is not easily deformed during installation and use.

[0019] The mounting groove 11 is precisely designed with a depth of 2mm and a width that matches the width of the composite insulation layer 2, ensuring that the composite insulation layer 2 can be tightly embedded within it. The interior of the mounting groove 11 undergoes a special surface treatment, increasing the friction and bonding area with the composite insulation layer 2. Combined with a dedicated thermal insulation adhesive, this ensures a firm bond between the composite insulation layer 2 and the aluminum profile shell 1, preventing displacement of the composite insulation layer 2 due to vibration, temperature changes, or other factors during the use of the profile, thereby guaranteeing the stability of the overall thermal insulation performance.

[0020] The skeleton 21 is made of modified polyamide material, which has high strength, stiffness and heat resistance, and can withstand pressure from both the inside and outside sides to maintain the integrity of the regular hexagonal honeycomb grid structure. At the same time, the closed space formed between the honeycomb grids also provides a favorable structural basis for the heat insulation core 22 to perform its heat insulation function.

[0021] The heat insulation core 22 has excellent heat insulation performance. Filling the interior of the frame 21 with the heat insulation core 22 can not only make full use of the space of the frame 21, but also use the support of the frame 21 to avoid problems such as compression and collapse of the heat insulation core 22 during long-term use, thus ensuring the durability of the heat insulation effect.

[0022] The tooth height of the serrated interlocking structure is 1mm and the tooth pitch is 2mm. This structural design greatly increases the contact area of ​​the two aluminum profile shells 1 connecting surfaces, and improves the overall strength and sealing of the connection part.

[0023] In summary, through the specific design of each component, the composite aluminum profile with the thermal insulation layer possesses excellent thermal insulation performance while maintaining good structural strength and stability, enabling it to adapt to the usage requirements of different environments.

[0024] Example 2: Figure 1 - Figure 4 As shown, the composite aluminum profile with a heat insulation layer in this utility model includes two aluminum profile shells 1, which are bonded to each other. Each of the two aluminum profile shells 1 has a mounting groove 11 on one side, and the two mounting grooves 11 are aligned to form an installation area. A composite heat insulation layer 2 is fixedly bonded inside the mounting groove 11. The composite heat insulation layer 2 includes a skeleton 21 and a heat insulation core 22. The heat insulation core 22 is filled inside the skeleton 21. The heat insulation core 22 includes a nano aerogel layer 221 and a polyurethane foam layer 222. The polyurethane foam layer 222 is disposed inside the nano aerogel layer 221.

[0025] The overall effect of this embodiment is that a synergistic effect of dual barrier and gradient thermal insulation is achieved through a layered design. The nano-aerogel layer 221, as the outer layer, can directly block the rapid conduction of high or low temperatures from the outside environment due to its nanoscale porous structure and extremely low thermal conductivity, which is equivalent to setting up the first "barrier" in the heat transfer path; while the polyurethane foam layer 222 located inside further weakens the convection transfer of heat through a large number of closed pores, forming a second "buffer zone", which can more stably maintain the temperature gradient on both sides of the profile and reduce energy loss.

[0026] In terms of structural stability, the nano-aerogel layer 221 itself has a certain degree of rigidity and compressibility. Encasing the polyurethane foam layer 222 within it can effectively constrain the creep or shrinkage of the foam material during long-term use, preventing voids or gaps in the insulation core 22 due to foam deformation. Simultaneously, this "hard outside, flexible inside" structure better adapts to the honeycomb grid of the skeleton 21: the outer nano-aerogel layer 221 can fit tightly against the inner wall of the skeleton 21, ensuring the density of the filling; the inner polyurethane foam layer 222 can compensate for dimensional errors in the skeleton 21 grid through slight deformation, ensuring that the insulation core 22 within each grid unit can fully function, reducing insulation failure caused by assembly gaps.

[0027] The device's operation and working principle are as follows: The composite aluminum profile is installed at the appropriate location. Heat from the internal environment enters the aluminum profile shell 1 through heat transfer. With the cooperation of the skeleton 21 and the insulation core 22 in the composite insulation layer 2, heat is locked, preventing heat from being transferred to the external environment through the other aluminum profile shell 1, thus achieving heat insulation. The insulation core 22 achieves a synergistic effect of double barrier and gradient insulation through its layered design. The nano-aerogel layer 221, as the outer layer, with its nano-porous structure and extremely low thermal conductivity, can directly block the rapid conduction of high or low temperatures from the outside, essentially setting up the first "barrier" in the heat transfer path. Meanwhile, the inner polyurethane foam layer 222 further weakens the convective transfer of heat through numerous closed pores, forming a second "buffer zone," which can more stably maintain the temperature gradient on both sides of the profile and reduce energy loss.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
