Description

Technical Field

[0001] This utility model relates to the field of thermal insulation strip technology, specifically a multi-cavity encapsulated thermal insulation strip. Background Technology

[0002] Thermal insulation strips are key components used in building doors and windows, serving to insulate against heat, sound, and energy. They effectively prevent heat transfer through the door and window frames, reducing heat exchange between indoors and outdoors, and lowering energy consumption for air conditioning, heating, and other equipment, thus achieving energy savings. In summer, they prevent outdoor heat from entering the room, keeping it cool; in winter, they prevent indoor heat from escaping to the outside, keeping the room warm.

[0003] Chinese utility model patent CN213330615U discloses a multi-cavity heat insulation strip, including an outer heat insulation strip, an inner heat insulation strip at the side end of the outer heat insulation strip, a guide rod slidably connected inside the positioning sleeve, a retaining strip with a snap-fit ​​groove inside, an adjusting rod snapped into the snap-fit ​​groove, and a limiting spring welded to the inner wall of the supporting pressure plate. This utility model uses a heat insulation sleeve to cover the surfaces of the outer and inner heat insulation strips, connecting them together and reinforcing them with a reinforcing strip to form a multi-cavity heat insulation structure, ensuring heat insulation effect. Pulling the adjusting rod outward causes it to press against the surface of the limiting spring, simultaneously disengaging from the snap-fit ​​groove and entering the adjusting groove. This adjusts the distance between the two sets of reinforcing strips and changes the distance between the outer and inner heat insulation strips. After adjustment, releasing the adjusting rod causes the limiting spring to reset, causing the adjusting rod to press back against the inner wall of the snap-fit ​​groove, achieving overall fixation. The structure is simple and suitable for widespread application.

[0004] However, during the use of this utility model, the device contains a large number of mechanical structures, while the thickness and volume of a normal heat insulation strip are usually limited. Increasing these mechanical structures will greatly increase the difficulty of manufacturing the heat insulation strip and increase its weight, thereby affecting the installation efficiency of the heat insulation strip and failing to meet production needs. Therefore, a multi-cavity encapsulated heat insulation strip is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-cavity encapsulated thermal insulation strip, which has the advantage of high lightweight. It solves the problem that existing thermal insulation strips contain a large number of mechanical structures, while the thickness and volume of normal thermal insulation strips are usually limited. Adding these mechanical structures will significantly increase the manufacturing difficulty of the thermal insulation strip and increase its weight, thereby affecting the installation efficiency of the thermal insulation strip.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-cavity encapsulated heat insulation strip, comprising a first heat insulation strip and a second heat insulation strip at the bottom of the first heat insulation strip, wherein the interior of the first heat insulation strip is provided with a multi-cavity heat insulation structure;

[0007] The multi-cavity thermal insulation structure includes a first fin fixedly connected to the top of the first thermal insulation strip. The first thermal insulation strip has five cavities inside. A filler is provided between the first thermal insulation strip and the second thermal insulation strip.

[0008] Furthermore, the first heat insulation strip and the second heat insulation strip have the same shape and structure, and the first heat insulation strip and the second heat insulation strip are symmetrically distributed.

[0009] Furthermore, the number of the first fins is four, and the first fins are made of the same material as the first heat insulation strip.

[0010] Furthermore, each cavity is fixedly connected to a partition, and the left and right sides of the first heat insulation strip are fixedly connected to a second fin.

[0011] Furthermore, both the first and second heat insulation strips have a covering layer on their outer surfaces, and the thickness of the covering layer is 1 mm.

[0012] Compared with the prior art, this utility model provides a multi-cavity wrapped thermal insulation strip, which has the following beneficial effects:

[0013] This multi-cavity encapsulated thermal insulation strip, with its five independent cavities, reduces heat conduction paths, lowers heat transfer efficiency, and enhances insulation performance. The filler between the first and second thermal insulation strips reduces air convection, prevents heat loss, and enhances thermal insulation performance. It also reduces localized stress, increasing overall stability. The filler further optimizes sound wave reflection and absorption, improving noise reduction. The hollow design reduces material usage and weight while maintaining high structural strength and compressive strength. This design solves the problem of existing thermal insulation strips containing numerous mechanical structures, which significantly increase manufacturing difficulty and weight, impacting installation efficiency due to the limited thickness and volume of typical thermal insulation strips.

[0017] 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.

[0018] Please see Figures 1 to 2 In this embodiment, a multi-cavity encapsulated heat insulation strip includes a first heat insulation strip 1 and a second heat insulation strip 2 at the bottom of the first heat insulation strip 1. The first heat insulation strip 1 has a multi-cavity heat insulation structure inside. The multi-cavity heat insulation structure includes a first fin 5 fixedly connected to the top of the first heat insulation strip 1. The first heat insulation strip 1 has five cavities 3 inside. A filler 4 is provided between the first heat insulation strip 1 and the second heat insulation strip 2.

[0019] Specifically, the first heat insulation strip 1 and the second heat insulation strip 2 have the same shape and structure, and are symmetrically distributed. There are four first fins 5, and the first fins 5 are made of the same material as the first heat insulation strip 1. By setting five independent cavities 3, the heat conduction path can be reduced, the heat transfer efficiency can be reduced, and the heat insulation effect can be enhanced. At the same time, the hollow design can reduce the amount of material used and the weight, while maintaining high structural strength and compressive strength.

[0020] It should be noted that each cavity 3 is fixedly connected with a partition, and the left and right sides of the first heat insulation strip 1 are fixedly connected with the second fin 6. The filling material 4 is polyurethane foam, which can reduce air convection, prevent heat loss, enhance thermal insulation performance, reduce local stress and increase overall stability. The filling material 4 can further optimize sound wave reflection and absorption and improve noise reduction effect.

[0021] It should be noted that the first thermal break strip 1 is made of PA66 material, which has good heat resistance, corrosion resistance, and mechanical strength. Its coefficient of thermal expansion is similar to that of aluminum alloy and other door and window materials, which can maintain stable performance under different temperature conditions, effectively prevent heat transfer, and have a significant thermal insulation effect. At the same time, PA66 thermal break strips also have good anti-aging properties, which can extend the service life of doors and windows, and are often used in mid-to-high-end door and window products.

[0022] It should be noted that the first fin 5 and the second fin 6 can increase the contact area between the insulation strip and the air, forming more air chambers. These air chambers can effectively prevent heat conduction because air has poor thermal conductivity and can play a role in heat insulation. The multi-cavity finned insulation strip can divide the insulation layer into multiple equivalent cavities, some of which are equivalent dense cavities, further enhancing the heat insulation capacity and making the thermal insulation performance significantly improved compared to conventional insulation strips.

[0023] Please see Figure 1 In this embodiment, the outer surfaces of both the first heat insulation strip 1 and the second heat insulation strip 2 are provided with a covering layer, and the thickness of the covering layer is 1 mm.

[0024] The outer covering is made of PE film, which effectively reduces heat conduction in doors and windows, reduces heat exchange between indoors and outdoors, helps maintain a stable indoor temperature, reduces energy consumption of air conditioning, heating and other equipment, and achieves energy saving. It fits tightly with the door and window frame, effectively preventing air infiltration and rainwater leakage, improving the airtightness and watertightness of doors and windows, and blocking dust and noise to create a quiet and clean indoor environment. The outer covering has good anti-aging and anti-ultraviolet properties, which can extend the service life of the thermal insulation strip and maintain stable performance during long-term use, making it less prone to deformation and embrittlement.

[0025] The working principle of the above embodiments is as follows:

[0026] First, the staff installs the first thermal insulation strip 1 inside the door and window. During the installation process, the first fin 5 and the second fin 6 are snapped together and sealed with the door and window. When the gap inside the door and window is too large, the first thermal insulation strip 1 and the second thermal insulation strip 2 can be spliced ​​together. At this time, the filler 4 is filled into the gap between the first thermal insulation strip 1 and the second thermal insulation strip 2. This can reduce air convection, prevent heat loss, enhance thermal insulation performance, reduce local stress and increase overall stability. The filler 4 can further optimize sound wave reflection and absorption, and improve noise reduction effect.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
