Description

Technical Field

[0001] This utility model relates to the technical field of thermally broken aluminum profiles, specifically thermally broken aluminum profiles that enhance sound insulation. Background Technology

[0002] Thermally broken aluminum profiles, also known as thermally broken aluminum alloy profiles, thermally broken aluminum alloy profiles, thermally broken profiles, and thermally broken aluminum-plastic composite profiles, have superior performance compared to ordinary aluminum alloy profiles. Aluminum alloy is a metal and conducts heat relatively quickly, so when there is a large temperature difference between indoors and outdoors, aluminum alloy can become a "bridge" for heat transfer. However, if such materials are used to make doors and windows, their thermal insulation performance will be poor.

[0003] Thermally broken aluminum alloy is made by breaking the aluminum alloy in the middle and using a thermal break strip to connect the broken aluminum alloy into one piece. Plastic has a significantly lower thermal conductivity than metal, so heat is not easily transmitted through the entire material, thus improving the material's thermal insulation performance. This is what is meant by "thermally broken aluminum alloy". Traditional thermally broken aluminum alloy structures have poor sound absorption and insulation effects, which still need to be improved. Summary of the Invention

[0004] (a) Technical problems to be solved

Detailed Implementation

[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. 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.

[0028] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Please see Figures 1-5 The thermally broken aluminum alloy structure shown includes frame 1 and frame 2. An upper thermal insulation strip 3 and a lower thermal insulation strip 4 are installed between frame 1 and frame 2 to connect them and provide a certain degree of sound insulation and heat preservation. The upper thermal insulation strip 3 and lower thermal insulation strip 4 are made of PA66 nylon.

[0030] To further enhance the sound insulation of the entire thermally broken aluminum frame, a reflective corrugated surface 5 is provided on the inner side of frame 1, and two reflective plates 6 are also provided on frame 1, respectively located on the upper and lower sides of frame 1. A reflective corrugated surface 5 is also provided on the inner side of frame 2, and two reflective plates 7 are also provided on frame 2, respectively located on the upper and lower sides of frame 2.

[0031] When sound waves are transmitted to the undulating reflective corrugated surface 5, the sound waves are refracted in multiple directions, thereby achieving the purpose of continuously refracting and dissipating the energy of the sound waves in the frame 1 and the antibody 2, thus achieving the ability to insulate sound.

[0032] Specifically, the length of the two reflectors 6 is greater than half the height H of the frame 1, and a first sound-absorbing cotton 8 is provided between the two reflectors 6.

[0033] The length of the two reflectors 7 is greater than half the height D of the frame 2, and a second sound-absorbing cotton 9 is provided between the two reflectors 7.

[0034] A third sound-absorbing cotton 17 is also provided between the upper heat insulation strip 3 and the lower heat insulation strip 4.

[0035] In this embodiment, the first sound-absorbing cotton 8 and the second sound-absorbing cotton 9 can effectively absorb sound waves passing through the portion of the absorption reflector 6 and the second reflector 7, further reducing the transmission of sound waves. Similarly, the third sound-absorbing cotton 17 is also for the purpose of further absorbing sound waves. Furthermore, the first sound-absorbing cotton 8, the second sound-absorbing cotton 9, and the third sound-absorbing cotton 17 are all made of EPDM foam composite material.

[0036] Specifically, the side of frame 1 is provided with connecting groove 10 and connecting groove 21, the side of frame 2 is provided with connecting groove 312 and connecting groove 413, both sides of the upper heat insulation strip 3 are provided with connecting block 15, and both sides of the lower heat insulation strip 4 are provided with connecting block 216. The two connecting blocks 15 are respectively engaged in connecting groove 10 and connecting groove 312, and the connecting blocks 216 are respectively engaged in connecting groove 21 and connecting groove 413.

[0037] In this embodiment, in order to facilitate the connection of the upper heat insulation strip 3 and the lower heat insulation strip 4 with the frame 1 and the frame 2, a connecting block 15 is designed to engage with the connecting groove 10 and the connecting groove 21 respectively, and a connecting groove 312 and the connecting groove 14 are designed to engage with the connecting block 26 to achieve the connection.

[0038] Specifically, both reflector 6 and reflector 7 are provided with V-shaped grooves 18, and the V-shaped grooves 18 are evenly distributed on the sides of reflector 6 and reflector 7.

[0039] In this embodiment, the V-shaped groove 18 has a similar function to the reflective corrugated surface 5. By changing the reflection direction of the sound wave through the inclined V-shaped groove 18, the number of reflections of the sound wave in the frame is increased, so that most of the energy of the sound wave is lost in the frame, thereby achieving the purpose of sound insulation.
