Description

Technical Field

[0001] This utility model relates to the field of door and window structure technology, and more specifically, to a door and window thermal insulation profile. Background Technology

[0002] Both strip-insulated aluminum profiles and cast-in-place insulated aluminum profiles on the market work by using thermal break strips made of polymer materials (commonly PA66 and GF25) to block the heat conduction path inside the aluminum profile. Traditional strip-insulated aluminum profiles use a relatively long thermal break strip between two aluminum profiles, first cutting a tooth at the thermal break head, then rolling the strip through to completely isolate the indoor and outdoor profiles. This method achieves insulation performance close to the material's physical limits. There is an urgent market demand for a new type of insulated profile that can significantly improve insulation performance while also being economical and maintainable. Utility Model Content

[0003] Based on this, in order to solve the problem of insufficient thermal insulation performance of traditional through-type thermal insulation aluminum profiles, this utility model provides a thermal insulation profile for doors and windows, the specific technical solution of which is as follows: A door and window thermal insulation profile includes an outer frame, an inner frame, and at least two thermal insulation strips respectively snapped between the outer frame and the inner frame. The outer frame has a watertight cavity, the inner frame has an airtight cavity, and the thermal insulation strips have a thermal insulation cavity. A thermal insulation cavity is formed at the gap between the outer frame and the inner frame in cooperation with the thermal insulation strips. The thermal insulation cavity is filled with a filler material.

[0004] The aforementioned window and door insulation profiles, through the adoption of a multi-cavity structure, form a thermal break structure consisting of three parts: a watertight cavity (outdoor), a thermal insulation cavity (middle), and an airtight cavity (indoor), which can better improve thermal insulation performance. Among them, the longer the thermal break strip, the stronger the thermal insulation performance (thermal break strips with thermal insulation cavities are even more effective). In addition, the thermal insulation cavity is filled with a filler material, which can be appropriately adjusted according to the size of the thermal insulation cavity to meet diverse needs. Under the premise of installing the same thermal break strip, adding filler material can reduce energy consumption and also provide sound insulation.

[0005] Furthermore, the outer frame is provided with a plurality of first card slots, and the inner frame is provided with a plurality of second card slots, wherein the openings of the first card slots and the openings of the second card slots are arranged facing each other.

[0006] Furthermore, the number of the first slots and the number of the second slots are the same and correspond one-to-one, and the two ends of the heat insulation strip are detachably snapped onto the first slot and the second slot, respectively.

[0007] Furthermore, there are multiple watertight cavities, which are spaced apart.

[0008] Furthermore, there are multiple airtight cavities, which are spaced apart.

[0009] Furthermore, there are multiple heat insulation cavities, which are spaced apart.

[0010] Furthermore, the filling material is sound-insulating and heat-insulating cotton. Attached Figure Description

[0016] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0017] like Figures 1-3 As shown, a door and window thermal insulation profile according to one embodiment of the present invention includes an outer frame 1, an inner frame 2, and at least two thermal insulation strips 3 respectively snapped between the outer frame 1 and the inner frame 2. A watertight cavity 4 is formed inside the outer frame 1, an airtight cavity 5 is formed inside the inner frame 2, and a thermal insulation cavity 6 is formed inside the thermal insulation strips 3. A thermal insulation cavity 7 is formed at the gap between the outer frame 1 and the inner frame 2 in cooperation with the thermal insulation strips 3. The thermal insulation cavity 7 is filled with a filling material 8.

[0018] The aforementioned window and door insulation profiles, through the adoption of a multi-cavity structure, form a thermal break structure consisting of three parts: a watertight cavity 4 (outdoor), a thermal insulation cavity 7 (middle), and an airtight cavity 5 (indoor), which can better improve thermal insulation performance. Among them, the longer the thermal insulation strip 3, the stronger the thermal insulation performance (the thermal insulation strip 3 with the thermal insulation cavity 6 is even better). In addition, the thermal insulation cavity 7 is filled with a filler material 8. The filler material 8 can be appropriately adjusted according to the size of the thermal insulation cavity 7 to meet diverse needs. Under the premise of installing the same thermal insulation strip 3, adding filler material 8 can reduce energy consumption and also provide sound insulation.

[0019] like Figure 1 As shown, in one embodiment, the outer frame 1 is provided with a plurality of first slots 11, and the inner frame 2 is provided with a plurality of second slots 21, with the openings of the first slots 11 and the openings of the second slots 21 facing each other.

[0020] In one embodiment, the number of first slots 11 and the number of second slots 21 are the same and correspond one-to-one. The two ends of the heat insulation strip 3 are detachably snapped onto the first slots 11 and the second slots 21, respectively, which facilitates the installation and removal of the heat insulation strip 3.

[0021] like Figure 3 As shown, in one embodiment, there are multiple watertight cavities 4, which are spaced apart.

[0022] like Figure 3 As shown, in one embodiment, there are multiple airtight cavities 5, which are spaced apart.

[0023] like Figure 2 As shown, in one embodiment, there are multiple heat insulation cavities 6, which are spaced apart.

[0024] Depending on the cross-sectional size of different window and door insulation profiles, the number of cavities can be adjusted to form a multi-cavity structure, such as the above-mentioned multiple watertight cavities 4, multiple airtight cavities 5, or multiple insulation cavities 6, which helps to ensure and improve the overall thermal insulation performance of window and door insulation profiles.

[0025] Preferably, the filling material 8 is sound-insulating and heat-insulating cotton. By using sound-insulating and heat-insulating cotton as filling material, noise can be effectively reduced, and energy exchange caused by air convection in the heat insulation cavity 7 can be greatly reduced, thus reducing energy consumption, improving heat insulation performance, and protecting the environment.

[0026] Installation method of sound insulation and heat insulation cotton: After the door and window heat insulation profiles are completed through conventional processes such as cutting, inserting adhesive strips, and rolling, the sound insulation and heat insulation cotton is cut into sections according to the length of the door and window heat insulation profiles. After the cutting is completed, the sound insulation and heat insulation cotton is manually inserted into the heat insulation cavity 7 to be filled before assembly.

[0027] 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.

[0028] 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.
