Description

Technical Field

[0001] This utility model relates to the field of thermal insulation technology for thermally broken aluminum doors and windows, and in particular to an integrated thermal insulation strip and a thermally broken aluminum profile containing the strip. Background Technology

[0002] Thermally broken aluminum profiles are widely used in the building doors and windows industry due to their excellent thermal insulation performance. As the core component of thermally broken aluminum profiles, the structural design of the thermal break strip directly affects the overall performance of the profile, including thermal insulation, structural strength, waterproofing, and moisture resistance.

[0003] Currently, most thermal break strips used in thermally broken aluminum profiles on the market are of a split structure, meaning the upper and lower strips are assembled using simple connectors. This assembly method is not only cumbersome but also results in low connection strength. In terms of structural strength, the middle connecting part of existing thermal break strips often lacks sufficient support, making them prone to deformation or breakage under external forces. This is especially problematic in high-rise buildings where windows and doors experience significant wind pressure; existing thermal break strips often fail to meet the high-strength structural requirements, posing certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated thermal insulation strip and a thermally broken aluminum profile containing the same, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides an integrated thermal insulation strip, comprising:

[0007] The upper and lower strips extend along the length of the thermal break strip, and both ends are provided with protrusions that connect to the thermally broken aluminum profile.

[0008] The intermediate connector includes two partitions that are distributed on the left and right and arranged in parallel. The two partitions, the upper strip, and the lower strip enclose an intermediate chamber. An X-shaped frame is provided in the intermediate chamber. The four sides of the X-shaped frame are connected to the four corners of the intermediate chamber to divide the intermediate chamber into four independent chambers with triangular cross sections.

[0009] The connection between the upper strip, lower strip, two partitions and X-shaped frame is a one-piece extrusion molding, and the material is nylon 66 with 25% glass fiber, which is used for one-piece extrusion molding to form a one-piece structure.

[0010] The central intersection of the X-shaped frame in this technical solution forms a stable support point, which can evenly distribute external forces to the walls of the four independent chambers. When the thermal insulation strip is subjected to compression, tension, or bending forces from the thermally broken aluminum profile, the X-shaped frame resists deformation through its own triangular stability principle. Compared with an undivided single central chamber, the structure's resistance to deformation is effectively improved, significantly enhancing the reliability of the overall connection between the thermal insulation strip and the thermally broken aluminum profile. Furthermore, the four independent chambers significantly reduce heat transfer from air convection; the airflow range of each independent chamber is restricted, reducing the intensity of thermal convection and slowing down the diffusion rate of heat within the chambers. Moreover, after the X-shaped frame divides the central chamber, the natural frequencies of the air columns in the four independent chambers are different. When external sound waves enter, different chambers resonate and absorb sound waves of different frequencies, especially effectively blocking mid-to-high frequency noise (such as traffic and human voices).

[0011] As an extension of the above scheme, the independent chambers include an upper chamber and a lower chamber arranged symmetrically vertically, and a left chamber and a right chamber arranged symmetrically horizontally. The symmetrical arrangement of the independent chambers vertically and horizontally allows the thermal insulation strip to evenly distribute stress when under load, avoiding deformation caused by excessive local stress due to structural asymmetry.

[0012] As an extension of the above solution, it also includes a heat insulation chamber located on the side of the partition away from the X-shaped frame. This heat insulation chamber is formed by the outer thermally broken aluminum profile surface, the upper and lower strips and their protrusions on the upper and lower sides, and the partition. Combined with the intermediate chamber, this ensures that heat transfer between the indoor and outdoor sides must proceed through the heat insulation chamber – intermediate chamber – heat insulation chamber path, increasing the heat insulation path and area of ​​the heat insulation strip, further blocking heat transfer and improving the overall heat insulation effect.

[0013] As an extension of the above solution: the lower strip or the upper strip has a reinforcing chamber on the side away from the intermediate connector. The reinforcing chamber contains reinforcing ribs, which are vertically arranged to divide the reinforcing chamber into a left reinforcing chamber and a right reinforcing chamber. The reinforcing chamber and the internal reinforcing ribs enhance the structural strength of the lower or upper strip, making it less prone to deformation or breakage under external forces. In particular, it improves the load-bearing capacity of the thermal break strip at the connection point with the thermally broken aluminum profile, ensuring the reliability of the connection.

[0014] As an extension of the above solution: the X-shaped frame has airflow holes at its central intersection, and these airflow holes are spaced apart along the length of the insulation strips. Each airflow hole includes a vertical hole that penetrates through and connects the upper and lower chambers. The upper or lower strip has a first, coaxial mounting hole corresponding to the vertical hole. An airflow control valve is installed on the first mounting hole to block or open the vertical hole. The airflow holes at the central intersection of the X-shaped frame, along with the corresponding first mounting holes and airflow control valves, allow for control of airflow between the upper and lower chambers as needed. By adjusting the airflow control valves, the air conditions within the chambers can be flexibly adjusted under different environmental conditions, optimizing the insulation effect.

[0015] As an extension of the above solution, the airflow hole also includes a horizontal through-hole connecting the left and right chambers. One of the partitions has a second, coaxial mounting hole corresponding to the axis of the horizontal through-hole. An airflow control valve is installed on the second mounting hole to block or open the horizontal through-hole. The horizontal through-hole, the corresponding second mounting hole, and the airflow control valve enable airflow control between the left and right chambers. Used in conjunction with the vertical through-hole, it allows for more comprehensive adjustment of airflow in the intermediate chamber, further enhancing the adaptability of the thermal insulation strip to different environments.

[0016] As an extension of the above solution: the airflow control valve includes a pressure ring, a valve body, and a valve core. The pressure ring is fixedly fitted onto the first and / or second mounting holes. The inner side of the pressure ring and the outer side of the valve body are provided with mounting threads. The valve body is screwed into the pressure ring and fixed via the mounting threads, with one end containing the valve core extending into an independent chamber. The valve core moves closer to or further away from the vertical or horizontal hole along the corresponding hole axis within the valve body to control the blocking or opening of the vertical or horizontal hole. The pressure ring and mounting threads facilitate the disassembly and maintenance of the valve body.

[0017] As an extension of the above solution: the valve body has a cylindrical structure with a central sliding cavity. The valve core is disposed in the sliding cavity, and an elastic element is provided between the bottom end of the valve core and the bottom wall of the sliding cavity. A permanent magnet is provided at the bottom end of the valve core, and an electromagnetic coil is provided on the bottom wall of the sliding cavity. By controlling the on and off of the electromagnetic coil, the valve core is moved, thereby blocking or opening the vertical and horizontal holes and regulating the airflow in the intermediate chamber.

[0018] As an extension of the above solution: the valve core is made of rubber and has a tapered tip. In its natural state, under the force of the elastic element, the tip of the valve core tightly fits against the airflow hole on the X-shaped frame. This improves the sealing performance of the valve core against the airflow hole and reduces air leakage. In its natural state, the force of the elastic element ensures that the valve core fits tightly against the airflow hole, guaranteeing the reliability of the closed state.

[0019] On the other hand, this utility model also provides a thermally broken aluminum profile, including an integrated thermal insulation strip as described above. This utility model can improve the overall performance of thermally broken aluminum profiles, such as structural stability and thermal insulation properties, and expand the application range of thermally broken aluminum profiles.

Detailed Implementation

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional 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] In the description of this utility model, if there are words such as "several", they mean one or more, "multiple" means two or more, "greater than", "less than", "exceeding" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 5 The following are several embodiments of a one-piece thermal insulation strip and a thermally broken aluminum profile containing the present invention.

[0032] like Figure 1 As shown, an embodiment of this utility model provides a one-piece thermal insulation strip, comprising:

[0033] The upper strip 100 and the lower strip 200 extend along the length of the thermal break strip, and both ends are provided with protrusions 300 that connect to the thermal break aluminum profile.

[0034] The intermediate connector 400 includes two partitions 410 arranged horizontally and parallel to each other. The two partitions 410, the upper strip 100, and the lower strip 200 enclose an intermediate chamber. An X-shaped frame 420 is provided in the intermediate chamber. The four ends of the X-shaped frame 420 are connected to the four corners of the intermediate chamber to divide the intermediate chamber into four independent chambers with triangular cross sections.

[0035] The connection between the upper strip 100, the lower strip 200, the two partitions 410 and the X-shaped frame 420 is a one-piece extrusion molding.

[0036] In this embodiment, the upper strip 100 is connected to the top of the two partitions 410, and the lower strip 200 is connected to the bottom of the two partitions 410. The upper strip 100, the lower strip 200, and the two partitions 410 together form an intermediate chamber. The thickness of the upper strip 100 and the lower strip 200 is 1-2 mm, the thickness of the partitions 410 is 1-1.5 mm, and the thickness of the X-frame is 1-1.5 mm. The connection between the upper strip 100, the lower strip 200, the partitions 410, and the X-frame 420 is integrally formed using nylon 66 with 25% glass fiber through integral extrusion molding, forming a one-piece structure. This embodiment adopts an integral and integrally extruded design, eliminating the assembly process of a split structure and improving production efficiency. Meanwhile, the one-piece molding makes the connection between the upper strip 100, the lower strip 200, the two partitions 410 and the X-shaped frame 420 more solid, which can effectively resist thermal expansion and contraction stress and external forces, and enhance the structural stability and service life of the heat insulation strip.

[0037] In this embodiment, the central intersection of the X-shaped frame forms a stable support point, which can evenly distribute external forces to the walls of the four independent chambers. When the thermal break strip is subjected to compression, tension, or bending forces from the thermally broken aluminum profile, the X-shaped frame resists deformation through its own triangular stability principle. For example, under the lateral pressure generated when doors and windows are closed, the X-shaped frame can effectively prevent the central chamber from collapsing or twisting. Compared with an undivided single central chamber, the structural resistance to deformation is effectively improved, significantly enhancing the reliability of the overall connection between the thermal break strip and the thermally broken aluminum profile. Furthermore, the four independent chambers significantly reduce heat transfer caused by air convection. The airflow range of each independent chamber is restricted, the intensity of thermal convection is reduced, and the diffusion rate of heat within the chamber is slowed down. Simulation tests show that, under the same conditions, the thermal insulation coefficient (K value) of the four independent chambers divided by the X-shaped frame is reduced by 0.5-1.0 W / (m²・K) compared to a single chamber, resulting in a significant improvement in thermal insulation performance.

[0038] Furthermore, in this embodiment, the X-shaped frame divides the central chamber, resulting in four independent chambers with different natural frequencies of air columns. When external sound waves are introduced, the different chambers resonate and absorb sound waves of different frequencies, with a particularly significant blocking effect on mid-to-high frequency noise (such as traffic and human voices). The X-shaped frame can reflect and scatter sound waves, causing the sound wave energy to continuously attenuate during propagation. Compared with a single central chamber, the sound insulation can be improved by 3-5 decibels, thus improving the overall sound insulation performance of doors and windows.

[0039] In an optional embodiment, such as Figure 2 As shown, the independent chambers include an upper chamber 430 and a lower chamber 440 arranged symmetrically vertically, and a left chamber 450 and a right chamber 460 arranged symmetrically horizontally. The symmetrical arrangement of the independent chambers vertically and horizontally allows the thermal insulation strip to evenly distribute stress when under load, avoiding deformation caused by excessive localized stress due to structural asymmetry. Simultaneously, the symmetrical structure facilitates manufacturing and processing, and also helps ensure the stability of the connection between the thermal insulation strip and the thermally broken aluminum profile.

[0040] In an optional embodiment, such as Figure 1 As shown, the integrated thermal insulation strip also includes a thermal insulation chamber 470, which is located on the side of the partition 410 away from the X-shaped frame 420. This thermal insulation chamber is formed by the outer thermally broken aluminum profile surface, the upper and lower strips and their protrusions on the upper and lower sides, and the partition. Combined with the intermediate chamber, heat transfer between the indoor and outdoor sides must proceed through the thermal insulation chamber-intermediate chamber-thermal insulation chamber path, increasing the thermal insulation path and area of ​​the thermal insulation strip, further blocking heat transfer and improving the overall thermal insulation effect.

[0041] In an optional embodiment, such as Figure 2As shown, the lower strip 200 or the upper strip 100 has a reinforcing chamber 500 on the side away from the intermediate connector. The reinforcing chamber 500 contains reinforcing ribs 510, which are vertically arranged to divide the reinforcing chamber 500 into a left reinforcing chamber and a right reinforcing chamber. The reinforcing chamber and the internal reinforcing ribs enhance the structural strength of the lower or upper strip, making it less prone to deformation or breakage under external forces. In particular, it improves the load-bearing capacity of the thermal break strip at the connection point with the thermally broken aluminum profile, ensuring the reliability of the connection.

[0042] In an optional embodiment, such as Figure 3 As shown, the X-shaped frame 420 has an airflow hole 480 at the center intersection. The airflow holes 480 are arranged at intervals along the length of the heat insulation strip. The airflow hole 480 includes a vertical hole that is vertically through and connects the upper chamber 430 and the lower chamber 440. The upper strip 100 or the lower strip 200 has a first assembly hole coaxial with the hole axis corresponding to the vertical hole. An airflow control valve 600 is provided on the first assembly hole for blocking or opening the vertical hole.

[0043] In an optional embodiment, such as Figure 4 As shown, the airflow hole 480 also includes a horizontal through hole that connects the left chamber 450 and the right chamber 460. A second assembly hole is provided on a partition 410 corresponding to the axis of the horizontal hole. An airflow control valve 600 is provided on the second assembly hole for blocking or opening the horizontal hole.

[0044] It should be noted that when the two optional embodiments are implemented simultaneously, the vertical holes and the horizontal holes do not intersect or interfere with each other. Similarly, the vertical holes only penetrate the upper and lower chambers and do not affect the left and right chambers. The horizontal holes only penetrate the left and right chambers and do not affect the upper and lower chambers. The airflow holes are arranged at intervals along the length of the heat insulation strip. They can be arranged at equal intervals, and the spacing can be set according to the actual usage requirements. Furthermore, when one of the airflow holes is set as a vertical hole, the adjacent airflow holes can be arranged as horizontal holes, forming a horizontal-vertical-horizontal-vertical arrangement.

[0045] In this embodiment, the airflow holes at the center intersection of the X-shaped frame, along with the corresponding first mounting holes and airflow control valve, can control the airflow between the upper and lower chambers as needed. By adjusting the airflow control valve, the air conditions within the chambers can be flexibly adjusted under different environmental conditions to optimize the insulation effect. For example, in spring and autumn or in some comfortable weather, high insulation performance is not required to block heat, and air conditioning or heating is not necessary, but it is necessary to keep the indoor air fresh and avoid stuffiness or dampness caused by completely closed doors and windows. Opening the vertical holes promotes airflow between the chambers, and the passage of heat through the insulation strip allows a small amount of heat to be transferred through the insulation strip (such as the moderate transfer of heat from the outdoor sun into the room, or the dissipation of heat from slightly stuffy indoor air through the insulation strip). Combined with natural ventilation through door and window gaps, this maintains a basic balance between indoor and outdoor temperatures and avoids a feeling of indoor confinement caused by complete insulation. In winter, the airflow holes can be closed to reduce heat loss, or in summer, the airflow holes can be closed to prevent outdoor heat from intruding and affecting indoor cooling.

[0046] The horizontally positioned holes, along with the corresponding second mounting holes and airflow control valve, enable airflow control between the left and right chambers. Used in conjunction with the vertical holes, they allow for more comprehensive adjustment of airflow in the intermediate chamber, further enhancing the adaptability of the thermal insulation strip to different environments. This is particularly beneficial in spaces such as kitchens, bathrooms, and basements, where high humidity due to water usage or damp conditions can lead to excessive temperature differences on both sides of the thermal insulation strip if the insulation performance is too high. This causes moisture to condense on the strip's surface, potentially leading to corrosion and mold growth over time. By using the airflow control valve to reduce the insulation performance within the chamber, heat transfer within the thermal insulation strip becomes smoother, reducing the temperature difference and minimizing condensation conditions, thus preventing damage to the window and door structure from condensation.

[0047] Compared to traditional thermal insulation strips, their cavity structure design is relatively simple, making it impossible to flexibly adjust the airflow within the cavity according to different seasons and indoor-outdoor temperature differences, resulting in poor adaptability. This embodiment controls the airflow within the cavity by opening and closing an airflow control valve based on different seasons, indoor-outdoor temperature differences, or environmental conditions. This allows for flexible responses to different climatic conditions, enhancing the adaptability of the thermal insulation strip and solving the problem that existing thermal insulation strips cannot adjust their insulation methods according to environmental changes.

[0048] In an optional embodiment, such as Figure 5 As shown, the airflow control valve 600 includes a pressure ring 610, a valve body 620, and a valve core 630. The pressure ring 610 is fixedly fitted onto the first mounting hole and / or the second mounting hole. The inner side of the pressure ring 610 and the outer side of the valve body 620 are provided with mounting threads. The valve body is screwed into the pressure ring 610 through the mounting threads and fixed, with one end containing the valve core 630 extending into an independent chamber. The valve core 630 in the valve body 620 moves closer to or further away from the vertical or horizontal hole along the corresponding hole axis direction to control the blocking or opening of the vertical or horizontal hole.

[0049] In this embodiment, the integrated heat insulation strip of one or more of the above optional embodiments is produced by an integral extrusion molding process. Then, the position of the airflow hole is set according to the actual use requirements, such as setting an airflow hole every 10mm. Then, holes are made according to the axial direction of the horizontal or vertical hole to obtain the first assembly hole and / or the second assembly hole and the corresponding horizontal and / or vertical hole. The first assembly hole and / or the second assembly hole are fixed by a pressure ring. Then, the valve body is screwed into the pressure ring and fixed. The opening or blocking of the horizontal and / or vertical holes can be controlled by controlling the sliding of the valve core in the valve body. The pressure ring and the assembly thread facilitate the disassembly and maintenance of the valve body.

[0050] To better understand the opening and closing of the airflow control valve in the above embodiments, in an optional embodiment, such as Figure 5 As shown, the valve body 620 has a cylindrical structure with a sliding cavity 621 in the center. The valve core 630 is disposed in the sliding cavity 621, and an elastic element 622 is provided between the bottom end of the valve core 630 and the bottom wall of the sliding cavity 621. A permanent magnet 631 is provided at the bottom end of the valve core 630, and an electromagnetic coil 623 is provided on the bottom wall of the sliding cavity 621.

[0051] In this embodiment, when the electromagnetic coil is energized and drives the valve core to open to the position, the permanent magnet of the valve core and the iron core of the electromagnetic coil (or another permanent magnet is set at the corresponding position on the bottom wall of the sliding cavity) generate a stable attraction force. Even if the power is cut off, the attraction force can overcome the elastic force of the elastic element and maintain the valve core in the open airflow hole state. If it is to be closed, simply pass a reverse current to the electromagnetic coil to generate a repulsive force, push the valve core to detach from the attraction, and the elastic element can be reset, providing an elastic force to push the top of the valve core to fit tightly against the airflow hole on the X-shaped frame.

[0052] This embodiment controls the energization and de-energization of the electromagnetic coil to move the valve core, thereby blocking or opening the vertical and horizontal holes and regulating the airflow in the intermediate chamber. It should be noted that this embodiment does not impose any restrictions on the energization settings of the electromagnetic coil. It can be integrated into a push-button switch on the thermally broken aluminum profile by connecting it in series with fine-diameter enameled wire. For example, a push-button mounting hole is opened on the inner side of the thermally broken aluminum profile, and the push-button switch is installed in this hole, allowing unified control of the energization and de-energization of the electromagnetic coil. The electromagnetic coil is wound with fine-diameter enameled wire (e.g., 0.1-0.5mm), with a small number of turns (tens to hundreds of turns) and a low resistance value (generally 10-100Ω). According to Ohm's law, under low-voltage drive (commonly 3-12V DC power supply), the operating current is usually only in the milliampere range (e.g., with 3V power supply, the current of a 10Ω coil is about 0.3A, but the actual current of a miniature coil is often 50-500mA), and the power of a single coil is often between 0.15-6W. Therefore, the energization of the electromagnetic coil and its electrical connection settings can be achieved using existing technologies. For example, the electromagnetic coil can be controlled by an external controller (such as a microprocessor). The controller can receive environmental signals detected by temperature sensors, etc. When the ambient temperature is higher than 30℃ or lower than 10℃, it controls the electromagnetic coil to de-energize and close the airflow holes; when the temperature is between 10℃ and 30℃, and there is no need to turn on the underfloor heating or air conditioning indoors, it controls the electromagnetic coil to energize and open the corresponding airflow holes.

[0053] In an optional embodiment, such as Figures 3 to 5 As shown, the valve core 630 is made of rubber and has a tapered tip. In its natural state, under the force of the elastic element 622, the tip of the valve core 630 tightly fits against the airflow hole 480 on the X-shaped frame 420. The rubber material of the valve core and the tapered tip design improve the sealing performance of the valve core to the airflow hole and reduce air leakage. In its natural state, the force of the elastic element ensures that the valve core tightly fits against the airflow hole, guaranteeing the reliability of the closed state.

[0054] On the other hand, this utility model also provides a thermally broken aluminum profile, including an integrated thermal insulation strip as described in one or more of the above-mentioned optional embodiments. This utility model can improve the overall performance of thermally broken aluminum profiles, such as structural stability and thermal insulation properties, and expand the application range of thermally broken aluminum profiles.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
