Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic co-extruded window frame technology, and in particular to an aluminum-plastic co-extruded window frame with a multi-cavity structure. Background Technology

[0002] Currently, aluminum-plastic co-extruded profiles are commonly used as window frame materials in buildings. This type of profile typically consists of an aluminum alloy load-bearing layer and a plastic inner lining layer, bonded together through a co-extrusion process. It features a multi-cavity structure internally to enhance overall thermal insulation, sound insulation, and strength. This multi-cavity design helps to mitigate heat and noise transmission and reduces the overall weight of the window frame, making it widely used in energy-efficient buildings and high-end residences.

[0003] However, existing aluminum-plastic co-extruded window frames are prone to water leakage or condensation due to poor sealing during long-term use. Users often only notice this when mold or water stains appear indoors, lacking early warning and visual inspection methods. Utility Model Content

[0004] Therefore, it is necessary to provide an aluminum-plastic co-extruded window frame with a multi-cavity structure to address the problem that existing aluminum-plastic co-extruded window frames are prone to water leakage or condensation due to poor sealing during long-term use, but users often only notice it when mold or water stains appear indoors, lacking early warning and intuitive detection methods.

[0005] A multi-cavity co-extruded aluminum-plastic window frame includes: an aluminum window shell with an inner cavity inside; and a multi-cavity protective mechanism, wherein a telescopic multi-cavity protective mechanism for displaying and protecting the aluminum window shell is disposed inside the inner cavity; wherein the multi-cavity protective mechanism includes a protective cavity fixedly installed inside the inner cavity, a display component is disposed on the outside of the protective cavity, and a protective component is disposed inside the protective cavity.

[0006] The display assembly includes a first display window and a second display window fixedly installed on the outside of the aluminum window shell. A water leakage detection strip is provided on one side of the first display window, and the water leakage detection strip is located inside the inner cavity and fixedly connected to the inner cavity.

[0007] A temperature measuring strip is provided on one side of the second display window, and the temperature measuring strip is fixedly connected to the inside of the cavity.

[0008] An injection port is fixedly installed on both sides of the inner cavity, and the two injection ports are located on both sides of the protective cavity.

[0009] The leakage detection strip is located on top of the temperature measuring strip, which is located on top of the two injection ports.

[0010] The temperature measuring strip has a connecting port at the top of both injection ports, and the connecting port is strip-shaped.

[0011] The protective assembly includes two fixed cavities fixedly installed inside the protective cavity, and multiple flow-blocking strips are fixedly installed inside each of the two fixed cavities.

[0012] All of the flow-blocking strips are designed with a slightly raised ridge shape, and multiple reinforcing ribs are fixedly installed between the two fixed cavities.

[0013] Beneficial effects 1. By installing a display component on the outside of the protective cavity, the window frame can visually change color to indicate water leakage or abnormal temperature. Users can monitor the status and receive early warnings without disassembling the window frame, avoiding the problem of traditional window frames relying on delayed phenomenon recognition. The protective cavity is equipped with a protective component consisting of multiple chambers and airflow-deflecting parts, which deflects and redirects airflow, reducing convective heat transfer, improving insulation performance, and overcoming the shortcomings of insufficient insulation performance of a single air layer. 2. The flow-blocking strip forces the airflow path entering the fixed cavity to deflect and bend, thereby significantly reducing the convective heat transfer effect of the air inside the cavity and improving the thermal insulation performance of the window frame. This not only improves the overall thermal and sound insulation effect of the multi-cavity structure, but also slows down the performance degradation during long-term use, ensuring the stability and durability of the window frame.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes an aluminum-plastic co-extruded window frame with a multi-cavity structure.

[0019] In one embodiment, an aluminum-plastic co-extruded window frame with a multi-cavity structure includes: an aluminum window shell 100, the interior of which is provided with an inner cavity 200; and a multi-cavity protection mechanism 300, a telescopic multi-cavity protection mechanism 300 for displaying protection of the aluminum window shell 100 disposed inside the inner cavity 200; wherein, the multi-cavity protection mechanism 300 includes a protection cavity 310 fixedly installed inside the inner cavity 200, a display component 320 disposed on the outer side of the protection cavity 310, and a protection component 330 disposed inside the protection cavity 310.

[0020] In this embodiment, by setting a display component 320 on the outside of the protective cavity 310, the window frame can visually indicate water leakage or temperature abnormalities through a color change on the display window. Users can achieve visual monitoring of water leakage and temperature conditions without disassembly, avoiding the shortcomings of traditional window frames that rely on visual observation of mold, water stains, and other delayed phenomena to detect problems. This enables early warning of water leakage and condensation risks. The protective cavity 310 is equipped with a protective component 330, which consists of multiple chambers. Different chambers are equipped with airflow turbulence components, which cause the airflow path to form bypass or deflection, significantly reducing the heat transfer effect of air convection within the cavity, improving thermal insulation performance, and solving the problem of insufficient thermal insulation performance caused by a single air layer in the cavity. It should be noted that existing aluminum-plastic co-extruded window frames typically include an aluminum window shell 100, a plastic liner, and a multi-cavity structure formed by the co-extrusion of the two. The aluminum window shell 100 mainly bears the structural load and wind pressure resistance, the plastic liner is used to improve heat insulation, sound insulation and corrosion resistance, and the multi-cavity structure further reduces the transmission of heat and noise through the air layer inside the cavity. The display component 320 serves only as a status indicator. It is small in size and has a fixed installation position, and has no adverse effect on the airtightness and structural strength of the window frame. The protective component 330 consists of multiple chambers and airflow-disrupting components, all located within the multi-chamber interior space. Its function is to optimize the airflow path and provide injectable space. It does not involve the direct interface between the window frame and the outside world, and therefore will not hinder the opening, closing, load-bearing capacity, or long-term use of the window frame.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the display assembly 320 includes a first display window 321 and a second display window 322 fixedly installed on the outside of the aluminum window shell 100. A water leakage detection strip 323 is provided on one side of the first display window 321. The water leakage detection strip 323 is located inside the inner cavity 200 and is fixedly connected to the inner cavity 200.

[0022] In this embodiment, when water seepage occurs inside the inner cavity 200 due to sealing failure, the water leakage detection strip 323 will change color after absorbing water. The user can directly observe the color change through the first display window 321, thereby promptly detecting potential water seepage hazards in the window frame and avoiding mold growth or structural damage to the window due to long-term water accumulation.

[0023] A temperature measuring strip 324 is provided on one side of the second display window 322, and the temperature measuring strip 324 is fixedly connected to the inside of the inner cavity 200.

[0024] In this embodiment, when the inner cavity 200 is in a low temperature or high temperature environment, the temperature measuring strip 324 will produce different color reactions according to the temperature change. The user can intuitively observe the temperature status of the window frame through the second display window 322, so as to take antifreeze measures in time in cold weather, or to adjust the sunshade and ventilation in hot weather, to avoid condensation and ice formation due to low temperature, or stuffiness in the room due to high temperature, thereby improving the comfort of living and the safety of window frame use. It should be noted that the leak detection strip 323 can be made of water-absorbing color-changing material or water-sensitive indicator strip, such as commonly used fiber paper tape containing water-sensitive dye or plastic sheet coated with color-developing layer, which will change from light color to dark color or from one color to another when it comes into contact with water, thus providing an intuitive leak indication. The temperature measuring strip 324 can be made of liquid crystal temperature measuring film, metal thermosensitive coating or thermosensitive color changing ink. It can display different color states when the temperature reaches different ranges. For example, the liquid crystal temperature measuring film can display blue, green and orange colors in sequence according to the temperature change in different ranges, so as to indicate the temperature range.

[0025] An injection port 326 is fixedly installed on both sides of the inner cavity 200, and the two injection ports 326 are located on both sides of the protective cavity 310 respectively.

[0026] In this embodiment, the injection port 326 is used to inject functional filling materials into different chambers of the protective cavity 310 after the window frame is installed or during use. For example, when it is necessary to improve the thermal insulation performance, closed-cell foam material can be injected through the injection port 326 to form a thermal insulation layer. When it is necessary to improve the sound insulation effect, sound-absorbing foam or fiber filler can be injected. Thus, the performance of the window frame can be flexibly adjusted according to different environments and user needs. After injection, the filling material is fixed inside the protective cavity 310 and will not affect the load-bearing strength and appearance structure of the window frame. This achieves the effect of optimizing the thermal insulation or sound insulation performance in the later stage without replacing the window frame.

[0027] The leak detection strip 323 is located on top of the temperature measuring strip 324, which is located on top of the two inlet ports 326.

[0028] In this embodiment, this layered arrangement ensures that the leak detection strip 323 is in preferential contact with the seeping or condensing water in the upper part of the inner cavity 200, thereby causing a timely color change reaction and providing a leak warning. The temperature measuring strip 324 is arranged below the leak detection strip 323, so it can accurately reflect the temperature change in the cavity without being directly affected by water, ensuring the stability and reliability of the temperature display.

[0029] The temperature measuring strip 324 has a connecting port 325 at the top of the two injection ports 326, and the connecting port 325 is strip-shaped.

[0030] In this embodiment, the connecting port 325 is used to connect different chambers after the filling material is injected into the injection port 326, so that the sound insulation foam or heat insulation foam can be evenly distributed inside the protective cavity 310, avoiding local accumulation or filling dead corners, and improving the overall filling effect and density.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the protective assembly 330 includes two fixed cavities 331 fixedly installed inside the protective cavity 310, and multiple flow-blocking strips 332 are fixedly installed inside each of the two fixed cavities 331.

[0032] In this embodiment, the flow-blocking strip 332 forces the airflow path entering the fixed cavity 331 to be bypassed and deflected, thereby significantly reducing the convective heat transfer effect of the air in the cavity and improving the heat insulation performance of the window frame. This not only improves the overall heat insulation and sound insulation effect of the multi-cavity structure, but also slows down the performance degradation during long-term use, ensuring the stability and durability of the window frame.

[0033] Multiple flow-blocking strips 332 are all designed with a slightly raised ridge shape, and multiple reinforcing ribs 333 are fixedly installed between the two fixed cavities 331.

[0034] In this embodiment, the micro-convex ridge-shaped flow-blocking strip 332, while ensuring unobstructed airflow within the cavity, forces the air to continuously generate disturbances and vortices during flow, slowing down the airflow velocity and lengthening the flow path. This significantly reduces the convective heat transfer effect, further improving the thermal insulation performance of the window frame. Simultaneously, the surface of the micro-convex ridge forms multiple refraction and reflection interfaces, which also weaken and attenuate noise propagation, enhancing sound insulation. The reinforcing rib 333, spanning between the two fixed cavities 331, effectively enhances the overall structural strength of the protective cavity 310, preventing cavity wall deformation or collapse after long-term stress or the injection of filling material. It also distributes external impact to a certain extent, ensuring the stability and durability of the window frame under high-intensity usage scenarios.

[0035] Working principle: The aluminum window shell 100 is fixedly installed at the building opening as an integral load-bearing outer shell. The inner cavity 200 forms a multi-cavity space inside the window frame. The multi-cavity protection mechanism 300 is integrally set in the inner cavity 200 and cooperates with the aluminum window shell 100. Exhaust gas or external ambient air first comes into contact with the outer surface of the aluminum window shell 100. Changes in internal temperature and humidity or water seepage will preferentially affect the protection cavity 310. A display component 320 is set on the outside of the protection cavity 310. The water leakage detection strip 323 corresponding to the first display window 321 will quickly absorb water and produce a color reaction when water seepage or condensation occurs. Users can intuitively identify the water leakage status from the outside, realizing early detection of poor sealing or water seepage risks. The temperature measuring strip 324 corresponding to the second display window 322 will show different colors in sequence when the ambient temperature reaches different ranges. Users can monitor the temperature changes of the environment where the window frame is located in real time, and thus take corresponding indoor adjustment measures. When users require further improvements in thermal insulation or sound insulation performance, closed-cell foam material or sound-absorbing foam can be injected into different chambers of the protective cavity 310 through the injection ports 326 located on both sides of the inner cavity 200. The injected material diffuses and flows between different chambers through the strip-shaped connecting port 325 located below the temperature measuring strip 324, achieving uniform distribution of the filling material and avoiding local accumulation or dead corners, thereby ensuring the stability of the thermal insulation or sound insulation effect. At the same time, the protective component 330 forms multiple fixed cavities 331 inside the protective cavity 310. Each fixed cavity 331 is provided with a flow-blocking strip 332 with a micro-convex ridge shape, which continuously disturbs and deflects the air inside the cavity during the flow process, reducing the intensity of convective heat transfer and enhancing the sound insulation effect. The reinforcing ribs 333 between two fixed cavities 331 further improve the strength and stability of the overall structure of the protective cavity 310, preventing cavity wall deformation under the action of the filling material or long-term use.
