Description

Technical Field

[0001] The utility model relates to the field of building exterior walls, in particular to a building exterior wall capable of automatically adjusting temperature. Background Art

[0002] Building exterior walls (building envelopes) are a crucial component of a building's structure, providing insulation, load-bearing, thermal insulation, waterproofing, and aesthetics. While the design and construction materials used for exterior walls vary significantly depending on climate, building type, and functional requirements, they generally must meet requirements such as structural load-bearing and earthquake resistance, thermal insulation, waterproofing, fire resistance, sound insulation, and aesthetics.

[0003] To achieve automatic temperature regulation, walls are often filled with phase-change materials. Phase-change materials undergo a solid-liquid phase transition within a certain temperature range, mitigating temperature fluctuations by absorbing or releasing latent heat during this phase change. However, in some regions or seasons, when sunlight intensity is high but the indoor temperature doesn't need to be lowered, the phase-change material may transform from solid to liquid under sunlight, absorbing heat from the surrounding wall. This process, in turn, transfers indoor heat to the phase-change material, further lowering the indoor temperature and making it difficult to meet insulation requirements. This is particularly true in high-latitude regions during winter or spring in the Northern Hemisphere, where sunlight intensity is uneven. The phase-change process within the wall's phase-change material can cause unexpected temperature fluctuations, negatively impacting the overall thermal comfort of the indoor environment. Furthermore, current building exterior walls are typically joined using a frame-type splicing method, where exterior wall panels are embedded in a metal frame, supported and secured by the frame structure, and then joined together using fixtures. However, this increases the time required for exterior wall installation and fails to meet the demand for rapid installation. Utility Model Content

DETAILED DESCRIPTION

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0033] like Figures 1 to 7 As shown, the building exterior wall can automatically adjust its temperature. The building exterior wall includes an inner wall 1, a frame 2, a cooling assembly 4, an outer wall 51, and a phase change material 6. The frame 2 is installed between the inner wall 1 and the outer wall 51, forming a closed hollow space for accommodating the phase change material 6. The phase change material 6 has the characteristic of absorbing and releasing heat in response to changes in ambient temperature. It can absorb external heat in high-temperature environments and release stored heat in low-temperature environments, thereby providing thermal insulation for the inner wall 1. The cooling assembly 4 includes a support frame 42, a cooling pipe 43, a bellows 45, and a connector 46. The support frame 42 is fixedly mounted on the inner wall 1 and is tightly connected to the cooling pipe 43. The two ends of the cooling pipe 43 extend outward through the frame 2, making it convenient to connect to the external cooling water system. The cooling water system includes an external water source and a water pump so that cooling water can be introduced into the cooling pipe 43 during high temperature seasons. In the present invention, the cooling water is groundwater, which further reduces the temperature of the phase change material 6. The bellows 45 are arranged at the connection between the two ends of the cooling pipe 43 and the connector 46, which can provide a flexible connection during the thermal expansion and contraction of the cooling pipe 43 caused by temperature changes, thereby avoiding deformation or damage to the component. The flange 41 is used to firmly connect the cooling component 4 to the outer wall structure to ensure the overall stability of the system. Through the above design, the temperature of the inner wall 1 can always be maintained within a comfortable range, effectively improving the energy efficiency of the building and reducing the energy consumption of air conditioning. At the same time, the system has a simple structure and is easy to maintain.

[0034] When the indoor temperature does not need to be further lowered, the phase change material 6 will still change from solid to liquid under the irradiation of sunlight. At this time, the phase change material 6 will absorb heat, causing the indoor temperature to drop further. Therefore, when the phase change material 6 does not need to absorb heat and is exposed to sunlight, the phase change material 6 in the building exterior wall needs to be cooled. A connector 46 is connected to an existing water pump (not shown in the figure) through a flange 41. The other end of the water pump is connected to an external water source. Then, the connector 46 at the other end is connected to a connector 46 on another building exterior wall through the flange 41. Then, the water pump transports cooling water to the cooling pipe 43. The cooling pipe 43 uniformly cools the phase change material 6 in the frame 2. This allows the phase change material 6 to be cooled when it needs to continue to absorb heat, thereby releasing heat and changing the phase change material back to a solid state. The water pump is controlled by an external temperature sensor. When the temperature of the building exterior wall needs to continue to drop, the phase change material 6 is cooled in the above manner, thereby realizing the automatic temperature adjustment function of the building exterior wall.

[0035] In this embodiment, the cooling assembly 4 of the building's exterior wall also includes fins 44. Fins 44 are made of copper, which accelerates cooling. Fins 44 are fixedly connected to cooling tubes 43, further enhancing the cooling effect. Fins 44 are evenly distributed across the surface of cooling tubes 43 and fixedly connected thereto. By increasing the surface area of ​​cooling tubes 43, the heat exchange efficiency between the cooling water and the phase change material 6 is improved. Under high temperature conditions, cooling water flows through cooling tubes 43 and removes excess heat. Fins 44 accelerate the cooling process of cooling tubes 43, allowing the phase change material 6 to cool rapidly, thereby maintaining a stable temperature in the interior wall 1.

[0036] The deformation temperature of the phase change material 6 can be changed by the cooling tube 43 and the fin 44 , so that the phase change material can absorb more heat, thereby automatically controlling the temperature of the building exterior wall.

[0037] In this embodiment, two limiting assemblies 3 are further provided to adjust and control the stability and installation position of the cooling assembly 4. The limiting assembly 3 includes a base 31, a slide 32, a limiting column 33, a block 34, a tension spring 35 and a bolt 36. The base 31 is fixedly connected to the side of the inner wall 1 close to the frame 2, and a turntable 37 is installed on its surface. A slide 32 is provided on the turntable 37, and two limiting columns 33 are embedded in the slide 32. The limiting columns 33 are fixedly connected to the blocks 34, and the blocks 34 can slide on the slide 32. The inner ends of the two blocks 34 are respectively fixedly connected to the two ends of the tension spring 35. The spring 35 provides a pulling force for the two blocks 34 to move closer to each other, so as to achieve the fixation of the limiting column 33 to the connector 46. The turntable 37 is threadedly connected to the bolt 36 through the provided through hole. The head of the bolt 36 contacts the base 31 to form a firm connection structure, ensuring the overall stability of the turntable 37 and its limiting assembly 3. The positioning assembly 3 allows for more precise installation and adjustment of the cooling assembly 4, adapting to the various angles of the cooling pipe 43 connection requirements. This prevents the cooling pipe 43 from being unable to connect when the cooling pipe 43 is installed in different positions on the exterior wall 51, further enhancing the overall stability and reliability of the building exterior wall system. Furthermore, this structural improvement significantly improves the structural stability and temperature control effectiveness of the automatic temperature-controlled building exterior wall, resulting in excellent performance.

[0038] When the angle of the connector 46 needs to be rotated, the two limit columns 33 are first driven to move by the tension spring 35, and the two limit columns 33 clamp the connector 46. Then the bolt 36 is removed from the turntable 37, and the turntable 37 is rotated. The limit columns 33 rotate with the turntable 37, and the limit columns 33 drive the connector 46 to rotate. The connector 46 drives one end of the bellows 45 to rotate. When the bellows 45 rotates to the required angle, the bolt 36 is inserted into the turntable 37, and then the two ends of the connector 46 are fixed by the flange 41.

[0039] In this embodiment, the connection structure between the inner wall 1 and the limiting assembly 3 is further optimized. Two limiting grooves 11 are provided on the side of the inner wall 1 close to the frame 2. These limiting grooves 11 are used to accommodate the base 31 of the limiting assembly 3, thereby improving the stability of the overall installation. A circular protrusion 12 is provided on the inner wall of each limiting groove 11 to play a positioning role. The base 31 is installed in the limiting groove 11 and is fixedly connected to the circular protrusion 12 in the limiting groove 11 through a tight fit, thereby achieving a stable installation of the base 31. This structural design ensures that the base 31 of the limiting assembly 3 is fixed more reliably on the inner wall 1.

[0040] In this embodiment, an exterior wall fixing assembly 5 is also provided for the rapid splicing of the exterior walls of a building. The exterior wall fixing assembly 5 includes a slider 52, a round rod 53, a ball bearing 54, a shift block 55, a spring 56, and a chute 57. The chute 57 is provided on the surface of the exterior wall 51 and is slidably connected to the slider 52, allowing the slider 52 to move along the chute 57. The slider 52 is fixedly connected to the round rod 53, and a ball bearing 54 is mounted on the end of the round rod 53. The ball bearing 54 can improve the stability and precision of the contact between the wedge block 9 and the ball bearing 54. At the same time, the slider 52 is also fixedly connected to the shift block 55, which is used to adjust the position of the slider 52 to facilitate the movement of the ball bearing 54 inside the exterior wall 51.

[0041] The two sides of the slider 52 are respectively fixedly connected with a spring 56, and the other end of the spring 56 is fixed to the inner walls of the two sides of the slide 57. The ball 54 is always inserted in the through hole, which helps to improve the stability of the exterior wall system.

[0042] By adding the exterior wall fixing assembly 5, the automatic temperature-controlled building exterior wall is more convenient to install and maintain, and has stronger earthquake resistance.

[0043] When the exterior walls of a building need to be spliced, the operator first places the exterior walls 51 of the two exterior walls of the building close to each other, and then the operator pulls the shift block 55 on the side adjacent to the first dovetail tenon 72 to enter the first dovetail groove 71. As the shift block 55 moves, the round rod 53 drives the ball 54 to move toward the interior of the exterior wall 51. After the ball 54 enters the interior of the exterior wall 51, the first dovetail tenon 72 on the second side wall 512 of one exterior wall 51 is inserted into the first dovetail groove 71 on the other first side wall 511. The first dovetail tenon 72 drives the wedge block 9 to move, and the wedge block 9 is located at the second side wall 512. The ball 54 in a dovetail groove 71 is pushed open, and the ball 54 drives the slider 52 to move through the round rod 53. At this time, the slider 52 presses the spring 56, and the spring 56 is in a compressed state. When the through hole on the surface of the first dovetail tenon 72 moves to correspond to the position of the ball 54, the spring 56 is no longer under pressure, and the spring 56 resets to push the ball 54 into the through hole. At this time, the first dovetail tenon 72 cannot move, and the operator loosens the shift block 55. Through the above transmission method, the other ball 54 can also be inserted into the through hole of the first dovetail tenon 72, thereby fixing the two outer walls 51 together.

[0044] The outer wall 51 is connected by dovetail joints and dovetail grooves, which enables operators to quickly splice multiple outer walls 51 without having to build them through a frame, thereby meeting the need for rapid construction of the outer wall 51.

[0045] In this embodiment, to enhance the structural stability of the exterior wall 51 and facilitate modular assembly, the first sidewall 511 of the exterior wall 51 is provided with a first dovetail groove 71, and the second sidewall 512 is provided with a mating first dovetail tenon 72. The size and shape of the first dovetail tenon 72 are precisely designed to securely fit into the first dovetail groove 71, forming a secure connection. This structure allows for rapid assembly of the building's exterior wall without the need for a metal frame, and the individual modules of the exterior wall 51 can be easily connected.

[0046] When adjacent exterior wall modules 51 are connected via dovetail joints and dovetail grooves, the structural integrity of the entire exterior wall 51 is effectively improved, and the structural strength of the joints is significantly enhanced, allowing it to withstand greater external pressure or deformation stress caused by temperature fluctuations. Furthermore, the self-locking effect of the dovetail joints and dovetail grooves prevents the exterior wall 51 from separating after assembly, enhancing the system's earthquake and wind resistance. This modular design also facilitates assembly and disassembly of the building's exterior walls, simplifying the construction process.

[0047] By adopting the above design, the automatic temperature-controlled building exterior wall has higher assembly stability and structural strength, is suitable for long-term use under different climatic conditions, ensures that the various parts of the exterior wall 51 can still remain tightly connected under the influence of various environmental factors, and improves the reliability and service life of the system.

[0048] In this embodiment, the assembly and connection method of the exterior wall 51 is further optimized to enhance the modularity and stability of the overall structure. Specifically, the third side wall 513 of the exterior wall 51 is provided with a second dovetail groove 81, and the fourth side wall 514 is provided with a matching second dovetail tenon 82. The shape and dimensions of the second dovetail tenon 82 are precisely designed to securely fit into the second dovetail groove 81, achieving a stable interlocking connection.

[0049] By providing first dovetail tenons 72 and first dovetail slots 71, along with second dovetail tenons 82 and second dovetail slots 81, the modules of exterior wall 51 are securely connected in all directions, improving the structural integrity and effectively enhancing the shear and tensile strength of the connection points. The design of the first and second dovetail connections creates a stable, self-locking connection between the modules of exterior wall 51, reducing displacement and deformation under external forces such as temperature fluctuations, wind pressure, and earthquakes, thereby improving the system's seismic and wind resistance.

[0050] Furthermore, the double dovetail connection facilitates the installation and removal of the exterior wall 51. Repairs or replacements require only the removal of damaged modules, without destroying the entire wall structure. This improves maintenance convenience and cost-effectiveness. This overall design ensures the long-term reliability of the exterior wall 51 in a variety of environmental conditions while maintaining the flexibility of modular assembly.

[0051] In this embodiment, wedges 9 are installed at the ends of the two dovetail joints to enhance the tightness and stability of the connection between the modules of the exterior wall 51. Specifically, wedges 9 are fixedly connected to the outer sides of the first dovetail joint 72 and the second dovetail joint 82. The wedges 9 are designed to interact with the internal structure when inserted into the corresponding first dovetail groove 71 or second dovetail groove 81. In particular, when the wedges 9 are inserted into the corresponding dovetail groove, they gradually dislodge the balls 54 inside the dovetail groove, thereby generating additional fixing force and a self-locking effect.

[0052] Ball bearings 54 are positioned inside the dovetail groove and are subjected to pressure when wedge block 9 is inserted. This pressure pushes the ball bearings 54 away, preventing them from getting stuck in the dovetail joint. Once the dovetail joint is properly positioned, the ball bearings 54 are inserted into holes machined into the dovetail joint surface. This design enhances the locking effect of the dovetail joint and prevents loosening or displacement of the exterior wall 51 due to vibration or external forces.

[0053] The opening function of the wedge block 9 improves the convenience of assembly, ensures the accuracy and firmness of modular splicing, and effectively improves the reliability of the system and the stability of long-term use.

[0054] In this embodiment, to further enhance cooling efficiency, the cooling tubes 43 are designed to be arranged in a serpentine pattern within the frame 2. This serpentine arrangement creates a path with multiple turns within the frame 2, increasing the effective contact area between the cooling tubes 43 and the phase change material 6. This significantly improves the heat exchange efficiency between the cooling tubes 43 and the phase change material 6, allowing the cooling system to more quickly remove heat under high-temperature conditions, maintaining the phase change material 6 within its optimal operating temperature range.

[0055] The serpentine arrangement not only extends the cooling water's flow path within cooling tube 43 but also increases its retention time, ensuring a durable and uniform cooling effect. Furthermore, the serpentine structure evenly covers the interior of frame 2, resulting in a more balanced temperature distribution within frame 2. This effectively avoids localized overheating or overheating, and improves the temperature control accuracy of the building's exterior walls. Furthermore, this serpentine design facilitates the flow of cooling water within cooling tube 43, achieving more efficient heat conduction and adapting to changing ambient temperatures.

[0056] By adopting the design of the serpentine cooling pipe 43, the temperature stability of the inner wall 1 is ensured, while the structural arrangement of the cooling pipe 43 is simplified, thereby improving the heat dissipation efficiency and service life of the entire system.

[0057] The above specific embodiments do not limit the scope of protection of this utility model. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the scope of protection of this utility model.
