Description

Technical Field

[0001] This application relates to the field of aluminum veneers, and particularly to a composite aluminum veneer. Background Art

[0002] As a modern building exterior wall decoration material, aluminum veneers are widely used in high-rise buildings, commercial complexes, public facilities and other fields. With the acceleration of the urbanization process and the progress of technology, aluminum veneers have been widely used in the field of building curtain walls due to their characteristics of light weight, high strength, and easy processing.

[0003] One of the heat insulation and preservation methods of traditional aluminum veneers is to coat a reflective coating on its surface to reflect sunlight. However, the surface of the aluminum veneer also needs to play a decorative role and may not be suitable for coating the reflective coating. Therefore, people in this field have also designed a composite aluminum veneer with a multi-layer structure to weaken the heat transfer between the inner layer and the outer layer through the heat insulation layer in the multi-layer structure, thereby playing a role in heat insulation and preservation. Although this method can play a heat insulation role, it may cause too large a temperature difference between the inner and outer layers of the aluminum veneer, resulting in a relatively large difference in the deformation amounts caused by thermal expansion and contraction between the inner and outer layers, and ultimately causing damage to the structure of the aluminum veneer. Summary of the Invention

[0004] In order to solve the problems of poor heat insulation and preservation effect of aluminum veneers and too large temperature difference between the inner and outer layers, this application provides a composite aluminum veneer.

[0005] The composite aluminum veneer provided by this application adopts the following technical solutions: A composite aluminum veneer includes a connecting rod, a heat insulation block, an air pipe, a first valve, a temperature regulating component, and an outer layer, a heat insulation layer, and an inner layer arranged in sequence; The heat insulation layer is connected to the inner layer; Both the outer layer and the inner layer are provided with cavities inside, and a light-transmitting hole communicating with its interior is provided on one side of the outer layer away from the inner layer; One end of the air pipe is internally communicated with the side surface of the inner layer, and the other end is away from the building wall and in a shaded and cool place; the first valve is arranged on the air pipe; One end of the connecting rod penetrates into the inner layer and is connected to the inner layer, and the other end penetrates through the heat insulation layer and into the outer layer and is connected to the heat insulation block; The connecting rod is provided with air guide holes, a first clamping groove is provided on one side of the inner wall of the outer layer close to the inner layer, the outer layer is slidably connected with the connecting rod, and the outer layer is used to make the heat insulation block be clamped or disengaged from the first clamping groove by sliding; When the heat insulation block disengages from the first clamping groove, the interior of the outer layer is communicated with the interior of the inner layer through the air guide holes; When the heat insulation block is clamped in the first card slot, the heat insulation block blocks the communication between the inside of the outer layer and the inside of the inner layer; The temperature regulating component is arranged inside the inner layer.

[0006] By adopting the above technical solutions, the composite aluminum single board can achieve heat insulation and temperature difference regulation between the inner and outer layers. Specifically: 1. When the heat insulation block is clamped in the first card slot, a gap is formed between the outer layer and the inner layer, avoiding direct heat transfer from the outer layer to the inner layer, and the heat insulation block can prevent heat exchange between the inside of the outer layer and the inside of the inner layer through gas, thereby further improving the heat insulation performance and reducing heat transfer.

[0007] 2. The temperature regulating component is arranged inside the inner layer, so as to ensure that the inner layer and the building wall are at a suitable temperature.

[0008] 3. When it is necessary to reduce the temperature difference between the inner layer and the outer layer, only need to make the heat insulation block disengage from the first card slot, and the inside of the outer layer and the inside of the inner layer are connected through the air guide hole. Since the temperature of the air inside the outer layer is higher than that inside the inner layer due to the outer layer receiving sunlight, the density of the air inside the outer layer is lower and the air pressure is smaller. When the first valve is opened, the cold air in the shaded area enters the inner layer and flows from the inner layer into the outer layer, which is beneficial to cooling the outer layer. During this process, the temperature regulating component can provide cold energy to ensure that the inner layer is always at a suitable temperature, and at the same time can increase the air pressure difference between the inner layer and the outer layer to strengthen the flow effect of the directional air flow.

[0009] Optionally, a second card slot is provided on the side of the inner wall of the outer layer away from the inner layer, and the outer layer has a first state and a second state; In the first state, the heat insulation block is clamped in the first card slot, there is a gap between the outer layer and the heat insulation layer, and the heat insulation block blocks the communication between the inside of the outer layer and the inside of the inner layer; In the second state, the heat insulation block is clamped in the second card slot.

[0010] By adopting the above technical solutions, the fixation of the outer layer and the heat insulation between the inner and outer layers can be realized. Specifically: The heat insulation block is clamped in the first card slot or the second card slot to fix the outer layer.

[0011] When the heat insulation block is clamped in the first card slot, a gap is formed between the outer layer and the heat insulation layer, avoiding heat transfer from the outer layer to the heat insulation layer. And at this time, the heat insulation block effectively blocks the gas flow between the inside of the outer layer and the inside of the inner layer, enhancing the heat insulation effect.

[0012] When the heat insulation block is clamped in the second card slot, the inner layer and the outer layer can be connected through the air guide hole for heat transfer, avoiding too large a temperature difference between the inner layer and the outer layer.

[0013] Optionally, the composite aluminum single plate further includes a sealing block, the sealing block is arranged on a side of the heat insulation block away from the connecting rod, and in the second state, the sealing block seals the light-transmitting hole.

[0014] By adopting the above technical solution, in the second state of the composite aluminum single plate, the sealing block can effectively seal the light-transmitting hole, thereby improving the aesthetic degree of the aluminum single plate.

[0015] Optionally, the outer layer further has a third state, and in the third state, the heat insulation block is located between the first card slot and the second card slot.

[0016] By adopting the above technical solution, when the heat insulation block is located between the first card slot and the second card slot, the outer layer can achieve an intermediate transition state, and this design increases the diversity of working modes of the composite aluminum single plate.

[0017] Optionally, the outer layer includes a first plate body, a second plate body and a support member; The first plate body is arranged on a side of the second plate body away from the inner layer, and the light-transmitting hole is arranged on the first plate body; A groove is arranged on a side of the second plate body facing the first plate body, the groove and the first plate body form an internal cavity of the outer layer, the support member is arranged in the groove and connected to the second plate body, the support member abuts against the first plate body, and the internal cavity of the outer layer is divided into a plurality of reflection cavities, and at least one of the light-transmitting holes communicates with any of the reflection cavities; The cross-sectional size of the reflection cavity is larger than the cross-sectional size of the light-transmitting hole.

[0018] By adopting the above technical solution, the noise reduction ability of the composite aluminum single plate can be effectively improved, and the manufacturing difficulty of the aluminum single plate can be reduced. Specifically: The design of the first plate body and the second plate body makes the preparation of the outer layer simpler.

[0019] The existence of the support member ensures the structural stability of the outer layer, and at the same time divides the cavity into a plurality of reflection cavities. The light entering the reflection cavity can heat the air in the reflection cavity during multiple reflections, prompting the cold air in the inner layer to flow into the outer layer and cool the outer layer. Moreover, the cross-sectional size of the reflection cavity is larger than the cross-sectional size of the light-transmitting hole, so that the sound wave energy entering the reflection cavity can be consumed, playing a certain role in sound absorption and noise reduction.

[0020] Optionally, a reflective layer is arranged on the inner wall of the reflection cavity.

[0021] By adopting the above technical solution, the reflective layer can fully reflect the light entering the reflection cavity, thereby fully heating the air in the reflection cavity during multiple reflections. Moreover, due to the existence of the reflective layer in the structure of the outer layer itself, very little energy of the light entering the reflection cavity is absorbed by the outer layer, avoiding the outer layer from rising in temperature due to absorbing the light energy.

[0022] Optionally, on the side of the inner layer close to the building wall, there are air holes communicating with its interior, and a second valve is provided at the air holes.

[0023] By adopting the above technical solution, when the second valve is opened, the cold air in the inner layer can flow towards the building wall, thereby helping to cool down the building wall.

[0024] Optionally, the temperature adjustment component includes a heating unit and a cooling unit.

[0025] By adopting the above technical solution, the temperature adjustment component includes a heating unit and a cooling unit, enabling the temperature adjustment component to both lower and raise the temperature of the inner layer, thus better adjusting the temperature.

[0026] Optionally, the connecting rod is a heat-insulating rod.

[0027] By adopting the above technical solution, the connecting rod as a heat-insulating rod can effectively reduce the heat transfer between the outer layer and the inner layer, improve the heat insulation performance of the composite aluminum single board, and help maintain the temperature stability indoors.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the connecting rod and the heat-insulating block, and arranging a cavity, light-transmitting holes in the outer layer, a cavity in the inner layer, and an air pipe communicating with the inner layer, the state of the outer layer is switched. By switching different states, the heat insulation performance of the composite aluminum single board can be improved or the temperature difference between the inner layer and the outer layer can be reduced; 2. The design of the first plate body, the second plate body, and the support member of the outer layer enables multiple reflection cavities to be formed inside. A reflective layer is provided in the reflection cavity, so that the heat of the sunlight entering the reflection cavity is absorbed by the air in the reflection cavity as much as possible. While forming a directional cold air flow flowing from the inner layer to the outer layer, the sunlight entering the reflection cavity will not cause the temperature of the outer layer to rise, helping to reduce the temperature of the outer layer.

[0033] The following further elaborates on this application in conjunction with the attached Figures 1 to 3 drawings.

[0034] As Figures 1 to 3 shown, an embodiment of this application discloses a composite aluminum single board, which includes a connecting rod 1, a heat insulation block 2, a sealing block 3, an air pipe 4, a first valve 41, a second valve 5, a temperature regulating component 6, and an outer layer 7, a heat insulation layer 8, and an inner layer 9 arranged in sequence.

[0035] Specifically, the composite aluminum single board is used for installation on a building wall. Among them, the outer layer 7 is on the side away from the building wall, and the inner layer 9 is on the side close to the building wall. The inner layer 9 is connected to the building wall through connection structures such as keels.

[0036] Both the inner layer 9 and the outer layer 7 are made of aluminum alloy material, and cavities are provided inside both of them, which helps to reduce the material usage.

[0037] Among them, the heat insulation layer 8 is attached to and connected to the inner layer 9, thereby preventing heat transfer between the outer layer 7 and the inner layer 9 through contact. The heat insulation layer 8 can adopt materials with low thermal conductivity such as vacuum insulation panels, calcium silicate boards, or phenolic resin boards.

[0038] The temperature regulating component 6 is arranged inside the inner layer 9. The temperature regulating component 6 includes a heating unit and a cooling unit. The heating unit can be components such as heating wires. The cooling unit can be a thermoelectric cooler and a conventional water cooling device.

[0039] One end of the air pipe 4 is communicated with the inside of the side surface of the inner layer 9, and the other end is away from the building wall and is in a shaded and cool place or other relatively cool areas. The air pipe 4 is wrapped with heat insulation cotton, and the first valve 41 is arranged on the air pipe 4. An air hole communicated with its inside is opened on the side of the inner layer 9 close to the building wall, and the second valve 5 is arranged at the air hole.

[0040] The outer layer 7 includes a first plate body 71, a second plate body 72 and a support member 73. The first plate body 71 is disposed on the side of the second plate body 72 away from the inner layer 9 and is detachably connected to the second plate body 72. A light-transmitting hole 711 is provided on the first plate body 71.

[0041] A groove is provided on the side of the second plate body 72 facing the first plate body 71. The groove and the first plate body 71 form the inner cavity of the outer layer 7. The support member 73 is disposed in the groove and connected to the second plate body 72. The support member 73 abuts against the first plate body 71, thereby preventing the first plate body 71 from being recessed and deformed. The support member 73 divides the inner cavity of the outer layer 7 into a plurality of reflection cavities 74, and at least one light-transmitting hole 711 communicates with any reflection cavity 74.

[0042] Wherein, the cross-sectional dimension of the reflection cavity 74 is larger than the cross-sectional dimension of the light-transmitting hole 711. After external noise enters the reflection cavity 74 through the light-transmitting hole 711, the sound wave energy can be gradually consumed, thereby playing a role in sound absorption and noise reduction.

[0043] In addition, when a heat source such as sunlight irradiates on the outer layer 7, part of the sunlight can enter the reflection cavity 74 through the light-transmitting hole 711. Through multiple reflections of the sunlight by the reflection cavity 74, the heat of the sunlight entering the reflection cavity 74 is absorbed by the air in the reflection cavity 74. Wherein, a reflective layer is provided on the inner wall of the reflection cavity 74, and the reflective layer can be a reflective coating or a light-colored smooth surface. The reflective layer can fully reflect sunlight, so that the heat of sunlight is absorbed by the air in the reflection cavity 74 as much as possible and not absorbed by the outer layer 7 structure itself. Although the outer layer 7 structure itself will still absorb part of the heat, since even if the light-transmitting hole 711 is not provided, the sunlight entering the reflection cavity 74 should originally irradiate on the outer layer 7 structure itself. Therefore, opening the reflection cavity 74 and the light-transmitting hole 711 and introducing the sunlight that should originally irradiate on the outer layer 7 structure itself into the reflection cavity 74 will not cause the outer layer 7 to absorb more heat.

[0044] Since the light-transmitting hole 711 needs to allow sunlight and sound waves to enter the reflection cavity 74, based on the different functions of the light-transmitting hole 711, there may be differences in the size requirements for the light-transmitting hole 711. A single-size light-transmitting hole 711 may not be able to effectively reflect each function. Therefore, light-transmitting holes 711 with different sizes can be set according to actual needs.

[0045] As Figures 1 to 3 shown, the connecting rod 1 penetrates through the heat insulation layer 8, and one end of the connecting rod 1 penetrates into the inner layer 9 and is connected to the inner layer 9, and the other end penetrates into the outer layer 7 and is connected to the heat insulation block 2 in the reflection cavity 74. The connecting rod 1 is a heat insulation rod, thereby avoiding heat transfer between the inner layer 9 and the outer layer 7 through the connecting rod 1. For example, the connecting rod 1 can be made of a material with good heat insulation performance such as plastic or phenolic resin.

[0046] The sealing block 3 is arranged on the side of the heat insulation block 2 away from the connecting rod 1. On the inner wall of the reflection cavity 74, a first card slot 741 is arranged on the side close to the inner layer 9, and a second card slot 742 is arranged on the side away from the inner layer 9. An air guide hole 11 is arranged on the connecting rod 1. The outer layer 7 can slide relative to the connecting rod 1, so as to switch between the first state, the second state and the third state.

[0047] As Figure 1 shown, in the first state, the heat insulation block 2 is clamped in the first card slot 741, so as to fix the outer layer 7. And at this time, there is a gap between the outer layer 7 and the heat insulation layer 8, avoiding the contact between the outer layer 7 and the heat insulation layer 8 to further prevent heat transfer. At this time, the heat insulation block 2 blocks the connection between the inside of the outer layer 7 and the inside of the inner layer 9 through the air guide hole 11, so as to effectively avoid heat exchange between the outer layer 7 and the inner layer 9, and the heat preservation and insulation performance is better. It is not necessary to turn on the temperature adjustment component 6 to make the inner layer 9 within a suitable temperature range.

[0048] As Figure 2 shown, in the second state, the heat insulation block 2 is clamped in the second card slot 742. At this time, a part of the connecting rod 1 is located in the reflection cavity 74, and the inside of the inner layer 9 is communicated with the reflection cavity 74 through the air guide hole 11 on the connecting rod 1. The gas can flow between the inner layer 9 and the outer layer 7 through the air guide hole 11, so as to realize heat transfer between the inner layer 9 and the outer layer 7 and reduce the temperature difference between the inner layer 9 and the outer layer 7.

[0049] For example, in low-temperature weather such as winter, after the outer layer 7 receives the sunlight heat, it can help heat the inner layer 9 through air circulation, avoiding the temperature of the inner layer 9 being too low.

[0050] For another example, under extreme conditions such as summer and winter, both the aluminum single plate and the building wall may be damaged in structure under extreme temperatures, and the temperature inside the building is also likely to be too high or too low. At this time, the temperature of the inner layer 9 and the building wall can be improved through the temperature adjustment component 6. And in the second state, the heat or cold of the inner layer 9 can be transferred to the outer layer 7, and then the temperature of the outer layer 7 can be improved, avoiding situations such as scalding or freezing hands when people touch the outer layer 7.

[0051] In the second state, the second valve 5 can be opened, so that the hot air or cold air in the inner layer 9 flows to the building wall, so as to better improve the temperature of the building wall.

[0052] In the second state, the outer layer 7 can be attached to the heat insulation layer 8 to make the structure of the outer layer 7 more stable. Of course, the outer layer 7 can also not be in contact with the heat insulation layer 8 to ensure improved heat insulation performance in a high-temperature environment.

[0053] Furthermore, the shape of the sealing block 3 is adapted to the light-transmitting hole 711. In the second state, the sealing block 3 can block the light-transmitting hole 711. Moreover, the material and surface pattern of the sealing block 3 are adapted to the material and surface pattern of the first plate body 71. When the sealing block 3 blocks the light-transmitting hole 711, the side of the sealing block 3 away from the inner layer 9 is flush with the side of the first plate body 71 away from the inner layer 9, thereby improving the aesthetics of the outer layer 7. Secondly, by blocking the light-transmitting hole 711, it is possible to prevent the reflection cavity 74 from communicating with the outside through the light-transmitting hole 711. When the temperature is adjusted by the temperature adjustment component 6, the loss of heat or cold can be reduced.

[0054] As Figure 3 shown, in the third state, the heat insulation block 2 is located between the first card slot 741 and the second card slot 742. The reflection cavity 74 and the inside of the inner layer 9 are still connected through the air guide hole 11, and under the condition of light, sunlight can enter the reflection cavity 74 through the light-transmitting hole 711. Since the air in the reflection cavity 74 is close to the outside and is heated by the sunlight entering the reflection cavity 74, the temperature of the air in the reflection cavity 74 is higher than the temperature inside the inner layer 9. Since the higher the temperature of the air, the lower the density, a pressure difference will be formed between the inside of the inner layer 9 and the reflection cavity 74. As a result, when the first valve 41 is opened, the cold air in the shaded area will flow into the inner layer 9 and then flow from the inner layer 9 into the reflection cavity 74. The cold air contacts the outer layer 7, thereby neutralizing the temperature of the outer layer 7 and reducing the temperature difference between the outer layer 7 and the inner layer 9.

[0055] During this process, although part of the heat in the reflection cavity 74 also enters the inner layer 9 through heat transfer of the air, since the air flow direction is mainly from the inner layer 9 to the outer layer 7, the temperature of the inner layer 9 will not rise significantly during this process. When it is necessary to reduce the temperature of the outer layer 7, by switching the outer layer 7 to the third state, the temperature difference between the inner layer 9 and the outer layer 7 can be reduced. Even if the temperature adjustment component 6 is not started, the cold air in the shaded area or other cool areas can still enter the inside of the inner layer 9 through the air pipe 4 and form a directional air flow from the inner layer 9 to the outer layer 7 to help cool the outer layer 7. Of course, using the temperature adjustment component 6 for refrigeration can supplement the cold quantity, ensuring that the inner layer 9 is always within a suitable temperature range and improving the stability of the directional air flow.

[0056] In addition, in the third state, the second valve 5 is in a closed state to avoid affecting the formation and stability of the directional air flow.
