SMART SANDWICH PANEL WALL

Abstract

The invention relates to a structural element with an internal mechanism for thermal insulation, suitable for use in living spaces such as prefabricated houses, caravans, and tiny houses. Louvered slats, positioned between the outer surface panels of a sandwich panel wall, are arranged to increase thermal resistance in the gap depending on the temperature difference between the interior and exterior, thus providing insulation. The movement required to position the louvered slats correctly is achieved by a processor that senses the interior and exterior temperatures and sends a signal to a small DC motor, thereby activating the motor.

Description

1 TARIFF SMART SANDWICH PANEL WALL TECHNICAL FIELD The invention is suitable for living spaces such as prefabricated houses, caravans, and tiny houses. It relates to a building element that has an internal mechanism for thermal insulation purposes. The shutter panels, located between the exterior surface panels of the sandwich panel wall, are for both interior and exterior use. to increase the thermal resistance in the cavity depending on the ambient temperature difference Insulation is provided by positioning the shutter blades in the correct position. The movement required for its positioning is a 10 that senses the indoor and outdoor temperatures. The processor sends a signal to a small DC motor, thus starting the motor. It is accomplished through skill. PREVIOUS TECHNIQUE In general, wall building elements should be resistant to heat transfer, i.e., heat 15 Good insulation properties are desired. Efforts in this area are directed towards materials such as bricks and blocks. for relatively small structural elements as well as sandwich panel walls These efforts to increase thermal resistance are ongoing. Common practices in these endeavors include: filling the voids with porous material with a low heat conductivity coefficient and the air in the void 20 as studies on creating spatial geometry in a way that minimizes movement They can be classified. In both applications, heat is reduced in buildings by increasing thermal resistance. It is possible to reduce losses / gains. The production cost of the former is relatively low. The first is more commonly implemented. The second involves creating new patterns and standards. Because it may be necessary, its transformation into a product remains limited. On the other hand, sometimes Depending on the type of void foreseen, for example, in winter conditions when the outside environment is cold, 25 The geometry that contributes to insulation enhances heat transfer in hot outdoor conditions. This can lead to the opposite result of what was desired. Therefore, wall construction... In most cases, the recommended arrangements for insulating the internal cavities of the elements are for each It does not provide any benefit in terms of climate or season. The fact that interior space arrangements do not always provide benefit, building wall 30 leading the way in cavity design studies aimed at increasing thermal resistance in components It is a problem that needs to be overcome. Numerous studies deal with heat transfer by natural convection in enclosed spaces. A study that served as a source for this work was carried out by Davis (1983). 2 Davis's article is about natural transport within a square-shaped enclosed environment. This study serves as a source for verification purposes in research in this field to date. It was used as an article. In later studies, it was kept closed. thermal boundary conditions in the walls surrounding the environment, as well as the geometric shapes of these walls The effect of its positioning on heat transfer has also attracted the attention of researchers. 5 Studies on this subject include Moukalled & Acharya (1997) and Moukalled & Darwish The articles of (2007) can be given as an example. These researchers were the first in the literature to discuss closed In heat transfer by natural convection in different environments, the walls surrounding the environment are different the effect of its positioning is described as "buoyancy-inducing". and they have described it as "buoyancy-opposing". 10 Natural transport occurs when a heated layer of fluid (air) expands and becomes lighter. by rising and the relatively cold layer being replaced by the rising fluid It is a phenomenon that occurs. Therefore, this movement is in the vertical direction (gravity). (in the direction) it occurs. Thus, the fluid motion in the vertical direction Barrier walls prevent natural transport, while redirecting walls allow natural transport to continue. They serve the function of supporting transportation. Moukalled & Acharya and Moukalled & Darwish's The classifications they made in their studies are as follows (Figures 1-2) It is explained. In the following years, two different studies were carried out by Al-Hazmy (Al- Hazmy (2006) and Al-Hazmy (2010)) in the first case, the void in a hollow brick is more than 20 dividing into square voids, with single and multiple voids having different insulation materials. The effect of different filling conditions on thermal resistance was investigated. In the second case, again... The square voids in the brick are divided by angled dividers to create triangular voids. Numerical thermal analysis was performed in this way. By Arıcı and Kan (2018) In the numerical study conducted, as seen in Figure 3, the vertical edges are affected by gravity. The thermal resistance of a square cavity coinciding with the direction of rotation being rotated 45°. Its effect on it has been investigated. This structure simultaneously supports the buoyant force and It includes edges that resist the buoyant force. However, in terms of thermal resistance, it is not sloped. Increases ranging from 11% to 15% depending on the temperature difference relative to the square gap. It has been observed. 30 On the other hand, patent databases contain products related to sandwich panel walls. These databases contain terms such as "smart sandwich wall". “temperature sensitive wall”, “inclined partition wall” Searches using keywords / keyword phrases similar to "internal partitioned wall") 3 Numerous discoveries related to this subject have been made. Some of these are; Morrison (1977), Akira (1996), Massimo (2010), Willson (2012), Bo Serrin (2012) and Youhua (2023) These are inventions made by [name of person / organization]. In Morrison's invention, the sandwich cavity consists of successive triangles and hexagons. a relatively lightweight material composed of voids and claimed to have high mechanical properties. A product is offered. A claim regarding the thermal insulation of the offered product is made. It is not available. Akira's invention uses an inner and outer surface to increase the thermal efficiency of the panel wall. by using a heat pipe operating between the surfaces, more efficient utilization of the incoming radiation. A product is recommended for this purpose. 10 Massimo's invention consisted of a layered wall made up of oval sub-compartments. One product is recommended. Willson's invention involves reflective surfaces combined with an insulating layer. It proposes a product consisting of layers that contain voids. In Bo Serrin's invention, the surfaces facing the interior and exterior environments reflect the climate of these environments. panels designed according to the conditions and an insulation layer between these panels A panel wall consisting of these panels is proposed. Youhua's invention utilizes the temperature difference between the interior and exterior environments to create a wall. by storing heat in the wall through the evaporation of condensed water A product that enhances performance is recommended. 20 THE PURPOSE OF THE INVENTION In this invention, unlike the known state of the art, the space between sandwich panels... The gap is heated with the help of automation, depending on the temperature difference between the surfaces. There are adjustable sloping interior compartments that reduce airflow. Thus, the cold outside 25 Under ambient conditions, from the inner surface to the outer surface, and under hot outdoor conditions, from the outer surface. Heat transfer from the surface to the interior decreases, meaning the wall is warm both in summer and winter. It functions equally well in both day and night conditions. LIST OF FIGURES 30 Figure 1. Geometry resisting buoyancy. Figure 2. Geometry supporting the buoyant force. Figure 3a. Natural transport in a square space. Figure 3b. Natural transport in a rotated square space. 4 Figures 4-5-6 illustrate the results of the invention. A square space is provided for comparison purposes. Isothermal curves and streamlines are shown for this purpose. The numerical analysis findings presented in Figure 4 show that the left surface is hot and the right surface is cold. (a) isotherms and (b) in a square enclosed space with insulated horizontal surfaces. Streamlines are observed. The consistency of these results with the relevant literature has been confirmed. 5 The verification test uses the Nu number (Nusselt number), a dimensionless number for heat transfer. This was done in terms of and the difference between this and Davis' (1983) result is 3.1%. Numerical analysis of the relationship between buoyant forces and viscous forces in natural transport. The test was performed for a value of 10,000 for the Ra (Rayleigh) number, which represents the ratio. The lower and upper quadrants of a rectangular space whose vertical side is twice the length of its horizontal side are 10 for the case where the solid is accepted and the square space between them is the solution area This has been accomplished. Therefore, the vertical parallel lines seen in the isotherm graph are not directly related to the isotherm graph. The lines indicate that the region is isolated, and the lineless area seen in the streamline graph is the same. The diagram shows an insulating solid, meaning a region where natural transport cannot occur. Figures 5 and 6 respectively show the objects resisting and supporting the buoyant force. Results for enclosed environments with inclined surfaces supporting the force. It is seen. In the counter-lift arrangement given in Figures 5a and 5b, the left A parallelogram enclosed structure with a hot surface, a cold surface, and insulated sloping surfaces. The medium has the same volume as the square medium in Figure 4, but with 1.2145 times more friction. It has a surface area (wall area). The test also shows that the Ra number is 104 for this geometry. This has been achieved. A decrease in the dimensionless heat transfer coefficient compared to that in a square environment. Thus, the increase in thermal resistance is 61.9%. This increase in thermal resistance is due to friction. in response to a 17.66% increase in surface area (expressed as a percentage of 1.2145 times) is provided. The remaining 44.24% difference is due to regulation 25, which counteracts the buoyancy force. This stems from its effect on natural transport. In the buoyancy support arrangement given in Figures 6a and 6b, the left This parallelogram is enclosed, with one side cold, the other side warm, and the sloping sides insulated. The environment is the same as in Figure 5, but the thermal boundary conditions have been reversed. The results here are also... This was performed for a Ra number value of 104. The reduction in thermal resistance (insulation 30) (deterioration in ability), 96% according to the regulation that counteracts buoyancy, This is 162% compared to the standard square gap situation.

It consists of the hot surface (front frame) (1) shown in Figure 7, and the cold surface (1) shown in Figure 8. surface (rear frame) (2), quarter discs (6) side wing holder side in Figure 12 Assembly of the frame (3) and the wing holder side frame (4) in Figure 10 15 It consists of a chassis (5) (Figure 11). After the chassis (5) is formed, it is made with quarter discs (6) Each of the assembled shutter wings (15) (Figure 12) will be inclined at 45° Using the pin on the left in the figure, the wing holders (5) of the chassis are attached separately. It is passed through. The processor (7) is also placed in the uppermost wing holder gap, and the drive disc is placed on its spindle. 20 mounted drive motor (8) and mechanism plate (9) on which these two elements are mounted The internal mechanism is completed by installing the resulting drive mechanism (Figure 16). (Figure 17). Two rack gears (16) are fitted into the channel (10, 11) respectively. on the inner surface of the front panel plate (12) and the rear panel plate (13), on the drive disc side It is assembled in such a way that the panel on which rack gears (16) are mounted. The panel plate section of the invention was formed with plates (12, 13) (Figure 22 and Figure 23). The panel boards (12, 13) are screwed to the chassis (5) to form the smart sandwich wall. is being completed (Figure 24). Detailed descriptions of the elements of the invention are given below. Hot surface (Front frame) (1): 30 Metal-based profile (low-density alloy) It is a manufactured frame. Cold surface (Rear frame) (2): It is the same as the front frame. Wing holder side frame for quarter discs (3): Front and rear frame (1, 2) It is manufactured from the same material as the material. The shutter wings (15) and the mechanism 7 For the placement of the plate (9), the vertical columns of the frame are made of the same material and are equal. They are combined with spaced shelving units. Wing holder side frame (4): Wing holder side frame for quarter discs (6) side (3) is the same. Quarter disc mounted shutter blade(s) (15): 5 of the shutter blades (15) in the invention its importance depends on the temperature difference between the case surfaces (panel sheets (12, 13)) The ability to create high thermal resistance within the void under all conditions by changing their slopes. Their durability is key. They can be made of solid wood slats or plastic. Quarter discs (6) to be mounted on the shutter wings (15) are made of rack and pinion gear (16) They converted the translational motion they received into rotational motion in accordance with the purpose of the invention. They transform the wings to ensure proper positioning. They are metal or plastic based. They can be. Each panel wall can have a different number. For example, panel boards. For a 2 m high panel wall with a 4 cm gap between (12, 13), these 50 pieces A quarter disc (6) mounted shutter sash (15) is required. The processor (6) is correct 15 depending on the direction of the temperature difference between the plates (12, 13). It operates the drive motor (8). Drive motor (8): A direct current motor which is the source of movement of the movable shutter wings (15). It is the motor. The drive disc (quarter mounted on the shutter blades (15)) is attached to the end of its shaft. The discs (6) are identical and mounted. It is powered by battery or rechargeable battery. Mechanism plate (9): The processor (7) and drive motor (8) are mounted on it and 20 It is manufactured from the same material as the shutter sash (15). However, it is more than the shutter sash (15). narrow (the distance between panel plates (12, 13)). Front panel plate rack gear (16) and channel (10): Drive quarter disc (14) converting rotational motion into translational motion and simultaneously converting translational motion It is the gear that transmits the rotational movement of the shutter blade (15) to the quarter discs (6). 25 The gear moves through the channel into which it passes. The gear and channel (10) are made of metal or It can be plastic-based. Rack and pinion gear (16) and channel (11) for the rear panel plate: Rack and pinion gear for the front panel plate It is the same gear. These gears drive alternately and in opposite directions, each time in a quarter-speed. The disk (14) is shifted by p and pro / 2. 30 Front panel plate (12): This is the plate required to cover the front face of the panel wall. It is made from composite wood-based material. Rear panel plate (13): It is the same as the front panel plate (12) and covers the rear surface of the panel wall. It is the sign needed to close it. 8 Figure 26 shows the movement stages of the movable shutter wings (15). Each shutter blade (15) is connected from its central axis to the center of its quarter disc (6). The translational motion from the Krameyer gear (16) rotates the quarter discs (6) and Therefore, the direction of the wings attached to the discs (6) changes. This event is shown in the figure. As seen, it is completed in stage IV. In stage V, the initial stage is 5. (Stage I) is being revisited. The sandwich wall is shown in the figure for the position in Stage I. If we assume that the surface on the right is warm and the surface on the left is cold; then the shutter The inclined gaps formed by the wings (15) have the function of supporting the lift force. This will mean that natural transport will increase. Temperatures on hot and cold surfaces will rise. The processor (7) that will read this reading interprets this reading as a decrease in thermal resistance. and by sending a signal to the drive motor (8) to the lifting force of the shutter wings (15) The stages of transitioning to a position of resistance are beginning. Each of these four stages of the process... During this stage, the drive disc rotates clockwise by p degrees (180°). The stages are as follows: is happening: In the first stage, as the drive disc rotates by a distance p, the 15 on the right, i.e., the hot surface side... Rack and pinion gear (16) pro / 2 (RO drive quarter disc / shutter quarter disc radius) will be shifted. During this time, the sequential shutter quarter discs (6) will rotate by p at intervals of one each. The attached wings will put the device in a position to counteract the lift force. In the second stage, the drive disc rotates again by p units, this time on the left, i.e., the cold surface. The rack gear (16) on the side is similarly shifted and 20 on the remaining wings It is positioned to counteract the buoyant force. Thus, the sandwich wall interior The partitions are made of high thermal resistance walls. In stage III, the conditions are that the left surface of the wall is warm and the right surface is cold. The formation of voids with inclined surfaces (day / night, summer / winter) provides buoyancy. acquiring supporting qualities and processor (7) drive motor (8) again 25 It operates. This time, the drive disc moves counterclockwise by a distance p. In stage IV, the movement, which starts in the counterclockwise direction, causes the drive disc to rotate again by p. By rotating, it reaches position V, which is equivalent to position I, creating a porous structure with high thermal resistance. This has happened. Thus, the drive motor (8) drives the drive disk, each of the processor (7) Turn the shutter wings (15) clockwise / counterclockwise by 2p at the mark thermal 30 It is positioned in a way that will create high resistance.
