Description

Technical Field

[0001] This application relates to the photovoltaic field, and in particular to an isolation device for photovoltaic modules. Background Technology

[0002] In related technologies, during the production of photovoltaic modules, after the lamination process, the temperature of the perovskite cell module rises, requiring cooling. Using air cooling or water cooling methods can affect the stability of the perovskite cell layer and impact mass production. Instead, natural cooling is achieved through contact with an isolation device. However, when the freshly produced, high-temperature perovskite modules come into direct contact with the isolation device, the high module temperature makes them prone to adhesion. This adhesion significantly increases the risk of module breakage during subsequent loading and unloading, damaging the modules, affecting production efficiency, increasing production costs, and hindering the smooth mass production of perovskite solar modules. Therefore, improving the anti-adhesion properties between photovoltaic modules and the isolation device is the technical problem this application aims to solve. Utility Model Content

[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] The following is for reference. Figures 1-7 This application describes an isolation device 100 for a photovoltaic module 8 according to an embodiment of the present application.

[0036] An isolation device 100 for a photovoltaic module 8 according to an embodiment of this application includes: a first isolation body 1 and a second isolation body 2. The first isolation body 1 extends in a first direction, and a first contact surface 11 is formed on both the top and bottom surfaces of the first isolation body 1. The second isolation body 2 is disposed on the outer periphery of the first isolation body 1 and extends along a second direction. The angle between the second direction and the first direction is α, where α satisfies: 0°<α≤90°. A second contact surface 21 is formed on both the top and bottom surfaces of the second isolation body 2. A protrusion 3 and / or a recess 4 are formed on at least one of the first contact surface 11 and the second contact surface 21. The protrusion 3 is adapted to contact the photovoltaic module 8, and the recess 4 is adapted to form a gap space with the photovoltaic module 8.

[0037] In related technologies, during the production of photovoltaic module 8, after the lamination process, the temperature of the perovskite cell module rises, requiring cooling. Using air cooling or water cooling methods would affect the stability of the perovskite cell layer and impact mass production. Instead, natural cooling is achieved through contact with the isolation device 100. When the freshly produced, high-temperature perovskite module comes into direct contact with the isolation device 100, the high module temperature makes it prone to adhesion. This adhesion significantly increases the risk of breakage during subsequent loading and unloading, not only damaging the module but also affecting production efficiency, increasing production costs, and hindering the smooth mass production of perovskite solar modules.

[0038] In the isolation device 100 for photovoltaic module 8, the first isolation body 1 extends in a first direction, and its top and bottom surfaces have first contact surfaces 11. The second isolation body 2 is disposed on the outer periphery of the first isolation body 1 and extends in a second direction at a certain angle to the first direction, and its top and bottom surfaces have second contact surfaces 21, wherein the angle is α, and α satisfies: 0°<α≤90°. Since there is an angle between the extension directions of the second isolation body 2 and the first isolation body 1, the first isolation body 1 extends along the first direction, while the second isolation body 2 extends in a direction at an angle α to the first direction. The second isolation body 2 no longer supports the first isolation body 1 in the same angular dimension, but forms support points at multiple angular positions, which can more evenly distribute the weight of the photovoltaic module 8, reduce local pressure, and use a smaller contact area to support the weight of the photovoltaic module 8.

[0039] A protrusion 3 and a recess 4 are formed on at least one of the first contact surface 11 and the second contact surface 21, or a protrusion 3 is formed on at least one of the first contact surface 11 and the second contact surface 21, or a recess 4 is formed on at least one of the first contact surface 11 and the second contact surface 21. When the high-temperature photovoltaic module 8 comes into contact with the isolation device 100, the area of ​​the protrusion 3 is significantly reduced compared to the contact area of ​​the planar surface due to the presence of the protrusion 3 on the contact surface. When there is a recess 4 on the contact surface, the recess 4 will form a gap space with the photovoltaic module 8. This gap space allows air to circulate, heats the photovoltaic module 8 more quickly, and reduces the risk of adhesion. At the same time, when the module comes into contact with the isolation device 100, the gap space prevents the two from directly adhering to each other over a large area, further reducing the probability of adhesion. Therefore, by setting the protrusion 3 and the recess 4 on the first contact surface 11 and the second contact surface 21, and combining the angle between the extension direction of the second isolation body 2 and the first isolation body 1, the contact area between the first isolation body 1 and the second isolation body 2 and the photovoltaic module 8 can be reduced, which can further improve the anti-adhesion between the photovoltaic module 8 and the isolation device 100, avoid adhesion between the photovoltaic module 8 and the isolation device 100, increase the risk of breakage of the photovoltaic module 8, and improve the production efficiency of the photovoltaic module 8.

[0040] According to some embodiments of this application, the isolation device 100 for photovoltaic module 8 is configured as a plurality of second isolation bodies 2 and spaced apart on the outer periphery of the first isolation body 1.

[0041] Multiple second isolation bodies 2 are spaced apart, forming multiple gaps between them. These gaps provide channels for air circulation. When the high-temperature photovoltaic module 8 is placed on the isolation device 100 and needs to dissipate heat, hot air can flow upward through these gaps, while cold air can be supplied from below, forming natural convection. According to the principle of heat transfer, hot air with lower density rises and cold air with higher density falls. Such natural convection can accelerate heat exchange, allowing the photovoltaic module 8 to cool down more quickly. The contact area between each second isolation body 2 and the photovoltaic module 8 is relatively small. Compared with the large-area contact of continuously arranged second isolation bodies 2, the overall contact area is significantly reduced. The smaller the contact area, the lower the possibility of adhesion caused by intermolecular forces. When the photovoltaic module 8 is at a high temperature after the lamination process and comes into contact with the isolation device 100, the smaller contact area makes it less likely for the module to stick to the isolation device 100, thereby reducing the risk of module breakage due to adhesion during subsequent loading and unloading, improving production efficiency, and reducing production costs.

[0042] According to some embodiments of this application, an isolation device 100 for a photovoltaic module 8 has a plurality of spaced first processing areas formed on a first contact surface 11 and / or a second contact surface 21, and each first processing area has a protrusion 3 and / or a recess 4 formed therein.

[0043] The multiple spaced first processing areas mean that at least one of the first contact surface 11 and the second contact surface 21 has multiple independent areas with protrusions 3 and / or recesses 4. This can be understood as multiple independent areas having protrusions 3, or multiple independent areas having recesses 4, or multiple independent areas having both protrusions 3 and recesses 4 on at least one of the first contact surface 11 and the second contact surface 21. When the photovoltaic module 8 contacts the isolation device 100, large... Planar contact with a large area is prone to adhesion due to intermolecular forces. However, the spacing of the first treatment area divides the potentially large-area adhesion into multiple small contact areas. When the protrusion 3 in each first treatment area contacts the photovoltaic module 8, the contact area is only the top area of ​​the protrusion 3, which is significantly reduced compared to planar contact. The multiple spaced first treatment areas make the total actual contact area much smaller than the planar contact area without treatment areas. Furthermore, the spacing allows air to enter the gaps between the treatment areas more easily, further hindering the effective action of intermolecular forces, thereby greatly reducing the possibility of adhesion.

[0044] The gaps between the first processing zones, which are spaced apart, create more channels for air circulation. When the photovoltaic module 8 reaches a high temperature after the lamination process and needs to dissipate heat, the hot air will rise due to the density difference. These gaps make it easier for the hot air to rise and escape, and allow cool air to enter more smoothly from below to replenish it. Compared with the case without spaced processing zones, this increases the contact area and contact path between the air and the module surface. From the perspective of heat transfer, more airflow can accelerate heat exchange and improve heat dissipation efficiency.

[0045] According to some embodiments of this application, an isolation device 100 for a photovoltaic module 8 is provided in each first processing area with a plurality of protrusions 3 and / or recesses 4 spaced apart. The protrusions 3 are constructed in at least one of the form of strips or raised dots, and the recesses 4 are constructed in at least one of the form of grooves or holes.

[0046] The multiple spaced protrusions 3 and concave portions 4 significantly reduce the actual contact area with the photovoltaic module 8. Taking the dotted protrusion 3 as an example, its contact with the module is only a series of tiny points. Compared with planar contact, the contact area is greatly reduced. The smaller the contact area, the less likely the intermolecular forces are to exert their influence over a large area, thus significantly reducing the possibility of adhesion. The grooved or perforated concave portions 4 form a space between the module and the module, which can be filled with air, further hindering the molecules between the module and the isolation device 100 from getting close to each other, thus cutting off the physical conditions for adhesion. Moreover, the spaced protrusions 3 and concave portions 4 disperse the contact area between the module and the isolation device 100. Even if slight adhesion occurs in some local areas due to special circumstances, since other areas are independent, it will not cause the entire module to adhere to the isolation device 100 over a large area. This reduces the risk of module breakage due to adhesion during subsequent loading and unloading, and improves production stability and product yield.

[0047] Among them, such as Figure 2 The diagram shows a schematic of the isolation device 100 with a perforated recess 4.

[0048] like Figure 3 The diagram shows a schematic of the structure of the isolation device 100 with the heat-insulating tape protrusion 3.

[0049] like Figure 4 The diagram shows a schematic of the isolation device 100 with a groove-shaped recess 4.

[0050] like Figure 5 The diagram shows a schematic of the isolation device 100 with protrusions 3.

[0051] According to some embodiments of this application, the isolation device 100 for photovoltaic module 8 has a protrusion 3 and / or a recess 4 constructed as strips with the angle between the extending direction and the first direction being β, and β satisfies: 0°≤β≤90°.

[0052] The strip-shaped protrusions 3 and concave portions 4 at different angles affect the airflow path between the photovoltaic module 8 and the isolation device 100. When β = 0°, the air can flow relatively smoothly along the extension direction of the strip structure, forming a stable airflow channel along the length of the module, which is beneficial for heat conduction and convection heat dissipation. As the β angle increases, the airflow path becomes longer. When β = 45°, the air will collide with and turn multiple times with the strip structure during the flow, increasing the contact opportunities between the air and the module surface, thereby improving the heat exchange efficiency. At the same time, the presence of the concave portion 4 also provides more storage and flow space for the air, further promoting air convection. This airflow path can accelerate the exhaust of hot air and the replenishment of cold air, enabling the photovoltaic module 8 to cool down faster after lamination, maintaining its performance stability, and preventing damage to the materials and structure of the photovoltaic module 8 due to high temperature.

[0053] According to some embodiments of this application, the isolation device 100 for a photovoltaic module 8 has a protrusion 3 constructed as heat-insulating tape and wrapped around at least a portion of the first isolation body 1; or, the protrusion 3 is constructed as a strip-shaped protrusion structure integrally disposed with the isolation device 100.

[0054] When heat-insulating tape is used as the protrusion 3, the surface properties of the heat-insulating tape typically provide a certain degree of anti-adhesion capability. When the high-temperature photovoltaic module 8 comes into contact with the first insulating body 1 wrapped with heat-insulating tape, the special material on the surface of the tape can reduce the intermolecular forces between the tape and the photovoltaic module 8, thereby reducing the possibility of adhesion. Since the tape is wound, the contact with the photovoltaic module 8 is intermittent, further reducing the contact area and making adhesion even more difficult to occur. During subsequent loading and unloading processes, the risk of photovoltaic module 8 breakage due to adhesion is also reduced, improving product yield and production efficiency. The heat-insulating tape is made of Teflon.

[0055] When the strip-shaped protrusion structure is integrally formed with the isolation device 100 as the protrusion 3, the integrally formed structure gives the entire isolation device 100 high structural strength and stability. During the process of supporting the photovoltaic module 8, the strip-shaped protrusion structure can withstand greater pressure without easily deforming or being damaged. From a mechanical point of view, the integral structure avoids the support failure problem caused by loosening or breaking of the connection parts, and can more reliably support the photovoltaic module 8. When placing a heavy photovoltaic module 8, the strip-shaped protrusion structure can evenly distribute the weight of the module, preventing excessive local pressure from damaging the isolation device 100, while also ensuring the stability of the photovoltaic module 8 and reducing its shaking or displacement during placement.

[0056] According to some embodiments of this application, an isolation device 100 for a photovoltaic module 8 is provided on the isolation device 100 to avoid the junction box; and / or, the first contact surface 11 and / or the second contact surface 21 include an adsorption area 6 for suction cup adsorption.

[0057] The junction box on the photovoltaic module 8 carries functions such as circuit connection and electrical conversion. In the production process, the isolation device 100 is equipped with a avoidance area 5 to avoid direct collision or squeezing between the junction box and the isolation device 100. Without the avoidance area 5, the junction box may be damaged due to contact with the isolation device 100, resulting in short circuits, open circuits and other faults, which will affect the performance and service life of the entire photovoltaic module 8. The avoidance area 5 can effectively ensure the safety of the junction box, maintain the integrity of the module, and improve product quality and reliability.

[0058] In the production of modern photovoltaic modules 8, the application of automated equipment, the adsorption zone 6 enables the suction cup to be stably adsorbed on at least one of the first contact surface 11 and the second contact surface 21 of the isolation device 100. When the automated equipment needs to transport or move the isolation device 100 and the photovoltaic modules 8 placed on it, the suction cup can use the adsorption zone 6 to generate sufficient adsorption force to grab the isolation device 100, realizing precise and fast handling operations. In the automated production line, the suction cup moves the isolation device 100 and the modules from one station to another through the adsorption zone 6, which greatly improves production efficiency, reduces manual intervention, and reduces human error.

[0059] The isolation device 100 for photovoltaic module 8 according to some embodiments of this application further includes: heat dissipation holes 7, a plurality of heat dissipation holes 7 passing through the first isolation body 1 and / or the second isolation body 2, the openings at both ends of the heat dissipation holes 7 being located on the outer peripheral walls of the first isolation body 1 and / or the second isolation body 2 respectively, and the heat dissipation holes 7 being located on the non-first contact surface 11 and the non-second contact surface 21.

[0060] Multiple heat dissipation holes 7 penetrate at least one of the first isolation body 1 and the second isolation body 2, with the openings located on the outer peripheral wall, providing a channel for heat dissipation. When the photovoltaic module 8, after lamination, is placed on the isolation device 100 at a high temperature, heat will be transferred to the first isolation body 1 and the second isolation body 2 through thermal conduction. Due to the presence of the heat dissipation holes 7, air can form convection within the holes, and the air inside the heat dissipation holes 7 will flow naturally. Hot air will be discharged from one end of the hole, and cold air will enter from the other end, thereby accelerating heat dissipation. The heat dissipation holes 7 are located on the non-first contact surface 11 and the non-second contact surface 21, ensuring the integrity and stability of the first contact surface 11 and the second contact surface 21 when in contact with the photovoltaic module 8. This avoids the heat dissipation holes 7 being placed on the first contact surface 11 and the second contact surface 21, which would damage the flatness of the first contact surface 11 and the second contact surface 21, resulting in uneven contact area, increasing the local pressure between the photovoltaic module 8 and the isolation device 100, and thus affecting the support effect. By placing the heat dissipation holes 7 on the non-contact surface, it does not affect the normal support and contact of the isolation device 100 with the photovoltaic module 8, and can also achieve effective heat dissipation. When the protrusions 3 and / or recesses 4 on the first contact surface 11 and the second contact surface 21 come into contact with the photovoltaic module 8, the heat dissipation holes 7 will not interfere with their interaction, maintain good anti-adhesion performance, reduce the risk of photovoltaic module 8 breaking due to adhesion during subsequent loading and unloading, and improve production efficiency and product quality.

[0061] According to some embodiments of this application, the isolation device 100 for a photovoltaic module 8 has heat dissipation holes 7 disposed close to the first contact surface 11 and / or the second contact surface 21.

[0062] Because the heat dissipation holes 7 are positioned close to either the first contact surface 11 or the second contact surface 21, when the photovoltaic module 8 is placed on the isolation device 100, heat can be transferred more quickly from the module to the contact surface of the isolation device 100, and then dissipated through the nearby heat dissipation holes 7. According to the principle of heat conduction, heat will be transferred from the high temperature area to the low temperature area, and the closer the distance, the higher the efficiency of heat transfer. The proximity of the heat dissipation holes 7 to the contact surface shortens the heat conduction path and reduces energy loss during the heat transfer process. When the photovoltaic module 8 is at a high temperature after lamination and comes into contact with the first contact surface 11 or the second contact surface 21, heat is quickly conducted to the first contact surface 11 or the second contact surface 21. The nearby heat dissipation holes 7 can promptly remove this heat through air convection, which can accelerate the cooling speed of the photovoltaic module 8 and enable it to reach the appropriate operating temperature more quickly. This effectively avoids adverse effects on the performance of the module due to prolonged exposure to high temperatures, such as preventing a decrease in the photoelectric conversion efficiency of the solar cells.

[0063] According to some embodiments of this application, the isolation device 100 for a photovoltaic module 8 has a heat dissipation hole 7 constructed as a straight hole and the heat dissipation hole 7 extends along a second direction of the first isolation body 1.

[0064] The heat dissipation hole 7 is constructed as a straight hole and extends along the second direction of the first isolation body 1, providing a relatively smooth airflow channel. When the photovoltaic module 8 is placed on the isolation device 100 and generates heat, the hot air will rise due to the density difference. The straight hole structure allows the hot air to flow more directly from one end of the heat dissipation hole 7 to the other end, reducing the resistance during airflow. According to the principles of fluid mechanics, under the same pressure difference, the airflow speed of the straight hole is relatively fast, which can more efficiently expel hot air and simultaneously draw in cold air for replenishment, thereby accelerating heat exchange. The straight hole makes the airflow within the hole more stable. This improves heat dissipation efficiency, reduces the temperature of the photovoltaic module 8 and the isolation device 100 more quickly, ensures that the photovoltaic module 8 operates within a suitable temperature range, and avoids performance degradation due to high temperature. The heat dissipation holes 7 extend along the second direction of the first isolation body 1, which helps maintain the structural stability of the isolation device 100. The straight holes are relatively evenly distributed on the isolation device 100 and will not cause excessive weakening to the overall structure of the isolation device 100. The evenly distributed straight holes can make the stress distribution of the isolation device 100 more reasonable when it bears the weight of the photovoltaic module 8 and external forces, and avoid structural damage caused by local stress concentration.

[0065] Among them, such as Figure 6 The diagram shows the structure of the isolation device 100 with heat dissipation holes 7.

[0066] like Figure 7 As shown Figure 6 The front view of the structure shows that the heat dissipation holes 7 are spaced apart in the thickness direction of the isolation device 100.
