Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic support cooling system and a control method for the photovoltaic support cooling system. Background Technology

[0002] Solar photovoltaic (PV) power generation, as a clean and renewable energy source, is increasingly widely used. However, the photoelectric conversion efficiency of PV panels is highly sensitive to operating temperature, typically decreasing significantly as panel temperature rises. In summer or high-temperature regions, intense sunlight and high ambient temperatures can cause PV panel surface temperatures to exceed 70°C, resulting in a power generation efficiency loss of 15% to 25%. This temperature increase not only affects the power generation efficiency of PV power plants but also directly reduces economic benefits.

[0003] Currently, the main technologies for cooling photovoltaic (PV) panels include air cooling and water cooling. Air cooling relies on airflow for heat dissipation, but its effectiveness is limited in windless or lightly windy environments, failing to effectively reduce the PV panel temperature. Water cooling typically uses external spray systems, which, while effective in lowering panel temperature, has several drawbacks. First, water cooling systems require additional water pipes, spray nozzles, and related fixing devices to be laid outside the PV support structure, increasing installation complexity, occupying extra space, and affecting the overall aesthetics of the roof. Furthermore, over long-term use, if the water is hard, scale can form on the PV panel surface, affecting light transmittance and reducing power generation efficiency. Additionally, because the water pipes and joints are exposed, they are subject to long-term exposure to ultraviolet radiation, high temperatures, wind, and rain, potentially leading to aging, cracking, or detachment, thus posing potential safety hazards.

[0020] Solar photovoltaic (PV) power generation, as a clean and renewable energy source, is increasingly widely used. However, the photoelectric conversion efficiency of PV panels is highly sensitive to operating temperature, typically decreasing significantly as panel temperature rises. In summer or high-temperature regions, intense sunlight and high ambient temperatures can cause PV panel surface temperatures to exceed 70°C, resulting in a power generation efficiency loss of 15%-25%. This temperature increase not only affects the power generation efficiency of PV power plants but also directly reduces economic benefits.

[0021] Currently, the main technologies for cooling photovoltaic (PV) panels include air cooling and water cooling. Air cooling relies on airflow for heat dissipation, but its effectiveness is limited in windless or lightly windy environments, failing to effectively reduce the PV panel temperature. Water cooling typically uses external spray systems, which, while effective in lowering panel temperature, has several drawbacks. First, water cooling systems require additional water pipes, spray nozzles, and related fixing devices to be laid outside the PV support structure, increasing installation complexity, occupying extra space, and affecting the overall aesthetics of the roof. Furthermore, over long-term use, if the water is hard, scale can form on the PV panel surface, affecting light transmittance and reducing power generation efficiency. Additionally, because the water pipes and joints are exposed, they are subject to long-term exposure to ultraviolet radiation, high temperatures, wind, and rain, potentially leading to aging, cracking, or detachment, thus posing potential safety hazards.

[0022] To address the aforementioned technical problems, this application proposes a photovoltaic support cooling system. Please refer to [link / reference needed]. Figures 1 to 3In one embodiment of this application, the photovoltaic support cooling system includes a photovoltaic guide rail 100 and a water supply pipe 200. The photovoltaic guide rail 100 includes a support portion 110 and a receiving cavity 120. The support portion 110 is used to connect with the photovoltaic panel, and the receiving cavity 120 has a receiving opening 130 on the side facing the photovoltaic panel. The water supply pipe 200 includes a water supply pipe body 210 and a water spray nozzle 220. The water supply pipe body 210 is disposed in the receiving cavity 120, and the water spray nozzle 220 is opened on the periphery of the water supply pipe body 210 and extends toward the receiving opening 130, so that water in the water supply pipe body 210 can be sprayed toward the photovoltaic panel.

[0023] The technical solution of this application adopts a method in which a water supply pipe 210 is set inside a receiving cavity 120, and a water spray nozzle 220 is opened on the periphery of the water supply pipe 210 and passes through the receiving opening 130, so that the water in the water supply pipe 210 is sprayed onto the photovoltaic panel. This method can achieve cooling and heat dissipation of the photovoltaic panel without adding external devices. It has high integration and is easy to use, avoiding the space occupation and installation complexity of traditional water cooling systems. It is conducive to improving the water spray cooling efficiency of the photovoltaic power station, thereby improving the power generation efficiency and safety of the photovoltaic power station.

[0024] Please see Figure 1 In one embodiment, the number of water nozzles 220 is at least three, and the at least three water nozzles 220 are spaced apart along the axial direction of the water supply pipe 210. This technical solution, by setting at least three water nozzles 220 spaced apart along the axial direction of the water supply pipe 210, effectively ensures that the water flow can evenly cover all areas of the photovoltaic panel, significantly improving the heat dissipation effect and avoiding energy loss caused by localized overheating. The reasonable distribution of the water nozzles 220 improves the overall water flow coverage, keeping the surface temperature of the photovoltaic panel in a relatively balanced state, thereby improving the power generation efficiency of the photovoltaic system. Through this layout, the water flow distribution is more uniform, helping to reduce water waste and achieve efficient use of water resources, thereby reducing operation and maintenance costs and improving the long-term stability and reliability of the system.

[0025] Please see Figure 2In one embodiment, the cross-sectional shape of the receiving cavity 120 along the direction perpendicular to the axis of the water supply pipe 200 is semi-circular or U-shaped, with the semi-circular or U-shaped opening facing the photovoltaic panel. This embodiment, by using a semi-circular or U-shaped cross-sectional shape for the receiving cavity 120 and facing the photovoltaic panel, effectively guides the water flow to evenly cover the surface of the photovoltaic panel, thereby improving the cooling effect. The water flow can better contact the photovoltaic panel, avoiding localized overheating and ensuring that the temperature of the photovoltaic panel remains within a reasonable range, thus improving the system's heat dissipation efficiency. This technical solution also reduces ineffective water waste, enabling more efficient use of water resources and further improving the overall power generation efficiency of the photovoltaic power station. Simultaneously, the semi-circular or U-shaped structure increases the stability of water flow guidance, reduces unevenness during spraying, and enhances the system's reliability and long-term stability.

[0026] Please see Figure 1 In one embodiment, the water supply pipe body 210 includes a water guide pipe section 211 and a spray pipe section 212 that are interconnected. A spray nozzle 220 is located in the spray pipe section 212, and the water guide pipe section 211 is used to connect to the water source. This technical solution divides the water supply pipe body 210 into a water guide pipe section 211 and a spray pipe section 212, and through their interconnection, ensures that water flows smoothly from the water source into the spray pipe section 212, rationally controlling the water flow speed and pressure, and effectively improving the working efficiency of the spray nozzle 220. The connection between the water guide pipe section 211 and the water source ensures the stability of the water supply, avoiding water flow interruptions or fluctuations, further improving the reliability of the system. By rationally setting the position of the spray nozzle 220, the water flow can be evenly distributed on the surface of the photovoltaic panel, enhancing the heat dissipation effect and improving the utilization efficiency of the photovoltaic panel. This technical solution simplifies the system structure, reduces energy consumption and maintenance costs, and simultaneously improves the stability and long-term operational reliability of the system.

[0027] Please see Figure 1In one embodiment, the photovoltaic support cooling system further includes a valve 300 and a water pump 400. The water guide pipe section 211 includes a first pipe section 2111 and a second pipe section 2112 that are interconnected. A water pump 400 is installed between the second pipe section 2112 and the spray pipe section 212, and a valve 300 is installed between the second pipe section 2112 and the first pipe section 2111. This technical solution achieves precise control and regulation of water flow by installing a valve 300 and a water pump 400 in the water guide pipe section 211, effectively improving the working efficiency of the photovoltaic support cooling system. The valve 300 allows the water flow between the first pipe section 2111 and the second pipe section 2112 to be flexibly adjusted according to actual needs, ensuring that the water flow maintains the optimal flow rate under different working conditions. The water pump 400 enables the water flow to be efficiently delivered to the spray pipe section 212, thereby ensuring that the water flow is evenly distributed on the surface of the photovoltaic panel, enhancing the heat dissipation effect and improving the power generation efficiency of the photovoltaic system. This flexible water flow control method not only optimizes water resource utilization and reduces energy consumption, but also improves the system's response speed and adaptability, enabling it to maintain stable and efficient operation in different environments.

[0028] Please see Figure 1 In one embodiment, the photovoltaic support cooling system also includes a control device electrically connected to a water pump 400. The control device controls the opening and closing of the water pump 400. It is also electrically connected to a valve 300, which controls its opening and closing as well. This technical solution achieves intelligent management of the water pump 400 and valve 300 by introducing a control device, effectively improving the automation level of the photovoltaic support cooling system. The electrical connection between the control device and the water pump 400 allows the system to automatically adjust the water flow according to the temperature changes of the photovoltaic panels, ensuring real-time water supply and control, avoiding manual intervention, and improving work efficiency. The connection with the valve 300 makes water distribution more flexible, allowing for precise adjustment of water volume according to actual needs, further optimizing the heat dissipation effect. This technical solution not only improves the system's stability and response speed but also reduces energy waste, lowers operating costs, and enhances the system's reliability and longevity.

[0029] Please see Figure 1In one embodiment, the photovoltaic support cooling system further includes a temperature detection device 500, which is installed in the water pipe section 211. The temperature detection device 500 detects the ambient temperature and the photovoltaic panel temperature, and outputs information on both. This technical solution, by introducing the temperature detection device 500, achieves real-time temperature monitoring of the photovoltaic support cooling system, providing crucial data support for intelligent system adjustment. The temperature detection device 500, installed in the water pipe section 211, can simultaneously detect the ambient temperature and the photovoltaic panel temperature, transmitting this temperature information to the control device. Based on this real-time temperature data, the control device can automatically adjust the operating status of the water pump 400 and the opening and closing of the valve 300, ensuring that the water supply and regulation match the actual temperature requirements. Thus, the system not only achieves efficient cooling but also responds quickly to environmental changes, avoiding unnecessary energy waste and improving the system's energy utilization rate. Furthermore, the addition of the temperature detection device 500 makes the system more intelligent, enhancing the adaptability and reliability of the photovoltaic support cooling system and improving overall performance.

[0030] Please see Figure 1 In one embodiment, the control device is also electrically connected to the temperature detection device 500. The control device compares the received ambient temperature and photovoltaic panel temperature information with a preset temperature threshold, and controls the opening or closing of the water pump 400 and valve 300 based on the comparison result. This technical solution effectively improves the automation level and response speed of the photovoltaic support cooling system through real-time monitoring by the temperature detection device 500 and intelligent adjustment by the control device. It enables the system to dynamically adjust the water flow rate according to changes in ambient and photovoltaic panel temperatures, ensuring that the photovoltaic panels are always kept within the optimal operating temperature range, thus improving the cooling effect and photovoltaic power generation efficiency. Simultaneously, the optimization of the temperature control system reduces energy waste, improves energy utilization efficiency, and provides a guarantee for the long-term stable operation of the photovoltaic system.

[0031] Please see Figure 1 In one embodiment, the photovoltaic support cooling system further includes a humidity detection device 600, which is disposed in the water guide pipe section 211. The humidity detection device 600 is used to detect the ambient humidity and output the ambient humidity information. This technical solution, through the real-time monitoring of the humidity detection device 600 and the intelligent adjustment of the control device, enables the photovoltaic support cooling system to dynamically adjust the cooling strategy according to changes in ambient humidity, optimize water flow management, reduce excessive evaporation and energy waste, improve cooling efficiency and system operational stability, and enhance the working performance and service life of the photovoltaic panels under different climatic conditions.

[0032] Please see Figure 1In one embodiment, the control device is also electrically connected to a humidity detector. The control device compares the received ambient humidity information with a preset humidity threshold and controls the opening or closing of the water pump 400 and valve 300 based on the comparison result. This technical solution, through the electrical connection between the control device and the humidity detector 600, enables the system to adjust its cooling strategy in real time according to the ambient humidity, avoiding water waste or affecting the cooling effect of the photovoltaic panels when the humidity is too high. This optimizes the system's energy efficiency and ensures stable operation of the photovoltaic support under different humidity conditions while maintaining optimal cooling performance.

[0033] Please see Figure 3 In one embodiment, the photovoltaic support cooling system further includes a pressure block 700. The photovoltaic panels are laid on the photovoltaic guide rail 100, and the connection points of adjacent photovoltaic panels are fixed by the pressure block 700. This technical solution, by fixing adjacent photovoltaic panels with pressure blocks, enhances the overall stability of the photovoltaic panels, reduces the risk of displacement or damage caused by external forces, and effectively reduces the temperature of the photovoltaic panels through good thermal conductivity. This improves the working efficiency and power generation capacity of the photovoltaic panels, extends their service life, and enhances the reliability and long-term operating performance of the system.

[0034] Furthermore, to achieve the above objectives, this application also proposes a control method for a photovoltaic support cooling system. In one embodiment, please refer to...

Through this step, the system can accurately obtain temperature changes, providing accurate data support for subsequent temperature control adjustments, ensuring that the photovoltaic panel operates within a suitable temperature range, and avoiding energy efficiency loss due to excessive temperature.

[0036] S12. Compare the received ambient temperature and photovoltaic panel temperature information with the preset temperature threshold.

[0037] In step S12, the control device compares the received ambient temperature and photovoltaic panel temperature with a preset temperature threshold, and makes intelligent decisions based on different temperature conditions to determine whether cooling measures need to be initiated. Through this step, the system can automatically respond to temperature changes without manual intervention, effectively avoiding excessive or ineffective cooling when the temperature is too high, thereby maximizing energy utilization efficiency and system stability.

[0038] S13. Control the opening or closing of the water pump and valves based on the comparison results.

[0039] In step S13, the control device intelligently adjusts the status of the water pump and valves based on the temperature comparison results, precisely controlling the water flow to ensure that the photovoltaic panels are always within the optimal operating temperature range. Through this step, the system can adjust the cooling strategy in real time according to the temperature, avoiding damage to the photovoltaic panels caused by excessive temperature fluctuations, thereby improving power generation efficiency and equipment lifespan, and ensuring the efficient operation of the photovoltaic support cooling system.

[0044] S24. Detect ambient humidity and output ambient humidity information.

[0045] In step S24, the photovoltaic support cooling system monitors the ambient humidity in real time using a humidity sensor and transmits the detected humidity information to the control device, ensuring that the system has a comprehensive understanding of the ambient humidity. This step allows the system to respond promptly to humidity changes, preventing excessive cooling in high humidity conditions, ensuring efficient system operation, and reducing water waste.

[0046] S25. Compare the received ambient humidity information with the preset humidity threshold.

[0047] In step S25, the control device compares the received ambient humidity information with a preset humidity threshold to determine whether the current humidity exceeds the set threshold, and then decides whether to activate the cooling system. Through this step, the system can make intelligent decisions based on actual environmental conditions, automatically adjust the cooling operation, avoid resource waste or equipment damage caused by excessively high or low humidity, and improve the system's response efficiency and accuracy.

[0048] S26. Control the opening or closing of the water pump and valves based on the comparison results.

[0049] In step S26, the control device controls the opening and closing of the water pump and valves based on the humidity comparison results, precisely adjusting the water flow to ensure the system performs cooling operations under appropriate humidity conditions.
