Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation system technology, and particularly to the field of photovoltaic panel heat dissipation and cooling technology, specifically referring to a photovoltaic panel multi-mechanism heat dissipation and cooling system. Background Technology

[0002] With the continuous development of the new energy industry, photovoltaic power generation systems have been widely used in various scenarios such as building rooftops, photovoltaic agricultural sheds, and transportation facilities. When photovoltaic modules are exposed to direct sunlight for extended periods, their surface temperature typically rises significantly. Excessive temperature directly affects the power generation efficiency and lifespan of the photovoltaic modules. Research shows that for every 1°C increase in photovoltaic cell temperature, its conversion efficiency decreases by approximately 0.3% to 0.5%. Therefore, effectively reducing the operating temperature of photovoltaic modules is one of the key technologies for improving their power generation efficiency and extending their service life.

[0003] Currently, the main technical methods for addressing the heat dissipation problem of photovoltaic panels are as follows:

[0004] 1) Natural ventilation cooling method

[0005] Passive heat dissipation is achieved by setting photovoltaic panels at a certain angle or elevating them to improve airflow beneath them. This method has a simple structure, but its heat dissipation effect is limited, especially in high-temperature, windless environments where efficiency is low.

[0006] 2) Forced air cooling system

[0007] Fans or blowers can be used to enhance air convection and improve heat dissipation. However, this method suffers from "inefficient hot air flow" in hot and dry regions, and the long-term operation of fans will result in additional energy consumption.

[0008] 3) Water-cooled / spray cooling system

[0009] Spraying water mist onto the surface of photovoltaic panels at regular intervals allows heat to be carried away through evaporation, resulting in high cooling efficiency, especially in hot environments. However, existing systems generally suffer from problems such as unreasonable structure, uncontrollable water use, and lack of water resource recycling, leading to high operating costs and serious resource waste.

[0010] 4) Rainwater utilization system

[0011] In some green buildings, there are designs that divert roof rainwater for non-potable purposes, but few integrate it with photovoltaic heat dissipation systems, making it impossible to achieve systematic and intelligent temperature control management.

[0012] Therefore, it is desirable to provide a photovoltaic panel heat dissipation and cooling system that can use a combination of multiple cooling methods to cool the photovoltaic panel, make full use of water resources, and achieve energy efficiency. Utility Model Content

[0054] In use, this utility model is placed at a high place, such as on a roof, and the collection tank 9 is placed on the ground. First, the photovoltaic panel 1 generates electricity normally. The temperature of the photovoltaic panel 1 is detected by the temperature sensor and sent to the heat dissipation controller 10. When the temperature rises due to strong sunlight, the photovoltaic panel 1 is tilted and suspended by the photovoltaic bracket 2, which improves the airflow below it and achieves passive heat dissipation. Second, when the temperature of the photovoltaic panel 1 is higher than, for example, 45°C, the heat dissipation controller 10 controls the atomizing nozzle 5 to spray and the fan 3 to start. Cold water from the water tank 6 passes through the cold water pipe 4 and is sprayed out as water mist from the atomizing nozzle 5. The cold water can cool the photovoltaic panel 1 once when it flows through the cold water pipe 4, and it can also cool the photovoltaic panel 1 again when it is sprayed out as water mist from the atomizing nozzle 5, thereby reducing the ambient air temperature. The fan 3 is used to assist airflow circulation, so that the cooled air can fully contact the photovoltaic panel 1 and carry away the heat, achieving a combined cooling effect of water cooling and air cooling.

[0055] The condensate on the back of the photovoltaic panel 1 flows downward to the left along the tilt direction of the photovoltaic panel 1, and then flows down into the return channel 8. The water in the return channel 8 then flows into the collection tank 9 for collection and storage. The water collected and stored in the collection tank 9 can be used as a secondary water source for subsequent irrigation, cleaning or secondary circulation spraying. The water storage tank 6 can directly store rainwater, and can also be replenished with municipal tap water through the water supply pipe 7. If the other end of the water supply pipe 7 is connected to the collection tank 9, the water stored in the collection tank 9 can also be replenished through the water supply pipe 7.

[0056] Therefore, this invention achieves natural ventilation cooling by tilting the photovoltaic panels and elevating them via photovoltaic supports; when strong sunlight causes temperature increases, water cooling / spray cooling is achieved through cold water pipes and misting nozzles; forced air cooling is achieved by enhancing air convection and increasing heat dissipation speed through fans; condensate is returned to a collection tank through a return channel, realizing the recycling of water resources; the water used for water cooling / spray cooling is mainly collected from rainwater, supplemented by tap water, and can also be stored in a collection tank, making it energy-efficient and highly effective.

The photovoltaic panel controller is electrically connected to the photovoltaic panel to collect the output power of the photovoltaic panel and is signal-connected to the heat dissipation controller to send the output power of the photovoltaic panel to the heat dissipation controller. The fan is also electrically connected to the photovoltaic panel. The heat dissipation controller is used to control the fan to use either the photovoltaic panel or the mains power supply according to the output power of the photovoltaic panel.
