[0048] Summary 2: Compared with the prior art, the synergistic effect of the coarse filter 811, the fine filter 812 and the adsorption layer 813 can effectively remove various impurities in the coolant, including larger particles of impurities, fine particles of impurities, tiny metal ions and chemical precipitates, which greatly improves the purity of the coolant, ensures that the thermal conductivity of the coolant is not affected by impurities, and maintains a good heat dissipation effect. When the impurities accumulate to a certain extent, the automatic drain valve 82 opens, and the impurities in the multi-layer filter mechanism 81 are discharged from the filter device through the outlet of the automatic drain valve 82 and the drain pipe under the action of gravity and coolant pressure.

[0049] refer to Figure 4-Figure 9 As shown, the heat regulating component 9 is used to reduce the temperature difference between different parts of the photovoltaic cell and significantly improve the heat dissipation uniformity;

[0051] Summary 3: Compared with the prior art, personnel drive the connecting shaft 91 to rotate, thereby driving the heat-spreading fins 92 to rotate around the connecting shaft 91, and adjusting the angle between the heat-spreading fins 92 and the surface of the photovoltaic cell. For areas with higher temperatures, the heat-spreading fins 92 will be adjusted to an angle that is more conducive to absorbing and conducting heat, increasing the contact area with the photovoltaic cell or optimizing the heat conduction path. For areas with lower temperatures, the heat-spreading fins 92 will appropriately adjust the angle to reduce excessive heat transfer, thereby achieving a more uniform distribution of heat on the surface of the photovoltaic cell.

[0052] The following is the working process and principle of the above embodiment:

[0053] The initial state is as follows:

[0054] The working steps are as follows: first, start the pump body 5, and the pump body 5 injects the coolant in the refrigeration box 4 into the heat exchange tube 2. When the coolant flows in the heat exchange tube 2, it absorbs the heat emitted by the photovoltaic cell equipment. After absorbing the heat, the coolant will flow back to the refrigeration box 4 for cooling. The cooled coolant is injected into the heat exchange tube 2 by the pump body 5 again, and this cycle is repeated to achieve continuous heat dissipation of the photovoltaic cell equipment. When the coolant flows at a high speed in the heat exchange tube 2, it impacts the driving blade 72, and the driving blade 72 drives the rotating rod 71 to rotate. The rotation of the rotating rod 71 drives the cooling fan 73 to run at a high speed. The rotation of the cooling fan 73 accelerates the flow of air. According to the principle of convection heat transfer, the air flow rate The faster it is, the greater the heat transfer coefficient with the surface of the heat exchange tube 2 is, and the heat on the surface of the heat exchange tube 2 can be taken away more quickly, thereby improving the heat dissipation efficiency. This method of using the kinetic energy of the coolant flow to drive the cooling fan 73 does not require an additional power source and realizes effective energy utilization. The airflow generated by the cooling fan 73 not only dissipates heat to the heat exchange tube 2, but also blows on the surface of the photovoltaic cell equipment to a certain extent, helping to reduce its temperature and maintain a stable working environment for the photovoltaic cell equipment. While dissipating the heat, the heat dissipation hole 11 is connected to the interior of the shell 1 to promote the discharge of internal hot air, and the exhaust filter 10 also filters dust and impurities in the air to prevent them from entering the interior of the radiator.

[0055] After the coolant flows out of the refrigeration box 4, it enters the multi-layer filtering mechanism 81 through the connecting pipe 6. First, impurities with larger particles are intercepted by the coarse filter screen 811 and cannot continue to flow with the coolant. Then, the coolant preliminarily filtered by the coarse filter screen 811 continues to flow forward, and impurities with fine particles are further filtered by the fine filter screen 812. Finally, the coolant filtered by the fine filter screen 812 flows through the adsorption layer 813. The special adsorption material in the adsorption layer 813 can effectively adsorb the tiny metal ions and chemical precipitates in the coolant, so that the coolant is fully purified. The purified coolant flows out of the filtering device and continues to enter the pump body 5, and then is pumped to the heat exchange tube 2 to complete the circulation process of the coolant. Through the synergistic effect of the coarse filter screen 811, the fine filter screen 812 and the adsorption layer 813, various impurities in the coolant can be effectively removed, including impurities with larger particles, fine particle impurities, tiny metal ions and chemical precipitates, greatly improving the purity of the coolant, ensuring that the heat conduction performance of the coolant is not affected by impurities, and maintaining a good heat dissipation effect. When the impurities accumulate to a certain extent, the automatic sewage discharge valve 82 is opened. Under the action of gravity and coolant pressure, the impurities in the multi-layer filtering mechanism 81 pass through the outlet of the automatic sewage discharge valve 82 and are discharged from the filtering device through the sewage discharge pipe. During cleaning, the rotating motor 85 drives the self-cleaning brush 83 to rotate, so that the self-cleaning brush 83 is in full contact with the surfaces of the coarse filter screen 811 and the fine filter screen 812, and the impurities attached to the filter screen are brushed off. The impurities brushed off settle to the bottom of the filtering device under the action of the coolant flow and wait to be discharged during the next sewage discharge process, reducing the frequency and workload of manual cleaning, reducing the labor and time costs, improving the maintenance convenience and reliability of the equipment, and having good economic benefits and practical application value.

[0056] When the pump body 5 is started, the high-precision temperature sensors 94 distributed at key positions on the surface of the photovoltaic cell monitor the temperature of various parts of the cell in real time, and transmit the collected temperature data to the central controller. After receiving the data from the temperature sensor, the central controller analyzes and processes the data. According to the analysis results, the central controller sends a corresponding instruction to the output motor 93 of the heat-spreading fin 92, instructing the motor to adjust the angle of the heat-spreading fin 92. After receiving the instruction from the central controller, the output motor 93 drives the connecting shaft 91 to rotate, thereby driving the heat-spreading fin 92 to rotate around the connecting shaft 91, adjusting the angle between the heat-spreading fin 92 and the surface of the photovoltaic cell. For areas with higher temperatures, the heat-spreading fin 92 will be adjusted to be more conducive to absorbing and conducting heat. The angle of the heat fin 92 is adjusted appropriately to increase the contact area with the photovoltaic cell or optimize the heat conduction path. For areas with lower temperatures, the heat-averaging fins 92 will adjust the angle appropriately to reduce excessive heat transfer, thereby achieving a more uniform distribution of heat on the surface of the photovoltaic cell. In the process of the coolant flowing through the heat exchange tube 2, due to the presence of the internal spiral spoiler 95, the coolant is forced to form a spiral flow. This spiral flow increases the contact area and contact time between the coolant and the inner wall of the heat exchange tube 2, so that the coolant can more fully absorb the heat transferred from the photovoltaic cell by the heat exchange tube 2, thereby improving the uniformity of heat exchange. At the same time, the coolant can also take away the heat more evenly during the spiral flow, further promoting the uniform distribution of the surface temperature of the photovoltaic cell.
