Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic panel technology, specifically a solar photovoltaic panel with a cooling structure. Background Technology

[0002] When photovoltaic panels are in use, they need to be exposed to sunlight. The sunlight will cause the photovoltaic panels to generate heat, which will cause the temperature of the photovoltaic panels to rise. This is especially noticeable in summer or in hot regions. High temperatures will affect the power generation efficiency of photovoltaic panels; the higher the temperature, the lower the power generation efficiency.

[0003] For example, a solar photovoltaic panel with heat dissipation function (Announcement No.: CN218450034U) includes a water tank, a base plate, a support plate, a motor, a fixed frame, spacers, and a photovoltaic panel. This utility model provides a solar photovoltaic panel with heat dissipation function. By placing the solar panel on the base plate, the photovoltaic panel on the fixed frame can absorb solar energy and convert it into electrical energy. When the inside of the fixed frame is overheated, the heat absorption frame of the discharge block on it will absorb the internal temperature, causing the gas below the connecting frame to expand due to heat, pushing it upward. This, in turn, pushes open the sealing plate on the discharge plate through the connecting pipe, thereby connecting the coolant in the water tank to the water cooling pipe, which then spreads throughout the fixed frame, achieving a cooling effect. By improving the equipment structure, the solar panel can automatically perform water cooling when the output line is overheated, providing a cooling and protection function for its internal structure.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it is known that when the aforementioned equipment is used, the water tank is placed on top of the fixed frame. The water tank is exposed to the sun, and the temperature of the coolant inside the water tank is prone to rise. As the temperature of the coolant rises, its cooling efficiency will gradually decrease. Therefore, we need to propose a solar photovoltaic panel with a cooling structure. Utility Model Content

A heat exchange tube 52 is installed at the bottom of the silicone heat-conducting sheet 51. The liquid inlet end of the heat exchange tube 52 is fixedly connected to a liquid inlet pipe 54. One end of the liquid inlet pipe 54 is fixedly connected to a submersible pump 55. The liquid outlet end of the heat exchange tube 52 is fixedly connected to a liquid storage tank 56 through a pipe. The liquid storage tank 56 is fixedly installed inside the mounting bracket 1 to prevent direct sunlight exposure to the liquid storage tank 56. 6. The submersible pump 55 is fixedly installed inside the liquid storage tank 56. A refrigeration mechanism 6 for cooling the refrigerant inside the liquid storage tank 56 is installed at the bottom of the liquid storage tank 56. This allows the submersible pump 55 to draw the refrigerant from the liquid storage tank 56 and transport it through the liquid inlet pipe 54 to the heat exchange pipe 52. The refrigerant in the heat exchange pipe 52 circulates with the refrigerant in the liquid storage tank 56. The heat of the photovoltaic panel body 3 is exchanged with the heat of the refrigerant in the heat exchange pipe 52 through the silicone heat-conducting sheet 51, thereby cooling the bottom of the photovoltaic panel body 3 in the mounting base 2.

[0028] The bottom of the liquid storage tank 56 is provided with a through groove 59, and the refrigeration mechanism 6 is fixedly installed inside the through groove 59. The refrigeration mechanism 6 is located at the bottom of the liquid storage tank 56 to reduce the impact of the external environment on the refrigeration mechanism 6.

[0029] The refrigeration mechanism 6 includes a U-shaped frame 61, which is fixedly embedded inside the through slot 59. A thermoelectric cooler 62 is fixedly installed inside the U-shaped frame 61. A heat dissipation fin 63 is fixedly installed on the hot end of the thermoelectric cooler 62. A fan frame 64 is fixedly installed on the U-shaped frame 61 at the bottom of the heat dissipation fin 63. A fan body 65 is installed inside the fan frame 64 to accelerate the cooling of the heat dissipation fin 63. This facilitates the cooling of the refrigerant in the liquid storage tank 56 through the thermoelectric cooler 62. The fan body 65, together with the heat dissipation fin 63, dissipates heat from the hot end of the thermoelectric cooler 62, improving the cooling effect of the thermoelectric cooler 62 and keeping the refrigerant in the liquid storage tank 56 at a low temperature.

[0030] The cold end of the semiconductor cooling chip 62 faces the inside of the liquid storage tank 56. The heat dissipation fins 63 have heat dissipation grooves 67 on the side facing the fan body 65 to allow ventilation between the fins of the heat dissipation fins 63, which facilitates the acceleration of the heat dissipation effect of the heat dissipation fins 63. The fan frame 64 is located on the outside of the fan body 65 and a protective net 66 is fixedly installed to facilitate the protection of the fan body 65 through the protective net 66.

The heat exchange tube 52 is fixedly installed inside the heat exchange groove 53, which increases the contact area between the silicone heat-conducting sheet 51 and the heat exchange tube 52, thereby exchanging the heat of the photovoltaic panel body 3 with the heat of the refrigerant in the heat exchange tube 52 through the silicone heat-conducting sheet 51.

[0032] A heat insulation shell 57 is fixedly installed at the bottom of the mounting base 2. The silicone heat-conducting sheet 51 and the heat exchange tube 52 are located inside the heat insulation shell 57, which facilitates the heat insulation protection of the bottom of the heat exchange tube 52 through the heat insulation shell 57, reducing the impact of the external environment on the heat exchange tube 52.

The liquid level observation window 58 allows observation of the liquid level of the refrigerant in the liquid storage tank 56.

[0034] Working principle: When this utility model is used, the liquid storage tank 56 in the cooling mechanism 5 is installed inside the mounting bracket 1, which can avoid direct sunlight exposure to the liquid storage tank 56. The refrigerant in the liquid storage tank 56 is drawn by the submersible pump 55 and transported to the heat exchange tube 52 through the liquid inlet pipe 54. The refrigerant in the heat exchange tube 52 circulates with the refrigerant in the liquid storage tank 56. The heat of the photovoltaic panel body 3 is exchanged with the heat of the refrigerant in the heat exchange tube 52 through the silicone heat-conducting sheet 51, thereby cooling the bottom of the photovoltaic panel body 3 in the mounting base 2. It has the advantages of improving the photoelectric conversion efficiency of the photovoltaic panel body 3, slowing down the aging rate of the photovoltaic panel body, and extending its service life.

[0035] Meanwhile, the semiconductor cooling chip 62 in the cooling mechanism 6 at the bottom of the liquid storage tank 56 cools the refrigerant in the liquid storage tank 56, and the fan body 65, together with the heat dissipation fins 63, dissipates heat from the hot end of the semiconductor cooling chip 62, thereby improving the cooling effect of the semiconductor cooling chip 62 and keeping the refrigerant in the liquid storage tank 56 at a low temperature, which can improve the heat exchange and cooling efficiency of the refrigerant to the photovoltaic panel body 3.
