Most of the solar panels are installed in places where the sun shines and convert its light energy into electrical energy for use. However, solar panels may overheat under long-term exposure to sunlight, which in turn affects the efficiency of photovoltaic power generation.

The device is provided with a cooling plate. Water flows through the cooling plate to exchange heat with the solar panel to cool the solar panel. The heat exchanged water flows back into the water tank and is cooled by a cooler for continued use. The device is also provided with an annular water spray pipe for spraying water to cool the solar panel. At the same time, the solar panel can also be cleaned, thereby increasing the service life of the solar panel. The device is provided with a temperature sensor for sensing the temperature of the solar panel through the temperature sensor. The device can choose to use the cooling plate for cooling, the annular water spray pipe for cooling, or both the cooling plate and the annular water spray pipe for cooling. A combination of multiple cooling methods is used, with good cooling effect and high cooling efficiency.

[0004] When the prior art is used, although the cooling method can adopt combined cooling, it requires large energy consumption and has poor use effect.

[0005] Therefore, the present application provides a solar panel efficient cooling device to meet the demand. Utility Model Content

[0036] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a solar panel efficient cooling device, including a fixing frame 1, two front support columns 2 are symmetrically fixed at one end of the fixing frame 1, and two rear support columns 3 are symmetrically fixed at the other end, and a mounting plate 5 inclined toward one side is installed on the front support columns 2 and the rear support columns 3. In specific implementation, the top ends of the two front support columns 2 are rotatably connected to the bottom sides of the mounting plate 5, and two limiting slide grooves 501 are symmetrically opened on the top sides of the mounting plate 5, and the top ends of the rear support columns 3 are vertically inserted with telescopic rods 301, and the top ends of the two telescopic rods 301 are respectively slidably placed in the two limiting slide grooves 501 and are movably engaged. Therefore, the inclination state of the mounting plate 5 can be conveniently adjusted by adjusting the height of the telescopic rods 301 to meet the sun-facing requirements of photovoltaic power generation.

[0037] Among them, a plurality of positioning holes 302 are equidistantly provided on the side of the telescopic rod 301 along the length, and a positioning bolt 303 is provided on one side of the top end of the rear support column 3. The positioning bolt 303 penetrates into the rear support column 3 and is plugged and fixed with the positioning hole 302, so that the telescopic rod 301 after the length is adjusted can be fixed by plugging and fixing the positioning bolt 303 with the positioning hole 302.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the upper end surface of the mounting plate 5 is provided with a mounting groove 502 for fixing the photovoltaic panel 6, and a heat dissipation channel 9 is provided inside the mounting plate 5. The heat dissipation channel 9 and the bottom of the mounting groove 502 are separated by a heat conducting plate 10, wherein the heat dissipation channel 9 is distributed in an S-shaped manner in a zigzag manner inside the mounting plate 5, and a plurality of heat dissipation fins 1001 are fixed on the lower end surface of the heat conducting plate 10, and the heat dissipation fins 1001 pass through the distribution gaps of the heat dissipation channel 9 and extend out of the lower end surface of the mounting plate 5. Therefore, the heat of the photovoltaic panel 6 can be conducted away through the heat conducting plate 10 and the heat dissipation fins 1001.

[0039] A fixing plate 4 is fixed to one end of the fixing frame 1, and a water tank 7 is mounted on the fixing plate 4. Delivery pipes 8 are symmetrically fixed to both ends of the water tank 7, and two delivery pipes 8 are respectively connected to both ends of the heat dissipation channel 9. In specific implementation, a water pump and a radiator are arranged in the water tank 7, and the water pump output port is connected to a delivery pipe 8. A water inlet 902 and a water outlet 903 are respectively arranged at both ends of the heat dissipation channel 9, and the water inlet 902 and the water outlet 903 are respectively fixed to two opposite corners of the lower end surface of the mounting plate 5, and two delivery pipes 8 are respectively connected to the water inlet 902 and the water outlet 903 to form a cooling water flow loop with the water tank 7, so that the heat on the heat conducting plate 10 can be further taken away by water cooling through the water tank 7, the delivery pipe 8 and the heat dissipation channel 9.

[0040] At the same time, a driving cavity 901 is only provided in the middle of the heat dissipation channel 9, and the driving cavity 901 is located in the middle of the mounting plate 5, and a fan 11 is installed in the middle of the lower end surface of the mounting plate 5. The shaft of the fan 11 extends into the driving cavity 901 and is installed with blades 12, so that when the cooling water in the heat dissipation channel 9 flows through the driving cavity 901, it will drive the fan 11 to rotate by impacting the blades 12, thereby driving the air flow to take away the heat on the heat dissipation fins 1001, thereby realizing air-cooled heat dissipation.

[0041] The utility model provides a working principle. The solar panel high-efficiency cooling device can fix the photovoltaic panel 6 in the installation groove 502 when in use, and then start the water pump in the water tank 7, use the delivery pipe 8 and the heat dissipation channel 9 to circulate the cooling water in the installation plate 5, and cooperate with the heat conduction plate 10 to take away the heat of the photovoltaic panel 6, so as to realize water-cooled heat conduction heat dissipation.

[0042] At the same time, when the cooling water in the heat dissipation channel 9 flows through the driving cavity 901, it will drive the fan 11 to rotate by impacting the blades 12. At this time, when the heat conduction plate 10 uses the heat dissipation fins 1001 to dissipate heat, the rotating fan 11 will further take away the heat on the heat dissipation fins 1001 by driving the air flow, thereby realizing air-cooled heat dissipation.

[0043] In summary, the device can not only adopt dual heat dissipation of water cooling and air cooling, with good heat dissipation effect, but also can drive the start of air cooling during water cooling, which can effectively reduce heat dissipation energy consumption, save energy and reduce heat dissipation costs.

[0044] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
