Technical Field
[0001] The invention relates to a photovoltaic component, in particular to a stable photovoltaic component based on metal back plate heat dissipation. Background Art
[0002] Photovoltaic module (solar module) is a solar cell module. Since the output voltage of a single solar cell is low, and the electrodes of unpackaged cells are easily detached due to environmental influences, a certain number of single cells must be sealed into photovoltaic modules in series and parallel to avoid corrosion of the cell electrodes and interconnections. Photovoltaic modules are divided into crystalline silicon solar cell modules and thin-film solar cell modules according to the materials of the solar cells.
[0003] The patent publication number CN118041230A discloses a cooling device for a solar cell assembly, which belongs to the field of photovoltaic power generation technology. It includes a support, a plurality of heat-conducting blocks and a heat-conducting wire. The support is used to install a solar cell panel. The plurality of heat-conducting blocks are arranged between the solar cell panel and the support. The plurality of heat-conducting blocks are at a certain distance from each other, and the plurality of heat-conducting blocks are fixedly connected to the back of the solar cell panel. The support is provided with a plurality of placement grooves, and the plurality of placement grooves correspond to the plurality of heat-conducting blocks one by one. The heat-conducting blocks are installed in the placement grooves. When the heat-conducting blocks are at room temperature, the end face of the heat-conducting blocks close to the solar cell panel is flush with the notch of the placement groove. When the heat-conducting blocks are at high temperature, the heat-conducting blocks are heated and expanded, and the end face close to the solar cell panel is higher than the depth of the placement groove. One end of the heat-conducting wire connects the plurality of heat-conducting blocks in series, and the other end of the heat-conducting wire is inserted into the ground. The present invention has the effect of reducing the operating cost of the entire solar device. This application conducts the heat of the solar panel to the ground through a heat conductive block.

DETAILED DESCRIPTION
[0029] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0030] Embodiment: A stable photovoltaic module based on metal backplane heat dissipation, such as Figure 1-Figure 6 As shown, it includes a support 1, a bracket 2, a solar panel body 3 and a heat dissipation component 4. The top of the support 1 is fixedly connected to the bracket 2 by bolts. At least two rows of solar panel bodies 3 are fixedly connected to the bracket 2. The solar panel bodies 3 are installed tilted with the left side higher and the right side lower. A heat dissipation component 4 is installed between the bottom of the solar panel body 3 and the support 1.
[0031] like Figure 5 and Figure 6As shown, the heat dissipation component 4 includes a condenser Ⅰ41, a water pump Ⅰ42, a connecting copper tube 43 and a finned aluminum plate 44. The condenser Ⅰ41 is fixedly connected to the rear side of the top of the support 1. The condenser Ⅰ41 is installed in parallel with the solar panel body 3. The water pump Ⅰ42 is fixedly connected to the left front side of the condenser Ⅰ41 through an adapter plate. The pumping end of the water pump Ⅰ42 is connected to the condenser Ⅰ41. The bottom of the solar panel body 3 is fixedly connected to the finned aluminum plate 44. The connecting copper tube 43 is connected through the finned aluminum plates 44. The connecting copper tube 43 is S-shaped and passes through all the finned aluminum plates 44. There are at least two overlapping positions between the finned aluminum plates 44 and each connecting copper tube 43. The upper port of the connecting copper tube 43 is connected to the water outlet of the water pump Ⅰ42, and the lower port of the connecting copper tube 43 is connected to the lower part of the condenser Ⅰ41.
[0032] When the photovoltaic module is working, the water pump Ⅰ42 and the condenser Ⅰ41 are controlled to start working, and the water pump Ⅰ42 pumps the coolant in the condenser Ⅰ41 into the connecting copper tube 43. The heat emitted by the solar cell panel body 3 is transferred to the finned aluminum plate 44. After the coolant enters the connecting copper tube 43, it flows along the connecting copper tube 43, takes away the heat on the finned aluminum plate 44, so that the temperature of the finned aluminum plate 44 is reduced, and the solar cell panel body 3 is cooled. After the coolant returns to the condenser Ⅰ41 through the bottom end of the connecting copper tube 43 for cooling, it is pumped into the connecting copper tube 43 again through the water pump Ⅰ42. This is repeated to dissipate the heat of the solar cell panel body 3. When the photovoltaic module does not need to dissipate heat, the water pump Ⅰ42 and the condenser Ⅰ41 are controlled to stop working.
[0033] like Figure 8 and Fig. 9 As shown, a reinforcement component 6 is also included. The reinforcement component 6 is installed on the bracket 2 below the solar panel body 3. The reinforcement component 6 is located below the joint of the front and rear solar panel bodies 3. The reinforcement component 6 includes a mounting shell 61, a connecting pipe 62, a branch pipe 63, a suction cup 64 and a threaded plug 65. The mounting shell 61 is fixedly installed on the bracket 2 below the solar panel body 3. A connecting pipe 62 is installed in the mounting shell 61. At least two branch pipes 63 are installed on the front and rear sides of the connecting pipe 62. The ends of the branch pipes 63 are connected to suction cups 64. The suction cups 64 on both sides of the same connecting pipe 62 are located below the front and rear adjacent solar panel bodies 3. The bottom end of the connecting pipe 62 is connected to a threaded plug 65 through threads.
[0034] After the solar panel body 3 is installed on the bracket 2, the threaded plug 65 is turned counterclockwise to move the threaded plug 65 to the lower left. At this time, due to the effect of air pressure, the suction cup 64 is closed, so that the suction cup 64 is adsorbed under the solar panel body 3 to adsorb the solar panel body 3. In this way, the solar panel body 3 can be installed more stably to cope with severe windy weather. When the solar panel body 3 needs to be removed, the threaded plug 65 is turned clockwise to move the threaded plug 65 to the upper left, and the suction cup 64 is opened to release the solar panel body 3.
[0035] like Figure 7 As shown, it also includes a heat dissipation acceleration component 5, which is installed below the solar panel body 3. The heat dissipation acceleration component 5 includes a mounting plate 51, a water pump II 52, a condenser II 53, a water pumping pipe 54, a cooling box 55, a shunt pipe 56 and a return pipe 57. The mounting plate 51 is fixedly arranged symmetrically front and back by bolts on the rear side of the bracket 2. The water pump II 52 is fixedly connected to the mounting plate 51 by bolts. The support 1 below the mounting plate 51 is fixedly connected to the condenser II 53. The bottom of the condenser II 53 The right side is higher than the left side, and a pumping pipe 54 is connected between the condenser II 53 and the pumping end of the water pump II 52. A cooling box 55 is installed at the bottom of the mounting shell 61. A shunt pipe 56 is connected between the top of two adjacent cooling boxes 55 and the water outlet end of the water pump II 52. The connecting copper tube 43 passes through the cooling box 55. The position where the connecting copper tube 43 passes through the cooling box 55 is sealed and connected, and the cooling box 55 and the connecting copper tube 43 are installed vertically. A return pipe 57 is connected to the bottom of the cooling box 55, and the return pipe 57 is connected to the condenser II 53.
[0036] When the solar panel body 3 is cooled, the water pump II 52 and the condenser II 53 are controlled to start working. The water pump II 52 draws the coolant in the condenser II 53 into the shunt pipe 56 through the pumping pipe 54, and then enters the cooling box 55 through the shunt pipe 56. The coolant entering the cooling box 55 dissipates the heat of the connecting copper tube 43, so that the coolant inside the connecting copper tube 43 can be cooled twice in the process of dissipating the heat of the solar panel body 3, thereby improving the heat dissipation effect of the solar panel body 3. The coolant entering the cooling box 55 returns to the condenser II 53 through the return pipe 57 under the action of gravity for cooling, so as to prepare for the subsequent cooling work. When the solar panel body 3 does not need to dissipate heat, the water pump II 52 and the condenser II 53 are controlled to stop working.
[0037] like Fig.10As shown, an edge clamping assembly 7 is also included. The edge clamping assembly 7 is symmetrically installed on the front and rear sides of the bracket 2. The edge clamping assembly 7 includes a guide rod 71 and a clamping plate 72. The guide rods 71 are a group of two and are symmetrically installed on the front and rear sides of the bracket 2. A clamping plate 72 is slidably connected to each group of guide rods 71. The clamping plate 72 is installed parallel to the solar panel body 3. The lower wall of the clamping plate 72 is clamped below the bracket 2, and the upper wall of the clamping plate 72 is clamped above the solar panel body 3.
[0038] After the solar panel body 3 is installed on the bracket 2, the clamping plate 72 is moved toward the solar panel body 3 so that the upper wall of the clamping plate 72 is clamped above the solar panel body 3, and then the clamping plate 72 is fixed to the bracket 2 by bolts. In this way, the edge of the solar panel body 3 can be fixed to prevent the solar panel body 3 from being lifted up in windy weather, and the solar panel body 3 is installed more firmly.
[0039] like Figure 3 As shown, it also includes a limit plate I8, a limit plate II9 and a reinforcing rib 10. A limit plate I8 is installed in the middle of the top of the bracket 2, the bottom of the first row of solar panel bodies 3 is in contact with the limit plate I8, a limit plate II9 is installed on the right side of the top of the support 1, and the bottom of the second row of solar panel bodies 3 is in contact with the limit plate II9. A reinforcing rib 10 is connected between the limit plate II9 and the support 1.
[0040] Before the solar panel body 3 is installed, when the solar panel body 3 is placed on the bracket 2, the bottom of the solar panel body 3 contacts the limit plate I8 and the limit plate II9, and the limit plate I8 and the limit plate II9 support the solar panel body 3, which can facilitate the installation of the solar panel body 3. The reinforcing rib 10 can strengthen the strength of the limit plate II9 to prevent the limit plate II9 from being affected by the gravity of the solar panel body 3.
[0041] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
