Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic modules, and in particular relates to a heat dissipation photovoltaic panel for a water surface wave floating photovoltaic module. Background Art

[0002] Water-based photovoltaic power stations generally refer to those with large water resources such as ponds, reservoirs, and lakes. They are mainly divided into pile-based fixed type and water-based floating type. With the continuous maturity of water-based floating technology, new materials, new technologies, and new processes continue to emerge, and construction costs continue to decrease. In addition, due to the advantages of water-based floating photovoltaic modules being closer to the water surface, the water cooling effect is more obvious, and the ability to adapt to changes in water surface height, water-based floating photovoltaic power stations are relatively widely used. In recent years, water-based floating photovoltaic power generation projects have become a new hot spot in the field of photovoltaic power generation, and installed capacity has shown rapid growth.

[0003] Among them, temperature will also have a great impact on the power generation efficiency of photovoltaic modules. When in a higher temperature range, the power generation efficiency will decrease by 0.45% for every 1°C increase in the temperature of the photovoltaic modules. When the temperature is very high at noon in summer, especially in plateau lakes, the heat generated by solar radiation and the heat generated during the photoelectric conversion process will increase the temperature of the photovoltaic modules, affecting the power generation efficiency and module life of the photovoltaic modules. At this time, if we want to make full use of the strong light resources, we also need to improve the heat dissipation efficiency of the water surface photovoltaic modules to ensure maximum power generation efficiency.

[0004] At the same time, since there are relatively more waves on a larger water surface, this is mainly because a wide water surface is more conducive to the flow of airflow, and wind speed is the most important driving factor of water waves; therefore, the present invention designs a heat dissipation photovoltaic panel for a water surface wave floating photovoltaic assembly. Summary of the invention

[0005] The purpose of the present invention is to provide a heat dissipation photovoltaic panel for a water surface wave floating photovoltaic module. Through the functions of the photovoltaic panel, the floating module and the heat dissipation channel, the waves of a large water surface can be used to provide an excellent heat dissipation effect for the water surface floating photovoltaic module, significantly improving the heat dissipation efficiency of the water surface photovoltaic module, and having the advantages of ensuring full utilization of sufficient light resources and maximizing power generation efficiency; solving the above-mentioned problem that the heat dissipation efficiency needs to be improved at noon in summer.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a heat dissipation photovoltaic panel for a water surface wave floating photovoltaic assembly, comprising a photovoltaic panel, a floating assembly and a heat dissipation channel; a photovoltaic cell is fixedly installed inside the photovoltaic panel; a heat conducting plate is sealedly installed on the back of the photovoltaic panel, and the bottom surface of the heat conducting plate is fixedly connected to a heat dissipation channel for collecting and storing water by utilizing water surface waves; a support frame and a floating assembly are also fixedly installed at the back frame of the photovoltaic panel, and the floating assembly increases the required buoyancy for the photovoltaic panel; the heat dissipation channel comprises a wave water storage tank, a water cooling channel and a drain outlet; wave water storage tanks for increasing the water level of the water storage are fixedly installed at both ends of the water cooling channel, and a drain outlet with a water level height difference is arranged in the middle of the water cooling channel; when water surface waves flow through, the waves will pass over the outer frame of the wave water storage tank and enter the interior thereof, achieving the effect of accumulating water volume and water level height; thereby, the water flow inside the wave water storage tank cannot flow into the water cooling channel and then flow out from the drain outlet; a relatively sufficient water cooling flow effect is provided for the photovoltaic panel; thereby significantly improving the heat dissipation efficiency.

[0008] As a preferred technical solution of the present invention, the outer side of the wave water storage tank is provided with an arc surface which is conducive to the impact of surface waves and the flow in; baffles are fixed at both ends of the wave water storage tank; this is conducive to allowing more water in the waves to flow in.

[0010] As a preferred technical solution of the present invention, a U-shaped water storage tank is fixedly installed between the wave water storage tanks on both sides; both ends of the U-shaped water storage tank are fixedly connected to the wave water storage tank; the U-shaped water storage tank is used to further increase the total amount of water storage while fully collecting water from waves flowing in multiple directions.

[0011] As a preferred technical solution of the present invention, the U-shaped water storage tank adopts a plurality of parallel structure designs, and a plurality of discharge ports are arranged on the U-shaped water storage tank; the plurality of discharge ports are fixedly connected with the wave water storage tank and the water storage tank respectively.

[0012] As a preferred technical solution of the present invention, a plurality of return water blocks are evenly arranged on the bottom wall of the U-shaped water storage tank; and the arrangement heights of the plurality of return water blocks decrease successively from the middle to the outside; in order to prevent the water accumulated in the water storage tank from flowing back into the U-shaped water storage tank when the amount of water in the waves collected by the U-shaped water storage tank is small, the return water blocks can make the U-shaped water storage tank only provide more water for the water storage tank, but cannot absorb the water in the water storage tank.

[0013] As a preferred technical solution of the present invention, the water-cooling channels are evenly arrayed on the heat-conducting plate on the back of the photovoltaic panel; a guide groove is arranged between the outer sides of each two adjacent water-cooling channels.

[0014] As a preferred technical solution of the present invention, a floating and sinking slow plate is fixedly installed between the guide groove on the back of the photovoltaic panel and the floating component; the floating and sinking slow plate not only reduces the degree of fluctuation caused by waves on the photovoltaic panel, but also stirs the water at the back of the photovoltaic panel to a certain extent during the fluctuation, thereby stirring the water with higher temperature with the surrounding deeper or side water, so as to achieve the effect of improving the heat dissipation effect.

[0015] As a preferred technical solution of the present invention, the floating and sinking slow plate is evenly arrayed with floating and sinking impact holes; the function of the sinking impact holes is to form a short columnar water flow during the ups and downs to stir the water at the back of the photovoltaic panel, thereby improving the stirring effect and heat dissipation effect.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention can utilize the waves of large water surfaces to provide excellent heat dissipation effect for water-floating photovoltaic modules through the functions of photovoltaic panels, floating modules and heat dissipation channels, that is, continuously provide new cooling water flow to the photovoltaic modules to maximize their water cooling effect, thereby significantly improving the heat dissipation efficiency of water-surface photovoltaic modules. It has the advantages of providing significant heat dissipation efficiency for photovoltaic modules and ensuring that they fully utilize sufficient light resources and generate maximum power generation efficiency.

[0019] 2. The present invention has the advantages of increasing the total amount of water storage and retaining sufficient wave interval redundancy, and fully collecting water for waves flowing in multiple directions through the functions of the water storage tank and the U-shaped water storage tank.

[0020] 3.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See also Figure 1-4 As shown, the present invention is a heat dissipation photovoltaic panel for a water surface wave floating photovoltaic assembly, comprising a photovoltaic panel 1, a floating assembly 2 and a heat dissipation channel 3; a photovoltaic cell 101 is fixedly installed inside the photovoltaic panel 1; a heat conducting plate 102 is sealedly installed on the back of the photovoltaic panel 1, and the bottom surface of the heat conducting plate 102 is fixedly connected to the heat dissipation channel 3 for collecting and storing water by utilizing water surface waves; a support frame 103 and a floating assembly 2 are also fixedly installed on the back frame of the photovoltaic panel 1, and the floating assembly 2 increases the required buoyancy for the photovoltaic panel 1; the heat dissipation channel 3 includes a wave water storage tank 301, a water cooling channel 302 and a drain outlet 303; wave water storage tanks 301 for increasing the water level of the stored water are fixedly installed at both ends of the water-cooling channel 302, and a drain outlet 303 with a water level difference is arranged in the middle of the water-cooling channel 302; when surface waves flow through, the waves will pass over the outer frame of the wave water storage tank 301 and enter its interior, thereby achieving the effect of accumulating water volume and water level; thereby preventing the water flow inside the wave water storage tank 301 from flowing into the water-cooling channel 302 and then flowing out from the drain outlet 303; providing a relatively sufficient water-cooling flow effect for the photovoltaic panel 1; thereby significantly improving the heat dissipation efficiency.

[0037] Among them Figure 1As shown, the outer side of the wave water storage tank 301 is provided with an arc surface 304 which is conducive to the impact of surface waves and the flow in; baffles 305 are fixed at both ends of the wave water storage tank 301; it is conducive to allowing more water in the waves to flow in; the outer side of the wave water storage tank 301 is also evenly arrayed with two water storage tanks 306 for increasing the total amount of water storage; connecting channels 307 are provided between the two water storage tanks 306 and the wave water storage tank 301; the water storage tank 306 is used to increase the total amount of water storage and retain a relatively sufficient wave interval redundancy.

[0038] The heat dissipation channel 3 of this embodiment uses the abundant water resources and relatively abundant waves of a large water surface to continuously provide sufficient water flow for the heat dissipation channel 3 to ensure that the heat dissipation effect reaches the best efficiency; the water storage tank 306 accumulates the amount of water required for the cooling water during the wave interval; and the bottom of the water storage tank 306 is not lower than the water-cooling channel 302, so that the cooling water in the water storage tank 306 can all flow out using the water level height difference; at the same time, the water level inside the water storage tank 306 is the water level of the wave crest when the wave is generated, which also makes the water level inside the water storage tank 306 higher than the water level of the water surface, ensuring the smooth flow effect of the cooling water in the heat dissipation channel 3. At the same time, when the waves flow, the undulating effect caused to the photovoltaic components will also provide the water-cooling channel 302 with flow potential energy; this embodiment is mainly suitable for large lakes with relatively abundant wind resources and waves.

[0039] Embodiment 2

In order to ensure the water storage effect of the wave water storage tank 301 and the heat dissipation effect of the heat dissipation channel 3, it is necessary to design a function that can collect waves flowing in multiple directions; therefore, a U-shaped water storage tank 308 is also fixedly installed between the wave water storage tanks 301 on both sides; both ends of the U-shaped water storage tank 308 are fixedly connected to the wave water storage tank 301; the U-shaped water storage tank 308 is used to further increase the total amount of water storage while fully collecting the water for waves flowing in multiple directions; the U-shaped water storage tank 308 adopts a plurality of parallel structure designs, and three discharge ports 309 are arranged on the U-shaped water storage tank 308; the three discharge ports 309 are fixedly connected to the wave water storage tank 301 and the water storage tank 306, respectively.

[0041] Among them Figure 6As shown, six return water blocks 310 are evenly arranged on the bottom wall of the U-shaped water storage tank 308; and the arrangement height of the six return water blocks 310 decreases from the middle to the outside; in order to prevent the water accumulated in the water storage tank 306 from flowing back into the U-shaped water storage tank 308 when the amount of water in the waves collected by the U-shaped water storage tank 308 is small, the return water blocks 310 can make the U-shaped water storage tank 308 only provide more water for the water storage tank 306, but cannot absorb the water in the water storage tank 306.

[0042] Embodiment 3

[0043] A more preferred technical solution based on the first embodiment is as follows: Figure 7-9 As shown, the water-cooling channels 302 are evenly arrayed on the heat-conducting plate 102 on the back of the photovoltaic panel 1; a guide groove 4 is arranged between the outer sides of each two adjacent water-cooling channels 302; a floating and sinking slow plate 5 is also fixedly installed between the guide groove 4 on the back of the photovoltaic panel 1 and the floating component 2; the floating and sinking slow plate 5 is not only used to reduce the degree of fluctuation caused by waves on the photovoltaic panel 1, but also to stir the water at the back of the photovoltaic panel 1 to a certain extent during the fluctuation, thereby stirring the water with higher temperature with the surrounding deeper or side water, so as to achieve the effect of improving the heat dissipation effect.

[0044] Among them Figure 7 As shown, there are floating and sinking impact holes 501 arranged evenly in an array on the floating and sinking slow plate 5; the function of the sinking impact holes 501 is to form a short columnar water flow during the ups and downs to stir the water at the back of the photovoltaic panel 1, thereby improving the stirring effect and the heat dissipation effect.

[0045] Among them Figure 8-9 As shown, a through groove 503 is opened on the floating and sinking slow plate 5, and a lateral guide plate 502 is fixed on one side of the through groove 503 of the floating and sinking slow plate 5; the directions of the eight rows of lateral guide pipes 502 are in the same direction or in the opposite direction; the lateral guide plate 502 is used to further improve the stirring effect and the heat dissipation effect.
