DETAILED DESCRIPTION

[0049] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0050] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0052] In the description of the embodiments of the present application, “plurality” means two or more than two, unless otherwise precisely and specifically specified.

[0053] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0054] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0055] As mentioned in the background art, in the related art, the energy of waste heat generated by photovoltaic panels is wasted, and the fish pond requires additional energy to heat the water, resulting in a waste of resources and an increase in costs.

[0056] In the photovoltaic power generation industry, since photovoltaic panels are electronic devices with a certain internal resistance, some waste heat will be generated when the photovoltaic panels generate electricity, which will react to the photovoltaic panel production capacity and reduce the photoelectric conversion efficiency. At the same time, the waste heat generated by photovoltaic panels when generating electricity will accelerate the aging of photovoltaic panel components or other electronic devices, further reducing the photoelectric conversion efficiency. In fisheries, appropriately increasing the water temperature of fish ponds can increase the appetite and activity enthusiasm of fish, and promote the spawning rate and survival rate of fish.

[0057] In the prior art, photovoltaic panels are cooled by air or directly exchange heat with air by convection to remove the waste heat generated by the photovoltaic panel components to reduce the negative impact of heat energy on the production capacity of photovoltaic panels. Compared with fluid cooling, the effect is poor. There are also methods of fluid heat exchange in related technologies, such as using organic substances such as ethylene glycol and oil for heat exchange, but the cost is high, the requirements for equipment are strict, and the cost is high. In addition, the fluid needs to be cooled twice.

[0058] Fish ponds heat the water by adding heaters to achieve a suitable water temperature for fish growth.

[0059] Based on the above technical problems, an embodiment of the present application provides a photovoltaic panel heat dissipation device. In this technical solution, a heat exchange component is arranged on the backlight surface of the photovoltaic panel assembly, and a water pump is used to draw water from the fish pond into the heat exchange component through the water inlet. The water in the heat exchange component will be heated by the waste heat of the photovoltaic panel assembly and then flow back into the fish pond through the water outlet. In the above process, on the one hand, the water in the fish pond can absorb the waste heat generated by the photovoltaic panel assembly. Compared with traditional convection heat exchange, the heat dissipation efficiency of the photovoltaic panel assembly can be improved, thereby improving the photoelectric conversion efficiency of the photovoltaic panel assembly; on the other hand, the water heated by the waste heat of the photovoltaic panel assembly flows back into the fish pond, which can heat the water in the fish pond and increase the temperature of the water in the fish pond, thereby promoting the spawning rate and survival rate of fish; the complementarity between the photovoltaic power generation industry and the fishery industry is realized, and the resource utilization rate is improved.

[0060] It should be noted that Figures 1 to 9 The schematic diagram of each component in the photovoltaic panel heat dissipation device is shown. The specific structure of the remaining components in the photovoltaic panel heat dissipation device is not limited to Figures 1 to 9 of examples.

[0061] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0062] Reference Figure 1 and Figure 2 As shown, a photovoltaic panel heat dissipation device provided in an embodiment of the present application is used for a photovoltaic panel assembly 100 , including a water pump 200 and a heat exchange assembly 300 .

[0063] The heat exchange component 300 is used to be arranged on the backlight surface of the photovoltaic panel component 100 . The heat exchange component 300 has a water inlet 301 and a water outlet 302 connected to the water inlet 301 .

[0064] The water pump 200 is configured to connect the fish pond and the water inlet 301 to pump the water in the fish pond into the heat exchange assembly 300 through the water inlet 301 so that the water in the heat exchange assembly 300 is heated by the waste heat of the photovoltaic panel assembly 100 .

[0065] The water outlet 302 is used to communicate with the fish pond.

[0066] In the above-mentioned embodiment, it should be noted that the photovoltaic panel assembly 100 is a mature technology in the relevant field, and the specific structure of the photovoltaic panel assembly 100 is not overly restricted in the embodiment of the present application. The photovoltaic panel assembly 100 has a relative light-absorbing surface and a backlight surface, and the light-absorbing surface is used to be set toward the light for photoelectric conversion.

[0067] In the related art, the photovoltaic panel assembly 100 generates waste heat during the power generation process. By setting a heat exchange assembly 300 on the backlight surface of the photovoltaic panel assembly 100, the water in the fish pond is sucked into the heat exchange assembly 300 through the water inlet 301 by using a water pump 200. The water in the heat exchange assembly 300 is heated by the waste heat of the photovoltaic panel assembly 100 and then flows back into the fish pond through the water outlet 302. In the above process, on the one hand, the water in the fish pond can absorb the waste heat generated by the photovoltaic panel assembly 100. Compared with traditional convection heat exchange, the heat dissipation efficiency of the photovoltaic panel assembly 100 can be improved, thereby improving the photoelectric conversion efficiency of the photovoltaic panel assembly 100; on the other hand, the water heated by the waste heat of the photovoltaic panel assembly 100 flows back into the fish pond, which can heat the water in the fish pond and increase the temperature of the water in the fish pond, thereby promoting the spawning rate and survival rate of fish; the photovoltaic power generation industry and the fishery industry complement each other, and the resource utilization rate is improved. The fish pond does not need to set up a heater to heat the water, thereby reducing costs.

[0068] In one possible implementation, refer to Figure 1 , Figure 2 and Figure 3 As shown, the heat exchange assembly 300 includes a heat exchange plate 310, which is used to abut against the backlight surface of the photovoltaic panel assembly 100. A water storage chamber 311 is opened in the heat exchange plate 310, and the water inlet 301 and the water outlet 302 are both connected to the water storage chamber 311.

[0069] In the above embodiment, by setting the heat exchange plate 310, it is possible to achieve a larger area of ​​abutment with the photovoltaic panel assembly 100, thereby increasing the contact area between the photovoltaic panel assembly 100 and the heat exchange plate 310, thereby improving the heat conduction efficiency between the photovoltaic panel assembly 100 and the heat exchange plate 310, and further improving the heat dissipation efficiency of the photovoltaic panel assembly 100.

[0070] Furthermore, a plurality of shallow grooves are provided on the side of the heat exchange plate 310 facing away from the photovoltaic panel assembly 100 , which can further improve the heat conduction efficiency.

[0071] In one possible implementation, continue to refer to Figure 2 As shown, Figure 2 The arrows shown in the figure are the flow direction of water in the heat exchange assembly 300. In order to further improve the heat dissipation efficiency, the water inlet 301 is located at the bottom of the water storage chamber 311, the water outlet 302 is located at the top of the water storage chamber 311, and the water inlet 301 and the water outlet 302 are respectively arranged at the diagonal positions of the heat exchange plate 310, so that the water entering the water storage chamber 311 from the water inlet 301 needs to first fill the water storage chamber 311 completely, and then flow out from the water outlet 302, which can ensure that the water in the water storage chamber 311 is fully heated, thereby improving the heat dissipation efficiency of the photovoltaic panel assembly 100 and the heating efficiency of the water in the water storage chamber 311.

[0072] In one possible implementation, refer to Figure 2 , Figure 3 and Figure 4 As shown, the heat exchange plate 310 includes a first heat exchange plate 312 , a second heat exchange plate 313 and a first sealing member 314 .

[0073] The first heat exchange plate 312 and the second heat exchange plate 313 are arranged opposite to each other and jointly enclose a water storage chamber 311. One of the first heat exchange plate 312 and the second heat exchange plate 313 is used to abut against the backlight surface of the photovoltaic panel assembly 100. The first seal 314 is arranged between the first heat exchange plate 312 and the second heat exchange plate 313 to seal the water storage chamber 311.

[0074] Specifically, the first sealing member 314 may be a sealing strip, which is disposed at the side edge between the first heat exchange plate 312 and the second heat exchange plate 313. The specific structure of the first sealing member 314 is not limited in the embodiment of the present application.

[0075] In the above embodiment, the first heat exchange plate 312 and the second heat exchange plate 313 are arranged opposite to each other and are jointly arranged to form a water storage chamber 311. In this way, the water storage chamber 311 can be easily cleaned. The first heat exchange plate 312 and the second heat exchange plate 313 only need to be separated to expose the water storage chamber 311. It can be understood that because the flowing water in the water storage chamber 311 is water from a river or a lake, it contains more microorganisms or impurities, which can easily cause scale, moss, etc. to accumulate on the inner wall of the water storage chamber 311. The above arrangement can facilitate the cleaning of the water storage chamber 311 and prevent the water storage chamber 311 from being blocked. The first sealing member 314 can improve the sealing performance of the water storage chamber 311 to prevent water leakage.

[0076] Continue to refer to Figure 3 , Figure 4 and Figure 5 As shown, two blocking members 315 are also included; the blocking member 315 has a connecting cavity 3151 therein, and the connecting cavities 3151 of the two blocking members 315 are respectively connected to the two ends of the water storage cavity 311; and the connecting cavities 3151 of the two blocking members 315 are respectively connected to the water inlet 301 and the water outlet 302.

[0077] Here, the water storage chamber 311 can be a cylindrical hole or a square hole. Of course, the number of water storage chambers 311 can be multiple, and multiple water storage chambers 311 are arranged at intervals to improve the heat dissipation effect. The two ends of the multiple water storage chambers 311 are respectively connected to the connecting chamber 3151 of the corresponding sealing member 315. It can be understood that the connecting chamber 3151 can collect water in multiple water storage chambers 311 to improve the circulation efficiency.

[0078] In order to further improve the sealing performance, the ends of the first heat exchange plate 312 and the second heat exchange plate 313 facing the sealing member 315 are located in the connecting cavity 3151. In this way, the sealing member 315 is equivalent to being sleeved on the ends of the first heat exchange plate 312 and the second heat exchange plate 313, thereby improving the sealing performance between the first heat exchange plate 312 and the second heat exchange plate 313.

[0079] Furthermore, the blocking member 315 is sleeved on the ends of the first heat exchange plate 312 and the second heat exchange plate 313 , which is equivalent to making the first heat exchange plate 312 and the second heat exchange plate 313 detachably connected, thereby facilitating the installation and cleaning of the water storage chamber 311 .

[0080] Please continue to refer to Figure 5 As shown, in a possible implementation manner, in order to facilitate the disassembly of the first heat exchange plate 312 and the second heat exchange plate 313 , at least one connecting member 316 is further included.

[0081] The connecting member 316 includes a connecting stud 3161 , a first clamping plate 3162 , a second clamping plate 3163 , a first connecting nut 3164 and a second connecting nut 3165 .

[0082] The first clamping plate 3162 is connected to the end of the connecting stud 3161, and the second clamping plate 3163 is slidingly connected to the connecting stud 3161; the first connecting nut 3164 and the second connecting nut 3165 are both threadedly connected to the connecting stud 3161, and the second clamping plate 3163 is located between the first clamping plate 3162 and the first connecting nut 3164; the first connecting nut 3164 is located between the second clamping plate 3163 and the second connecting nut 3165.

[0083] The first clamping plate 3162 and the second clamping plate 3163 are used to clamp the heat exchange plate 310 .

[0084] The first connecting nut 3164 and the second connecting nut 3165 are used to clamp the photovoltaic panel assembly 100 .

[0085] In this way, the first connecting nut 3164 can be operated to move the second clamping plate 3163 toward the first clamping plate 3162, so that the first clamping plate 3162 and the second clamping plate 3163 clamp the first heat exchange plate 312 and the second heat exchange plate 313. At the same time, the second connecting nut 3165 can be operated to clamp the first connecting nut 3164 and the second connecting nut 3165 to clamp the frame on the photovoltaic panel assembly 100. Through the above-mentioned setting method, on the one hand, the first heat exchange plate 312 and the second heat exchange plate 313 can be detachably connected, and on the other hand, the connection between the heat exchange plate 310 and the photovoltaic panel assembly 100 can be facilitated. For the modification project of the photovoltaic panel assembly 100 in the prior art, the heat exchange plate 310 can be installed on the basis of the original photovoltaic panel assembly 100, thereby improving the heat dissipation efficiency of the photovoltaic panel assembly 100 and improving resource utilization.

[0086] One of the first heat exchange plate 312 and the second heat exchange plate 313 needs to abut against the backlight surface of the photovoltaic panel assembly 100. In order not to affect the abutment between the two, an avoidance groove 3101 is dug at the position of the heat exchange plate 310 corresponding to the first clamping plate 3162 and the second clamping plate 3163, and the first clamping plate 3162 and the second clamping plate 3163 are respectively located in the corresponding avoidance groove 3101. The avoidance groove 3101 is opened at the corresponding position of the first heat exchange plate 312 and the second heat exchange plate 313. In this way, by setting the avoidance groove 3101, the abutment between the first heat exchange plate 312 and the second heat exchange plate 313 and the photovoltaic panel assembly 100 is not interfered, and the heat dissipation efficiency is not affected.

[0087] In one possible implementation, refer to Figure 7 Combined with Figure 2 As shown, it also includes a second seal 320, which is used to be arranged between the heat exchange plate 310 and the photovoltaic panel assembly 100 to seal the gap between the heat exchange plate 310 and the photovoltaic panel assembly 100. It can be understood that the fish pond can be an indoor fish pond or an outdoor fish pond. When the above-mentioned photovoltaic panel heat dissipation device is used in an outdoor fish pond, in order to shorten the materials used for various pipelines and circuits, the above-mentioned photovoltaic panel heat dissipation device can be arranged outdoors together with the photovoltaic panel assembly 100. The second seal 320 is arranged between the photovoltaic panel assembly 100 and the heat exchange plate 310, which can prevent the gap between the photovoltaic panel assembly 100 and the heat exchange plate 310 from entering dust or rain and snow, and can improve the safety and stability of the photovoltaic panel assembly 100 and the heat exchange plate 310, and improve the service life of the photovoltaic panel assembly 100 and the heat exchange plate 310. In specific implementation, the second seal 320 can be a rubber seal ring or a sealing silicone. The embodiment of the present application does not limit the specific material of the second seal 320.

[0088] In one possible implementation, refer to Figure 1 and Figure 7 As shown, Figure 7 The arrows shown in are the flow direction of water in the heat exchange component 300 . The heat exchange component 300 includes a plurality of fins 330 and a heat exchange tube 340 .

[0089] The fins 330 are arranged at intervals on the backlight surface of the photovoltaic panel assembly 100. The heat exchange tube 340 is coiled between the multiple fins 330. The two ends of the heat exchange tube 340 are respectively a water inlet 301 and a water outlet 302. Specifically, the heat exchange tube 340 is coiled in a serpentine shape.

[0090] In the above embodiment, the fin 330 is a basic heat transfer element, which can expand the heat exchange area and improve the efficiency of heat conduction. The fin 330 forms a strong turbulence in the flow channel, and breaks and reorganizes the flow boundary layer and the thermal boundary layer, thereby enhancing heat exchange; the fin 330 can also improve the overall strength of the photovoltaic panel assembly 100.

[0091] The serpentine-shaped heat exchange tube 340 can expand the contact area between the heat exchange tube 340 and the fin 330, enhance the heat exchange efficiency between the water in the heat exchange tube 340 and the fin 330, and by adopting a serpentine design, a longer heat exchange tube 340 can be provided in a limited space, thereby increasing the heat exchange area, increasing the water storage capacity in the heat exchange tube 340, and improving the heat exchange efficiency.

[0092] In one possible implementation, refer to Figure 1 and Figure 8 As shown, a filter element 400 is also included.

[0093] The filter element 400 is connected to the water pump 200 to filter the water of the fish pond entering the water pump 200 .

[0094] In the above embodiment, the filter element 400 can be a filter, filter net, etc. in the relevant field, which can physically filter the water entering the water pump 200 to prevent clogging of the water pump 200. Of course, the filter element 400 can also be a filter cotton core with a purification function, which can effectively absorb bacteria or microorganisms in the water, making the water in the water pump 200 or the water in the heat exchange component 300 cleaner, improving the safety of the water pump 200 or the heat exchange component 300, and extending the service life of the water pump 200 or the heat exchange component 300.

[0095] In one possible implementation, continue to refer to Figure 1 and Figure 8 As shown, it also includes an energy storage component 500 , a control component 600 and a heating component 700 .

[0096] The control component 600 is used to be electrically connected to the photovoltaic panel assembly 100 , the energy storage component 500 is electrically connected to the control component 600 , and the heating component 700 is electrically connected to the control component 600 .

[0097] The control element 600 is configured to control the photovoltaic panel assembly 100 to start and stop the charging process of the energy storage element 500, and to control the energy storage element 500 and / or the photovoltaic panel assembly 100 to start and stop the power supply process of the heating element 700.

[0098] The heating element 700 is used to be inserted into a fish pond and heat the water in the fish pond.

[0099] In the above embodiments, it can be understood that the photovoltaic panel assembly 100 can convert light energy into electrical energy. By providing an energy storage component 500, the electrical energy generated by the photovoltaic panel assembly 100 can be stored in the energy storage component 500. In the relevant field, the energy storage component 500 can be a battery, or of course a power grid. It only needs to be able to store the electrical energy generated by the photovoltaic panel assembly 100. The embodiments of the present application do not impose too many restrictions on the specific structure of the energy storage component 500.

[0100] In specific implementation, for example, when the outdoor light is strong, the control component 600 can control the photovoltaic panel assembly 100 to start the charging process of the energy storage component 500, and the electric energy generated by the photovoltaic panel assembly 100 is stored in the energy storage component 500. According to the needs of the on-site environment, the control component 600 can also control the photovoltaic panel assembly 100 to power the heating component 700, and the heating component 700 is powered to generate heat to heat the water in the fish pond. Alternatively, when the light intensity is weakened or at night, the control component 600 can also control the energy storage component 500 to power the heating component 700 so that the heating component 700 generates heat to maintain a suitable water temperature in the fish pond. In the above, the photovoltaic panel assembly 100 can power at least one of the energy storage component 500 and the heating component 700, and the charging of the energy storage component 500 and the heating of the heating component 700 can be realized at the same time, which has the effect of improving the utilization rate of the energy storage component 500, and can also maintain the water temperature of the water in the fish pond within a suitable temperature range for a long time. Further improve resource utilization.

[0101] In a possible implementation, a detection component (not shown in the drawings) is also included.

[0102] The detection component is used to detect the water temperature of the fish pond, and the detection component is electrically connected to the control component 600.

[0103] The control element 600 is configured to control the energy storage element 500 and / or the photovoltaic panel assembly 100 to start the power supply process of the heating element 700 when the water temperature of the fish pond is lower than the first preset temperature; and to control the energy storage element 500 and / or the photovoltaic panel assembly 100 to close the power supply process of the heating element 700 when the water temperature of the fish pond is higher than the second preset temperature. The first preset temperature is lower than the second preset temperature.

[0104] The detection element may be a temperature sensor.

[0105] When the water temperature of the fish pond is lower than the first preset temperature, the control component 600 controls the energy storage component 500 and / or the photovoltaic panel assembly 100 to supply power to the heating component 700, and the heating component 700 generates heat to heat the water in the fish pond. When the water temperature of the fish pond is higher than the second preset temperature, the control component 600 controls the energy storage component 500 and / or the photovoltaic panel assembly 100 to turn off the power supply process of the heating component 700, so as to maintain the water temperature in the fish pond within a suitable temperature range and improve the activity of the fish.

[0106] Of course, the first preset temperature and the second preset temperature in the above process need to be selected and set according to the actual application scenario, and it is necessary to consider making appropriate choices for different types of fish. The embodiment of the present application does not impose too many restrictions on this.

[0107] In one possible implementation, refer to Figure 8 As shown, the control component 600 includes a main controller 610 and a discharge controller 620 electrically connected to the main controller 610. The main controller 610 is electrically connected to the photovoltaic panel assembly 100 and to the energy storage component 500. The discharge controller 620 is electrically connected between the main controller 610 and the heater. The detection component is electrically connected to the discharge controller 620, and the discharge controller 620 can control the on-off of the circuit between the main controller 610 and the heater, which is equivalent to adding a circuit protection device between the main controller 610 and the heater to prevent the heater from overheating or the heater from heating the fish pond water for a long time.

[0108] In one possible implementation, refer to Figure 1 , Figure 8 and Fig. 9 As shown, the heating element 700 includes an electric heating rod 710 and a protective net 720 .

[0109] The electric heating rod 710 is electrically connected to the control unit 600 , and the protective net 720 is wrapped around the outer circumference of the electric heating rod 710 .

[0110] The electric heating rod 710 has a simple structure, which helps to reduce the production cost. The electric heating rod 710 generates heat when it is powered on, thereby heating the water in the fish pond. The protective net 720 is coated on the outer peripheral side of the electric heating rod 710, which is equivalent to coating the electric heating rod 710 with a protective layer. It can be understood that there are fish or other plants in the fish pond. The protective net 720 is arranged on the outer peripheral side of the electric heating rod 710 to protect the electric heating rod 710 from being damaged by the fish or other plants. Of course, the protective net 720 can also prevent the fish from directly contacting the electric heating rod 710 and causing damage to the fish.

[0111] Furthermore, the protective net 720 has an insulating rubber layer, which can prevent the electric heating rod 710 from short-circuiting, thereby improving the safety of the electric heating rod 710.

[0112] The implementation principle of a photovoltaic panel heat dissipation device in an embodiment of the present application is as follows: a photovoltaic panel heat dissipation device, used for a photovoltaic panel assembly 100, includes a water pump 200 and a heat exchange assembly 300. The heat exchange assembly 300 is used to be arranged on the backlight surface of the photovoltaic panel assembly 100, and the heat exchange assembly 300 has a water inlet 301 and a water outlet 302 connected to the water inlet 301. The water pump 200 is configured to connect the fish pond and the water inlet 301, so as to draw the water of the fish pond into the heat exchange assembly 300 through the water inlet 301, and after being heated by the residual heat of the photovoltaic panel assembly 100, the water flows into the fish pond through the water outlet 302. By arranging the heat exchange assembly 300 on the backlight surface of the photovoltaic panel assembly 100, the water of the fish pond is drawn into the heat exchange assembly 300 through the water inlet 301 by using the water pump 200, and the water in the heat exchange assembly 300 is heated by the residual heat of the photovoltaic panel assembly 100 and flows back into the heat exchange assembly 300 through the water outlet 302. In the fish pond, during the above process, on the one hand, the water in the fish pond can absorb the waste heat generated by the photovoltaic panel assembly 100, which can improve the heat dissipation efficiency of the photovoltaic panel assembly 100 compared with traditional convection heat exchange, thereby improving the photoelectric conversion efficiency of the photovoltaic panel assembly 100; on the other hand, the water heated by the waste heat of the photovoltaic panel assembly 100 flows back into the fish pond, which can heat the water in the fish pond and increase the temperature of the water in the fish pond, thereby promoting the spawning rate and survival rate of fish; realizing the complementarity of the photovoltaic power generation industry and the fishery industry, and improving resource utilization.
