Description

Technical Field

[0001] The present invention belongs to the technical field of heat dissipation of photovoltaic panels, and in particular relates to a heat dissipation device for a water photovoltaic panel and a use method thereof. Background Art

[0002] In recent years, photovoltaic power generation technology has become increasingly mature. In addition to ground photovoltaic power generation technology, my country is also exploring water photovoltaic power generation technology. Compared with building photovoltaic power stations on land, building power stations on water can obtain a wide construction space, save land resources, and prevent water resources from evaporating, which has an inhibitory effect on the growth of algae in the water. In the middle and lower reaches of the Yangtze River, rivers, lakes and reservoirs are widely distributed. The pile foundation can be used to fix the power station, that is, the pile foundation is fixed underwater, and the photovoltaic support system is installed at the end of the pile, forming an integrated development model that can generate electricity above and raise fish below.

[0003] Studies have shown that when the temperature of photovoltaic panels exceeds 10°C, the output power of photovoltaic conversion decreases by about 0.4% for every 1°C increase in the temperature of the photovoltaic panels. When the temperature is too high, the aging rate of the photovoltaic panels will be accelerated. Therefore, it is necessary to use efficient heat dissipation technology to cool the photovoltaic panels, such as phase change materials and heat pipes. Considering the cooling cost, natural wind cooling is generally used, which is not economical and increases the coastal environment temperature. Summary of the invention

[0004] In view of this, the present invention provides a heat dissipation device for water photovoltaic panels and a method of use to solve the problem of using natural wind to cool photovoltaic panels in the prior art, which is not only uneconomical but also increases the coastal environmental temperature.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A heat dissipation device for a water-based photovoltaic panel, comprising a foundation pile and a photovoltaic panel arranged above the foundation pile;

[0007] A cavity is provided inside the side wall of the foundation pile;

[0008] A packaging shell is provided at the bottom of the photovoltaic panel, and a plurality of heat pipes are provided in the packaging shell. One end of the heat pipe passes through the packaging shell to be connected to a header. A dielectric liquid is contained in the header. The two ends of the header are respectively connected to a first loop pipe and a second loop pipe. The ends of the first loop pipe and the second loop pipe away from the header are respectively connected to the cavity of the foundation pile, and a geothermal source pump is provided on the first loop pipe.

[0009] In this technical solution, it should be noted that there are multiple foundation piles, and the cavities of two adjacent foundation piles are connected by a connecting pipe. Both ends of the heat pipe are closed structures, and heat is transferred between the heat pipe and the medium liquid in the header through the contact between the walls. In this solution, in the non-heating season, the photovoltaic panel absorbs the heat of the sun and transfers the temperature to the packaging shell on the back. The packaging shell transfers the heat to the heat pipe, and the heat pipe transfers the heat to the medium liquid in the header through the wall heat exchange method. The medium liquid circulates in the header, the first loop pipe, the cavity and the second loop pipe under the action of the ground heat source pump, and transfers the heat to the surrounding soil through the cavity during the flow process; in summary, the present invention can realize the cooling of the photovoltaic panel through the heat pipe, header, first loop pipe, second loop pipe and cavity, and can transfer the heat of the photovoltaic panel to the surrounding soil for storage, and extract it in the winter heating season to achieve cross-season heat storage; and because the fixed power station with pile foundation on water needs to drive more piles, the cost is high and the construction is not easy, so the cavity can be set in the foundation pile to form an energy pile to reduce the construction cost.

[0010] Preferably, a lifting cylinder is sleeved on the foundation pile, the photovoltaic panel is fixedly connected to the lifting cylinder through a bracket, a buoy is fixedly sleeved on the side wall of the lifting cylinder, and the first loop pipe and the second loop pipe are both hoses.

[0011] In this technical solution, it should be noted that lakes may generally experience rising water levels. If the water level rises too much, the photovoltaic panels may be submerged, causing damage to the photovoltaic panels due to immersion. Based on this, the present invention is provided with a float and a lifting cylinder. The float can adaptively drive the lifting cylinder and the photovoltaic panel to rise and fall through the rise and fall of the lake liquid level, and the photovoltaic panels will not be submerged. The first loop pipe and the second loop pipe are both retractable hoses that can extend or shorten as the photovoltaic panels rise and fall.

[0012] Preferably, the packaging shell is filled with a phase change material, and the phase change material wraps the heat pipe.

[0013] In this technical solution, it should be noted that the phase change material is set to maintain the temperature of the photovoltaic panel in a suitable range and ensure that the temperature of the back panel is uniform.

[0014] Preferably, the second loop pipe is connected to a heat conducting pipe, and a first valve for opening and closing the second loop pipe and the heat conducting pipe is provided at the connection point between the heat conducting pipe and the second loop pipe.

[0015] Preferably, a heat transfer pipe is provided on one side of the foundation pile, one end of the heat transfer pipe is connected to the first loop pipe, and the other end is connected to the second loop pipe, and a second valve for opening and closing the first loop pipe and the heat transfer pipe is provided at the connection point between the heat transfer pipe and the first loop pipe, and a third valve for opening and closing the second loop pipe and the heat transfer pipe is provided at the connection point between the heat transfer pipe and the second loop pipe.

[0016] In this technical solution, it should be noted that in the non-heating season, the heat transfer pipe is closed by the first valve, one end of the second loop pipe is opened, one end of the heat transfer pipe is closed by the third valve, the other end of the second loop pipe is opened, the other end of the heat transfer pipe is closed by the second valve, and the first loop pipe is opened; the photovoltaic panel absorbs the heat of the sun and transfers the temperature to the packaging shell on the back, the packaging shell transfers the heat to the heat pipe through the phase change material, the heat pipe transfers the heat to the medium liquid in the manifold by the partition heat exchange method, the medium liquid circulates in the manifold, the first loop pipe, the cavity and the second loop pipe under the action of the geothermal source pump, and transfers the heat to the surrounding soil through the cavity during the flow;

[0017] In the season when heating is needed, the heat transfer pipe is opened through the first valve, one end of the second loop pipe is closed, the other end of the second loop pipe is opened through the third valve, one end of the heat transfer pipe is sealed, and the first loop pipe is closed through the second valve; after absorbing the heat from the surrounding soil, the medium liquid in the cavity is collected from the heat transfer pipe into the building heating network through the pressure of the geothermal source pump for residents to use; after releasing heat, the medium liquid passes through the external pipeline and then enters the cavity of the pile foundation.

[0018] Preferably, a water pump is provided on one side of the heat transfer tube.

[0019] In this technical solution, it should be noted that a water pump is provided to increase the fluidity of the surrounding water source and improve the heat exchange effect.

[0020] Preferably, a scraping strip is slidably connected to the surface of the photovoltaic panel, one end of the scraping strip is rotatably connected to the header via a rotating shaft, the rotating shaft is vertically arranged, and the header is also provided with a driving device for driving the rotating shaft to rotate. One end of the rotating shaft penetrates into the header, and the driving device includes a fan blade, which is arranged on the rotating shaft along the radial direction of the rotating shaft, and the fan blade is located in the header.

[0021] In this technical solution, it should be noted that after the solar panels are used for a long time, the dust in the air and the droppings of flying birds will stick to the surface of the photovoltaic panels, and the adhesion of these impurities will block the incidence of sunlight, reduce the light absorption capacity of the photovoltaic components, and thus lead to a decrease in power generation efficiency. Based on this, a scraper bar and a drive device are provided in this solution. When the medium liquid passes through the linkage box, the medium liquid will impact the fan blades, so that the fan blades can rotate under the drive of the medium liquid. After the fan blades rotate, the rotating shaft is driven to rotate, and then the scraper bar on the rotating shaft is driven to rotate. During the rotation of the scraper bar, the dust on the surface of the photovoltaic panel is swept out, thereby improving the power generation efficiency of the photovoltaic panel. Furthermore, in this solution, the length of the scraper bar is greater than the length of the diagonal of the photovoltaic panel, so that the scraper bar can cover the entire photovoltaic panel during the rotation.

[0022] Preferably, a tension spring is provided on the top of the junction box, one end of the tension spring is connected to the plaster scraping strip, and the other end is connected to the junction box.

[0023] In this technical solution, it should be noted that a tension spring is provided to assist the fan blades in the coupling box to reset themselves. That is, when the fan blades in the coupling box rotate and move by an angle under the power of the dielectric liquid, when the dielectric liquid separates from the fan blades, the fan blades return to their initial positions under the action of an external pull ring.

[0024] A method for using a heat dissipation device for a water-based photovoltaic panel, comprising:

[0026] The photovoltaic panel absorbs the heat from the sun and transfers the temperature to the packaging shell on the back. The packaging shell transfers the heat to the heat pipe through the phase change material. The heat pipe transfers the heat to the medium liquid in the header through the partition heat exchange method. The medium liquid circulates in the header, the first loop pipe, the cavity and the second loop pipe under the action of the geothermal source pump. During the flow, the heat is transferred to the surrounding soil through the cavity.

[0028] After absorbing the heat from the surrounding soil, the medium liquid in the cavity is fed into the building heat network through the heat pipe through the pressure of the geothermal source pump for residents to use. After releasing the heat, the medium liquid passes through the external pipeline and then enters the cavity of the foundation pile.

[0029] A3: When the temperature in the pond is too low, one end of the heat transfer pipe is opened through the third valve, one end of the second loop pipe is closed, and the other end of the heat transfer pipe is opened through the second valve, and the first loop pipe is closed;

[0030] After absorbing the heat from the surrounding soil, the medium liquid in the cavity flows into the heat transfer tube through the pressure of the geothermal source pump, and exchanges heat with the water source around the heat transfer tube. At the same time, the water pump is started to improve the fluidity of the lake water and enhance the heat exchange effect.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. In the present invention, the photovoltaic panel can be cooled by the heat pipe, the header, the first loop pipe, the second loop pipe and the cavity. The heat exchange between the heat pipe and the header wall ensures the reliability of the system and facilitates the maintenance and repair of the system. At the same time, the heat of the photovoltaic panel can be transferred to the surrounding soil for storage and extracted in the winter heating season to achieve cross-seasonal heat storage. In addition, since the water pile foundation fixed power station needs to drive more piles, the cost is high and the construction is not easy, the cavity is set in the foundation pile to form an energy pile, thereby reducing the construction cost.

[0033] 2. The present invention is provided with a buoy and a lifting cylinder. The buoy can adaptively drive the lifting cylinder and the photovoltaic panel to rise and fall by the rise and fall of the lake liquid level, and the photovoltaic panel will not be submerged;

[0034] 3. The present invention is provided with a scraper bar and a driving device. When the medium liquid passes through the linkage box, the medium liquid will impact the fan blades, thereby allowing the fan blades to rotate under the drive of the medium liquid.
