Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and specifically to a photovoltaic power generation heat conversion and utilization device. Background Technology

[0002] Photovoltaic panels, as an advanced energy conversion device, have the core function of cleverly utilizing the radiant energy of sunlight. Through the photovoltaic effect, a natural phenomenon, they directly convert the inexhaustible solar energy into directly usable direct current electricity. However, while photovoltaic panels efficiently perform their power generation mission, a phenomenon that is often overlooked is that their surface temperature also rises significantly when exposed to direct sunlight. This is because some solar radiation energy is directly absorbed or reflected as heat energy and accumulates on the panel surface. Unfortunately, many photovoltaic panel designs currently on the market often focus only on maximizing their power output efficiency, while rarely actively collecting and efficiently utilizing this accompanying heat energy resource. This means that a large amount of heat energy with potential utilization value is simply lost to the air without being properly captured and converted, becoming a neglected waste. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a photovoltaic power generation heat conversion and utilization device, which can effectively solve the problem that existing photovoltaic devices often neglect the collection of heat energy on the photovoltaic panel.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a photovoltaic power generation heat conversion and utilization device, including a photovoltaic panel. Two sets of heat-conducting pipes for collecting heat are arranged below the photovoltaic panel. The heat-conducting pipes are spirally arranged in a U-shape, and the two sets of heat-conducting pipes are intertwined. The water outlet of the heat-conducting pipes is fixedly connected to the same set of water tanks. A discharge control component for controlling the flow rate of liquid discharge in the heat-conducting pipes is arranged in the water tanks and at the water outlet of the heat-conducting pipes.

[0006] The control and discharge assembly includes a connecting pipe fixedly installed at the outlet end of the temperature guide pipe, a fixed plate fixedly installed inside the connecting pipe, a swivel pipe rotatably installed on one side of the connecting pipe, a baffle fixedly installed inside the swivel pipe, a fixed shaft fixedly installed on the swivel pipe, the baffle rotatably installed on the fixed shaft, a corrugated groove opened on the outer side of the swivel pipe, and a temperature control assembly provided on the temperature guide pipe. The temperature control assembly pushes the corrugated groove to rotate through the corrugated groove, thereby controlling the relative rotational deviation between the baffle and the opening of the fixed plate.

[0007] Furthermore, the temperature control component includes a sleeve fixedly fitted onto the temperature-conducting tube, the sleeve being filled with gas, an L-shaped tube fixed to one side of the sleeve, a sliding rod slidably inserted into the end of the L-shaped tube, a protruding rod fixedly connected to one side of the sliding rod, and the end of the protruding rod slidably inserted into the corrugated groove.

[0008] Furthermore, both the connecting pipe and the corrugated groove are rotatably fitted with support members, and the support members are fixedly connected to the top of the water tank.

[0009] Furthermore, a float plate is provided at the bottom of the sleeve, two sets of telescopic rods are fixedly connected between the sleeve and the float plate, and an adjustment knob is fixedly installed at the bottom of the sleeve.

[0010] Furthermore, a heat-conducting layer for transferring heat energy is fixedly installed at the bottom of the photovoltaic panel, and the heat-conducting layer wraps around the upper and lower sides of the heat-conducting pipe.

[0011] Furthermore, both the fixing plate and the baffle are annular three-part sector plates.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] This device, by combining temperature control components and flow control components, can monitor the temperature of the liquid inside the heat pipe in real time, accurately sense temperature changes, and intelligently adjust the flow rate of the liquid inside the heat pipe to ensure that the liquid temperature is always maintained within a safe high-temperature threshold range. Through this dynamic adjustment mechanism, not only can heat loss or safety hazards caused by excessively high liquid temperature be avoided, but heat transfer efficiency can also be significantly improved, so that the heat energy generated on the surface of the photovoltaic panel can be collected to the maximum extent and converted into usable energy.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Appendix Figure 1 —Appendix Figure 5 As shown, a photovoltaic power generation heat conversion and utilization device includes a photovoltaic panel 1. A heat-conducting layer 2 for transferring heat energy is fixedly installed on the bottom of the photovoltaic panel 1, and the heat-conducting layer 2 wraps around the upper and lower sides of a heat-conducting pipe 3. The heat-conducting layer 2 guides the heat on the photovoltaic panel 1 to the heat-conducting pipe 3, and can also isolate the moisture emitted by the heat-conducting pipe 3, thus protecting the photovoltaic panel 1. Two sets of heat-conducting pipes 3 for collecting heat are arranged below the photovoltaic panel 1. The heat-conducting pipes 3 are arranged in a spiral shape, and the two sets of heat-conducting pipes 3 are interlaced. The water inlet ends of the two sets of heat-conducting pipes 3 are... The axial symmetry, as described above, facilitates rapid and uniform heating of the liquid within the heat-conducting pipe 3. Compared to common serpentine heat-conducting pipes, the liquid flow path within the heat-conducting pipe 3 can be shortened by half. Once the liquid reaches a certain temperature, it can be quickly discharged, preventing prolonged high temperatures in certain areas of the heat-conducting pipe 3. The outlet end of the heat-conducting pipe 3 is fixedly connected to the same set of water tanks 4, and the heated liquid is all introduced into the water tanks 4. A discharge control component is installed in the water tanks 4 and located at the outlet end of the heat-conducting pipe 3 to control the discharge flow rate of the liquid within the heat-conducting pipe 3.

[0024] Specifically, the control and discharge assembly includes a connecting pipe 5 fixedly installed at the outlet end of the temperature guide pipe 3, a rotatable tube 502 rotatably installed on one side of the connecting pipe 5, and a support member 504 rotatably sleeved on both the connecting pipe 5 and the corrugated groove 503. The support member 504 is fixedly connected to the top of the water tank 4, and the support member 504 supports the connection between the connecting pipe 5 and the corrugated groove 503 and the water tank 4, thereby keeping it horizontal and fixed.

[0025] A fixed plate 501 is fixedly installed inside the connecting pipe 5, and a baffle 505 is fixedly installed inside the spiral pipe 502. Both the fixed plate 501 and the baffle 505 are annular three-part sector plates. A fixed shaft is fixedly installed on the spiral pipe 502, and the baffle 505 is rotatably installed on the fixed shaft. The discharge volume is controlled by changing the misalignment area between the baffle 505 and the spiral pipe 502 by rotating the baffle 505. When the spiral pipe 502 and the baffle 505 are completely misaligned, the outlet end of the temperature guide pipe 3 is sealed, and no liquid is discharged. When the spiral pipe 502 and the baffle 505 are completely overlapped, it is the maximum discharge volume of the temperature guide pipe 3. A wave groove 503 is opened on the outside of the spiral pipe 502, and a temperature control component is set on the temperature guide pipe 3. The temperature control component pushes the wave groove 503 to rotate through the wave groove 503, thereby controlling the relative rotational deviation between the baffle 505 and the opening of the fixed plate 501.

[0026] Furthermore, the temperature control component includes a sleeve 6 fixedly fitted onto the temperature-conducting tube 3. The sleeve 6 is filled with gas. The sleeve 6 monitors the temperature of the liquid in the outlet of the temperature-conducting tube 3. The gas expands as the temperature rises and contracts as the temperature falls. An L-shaped tube 601 is fixed to one side of the sleeve 6. A sliding rod 602 is slidably inserted into the end of the L-shaped tube 601. When its temperature reaches a certain threshold, the expanding gas pushes the sliding rod 602 out along the L-shaped tube 601. A protruding rod is fixedly connected to one side of the sliding rod 602, and the end of the protruding rod is slidably inserted into the corrugated groove 503. The sliding rod 602 controls the protruding rod to slide along the corrugated groove 503 and pushes the rotating tube 502 to rotate.

[0027] Furthermore, the heat-conducting pipe 3 must always be filled with water. When the photovoltaic panel 1 is in the working state of converting light into electricity during the day, the liquid in the heat-conducting pipe 3 absorbs heat to cool the photovoltaic panel 1. When the photovoltaic panel 1 stops working at night, the heat-conducting pipe 3 insulates the photovoltaic panel 1 through the heat-conducting layer 2. Reducing the large temperature difference is beneficial to extending the service life of the photovoltaic panel 1.

[0028] Typically, most commercially available heat transfer devices are designed for constant high-temperature environments. They can stably and effectively transfer or manage heat sources with minimal temperature fluctuations. However, the situation is quite different when dealing with special applications such as photovoltaic panels. As solar energy capturers, the surface temperature of photovoltaic panels is not constant but fluctuates dynamically with changes in the duration and intensity of direct sunlight. This temperature non-constancy places more complex and precise control requirements on heat transfer devices. To address this, this device combines temperature control components and flow control components to monitor the temperature of the liquid inside the heat pipe in real time, accurately sense temperature changes, and intelligently adjust the flow rate of the liquid inside the heat pipe to ensure that the liquid temperature is always maintained within a safe high-temperature threshold range.

[0029] This dynamic adjustment mechanism not only avoids heat loss or safety hazards caused by excessively high liquid temperatures, but also significantly improves heat transfer efficiency, allowing the heat energy generated on the surface of the photovoltaic panel to be collected to the maximum extent and converted into usable energy. In addition, this intelligent and refined heat recovery strategy helps to extend the service life of the photovoltaic panel and improve its overall economic and environmental benefits.

[0030] The water tank 4 is equipped with an insulation layer, and the bottom of the sleeve 6 is equipped with a float 7. The float 7 is used to monitor the water level in the water tank 4. Two sets of telescopic rods 701 are fixedly connected between the sleeve 6 and the float 7. With the support of the telescopic rods 701, the float 7 can float up and down with the water level in the water tank 4. A control button 702 is fixedly installed at the bottom of the sleeve 6. When the water level in the water tank 4 reaches a certain height, it pushes the float 7 up to trigger the control button 702. The control button 702 controls the drain outlet of the water tank 4 to drain water.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
