Description

Technical Field

[0001] This utility model relates to the field of solar panel cooling technology, and in particular to a solar panel cooling device with a bent tube core. Background Technology

[0002] Solar power generators produce electricity by directly exposing solar panels to sunlight, which then charges batteries. This electricity can power products such as DC energy-saving lamps, radios, televisions, DVDs, and satellite TV receivers. However, solar photovoltaic panels generate heat during power generation. If heat dissipation is insufficient, the surface temperature of the photovoltaic panels can become excessively high, negatively impacting the system's conversion efficiency. For every 1°C increase in temperature, the output power of a solar photovoltaic panel decreases by 0.4%. Furthermore, exceeding the temperature limit accelerates the aging rate of silicon solar cells. Therefore, research on the cooling of photovoltaic panels is of great significance.

[0003] Existing solar panel cooling devices cool the solar panels by laying straight water pipes on the back of the solar panels and connecting them to tap water pipes. The flow of tap water through these pipes allows heat exchange between the solar panels and the water, thus cooling the panels. However, to achieve effective cooling, a continuous supply of tap water must be introduced into the spiral pipes, placing a significant burden on water resources and increasing storage costs. Furthermore, the lack of proper water reuse leads to water waste. Additionally, the short heat exchange path of the straight pipes limits the heat exchange area and time, resulting in low heat dissipation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a solar panel cooling device with a curved core to address the aforementioned problems. This device circulates and cools the solar panel, ensuring heat dissipation efficiency while reducing the amount of coolant used, lowering operating costs, saving resources, and reducing resource waste. Furthermore, the curved core is in close contact with the solar panel surface, significantly increasing the heat conduction area and accelerating the transfer of heat from the solar panel surface to the coolant, thereby improving the overall heat dissipation efficiency.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0008] The heat exchange assembly is connected to the second liquid collection pipe;

[0011] Preferably, the heat exchange core includes a plurality of heat exchange tubes, which are spaced apart, and fins are fixedly arranged between two adjacent heat exchange tubes. One end of each heat exchange tube is connected to the left water chamber, and the other end is connected to the right water chamber.

[0012] Preferably, the bent tube core includes multiple heat dissipation bends, which are spaced apart. The outer surface of each heat dissipation bend is in close contact with the solar panel. One end of each heat dissipation bend is connected to the first liquid collection pipe through a first interface, and the other end is connected to the second liquid collection pipe through a second interface.

[0013] Preferably, the contact surface of the heat dissipation bend that contacts the solar panel is planar.

[0014] Preferably, the heat dissipation bend includes a first U-shaped pipe segment and a second U-shaped pipe segment.

The second flat tube segment is inclined, and the end of the second flat tube segment away from the second circular tube segment is connected to the heat dissipation bend.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] This invention uses a liquid storage pump assembly to export cooling liquid, which is then introduced into a bent tube core through a first liquid collection pipe. The bent tube core cools the solar panel. The high-temperature cooling liquid is then sent to a heat exchange assembly through a second liquid collection pipe, where it is cooled down before being returned to the liquid storage pump assembly. This achieves cyclic cooling of the solar panel, reducing the amount of cooling liquid used while ensuring heat dissipation efficiency, lowering operating costs, saving resources, and reducing waste.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0025] Please see Figures 1 to 3 This utility model provides a solar panel cooling device with a bent tube core, the technical solution of which is as follows:

[0026] A solar panel 9 cooling device with a bent tube core 6 includes a liquid storage pumping assembly, a heat exchange assembly 5, a first liquid collecting pipe 3, a second liquid collecting pipe 10, and the bent tube core 6. The liquid storage pumping assembly includes a liquid storage tank 1 and a water pump. The upper end of the liquid storage tank 1 has an outlet 2, which is connected to the first liquid collecting pipe 3 via a pipe. The lower end of the liquid storage tank 1 has an inlet 4, which is connected to the heat exchange assembly 5 via a pipe. The water pump is fixedly installed inside the liquid storage tank 1 and is connected to the outlet 2.

[0027] The heat exchange assembly 5 includes a left water chamber 51, a right water chamber 52, a heat exchange core 53, and a cooling fan 54. The heat exchange core 53 includes multiple heat exchange tubes, which are spaced apart between the left and right water chambers 51 and 52. Fins are fixedly installed between adjacent heat exchange tubes. One end of each heat exchange tube is connected to the left water chamber 51, and the other end is connected to the right water chamber 52. The left water chamber 51 is connected to the inlet 4 of the liquid storage tank 1 via a pipe. The right water chamber 52 is connected to the second liquid collection pipe 10 via a pipe. The cooling fan 54 is fixedly installed in front of the heat exchange core 53 and directly opposite it. The right water chamber 52 receives the high-temperature cooling liquid after heat exchange from the second liquid collector 10. As the high-temperature cooling liquid flows through the heat exchange tubes, it undergoes heat exchange with the fins, transferring heat to the fins. The fins then exchange heat with the air, dissipating the heat into the air. The cooling fan 54 then blows air onto the fins to remove the hot air, effectively cooling the high-temperature cooling liquid. The cooled liquid reaches the left water chamber 51, is discharged from the left water chamber 51, and enters the liquid storage tank 1 through the inlet 4. The water pump in the liquid storage tank 1 then extracts the cooling liquid, discharges it through the outlet 2 to the first liquid collector 3, and then exchanges heat with the solar panel 9 through the bent tube core 6, thus achieving cyclic cooling of the solar panel 9. The cooling fan 54 works in conjunction with the finned heat exchange tubes, forcing air to flow through the fin gaps, significantly improving the heat dissipation efficiency of the heat exchange core 53. The fins further expand the heat dissipation surface area, reducing reliance on fan power and lowering system energy consumption.

[0028] The bent tube core 6 includes multiple heat dissipation bends arranged at intervals. The outer surface of the heat dissipation bends is in close contact with the back of the solar panel 9. Each heat dissipation bend includes a first U-shaped section 61 and a second U-shaped section 62. One end of the first U-shaped section 61 is connected to the first liquid collection pipe 3 via a first interface 7, and the other end is connected to the second U-shaped section 62. The end of the second U-shaped section 62 furthest from the first U-shaped section 61 is connected to the second liquid collection pipe 10 via a second interface 8. The orientation of the first U-shaped section 61 is opposite to that of the second U-shaped section 62. Cooling liquid exiting from the first liquid collection pipe 3 flows back into the heat dissipation bends via the first interface 7, and then exits into the second liquid collection pipe 10 via the second interface 8. The first interface 7 and the second interface 8 act as a buffer for the cooling liquid flow, effectively mitigating the adverse effects of excessive or prolonged water flow on the connection between the heat dissipation bend and the first or second liquid collector 3. Simultaneously, they ensure uniform heat dissipation, effectively preventing localized overheating of the solar panel 9 and thus extending its service life. The heat dissipation bend, composed of the first U-shaped pipe section 61 and the second U-shaped pipe section 62, increases the path the cooling liquid travels, increasing the heat exchange time and area, thereby improving heat dissipation efficiency.

[0029] Furthermore, to address the issue of the small contact area between the pipe and the solar panel 9, in this embodiment, the contact surface between the heat dissipation bend and the solar panel 9 is planar. Since the solar panel 9 is a flat plate, making the contact surface planar increases the contact area between the heat dissipation bend and the solar panel 9, thereby improving heat exchange efficiency.

[0030] Furthermore, to improve the contact between the heat dissipation bend and the solar panel 9 and solve the problem of complex installation, in this embodiment, the first interface 7 includes a first circular pipe segment 71 and a first flat pipe segment 72. One end of the first circular pipe segment 71 is connected to the first liquid collecting pipe 3, and the other end is connected to the first flat pipe segment 72. The first flat pipe segment 72 is inclined towards the solar panel 9. The end of the first flat pipe segment 72 away from the first circular pipe segment 71 is connected to the first U-shaped pipe segment 61. The second interface 8 includes a second circular pipe segment 81 and a second flat pipe segment 82. One end of the second circular pipe segment 81 is connected to the second liquid collecting pipe 10, and the other end is connected to the second flat pipe segment 82. The second flat pipe segment 82 is inclined towards the solar panel 9. The end of the second flat pipe segment 82 away from the second circular pipe segment 81 is connected to the second U-shaped pipe segment 62. By tilting the first flat tube segment 72 and the second flat tube segment 82, the heat dissipation bend can be installed above the plane defined by the first liquid collecting pipe 3 and the second liquid collecting pipe 10. This allows the heat dissipation bend to more easily contact the back of the solar panel 9 during installation, improving installation efficiency and the contact degree between the heat dissipation bend and the solar panel 9. The angles formed by the first flat tube segment 72 and the second flat tube segment 82 with the solar panel 9 are 15-45°. By setting a certain angle, the effective heat exchange length of the heat dissipation bend is guaranteed while ensuring convenient installation and heat exchange efficiency. At the same time, it reduces space occupation and facilitates installation with solar panels 9 of different specifications. The connection between the first round tube segment 71 and the second round tube segment 81 and the liquid collecting pipe is facilitated by the round tube, which is more conducive to welding and processing of the liquid collecting pipe, reducing manufacturing difficulty.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
