Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic curtain walls, and specifically relates to a heat dissipation mechanism for a photovoltaic curtain wall. Background Art

[0002] A photovoltaic curtain wall, also known as an optoelectronic curtain wall, is a device fixed on glass that can convert light energy into electrical energy through batteries. Since a photovoltaic curtain wall can convert light energy and radiant energy into electrical energy and effectively utilize light energy and radiant energy, the common installation locations of current photovoltaic curtain walls are places with good lighting such as building exteriors.

[0003] During the use of a photovoltaic curtain wall, since it converts and uses light energy and radiant energy and is installed in a place with good lighting, the surface temperature of the photovoltaic curtain wall will be relatively high. Such a high temperature will cause the following problems to the operation of the photovoltaic curtain wall. First, it affects the power generation efficiency of the photovoltaic curtain wall. Generally, for every 1°C increase in the temperature of photovoltaic materials, the efficiency of photovoltaic materials will decrease by approximately 0.3% - 0.5%. Second, it reduces the service life of the photovoltaic curtain wall. High temperature will accelerate the aging process of photovoltaic materials and related components. Third, it affects the use safety of the photovoltaic curtain wall. When the temperature of the photovoltaic curtain wall is too high, it may cause electrical failures such as short circuits and leakage, posing certain safety hazards.

[0004] Therefore, in order to solve the above problems, a heat dissipation mechanism for a photovoltaic curtain wall is needed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a heat dissipation mechanism for a photovoltaic curtain wall, which solves the problem of affecting the power generation efficiency of the photovoltaic curtain wall when the overall temperature of the photovoltaic curtain wall is relatively high, extends the service life of the photovoltaic curtain wall, and avoids the problem that the photovoltaic curtain wall may cause electrical failures such as short circuits and leakage due to excessive temperature.

[0006] To achieve the above object, the present invention provides the following technical solution: A heat dissipation mechanism for a photovoltaic curtain wall includes a photovoltaic panel body and a photovoltaic junction box fixedly installed behind the photovoltaic panel body. A water supply mechanism and an air supply mechanism are installed above the photovoltaic junction box at the back of the photovoltaic panel body, and the water supply mechanism is directly above the air supply mechanism. A water spray pipe is fixedly installed on the upper side of the front of the photovoltaic panel body through a plurality of fixing blocks, and a plurality of atomizing nozzles are fixedly installed on the rear side of the water spray pipe;

[0007] On the opposite side of the top surface of the air supply mechanism, a pump air pipe and a water supply pipe are respectively fixedly installed, and the front ends of the pump air pipe and the water supply pipe both penetrate the surface of the photovoltaic panel body and are fixedly connected to the water spray pipe. On the top of the photovoltaic junction box, two sealing cylinders are fixedly installed through a heat conducting plate, and the surface of the sealing cylinder is fixedly installed with the water supply mechanism. A piston block is movably installed on the inner wall of each of the two sealing cylinders, and a push block is fixedly installed on the top surface of the piston block. The top surface of the heat conducting plate is fixedly connected to the bottom surface of the sealing cylinder. By using the seal of the piston block, a sealed space is formed between the sealing cylinder and the heat conducting plate, and a temperature-sensitive medium is filled in the sealed space.

[0008] Further, the water supply mechanism includes a water supply shell, a sealing baffle for sealing, a partition plate for separating fixedly installed on the top surface of the sealing baffle, and a gate plate vertically and perpendicularly movably installed on the partition plate.

[0009] Further, the air supply mechanism includes an L-shaped fixing block, and liquid chambers and air chambers are opened on the left and right sides inside the L-shaped fixing block. On the front side of the inner wall of the air chamber, an air delivery cylinder for extrusion and air delivery is fixedly installed through a plurality of connecting blocks.

The upper ends of the two side push rods are fixedly installed together with a pulling block for pulling, and a pull rod is fixedly installed on the surface of the pulling block. The side of the rod arm of the pull rod away from the sealing cylinder is movably erected inside the air chamber through a mounting block. Air vents are opened in the middle of the front and rear sides of the inner wall of the sealing cylinder, and check valves for check are fixedly installed on the inner walls of the two air vents. Pumping piston blocks for pushing air are fixedly installed on the opposite sides of the pull rod and the push rod. An air guide port for air intake is opened above the right side of the inner wall of the air chamber.

[0011] Further, the right end of the second rotating rod penetrates the inner wall of the liquid chamber and extends into the air chamber.

The end of the crankshaft rod away from the second rotating rod is rotatably connected to the inner wall of the air chamber. The front surface of the mounting block is fixedly connected to the front side of the inner wall of the air chamber.

[0012] Further, the upper end of the conveying vertical pipe penetrates the bottom surface of the L-shaped fixing block and extends into the liquid chamber. Each of the plurality of water-pushing blocks has an arc-shaped groove structure and is arranged in a circumferential and integral column on the rod arm of the first rotating rod.

[0013] Furthermore, several of the atomizing nozzles are equidistantly arranged on the pipe wall of the water spray pipe, and several atomizing nozzles are inclined, with the inclined direction being that the side closer to the photovoltaic panel body is higher than the other side.

[0018] Compared with the prior art, the present invention provides a heat dissipation mechanism for a photovoltaic curtain wall, having the following beneficial effects:

[0019] 1. The device adopts a structure that can automatically spray water and gas on the overall surface to cool down when the temperature is relatively high, avoiding the problem of the overall high temperature of the device, improving the power generation efficiency of the photovoltaic curtain wall, increasing the service life of the photovoltaic curtain wall, and avoiding potential electrical faults such as short circuits and electric leaks caused by excessive temperature of the photovoltaic curtain wall.

[0020] 2. The device utilizes different convex structures of the crankshaft rod to drive the pull rod box and the push rod to move relatively or in the opposite direction. In this way, through the relative or opposite movement of the pump air piston blocks connected to the pull rod and the push rod, suction and blowing operations can be performed through the vent, and air pumping operations can be carried out into the water spray pipe, enabling the liquid in the water spray pipe to contain gas, reducing the energy waste problem during the water spraying process of the water delivery pipe. Moreover, the atomizing nozzles adopted in this device have a greater atomizing water pressure and a larger water coverage area compared to ordinary nozzles, and can more effectively remove the heat from the surface of the photovoltaic panel, improving the heat dissipation effect.

[0021] 3. The device utilizes the arc-shaped groove structure of the shift block to ensure that the water flowing through the shift block will drive the shift block to rotate around the first rotating rod, and then the rotation of the first rotating rod drives the structure in the air cavity to perform the pumping operation, thereby avoiding the problem of requiring additional energy in the pumping process. The heat conducting plate and the aluminum alloy heat conducting strip on the heat conducting plate provided on the photovoltaic junction box can better ensure the self-starting cooling of the surface of the photovoltaic panel when the temperature is high.

[0022] 4. The device utilizes the position settings of the delivery riser and the water inlet pipe to ensure that after the gate door panel moves to a position that coincides with the inner wall of the partition plate, the water in the water inlet pipe can be delivered to the liquid cavity through the delivery riser, thereby driving the structure in the liquid cavity to operate and providing power for the pumping movement of the pumping mechanism.

[0023] 5. The device utilizes the opposite settings of two check valves to ensure the gas delivery operation of suction and pumping gas in the sealing cylinder, ensure the gas addition of the water delivery pipe, and utilizes the settings of fixed groove plates and connecting blocks to facilitate the connection effect of the overall device with other equipment, ensuring the basic fixed connection of the device.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 11 , a heat dissipation mechanism for a photovoltaic curtain wall in this embodiment includes a photovoltaic panel body 1 and a photovoltaic junction box 2 fixedly installed behind the photovoltaic panel body 1. A water delivery mechanism 3 and an air delivery mechanism 4 are installed above the photovoltaic junction box 2 at the back of the photovoltaic panel body 1, and the water delivery mechanism 3 is directly above the air delivery mechanism 4.

The temperature-sensitive medium in this device can be any one of ethanol, temperature-sensitive paraffin, and shape memory alloy. During the movement of the piston block 12, the operation of the water supply mechanism 3 can be ensured. When the water supply mechanism 3 operates, the water delivery force of the water flow can drive the structure in the air supply mechanism 4 to operate.

[0039] The water supply mechanism 3 includes a water supply shell 301, a sealing baffle 302 for sealing, and a partition plate 303 for partitioning fixedly installed on the top surface of the sealing baffle 302. A gate plate 304 is vertically and movably installed on the partition plate 303. On the surface of the water supply shell 301, a water inlet pipe 305 for water supply and a conveying vertical pipe 306 for water outlet are fixedly installed. The air supply mechanism 4 includes an L-shaped fixing block 401, a liquid cavity 402 and an air cavity 403 opened on the left and right sides inside the L-shaped fixing block 401. On the front side of the inner wall of the air cavity 403, an air delivery cylinder 406 for extrusion is fixedly installed through a plurality of connecting blocks 405. On the opposite sides of the inner wall of the liquid cavity 402, a plurality of water-pushing blocks 408 are fixedly installed through a first rotating rod 407. The right end of the first rotating rod 407 is rotatably installed with a crankshaft rod 410 for pushing through a second rotating rod 409, and the rod arm of the crankshaft rod 410 is erected inside the air cavity 403 through a plurality of vertical blocks 411.

[0040] Push rods 412 for pushing are rotatably installed at several protruding positions of the rod arm of the crankshaft rod 410. The upper ends of the two side push rods 412 are fixedly installed with a pulling block 413 for pulling, and a pull rod 414 is fixedly installed on the surface of the pulling block 413. The side of the rod arm of the pull rod 414 away from the sealing cylinder 11 is movably erected inside the air cavity 403 through a support block 415. Ventilation openings 416 are opened in the middle of the front and rear sides of the inner wall of the sealing cylinder 11, and check valves 417 for check are fixedly installed on the inner walls of the two ventilation openings 416. Pumping piston blocks 418 for pushing air are fixedly installed on the opposite sides of the pull rod 414 and the push rod 412. An air guiding port 419 for air intake is opened above the right side of the inner wall of the air cavity 403.

[0041] Among them, the right end of the second rotating rod 409 penetrates through the inner wall of the liquid chamber 402 and extends into the air chamber 403. The length of the middle push rod 412 is set to one-third of the length of the side push rod 412. One end of the crankshaft rod 410 away from the second rotating rod 409 is rotatably connected to the inner wall of the air chamber 403. The front surface of the mounting block 415 is fixedly connected to the front side of the inner wall of the air chamber 403. The upper end of the conveying vertical pipe 306 penetrates through the bottom surface of the L-shaped fixing block 401 and extends into the liquid chamber 402. A number of shifting blocks 408 are all arc-shaped groove structures and are arranged in a circumferential array on the rod arm of the first rotating rod 407.

[0042] Specifically, a number of atomizing nozzles 7 are equidistantly arranged on the pipe wall of the water spraying pipe 6, and a number of atomizing nozzles 7 are inclined, and the inclination direction is that the side close to the photovoltaic panel body 1 is higher than the other side. The heat conducting plate 10 is a rectangular plate made of aluminum alloy, and a number of aluminum alloy heat conducting strips 1001 are fixedly installed on the surface of the heat conducting plate 10. The width of the gate plate 304 is larger than the diameter of the partition plate 303 and is located inside the partition plate 303. The surface of the sealing baffle 302 is movably installed on the inner wall of the water delivery shell 301 and is located on the lower side of the inner wall of the water delivery shell 301. The water inlet pipe 305 penetrates through the surface of the water delivery shell 301 and is located inside the partition plate 303. The lower end of the water delivery pipe 9 penetrates through the surface of the L-shaped fixing block 401 and extends into the liquid chamber 402 and is located directly above the conveying vertical pipe 306. The conveying vertical pipe 306 penetrates through the surface of the water delivery shell 301 and is fixedly installed with the partition plate 303. The conveying vertical pipe 306 and the water inlet pipe 305 are arranged in front of and behind the gate plate 304.

[0043] It should be noted that the check directions of the two check valves 417 are set in opposite directions. The lower end of the pump air pipe 8 penetrates through the top surface of the L-shaped fixing block 401 and extends into the air chamber 403 and is fixedly installed with the inner wall of the front ventilation port 416. Both the upper and lower sides of the back surface of the photovoltaic panel body 1 are fitted with fixing groove plates 15 for fixing through a number of clamping blocks 14, and the vertical cross-sections of the fixing groove plates 15 and the clamping blocks 14 are both T-shaped. The structural settings of the fixing groove plates 15 and the clamping blocks 14 facilitate the better installation of the photovoltaic panel body 1 and enhance the convenient installation effect of the device.

[0044] The working principle of the above embodiment is as follows:

[0045] When the device is in use, the water in the building floor is fixed to the water inlet pipe 305, and ethanol liquid is previously filled on one side of the inner wall of the sealing cylinder 11 of the device close to the heat conducting plate 10. Through the sealing of the heat conducting plate 10, it is ensured that the ethanol liquid can push the structure on the piston block 12 to move after being heated and expanded;

[0046] When the photovoltaic panel body 1 is working, a large amount of heat will be generated on the surface of the photovoltaic panel body 1, and the heat will be gathered around the photovoltaic panel body 1. Since there is a lot of heat around the photovoltaic panel body 1, the piston block 12 can drive the push block 13 to push the sealing baffle 302 to move upward through the conduction of the heat conducting plate 10. The process of the sealing baffle 302 moving upward will cause the gate door panel 304 and the inner wall of the partition plate 303 to overlap, so that the water in the water inlet pipe 305 will pass through the gate door panel 304 and the inner wall of the partition plate 303. The water in the delivery vertical pipe 306 enters the liquid cavity 402. The water entering the liquid cavity 402 will first move the dial block 408 to drive the first rotating rod 407 to rotate. The water flowing into the liquid cavity 402 will enter the water spray pipe 6 through the water delivery pipe 9, and then be sprayed out through the atomizing nozzle 7 on the water spray pipe 6. The surface of the photovoltaic panel body 1 is cooled by the evaporation heat absorption effect of the atomized water.

[0047] During the liquid delivery process, the first rotating rod 407 drives the crankshaft rod 410 to rotate through the second rotating rod 409. The arm of the crankshaft rod 410 is bent and has a plurality of protrusions. The crankshaft rod 410 drives the push rod 412 to move up and down. Because the bending of the crankshaft rod 410 arm is S-shaped, the two adjacent protrusions of the crankshaft rod 410 arm are in opposite directions. In this way, the protrusion in the middle points upward, and the protrusion on the peripheral side points downward. In this way, when the crankshaft rod 410 rotates, the middle part The push rod 412 and the push rod 412 on the side are in opposite movement state, which causes the movement direction of the middle push rod 412 and the pull rod 414 to be relatively opposite, thereby ensuring that the pump piston block 418 moves relative or oppositely. Because the pump piston block 418 is arranged in the air delivery cylinder 406, in the relative or opposite movement process, it can be ensured that the air delivery cylinder 406 generates an air pressure difference, and the arrangement of the two air vents 416 and the internal check valve 417 can ensure that when the two pump piston blocks 418 are far away from each other, The gas in the gas cylinder 406 will be sucked into the gas cylinder 406 through the front air vent 416. When the two gas pump piston blocks 418 move relative to each other, the gas will be discharged through the rear air vent 416 and enter the pump air pipe 8. In this way, the gas enters the water spray pipe 6 through the pump air pipe 8. In this way, the water spray pipe 6 will contain gas. When gas is added to the water spray pipe 6, a gas-water mixed flow will be formed. The addition of gas can occupy a certain space, causing water to flow in the water spray pipe 6 in a discontinuous state, forming a similar "plunger flow". Or "bubble flow" and other flow types, so that during the flow process, the water does not completely fill the entire cross-section of the pipe, so that under the same flow demand, the actual amount of water can be reduced, thereby ensuring that the overall device reduces the use of water resources while cooling the photovoltaic panel body 1. A check valve 417 is set in the gas cylinder 406. The front check valve 417 can ensure that the gas cylinder 406 has an effect of inhaling but not exhaling, and the rear check valve 417 can ensure that the gas cylinder 406 has an effect of exhaling but not inhaling, thereby ensuring the basic use function of the device;

[0048] When the temperature on the peripheral side of the photovoltaic panel body 1 decreases, the ethanol liquid will contract, and then the piston block 12 in the sealing cylinder 11 will drive the push block 13 to move the sealing baffle 302 downward. This will drive the gate plate 304 on the sealing baffle 302 to move away from the partition plate 303. In this way, the inner walls of the partition plate 303 and the gate plate 304 are staggered, and the water in the water inlet pipe 305 can be prevented from entering the water spray pipe 6. Furthermore, the water spray cooling effect of the water spray pipe 6 is explained, ensuring the function that the device automatically cools down when the temperature of the photovoltaic panel body 1 is high. The water spray pipe 6 of the device is arranged on one side of the top of the photovoltaic panel body 1 and will not affect the normal light absorption and power generation function of the photovoltaic panel body 1. The innovative structure of the device will not be elaborated too much on the prior art.

[0049] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technology also belongs to the common knowledge in this field. Therefore, the specific structural composition and working principle will not be elaborated too much in this embodiment.
