Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, and in particular to a heat dissipation structure of a photovoltaic component. Background Art

[0002] Photovoltaic panels, also known as solar panels, are devices that convert solar radiation into electrical energy using the photoelectric effect when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon);

[0003] Photovoltaic panels generate heat when converting solar energy into electrical energy. At the same time, since they are installed on the roof, the ventilation conditions at the back plate are poor, so the back plate temperature of the component will be higher than the surface temperature of the component. As the temperature rises, the photoelectric conversion rate of the photovoltaic panel will decrease, affecting the conversion efficiency, so it is necessary to dissipate heat for it.

[0004] Traditional photovoltaic panels have two methods of heat dissipation: fan cooling and spray cooling. Fan cooling mainly uses fans to accelerate air circulation to achieve heat dissipation effects. Spray cooling mainly sprays water on photovoltaic panels and uses water to absorb heat and evaporate to cool them down. However, both methods have disadvantages. First, since photovoltaic panels are installed outdoors, the air driven by fans is hot air, which has little cooling effect. Spray cooling targets the surface of photovoltaic panels and cannot effectively cool down the heat inside the photovoltaic panels. It also increases water resource costs. Summary of the invention

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention.

[0038] Example 1

[0039] Reference Figure 1 , provides a schematic diagram of the overall structure of the heat dissipation structure of a photovoltaic module, such as Figure 1-3 , a photovoltaic module heat dissipation structure, comprising:

[0040] The water-cooled heat dissipation part 100 includes a heat exchange plate 101 and a heat exchange coil 102 disposed on one side of the heat exchange plate 101. A pipe assembly 103 is installed on the heat exchange coil 102, which uses water flowing through the heat exchange coil 102 to exchange heat on the surface of the heat exchange plate 101;

[0041] Specifically, the heat exchange plate 101 is made of copper-plated aluminum and has a high heat exchange performance. The surface of the heat exchange plate 101 is provided with an embedding groove corresponding to the position of the heat exchange coil 102. The heat exchange coil 102 is embedded in the embedding groove of the heat exchange plate 101 and fixed on the surface by soldering. The embedded installation allows the heat exchange coil 102 to have more contact with the heat exchange plate 101, thereby maximizing the heat exchange performance.

[0042] Specifically, there are no less than five heat exchange coils 102, which are respectively arranged in five areas, and the five heat exchange coils 102 are relatively independent, so the effect of independent cooling of multiple areas is achieved.

[0043] Furthermore, the heat exchange coil 102 includes a coil 102a, the two ends of the coil 102a are respectively a water inlet 102b and a water outlet 102c, and a sleeve 102d is equidistantly connected to the coil 102a, and a heat shrinkable and cold expansion member 102e is embedded and installed inside the sleeve 102d.

[0044] Specifically, the heat shrinkable and cold expansion component 102e is annular in structure and is made of vulcanized rubber. Vulcanized rubber has the function of heat shrinkage and cold expansion. It is embedded and installed on the inner side of the sleeve 102d. When the water source flows through it and the heat exchange reaches about 50 degrees, the heat shrinkable and cold expansion component 102e shrinks, thereby making the inner space of the heat shrinkable and cold expansion component 102e larger, and then the water flow rate increases, thereby improving the heat exchange effect of the area. When the temperature of the water flowing through the heat shrinkable and cold expansion component 102e is lower than 50 degrees, the heat shrinkable and cold expansion component 102e gradually recovers to expand outward. After the outward expansion, its internal flow space becomes smaller and the flow rate becomes lower. Therefore, the extra water source can be supplied to the area with higher temperature, thereby realizing the role of self-regulation of the partition, and automatically adjusting the size of the water flow according to the temperature of each zone to ensure that the temperature of each zone can be effectively reduced.

[0045] Furthermore, the pipeline assembly 103 includes a water collecting box 103a and a water collecting box 103b, which are respectively fixed on both sides of the heat exchange plate 101, the water outlet end of the water collecting box 103a is connected to the water inlet 102b, and the water inlet of the water collecting box 103a is connected to a water pipe 103c, and a water pump 103d is installed on the water pipe 103c, the water inlet end of the water collecting box 103b is connected to the water outlet 102c, and the water outlet end of the water collecting box 103b is connected to the return pipe 103e.

[0046] Specifically, the water inlet end of the water pipe 103c is connected to the water outlet end of the cooling tower, which is used to extract the cooled water in the cooling tower. The extracted water enters the water collecting box 103a and then enters the five heat exchange coils 102 respectively. The heat exchange coils 102 absorb the heat of the heat exchange plate 101 for heat exchange, so that the temperature of the heat exchange plate 101 is reduced.

[0047] Operation process: When cooling, the heat exchange plate 101 is installed on the back side of the photovoltaic panel to absorb the heat generated by the photoelectric conversion inside the photovoltaic panel. The water inlet end of the water pipe 103c is connected to the water outlet end of the cooling tower to extract the water source after cooling in the cooling tower. The extracted water source enters the water collecting box 103a and then enters the heat exchange coil 102. The heat exchange coil 102 absorbs the heat of the heat exchange plate 101 for heat exchange, so that the temperature of the heat exchange plate 101 is reduced, thereby reducing the temperature inside the photovoltaic panel.

[0048] There are five heat exchange coils 102, and they are independently divided into zones. Each of the five coils 102a is provided with a heat shrinkable and cold expansion member 102e. The heat shrinkable and cold expansion member 102e is in an annular structure and is made of vulcanized rubber. The vulcanized rubber has the function of heat shrinkage and cold expansion. The heat shrinkable and cold expansion member 102e is embedded and installed on the inner side of the sleeve 102d. When the water source flows through the heat exchange to about 50 degrees, the heat shrinkable and cold expansion member 102e shrinks, thereby making the inner space of the heat shrinkable and cold expansion member 102e larger, thereby increasing the water flow rate, thereby improving the heat exchange effect of the area. When the temperature of the water flowing through the heat shrinkable and cold expansion member 102e is lower than 50 degrees, the heat shrinkable and cold expansion member 102e gradually recovers to expand outward. After the expansion, the internal flow space becomes smaller and the flow rate becomes lower. Therefore, the extra water source can be supplied to the area with higher temperature, thereby realizing the role of self-regulation of the zone, and automatically adjusting the size of the water flow according to the temperature of each zone to ensure that the temperature of each zone can be effectively reduced.

[0049] Example 2

[0050] Reference Figure 4-8 This embodiment is different from the first embodiment in that: this embodiment is a photovoltaic module heat dissipation structure, and further includes:

[0051] The plate heat dissipation part 200 includes a heat dissipation main pipe 201 opened inside the heat exchange plate 101 and a heat dissipation groove 202 penetrating the surface of the heat exchange plate 101. The heat dissipation main pipe 201 and the heat dissipation groove 202 are connected through a capillary pipe 203, and a breathing airflow generating mechanism 204 is provided at one end of the heat dissipation main pipe 201;

[0052] The breathing airflow generating mechanism 204 includes a return water kinetic energy recovery component 204a and a pull-pull ventilation component 204b installed on one side of the heat exchange plate 101 and corresponding to one end of the heat dissipation main pipeline 201. The pull-pull ventilation component 204b is connected to the heat dissipation main pipeline 201, and the return water kinetic energy recovery component 204a is used to drive the pull-pull ventilation component 204b to perform piston movement.

[0053] Furthermore, the return water kinetic energy recovery component 204a includes a column box 204a-1, in which a rotating shaft 204a-2 is rotatably connected, and a water wheel 204a-3 is fixed to the outer sleeve of the rotating shaft 204a-2. The water wheel 204a-3 is driven to rotate by the return water of the return water pipe 103e.

[0054] Specifically, a return water inlet 204a-4 and a drain hole 204a-5 are provided on the outside of the column box 204a-1. The return water inlet 204a-4 is connected to the water outlet end of the return water pipe 103e, and the drain hole 204a-5 is connected to the water inlet end of the cooling tower through a pipeline. The return water enters the column box 204a-1 through the return water inlet 204a-4, impacts the water wheel 204a-3 to make it rotate, and the water flow impacting the water wheel 204a-3 is then transported to the cooling tower through the drain hole 204a-5 and the pipeline for cooling.

[0055] Specifically, the blades on the outside of the water wheel 204a-3 are divided into six long blades and twelve short blades. There are two short blades distributed between every two adjacent long blades, and the ends of the long blades are in contact with the inner wall of the column box 204a-1. An independent water cavity is formed between every two adjacent long blades and the column box 204a-1. The distinction of multiple water cavities makes the amount of water in the column box 204a-1 small, which can avoid the problem of limited power of the water wheel 204a-3 in the entire water cavity (the more water sources, the more water will offset part of the incoming impact).

[0056] Furthermore, the pull-and-pull ventilation component 204b includes a connecting seat 204b-1, which is installed on one side of the heat exchange plate 101 and corresponds to the end position of the heat dissipation main pipe 201, and a piston cylinder 204b-2 is provided on one side of the connecting seat 204b-1, and the interior of the piston cylinder 204b-2 is movably connected to a piston 204b-3, one end of the piston 204b-3 is rotatably connected to a driving rod 204b-4, and the other end of the driving rod 204b-4 is rotatably connected to a driving disk 204b-5.

[0057] Specifically, an air cavity is provided in the connection seat, and the air cavity is connected to the piston cylinder 204b-2 and one end of the heat dissipation main pipeline 201;

[0058] Specifically, the driving rod 204b-4 is rotatably connected to the edge of the driving disk 204b-5 to form an eccentric structure, and the axis of the driving disk 204b-5 is fixed to the rotating shaft 204a-2, and the water flow is used to drive the water wheel 204a-3 to rotate, thereby realizing the rotation of the driving disk 204b-5. After the driving disk 204b-5 rotates, it drives the driving rod 204b-4 to rotate eccentrically. At the same time, the other end of the driving rod 204b-4 is connected to the piston 204b-3 and is constrained by the piston cylinder 204b-2. Therefore, it can only force the piston 204b-3 to do piston motion in the piston cylinder 204b-2. During the movement, push and pull airflows are generated. During the push, the airflow enters the heat dissipation main duct 201 through the wind cavity. Part of the airflow entering the heat dissipation main duct 201 is discharged from the other end, and the other part is discharged from the heat dissipation groove 202 through the capillary duct 203. During the pull back, the external airflow is introduced and discharged from the heat dissipation barrel groove 202 again. The push and pull form breathing, which quickly leads the heat inside the heat exchange plate 101, effectively improving the heat exchange capacity of the heat exchange plate 101. The power of the plate heat dissipation part 200 comes from the water flow potential energy of the water-cooled heat dissipation part 100, without additional energy consumption, with the advantages of low cost and good heat dissipation effect.

[0059] Furthermore, the breathing airflow generating mechanism 204 also includes a one-way constraint component 204c, which is installed on the rotating shaft 204a-2 to limit its rotation direction.

[0060] Furthermore, the one-way constraint assembly 204c includes a ratchet 204c-1 which is sleeved and fixed on the rotating shaft 204a-2, and a claw 204c-2 is provided on one side of the ratchet 204c-1. One end of the claw 204c-2 is rotatably connected to the upper surface of the column box 204a-1 through a turn pin 204c-3, and the other end of the claw 204c-2 is against the teeth on one side of the ratchet 204c-1, and an elastic member 204c-4 is provided on the outer side of the claw 204c-2.

[0061] Specifically, the elastic member 204c-4 adopts a fixed column and a spring. The fixed column is fixed above the column box 204a-1 and located on one side of the claw 204c-2. The two ends of the spring are respectively fixedly connected to the fixed column and the outer side of the claw 204c-2.

[0062] The rest of the structure is the same as that of Example 1.

[0063] Operation process: The water wheel 204a-3 drives the rotating shaft 204a-2 to rotate while rotating, and the rotating shaft 204a-2 drives the ratchet 204c-1 to rotate. After the ratchet 204c-1 rotates, it will move the claw 204c-2 when rotating clockwise, causing the claw 204c-2 to rotate and compress the spring. At the same time, the reaction force of the spring will cause the claw 204c-2 to reset and get stuck between the teeth, so it will make a "click...click...click..." sound after rotation. If it rotates counterclockwise, the force direction will resist the claw 204c-2 and it will not be able to rotate, so it cannot be reversed, thereby ensuring that the rotation direction of the water wheel 204a-3 is consistent, avoiding steering confusion that affects the piston movement of the pull-pull ventilation component 204b.

[0067] Specifically, the detachable hanging assembly 301 includes an L-shaped block 301a, a clamping block 301b is arranged on the inner side of the L-shaped block 301a, and a threaded driving member 301c is arranged on the inner side of the L-shaped block 301a for driving the clamping block 301b to slide up and down along the inner wall of the L-shaped block 301a, a locking cavity 301d is arranged at the bottom of the L-shaped block 301a, and a resisting member 301e is arranged inside the locking cavity 301d, and a slideway is arranged on the inner side of the L-shaped block 301a, and a limiting slider is fixed on one side of the clamping block 301b, and the limiting slider slides in the slideway, and a threaded hole is arranged on the limiting slider, and a threaded rod extending into the slideway is rotatably connected to the upper side of the L-shaped block 301a, and the threaded rod is threadedly connected to the threaded hole, so rotating the threaded rod will cause the limiting slider to drive the clamping block 301b to move back and forth along the rotation direction of the thread of the threaded rod, so it can be clamped on the outer side of the photovoltaic panel;

[0068] Specifically, the fastening assembly 302 includes a fixing block 302a fixed to the outer side of the heat exchange plate 101, and the inner side of the fixing block 302a is rotatably connected to a rotating rod 302b, one end of the rotating rod 302b is symmetrically fixed with a locking block 302c, and the other end of the rotating rod 302b passes through the fixing block 302a and is fixed with a fastening button 302d, the opening of the locking cavity 301d is consistent with the through groove of the locking block 302c, and the interior of the locking cavity 301d is provided with a plurality of annular grooves, when fastening, the locking block 302c is inserted into the locking cavity 301d and then the fastening button 302d is rotated, and then the locking block 302c is driven by the rotating rod 302b to be screwed into the annular groove to complete the fixation, the abutment 301e adopts a tension spring, and the tension spring abuts against the bottom of the locking block 302c to have a relaxing effect, and the structure can be quickly and non-destructively installed on the back side of the photovoltaic panel, has the function of convenient disassembly and assembly, and is highly practical.
