Description

Technical Field

[0001] This application relates to the field of photovoltaic energy storage equipment technology, and in particular to a wind deflector and photovoltaic equipment. Background Technology

[0002] Currently, photovoltaic equipment such as inverters typically includes a chassis, functional components, cooling fans, and an air guide shroud. The functional components and cooling fans are located on the outside of the chassis, and the air guide shroud covers them. The air guide shroud has multiple ventilation holes, forming a heat dissipation channel. The cooling fans promote gas exchange between the inside and outside of the air guide shroud through the heat dissipation channel, achieving a heat dissipation effect. To improve heat dissipation efficiency, the heat dissipation channel often has a large number of ventilation holes at the air inlet and outlet. However, dust and debris may enter the air duct through the ventilation holes and accumulate, thus affecting the machine's heat dissipation performance. Therefore, regular dust removal of the inside of the air guide shroud is necessary.

[0003] In related technologies, dust removal is typically achieved through the reverse blowing of a cooling fan. Before the equipment starts, the cooling fan reverses direction for a period of time to blow dust and debris from inside the air guide shroud out through the ventilation holes. However, due to the dense arrangement of functional components inside the air guide shroud, most of the dust and debris still adheres to these components, thus the dust removal effect needs improvement. Utility Model Content

[0004] Therefore, this application provides an air guide cover and a photovoltaic device, which have the technical effect of facilitating dust removal.

[0005] The first aspect of this application provides a wind deflector for use in photovoltaic equipment. The photovoltaic equipment includes a chassis, functional devices, and heat dissipation components. The wind deflector includes: a first cover for mounting on the chassis and having a first ventilation hole; a second cover for mounting on the chassis and having a second ventilation hole; a receiving space is formed between the second cover and the chassis for accommodating the functional devices and heat dissipation components; wherein the upper end of the second cover has a mounting port communicating with the receiving space; the first cover is detachably connected to the upper end of the second cover and covers the mounting port.

[0006] In some embodiments, the first ventilation hole is formed on the periphery of the first cover.

[0007] In some embodiments, the upper end of the first cover protrudes upward relative to the upper end of the chassis.

[0008] In some embodiments, the second ventilation hole is formed on the bottom surface of the second cover.

[0009] In some embodiments, the relative distribution direction of the first ventilation hole and the second ventilation hole is parallel to the airflow direction of the heat dissipation component.

[0010] In some embodiments, the first cover and the second cover are inserted and fitted together in the vertical direction. Guide blocks are respectively provided on both sides of the first cover. The two guide blocks are respectively positioned with the second cover in the first direction. There is an angle between the first direction and the vertical direction.

[0011] In some embodiments, the guide block is provided with a mounting hole for a fastener to pass through, and the guide block is fixed to the second cover by the fastener.

[0012] In some embodiments, a positioning plug is provided at the lower end of the first cover; the positioning plug is inserted into the mounting port and abuts against the inner side of the mounting port along the second direction, and the second direction has an angle with the first direction.

[0013] In some embodiments, the second cover is provided with a guide flange, which is inserted into the first cover in the vertical direction. The guide flange has a positioning port for the positioning block to be inserted, and the positioning block is limited to the positioning port in the first direction.

[0014] The second aspect of this application provides a photovoltaic device, including a chassis, a heat dissipation component, functional devices, and a wind deflector as provided in the first aspect, wherein the heat dissipation component and the functional devices are disposed on the outside of the chassis; the wind deflector is connected to the chassis and covers the heat dissipation component and the functional devices.

[0015] With the air guide cover and photovoltaic equipment provided in this application, when dust removal is required inside the air guide cover, the first cover can be detached from the top of the second cover, exposing the accommodating space. Users can then access the accommodating space through the installation port using tools such as a blower to clean accumulated dust and debris from the heat dissipation components and functional devices. After dust removal, the first cover can be reattached to the second cover. This separate design of the first and second covers allows users to open the first cover directly to clean the interior of the accommodating space, facilitating dust removal and improving dust removal efficiency and heat dissipation performance. Furthermore, users only need to disassemble the first cover for dust removal; they do not need to disassemble the heat dissipation components or the entire air guide cover. This significantly simplifies maintenance operations, saves manpower, and reduces machine failures caused by human error, while still meeting the machine's heat dissipation and dust removal functions.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0030] In the description of the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being better or more advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. The directional descriptions of the embodiments of this application are based on the directions illustrated in the appended specification, and are intended to provide a clearer description of the solution, not to limit the specific direction of the product in use.

[0031] In related technologies, considering the heat dissipation rate, the heat dissipation duct of the air guide shroud often has a large number of ventilation holes at the air inlet and outlet. However, this design also causes dust and debris to enter the air guide shroud through the ventilation holes and accumulate continuously, thus affecting the heat dissipation performance of the machine. Therefore, it is necessary to regularly clean the inside of the air guide shroud.

[0032] In related technologies, dust removal is typically achieved through the reverse blowing of a cooling fan. Before the equipment starts, the cooling fan reverses direction for a period of time, blowing dust and debris from inside the air guide shroud out through the ventilation holes. However, the internal structure of the air guide shroud is complex, with densely packed functional components. Most of the dust blown out by the fan in reverse direction adheres to these components, resulting in poor dust removal. Further dust removal inside the air guide shroud requires disassembling the entire shroud, which is cumbersome and may cause machine malfunction.

[0033] This application provides an air guide cover and a photovoltaic device, which have the characteristics of better dust removal effect and better heat dissipation performance.

[0034] Figure 1 This is a structural schematic diagram of the photovoltaic equipment provided in this application. Figure 2 The schematic diagram of the chassis, heat dissipation components and functional devices provided in this application.

[0035] like Figure 1 and Figure 2 As shown, this application embodiment first provides an air guide shroud 100, which is used in conjunction with the heat dissipation assembly 300. The air guide shroud 100 is used to cover the heat dissipation assembly 300, and has multiple ventilation holes. The air guide shroud 100 protects the heat dissipation assembly 300 and also serves to ventilate and guide airflow.

[0036] The air guide shroud 100 can be applied to a photovoltaic device 1000. In the example of this application, the photovoltaic device 1000 can be an inverter, and the photovoltaic device 1000 includes a chassis 200, a heat dissipation assembly 300, functional devices 400, and an air guide shroud 100, wherein the heat dissipation assembly 300 and the functional devices 400 are disposed on the outside of the chassis 200. The air guide shroud 100 is connected to the chassis 200 and covers the heat dissipation assembly 300 and the functional devices 400. Exemplarily, the chassis 200 has a front and a back, and the heat dissipation assembly 300 and the functional devices 400 are both disposed on the back of the chassis 200. The heat dissipation assembly 300 can be a combination of a cooling fan 301 and a mounting bracket 302. The functional devices 400 can be a finned heat sink 401, an inductor 402, a heat exchanger 403, etc.

[0037] Figure 3 A structural schematic diagram of the first cover provided in this application from a first-view perspective. Figure 4A structural schematic diagram of the first cover provided in this application from a second perspective. Figure 5 A schematic diagram of the structure of the second cover provided in this application.

[0038] Please refer to the following: Figures 3 to 5 In this embodiment, the air guide shroud 100 includes a first shroud 10 and a second shroud 20. The first shroud 10 has a first ventilation hole 11 and is disposed in the chassis 200. The second shroud 20 has a second ventilation hole 21 and is disposed in the chassis 200. A heat dissipation air duct is formed between the first ventilation hole 11 and the second ventilation hole 21. An accommodating space 22 is formed between the second shroud 20 and the chassis 200. The accommodating space 22 is used to accommodate the functional device 400 and the heat dissipation assembly 300. The upper end of the second shroud 20 has a mounting port 221 communicating with the accommodating space 22. The first shroud 10 is detachably connected to the upper end of the second shroud 20 and covers the mounting port 221.

[0039] When the equipment is working normally, the first cover 10 covers the mounting port 221 to cooperate with the second cover 20 to protect the heat dissipation component 300 and the functional device 400. At the same time, the heat dissipation component 300 can dissipate heat through the heat dissipation air duct formed between the first ventilation hole 11 and the second ventilation hole 21.

[0040] Figure 6 This is a schematic diagram showing the state where the first cover is separated from the upper end of the second cover, as provided in this application.

[0041] Please refer to the following: Figure 6 When it is necessary to remove dust from the inside of the air guide cover 100, the first cover 10 can be removed from the top of the second cover 20 so that the accommodating space 22 is exposed in the second cover 20. The user can enter the accommodating space 22 through the installation port 221 with tools such as a hot air gun to clean the dust and debris accumulated in the heat dissipation component 300 and the functional device 400. After the dust removal operation is completed, the first cover 10 can be re-fixed to the second cover 20.

[0042] Thus, by utilizing the separate design of the first cover 10 and the second cover 20, the user can open the first cover 10 to directly clean the interior of the accommodating space 22, facilitating dust removal and improving dust removal efficiency and heat dissipation. Furthermore, when cleaning and dusting, the user only needs to disassemble the first cover 10; there is no need to additionally disassemble the heat dissipation component 300 or the entire air guide cover 100. This significantly simplifies maintenance operations, saves manpower, and reduces machine failures caused by human error, while still meeting the machine's heat dissipation and dust removal functions.

[0043] In some embodiments, the relative distribution direction of the first ventilation hole 11 and the second ventilation hole 21 is parallel to the airflow direction of the heat dissipation assembly 300. For example, the first ventilation hole 11 and the second ventilation hole 21 are distributed relative to each other in a vertical direction, that is, the first ventilation hole 11 and the second ventilation hole 21 are distributed vertically, and the airflow direction of the cooling fan 301 is parallel to the vertical direction. The vertical direction is the Z-axis direction shown in the figure. Thus, a heat dissipation airflow channel corresponding to the airflow of the cooling fan 301 can be formed between the first ventilation hole 11 and the second ventilation hole 21, accelerating the gas exchange rate and improving the heat dissipation effect.

[0044] It is understood that the directional descriptions in this application, such as "up" and "down," are explanatory descriptions based on the product's orientation in normal use scenarios, and are not limitations on the product's structure.

[0045] In some embodiments, the first ventilation holes 11 are formed on the periphery of the first cover 10. For example, the first cover 10 is generally rectangular, and the first cover 10 has a top surface and multiple side surfaces. Each side surface of the first cover 10 is provided with multiple first ventilation holes 11, and the top surface of the first cover 10 is not provided with any first ventilation holes 11.

[0046] Thus, during heat dissipation, external airflow can enter the accommodating space 22 through multiple first ventilation holes 11 on the side of the first cover 10, ensuring that the airflow can meet the heat dissipation requirements. At the same time, the top surface of the first cover 10 forms a shielding component above the second cover 20, preventing debris, dust, etc. from passing through the first cover 10 and entering the interior of the accommodating space 22 in the direction of gravity, reducing the accumulation of debris, dust, etc. inside the accommodating space 22, and improving heat dissipation performance.

[0047] In some embodiments, the upper end of the first cover 10 protrudes upward relative to the upper end of the chassis 200. For example, the upper end of the first cover 10 protrudes from the upper surface of the chassis 200, and each side of the protruding portion is provided with a first ventilation hole 11. This reduces the obstruction of the first ventilation holes 11 by the top of the chassis 200, further increasing the airflow.

[0048] In the example of this application, the first cover 10 includes a first baffle 12, a second baffle 13, a top plate 14 and two side plates 15, wherein the top plate 14 constitutes the top surface of the first cover 10, the first baffle 12 constitutes the back surface of the first cover 10, the second baffle 13 constitutes the front surface of the first cover 10, the two side plates 15 constitute the two sides of the first cover 10, the first baffle 12, the second baffle 13 and the two side plates 15 constitute the periphery of the first cover 10, and each of them is provided with a plurality of first ventilation holes 11.

[0049] Specifically, the top plate 14 is parallel to the horizontal direction and extends along the first direction. The first baffle 12 and the second baffle 13 are positioned opposite each other, located on opposite sides of the top plate 14 in the second direction, and both baffles are perpendicular to the top plate 14. Two side plates 15 are located at opposite ends of the top plate 14 in the first direction, and are perpendicular to the top plate 14. The height of the top plate 14 is higher than the upper surface of the chassis 200. The side plates 15 have notches 152 for accommodating the upper part of the chassis 200, and the second baffle 13 overlaps the upper surface of the chassis 200. An angle is formed between the first direction, the second direction, and the vertical direction. The first direction is the X-axis direction shown in the figure, and the second direction is the Y-axis direction shown in the figure.

[0050] In some embodiments, the first cover 10 and the second cover 20 are inserted into each other. Guide blocks 151 are respectively provided on both sides of the first cover 10, and the two guide blocks 151 are respectively positioned in a first direction with the second cover 20. For example, the guide blocks 151 are formed at the lower end of the side plate 15. The guide blocks 151 can be formed by bending the lower end of the side plate 15 away from the inner side of the first cover 10. The two guide blocks 151 are respectively attached to the two outer walls of the second cover 20 in the first direction to form a positioning fit. The connection between the guide block 151 and the side plate 15 abuts against the second cover 20 along the first direction, so that the guide block 151 and the second cover 20 can be positioned in the first direction.

[0051] When the first cover 10 is installed on the second cover 20, the guide block 151 can play a guiding role at the docking point of the first cover 10 and the second cover 20, guiding the first cover 10 and the second cover 20 to quickly align and improve assembly efficiency.

[0052] In the example of this application, the two guide blocks 151 are positioned from the outside of the mounting port 221. In other embodiments, the two guide blocks 151 may also be positioned from the inside of the mounting port 221. The two guide blocks 151 are respectively attached to the two inner walls of the second cover 20 in the first direction to form a positioning fit. This application does not limit this.

[0053] In some embodiments, the guide block 151 is provided with a mounting hole 153 for a fastener to pass through, and the guide block 151 is fixed to the second cover 20 by the fastener. For example, the fastener is a fixing screw, which passes through the mounting hole 153 and is threadedly connected to the second cover 20.

[0054] When it is necessary to detach the first cover 10 from the second cover 20, the fastener can be unscrewed from the mounting hole 153, and then the first cover 10 can be pulled out from the upper end of the second cover 20. When it is necessary to install the first cover 10 onto the second cover 20, the first cover 10 can be sleeved onto the upper end of the second cover 20, and then the first cover 10 and the second cover 20 can be fixed by the fastener.

[0055] In the example of this application, the guide block 151 and the second cover 20 are detachably fixed by bolting. In other embodiments, the guide block 151 and the second cover 20 can also be detachably fixed by snap-fit, interference fit, or other means. This application does not limit this.

[0056] In some embodiments, a positioning block 121 is provided at the lower end of the first cover 10. The positioning block 121 is inserted vertically into the mounting opening 221 and abuts against the inner side of the mounting opening 221 in the second direction. Thus, the positioning block 121 and the second cover 20 form a positioning fit and an interference fit in the second direction, improving the tightness of the fit at the junction of the first cover 10 and the second cover 20. When it is necessary to install the first cover 10 onto the second cover 20, the positioning block 121 can be directly inserted into the inner side of the second cover 20 to achieve positioning of the first cover 10 and the second cover 20 in the second direction, improving installation efficiency.

[0057] In some embodiments, the second cover 20 is provided with a positioning port 232, which allows the positioning plug 121 to be inserted vertically, and the positioning plug 121 is confined in the positioning port 232 along the first direction. In this way, the second cover 20 forms a positioning engagement with the positioning plug 121 in the first direction through the positioning port 232, thereby achieving a positioning effect in multiple directions.

[0058] In some embodiments, a positioning insert 121 is formed on the lower side of the first baffle 12, and the connection between the positioning insert 121 and the first baffle 12 is bent so that the positioning insert 121 is inclined toward the inner side of the first cover 10. In this way, the positioning insert 121 can be inserted more easily.

[0059] In some embodiments, there are multiple positioning blocks 121, which are spaced apart along the length of the first baffle 12. In this way, the multiple positioning blocks 121 can simultaneously form positioning engagements with the second cover 20 at multiple positions of the first cover 10, thereby improving positioning stability.

[0060] In some embodiments, the second baffle 13 is detachably connected to the chassis 200. For example, a fixing block 131 is provided on the lower side of the second baffle 13, and the fixing block 131 is bolted to the upper end of the chassis 200 by fixing screws. Thus, fixing the second baffle 13 to the chassis 200 improves the installation stability of the first cover 10.

[0061] When it is necessary to remove the first cover 10 from the second cover 20, the fastener can be unscrewed from the mounting hole 153 and the fixing block 131 can be removed from the chassis 200. Then the first cover 10 can be pulled out from the top of the second cover 20.

[0062] When installing the first cover 10 onto the second cover 20, the first cover 10 can be inserted into the upper part of the second cover 20, and then the front of the first cover 10 can be fixed to the chassis 200 using fixing screws, while the side of the first cover 10 can be fixed to the second cover 20. This avoids the need for screws on the back of the first cover 10, ensuring the aesthetics and harmony of the overall appearance of the equipment. Furthermore, the guiding and positioning designs of the positioning block 121 and guide block 151 can guide the first cover 10 into the second cover 20 and align it with the second cover 20, facilitating installation. Additionally, after installation, the interference fit between the first cover 10 and the second cover 20 can improve overall strength and durability.

[0063] In the example of this application, the second baffle 13 and the chassis 200 are detachably fixed by bolting. In other embodiments, the second baffle 13 and the chassis 200 can also be detachably fixed by snap-fit, interference fit, or other means. This application does not impose any restrictions on this.

[0064] In some embodiments, the second ventilation hole 21 is formed on the bottom surface of the second cover 20. For example, the second cover 20 is generally rectangular, and has a bottom surface and multiple side surfaces. The top surface of the second cover 20 is provided with multiple second ventilation holes 21, and each side surface of the second cover 20 is not provided with a second ventilation hole 21.

[0065] Thus, during heat dissipation, external airflow can be blown out of the accommodating space 22 through multiple second ventilation holes 21 on the bottom surface of the second cover 20, ensuring that the airflow can meet the heat dissipation requirements. At the same time, the upper part of the second cover 20 is not provided with ventilation holes, which can prevent debris, dust and other objects from entering the interior of the second cover 20 in the direction of gravity, reduce the accumulation of debris, dust and other objects in the accommodating space 22, and improve heat dissipation performance.

[0066] In the example of this application, the second cover 20 includes a cover plate 23, a bottom plate 24, and two upright plates 25, wherein the cover plate 23, the bottom plate 24, and the two upright plates 25 enclose an accommodating space 22. The cover plate 23 is correspondingly disposed to the first baffle 12, and the two upright plates 25 are respectively disposed to the two side plates 15. The bottom plate 24 constitutes the bottom surface of the second cover 20, the cover plate 23 constitutes the back surface of the second cover 20, and the upright plates 25 constitute the sides surface of the second cover 20. The bottom plate 24 has a plurality of second ventilation holes 21.

[0067] In some embodiments, the second cover 20 is provided with a guide flange 231, which is inserted into the first cover 10 in the vertical direction and abuts against the inner side of the first cover 10 in the second direction. The guide flange 231 has a positioning port 232 for the positioning block 121 to be inserted into, and the positioning block 121 is limited to the positioning port 232 in the first direction.

[0068] Thus, the guide protrusion 231 and the first cover 10 form a positioning fit and interference fit in the second direction, improving the tightness of the fit at the junction of the first cover 10 and the second cover 20. Furthermore, the guide protrusion 231 forms a positioning fit with the positioning insert 121 in the first direction through the positioning port 232, further improving the positioning effect.

[0069] In some embodiments, a guide flange 231 is formed on the upper side of the cover plate 23, and the connection between the guide flange 231 and the cover plate 23 is bent so that the guide flange 231 is inclined toward the inner side of the second cover 20. In this way, the guide flange 231 can be more easily inserted into the inner side of the second cover 20, and at the same time, it can guide the docking between the first cover 10 and the second cover 20.

[0070] In some embodiments, the second cover 20 is detachably connected to the chassis 200. For example, mounting blocks 26 are provided on the sides of the upright plate 25 and the bottom plate 24, and the mounting blocks 26 are bolted to the back of the chassis 200. This detachable connection between the second cover 20 and the chassis 200 facilitates the user opening the second cover 20 to clean or maintain the heat dissipation assembly 300 or the functional devices 400.

[0071] In the example of this application, the upright plate 25 and the chassis 200 are detachably fixed by bolting. In other embodiments, the upright plate 25 and the chassis 200 can also be detachably fixed by snap-fit, interference fit, or other means. This application does not impose any restrictions on this.

[0072] In some embodiments, the mounting bracket 302 is a pull-out bracket that can slide relative to the chassis 200 along a first direction. A pull-out opening 251 is provided on the side of the second cover 20, and part of the mounting bracket 302 is exposed in the pull-out opening 251.

[0073] Thus, when the user needs to clean the heat dissipation component 300, the mounting bracket 302 can be pulled out from the pull-out port 251 along the second direction so that the heat dissipation component 300 is exposed on the outside of the second cover 20. After cleaning, the mounting bracket 302 can be pushed back into the second cover 20 from the pull-out port 251 along the second direction.

[0074] like Figure 1 and Figure 2 As shown in the illustration, this application also provides a photovoltaic device 1000. The photovoltaic device 1000 can be an inverter, and includes a chassis 200, a heat dissipation assembly 300, functional components 400, and an air guide shroud 100. The heat dissipation assembly 300 and the functional components 400 are disposed on the outside of the chassis 200. The air guide shroud 100 is connected to the chassis 200 and covers the heat dissipation assembly 300 and the functional components 400. For example, the chassis 200 has a front and a back, and both the heat dissipation assembly 300 and the functional components 400 are disposed on the back of the chassis 200. The heat dissipation assembly 300 can be a combination of a cooling fan 301 and a mounting bracket 302. The functional components 400 can be a heat sink, an inductor 402, a heat exchanger 403, etc.

[0075] The implementation principle and beneficial effects of the photovoltaic equipment 1000 provided in this application can be found in the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0076] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments described above should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
