Description

Technical Field

[0001] The utility model relates to the fields of photovoltaics and energy storage, and in particular to a dust-proof heat dissipation structure and a photoelectric storage device containing the same. Background Art

[0002] As solar-powered storage equipment ages, maintenance issues arise. Dust accumulates over time, impacting the functionality of components and cooling, ultimately affecting the equipment's normal operation and use. Cleaning and preventing dust accumulation has always been a maintenance pain point for solar-powered storage equipment. Designing a dust prevention solution that facilitates routine maintenance for customers and customer service personnel has become a key priority.

[0003] At present, the dust and heat dissipation of optical storage equipment are mainly achieved by fans, dust nets and dust covers. However, the reversing fans can only achieve a small amount of dust absorption and dust removal. Most dust, lint and other debris will still enter through the air inlet. Currently, most air inlets use a fixed dust-proof design, and most of the openings at the air inlet do not play a role in dust prevention and rectification.

[0004] Currently, most optical storage equipment still uses an integrated dustproof design. The fan dustproof and heat dissipation structure is a fixed structure, which is difficult to disassemble and inconvenient for future maintenance. Dust covers are mainly integrated designs. Maintenance requires disassembling the large dustproof and heat dissipation structure and then cleaning the equipment. This operation is difficult, requires high professionalism, and is less user-friendly. Utility Model Content

[0036] See also Figures 1 to 11 The embodiment of the present invention provides a dust-proof heat dissipation structure, comprising a dust cover 10, a top dust-proof mesh plate 20 detachably arranged at the upper end of the dust cover 10, a support member 30 arranged at the upper end of the top dust-proof mesh plate 20, and a pull-out fan dust-proof assembly 40 arranged at the lower end of the dust cover 10, the pull-out fan dust-proof assembly 40 comprising a pull-out bottom dust-proof mesh plate 41 arranged at the bottom of the dust cover 10, a guide rail 42 arranged at the upper end of the pull-out bottom dust-proof mesh plate 41, a bracket 43 arranged at the upper end of the guide rail 42, and a plurality of fans 44 arranged at the upper end of the bracket 43, the lower end of the bracket 43 is slidably connected to the guide rail 42, both sides of the guide rail 42 are detachably connected to the dust cover 10, the lower end of the guide rail 42 is slidably connected to the pull-out bottom dust-proof mesh plate 41, the support member 30, the dust cover 10 and the optical storage device 60 are detachably connected.

[0037] The above-mentioned dustproof and heat dissipation structure improves the convenience of disassembly and assembly of the dustproof and heat dissipation structure by detachably connecting the support member 30, the dust cover 40 and the optical storage device 60. When it is necessary to disassemble or clean the fan 44, it is only necessary to pull the bracket 43 to drive the bracket 43 to slide on the guide rail 42 until all fans 44 are moved outside the dust cover 10, and then the fan 44 can be disassembled or cleaned very conveniently.

[0038] In one embodiment of the present invention, an outer side of the guide rail 42 is provided with an inwardly concave bend 421 , and a position of the bracket 43 corresponding to the inwardly concave bend 421 is provided with a limit block 431 .

[0039] In one embodiment, the pull-out fan dustproof assembly 40 primarily consists of two brackets 43 (fan bracket 1 432 and fan bracket 2 433) and five fans 44 (in other embodiments, the number of fans can be other values, such as 3, 7, etc., and can be designed according to actual needs). The slide rails of fan bracket 1 432 and fan bracket 2 433 are composed of "U"-shaped bends on both sides of sheet metal, which match the tolerances of guide rail 42 to form "U"-shaped groove guide rails, realizing the pull-out function of the pull-out fan dustproof assembly 40. Fans 44 are reversible fans, and the arrangement of fans 44 adopts a design with increasing spacing. At the same time, the fans 44 are arranged more compactly near the pull-out position to ensure smooth and stable pull-out of fans 44. The fan bracket 1 432 and the fan bracket 2 433 in the bracket 43 are connected by a hinge structure 434, which can be compatible with more installation environments. The hinge structure 434 mainly utilizes a sheet metal step-type arched inward folding opening design to connect the fan bracket 1 432 and the fan bracket 2 433 by screws. At the same time, the screws also serve as the hinge axis. This design saves costs, has a large design margin, and is more compatible. The inward-concave bend 421 of the overall pull-out structure is cut inward near the pull-out position, and the folded edge is designed with a "U"-shaped opening to play a limiting role. At the same time, it can also be screwed to the bracket 43 and the guide rail 42. The inward-concave bend 421 also makes it easier for the fingers to pull out the pull-out fan dustproof assembly 40. An arched clip 435 for installing the wire terminal of the fan 44 is designed near the pull-out outlet. The arched clip 435 matches the fan wire terminal limit slot, which can better organize the fan 44 output line and also facilitate the installation and maintenance of the fan line.

[0040] In one embodiment, in one embodiment of the present invention, the cross-section of the support member 30 is L-shaped, and one end of the support member 30 is connected to the top dustproof screen 20, and the other end of the support member 30 is connected to the optical storage device 60, so that the upper end of the dustproof heat dissipation structure is fixedly connected to the optical storage device 60 through the support member 30. Specifically, the six through holes 22 on the top dustproof screen 20 cooperate with the three-in-one cross screws 23 to install the top dustproof screen 20 on the dust cover 10. The dustproof air outlet of the top dustproof screen 20 is an array of regular mesh holes, and the design range (contour) of the array of regular mesh holes is rectangular. The dustproof air outlet is located at the lower right part of the top dustproof screen 20 and forms an integral air duct system with the bottom pull-out fan dustproof assembly 40.

[0041] In one embodiment of the present invention, the number of through holes is 4, 8 or other numbers.

[0042] In one embodiment of the present invention, a reinforcement plate 21 is provided at the front end of the top dustproof screen plate 20, and the cross-section of the reinforcement plate 21 is L-shaped. Through the above structural design, the strength of the entire top dustproof screen plate 20 can be enhanced.

[0043] In one embodiment of the present invention, side air outlets 11 are provided on both sides of the dust cover 10, front air outlets 12 are provided at the front end of the dust cover 10, and a plurality of inward-folding air outlets 13 are also provided at the front end of the dust cover 10, and a plurality of upward-slanted folded air outlets 14 are also provided on the lower side of the plurality of inward-folding air outlets 13.

[0044] Specifically, the dust cover 10 is overall in a "U" shape, with the top and bottom being hollow designs, which not only leaves installation space for the top dust screen 20, the dust cover 10, the bracket 43, and the guide rail 42, but also facilitates deep cleaning and maintenance of the components of the optical storage device 60 protected by the dust cover.

[0045] In one embodiment, the front air outlet 12 and the side air outlet 11 of the dust cover 10 adopt an array regular dense hole design (the mesh shape is not limited, such as rectangular, elliptical, circular, square, hexagonal, etc.), and the dense hole opening range (contour) is rectangular. The dust cover 10 is an important part of the overall air duct system. The upper edge of the dust cover is riveted with a stainless steel circular rivet nut, which is mainly used to connect the top dustproof mesh plate 20. In order to better dissipate heat, the front adopts a "louver" type inward folding air outlet 13 design, which has a good air duct rectification effect. At the same time, in order to prevent too much dust from entering the inward folding air outlet 13, an upward inclined folding edge air outlet 14 is designed below the position of the inward folding air outlet 13, so that the dust and debris entering the inward folding air outlet 13 can be naturally blown out along with the air duct outlet system.

[0046] In one embodiment of the present invention, the guide rail 42 includes a guide rail body 422, upper external guide rails 423 provided on both sides of the upper end of the guide rail body 422, and lower external guide rails 424 provided on both sides of the lower end of the guide rail body 422. The upper external guide rails 423 are connected to the bracket 43 in a pull-out sliding manner, and the lower external guide rails 424 are connected to the pull-out bottom dustproof screen 41 in a pull-out sliding manner. Specifically, the guide rail 42 is a component-type design, consisting of a guide rail body 422, an upper external guide rail 423, a lower external guide rail 424, and a riveted limiting fixing member 425. The upper external guide rails 423 and the lower external guide rails 424 are connected to the guide rail body 422 using a riveting process or screws, mainly to provide a pull-out guide rail for the pull-out bottom dustproof screen 41. The upper external guide rail 423 and the lower external guide rail 424 are in a "U" shape as a whole, and are designed with an ear-type limiter and a snap-fit function with the convex bump 413 of the pull-out bottom dust screen 41. By designing the upper external guide rail 423 and the lower external guide rail 424, the pull-out bottom dust screen 41 can be conveniently, quickly and smoothly disassembled and maintained. The tail of the guide rail 42 forms a snap-fit design with the fan bracket 432 through the trapezoidal guide bend 426 and the concave bend 421, thereby achieving the functions of guiding, limiting and fixing the pull-out fan dust screen assembly 40. The rivet limit fixing part 425 is installed on the guide rail body 422 by rivet or screw connection, and is in the shape of a "common" as a whole. The rivet limit fixing part 425 is riveted with a stainless steel round rivet nut to fix the pull-out fan dust screen assembly 40, and two rivet nut columns are riveted to fix the pull-out bottom dust screen 41. The guide rail body 422 is designed with an anti-cut hand curling design at the hollow position of the pull-out outlet, ensuring the convenience and safety of pulling.

[0047] In one embodiment of the present invention, a side dust cover 50 is provided at a position corresponding to the pull-out end of the pull-out fan dust shield assembly and is detachably connected to the dust cover 10. The guide rail body 422 is designed with snap-on slots for mounting the side dust cover 50. The bottom of the side dust cover 50 is extended to shield the guide rail body 422 at the hollowed-out position of the pull-out outlet, thereby ensuring the integrity of the air duct system.

[0048] In one embodiment of the present invention, please refer to Figure 12 The guide rail 42 includes a guide rail body 422 and bent lugs 427 provided at the upper and lower edges of the guide rail body 422. A bent lug-type intermittent guide rail (bent lug 427) extends from the guide rail body 422. The lug interval distance is designed to bend a guide rail 428 from sheet metal to match the lug tolerance. This design is more cost-effective, more portable, and easier to assemble than an external guide rail, but requires higher machining accuracy.

[0049] In other embodiments of the present invention, the guide rail 42 can eliminate the pull-out bottom dustproof mesh plate 41, and directly design an array of regular dense holes matching the arrangement of the fan 44 on the guide rail body 422. Compared with the first two solutions, it is more cost-effective and has greater heat dissipation, dustproof and rectification effects. It is suitable for scenarios where there is a large margin of space for the installation of dustproof solutions.

[0050] In one embodiment of the present invention, the pull-out bottom dustproof mesh plate 41 is mainly composed of a dustproof mesh frame 1 410 and a dustproof mesh frame 2 411. The segmented pull-out design is compatible with a variety of installation environments and can be adjusted in segments according to the installation space. The dustproof mesh frame 1 410 and the dustproof mesh frame 2 411 are mainly connected together by screws and riveted nut columns. The screw arrangement design adopts a parallelogram arrangement, which increases the fixing area of the screws and improves the reliability and stability of the connection. The second dustproof mesh frame 411 extends out of the bent arch 415 and has a hole, and the pull-out bottom dustproof mesh plate 41 can be fixed to the bracket 43 and the guide rail 42 with screws. Two convex bumps 413 are designed at the tail of the dustproof mesh frame 1 410. The two convex bumps 413 cooperate with the bending of the guide rail 42 to form a buckle, so that the pull-out bottom dustproof mesh plate 41 is fixed more stably. The pull-out bottom dustproof mesh plate 41 as a whole matches the fan 44 design array regular dense hole design, which plays the role of air outlet and rectification. The hand position of the dustproof mesh frame 1 410 is designed with an anti-cut hand curled edge 414. The edges of the dustproof mesh frame 1 410 and the dustproof mesh frame 2 411 both adopt a "U"-shaped two-bend design to match the slide rail of the guide rail 42. The overall design of the chamfered guide structure makes the overall pulling more stable and smooth.

[0051] Overall installation method, such as Figure 13 As shown: one end of the support member 30 is fixed on the optical storage device 60 that needs heat dissipation and dust prevention, the top dustproof screen 20 is fixed on the dust cover 10 and the support member 30, one end of the guide rail 42 is fixed on the optical storage device 60 that needs heat dissipation and dust prevention, and the other end is used to fix the dust cover 10, and the pull-out bottom dustproof screen 41 is fixed on the dust cover 10. Figure 5 The side pull-out method shown is installed on the guide rail 42, and the bracket 43 and the guide rail 42 are connected as shown. Figure 3 The side pull-out method shown is installed on the guide rail 42. Then the side dust cover plate 50 is installed on the slot of the guide rail 42 and fixed to the dust cover 10 with screws.

[0052] In one embodiment, a plurality of mounting holes are provided on the side of the dust cover 10 , and the dust cover 10 can be fixed to the optical storage device by fasteners such as screws during installation.

[0053] In one embodiment, the air duct system of the overall dust-proof solution is configured such that the fan 44 blows air in a forward-directed upward direction, and the air is blown out through the inward-folding air outlet 13, the front air outlet 12, and the side air outlet 11 of the dust cover 10. The air is also blown out from the regular dense hole positions of the top dust-proof mesh plate 20. The runoff area of the entire air duct system is large, and the heat dissipation area is large, thereby improving the heat dissipation effect. At the same time, it also has a certain dust removal effect. The air duct system is reasonably designed, stable and reliable.

[0054] The present invention also provides a light storage device 60, comprising the above-mentioned dustproof and heat dissipation structure, wherein the support member 30 and the dust cover 10 in the dustproof and heat dissipation structure are detachably connected to the heat dissipation area of the light storage device through fasteners (screws).

[0055] When the optical storage device needs to be disassembled or cleaned, the bracket 43 only needs to be pulled to drive the bracket 43 to slide on the guide rail 42 until all fans 44 are moved outside the dust cover 10, so that the fans 44 can be disassembled or cleaned very conveniently.

[0056] In one embodiment, the dust cover 10 adopts a hollow design, and the top dust screen 20 is removable. The fan 44 in the bottom pull-out fan dust screen assembly 40 and the pull-out bottom dust screen 41 are both removable. By removing the top and bottom, you can perform deep cleaning and maintenance of the components of the optical storage equipment protected by the dust cover 10 from top to bottom in the loaded and running state.

[0057] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
