Description

Technical Field

[0001] This utility model relates to the field of electrical product technology, and in particular to a cooling fan mounting structure and an inverter. Background Technology

[0002] In server racks, energy storage inverters (such as 200kW-class equipment), or wall-mounted electrical cabinets, the equipment is usually densely arranged. To ensure that the equipment operates stably within a safe temperature range, the fan assembly needs to be designed by comprehensively considering factors such as heat dissipation requirements and space layout.

[0003] In the existing technology, a fan structure that can only be pulled out from one side is set on the side of the cabinet. When the fan structure is pulled out from one side, a large operating space needs to be reserved on that side. Due to the dense arrangement of equipment and insufficient space, it is often necessary to disassemble the surrounding modules before the fan structure can be pulled out, which is time-consuming and prone to failure.

[0004] Therefore, there is an urgent need to provide a cooling fan mounting structure and inverter to solve the problem that the surrounding modules need to be disassembled to provide operating space before the single-sided pull-out fan structure can be pulled out. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling fan mounting structure and inverter to solve the problem that the surrounding modules need to be disassembled to provide operating space before the single-sided pull-out fan structure is pulled out.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides an installation structure for a cooling fan, including a fan rail, a fan assembly, and a sealing plate. The fan rail is configured to be fixed to the inverter housing. The fan assembly includes two fan groups, which are slidably engaged with the fan rail. The sealing plate is detachably connected to both ends of the fan rail. Each sealing plate abuts against the end face of the corresponding fan group to prevent the fan group from detaching along the fan rail.

[0008] As an optional technical solution for the installation structure of a cooling fan, the fan assembly includes a fixing component, a locking accessory, a fan, and an auxiliary component. The fan is detachably fixed to the fixing component via the locking accessory, and the fixing component slides with the fan guide rail via the auxiliary component.

[0009] As an optional technical solution for the installation structure of a cooling fan, the fixing component includes a main board and a mounting plate. The mounting plates are vertically connected to opposite ends of the main board, and the two mounting plates are respectively provided with the auxiliary component. The fan is fixed to the main board by the locking accessory and placed between the two mounting plates.

[0010] As an optional technical solution for the installation structure of a cooling fan, the auxiliary component is fixed on the side of each of the two mounting plates that are close to each other.

[0011] As an optional technical solution for the installation structure of a cooling fan, the two auxiliary components of each fan assembly are symmetrically arranged.

[0012] As an optional technical solution for the installation structure of a cooling fan, the fan is provided in multiple ways, the locking accessory is provided with mounting holes corresponding to the fan, the mounting holes are spaced apart along the sliding direction of the fan assembly, and the fan passes through the mounting holes and is partially clamped and fixed between the locking accessory and the fixing member.

[0013] As an optional technical solution for the installation structure of a cooling fan, the auxiliary components of both fan assemblies are provided with elastic positioning parts, and the fan guide rail is provided with positioning parts corresponding to the elastic positioning parts; when the fan assembly is pushed into the fan guide rail, the elastic positioning part of the fan assembly engages with the positioning part; when the fan assembly is pulled out from the fan guide rail, the elastic positioning part disengages from the positioning part.

[0014] As an optional technical solution for the installation structure of a cooling fan, the auxiliary component includes a main mounting plate and a sliding plate connected to the main mounting plate. The main mounting plate is fixed to the fixing member, and the fixing member slides with the fan guide rail through the sliding plate. The end of the sliding plate is bent toward the direction close to the fan guide rail to serve as the elastic positioning part, and the positioning part is a groove.

[0015] As an optional technical solution for the installation structure of a cooling fan, it also includes a first fastener and a second fastener. The sealing plate is fixed to the fan rail by the first fastener and to the fan assembly by the second fastener. The first fastener and the second fastener are located at opposite corners of the sealing plate.

[0016] This utility model provides an inverter, including a housing and the aforementioned mounting structure for the cooling fan.

[0017] Beneficial effects:

[0018] This utility model provides an installation structure for a cooling fan, including a fan rail, a fan assembly, and a sealing plate. The fan rail is configured to be fixed to the inverter housing. The fan assembly includes two fan groups, each slidably engaged with the fan rail. Sealing plates are detachably connected to both ends of the fan rail, with each sealing plate abutting against the end face of the corresponding fan group to prevent the fan group from detaching along the fan rail. The fan rail is fixed to the inverter housing. During installation, the two fan groups are pushed into the fan rail from both sides, slidingly installed at different positions on the fan rail. Finally, a sealing plate is installed at the end of the two fan groups furthest from each other, abutting against the end face of the corresponding fan group to prevent the fan group from detaching along the fan rail. After removing the sealing plate, the two fan groups can be pulled out from both sides for fan maintenance. This bidirectional pull-out operation replaces the existing single-sided pull-out method. The bidirectional pull-out requires less space on one side than the single-sided pull-out operation space, eliminating the need to disassemble surrounding modules before extraction, saving operation time and preventing malfunctions caused by disassembling surrounding modules.

[0019] This invention provides an inverter, including a housing and the aforementioned mounting structure for the cooling fan. Using this mounting structure, the space required for each side of the dual-sided pull-out mechanism is reduced, making maintenance and operation more convenient. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] like Figures 1 to 6 As shown, this embodiment provides a cooling fan mounting structure, including a fan rail 1, a fan assembly 2, and a sealing plate 3. The fan rail 1 is configured to be fixed to the inverter housing. The fan assembly 2 includes two fan groups 20, which are slidably engaged with the fan rail 1. The two ends of the fan rail 1 are detachably connected to the sealing plate 3. Each sealing plate 3 abuts against the end face of the corresponding fan group 20 to restrict the fan group 20 from coming off the fan rail 1.

[0043] The fan rail 1 is fixed to the inverter housing. During installation, the two fan groups 20 are pushed into the fan rail 1 from both sides. The two fan groups 20 are slidably installed at different positions on the fan rail 1. Finally, the sealing plate 3 is installed at the ends of the two fan groups 20 that are far apart from each other. The sealing plate 3 abuts against the end face of the corresponding fan group 20 to prevent the fan group 20 from coming out along the fan rail 1. After removing the sealing plate 3, the two fan groups 20 can be pulled out from both sides to perform fan maintenance. The bidirectional pull-out operation replaces the existing single-sided pull-out method of the fan structure. The space required for bidirectional pull-out is smaller than that for single-sided pull-out operation. Therefore, there is no need to disassemble the surrounding modules before pulling out, which can save operation time and prevent failure caused by disassembling the surrounding modules.

[0044] Specifically, the fan assembly 20 includes a fixing member 21, a locking accessory 22, a fan 23, and an auxiliary member 24. The fan 23 is detachably fixed to the fixing member 21 via the locking accessory 22, and the fixing member 21 is slidably engaged with the fan guide rail 1 via the auxiliary member 24. The sliding engagement between the fixing member 21 and the fan guide rail 1, along with the detachable fixing of the fan 23 to the fixing member 21 using the locking accessory 22, ensures the proper installation position of the fan 23 and allows for removal of the fan 23 from the fixing member 21 without disassembling the entire fan assembly 20.

[0045] See Figure 1 Multiple fans 23 are provided, and the locking accessory 22 has mounting holes 221 corresponding to the fans 23. The mounting holes 221 are spaced apart along the sliding direction of the fan assembly 20. The fans 23 pass through the mounting holes 221 and are partially clamped and fixed between the locking accessory 22 and the fixing member 21. Multiple fans 23 are inserted into the corresponding mounting holes 221 of the locking accessory 22, and are partially clamped and fixed between the locking accessory 22 and the fixing member 21. The fans 23 can be installed in different positions according to the actual heat dissipation requirements, so as to efficiently dissipate heat for different components of the inverter, and also keep the fans 23 firmly fixed.

[0046] In this embodiment, each fan group 20 includes three fans 23 spaced apart, and the mounting holes 221 on the locking accessory 22 are also provided accordingly; the locking accessory 22 is fixed to the fixing member 21 by screws.

[0047] Furthermore, the fixing component 21 includes a main board 211 and a mounting plate 212. The mounting plates 212 are vertically connected to opposite ends of the main board 211. The two mounting plates 212 are respectively provided with auxiliary components 24. The fan 23 is fixed to the main board 211 by a locking accessory 22 and is placed between the two mounting plates 212.

[0048] The mainboard 211 and the two mounting plates 212 form a stable frame structure perpendicularly, providing stable support for the fan 23. The two mounting plates 212 slide with the fan rail 1 through the auxiliary parts 24, which helps to prevent the fan assembly 20 from shaking, shifting, or even derailing. The fan 23 and the locking accessory 22 are arranged between the two auxiliary parts 24 to ensure the uniformity of force, making the fan assembly 20 slide more smoothly relative to the fan rail 1.

[0049] In this embodiment, the fixing member 21 is an integral bent structure; the auxiliary member 24 and the fan 23 are located on the same side of the motherboard 211; placing the auxiliary member 24 and the fan 23 on the same side of the motherboard 211 helps to form effective air circulation and improve heat dissipation.

[0050] Optionally, auxiliary components 24 are fixed to the sides of the two mounting plates 212 that are close to each other. By placing the auxiliary components 24 on the sides of the two mounting plates 212 that are close to each other, i.e., both auxiliary components 24 are located between the two mounting plates 212, the structure is compact and helps to enhance the overall stability of the cooling fan structure.

[0051] In this embodiment, the two auxiliary components 24 of each fan assembly 20 are symmetrically arranged. The symmetrical auxiliary components 24 can evenly distribute the frictional force generated when the fan assembly 20 contacts the fan guide rail 1 during the sliding process, avoiding jamming or displacement due to uneven force, making the sliding process more stable, and at the same time providing an accurate guide path for the fan assembly 20, which is convenient for installation and alignment, and ensures that the fan assembly 20 slides along the predetermined direction of the fan guide rail 1.

[0052] See Figures 1 to 3 , Figure 7 and Figure 8 The mounting structure of the cooling fan also includes a first fastener and a second fastener. The cover plate 3 is fixed to the fan rail 1 by the first fastener and to the fan assembly 20 by the second fastener. The first fastener and the second fastener are located at opposite corners of the cover plate 3.

[0053] The sealing plate 3 is fixed to the fan assembly 20 and the fan rail 1 by fasteners. The first and second fasteners set diagonally can make the sealing plate 3 more evenly stressed, avoid stress concentration on one side that may cause deformation or cracking, effectively counteract the torque generated by vibration, and reduce the risk of loosening.

[0054] In this embodiment, the two fan groups 20 are respectively the first fan group 20a and the second fan group 20b, and the sliding directions of the first fan group 20a and the second fan group 20b are coincident; the two sealing plates 3 are respectively the first sealing plate 3a and the second sealing plate 3b, the first sealing plate 3a is fixed to the fan guide rail 1 and the first fan group 20a, and the second sealing plate 3b is fixed to the fan guide rail 1 and the second fan group 20b; the first sealing plate 3a and the second sealing plate 3b are each provided with a first fixing hole 31 and a second fixing hole 32, the first fixing hole 31 is used to install a first fastener, and the second fixing hole 32 is used to install a second fastener; the sealing plate 3 is fixed to the fan guide rail 1 and the fixing member 21 of the corresponding fan group 20, and the first fastener and the second fastener are both screws.

[0055] Furthermore, the auxiliary parts 24 of both fan groups 20 are provided with elastic positioning parts 241, and the fan guide rail 1 is provided with positioning parts 10 corresponding to the elastic positioning parts 241; when the fan group 20 is pushed into the fan guide rail 1, the elastic positioning parts 241 of the fan group 20 engage with the positioning parts 10; when the fan group 20 is pulled out from the fan guide rail 1, the elastic positioning parts 241 disengage from the positioning parts 10.

[0056] An elastic positioning part 241 is provided on the auxiliary part 24 of the two fan groups 20, and a positioning part 10 is provided on the fan guide rail 1. When the fan group 20 is pushed into the fan guide rail 1, the positioning part 10 and the elastic positioning part 241 automatically engage and cooperate to position the fan group 20, thereby ensuring that the fan group 20 is stably installed in a specific position and avoiding collisions or accidental dislodgement due to loosening. When the fan group 20 is pulled out, the elastic positioning part 241 is pressed and released from the positioning part 10. It can be quickly engaged or disengaged without additional operation, making the operation more convenient.

[0057] In this embodiment, each auxiliary component 24 of the first fan group 20a and the second fan group 20b is provided with an elastic positioning part 241; the upper and lower sides of the fan guide rail 1 are provided with positioning parts 10, and the two positioning parts 10 located on the same side are the first positioning part 11 and the second positioning part 12, the first positioning part 11 is used to engage with the elastic positioning part 241 of the first fan group 20a, and the second positioning part 12 is used to engage with the elastic positioning part 241 of the second fan group 20b.

[0058] See Figure 2 , Figure 3 , Figure 9 and Figure 10 The auxiliary component 24 includes a main mounting plate 242 and a sliding plate 243 connected to the main mounting plate 242. The main mounting plate 242 is fixed to the fixing member 21. The fixing member 21 slides with the fan guide rail 1 through the sliding plate 243. The end of the sliding plate 243 is bent toward the direction close to the fan guide rail 1 to serve as an elastic positioning part 241. The positioning part 10 is a groove.

[0059] The bent end of the sliding plate 243 serves as the elastic positioning part 241, and a groove is designed as the positioning part 10. The elastic deformation of the elastic positioning part 241 itself achieves an elastic snap-fit ​​engagement with the groove in the fan rail 1, eliminating the need for additional elastic elements. In this embodiment, the first positioning part 11 and the second positioning part 12 have the same structure and are both grooves. In other embodiments, other elastic elements and snap-fit ​​structures can be used to replace the elastic positioning part 241 and the positioning part 10, enabling an elastic snap-fit ​​engagement when the fan assembly 20 is pushed into the fan rail 1 and releasing the engagement when the fan assembly 20 is pushed out.

[0060] In this embodiment, the plane of the main mounting piece 242 is parallel to the plane of the mounting plate 212 of the fixing member 21, and the plane of the sliding piece 243 is perpendicular to the plane of the main mounting piece 242. The main mounting piece 242 is attached to and fixed to the mounting plate 212 by riveting. The auxiliary member 24 is an integral bent structure with no connection gap, which can effectively resist vibration and ensure the stability of the fan assembly 20.

[0061] In this embodiment, both ends of the auxiliary component 24 are bent with elastic positioning portions 241; during installation, there is no need to distinguish the installation direction of the auxiliary component 24, and the elastic positioning portion 241 at either end of the auxiliary component 24 can be elastically engaged with the fan guide rail 1.

[0062] In this embodiment, the lock accessory 22 is provided with a cable tie for fixing the fan cable; the main board 211 of the fixing member 21 is provided with a handle structure for manual gripping and pulling.

[0063] This embodiment also provides an inverter, including a housing and the aforementioned cooling fan mounting structure. The following describes the specific installation and usage process of the dual-sided exhaust cooling fan structure:

[0064] See Figures 2 to 4 as well as Figure 11 First, fix the fan rail 1 to the bottom frame side of the inverter housing. Push the first fan group 20a inward along the fan rail 1 from one side until the elastic positioning part 241 of the first fan group 20a engages with the first positioning part 11. Push the second fan group 20b inward along the fan rail 1 from the other side until the elastic positioning part 241 of the second fan group 20b engages with the second positioning part 12. At this point, the first fan group 20a and the second fan group 20b are installed in place and cannot be pushed further. The end of the first fan group 20a and the second fan group 20b that is close to each other is called the inner end and the end that is far away from each other is called the outer end.

[0065] See Figure 12 and Figure 13The first sealing plate 3a is fixed to the outer end of the first fan group 20a and the fan rail 1, and the second sealing plate 3b is fixed to the outer end of the second fan group 20b and the fan rail 1, thereby fixing the first fan group 20a and the second fan group 20b to the bottom frame of the inverter box. At this time, the installation is completed.

[0066] See Figure 14 If maintenance of fan assembly 2 is required, the first sealing plate 3a and the second sealing plate 3b can be removed, and the first fan group 20a and the second fan group 20b can be pulled out from both sides respectively.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
