Description

Technical Field

[0001] This invention relates to the field of server rack technology, and more specifically to a detachable server rack with cable management functionality. Background Technology

[0002] As a core component of data center infrastructure, the structural design of server racks directly affects the stability of equipment operation, ease of maintenance, and space utilization. With the rapid development of cloud computing and edge computing, modern data centers are placing higher demands on server racks, especially in terms of modular design, cable management, and heat dissipation efficiency.

[0003] Traditional server rack frames typically employ a monolithic welded structure. While this design offers structural stability, it suffers from several significant drawbacks: monolithic racks are bulky, resulting in high transportation costs and difficulty adapting to varying installation requirements across different locations; the handling and installation of large racks are particularly challenging in confined spaces or high-rise buildings. Furthermore, existing racks lack effective cable management systems, leading to a chaotic accumulation of data cables inside the rack. This disorder not only affects aesthetics but also obstructs airflow, creating a solid barrier effect and severely impacting the rack's internal heat dissipation efficiency.

[0004] Therefore, a split-type server rack with cable management function is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] Technical problems to be solved

[0006] To address the aforementioned shortcomings of existing technologies, this invention provides a modular server rack with cable management capabilities. This solution addresses the technical problems of low heat dissipation efficiency and difficult maintenance caused by messy cables in traditional server racks. It enables modular rapid assembly of the rack, dynamic zoning management of cables, and intelligent heat dissipation with temperature self-adaptation, significantly improving the rack's space utilization, heat dissipation performance, and ease of maintenance.

[0007] Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This invention provides a detachable server rack with cable management functionality, comprising a frame, ventilation holes, and a cable tying mechanism. The frame is detachable and is assembled from a front frame, a rear frame, and side beams using fixing bolts. The ventilation holes are arranged in an array on the uprights of the front frame. The cable tying mechanism is detachably installed within the ventilation holes and includes a fixing base, an adjustable-depth threaded rod, and a cable tying plate with ventilation grooves. The cable tying mechanism also includes a sealing plate elastically connected to the cable tying plate by a second spring, and a sealing mesh covering the ventilation holes.

[0010] Furthermore, the wire-tying mechanism also includes a temperature-responsive ventilation mechanism, which includes a through hole on the sealing plate and a movable baffle that is driven to open by a phase change material.

[0011] Furthermore, both the front and rear frames adopt a welded structure of columns and beams, and the two ends of the side beams are provided with bolt fixing plates with protruding positioning structures, which form a mortise and tenon fit with the positioning structure on the columns.

[0012] Furthermore, the wire tying mechanism also includes a limiting strip and an adjustable partition for forming a layered cable fixing structure. The limiting strip is disposed on the wire tying plate, and the heat dissipation grooves are arrayed on the surface of the wire tying plate to form a through airflow channel.

[0013] Furthermore, the wire tying plate is provided with a sliding groove, and a card holder is slidably connected to the sliding groove. A first spring is provided between the sliding groove and the card holder.

[0014] Furthermore, a fixing frame for winding the sealing net is fixedly connected to the fixing base, and a sealing plate is connected to the lower end of the sealing net to form a dustproof barrier that expands or contracts as the tying plate moves.

[0015] Furthermore, the temperature-responsive ventilation mechanism includes a sleeve disposed on the tying plate, and the sleeve is provided with a thermistor for sensing the internal temperature of the frame and a phase change material that expands in volume in response to temperature changes.

[0016] Furthermore, the internal chamber of the sleeve is connected to a piston block and a push rod via a third spring, which is used to convert the expansion motion of the phase change material into a thrust on the movable baffle. The movable baffle is installed in the through hole via a torsion spring shaft and normally closes the through hole.

[0017] Furthermore, the phase change material is paraffin.

[0018] Furthermore, when the movable baffle is opened, its outer surface forms a scraping contact with the sealing mesh, thereby achieving a self-cleaning function.

[0019] Beneficial effects

[0020] The technical solution provided by this invention has the following advantages compared with the prior art:

[0021] This invention employs a modular design with a front frame, rear frame, and side crossbeams, connected by fixing bolts. The side crossbeam fixing plates utilize a tensile reinforcement design, effectively enhancing structural strength. Bolt fixing plates are welded to both ends of the side crossbeams, and the columns feature positioning protrusions, forming a mortise and tenon structure. The positioning protrusions and mortise and tenon joints ensure high diagonal accuracy of the frame, eliminating errors and significantly improving seismic performance. Furthermore, each module can be individually packaged and transported, reducing transportation volume and cost. The modular design shortens installation time and improves maintenance efficiency.

[0022] By incorporating ventilation holes in the front frame columns and a built-in detachable cable tying mechanism, the cable tying mechanism can automatically adjust the opening and closing degree of the ventilation holes according to the cable density. The dynamic heat dissipation system can automatically adjust the heat dissipation area according to the cable density, effectively improving heat dissipation efficiency and solving the problem of cable accumulation hindering heat dissipation in traditional cabinets. This achieves orderly layered cable arrangement and automatically balances dust prevention and heat dissipation requirements. When there are few cables, the number of openings for dust prevention is reduced, and when there are many cables, the number of openings for heat dissipation is increased.

[0023] This system achieves temperature-responsive heat dissipation by using a phase change material to drive a movable baffle. The phase change material-driven temperature control mechanism has a fast response speed and adjustable heat dissipation channel opening, ensuring that the temperature response system enhances heat dissipation under high load and reduces dust entry under low load.

[0024] Dynamic dust prevention is achieved by using an adjustable sealing plate in conjunction with an elastic sealing mesh. When the movable baffle moves, it automatically scrapes the dust off the surface of the sealing mesh. The dust removal direction is designed to be outward to avoid dust entering the interior and causing pollution. Thus, dust prevention, heat dissipation and self-cleaning functions are innovatively integrated into a single system. Attached Figure Description

[0040] The present invention will be further described below with reference to embodiments.

[0041] Example:

[0042] Please refer to the appendix. Figure 1-9 This solution proposes a modular server rack with cable management capabilities. Through an innovative cable tying mechanism design, it achieves a dynamic balance between cable density and heat dissipation area. When the number of cables increases, the system automatically expands the open area of ​​the heat dissipation holes; when the number of cables decreases, the openings are reduced, while a sealing mesh maintains dust prevention.

[0043] Specifically, such as Figure 1-3 As shown, frame 1 consists of a front frame 101, a rear frame 102, side crossbeams 103, and fixing bolts 104. Both the front frame 101 and the rear frame 102 are welded together from columns, upper crossbeams, and lower crossbeams. Bolt fixing plates are welded to both ends of the side crossbeams 103, and the columns have protrusions for positioning the bolt fixing plates. The side crossbeams 103 are positioned with the front frame 101 and the rear frame 102 via these protrusions and then locked in place by the fixing bolts 104. By using protrusion positioning and mortise and tenon joints on the bolt fixing plates of the columns and side crossbeams 103 in a single frame, the frame structure is stable after assembly, allowing for rapid positioning, zero diagonal errors, and effectively improving the product's seismic performance. Furthermore, the modules of frame 1 can be quickly disassembled, allowing the product to be shipped in individual accessory packaging, effectively reducing volume and saving transportation costs. The protrusions on the columns have zero-tolerance fit with the crossbeam fixing plates, ensuring high dimensional accuracy. The side crossbeam 103 fixing plates employ a tensile reinforcement design, greatly improving the product's structural strength.

[0044] More specifically, such as Figure 4 As shown, the uprights of the front frame 101 have a concave structure design with evenly distributed heat dissipation holes 2 for heat dissipation inside the chassis. At the same time, each set of heat dissipation holes 2 is equipped with a detachable cable tie mechanism 3 for cable management, which can manage cables horizontally and vertically. This not only facilitates the bundling and arrangement of data cables, but also improves the usable space inside the cabinet.

[0045] The difference is, for example Figure 5-9 As shown, the cable tying mechanism 3 includes a mounting base 301 that is fitted and inserted into the heat dissipation hole 2. The mounting base 301 has threaded holes and is bolted to the upright of the front frame 101, enabling quick installation and disassembly of the cable tying mechanism 3 and allowing for modular assembly and use. The bolt fixing method eliminates the need for welding or complex tools; assembly or removal can be completed with only simple tools. This significantly reduces cabinet installation, upgrade, or maintenance time, especially in high-frequency maintenance environments such as data centers, minimizing downtime.

[0046] A threaded rod 302 is threadedly installed inside the mounting base 301. A retainer 303 is fitted onto the inner surface of the threaded rod 302, which is inserted into the frame 1. A cable tie 304 is slidably mounted on the surface of the retainer 303. By rotating the threaded rod 302 within the mounting base 301, the insertion depth of the retainer 303 into the frame 1 can be adjusted, thereby adjusting the position of the cable tie 304 within the frame 1. Since the cable tying mechanisms 3 are all integrated onto the columns of the front frame 101, this can lead to concentrated cable fixing, causing cable stacking to form a solid barrier that blocks the airflow path of the heat dissipation holes 2, thus preventing the heat generated by the server within the frame 1 from being quickly dissipated. By adjusting the position of the cable tie 304, cables at different locations on the front frame 101 can be distributed in different layers, with gaps between the different layers of cables, thereby achieving effective heat dissipation within the frame 1.

[0047] The surface of the cable tie plate 304 is provided with evenly distributed heat dissipation grooves 309. When the cable is fixed on the cable tie plate 304, the air can flow on both sides of the cable tie plate 304 through the heat dissipation grooves 309, thereby ensuring that the heat inside the frame 1 can flow through the heat dissipation grooves 309 from the surface of the cable and be discharged, thus achieving heat dissipation inside the frame 1.

[0048] It should be noted that the surface of the cable tie plate 304 is connected to a limiting strip plate 307. The surface of the limiting strip plate 307 has gaps, and multiple sets of adjustable and fixed partitions 308 are installed between the gaps. When cables need to be bundled, the cables are placed between the cable tie plate 304 and the limiting strip plate 307. The cables can be bundled between the limiting strip plate 307 and the cable tie plate 304 by the cable clamping strap, thereby achieving the binding and fixing of the cables on the cable tie plate 304. At the same time, two adjacent sets of cables can be separated by the partitions 308, thereby achieving layered fixing and bundling of the cables, which facilitates the subsequent disassembly and maintenance of the cables.

[0049] A sealing plate 311 is installed on the side of the cable tie plate 304 facing the heat dissipation hole 2 via a second spring 310. When the threaded rod 302 adjusts the installation position of the cable tie plate 304 in the frame body 1, the sealing plate 311 will abut against the inner surface of the heat dissipation hole 2 under the action of the second spring 310, thereby sealing the heat dissipation hole 2 and effectively preventing external dust from entering the frame body 1 and causing damage to the server.

[0050] A sliding groove 305 is fixedly connected to the surface of the cable tie plate 304, and the sliding groove 305 is fitted onto the surface of the card holder 303. A first spring 306 connects the card holder 303 and the sliding groove 305, and the cable tie plate 304, under the elastic force of the first spring 306, always has a tendency to be pushed upwards. When the cable tie plate 304 binds and fixes the cables, as the number of cables bound on the cable tie plate 304 increases, the cable density installed on the cable tying mechanism 3 also increases, and the weight of the cable tie plate 304 and the bound cables also increases, indicating that the cable density and cable weight on the cable tying mechanism 3 are directly proportional.

[0051] Therefore, when the tying mechanism 3 has a small number of cables installed, the tying plate 304 is lifted to a higher height under the elastic force of the first spring 306. At this time, the sealing plate 311 will slide upward synchronously with the tying plate 304, blocking the heat dissipation hole 2 to a greater extent. However, at this time, the cable density on the tying mechanism 3 is small, so the heat dissipation hole 2 can be opened in a small space to meet the heat dissipation in the frame 1, and at the same time, it can effectively prevent external dust from entering the frame 1 through the heat dissipation hole 2.

[0052] However, as the number of cables installed on the cable tying mechanism 3 increases, the cable density on the surface of the cable tying plate 304 increases, thus the relatively small open area of ​​the heat dissipation hole 2 cannot meet the heat dissipation requirements within the frame 1. With the increase in the number of cables, the overall weight of the cables and the cable tying plate 304 increases, causing the cable tying plate 304 to overcome the elastic force of the first spring 306 and compress it. Due to the compression of the first spring 306, the slide groove 305 slides downwards along the card holder 303, causing the cable tying plate 304 to slide downwards as well. Since the sealing plate 311 and the cable tying plate 304 move synchronously in the same direction, the sealing plate 311 slides downwards along the inner surface of the heat dissipation hole 2, increasing the exposed area of ​​the heat dissipation hole 2. Therefore, this solution automatically expands the open area of ​​the heat dissipation hole 2 as the cable density increases, improving the heat dissipation effect. Conversely, when the number of cables is small, it automatically reduces the open area of ​​the heat dissipation hole 2 to reduce the possibility of dust entering. Ultimately, a dynamic balance between heat dissipation and dust prevention is achieved within the frame 1.

[0053] It is worth noting that the fixing base 301 is inserted into one side of the frame 1 and connected to a fixing frame 312. A sealing mesh 313 is wound up and installed on the fixing frame 312, and the lower end of the sealing mesh 313 is connected to the side of the sealing plate 311 facing the heat dissipation hole 2. This ensures that when the sealing plate 311 adjusts the opening of the heat dissipation hole 2, the fixing frame 312 can always cover the surface of the heat dissipation hole 2, thus ensuring ventilation while preventing dust from entering the frame 1. Furthermore, as the position of the sealing plate 311 is adjusted, the fixing frame 312 can be pulled to expand or retract synchronously, thereby achieving full-process sealing protection for the heat dissipation hole 2.

[0054] The surface of the sealing plate 311 is provided with vertically distributed through holes 314. Each set of through holes 314 has a movable baffle 315 of matching area mounted inside via a torsion spring shaft. When the movable baffle 315 is not affected by external force, it rotates into the through hole 314 under the elastic force of the torsion spring inside the torsion spring shaft, sealing the inside of the through hole 314. This allows for adjustment of the heat dissipation area of ​​the heat dissipation hole 2.

[0055] The surface of the cable tie plate 304 is equipped with a temperature-responsive ventilation mechanism. When the internal temperature of the frame body 1 rises, the movable baffle 315 is pushed to rotate in the through hole 314 as the internal temperature of the frame body 1 increases, and overcomes the elastic force of the torsion spring shaft to open the through hole 314, thereby increasing the effective heat dissipation area.

[0056] The temperature-responsive ventilation mechanism includes a sleeve 316 connected to a cable tie plate 304. A thermistor 317 is inserted and installed at one end of the sleeve 316 facing the inside of the frame 1. A piston block 319 is slidably mounted inside the sleeve 316 via a third spring 318. A push rod 320 is connected to the surface of the piston block 319. The other end of the push rod 320 extends through to the outside of the sleeve 316 and faces the movable baffle 315. Meanwhile, the interior of the sleeve 316, between the thermistor 317 and the piston block 319, is filled with a phase change material 321. When the heat inside the frame 1 increases, the thermistor 317 transfers heat to the internal phase change material 321. The phase change material 321 expands due to heat, pushing the piston block 319 to slide and overcome the elastic force of the third spring 318. This, in turn, controls the push rod 320 to push the movable baffle 315 to slide within the through hole 314 and rotate towards the heat dissipation hole 2, thus opening the heat dissipation channel and effectively increasing the heat dissipation effect inside the frame 1.

[0057] The phase change material 321 can be paraffin wax. When the temperature rises, solid paraffin wax gradually melts into a liquid state. The phase change temperature range of liquid paraffin wax is 45-65℃, and its volume expansion rate can reach 10%-15%, generating enormous pressure. When the temperature inside the frame 1 decreases, the phase change material 321 re-solidifies, and under the pressure generated by the third spring 318 pushing the piston block 319, it contracts again, completing one working cycle. This achieves the conversion of thermal energy into mechanical energy.

[0058] It is particularly important to note that the mounting bracket 312 covers the outside of the through hole 314. When the movable baffle 315 rotates outward under the thrust of the temperature-responsive ventilation mechanism, the movable baffle 315 will abut against the surface of the mounting bracket 312, wiping and scraping its surface. Consequently, dust will adhere to the surface of the mounting bracket 312 during prolonged use. The movable baffle 315 can scrape off the dust, and the scraping direction is outward from the heat dissipation hole 2, thus achieving the cleaning of the surface of the mounting bracket 312.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
