Description

Technical Field

[0001] This invention relates to the field of power cabinet technology, and more specifically to a UPS power supply system for computer rooms. Background Technology

[0002] UPS cabinets provide high-quality power to data centers, server rooms, and other locations requiring centralized management of large amounts of IT equipment during power outages, thus protecting data and equipment. The increasing prevalence of computer applications and the continuous development of information processing technologies are placing increasingly stringent requirements on UPS cabinets in data centers.

[0003] In existing technologies, the replacement of traditional power modules in data center power cabinets requires the removal of bolts, resulting in long maintenance interruptions. Furthermore, the lack of a guide design for cable plugging and unplugging between power modules makes it easy to accidentally touch adjacent modules, leading to power outages. Densely arranged power modules also cause blockages in the heat dissipation airflow, resulting in localized overheating that cannot be quickly resolved, and the fixed installation hinders airflow. Therefore, this application proposes a solution to address the drawbacks of the aforementioned power module installation and layout methods, airflow obstruction, and the risk of accidental contact with adjacent modules during cable plugging and unplugging. Summary of the Invention

[0004] The purpose of this invention is to provide a UPS power supply system for computer rooms, which solves the problems of the power module layout affecting airflow and the easy accidental contact between adjacent modules when plugging and unplugging cables.

[0005] The objective of this invention can be achieved through the following technical solution: a UPS power supply system for a computer room, comprising a cabinet, a base box disposed at the bottom of the cabinet, and a power supply box disposed in the cabinet, wherein a cover is installed on the power supply box, and a cable guide assembly is disposed on the back of the power supply box;

[0006] The cable guiding assembly includes symmetrically arranged hinge plates and locking rods. Both sets of locking rods have wire clamps installed on their adjacent sides for cable positioning. Both sets of locking rods have floating rings fitted onto their adjacent ends. The upper and lower ends of the floating rings are fitted with limiting bolts for longitudinal positioning of the locking rods.

[0007] The floating ring is further configured such that slots are symmetrically provided at both ends, the adjacent ends of the locking rods are inserted into the slots but do not contact each other, and the end of the limiting bolt extending into the floating ring contacts the locking rod.

[0008] The configuration is further defined as follows: there is a wire groove between the locking rod and the power supply box, and the adjacent sides of the wire clamps are provided with circular pressure holes. The cable passes through the wire groove and through the pressure holes between the two sets of wire clamps to form a fixed cable.

[0009] The cabinet is further configured such that: an inner frame is installed in the cabinet, side panels are arranged in an array on the sides of the inner frame, symmetrically distributed slide rail base rods are installed on the side panels, and slide rods connected to the power supply box are slidably installed on the slide rail base rods.

[0010] A further configuration is provided: a locking plate is symmetrically installed on the back of the power supply box, and the hinge plate is fixed to the middle of the locking plate and does not contact the back of the power supply box.

[0011] The system is further configured such that: a fan is installed in the bottom box, and a through air inlet and an air outlet are respectively opened between the bottom of the cabinet and the bottom box, which together with the gap of the power supply box in the cabinet form an air duct.

[0012] The cabinet is further configured such that a cabinet door is hinged to the front side of the cabinet, and a back panel is installed on the rear side of the cabinet. The back panel is a mesh structure, and the gap between the back panel, the power supply box, the cabinet door, the air inlet, and the air outlet together form a three-dimensional circulating convection channel.

[0013] The cabinet is further configured to include a high-voltage box module, and the cabinet door is equipped with a lock for protecting the power supply box and the high-voltage box module inside the cabinet.

[0014] The present invention has the following beneficial effects:

[0015] 1. This invention addresses the problems of power module arrangement affecting airflow and accidental contact with adjacent modules during cable plugging and unplugging. By combining floating rings with cable trays to guide and restrict cables, the cable guiding components limit the wires of each power module. It also organizes and arranges cables in the power cabinet of the computer room to form a three-dimensional circulating air duct. The combination of these two methods not only avoids the problem of accidental contact with adjacent modules during cable plugging and unplugging but also solves the problem of poor airflow caused by the overall dense arrangement of power modules, further enabling the computer room to supply high-quality power without restriction.

[0016] 2. During the cable guiding process of the power module, a floating ring forms a floating connection, which, together with the locking rods and wire clamps symmetrically set on both sides, effectively mounts the cable. The cable is then locked after mounting by the limit bolts, thus preventing the cable from falling off after positioning. In addition, the cable connection in each power module is set up independently in a partitioned manner to prevent accidental contact with adjacent modules during cable plugging and unplugging, which could cause power interruption.

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] To address the issues of power module layout affecting airflow and accidental contact with adjacent modules during cable plugging / unplugging, the following technical solution is proposed:

[0030] Reference Figure 1 - Figure 8 As shown, in this embodiment, a UPS power supply system for a computer room includes a cabinet 1, a bottom box 4 located at the bottom of the cabinet 1, and a power supply box 6 located in the cabinet 1. The power supply box 6 is equipped with a cover 7, and a cable guide assembly is provided on the back of the power supply box 6.

[0031] Reference Figure 5 As shown, the cable guiding assembly includes symmetrically arranged hinge plates 16 and locking rods 17. The adjacent sides of the two sets of locking rods 17 are equipped with cable clamps 18 for cable limiting. The adjacent ends of the two sets of locking rods 17 are jointly fitted with floating rings 19. The upper and lower ends of the floating rings 19 are equipped with limiting bolts 21 for longitudinal limiting of the locking rods 17.

[0032] The floating ring 19 has symmetrical slots 20 at both ends. The near ends of the locking rods 17 are inserted into the slots 20 without contacting each other. The end of the limiting bolt 21 extends into the floating ring 19 and contacts the locking rod 17. When the locking rod 17 is inserted through the slots 20 on both sides of the floating ring 19, the wire groove on the wire clamp 18 forms a preliminary positioning for the inserted cable. The cable finally passes through the hollow part of the floating ring 19 for wiring. The limiting bolt 21 then completes the limiting and pressing on the upper and lower sides, thereby completing the binding of the individual power module cable and avoiding the problem of power interruption caused by mutual constraints and inability to perform independent maintenance.

[0033] This embodiment provides a cable arrangement method for a UPS power module in a server rack. Specifically, a floating ring 19 forms a floating connection, which, together with locking rods 17 and wire clamps 18 symmetrically arranged on both sides, effectively mounts the cables. The cables are then locked after mounting by limit bolts 21, thereby preventing the cables from falling off after positioning. Furthermore, the cable connections in each power module are set up independently in separate zones to prevent accidental contact with adjacent modules during cable plugging and unplugging, which could cause power outages.

[0034] Reference Figure 5 and Figure 7 As shown, there is a cable groove 22 between the locking rod 17 and the power box 6. The adjacent sides of the cable clamps 18 are provided with circular pressure holes. The cable passes through the cable groove 22 and through the pressure holes between the two sets of cable clamps 18 to form a fixed cable. The cable of the power box 6 is led out from the rear end, and the end is clamped and fixed by the cable clamps 18 and the floating ring 19. That is, the long part of the cable is located in the cable groove 22 for effective storage, which is convenient for maintenance or repair.

[0035] Reference Figure 1 and Figure 2As shown, a fan is installed in the bottom box 4, and an air inlet 9 and an air outlet 10 are respectively opened between the bottom of the cabinet 1 and the bottom box 4. Together with the gap of the power supply box 6 in the cabinet 1, they form an air duct 23. A cabinet door 2 is hinged to the front side of the cabinet 1, and a back panel 12 is installed on the rear side of the cabinet 1. The back panel 12 is a mesh structure, and the gap between the back panel 12, the power supply box 6, the cabinet door 2 and the air inlet 9 and the air outlet 10 together form a three-dimensional circulating convection channel.

[0036] It should be noted that the three-dimensional circulating convection channel is set relative to the cabinet. During the convection process, the air is guided by the fan set in the bottom box 4, enters through the mesh on the back panel 12, passes through the gaps between each power module and enters the air duct 23, and finally gathers at the air inlet 9 and is discharged from the air outlet 10. That is, the airflow direction of the three-dimensional circulating air duct can ventilate and dissipate heat for each power module, and there is no problem of airflow obstruction.

[0037] Basic principle: Applied to power cabinets in computer rooms, it essentially uses floating rings 19 combined with cable trays 22 to guide and restrict cables, allowing the cable guiding components to limit the wires of each power module. This enables the cables in the power cabinet to be organized and arranged to form a three-dimensional circulating air duct, thereby not only avoiding the problem of accidental contact with adjacent modules during cable plugging and unplugging, but also solving the problem of poor airflow caused by the overall dense arrangement of power modules, further realizing the problem of unrestricted supply of high-quality power to the computer room.

[0038] Example 2

[0039] Reference Figures 1-8 As shown, the cabinet includes: an inner frame 3 installed in the cabinet 1; side panels 11 are arranged in an array on the sides of the inner frame 3; symmetrically distributed slide rail bottom rods 13 are installed on the side panels 11; slide rods 14 connected to the power supply box 6 are slidably installed on the slide rail bottom rods 13; locking plates 15 are symmetrically installed on the back of the power supply box 6; and hinge plates 16 are fixed to the middle of the locking plates 15 and do not contact the back of the power supply box 6.

[0040] In conjunction with Embodiment 1, the slide rail base rod 13 and slide rod 14 provided in this embodiment can provide the power module with independent operation. When it is necessary to perform inspection or maintenance work on a certain power module, it is only necessary to pull out the corresponding power box 6. During the pulling process, the power module's cable is not restricted by the adjacent power module and can be operated independently.

[0041] The cabinet 1 is also equipped with a high-voltage box module 5, and the cabinet door 2 is equipped with a lock body 8 for protecting the power supply box 6 and the high-voltage box module 5 inside the cabinet 1.

[0042] In summary, this invention provides a power supply cabinet for a data center. The floating ring 19 combined with the cable tray 22 forms a guiding and restrictive structure for the cables, allowing the cable guiding components to limit the movement of wires in each power module. Furthermore, it organizes and arranges the cables within the power supply cabinet to form a three-dimensional circulating air duct. This combination not only avoids the problem of accidental contact with adjacent modules during cable insertion and removal but also solves the problem of poor airflow caused by the dense arrangement of power modules, further ensuring unrestricted high-quality power supply to the data center.
