[0027] Unless otherwise indicated, corresponding numbers and symbols in different drawings generally refer to corresponding parts. These drawings are drawn to clearly illustrate the relevant aspects of various embodiments and are not necessarily drawn to scale. Detailed Implementation
[0028] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] See Figure 1 The exploded three-dimensional structure diagram of the power cabinet of the first embodiment provided in this application is shown. The power cabinet provided in this application is divided into at least a first installation area 21 and a second installation area 31 from top to bottom in the vertical direction (Z-axis), and includes a front end 11 and a rear end 12 opposite to the front end 11 in the horizontal direction (Y-axis).
[0030] Please refer to the following: Figure 1 At least one first AC voltage distribution unit 22 and at least one first DC voltage distribution unit 23 are installed in the first installation area 21. Please refer to... Figure 2 The diagram shown is a side view of the power cabinet in the X-axis direction of the first embodiment provided in this application, illustrating the structural arrangement. The AC input line 41 is connected at the front end 11 of the power cabinet to the first terminal 221 of the at least one first AC voltage distribution unit 22. Please refer to [further details omitted]. Figure 1 The first AC voltage distribution unit 22 is installed in the first installation area 21 by inserting or withdrawing it from the power cabinet from the rear end 12 of the power cabinet, and the first DC voltage distribution unit 23 is installed in the first installation area 21 by inserting or withdrawing it from the front end 11 of the power cabinet.
[0031] Please refer to the following: Figure 1 At least one second AC voltage distribution unit 32 and at least one second DC voltage distribution unit 33 are installed in the second installation area 31. Please refer to the following: Figure 2 The AC input line 41 is connected at the front end of the power cabinet to the first terminal 321 of the at least one second AC voltage distribution unit 32. Please refer to [further details]. Figure 1 The second AC voltage distribution unit 32 and the second DC voltage distribution unit 33 are installed in the second installation area 31 by inserting or removing them from the front end 11 of the power cabinet.
[0032] Accordingly, by setting up at least two sets of AC voltage distribution units and DC voltage distribution units, if any of the AC voltage distribution units and / or DC voltage distribution units are damaged or need to be replaced, the connection lines of the faulty AC voltage distribution unit and / or DC voltage distribution unit can be disconnected and pulled out, and then a new AC voltage distribution unit or DC voltage distribution unit can be inserted and connected without affecting the operation of the overall power cabinet. In other words, hot-swapping is supported, and replacement can be done without stopping the machine, thus reducing maintenance costs.
[0033] For further details, please refer to Figure 3 The diagram shown illustrates the structural layout of the front end of the power cabinet according to the first embodiment of this application. Please refer to the diagram for further details. Figure 1 and Figure 2 The at least one first DC voltage distribution unit 23 (located in the upper first mounting area 21) and the at least one second DC voltage distribution unit 33 (located in the lower second mounting area 31) are stacked vertically and located at the first coordinate position on the X-axis. The at least one first AC voltage distribution unit 22 (located in the upper first mounting area 21) is stacked on top of the at least one second AC voltage distribution unit 32 (located in the lower second mounting area 31) and located at the second and third coordinate positions on the X-axis. The AC input lines 41 are all introduced from the front end 11 of the power cabinet, and the at least one first AC voltage distribution unit 22 is inserted or withdrawn from the rear end 12 of the power cabinet. The at least one first DC voltage distribution unit 23, the at least one second AC voltage distribution unit 32, and the at least one second DC voltage distribution unit 33 are inserted or withdrawn from the front end 11 of the power cabinet. Please refer to [link / reference]. Figure 1 And please combine Figure 8 The exploded three-dimensional structural diagram provided in this application, including an upper frame, a lower frame, a first AC voltage distribution unit, a first DC voltage distribution unit, a second AC voltage distribution unit, and a second DC voltage distribution unit, illustrates the positional relationship and insertion or extraction direction of each functional module (mainly including the first AC voltage distribution unit 22, the first DC voltage distribution unit 23, the second AC voltage distribution unit 32, and the second DC voltage distribution unit 33). It is evident that the power cabinet provided in this application achieves clear functional zoning of each module, distinct spatial hierarchy, and staggered structural arrangement in the vertical and horizontal directions. Each functional module operates independently during assembly, operation, maintenance, and expansion, allowing for both single-module operation and simultaneous multi-module operation. For example, when the first AC voltage distribution unit 22 located in the first installation area 21 on the upper layer needs to be inserted into or removed from the power cabinet, it can be inserted into or removed from the power cabinet from the rear end 12 of the power cabinet, which can avoid interference with the AC input line 41, and can also avoid interference with the first DC voltage distribution unit 23, the second AC voltage distribution unit 32 and the second DC voltage distribution unit 33, thus ensuring the normal operation of other functional modules.
[0034] Please refer to the following: Figure 1 and Figure 3 Please see Figure 4 The diagram shows a partial view of the structural layout of the rear end of the power cabinet according to the first embodiment of this application. Please refer to [link / reference]. Figure 5 The diagram shows a partial side view of the structural arrangement provided in this application, including an upper frame, a lower frame, a first AC voltage distribution unit, a first DC voltage distribution unit, a second AC voltage distribution unit, a second DC voltage distribution unit, an AC / DC conversion module, and a busbar, along the X-axis. The power cabinet provided in this application also includes a busbar 13. The busbar 13 is located at the rear end 12 of the power cabinet, and its length direction is aligned with the vertical direction (Z-axis) of the power cabinet. The at least one first DC voltage distribution unit 23 has a DC input terminal 231 on one side of the rear end 12 of the power cabinet, and the at least one second DC voltage distribution unit 33 has a DC input terminal 331 on one side of the rear end 12 of the power cabinet. The DC input terminals 231 and 331 are pluggable onto the busbar 13. That is, the at least one first DC voltage distribution unit 23 and the at least one second DC voltage distribution unit 33 are rigidly connected to the busbar 13.
[0035] See Figure 4 The image shown is a partial view of the structural layout of the rear end of the power cabinet according to the first embodiment of this application. Please refer to the accompanying image. Figure 1 and Figure 3 Busbar 13 is located at the rear of the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 in the horizontal X-axis direction, and is formed by... Figure 4 In the illustrated embodiment, the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 are located in the middle of the power cabinet in the horizontal X-axis direction. Therefore, the busbar 13 is located in the middle of the rear end 12 of the power cabinet in the horizontal X-axis direction. The busbar 13 passes through the first mounting area 21 and the second mounting area 31 and extends to the bottom of the second mounting area 31 to facilitate the connection of the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 with the busbar 13. Other functional modules that need to be connected to the busbar 13 in the bottom of the second mounting area 31 are connected to the busbar 13 at the rear end 12 of the power cabinet.
[0036] See Figure 1 to Figure 5The power cabinet provided in this application also includes an AC / DC conversion module 50. In the vertical direction (Z-axis) of the power cabinet, the AC / DC conversion module 50 is located below the second mounting area 31. The AC / DC conversion module 50 includes an AC input terminal 51 on one side of the rear end 12 of the power cabinet. The first AC voltage distribution unit 22 includes an AC output terminal 222 on one side of the rear end 12 of the power cabinet, and the second AC voltage distribution unit 32 includes an AC output terminal 322 on one side of the rear end 12 of the power cabinet. The AC output terminals 222 and 322 are connected to the AC input terminal 51 of the AC / DC conversion module 50 via connecting lines (not shown in the figure), allowing the AC / DC conversion module to receive AC input voltage. It can be seen that the at least one first AC voltage distribution unit 22 and the at least one second AC voltage distribution unit 32 are softly connected to the AC / DC conversion module 50, and the connecting wires are distributed vertically downward from the first AC voltage distribution unit 22 and the second AC voltage distribution unit 32 or bent downward to the AC input terminal 51 of the AC / DC conversion module. The wiring is clear and easy to see, realizing a seamless connection between points.
[0037] See Figure 4 to Figure 5 Similar to the at least one first DC voltage distribution unit 23 and the at least one second DC voltage distribution unit 33, the AC / DC conversion module 50, located on one side of the rear end 12 of the power cabinet, also includes a DC output connection terminal 52. The DC output connection terminal 52 is pluggably connected to the busbar 13 to output DC power to the busbar 13. This enables AC-DC conversion, meaning the AC / DC conversion module is rigidly connected to the busbar 13.
[0038] Furthermore, busbar 13 conducts the DC power received from the DC output connection terminal 52 of AC / DC converter module 50 to the DC input terminal 231 of the first DC voltage distribution unit 23 and the DC input terminal 331 of the second DC voltage distribution unit 33. Accordingly, DC voltage can be provided to the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33.
[0039] Please see Figure 1 and Figure 2 The power cabinet has a second cable channel 142 on its top plate 14 in the vertical direction (Z-axis). Please refer to the relevant documentation. Figure 4 The first DC voltage distribution unit 23, located on one side of the rear end 12 of the power cabinet, also includes a DC output terminal 232, and the second DC voltage distribution unit 33, located on one side of the rear end 12 of the power cabinet, also includes a DC output terminal 332. Please refer to... Figure 2 The power cabinet also includes a DC output line 42, one end of which is connected to DC output terminals 232 and 332, and extends upward through the second cable channel 142 to the outside of the power cabinet.
[0040] Please see Figure 1 and Figure 2 The power cabinet has a first cable channel 141 on its upper top plate 14 along the vertical Z-axis. An AC input line 41 passes through the first cable channel 141 and extends to and connects to the first end 221 of the first AC voltage distribution unit 22. In one embodiment, please refer to [further details omitted]. Figure 2 A cable channel is also provided at the first end 321 of the second AC voltage distribution unit 32 on the upper tray 15. The AC input line 41 passes through the first cable channel 141 and the cable channel on the upper tray 15 in sequence, and extends to the first end 321 of the second AC voltage distribution unit 32 and connects to it at the first end 321. In another embodiment, please refer to... Figure 5 ,and Figure 2 The difference is that, in Figure 5 In the illustrated embodiment, the upper tray 15 retracts inward toward the power cabinet until it avoids the first end 321 of the second AC voltage distribution unit 32, so that the AC input line 41, after passing through the first cable channel 141, can directly extend to and connect with the first end 321 of the second AC voltage distribution unit 32. That is, as shown... Figure 5 As shown, in the Y-axis direction, the upper tray 15 is shorter than the lower tray 16. Specifically, the upper tray 15 is located on one side of the front end 11 of the power cabinet and is recessed into the power cabinet to avoid the AC input line 41 extending to the first end 321 of the second AC voltage distribution unit 32.
[0041] As described above, the AC input line 41 at the front end 11 of the power cabinet extends from top to bottom to the front end of the first AC voltage distribution unit 22 and the second AC voltage distribution unit 32, providing AC input to the power cabinet. The flexible and rigid connections at the rear end 12 of the power cabinet are staggered on the horizontal X-axis. The connection lines at the rear end 12 of the power cabinet are distributed downwards from the first AC voltage distribution unit 22 and the second AC voltage distribution unit 32 in a waterfall-like manner, connecting to the AC input terminal 51 of the AC / DC conversion module 50. Then, the DC output line 42 extends upwards from the DC output terminals 232 and 332 of the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33, passing through the second cable channel 142 and extending to the outside of the power cabinet, enabling the power cabinet to provide DC output. It can be seen that all the connection lines are distributed upwards or downwards in a waterfall-like manner, with clear and easy-to-see wiring. This ensures that the front and rear maintenance passages are always clean and open, and the front and rear of the integrated cabinet are "clean corridors with an unobstructed view". Avoid the tangled mess of power and signal cables between modules, which is time-consuming and laborious to manage, and makes troubleshooting akin to "finding a needle in a haystack." Transform cable management from a "webbed hole" and "cable jungle" into an "artwork."
[0042] As described above, the AC input of the power cabinet is input downwards through AC input line 41 at the front end of the power cabinet to the first AC voltage distribution unit 22 and the second AC voltage distribution unit 32. After being processed by the first AC voltage distribution unit 22 and the second AC voltage distribution unit 32, the AC input is connected to the AC input terminal 51 of the AC / DC conversion module 50 at the rear end of the power cabinet via a flexible cable. The DC output of the AC / DC conversion module 50 is plugged into the busbar, which conducts DC power to the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33. After processing, the DC output of the power cabinet is output upwards through DC output line 42 at the rear end of the power cabinet. Accordingly, an AC-DC power cabinet can be realized. It can be seen that the power distribution path of the power cabinet provided in this application is extremely simplified, and the physical distance between AC / DC conversion and power distribution link is minimized, which greatly reduces transmission loss and improves overall energy efficiency.
[0043] Please refer to the following: Figure 1 , Figure 3 and Figure 4 The first AC voltage distribution unit 22 includes at least two units, and on the horizontal X-axis, the first AC voltage distribution unit 22 is provided on both sides of the first DC voltage distribution unit 23. Figure 1 , Figure 3 and Figure 4 The embodiment shown is a symmetrical arrangement, with two first AC voltage distribution units 22 arranged on each side of the two stacked first DC voltage distribution units 23 located in the middle.
[0044] Please refer to the following: Figure 1 , Figure 3 and Figure 4 The second AC voltage distribution unit 32 includes at least two units, and on the horizontal X-axis, the second AC voltage distribution unit 32 is provided on both sides of the second DC voltage distribution unit 33. Figure 1 , Figure 3 and Figure 4 The embodiment shown is a symmetrical arrangement, with two second AC voltage distribution units 32 arranged on each side of the two stacked second DC voltage distribution units 33 located in the middle.
[0045] Please see Figure 6 The diagram shown is a structural layout diagram of the front end of the power cabinet according to the second embodiment provided in this application. Figure 7 The partial view of the rear structure of the power cabinet according to the second embodiment of this application shows that, on the horizontal X-axis, the first AC voltage distribution unit 22 is disposed on one side of the first DC voltage distribution unit 23. As shown in the embodiment, two first DC voltage distribution units 23 are stacked on one side, and four first AC voltage distribution units 22 are arranged sequentially along the X-axis on the other side.
[0046] See Figure 6 and Figure 7 As shown, on the horizontal X-axis, the second AC voltage distribution unit 32 is disposed on one side of the second DC voltage distribution unit 33. The embodiment shown in the figure: two second DC voltage distribution units 33 are stacked vertically on one side, and four second AC voltage distribution units 32 are arranged sequentially along the X-axis on the other side.
[0047] As in the power cabinets of the first and second embodiments, the busbar 13 is located in the middle of the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 in the horizontal X-axis direction. In fact, the position of the busbar 13 in the horizontal X-axis direction can move along with the positions of the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 in the horizontal X-axis direction to facilitate the connection between the busbar 13 and the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33.
[0048] For the power cabinet in the second embodiment, the second cable channel 142 can be adjusted according to the positions of the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 to ensure that the DC output line 42 passes upward through the second cable channel 142 via the shortest path and extends to the outside of the power cabinet. Similarly, the first cable channel 141 can be adjusted according to the positions of the first end 221 of the first AC voltage distribution unit 22 and the first end 321 of the second AC voltage distribution unit 32 to ensure that the AC input line 41 passes downward through the first cable channel 141 via the shortest path and connects to the first end 221 of the first AC voltage distribution unit 22 and the first end 321 of the second AC voltage distribution unit 32.
[0049] See Figure 1 , Figure 2 and Figure 5 The first end 221 of the first AC voltage distribution unit 22 and the first end 321 of the second AC voltage distribution unit 32 are arranged in a stepped manner, receding inward from bottom to top into the power cabinet. This allows operators to easily connect the AC input line 41 to the first end 221 of the first AC voltage distribution unit and the first end 321 of the second AC voltage distribution unit.
[0050] In one embodiment, the first terminal 221 of the first AC voltage distribution unit 22 and the first terminal 321 of the second AC voltage distribution unit 32 are arranged in a plane. This embodiment can also connect the AC input line 41 to the first AC voltage distribution unit 22 and the second AC voltage distribution unit 32. That is, this application does not limit the arrangement of the first terminal 221 of the first AC voltage distribution unit 22 and the first terminal 321 of the second AC voltage distribution unit 32.
[0051] See Figure 2 The first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 are installed inside the power cabinet on one side of the front end 11 of the power cabinet in a recessed manner. That is, at the front end 11 of the power cabinet, there is space between the first DC voltage distribution unit 23 and the second DC voltage distribution unit 33 and the front end 11 of the power cabinet, so that the operator can easily connect the AC incoming line 41 to the first end 221 of the first AC voltage distribution unit and the first end 321 of the second AC voltage distribution unit.
[0052] Please refer to the following: Figure 1 to Figure 7 The power cabinet also includes an upper tray 15 and a lower tray 16.
[0053] A first mounting area 21 is created between the upper tray 15 and the upper top plate 14 of the power cabinet in the vertical direction. A second mounting area 31 is created between the lower tray 16 and the upper tray 15. More specifically, the AC / DC conversion module 50 is located on the lower tray 16 below the power cabinet in the vertical direction.
[0054] In practical applications, the lower tray 16 and the upper tray 15 are fixed and installed on the power cabinet.
[0055] See Figure 1 , Figure 2 and Figure 5 The power cabinet also includes: an upper socket frame 17 and a lower socket frame 18. Please refer to [link / reference needed]. Figure 8The exploded perspective view of the structure provided in this application includes an upper frame, a lower frame, a first AC voltage distribution unit, a first DC voltage distribution unit, a second AC voltage distribution unit, and a second DC voltage distribution unit. The upper frame 17 is located in the first mounting area 21 and is mounted on the power cabinet. The upper frame 17 is divided by a partition plate 171 into an AC voltage distribution unit accommodating space 172 and a DC voltage distribution unit accommodating space 173. The first AC voltage distribution unit 22 is installed in the AC voltage distribution unit accommodating space 172 in a pluggable or removable manner, and the first DC voltage distribution unit 23 is installed in the DC voltage distribution unit accommodating space 173 in a pluggable or removable manner. Accordingly, each first AC voltage distribution unit 22 and each first DC voltage distribution unit 23 can be independently and stably installed in a predetermined position. The lower insertion frame 18 is located in the second installation area 31 and is mounted on the power cabinet. The lower insertion frame 18 is divided by a partition plate 181 into an AC voltage distribution unit accommodating space 182 and a DC voltage distribution unit accommodating space 183. The second AC voltage distribution unit 32 is installed in the AC voltage distribution unit accommodating space 182 in a pluggable or removable manner, and the second DC voltage distribution unit 33 is installed in the DC voltage distribution unit accommodating space 183 in a pluggable or removable manner. Accordingly, each second AC voltage distribution unit 32 and the second DC voltage distribution unit 33 can be independently and stably installed in a predetermined position.
[0056] In one embodiment, the first DC voltage distribution unit 23 is assembled as a whole to form a first DC voltage distribution module; the second DC voltage distribution unit 33 is assembled as a whole to form a second DC voltage distribution module. For Figure 1 to Figure 8 The two first DC voltage distribution units 23 are independent of each other, simply stacked one on top of the other, separated by a partition plate 174 in the upper frame 17; the two second DC voltage distribution units 33 are also independent of each other, simply stacked one on top of the other, separated by a partition plate 184 in the lower frame 18. In practice, for ease of installation, multiple first DC voltage distribution units 23 and multiple second DC voltage distribution units 33 can be assembled into a single unit, and then assembled as a whole into the upper and lower frames. In this case, no partition plate 174 is needed in the upper frame 17, and no partition plate 184 is needed in the lower frame 18. Alternatively, the assembled DC voltage distribution units can be assembled into a single independent frame, and then the frame can be inserted into the upper and lower frames or directly assembled into the corresponding positions in the first installation area 21 and the second installation area 31. This method is more convenient for installation.
[0057] In fact, limit structures can also be set in the upper frame 17 and the lower frame 18 to limit the position of each functional module and the direction of insertion and / or extraction.
[0058] In practical applications, there is no limitation on how many regions the lower frame is divided into, or the shape and size of the regions. This can be designed according to the number and shape of the first AC voltage distribution unit 22, the first DC voltage distribution unit 23, the second AC voltage distribution unit 32, and the second DC voltage distribution unit 33.
[0059] Similarly, this application does not limit the number of the first AC voltage distribution unit 22, the first DC voltage distribution unit 23, the second AC voltage distribution unit 32, and the second DC voltage distribution unit 33, as long as it includes two sets of AC voltage distribution units and DC voltage distribution units that can serve as backups for each other and support hot-swapping. In practice, it can be determined according to the power level of the overall power cabinet.
[0060] In practice, the DC output voltage provided by the power supply cabinet can be 800V or -400V to 400V; this application does not limit its output voltage level. However, the technical solution provided in this application is more advantageous when the power supply cabinet is a high-voltage DC power supply cabinet.
[0061] The above example illustrates this application using two layers of AC voltage distribution units and DC voltage distribution units. However, in practical applications, the number of layers of AC voltage distribution units and DC voltage distribution units is not limited, nor is the number of AC voltage distribution units and DC voltage distribution units in each layer limited. The number of layers and the number of AC voltage distribution units and DC voltage distribution units in each layer can be adjusted to suit the power level and output voltage level of the power cabinet.
[0062] In practical applications, other functional units such as battery backup units and capacitor-buffer units can also be installed in the area below the second installation area 31 to realize functions such as computing, communication, and control. Accordingly, the whole structure forms a scalable power supply rack, becoming a core power supply component in data centers and AI servers.
[0063] The above are specific embodiments of the power cabinet provided in this application. The technical effects achieved by this application are: convenient hot-swappable replacement of functional modules, open modularity for expansion to facilitate power supply voltage upgrades, simple assembly, clear wiring, and easy subsequent maintenance.
