Description

Technical Field

[0001] This utility model relates to the field of data center computer rooms, and more specifically, to a partitioned column cabinet structure. Background Technology

[0002] As the core of power distribution and management for server rack arrays, data center rack cabinets undertake crucial functions such as overall power control, monitoring and protection, and simplified operation and maintenance, serving as essential infrastructure for ensuring the stable operation of data centers. With the rapid growth in high-density computing demands, especially the widespread application of GPU servers, the power density of a single rack has increased dramatically from less than 10kW in traditional CPU servers to 30kW or even over 50kW. This change has placed entirely new demands on the power handling capacity of rack cabinets.

[0003] Traditional rack-mount power supplies typically have a current rating of no more than 630A and a total power of less than 400kW. While they can support dozens of ordinary servers, their power supply capacity is insufficient when facing high-density GPU racks, supporting only about 10 40kW racks, significantly reducing space utilization efficiency. To adapt to high-power scenarios, modern rack-mount power supplies need to support current ratings exceeding 1000A and total power greater than 650kW. Their integrated electrical systems face severe risks of overheating, insulation issues, and arcing.

[0004] Therefore, it is urgent to solve the heat dissipation and temperature rise control problem under high power operation through one or more innovative structural designs, and to achieve reasonable area division and safety enhancement.

[0005] It should be noted that the information in the background section of the present invention is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art.

That is, these functional entities can be implemented in software, or in one or more software-hardened modules, or in different network and / or processor devices and / or microcontroller devices.

[0051] In this example embodiment, a partitioned column cabinet structure is first provided; Reference Figure 1 and Figure 2 As shown, in this partitioned array cabinet structure, the main circuit breaker incoming line area module 100, the feeder circuit breaker area module 200, and the outgoing line area module 300 are arranged adjacent to each other in sequence, wherein:

[0055] An exemplary embodiment of this utility model provides a partitioned rack-type cabinet structure, comprising a main circuit breaker incoming line area module, a feeder circuit breaker area module, and an outgoing line area module arranged sequentially and adjacently. The main circuit breaker incoming line area module includes a first enclosure with a dense busbar on the top, a first front door, a first removable cover plate at the rear, and a first removable sealing plate on the right side. The feeder circuit breaker area module includes a second enclosure with a fan on the top, a second front door, and a second removable cover plate at the rear. The outgoing line area module includes a third enclosure with a metal door on the front, a third removable cover plate at the rear, and a second removable sealing plate on the left side. This embodiment of the utility model achieves customized allocation of space, avoids unreasonable component layout, improves operational convenience, and reduces safety risks.

[0056] The following will further describe a partitioned column cabinet structure in this example embodiment.

[0057] In the embodiments of this example, as Figures 6 to 12 As shown, the first front door 120 is a door with a glass observation window. A mesh-like first ventilation hole 121 is opened on the bottom surface of the door. A first ventilation opening is provided at the lower inner side of the first front door 120 corresponding to the first ventilation hole 121. External airflow enters the box through the mesh structure at the bottom of the first box after passing through the first ventilation hole 121 and the first ventilation opening.

[0058] The second front door 210 is also a door with a glass observation window. The bottom surface of the door is also provided with a second ventilation hole 211. The lower inner side of the second front door 210 is provided with a second ventilation opening corresponding to the position of the second ventilation hole 211. After the external airflow passes through the second ventilation hole 211 and the second ventilation opening, it enters the box through the mesh structure at the bottom of the second box.

[0059] Apart from their dimensions, the first front door 120 and the second front door 210 are structurally identical.

[0060] Because of the glass observation windows on the first front door 120 and the second front door 210, an external louver structure cannot be used. Also, for aesthetic reasons, the ventilation holes are placed at the bottom of the door panels. However, its advantages are more obvious: each external door can be opened independently, and with the glass observation windows, it is very convenient for maintenance personnel to inspect and observe the real-time status of the cabinets, which is beneficial for daily maintenance.

[0061] The lower end of the metal door 310 is provided with ventilation louvers 311, and its structure is simpler because it needs to be opened and closed frequently.

[0062] In the embodiments of this example, as Figure 13 As shown, the first enclosure is internally equipped with a copper busbar 130 connecting the dense busbar to the main switch circuit breaker, a main switch circuit breaker 140, and a copper busbar 150 at the lower end of the main switch, wherein:

[0063] The incoming end of the copper busbar 130 connecting the busbar to the main switch circuit breaker is connected to the busbar 110, and the outgoing end of the copper busbar 130 connecting the busbar to the main switch circuit breaker is connected to the main switch circuit breaker 140.

[0064] The incoming terminal of the main switch lower copper busbar 150 is connected to the main switch circuit breaker 140, and the outgoing terminal of the main switch lower copper busbar 150 is connected to the feeder circuit breaker area module 200.

[0065] As data center rack power density evolves from 10kW to 40kW+ (especially for AI racks), the rated current of a single rack needs to increase from 800A to 2500A or even higher. This will increase the risk of overheating through cable connections, and making it more inconvenient to connect wires of different specifications. Therefore, the material and structural advantages of dense busbars and integrated copper busbars will become more prominent.

[0066] First, the contact pressure of this connection method is controllable, reducing the risk of overheating. Second, it supports multiple wire specifications and is adaptable to different output capacities. Third, the anti-accidental contact design effectively reduces the risk of electric shock. Fourth, it makes on-site wiring and subsequent maintenance more convenient.

[0067] In the embodiments of this example, as Figure 13 As shown, the interior of the second housing contains several branch switches 230 and branch cables connecting each of the branch switches, wherein:

[0068] The branch switch 230 is provided with a main switch lower copper busbar connection terminal 231 at the inlet end, and the main switch lower copper busbar connection terminal 231 is connected to the outlet end of the main switch lower copper busbar 150.

[0069] One end of the branch cable is connected to each of the branch switches 230, and the other end is connected to the outgoing area module 300.

[0070] The multi-branch switch 230 separates the power supply to different systems, which facilitates the control of a single system.

[0071] In the embodiments of this example, as Figure 13 As shown, the interior of the third enclosure is equipped with a terminal block 320 installed perpendicular to the ground, wherein:

[0072] The power input terminal of the outgoing terminal block 320 is connected to the branch cable;

[0073] The power output terminal of the terminal block 320 is connected to a power output cable extending out of the third housing and connected to equipment of different systems.

[0074] Preferably, the terminal block 320 is disposed in the air inside the third enclosure through insulating components, and does not come into contact with the wall of the third enclosure, thus greatly avoiding the risk of electric shock.

[0075] In the embodiments of this example, as Figures 6 to 12 As shown, high power density leads to high heat dissipation requirements, so the cabinet is equipped with a separate ventilation design. This means that forced convection is the primary method, supplemented by natural ventilation. Forced convection is mainly achieved by a fan 220 with an axial or centrifugal fan at the top of the cabinet, while natural ventilation is supplemented by ventilation holes on the sides and bottom of the cabinet doors, forming a "bottom in, top out" airflow channel.

[0076] Preferably, the partition at the connection between the main circuit breaker incoming line area module 100, the feeder circuit breaker area module 200, and the outgoing line area module 300 can be set as a mesh or the size of the partition can be reduced so that there are gaps at the top and bottom, which makes it easier for airflow to circulate in the cabinet.

[0077] Meanwhile, the fan 220 is electrically connected to the temperature control device, and can automatically start and stop according to the temperature inside the cabinet.

[0078] In the embodiments of this example, as Figure 5As shown, the first removable cover plate 160 is detachably connected to the first housing body via screws and fasteners. The second removable cover plate 240 is detachably connected to the second housing body via screws and fasteners. The third removable cover plate 330 is detachably connected to the third housing body via screws and fasteners.

[0079] The removable individual cover ensures ease of operation and maintenance. When maintenance is required, only the cover of the target partition can be opened (while other partitions remain closed), which improves operational convenience and reduces safety risks.

[0080] It should be noted that although several modules or units of a partitioned column cabinet structure are mentioned in the detailed description above, this division is not mandatory. In fact, according to the embodiments of this utility model, the features and functions of two or more modules or units described above can be embodied in one module or unit. Conversely, the features and functions of one module or unit described above can be further divided and embodied by multiple modules or units.

Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.
