Description

Technical Field

[0001] This application relates to the field of computing device technology, and more particularly to a cabinet and computing device. Background Technology

[0002] To improve the power conversion efficiency of computing devices, centralized power supply has become the main power supply method for server racks.

[0003] As server rack power continues to increase, the current carrying capacity required for the power bus also increases, leading to a continuous increase in the size and heat generation of the power bus. In related technologies, the power bus mainly relies on natural heat dissipation. However, when the power of the server rack increases to hundreds of kilowatts or more, the above-mentioned heat dissipation methods become insufficient to effectively reduce the temperature, resulting in increasingly higher design complexity and cost for the power bus. Utility Model Content

[0004] This application provides a cabinet and computing device that can reduce the heat generated by the power bus, thereby reducing the size of the power bus and lowering the design complexity and cost of the power bus.

[0005] In a first aspect, this application provides a cabinet, including a power supply frame and a power bus;

[0006] The aforementioned power supply frame is disposed on the side of the cabinet along a first direction, which is the height direction of the cabinet;

[0007] The aforementioned power bus is close to the power frame, and the horizontal distance between the aforementioned power bus and the power frame is less than the first threshold.

[0008] The power supply frame includes multiple interfaces, each of which is connected to a power bus.

[0009] The cabinet provided in this application embodiment, by setting the power supply frame on the side of the cabinet and the power bus close to the power supply frame, can effectively shorten the average distance between the power supply frame and the computing node, reduce the length of the actual current path of the power bus, thereby reducing the heat generation of the power bus, and further reducing the size of the power bus, as well as the design complexity and cost of the power bus.

[0010] In one possible implementation, the length L of the power supply frame in the first direction satisfies the following condition:

[0011] k×H<L<H;

[0012] Where H is the height of the cabinet, 0.5 < k < 1.

[0013] In the above embodiments, by limiting the length of the power supply frame, the average distance between the power supply frame and each computing node can be kept within a small range, thereby reducing the length of the actual current path of the power bus.

[0014] In one possible implementation, the first threshold d satisfies the following condition:

[0015] 0 < d < 0.5 × W;

[0016] Where W is the width of the server rack.

[0017] In the above embodiments, by reasonably controlling the horizontal distance between the power bus and the power frame, the length of the power transmission path can be ensured to be within a reasonable range. This avoids both overheating issues and operational inconvenience caused by excessively close distances, and increased power transmission losses due to excessively long distances.

[0018] In one possible implementation, the center position of the power supply frame in the first direction is the same as the center position of the cabinet in the first direction.

[0019] In the above embodiments, placing the power supply frame at the center of the side of the cabinet can help shorten the average distance from the power supply frame to each computing node.

[0020] In one possible implementation, the power supply frame is disposed on any one side of the cabinet along the first direction.

[0021] In the above embodiments, the power supply frame is arranged along the height of the rack, which helps to save vertical space in the rack and allows more computing nodes to be installed without increasing the rack height.

[0022] In one possible implementation, the aforementioned plurality of interfaces are evenly distributed on the power supply frame along a first direction.

[0023] In the above embodiments, when multiple computing nodes are connected to the power supply at the same time, the evenly distributed interfaces can ensure that the current load borne by each interface is relatively balanced, avoiding problems such as interface overheating and damage caused by excessive local load, and improving the stability of power supply.

[0024] In one possible implementation, the power supply frame includes multiple power modules, with different power modules connected to different interfaces.

[0025] In one possible implementation, the cabinet is provided with at least one computing node, which is connected to the power bus.

[0026] In one possible implementation, the number m of the above interfaces satisfies the following condition:

[0027] 1 < m < n;

[0028] Where n is the number of computing nodes.

[0029] In the above implementation, by rationally planning the number of interfaces, unnecessary interface redundancy is avoided, thereby reducing the manufacturing and maintenance costs of the power supply frame.

[0030] Secondly, this application provides a computing device that includes a cabinet as described in the first aspect above.

[0031] The computing device provided in this application embodiment can help reduce the design complexity and cost of computing devices. Attached Figure Description

[0053] Exemplary embodiments of this application will be described in detail below. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0054] To facilitate a clear description of the technical solutions in the embodiments of this application, terms such as "exemplary" and "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0055] In this application embodiment, "at least one" refers to one or more, and "more than one" refers to two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0056] Data centers are typically global collaborative networks of specific devices used to transmit, accelerate, display, compute, and store data information on network infrastructure.

[0057] See Figure 1 As shown, Figure 1 This application provides a schematic diagram of a data center architecture. The data center 10 may include a server room 100, which contains at least one server rack 200. The number of server racks 200 may include, but is not limited to, [other details needed]. Figure 1The three shown may include, for example, 10-50 server racks 200. The server room 100 is equipped with a cooling system 110. In this embodiment, the specific structure and working principle of the cooling system 110 within the server room 100 are not described in detail.

[0058] The cabinet 200 can be a communication cabinet, a power supply cabinet, or a rack server, such as a full-rack server or a rack server. Alternatively, the cabinet 200 can also be a cooling cabinet for cooling the servers. In addition, each server can correspond to one cooling cabinet, or multiple servers can correspond to one cooling cabinet.

[0059] Among them, rack servers, due to their high space utilization and high power efficiency, can be widely used in fields such as cloud computing, high performance computing (HPC), big data, and artificial intelligence.

[0060] See Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a cabinet provided in an embodiment of this application.

[0061] In this embodiment, the shape and structure of the cabinet 210 of the cabinet 200 are not specifically limited. The shape of the cabinet 210 can be determined according to the shape of the computing node 220. For example, when the computing node 220 is a rectangular plate structure, the shape of the cabinet 210 can be a cuboid. In addition, the cabinet 210 is provided with a support structure to support the computing node 220. For example, along the height direction (z-axis direction) of the cabinet 210, multiple support plates are spaced apart on the side walls of the cabinet 210, or multiple support rings are spaced apart on the side walls of the cabinet 210.

[0062] Optionally, at least one computing node 220 is provided within the cabinet 210. For example, Figure 2 The cabinet 210 contains multiple computing nodes 220, which are placed horizontally at intervals within the cabinet 210. The thickness of each computing node 220 is "H1".

[0063] For example, in Figure 2 In this design, the cabinet 210 of the rack 200 has a cuboid structure, with its length (X), width (Y), and height (Z) directions being the same as those of the rack 200. The cabinet 210 supports and accommodates the computing nodes 220 and the power supply frame. Multiple computing nodes 220 are arranged at intervals along the height (Z) direction of the cabinet 210.

[0064] To improve the power conversion efficiency of server racks, centralized power supply has become the main power supply method for server racks. For example, in related technologies, the traditional method of configuring a power module for each computing node individually has been replaced by configuring a centralized power module on the server rack and directly supplying power to each computing node through a power bus.

[0065] Centralized power supply reduces the overall number of power modules, thereby lowering system costs and improving the conversion efficiency of the power modules.

[0066] For example, refer to Figure 3a , Figure 3a This is a schematic diagram of the planar structure of a cabinet provided in an embodiment of this application. Figure 1 .

[0067] exist Figure 3a The cabinet 200 includes a power supply frame 310, a power bus 320, and at least one computing node 220.

[0068] The power supply frame 310 is located above the cabinet 200, and the power supply frame 310 is connected to the power supply via a power cable.

[0069] The power supply frame 310 can provide power to each computing node 220 via the power bus 320.

[0070] Specifically, the power supply frame 310 can convert the voltage of the power supply into a voltage that is compatible with the computing node 220 before supplying power to the computing node 220.

[0071] In some implementations, the power bus 320 is electrically connected to the power frame 310, and the power bus 320 extends along the height direction Z of the cabinet 200 to be electrically connected to a plurality of computing nodes 220.

[0072] The maximum power supply distance of the power supply frame 310 is the height of the entire cabinet 200.

[0073] Reference Figure 3b , Figure 3b This is a schematic diagram of the planar structure of a cabinet provided in an embodiment of this application. Figure 2 .

[0074] exist Figure 3b The cabinet 200 includes a power supply frame 310, a power bus 320, and at least one computing node 220.

[0075] The power supply frame 310 is located in the middle of the cabinet 200, and the power supply frame 310 is connected to the power supply via a power cable.

[0076] The power supply frame 310 can provide power to each computing node 220 via the power bus 320.

[0077] The maximum power supply distance of the power supply frame 310 is half the height of the entire cabinet 200.

[0078] Reference Figure 3c , Figure 3c This is a schematic diagram of the planar structure of a cabinet provided in an embodiment of this application.

[0079] exist Figure 3c In the rack 200, there are power supply frame 311, power bus 320, power supply frame 312 and at least one computing node 220.

[0080] Power supply frame 1 311 is located above the rack 200, and power supply frame 2 312 is located below the rack 200. Power supply frame 1 311 and power supply frame 2 312 are respectively connected to the power supply via power cables.

[0081] Power supply frame 1 311 and power supply frame 2 312 can work together to provide power to each computing node 220 via power bus 320.

[0082] Among them, the maximum power supply distance between power supply frame 1 311 and power supply frame 2 312 is half the height of the entire cabinet 200.

[0083] As the power of server racks continues to increase, the current carrying capacity required by the power bus continues to increase, resulting in a continuous increase in the size and heat generation of the power bus.

[0084] In related technologies, power buses mainly rely on natural heat dissipation or the cooling system of computing nodes for heat dissipation. When the power of the cabinet increases to hundreds of kilowatts or more, the above-mentioned heat dissipation methods are no longer effective in reducing the temperature, which leads to the increasing complexity and cost of power bus design.

[0085] To address the aforementioned technical problems, this application provides a cabinet and computing device. By improving the power supply frame within the cabinet, the actual current path length of the power bus in the cabinet can be reduced, thereby reducing the heat generated by the power bus, which in turn reduces the size of the power bus and lowers the design complexity and cost of the power bus.

[0086] The cabinet provided in the embodiments of this application will be described in detail below through specific implementation methods. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar content will not be described again in different embodiments.

[0087] Reference Figure 4 , Figure 4 This is a schematic diagram of the planar structure of a cabinet provided in an embodiment of this application. Figure 4 .

[0088] In some embodiments, the cabinet 400 may include a power supply frame 410 and a power bus 420.

[0089] The power supply frame 410 is disposed on the side of the cabinet 400 along a first direction, which is the height direction of the cabinet 400.

[0090] The power supply frame 410 is set along the height of the rack 400 on the side of the rack 400. This layout can make full use of the space inside the rack and provide greater flexibility for the layout of computing nodes inside the rack.

[0091] The power bus 420 is close to the power frame 410, and the horizontal distance between the power bus 420 and the power frame is less than a first threshold.

[0092] Optionally, the specific value of the first threshold can be determined comprehensively based on factors such as the actual size of the cabinet 400, power transmission requirements, and heat dissipation needs. By bringing the power bus 420 closer to the power frame 410, the average distance between the power frame 410 and the computing node can be effectively shortened, thereby reducing the length of the actual flow path of the power bus 420.

[0093] The power supply frame 410 includes multiple interfaces that are connected to the power bus 420 to ensure stable and efficient power transmission.

[0094] The rack 400 contains at least one computing node 430, and each computing node 430 is connected to the power bus 420.

[0095] Understandably, in traditional rack layouts, the power supply frame is far from the compute nodes, resulting in a long power bus. A longer power bus not only increases power loss during transmission but also generates more heat, requiring additional cooling measures to ensure normal device operation. However, in the layout of this embodiment, the actual current path length of the power bus 420 is reduced, according to Joule's law (Q = I...). 2 Rt, where Q is heat, I is current, R is resistance, and t is time, means that with a constant current and resistance, a shorter current path length means a shorter resistance R, thus reducing the heat generated by the power bus 420. This reduction in heat generation allows for a smaller power bus design, reducing material usage and lowering the design complexity and cost of the power bus.

[0096] In this embodiment, by placing the power supply frame on the side of the cabinet and placing the power bus close to the power supply frame, the average distance between the power supply frame and the computing node can be effectively shortened, and the length of the actual current path of the power bus can be reduced. This can reduce the heat generation of the power bus, thereby reducing the size of the power bus and lowering the design complexity and cost of the power bus.

[0097] Optionally, in some embodiments, the length L of the power supply frame 410 in the first direction satisfies the following condition:

[0098] k×H<L<H;

[0099] Where H is the height of the rack (400mm), and 0.5 < k < 1.

[0100] Understandably, when the value of k is between 0.5 and 1, the length L of the power supply frame 410 is at least greater than 0.5 times the rack height and at most less than the rack height. That is, the length of the power supply frame 410 will not be too short (at least half the rack height) nor too long (not exceeding the rack height).

[0101] In some implementations, the appropriate power supply frame length L can be selected based on the number and layout requirements of the computing nodes within the rack 400. For example, for server racks, due to the large number of servers and high power supply requirements, a larger k value can be selected to make the length of the power supply frame 410 close to the rack height to provide sufficient interfaces; while for network racks, with relatively fewer devices, a smaller k value can be selected.

[0102] In the above embodiments, by limiting the length of the power supply frame 410, the average distance between the power supply frame and each computing node can be kept within a small range, thereby reducing the length of the actual current path of the power bus.

[0103] In some implementations, the first threshold d satisfies the following condition:

[0104] 0 < d < 0.5 × W;

[0105] Where W represents the width of the 400mm rack.

[0106] In the above embodiments, by reasonably controlling the horizontal distance between the power bus 420 and the power frame 410, the length of the power transmission path can be ensured to be within a reasonable range. This avoids both overheating problems and operational inconvenience due to excessively close distances, and increased power transmission losses due to excessively long distances.

[0107] In some embodiments, the center position of the power supply frame 410 in the first direction is the same as the center position of the cabinet 400 in the first direction.

[0108] The center position of the power supply frame 410 in the first direction is the same as the center position of the cabinet 400 in the first direction, which means that the power supply frame 410 is at the same distance from the bottom and top of the cabinet.

[0109] In the above embodiments, placing the power supply frame 410 at the center of the side of the cabinet 400 can help shorten the average distance from the power supply frame 410 to each computing node.

[0110] In some embodiments, the power supply frame 410 is disposed on any one side of the cabinet 400 along a first direction.

[0111] In the above embodiments, the power supply frame 410 is arranged along the height of the rack, which helps to save space in the vertical direction of the rack and allows more computing nodes to be installed without increasing the height of the rack.

[0112] In some embodiments, the plurality of interfaces are evenly distributed on the power frame 410 along the first direction.

[0113] The aforementioned interfaces can be arranged sequentially along the height of the rack on the power supply frame 410 at certain intervals. This orderly arrangement can distribute the power supply load. When multiple computing nodes are connected to the power supply simultaneously, the evenly distributed interfaces ensure that the current load borne by each interface is relatively balanced, avoiding problems such as interface overheating and damage caused by excessive local load, and improving the stability of power supply.

[0114] In some implementations, the power supply frame 410 includes multiple power modules, with different power modules connected to different interfaces.

[0115] Optionally, each power module within the power supply frame 410 can consist of an input filtering circuit, a power conversion circuit, an output filtering circuit, and a control and protection circuit. The input filtering circuit filters out noise and interference signals from the input power supply, ensuring the quality of the power entering the module. The power conversion circuit, the core component, is responsible for converting the input electrical energy into voltage and current suitable for the equipment. The output filtering circuit further smooths the output voltage, reducing ripple and noise. The control and protection circuit monitors the module's operating status in real time and takes timely protective measures, such as overcurrent protection, overvoltage protection, and short-circuit protection, in case of abnormalities.

[0116] Optionally, users can select different types and quantities of power modules according to their actual needs, flexibly configuring the output capacity of the power supply chassis 410. For example, in the early stages of data center construction, some power modules can be installed to meet basic needs. As business grows and the number of devices increases, new modules can be added gradually to expand the power capacity.

[0117] In some implementations, the number m of the above interfaces satisfies the following condition:

[0118] 1 < m < n;

[0119] Where n is the number of computing nodes mentioned above.

[0120] In the above embodiments, by rationally planning the number of interfaces, unnecessary interface redundancy is avoided, and the manufacturing and maintenance costs of the power supply frame 410 are reduced.

[0121] This application also provides a computing device, which includes the cabinet provided in the above embodiments.

[0122] Optionally, the aforementioned computing device may include one or more server racks.

[0123] The computing device provided in this application embodiment can help reduce the design complexity and cost of computing devices.

[0125] It is understandable that the division of modules in the aforementioned computing device is merely a logical functional division. Each function can correspond to a functional module, or two or more functions can be integrated into one functional module. In actual implementation, all or some modules can be integrated into one physical entity, or they can be distributed across different physical entities.
