Description

Technical Field

[0001] This application belongs to the field of data center technology, and more specifically, relates to an adjustable depth cabinet frame and a cabinet used in data centers. Background Technology

[0002] In data centers, server racks provide standardized installation space for equipment such as servers, switches, storage devices, and power supplies. By vertically stacking equipment in the racks, data centers can maximize the use of valuable floor space. The racks also create a relatively enclosed space, offering some protection against dust and accidental collisions, thus safeguarding the equipment inside.

[0003] In the overall planning and construction of data centers, the size of the server racks (especially the depth) directly affects the width of enclosed aisles, which not only affects the cooling effect but also has a significant impact on the design and layout of cabling, lighting, and fire protection piping.

[0004] Standard server rack depths range from 600mm to 1200mm, primarily influenced by the dimensions of hardware such as servers, switches, and storage devices. Generally, rack frames of varying depths need to be manufactured custom-made to meet different design requirements, and side panels, front doors, and rear doors are added to these frames to create a closed equipment storage space. This design makes it difficult to further reduce the production and operating costs of server racks, thus impacting the optimization of overall data center construction costs. Utility Model Content

[0005] The purpose of this application is to provide an adjustable depth cabinet frame and a server rack for data centers, aiming to solve the problem that server racks of different depths require the separate manufacture of frames and other components of different depths, resulting in high manufacturing costs.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide a cabinet frame with adjustable depth, comprising: The main frame and the extension frame are provided on the front and / or rear sides of the main frame to extend the internal space of the cabinet in the front-rear direction. The extension frame includes an extension face frame, an extension top plate disposed at the top of the extension face frame, and an extension bottom plate disposed at the bottom of the extension face frame. The extension top plate and the extension bottom plate are both arranged perpendicular to the vertical direction. The extended top plate is connected to the top of the main frame on one side away from the extended face frame, and the extended bottom plate is connected to the bottom of the main frame on one side away from the extended face frame.

[0007] Compared with the prior art, the solution shown in this application embodiment designs the main frame as a frame structure with a minimum standard depth dimension (e.g., 1m) and the extension frame as a frame structure with a unit extension depth dimension (e.g., 0.2m). If it is necessary to extend the cabinet frame in the depth direction, the extension frame can be installed on the front and / or rear side of the main frame to form cabinet frames of different depths.

[0008] Meanwhile, with the main frame dimensions fixed, the main side panels, main top panel, and main bottom panel of the main frame all adopt standard panel depth dimensions. In the extension frame, the depth dimensions of the extension top panel and extension bottom panel are also fixed. After assembly, the extension top panel and extension bottom panel are closed from the top and bottom sides respectively. In addition, since the depth dimensions of the extension frame are fixed, the depth dimensions of its corresponding extension side panels are also fixed.

[0009] Overall, by using the main frame and extension frames in tandem, the standardized design of the main frame and extension frames also drives the standardized design of related panels. During production, it is not necessary to manufacture the frames and individual panels separately according to the design requirements of different depths. It is only necessary to select the number of extension frames and related panels to be used according to the design requirements, thereby reducing the production and manufacturing cost of the cabinet.

[0010] In conjunction with the first aspect, in one possible implementation, the extended top plate includes a top plate body and two sets of top connecting longitudinal beams; The two sets of top connecting longitudinal beams are respectively located on the left and right edges of the main body of the top plate, and both sets of top connecting longitudinal beams are located on the lower side of the main body of the top plate. One end of the top connecting longitudinal beam is fitted and connected to the extended face frame, and the other end is fitted and connected to the main frame.

[0011] In some embodiments, the top plate body is bent downward on one side of the main frame away from the main frame to form a top plate connecting flange, and the top plate connecting flange is fitted and connected to the top crossbeam of the extension frame.

[0012] In some embodiments, the top connecting longitudinal beam includes a longitudinal beam main board and two sets of longitudinal beam end plates. The longitudinal beam main board is perpendicular to the main body of the top plate, and the two sets of longitudinal beam end plates are respectively disposed at the front and rear ends of the longitudinal beam main board, and are both disposed perpendicular to the front and rear direction. The longitudinal beam end plates are fitted and connected to the extension face frame or the main frame.

[0013] In some embodiments, the lower edge of the main longitudinal beam is bent inward to form a longitudinal beam reinforcing plate, and the longitudinal beam end plate is connected to the longitudinal beam reinforcing plate; the lower side of the longitudinal beam end plate extends downward to form an end plate extension plate, and the end plate extension plate is fitted and connected to the extension face frame or the main frame.

[0014] In some embodiments, the top plate body has its edge near the main frame bent downwards to form a reinforced flange.

[0015] In conjunction with the first aspect, in one possible implementation, the extended base plate includes a base plate body and two sets of bottom connecting longitudinal beams; The two sets of bottom connecting longitudinal beams are respectively located on the left and right edges of the base plate body, and both sets of bottom connecting longitudinal beams are located on the lower side of the base plate body. One end of the bottom connecting longitudinal beam is fitted and connected to the extended face frame, and the other end abuts against the main frame.

[0016] In some embodiments, the extended face frame includes a top crossbeam, a bottom crossbeam disposed below the top crossbeam, and two sets of extended vertical beams supported between the top crossbeam and the bottom crossbeam; The base plate body has a first base plate notch at one corner facing the extension vertical beam, and the end of the bottom crossbeam has a crossbeam notch corresponding to the first base plate notch. The first base plate notch and the crossbeam notch are joined together to form a splicing groove for accommodating the extension vertical beam. The end of the bottom connecting longitudinal beam is fitted and connected to the corresponding side of the extended vertical beam.

[0017] In conjunction with the first aspect, in one possible implementation, an auxiliary reinforcing beam is provided to support the extension face frame and the main frame, the auxiliary reinforcing beam being located between the extension top plate and the extension bottom plate.

[0018] Secondly, embodiments of this application also provide a cabinet for a data center, including the aforementioned cabinet frame with adjustable depth dimensions.

[0019] Compared with the prior art, the solution shown in this application adopts the cabinet frame with adjustable depth dimensions. By standardizing the design of the main frame and extension frame of the cabinet frame, the main side plate, main top plate and main bottom plate related to the main frame, as well as the extension side plate related to the extension frame, and other components are also standardized, which reduces the production and manufacturing cost of the cabinet and thus helps to reduce the overall construction cost of the data center.

Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a few" means two or more, unless otherwise explicitly specified.

[0026] The standard rack depth is mainly affected by the size of hardware devices such as servers, switches, and storage devices. Taking servers as an example, the depth of general-purpose servers is usually between 700mm and 900mm, while the depth of high-performance servers (such as graphics processing servers) is usually between 1000mm and 1200mm. The usable depth of the rack must be greater than the depth of the equipment and allow space for the bending radius of cables (power cords and data cables).

[0027] Depending on the different depth dimensions of the equipment, each component of the rack frame, such as the longitudinal beams, side panels, and top panels extending along the depth direction, needs to be designed and manufactured separately. This prevents the formation of a standardized component system, resulting in high production costs and directly impacting the overall construction cost of the data center.

[0028] To resolve the above issues, please refer to the following: Figures 1 to 5 The adjustable depth cabinet frame provided in this application will now be described. The adjustable depth cabinet frame includes a main frame 100 and an extension frame 200. The extension frame 200 is provided on the front and / or rear sides of the main frame 100 to extend the internal space of the cabinet in the front-back direction. The extension frame 200 includes an extension faceplate 210, an extension top plate 220 located at the top of the extension faceplate 210, and an extension bottom plate 230 located at the bottom of the extension faceplate 210. Both the extension top plate 220 and the extension bottom plate 230 are perpendicular to the vertical direction. The side edge of the extension top plate 220 facing away from the extension faceplate 210 is connected to the top of the main frame 100, and the side edge of the extension bottom plate 230 facing away from the extension faceplate 210 is connected to the bottom of the main frame 100, thereby extending the internal space of the cabinet in the front-back direction.

[0029] In this embodiment, the layout of the extension frame 200 and the main frame 100 is illustrated as follows: the extension frame 200 is installed on the front side of the main frame 100, or on the rear side of the main frame 100, or on both the front and rear sides of the main frame 100. Whether to provide the extension frame 200, and the specific number of extension frames 200, can be selected according to actual design requirements.

[0030] In this embodiment, the main frame 100 is designed with a minimum standard depth dimension, and the extension frame 200 is designed with a unit extension depth dimension. The unit extension depth dimension refers to half of the difference between the maximum design depth dimension and the minimum standard depth dimension of the cabinet. Therefore, if the extension frames 200 are installed on the front and rear sides of the main frame 100 respectively, the depth dimension of the cabinet frame at this time is the maximum design depth dimension.

[0031] Compared with the prior art, the adjustable depth cabinet frame provided in this application designs the main frame 100 as a frame structure with a minimum standard depth dimension (e.g., 1m) and the extension frame 200 as a frame structure with a unit extension depth dimension (e.g., 0.2m). If it is necessary to extend the cabinet frame in the depth direction, the extension frame 200 can be installed on the front and / or rear side of the main frame 100 to form cabinet frames of different depths.

[0032] Meanwhile, with the dimensions of the main frame 100 fixed, the main side plates, main top plate 300, and main bottom plate 400 of the main frame 100 all adopt standard plate depth dimensions. In the extension frame 200, the depth dimensions of the extension top plate 220 and extension bottom plate 230 are also fixed. After assembly, the extension top plate 220 and extension bottom plate 230 are closed from the top and bottom sides, respectively. Furthermore, since the depth dimensions of the extension frame 200 are fixed, the depth dimensions of its corresponding extension side plates are also fixed.

[0033] Overall, by adopting the main frame 100 and the extension frame 200 working together, the standardized design of the main frame 100 and the extension frame 200 also promotes the standardized design of related panels. During production, it is not necessary to manufacture the frame and each panel separately according to the design requirements of different depths. It is only necessary to select the number of extension frames 200 and the number of related panels according to the design requirements. This also helps to shorten the assembly time and reduce the production and manufacturing cost of the cabinet.

[0034] In some embodiments, see Figures 1 to 3 The extended top plate 220 includes a top plate body 221 and two sets of top connecting longitudinal beams 222. The two sets of top connecting longitudinal beams 222 are respectively located on the left and right edges of the top plate body 221, and both sets of top connecting longitudinal beams 222 are located on the lower side of the top plate body 221. One end of the top connecting longitudinal beam 222 is fitted and connected to the extended face frame 210, and the other end is fitted and connected to the main frame 100. The two sets of top connecting longitudinal beams 222 are integrally formed or welded to the top plate body 221, which improves the connection strength between the top plate body 221 and the top connecting longitudinal beams 222.

[0035] In this embodiment, top connecting longitudinal beams 222 are respectively provided on the left and right sides of the top plate body 221, which can produce the following beneficial effects: First, the end area of ​​the top connecting longitudinal beams 222 is relatively large, which can provide a connection surface for connecting with the extension frame 210 and the main frame 100, ensuring the reliability of assembly. Second, when the top plate body 221 is subjected to loads perpendicular to the plate surface, it is prone to bending deformation. The top connecting longitudinal beams 222 at the edge are equivalent to providing a skeleton for the top plate body 221, increasing the bending stiffness of the top plate body 221. At the same time, the top connecting longitudinal beams 222 can also effectively transfer the load acting on the top plate body 221 to the main extension frame 210 and the main frame 100, avoiding stress concentration at the edge of the top plate body 221, and improving the overall load-bearing limit of the extension top plate 220. Third, while meeting the overall structural strength of the extension top plate 220, the top plate body 221 adopts a thin plate design, achieving the maximum structural efficiency with the least amount of material, avoiding the design of the extension top plate 220 as too thick and heavy, which is conducive to achieving lightweight design.

[0036] In some specific embodiments of the top plate body 221, see Figure 3 The top plate body 221 bends downwards at one edge away from the main frame 100 to form a top plate connecting flange 223, which is fitted and connected to the top crossbeam 211 of the extension frame 210. In this embodiment, the top plate connecting flange 223 forms an additional connection area between the two sets of top connecting longitudinal beams 222 and the extension frame 210, enhancing the bonding strength between the top plate body 221 and the extension frame 210. This allows the extension frame 200 to maintain its structural stability better when transported as a component independent of the main frame 100 and assembled with the main frame 100, preventing deformation and damage to the extension frame 200 during transport and assembly, and improving the safety and reliability of cabinet-related construction. In addition, the top plate connecting flange 223 also reinforces the front edge of the top plate body 221, preventing the top plate body 221 from bending after installation with the extension frame 210.

[0037] In some specific embodiments of the top connecting longitudinal beam 222, see [reference needed]. Figure 3 The top connecting longitudinal beam 222 includes a main longitudinal beam 2221 and two sets of longitudinal beam end plates 2222. The main longitudinal beam 2221 is perpendicular to the main body of the top plate 221. The two sets of longitudinal beam end plates 2222 are respectively located at the front and rear ends of the main longitudinal beam 2221, and are both perpendicular to the front and rear direction. The longitudinal beam end plates 2222 are fitted and connected to the extension frame 210 or the main frame 100. In this embodiment, the main longitudinal beam 2221 and the main body of the top plate 221 are integrally formed by stamping and bending, and the longitudinal beam end plates 2222 and the main body of the top plate 221 are integrally formed by stamping and bending. The main longitudinal beam 2221 and the longitudinal beam end plates 2222 are welded together.

[0038] The longitudinal beam main body 2221, longitudinal beam end plate 2222, and top plate main body 221 work together to form a box-like structure. Utilizing the high structural strength of the box-like structure, reinforcement is provided at the edges of the top plate main body 221. Meanwhile, the structure connecting the top to the longitudinal beam 222 is relatively simple, using less material, and can better meet the design requirements of lightweight and low cost.

[0039] In this embodiment, the longitudinal beam end plate 2222 is provided with connection points (e.g., connection holes) that connect to the extension face frame 210 or the main frame 100. Furthermore, the longitudinal beam end plate 2222 is provided with multiple connection points, and the multiple connection points are distributed at intervals along the vertical direction to improve the bonding strength between the longitudinal beam end plate 2222 and the extension face frame 210 or the main frame 100.

[0040] Based on the above embodiments, see Figure 3 The lower edge of the longitudinal beam main plate 2221 is bent inward to form a longitudinal beam reinforcing plate 2223. The lower side of the longitudinal beam end plate 2222 extends downward to form an end plate extension plate 2224. The longitudinal beam end plate 2222 is connected to the longitudinal beam reinforcing plate 2223. The end plate extension plate 2224 is fitted and connected to the extension face frame 210 or the main frame 100. The longitudinal beam end plate 2222 and the longitudinal beam reinforcing plate 2223 are welded together.

[0041] In this embodiment, the longitudinal beam reinforcing plate 2223 reinforces the lower edge of the longitudinal beam main plate 2221, further enhancing the bending strength of the longitudinal beam main plate 2221 and dispersing the load acting on the top plate body 221, which is beneficial to improving the overall bearing capacity of the top connecting longitudinal beam 222. After the longitudinal beam end plate 2222 is connected to the longitudinal beam reinforcing plate 2223, the aforementioned box-shaped structure is further strengthened, enhancing the bending resistance of the extended top plate 220. On this basis, an end plate extension plate 2224 is provided on the lower side of the longitudinal beam end plate 2222, and connection points (e.g., connection holes) are provided on the end plate extension plate 2224 to connect with the extension face frame 210 or the main frame 100, improving the bonding strength between the extended top plate 220 and the extension face frame 210 or the main frame 100, and making the radial structure of the top connecting longitudinal beam 222 more compact.

[0042] This embodiment exemplifies an example of setting an end plate extension plate 2224 only on the lower side of the longitudinal beam end plate 2222 near the main frame 100. It should be understood that the end plate extension plate 2224 can also be set on the lower side of the longitudinal beam end plate 2222 near the extension frame 210. The end plate extension plates 2224 at both ends can be set simultaneously or one can be set selectively. There is no unique limitation here.

[0043] In some specific embodiments of the top plate body 221, see Figure 3The top plate 221 has its edge near the main frame 100 bent downwards to form a reinforcing flange 224. The reinforcing flange 224 is welded to the adjacent longitudinal beam end plate 2222.

[0044] In this embodiment, the reinforcing flange 224 is reinforced with the rear edge of the main body 221 of the top plate. It works in conjunction with the connecting flange 223 of the top plate and the top connecting longitudinal beam 222 to form a continuously distributed reinforcing skeleton around the main body 221 of the top plate, which promotes the overall structural strength of the extended top plate 220.

[0045] In some embodiments, see Figure 4 and Figure 5 The extended base plate 230 includes a base plate body 231 and two sets of bottom connecting longitudinal beams 232. The two sets of bottom connecting longitudinal beams 232 are respectively located on the left and right edges of the base plate body 231, and both sets of bottom connecting longitudinal beams 232 are located on the lower side of the base plate body 231. One end of the bottom connecting longitudinal beam 232 is fitted and connected to the extended face frame 210, and the other end abuts against the main frame 100. The two sets of bottom connecting longitudinal beams 232 are integrally formed or welded to the base plate body 231, which improves the connection strength between the base plate body 231 and the bottom connecting longitudinal beams 232.

[0046] In this embodiment, bottom connecting longitudinal beams 232 are respectively provided on the left and right sides of the base plate body 231, which can produce the following beneficial effects: First, the end area of ​​the bottom connecting longitudinal beams 232 is relatively large, which can provide a connection surface for connecting with the extension frame 210 and a contact surface for contact with the main frame 100, ensuring the reliability of assembly. Second, when the base plate body 231 is subjected to loads perpendicular to the plate surface, it is prone to bending deformation. The bottom connecting longitudinal beams 232 at the edge are equivalent to providing a skeleton for the base plate body 231, increasing the bending stiffness of the base plate body 231. At the same time, the bottom connecting longitudinal beams 232 can also effectively transfer the load acting on the base plate body 231 to the main extension frame 210 and the main frame 100, avoiding stress concentration at the edge of the base plate body 231 and improving the overall load-bearing limit of the extension base plate 230. Third, while meeting the overall structural strength of the extension base plate 230, the base plate body 231 adopts a thin plate design, achieving the maximum structural efficiency with the least amount of material, avoiding the design of the extension base plate 230 as too thick and heavy, which is conducive to achieving lightweight design.

[0047] In some embodiments, see Figure 1 and Figure 2The extended frame 210 includes a top crossbeam 211, a bottom crossbeam 212 located below the top crossbeam 211, and two sets of extended vertical beams 213 supported between the top crossbeam 211 and the bottom crossbeam 212. The top surface of the extended vertical beams 213 is flush with the top surface of the top crossbeam 211, and the bottom surface of the extended vertical beams 213 is flush with the bottom surface of the bottom crossbeam 212. The extended frame 210 has a simple structure and is compatible with the front shape of the main frame 100.

[0048] A first base plate notch 2311 is provided at one corner of the base plate body 231 facing the extending vertical beam 213. A corresponding crossbeam notch 2121 is provided at the end of the bottom crossbeam 212. The first base plate notch 2311 and the crossbeam notch 2121 are joined to form a splicing groove for accommodating the extending vertical beam 213. The end of the bottom connecting longitudinal beam 232 is fitted and connected to the corresponding side of the extending vertical beam 213, and the end of the top connecting longitudinal beam 222 is fitted and connected to the corresponding side of the extending vertical beam 213. By providing the first base plate notch 2311 and the crossbeam notch 2121, a splicing position (i.e., a splicing groove) corresponding to the extending vertical beam 213 is formed on the extending base plate 230, facilitating alignment between the two and thus enabling easy alignment and connection between the end of the top connecting longitudinal beam 222 and the corresponding side of the extending vertical beam 213.

[0049] Optionally, the fitting connection between the end of the top connecting longitudinal beam 222 and the corresponding side extension vertical beam 213 can be achieved by means including but not limited to fasteners (e.g., bolts).

[0050] In some embodiments, see Figure 1 and Figure 2 The main frame 100 has a main vertical beam 110 and a main bottom horizontal beam 120. Both ends of the main bottom horizontal beam 120 are connected to the bottom ends of the corresponding main vertical beam 110. A base plate 231 overlaps the main bottom horizontal beam 120, and a second base plate notch 2312 is provided at one corner of the base plate 231 facing the main vertical beam 110. The second base plate notch 2312 is used to accommodate the main vertical beam 110. In this embodiment, by providing the second base plate notch 2312, it is convenient to extend the base plate 230 to align with the main frame 100, without affecting the structure of the main frame 100.

[0051] In some embodiments, see Figure 4 and Figure 5To connect the base plate body 231 with the extension frame 210 and the main frame 100, the front and rear edges of the base plate body 231 are bent downwards to form base plate connecting flanges 233. The base plate connecting flanges 233 are fitted and connected to the top crossbeam 211 of the extension frame 210 or the bottom crossbeam 120 of the main frame 100. In addition to achieving the connection, the base plate connecting flanges 233 also strengthen the base plate body 231, preventing deformation of the base plate body 231 during assembly or use.

[0052] In some embodiments, see Figure 1 and Figure 2 An auxiliary reinforcing beam 240 supports the connection between the extension frame 210 and the main frame 100. The auxiliary reinforcing beam 240 is located between the extension top plate 220 and the extension bottom plate 230. At the support connection point between the extension frame 210 and the main frame 100, the load on the extension frame 210 can be distributed and transferred to the main frame 100 through more force transmission paths, preventing excessive stress on the extension top plate 220 or extension bottom plate 230 and thus extending the service life of the extension frame 200. Simultaneously, connection points corresponding to the extension side plates can be set on the auxiliary reinforcing beam 240 to connect and fix the middle of the extension side plates, preventing bulging after assembly.

[0053] In practice, multiple sets of auxiliary reinforcing beams 240 are provided. One set of auxiliary reinforcing beams 240 is located near the top of the extension frame 210, while another set is located in the middle of the extension frame 210. By setting auxiliary reinforcing beams 240 in these two areas, the need for support and reinforcement is met. At the same time, the number of connection points between the extension side plate and the extension frame 200 is reduced, avoiding the problem of excessive connection points leading to the accumulation of assembly errors and ultimately affecting the assembly efficiency of the extension side plate.

[0054] Based on the same inventive concept, this application also provides a cabinet for data centers, including the cabinet frame with adjustable depth as described above.

[0055] In this embodiment, the left and right sides of the main frame 100 are covered with main side panels, the top of the main frame 100 is covered with a main top plate 300, and the bottom is covered with a main bottom plate 400; similarly, the left and right sides of the extension frame 200 are covered with extension side panels.
