Description

Technical Field

[0001] This invention relates to the field of data center infrastructure construction technology, and in particular to a modular, prefabricated skid system for data centers. Background Technology

[0002] As data centers become larger and denser, prefabricated modular data centers are widely used due to their advantages such as short construction cycles and controllable quality. In traditional construction methods, large data center frames are often assembled on-site from dozens of three-dimensional skids of varying sizes. These skids are large and heavy, making it difficult to control welding deformation during factory processing. Transportation requires specialized vehicles and is subject to road height and width restrictions, resulting in high costs. On-site hoisting is difficult, and the on-site welding of large components is prone to thermal deformation due to environmental factors, further affecting the overall frame accuracy and making it difficult to meet the basic requirements for the installation of high-precision equipment in data centers.

[0003] While existing technologies attempt to integrate IT cabinets, power distribution, and air conditioning equipment into skids, using skids to connect upper and lower modules, they have not effectively solved the fundamental challenges of processing, transporting, and installing large, integrated, three-dimensional skids. These challenges include controlling deformation of large components, ensuring on-site welding accuracy, and high transportation costs. Therefore, a new solution is urgently needed that balances the structural stability, economic efficiency, and ease of construction of large data centers. Summary of the Invention

[0004] The purpose of this invention is to provide a modular prefabricated skid system for data centers and its preparation method, so as to solve the problems existing in the above-mentioned related technologies, reduce the difficulty of prefabrication, transportation and installation, and improve on-site installation efficiency, installation accuracy and scalability.

[0005] To achieve the above objectives, the present invention provides the following solution: This invention discloses a modular, prefabricated skid system for data centers, comprising: A cube block group, comprising a cube block one, a cube block two, and several cube blocks three; each of cube block one, cube block two, and cube block three includes two facing side frames, and multiple crossbeams that are detachably vertically connected to the two side frames at both ends. A support frame assembly, comprising two support squares, the two support squares being vertically arranged and facing each other; the support squares being perpendicular to the side squares; The first cube is detachably connected to the top of the two supporting frames at both ends, the second cube is detachably connected to the bottom of the two supporting frames at both ends, and the third cube is detachably connected to the middle of the two supporting frames at both ends; the supporting frames are provided with multiple mounting positions for the second cube.

[0006] In some examples, the support frame assembly further includes a mounting bracket welded to the side of the support frame facing the cube assembly, the mounting bracket being used for detachable connection of the side frame.

[0007] In some examples, the mounting bracket is a U-shaped groove with an opening facing and accommodating the vertical portion of the side frame.

[0008] In some examples, the detachable connection includes the use of bolts.

[0009] In some examples, the inner sides of the side frames and the support frames are connected to reinforcing beams.

[0010] In some examples, the crossbeam includes a first crossbeam and a second crossbeam; the two ends of the first crossbeam are respectively connected to the right angles of the two side frames, and the two ends of the second crossbeam are respectively connected to the horizontal portions of the two side frames. The first cube includes at least the first beam, and the second cube and the third cube include at least the first beam and the second beam.

[0011] In some examples, the crossbeam further includes a third crossbeam, the two ends of which are respectively connected to the vertical portions of the two side frames; the second cube and the third cube also include the third crossbeam.

[0012] In some examples, the side frame and the support frame are pre-positioned by locating pins before the detachable connection.

[0013] This invention also discloses a method for preparing a modular prefabricated skid system for data centers, comprising the following steps: The side frames, the crossbeams, and the support frames are prefabricated in the factory. The side frame, the crossbeam, and the support frame were transported to the construction site in bulk. At the construction site, the side frame and the crossbeam are first assembled to obtain cube one, cube two and cube three; then cube one, cube two and cube three are connected to the two supporting frames respectively to obtain the assembled prefabricated modular skid system for the data center.

[0014] In some examples, the assembly method at the construction site is to use bolt connections; before using bolt connections, the side frame and the support frame are pre-positioned by locating pins.

[0015] Compared with related technologies, the present invention achieves the following technical effects: In this invention, the overall structure can be disassembled into side frames, crossbeams, and support frames. On one hand, only planar processing is required during factory prefabrication, reducing processing difficulty. On the other hand, it significantly improves the utilization of transport space and reduces transportation costs during stacking and transportation. Furthermore, during on-site construction, the weight of the side frames, crossbeams, and support frames is less than that of a cube, reducing the difficulty of movement; the detachable connection prevents thermal deformation, eliminating the slow construction and thermal deformation problems associated with on-site welding, reducing dependence on different construction trades and the impact of weather, resulting in high assembly precision and construction efficiency. Moreover, due to the detachable connection method, the device can be disassembled and resold without affecting subsequent use. Furthermore, since the support frame has multiple mounting positions for cubic blocks, the number and installation positions of cubic blocks can be adjusted to flexibly adapt to the construction of different types of data centers.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The purpose of this invention is to provide a modular prefabricated skid system for data centers and its preparation method, so as to solve the problems existing in the above-mentioned related technologies, reduce the difficulty of prefabrication, transportation and installation, and improve on-site installation efficiency, installation accuracy and scalability.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-11 This embodiment provides a modular prefabricated skid system 100 for data centers, including a cube block group 1 and a support frame group 2.

[0023] The cube group 1 includes a cube 13, a cube 2 14, and several cubes 3 15. Cube 13, cube 2 14, and cube 3 15 each include two facing side frames 11, and multiple crossbeams 12 that are detachably vertically connected to the two side frames 11 at both ends.

[0024] The support frame group 2 includes two support frames 21, which are vertically arranged and face each other. The support frames 21 are perpendicular to the side frames 11.

[0025] Specifically, cube 13 is detachably connected at both ends to the top of the two supporting frames 21, cube 24 is detachably connected at both ends to the bottom of the two supporting frames 21, and cube 35 is detachably connected at both ends to the middle of the two supporting frames 21. The middle refers to the area between the top and bottom, including but not limited to the center position. Multiple mounting positions for cube 24 are provided on the supporting frames 21.

[0026] The principle of the prefabricated modular skid system 100 used in this embodiment for data centers is as follows: Current technology involves prefabricating cubic blocks in a factory using welding, then transporting the blocks to the construction site for welding and assembly. However, this process has several drawbacks. First, ensuring diagonal dimensional accuracy during welding is difficult, making factory prefabrication challenging. Second, transporting the blocks requires significant space and incurs high costs. Furthermore, on-site welding necessitates hoisting and a large workforce, leading to high construction difficulty and low efficiency. Finally, the blocks cannot be easily disassembled after on-site welding, limiting their recycling value.

[0027] In this embodiment, the overall structure can be disassembled into side frames 11, crossbeams 12, and support frames 21. On the one hand, only planar processing is required during factory prefabrication, reducing processing difficulty. On the other hand, it greatly improves the utilization of transport space and reduces transportation costs during stacking and transportation. Moreover, during on-site construction, the weight of the side frames 11, crossbeams 12, and support frames 21 is less than the weight of a cube, reducing the difficulty of movement; the detachable connection prevents thermal deformation, eliminating the slow construction and thermal deformation problems associated with on-site welding, reducing dependence on different construction trades and the impact of weather, resulting in high assembly precision and high construction efficiency. Furthermore, due to the detachable connection method, the device can be disassembled and resold without affecting subsequent use. Moreover, since the support frame 21 has multiple mounting positions for cubic blocks 14, the number and installation positions of cubic blocks 15 can be adjusted to flexibly adapt to the construction of different types of data centers.

[0028] After the modular, prefabricated skid system 100 for data centers is assembled on-site, cubes 2 (14) and 3 (15) can serve as support for the equipment. Lower-level equipment can be placed on cube 2 (14), and upper-level equipment can be placed on cube 3 (15).

[0029] Reference Figure 2 The modular, prefabricated skid system 100 used in data centers is typically used in batches to form clusters. Figure 2 The overall dimensions of the structure on display are 12.5 meters long, 9.5 meters wide, and 7.5 meters high, but the actual dimensions may vary.

[0030] In some examples, the support frame group 2 also includes a mounting bracket 22, which is welded to the side of the support frame 21 facing the cube group 1, and the mounting bracket 22 is used for detachable connection of the side frame 11.

[0031] Because the supporting frame 21 bears a large load, if the side frame 11 is directly fixed to the supporting frame 21 using bolts 3, corresponding bolt holes 31 need to be made in the vertical part of the supporting frame 21, which would compromise the integrity of the structure, affect its strength, and pose a safety risk. This is especially true when multiple mounting positions for cubic blocks 14 are provided on the supporting frame 21; the reduction in structural strength caused by opening holes in multiple mounting positions is even more pronounced.

[0032] By welding mounting brackets 22 onto the vertical portion of the supporting frame 21, the corresponding mounting holes can be directly set on the mounting brackets 22, avoiding structural damage to the supporting frame 21. Even with multiple mounting positions for cubic blocks 24, the increased number of mounting brackets 22 will not significantly affect the overall load-bearing capacity, greatly increasing the number of redundant mounting positions for cubic blocks 24 and improving the flexibility of actual installation.

[0033] In some examples, the mounting bracket 22 is a U-shaped groove with an opening facing and accommodating the vertical portion of the side frame 11.

[0034] Both inner walls of the U-shaped groove contact and limit the vertical portion of the side frame 11, bearing the horizontal interaction force. Therefore, the fasteners connecting the U-shaped groove and the side frame 11 mainly bear the vertical shear force, avoiding the combined force caused by horizontal loads that could lead to fastener loosening and failure. Furthermore, by restricting the horizontal movement of the side frame 11, the assembly difficulty is reduced; the vertical portion of the side frame 11 only needs to slide up and down along the U-shaped groove to the specified height before the fasteners can be installed for assembly.

[0035] In some examples, detachable connections include bolted connections.

[0036] The bolted connection here refers to a detachable fixed connection achieved by locking the bolt 3 with the nut.

[0037] In some examples, the inner sides of the side frame 11 and the support frame 21 are connected with reinforcing beams.

[0038] Strengthening beams can improve structural strength, and their direction can be the length, width, or diagonal of the rectangle in which they are located.

[0039] In some examples, the crossbeam 12 includes a first crossbeam 121 and a second crossbeam 122. The two ends of the first crossbeam 121 are respectively connected to the right angles of the two side frames 11, and the two ends of the second crossbeam 122 are respectively connected to the horizontal parts (non-right angle positions) of the two side frames 11.

[0040] Cube 13 includes at least beam 121, and cube 2 14 and cube 3 15 include at least beam 121 and beam 2 122.

[0041] By setting up crossbeam 2 122, cube blocks 2 14 and 3 15 can improve load-bearing capacity and reduce the size of the top gap, thereby better supporting the equipment above.

[0042] Since cube 13 is located at the top of support frame 21, it only serves to connect the tops of the two support frames 21 and does not need to support equipment. Therefore, there is no need to install crossbeam 2 122, so as to save materials and reduce weight.

[0043] In some examples, beam 12 also includes beam 3 123, the two ends of which are connected to the vertical portions (non-right angle positions) of the two side blocks 11. Cube 2 14 and cube 3 15 also include beam 3 123.

[0044] The crossbeam 3123 is not located on top of the corresponding cubic block, so it does not serve to support the equipment, but only to strengthen the structure.

[0045] In some examples, the side frame 11 and the support frame 21 are pre-positioned by locating pins before the detachable connection.

[0046] It should be noted that fasteners such as bolts 3 need to be installed one by one. Before installation, by passing the positioning pin through the positioning pin holes on the side frame 11 and the support frame 21 at the same time, it can be determined that the relative position of the side frame 11 and the support frame 21 remains unchanged, and the positioning pin holes can be removed later.

[0047] The locating pin hole can be a bolt hole 31, or a separate pin hole can be provided. To ensure structural strength as much as possible, the locating pin hole can be a bolt hole 31, and the locating pin can be removed when installing the bolt 3 at the corresponding position. To improve assembly accuracy, the locating pin hole can be a separate pin hole.

[0048] In some examples, the horizontal part of the side frame 11 is a square steel 111, and the vertical part of the side frame 11 is a bent sheet metal part 112, which are welded together.

[0049] Square steel 111 extends along its length to both ends of the side frame 11. For a side frame 11, the number of square steel 111 can be two or more. When the number of square steel 111 is more than two, the distance between two adjacent square steel 111 is the length of the bent sheet metal part 112.

[0050] For example, both cube 13 and cube 2 14 include two square steel bars 111 and four bent sheet metal parts 112, with the four bent sheet metal parts 112 being evenly spaced. Cube 3 15 includes three square steel bars 111 and eight bent sheet metal parts 112. The top and middle square steel bars 111 are connected by four evenly spaced bent sheet metal parts 112, and the middle and bottom square steel bars 111 are connected by four evenly spaced bent sheet metal parts 112.

[0051] For example, cube 13, cube 2 14, and cube 3 15 each include four crossbeams 121, with the four crossbeams 121 corresponding to the positions of the four edges. Cube 2 14 and cube 3 15 each include two crossbeams 122, the ends of which are connected to the trisection points of the uppermost square steel 111. Cube 2 14 includes two crossbeams 123, the two ends of which are connected to the two middle square steel 111s respectively.

[0052] In some examples, the horizontal part of the supporting frame 21 is square steel 211, and the vertical part of the supporting frame 21 is square steel 212. The two ends of square steel 211 are respectively connected to two square steel 3 212 by bolts 3.

[0053] For example, the length of square steel 211 is the same as the length of crossbeam 12 and they are horizontally aligned. The number of layers of square steel 211 is the same as the number of layers of crossbeam 12. The end of square steel 111 is connected to square steel 3 212 by bolts 3.

[0054] For example, the cross-sectional profiles of square steel 111, square steel 211, and square steel 3212 are all square with a side length of 100mm, and the width of the bent sheet metal part 112 is 100mm.

[0055] For example, the end of the crossbeam 12 is an end face formed by bending, and the end face is provided with through holes for mounting bolts 3. The ends of square steel 111, square steel 211, and square steel 3 212 are end faces formed by welding cover plates, and the end faces of square steel 111 and square steel 211 are provided with through holes for mounting bolts 3.

[0056] For example, a bent sheet metal part 112 can be vertically arranged between two adjacent square steel bars 211. The end of the bent sheet metal part 112 is welded to the end of the adjacent square steel bar 211 so as to limit the distance between the two adjacent square steel bars 211.

[0057] For example, to facilitate the installation and removal of bolt 3, square steel 111, square steel 211, and square steel 3 212 have windows on their sides, allowing tools, bolt 3, and the operator's fingers to pass through. (Refer to...) Figure 9 , Figure 11The window shape can be rectangular. (See reference...) Figure 10 The crossbeam 12 has a bent structure with openings on its side, so there is no need to open a window.

[0058] For the side frame 11, the square steel 111 and the bent sheet metal part 112 on the inner side of the rectangular outer contour serve as reinforcing beams.

[0059] For the supporting frame 21, the square steel 211 inside the rectangular outer contour serves as a reinforcing beam.

[0060] The length and width of the side frame 11 should generally not be too large, for example, no more than 2m, to facilitate transportation.

[0061] This embodiment also provides a method for preparing a modular prefabricated skid system for data centers, which is used to prepare the above-mentioned modular prefabricated skid system 100 for data centers, and includes the following steps: The side frames 11, crossbeams 12, and support frames 21 are prefabricated in the factory. All welding processes are completed in the factory using tooling fixtures and CNC equipment to ensure that the diagonal dimensional error of the side frames 11 and support frames 21 is controlled within a high-precision range of no more than 2mm.

[0062] The side frame 11, crossbeam 12, and support frame 21 were transported to the construction site in bulk.

[0063] At the construction site, the side frame 11 and the crossbeam 12 are first assembled to obtain cube block 13, cube block 24 and cube block 35. Then, cube block 13, cube block 24 and cube block 315 are connected to the two supporting frames 21 respectively to obtain the assembled prefabricated modular skid system 100 for data centers.

[0064] The principle of the fabrication method of the prefabricated modular skid system for data centers in this embodiment is as follows: The core of this fabrication method lies in breaking down the entire structure into smaller, more precise components and assembling them precisely. Specifically, the large, complex cubic structure, which traditionally requires on-site welding, is broken down during the design and manufacturing phase into a series of easily prefabricated and transportable two-dimensional planar structures and beams 12. These units are manufactured with high precision in a controlled factory environment. Once on-site, these planar units and beams 12 are assembled in three-dimensional space using mechanical connections such as bolts 3 and locating pins, like building blocks, ultimately forming a stable main frame for the data center. This design transfers the most complex welding work from the variable conditions of the construction site to the superior conditions of the factory, significantly improving project quality and efficiency.

[0065] In some examples, the assembly method at the construction site is to use bolts 3 for connection. Before using bolts 3 for connection, the side frame 11 and the support frame 21 are pre-positioned by locating pins.

[0066] By pre-positioning, the relative positional stability of the side frame 11 and the support frame 21 is ensured during bolt 3 installation, improving installation efficiency. Accurate positioning with locating pins enables rapid alignment and installation, with the overall frame dimensional error controlled within 3mm, meeting the requirements for high-precision equipment installation and significantly increasing installation speed.

[0067] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
