Description

Technical Field

[0001] This utility model relates to the field of side panel connection technology, and specifically provides a novel data center enclosure side panel. Background Technology

[0002] With the rapid growth of global computing power, the world has entered the era of intelligent computing.

[0003] To meet the ever-increasing demand for computing power, the scale of data center construction is constantly expanding. Modular data centers, due to their standardization, prefabrication, rapid deployment, and green and low-carbon characteristics, have experienced rapid development. Currently, the conventional practice for the side panels of modular data center enclosures is to directly weld the side panels to the surrounding enclosure frame. This rigid connection method allows the side panels and the enclosure frame to work together under horizontal loads, thus providing the side panels with significant lateral stiffness. However, simulating the lateral stiffness of the side panels is complex. In enclosure structural calculations, for the sake of simplicity, the stiffness provided by the side panels is often ignored, making it difficult to guarantee the accuracy of structural calculations and posing certain safety hazards.

[0004] In this situation, the diversity of owner requirements leads to the diversity of room partitions (i.e., the arrangement of cabinet side panels), which in turn causes uneven stiffness distribution, thus causing the complexity of the overall structural stress of the modular data center, which is detrimental to the standardization, modularization and rapid expansion of the modular data center. Summary of the Invention

[0005] This utility model addresses the shortcomings of the prior art by providing a novel modular data center enclosure side panel that is rationally designed, simple in structure, safe to use, allows for flexible connections, and reduces horizontal stiffness.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A novel modular data center enclosure side panel includes a side panel surface, a top beam at the top of the side panel surface, a bottom beam at the bottom, and columns on both sides, wherein the columns are connected to the side panel surface through deep recesses; The deep recess includes two steel plates on both sides and a bottom plate connecting the two steel plates. A return spring is provided between the two steel plates. A limiting round steel is provided inside the return spring. One end of the limiting round steel is fixed to the side steel plate, and the other end is suspended.

[0007] Furthermore, the two ends of the return spring are fixed inside the side steel plate of the depth recess by pads, which are set every 300-800 mm, and the outer diameter of the return spring is 38-42 mm.

[0008] Furthermore, the thickness of the side steel plate is 1-3 mm, the distance between the two side steel plates is 68-72 mm, and the height of the side steel plate is between 70-80 mm; The diameter of the limiting round steel is 18-22 mm and the length is 38-42 mm.

[0009] Furthermore, both the top beam and the bottom beam are fixed to the side plate surface via a sliding groove, and a polytetrafluoroethylene plate is provided in the sliding groove, with the side plate surface in contact with the polytetrafluoroethylene plate.

[0010] Furthermore, the thickness of the groove is 2-4 mm, and the polytetrafluoroethylene plate is pasted inside the groove, with the pasted surface treated using a sodium-naphthalene etching solution.

[0011] Furthermore, an injection hole is provided on one outer surface of the chute, and an adhesive outlet hole is provided on the upper surface of one side of the chute, in which polyurethane foam is generated.

[0012] Furthermore, the injection holes have a diameter of 5-7 mm and are set every 350-450 mm; the dispensing holes have a diameter of 3-5 mm and are set every 350-450 mm.

[0013] Compared with existing technologies, the novel modular data center enclosure side panel of this utility model has the following outstanding advantages: The side panel of the enclosure is flexibly connected to the enclosure frame. The side panel no longer serves as a lateral force resisting component to provide horizontal stiffness. The overall stiffness of the modular data center structure no longer changes due to the change in the room division of each enclosure. Thus, the room division can be flexibly adjusted according to needs without considering its impact on the overall structural stress.

[0014] It enables standardized design of the box frame. Since the box side panel and the box frame are flexibly connected, the horizontal force is borne only by the box frame, which simplifies the stress on the box and enables standardized design of the box frame.

[0015] The standardized production of the box frame is achieved. After the standardized design of the box frame, the cross-section and dimensions of the components of each box frame are consistent, which is conducive to the rapid mass standardized processing and production in the factory, reduces the delivery time, and better leverages the advantages of prefabrication and modularization.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0020] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" generally refer to the upper, lower, left, and right as shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself.

[0021] The following is a preferred embodiment: like Figure 1-3 As shown, a novel modular data center enclosure side panel in this embodiment includes a side panel 8, a top beam 1 on the upper part of the side panel 8, a bottom beam 7 on the lower part, and columns 2 on both sides. The columns 2 are connected to the side panel 8 through a deep recess 3. The deep recess 3 includes left and right side steel plates 11 and a bottom plate 14 connecting the left and right side steel plates 11. A reset spring 4 is provided between the left and right side steel plates 11. A limiting round steel 12 is provided inside the reset spring 4. In this embodiment, one end of the limiting round steel 12 is welded to the right side steel plate 11 for fixation, and the other end is suspended.

[0022] In this embodiment, both ends of the return spring 4 are fixed inside the side steel plate 11 of the depth recess 3 by means of pads 13. One return spring 4 is provided every 500 mm inside the depth recess 3. The outer diameter of the return spring 4 is 40 mm and the length is 62 mm. The pads 13 are welded inside the side steel plate 11 and the specifications of the pads 13 are 500 mm x 500 mm x 4 mm.

[0023] In this embodiment, the side steel plate 11 has a thickness of 2 mm, the distance between the two side steel plates 11 is 70 mm, and the height of the side steel plate 11 is 75 mm. The diameter of the limiting round steel 12 is 20 mm and the length is 40 mm.

[0024] Both the top beam 1 and the bottom beam 7 are fixed to the side plate surface 8 through the sliding groove 5. The sliding groove 5 is provided with a polytetrafluoroethylene plate 6, and the side plate surface 8 is in contact with the polytetrafluoroethylene plate 6.

[0025] In this embodiment, the thickness of the groove 5 is 3 mm, the polytetrafluoroethylene plate 6 is pasted inside the groove 5, and the pasted surface is treated with sodium-naphthalene etching solution.

[0026] The left outer surface of the chute 5 is provided with an injection hole 9, and the upper surface of the left side of the chute 5 is provided with an adhesive outlet hole 10, in which polyurethane foam is generated.

[0027] In this embodiment, the injection hole 9 has a diameter of 6 mm and is set every 400 mm; the dispensing hole 10 has a diameter of 4 mm and is set every 400 mm.

[0028] In this embodiment, a novel modular data center enclosure side panel has a 70mm deep recess 3 with a large internal operating space, facilitating necessary manual grinding, welding, and painting operations. The 75mm deep recess 3 can effectively reduce the horizontal support effect of the columns on the enclosure side panel surface, thereby reducing the contribution of the enclosure side panel surface to horizontal stiffness.

[0029] Because the deformation of the deep recess 3 is irreversible, to prevent excessive plastic deformation of the recess during transportation, hoisting, and exposure to wind and seismic loads, a return spring 4 is installed every 500mm inside the deep recess 3. The return spring 4 has a limiting round steel 12 welded inside. The return spring 4 has an outer diameter of 40mm and a length of 62mm, with 500mm x 500mm x 4mm pads 13 welded to both ends. The pads 13 are welded to the side steel plates 11 on both sides of the deep recess 3 using fillet welds.

[0030] The main purpose of the return spring 4 is to restore the shape and dissipate energy within the elastic deformation range of the deep notch 3. The limiting round steel 12 has a diameter of 20mm and a length of 40mm and is placed in the middle of the return spring 4 to limit excessive deformation of the deep notch 3 and keep it within the elastic range.

[0031] To ensure that the side panel of the box can deform well, in addition to setting deep recesses 3 at both ends of the side panel 8, it is also necessary to release the constraint of the box frame on the upper and lower ends of the side panel 8. The side panel 8 is limited by setting sliding grooves 5 at the upper and lower ends of the side panel 8. The steel plate of the sliding groove 5 is 3mm thick.

[0032] To facilitate the installation of the side panel 8, the slide groove 5 is divided into two parts. After the side panel 8 is installed in the slide groove 5, the two parts of the slide groove 5 are welded together as a whole, and then the slide groove 5 is fixed to the top and bottom beams of the box body by welding. To ensure that the upper and lower ends of the side panel 8 can slide, the inside of the slide groove 5 needs to be sufficiently smooth. Therefore, a polytetrafluoroethylene (PTFE) plate 6 is installed inside the slide groove 5. PTFE material has the characteristics of low coefficient of friction (0.05~0.1), excellent corrosion resistance (resistant to strong acids, strong alkalis, oxidants, etc.), excellent aging resistance, and wide temperature resistance (not brittle at low temperatures and not softened at high temperatures), which can well ensure the sliding of the side panel. At the same time, because PTFE has a very low surface energy, conventional methods cannot be used to bond it to the slide groove. A sodium-naphthalene etching solution is used to treat the bonding surface to increase the surface energy and roughness of the PTFE bonding surface, so that it can be wetted by the adhesive. The adhesive used to bond the PTFE is an epoxy resin type, which has a good bonding effect on plastics with low surface energy. The above methods can solve the problem of effective sliding at both ends of the side panel 8 of the box, and achieve flexible connection between the upper and lower ends of the side panel 8 of the box.

[0033] The above methods have achieved effective deformation and sliding around the side panel 8. The gaps within the sliding groove 5 need to be sealed to ensure the overall thermal insulation and sound insulation performance of the enclosure. The sealing material is polyurethane foam, which has excellent thermal insulation performance, good sealing and filling properties, various molding methods, and good durability.

[0034] Taking the lower groove 5 of the side panel 8 as an example, an injection hole 9 is provided on the outer side of the groove 5, and an adhesive outlet hole 10 is provided on the top surface of the groove 5. The adhesive outlet hole 10 also serves as a vent. The diameter of the polyurethane foam injection hole 9 is 6mm, and the spacing is 400mm; the diameter of the adhesive outlet hole 10 is 4mm, and the spacing is 400mm. The position of the adhesive outlet hole 10 is in the middle of the two injection holes 9 in the horizontal direction. By injecting polyurethane foam into the side injection hole 9 and observing whether adhesive comes out of the upper adhesive outlet hole 10, it can be determined whether the space inside the groove 5 is completely filled with adhesive.

[0035] This application achieves flexible connection between the left and right ends of the side panel 8 of the enclosure by using a combination of a deep notch 3, a return spring 4, and a limiting round steel 12; achieves flexible connection between the upper and lower ends of the side panel 8 of the enclosure by using a combination of a sliding groove 5, PTFE 6, and epoxy resin adhesive; and achieves sealing treatment at the flexible connection by using polyurethane foam to ensure the thermal insulation and sound insulation performance of the enclosure.

[0036] The embodiments described above are merely one preferred embodiment of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution should be included within the protection scope of this utility model.
