[0001] This utility model relates to the field of data center equipment technology, and more specifically, to a modular server rack for data centers. Background Technology

[0002] Server racks are the core carriers of data center infrastructure, used for the centralized installation, fixation, protection, and management of IT hardware such as servers, storage devices, network switches, and power / cooling modules. They also provide support functions such as cabling, heat dissipation, and monitoring. Essentially, they are standardized, modular metal frame systems that, through optimized physical structure and functional design, ensure efficient operation of the data center.

[0003] However, current server racks have the following drawbacks in actual use:

[0004] 1. Poor scalability: Fixed-size server racks need to be pre-installed during the initial construction of the data center. Later expansion requires the entire rack to be replaced or renovated, which is costly and has a long construction period.

[0005] 2. Difficult to move: The integrated cabinet is heavy and has a fixed size, making it inconvenient to move.

[0006] In view of this, the present invention provides a modular server rack for computer rooms to solve the above problems. Utility Model Content

[0007] To address the shortcomings of existing solutions, this utility model provides a modular server rack for data centers. It enables flexible expansion and efficient operation and maintenance through the rapid assembly of standardized unit cabinets, and shortens the deployment cycle through modular design.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A modular server rack for a computer room includes a top cover, unit cabinets and a base. The base has multiple sets of vertically spliced ​​unit cabinets on its upper side. The multiple sets of unit cabinets are fixedly connected to each other by connectors and connecting lugs and fastening bolts. The top cover is installed on the top of the uppermost unit cabinet.

[0010] The unit cabinet includes a protective panel, a bracket and a frame. The frame is surrounded by a protective panel on the left, right and rear sides. The frame is provided with two sets of brackets of the same specifications on the inner side. The frame is provided with multiple sets of positioning holes at equal intervals. The brackets are fixedly connected to the positioning holes by fastening bolts. The bottom of the four corners of the frame is provided with connectors. The four corners near the upper end are provided with horizontal connecting ear plates.

[0011] The bracket includes side plates, a base plate, a support plate, a cable tray, and telescopic slide rails. The base plate has side plates perpendicular to it on both the left and right sides. The front end of the side plates is bent outward at a right angle, and the bent part is connected to the positioning hole by fastening bolts. The base plate has two sets of telescopic slide rails. The support plate is fixedly connected to the upper side of the telescopic slide rails. The support plate is slidably connected to the base plate through the telescopic slide rails. A cable tray is opened on the rear side of the base plate.

[0012] Furthermore, a heat dissipation vent is provided on the rear protective plate, and a cooling fan is installed on the outside of the heat dissipation vent.

[0013] Furthermore, multiple sets of rotatable rollers are equidistantly embedded inside the side plate, and the surface of the rollers protrudes from the surface of the side plate.

[0014] Furthermore, the tray has multiple sets of through holes evenly provided for ventilation and heat dissipation, and multiple sets of spacers are evenly pasted on the surface of the tray laterally.

[0015] A slot is provided at the front end of the base plate.

[0016] Furthermore, the frame is composed of four sets of hollow square tubes, forming an overall U-shaped structure. Adjacent hollow square tubes on the left, right, and rear sides are fixedly connected by crossbars. The second connecting ear plate is fixed on the inner side of the four sets of hollow square tubes near the upper end. The connector includes a right-angle clamping plate, a first connecting ear plate, and a fastening bolt. The right-angle clamping plate is fixed on the inner side of the lower end of the hollow square tube on the frame. The first connecting ear plate is fixed on the inner side of the right-angle clamping plate and is perpendicular to it. The specifications of the first connecting ear plate are compatible with those of the second connecting ear plate. The first connecting ear plate is provided with a fastening bolt, and the lower end of the fastening bolt is fitted with a nut.

[0017] Furthermore, a top square tube is fixedly installed on the inner side of the cabinet top cover near the four corners, and the position of the top square tube corresponds to the position of the square tube on the frame. A connector is fixedly installed at the lower end of the top square tube.

[0018] The base has four corners at the top surface of the base, and the positions of the bottom square tubes correspond to the positions of the square tubes on the frame. A connecting ear plate two perpendicular to the bottom square tube is fixed on the inner side of the bottom square tube near the top.

[0019] Furthermore, the base has a cable routing hole inside for cable passage, and foot pads are fixed at the four corners of the bottom of the base.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This utility model adopts a modular design concept, and multiple unit cabinets can be vertically spliced ​​together, which solves the problem that fixed-size cabinets need to be preset in the early stage of computer room construction and that the whole system needs to be replaced or modified when the capacity is expanded later. This reduces costs, shortens the construction cycle, and facilitates assembly and disassembly, thus improving the ease of operation.

[0022] 2. Existing integrated server racks are heavy and have a fixed size, making them inconvenient to move. This modular design can break down the rack into multiple unit racks, reducing the weight and size of individual components, making it easier to load and transport by vehicles, and also facilitating handling and installation within the server room, thus improving construction efficiency.

[0023] 3. This utility model enhances air circulation inside the cabinet through the design of heat dissipation vents on the rear side panel, cooling fans, and through holes on the tray, effectively improving heat dissipation efficiency and ensuring the stable operation of servers and other equipment.

[0024] 4. In this utility model, the tray is slidably connected to the base plate via a telescopic slide rail, which facilitates the installation and disassembly of servers and other equipment. Maintenance personnel can easily pull the equipment out of the cabinet for maintenance and repair without having to operate in the narrow space inside the cabinet, thus improving maintenance efficiency.

[0025] 5. In this utility model, the unit cabinets are fixedly connected by connecting parts and connecting ear plates with fastening bolts, which enables quick positioning and connection between adjacent unit cabinets, reduces installation and disassembly time, improves the assembly efficiency of the cabinet, and ensures the stability of the connection.

Detailed Implementation

[0037] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0038] Example:

[0039] like Figures 1 to 10 As shown, a modular server rack for a computer room includes a top cover 1, unit cabinets 2 and a base 3. Multiple sets of vertically spliced ​​unit cabinets 2 are provided on the upper side of the base 3. The multiple sets of unit cabinets 2 are fixedly connected to each other by connectors 23 and connecting ear plates 251 with fastening bolts 233. The top cover 1 is installed on the top of the uppermost unit cabinet 2.

[0040] The unit cabinet 2 includes a protective plate 21, a bracket 22 and a frame 25. The protective plate 21 is provided on the outer side, left, right and rear sides of the frame 25. Two sets of brackets 22 of the same specifications are provided on the inner side of the frame 25. Multiple sets of positioning holes 27 are equally spaced on the frame 25. The brackets 22 are fixedly connected to the positioning holes 27 by fastening bolts 233. Connectors 23 are provided at the bottom of the four corners of the frame 25. Horizontal connecting ear plates 251 are fixed at the four corners near the upper end.

[0041] The bracket 22 includes side plates 221, a base plate 223, a support plate 225, a cable tray 228, and telescopic slide rails 229. The base plate 223 has side plates 221 perpendicular to it on both the left and right sides. The front end of the side plates 221 is bent outward at a right angle, and the bent part is connected to the positioning hole 27 by fastening bolts 233. The base plate 223 has two sets of telescopic slide rails 229. The support plate 225 is fixedly connected to the upper side of the telescopic slide rails 229. The support plate 225 is slidably connected to the base plate 223 through the telescopic slide rails 229. The cable tray 228 is opened on the rear side of the base plate 223. This design solves the problems of current server racks, which require pre-setting fixed-size racks in the early stage of data center construction, and later expansion requires overall replacement or modification, which is costly and has a long construction period. In addition, the integrated rack is heavy, has a fixed size, and is not convenient to move.

[0042] In this embodiment, a heat dissipation vent 26 is provided on the rear side panel 21, and a cooling fan 24 is installed on the outside of the heat dissipation vent 26. During the operation of the server, a large amount of heat is generated. The heat dissipation vent 26 on the rear side panel 21, together with the cooling fan 24, forms a forced convection cooling system. When the cooling fan 24 is working, it draws cooler air from outside the cabinet into the cabinet through the heat dissipation vent 26 and blows it toward the server and other heat-generating equipment, accelerating the flow of hot air around the equipment, quickly carrying away the heat generated by the equipment, and exhausting it through other ventilation vents in the cabinet. This effectively reduces the internal temperature of the cabinet, ensuring that the server operates stably in a suitable temperature environment and reducing the risk of equipment performance degradation, crashes, or even damage due to overheating.

[0043] In this embodiment, multiple sets of rotatable rollers 222 are equidistantly embedded inside the side plate 221, and the surfaces of the rollers 222 protrude from the surface of the side plate 221. When the server is installed, disassembled, or moved on the bracket 22, its side will contact the side plate 221, which will cause wear over time. By embedding the rotatable rollers 222, the device contacts the surface of the rollers 222. As the device moves, the rollers 222 will rotate, changing the original sliding friction into rolling friction. Since rolling friction is much less than sliding friction, the resistance experienced by the device during movement is greatly reduced, making movement easier, effectively reducing server wear, and improving the efficiency and convenience of device installation and maintenance.

[0044] In this embodiment, multiple sets of through holes 227 for ventilation and heat dissipation are evenly opened on the tray 225. The through holes 227 form air circulation channels, allowing cool air to directly contact the bottom of the server through the through holes 227, carrying away the heat generated by the server and enhancing the overall heat dissipation effect of the rack. Multiple sets of spacers 226 are evenly pasted horizontally on the surface of the tray 225. The spacers 226 can elevate the server, leaving a certain gap between its bottom surface and the tray 225. These gaps cooperate with the through holes 227 on the tray 225 to further optimize the air circulation path at the bottom of the server, which helps to improve heat dissipation efficiency.

[0045] In this embodiment, a slot 224 is provided at the front end of the base plate 223. The design of the slot 224 provides additional operating space for picking up and placing server equipment on the tray 225, making it convenient to extend and retract the tray 225 and improving the ease of operation.

[0046] In this embodiment, the frame 25 is composed of four sets of hollow square tubes, forming an overall U-shaped structure. Adjacent hollow square tubes on the left, right, and rear sides are fixedly connected by crossbars. Connecting ear plate 251 is fixed to the inner surface of the four sets of hollow square tubes near the upper end. The connector 23 includes a right-angle clamping plate 231, a connecting ear plate 232, and a fastening bolt 233. The right-angle clamping plate 231 is fixed to the inner surface of the lower end of the hollow square tube on the frame 25. A connecting ear plate 232, perpendicular to the right-angle clamping plate 231, is fixed to the inner side of the right-angle clamping plate 231. The specifications of the connecting ear plate 232 are compatible with those of the connecting ear plate 251. A fastening bolt 233 is provided on the connecting ear plate 232, and a nut is fitted to the lower end of the fastening bolt 233. The right-angle clamping plate 231 is fixed to the inner surface of the lower end of the hollow square tube on the frame 25. Its right-angle structure allows for precise positioning and fit against the inner wall of the square tube, facilitating rapid connection and positioning between different unit cabinets 2. When assembling frame 25, align and fit connecting ear plate 1 232 and connecting ear plate 251 together. Fastening bolts 233 pass through the corresponding bolt holes on connecting ear plate 1 232 and connecting ear plate 251, and nuts are installed at the lower ends and tightened. Through the cooperation of the fastening bolts 233 and nuts, connecting ear plate 1 232 and connecting ear plate 251 are tightly connected together, thus achieving the splicing and fixing between unit cabinets 2.

[0047] In this embodiment, a top square tube 11 is fixedly installed on the inner side of the cabinet top cover 1 near the four corners, and the position of the top square tube 11 corresponds to the position of the square tube on the frame 25. A connector 23 is fixedly installed at the lower end of the top square tube 11.

[0048] In this embodiment, a bottom square tube 33 is fixed at each of the four corners of the upper surface of the base 3. The position of the bottom square tube 33 corresponds to the position of the square tube on the frame 25. A connecting ear plate 251 perpendicular to the upper end is fixed on the inner side of the bottom square tube 33. This design facilitates the quick splicing and fixing of the cabinet top cover 1, the unit cabinet 2 and the base 3.

[0049] In this embodiment, the base 3 has cable routing holes 31 inside for cable management. These holes provide dedicated channels for various cables such as power cables, data cables, and network cables of the equipment inside the cabinet. Through the cable routing holes 31, cables can be orderly led out from the bottom of the cabinet, avoiding messy cable distribution inside the cabinet and making the internal space of the cabinet neater. This facilitates subsequent cable maintenance and troubleshooting. Foot pads 32 are fixed at the four corners of the bottom of the base 3, providing stable support for the cabinet and allowing it to be placed stably on the ground. The foot pads 32 also separate the base 3 from the ground, preventing ground moisture from entering the cabinet and protecting the equipment from damage caused by a humid environment.

[0050] The working principle of this modular server rack for computer rooms:

[0051] In actual use, first place the base 3 on the ground, take a set of unit cabinets 2, place them on the base 3, and make the right-angle clip 231 at the bottom of the unit cabinet 2 attach to the bottom square tube 33 of the base 3. Then, fix the unit cabinet 2 with the fastening bolts 233 and nuts. Next, according to the above splicing method between unit cabinets 2, vertically splice other unit cabinets 2 on top of the installed unit cabinet 2. After splicing each unit cabinet 2, ensure that the connecting ear plate 1 232 and the connecting ear plate 251 are aligned and fitted, and tighten the fastening bolts 233 to ensure the stability of the splicing. Hoist the cabinet top cover 1 to the top of the uppermost unit cabinet 2, adjust the position of the cabinet top cover 1 so that the top square tube 11 on its inner side corresponds to the square tube on the frame 25 of the unit cabinet 2. Then, use the connecting piece 23 on the cabinet top cover 1 to cooperate with the connecting ear plate 251 at the upper end of the frame 25 of the unit cabinet 2, and use the fastening bolts 233 to fix the cabinet top cover 1 to the top of the unit cabinet 2. Based on the server's size and installation requirements, select the appropriate positioning hole 27, and fix the bent part of the side plate 221 of the bracket 22 to the positioning hole 27 of the frame 25 using fastening bolts 233, thus completing the installation of the bracket 22. Pull out the tray 225 using the telescopic slide rail 229, place the server on the tray 225, and easily move the server to the appropriate position using the rolling friction characteristics of the rollers 222. Organize and guide the server's power cord, data cable, network cable, and other cables through the cable tray 228 on the rear side of the bracket 222's base plate 223, and then lead them out through the cable routing hole 31 inside the base 3 to connect to the corresponding equipment in the computer room.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
