[0053] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present disclosure.

[0054] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below with reference to the drawings and specific embodiments.

[0055] Please refer to Fig. 1 and Fig. 2, Fig. 1 is a schematic view of a server cabinet provided by an embodiment of the present disclosure, and Fig. 2 is a schematic view of a second cabinet provided by an embodiment of the present disclosure.

[0056] As shown in Fig. 1 and Fig. 2, the server cabinet mainly comprises a first cabinet 1, a second cabinet 2 and an extension device 3. The first cabinet 1 has a cabinet space inside. The second cabinet 2 is installed in the cabinet space. The second cabinet 2 has a box space inside for installing a machine case 5. The front end and the rear end of the second cabinet 2 both have an extension site. The second cabinet 2 and the first cabinet 1 leave a communication space leading to the extension sites at both ends. The extension device 3 is installed in the extension site. One end of the extension device 3 is used to be connected with the machine case 5 through a connecting structure, and the connecting structure is located in the communication space. The other end of the extension device 3 is used to be connected with an external device.

[0057] It should be noted that the front end and the rear end of the second cabinet body 2 have expansion positions, and the expansion device 3 can be installed in the expansion positions, so that the expansion device 3 can be installed at the front end of the second cabinet body 2, or at the rear end of the second cabinet body 2, or at both the front end and the rear end of the second cabinet body 2. Here, it is defined that the installation position of the expansion device 3 on the second cabinet body 2 is flexible and variable.

[0058] In the existing server cabinet design, there are usually some limitations, such as various modules occupying valuable space inside the cabinet or being able to be placed only at the rear of the cabinet, which leads to insufficient space utilization, cumbersome and inefficient maintenance. In order to overcome these limitations, the technical solution proposes a highly flexible server cabinet design. The server cabinet design is composed of a first cabinet body 1 and a second cabinet body 2, the first cabinet body 1 has a cabinet space inside, and the second cabinet body 2 is installed in the cabinet space, and the inside is designed with a box space for installing a case 5. The innovation lies in that the front end and the rear end of the second cabinet body 2 have expansion positions, and there is a communication space between the second cabinet body 2 and the first cabinet body 1 leading to the expansion positions at both ends. Such a layout allows the expansion device 3 to be flexibly installed in the expansion positions, one end connected to the case 5 through the connecting structure located in the communication space, and the other end connected to the external equipment.

[0059] This design significantly improves the space utilization efficiency of the cabinet, because the expansion device 3 can be flexibly adjusted at the front and rear ends as needed, thereby reducing the problem of modules occupying internal space. At the same time, since the maintenance personnel can operate from the front or rear of the cabinet, both front maintenance and rear maintenance modes are realized, which greatly improves the convenience and efficiency of maintenance. In addition, the flexible installation of the expansion device 3 and the adjustability of the front and rear ends enable the cabinet to quickly expand functions according to actual needs, whether it is to increase cooling modules, network interfaces or other functional modules, it can be realized by simply installing or replacing the expansion device 3. This design significantly improves the multifunctionality and adaptability of the cabinet, enabling it to adapt to different data center layouts and operation and maintenance needs, while maintaining a high degree of customizability and expandability.

[0060] In combination with the above structure and process description, it can be seen that the server cabinet has at least the following beneficial effects: through the flexible adjustment of the expansion device 3 at the front and rear ends, the server cabinet realizes the selectable front maintenance and rear maintenance functions, thereby significantly improving the convenience and efficiency of maintenance, and expanding the multifunctionality and adaptability of the cabinet.

[0061] In particular, compared with the scheme in the prior art that places each module at the rear of the cabinet, the present disclosure installs the expansion device 3 at the front end of the second cabinet body 2.

[0062] In terms of individual modules, liquid cooling modules are key components for cooling servers, and they usually need to be placed close to the servers to ensure effective heat dissipation. However, due to design limitations, liquid cooling modules often occupy valuable space inside the cabinet, hindering the arrangement of other equipment. The same applies to power modules, which must be placed close to the server motherboard to provide stable power supply, limiting their installation location. Network interface modules, which are crucial for connecting network devices, are usually arranged at the back of the cabinet. Although this design facilitates connection and maintenance, it also occupies a large amount of rear space, resulting in insufficient utilization of the front space.

[0063] The limitations of placing individual modules at the back of the cabinet are particularly evident in wider cabinets. Even if there is enough space on both sides, it cannot be effectively utilized. The increase in width does not improve space utilization efficiency, but rather leaves the left and right spaces idle. Despite having enough space, the left and right spaces cannot be fully utilized due to installation limitations and layout design, resulting in resource waste.

[0064] In contrast, since there is enough space on both sides of the first cabinet 1, an extension device 3 that can be maintained at the front end can be added outside the second cabinet 2. This design not only optimizes the space utilization inside the cabinet but also improves the convenience of maintenance.

[0065] This layout allows maintenance personnel to maintain the extension device 3 at the front of the cabinet without the need for complex operations from the back of the cabinet. This greatly simplifies the maintenance process and improves work efficiency. The flexibility of front-end maintenance also allows the extension device 3 to be replaced with other functional devices, including but not limited to cooling, power management, network interface, etc., further enhancing the versatility and adaptability of the cabinet.

[0066] In addition, another significant advantage of this design is the modular layout and maintenance. Each front-maintained extension device 3 can be independently detached and replaced without the need to disassemble the entire cabinet or affect the normal operation of other modules. This modular design not only improves maintenance efficiency but also reduces downtime caused by replacing or maintaining a single module, thereby improving the overall reliability and efficiency of the data center.

[0067] In particular, the server cabinet provided by the present disclosure not only has front maintenance functions, but also can realize more flexible layout and management according to the placement and arrangement of the data center cabinet. Specifically, various extension devices 3 with different functions can be installed at the back end of the second cabinet 2 according to actual needs. In this way, the cables or liquid cooling pipes in front of the system can be connected to the extension devices 3 at the back, thereby realizing a rear outlet maintenance method.

[0068] For example, if the rear space of the cabinet is sufficient and maintenance is desired through the rear, an extension device 3 that can be maintained at the rear end can be added outside the second cabinet body 2. In this way, the maintenance personnel can directly perform cable management and liquid cooling pipe connection from the rear of the cabinet without needing to operate from the front of the cabinet, greatly simplifying the maintenance process.

[0069] In combination with the above two exemplary embodiments, it can be seen that the server cabinet provided by the present disclosure can be flexibly adjusted between front-end maintenance and rear-end maintenance according to the placement and arrangement of the data center cabinet. Whether front maintenance or rear maintenance, the most suitable way can be selected according to the actual situation, thereby improving the convenience and efficiency of maintenance.

[0070] In actual application, such a front-rear maintenance replaceable server cabinet provides great convenience for the management and maintenance of data centers. The operation and maintenance personnel can quickly access or remove various extension devices 3, thereby achieving efficient management and maintenance of the equipment inside the cabinet. Through reasonable space utilization and flexible module design, this innovative server cabinet greatly improves the operation and maintenance efficiency of the data center and the flexible configuration capability of the equipment, meeting the efficient, flexible and reliable operation and maintenance requirements of modern data centers.

[0071] Please continue to refer to FIG. 1 and FIG. 2, in some embodiments, the width of the second cabinet body 2 is less than the width of the first cabinet body 1, the second cabinet body 2 is movably installed in the front-rear direction relative to the first cabinet body 1, the extension sites are located at the two sides of the front end of the second cabinet body 2 and the two sides of the rear end of the second cabinet body 2, the extension device 3 is installed on the two sides of the second cabinet body 2 through the extension sites, and the connection structure connected with the extension device 3 is located on the side of the second cabinet body 2.

[0072] In the present example, the width of the second cabinet body 2 is less than the width of the first cabinet body 1, so that the second cabinet body 2 can be flexibly slid in the front-rear direction inside the first cabinet body 1, which significantly improves the space utilization efficiency of the cabinet and the convenience of maintenance.

[0073] The extension sites are specifically arranged on the sides of the front end and the rear end of the second cabinet body 2 to provide installation positions for the extension device 3. The extension device 3 is installed on the sides of the second cabinet body 2 through these extension sites, and at the same time, the connection structure connected with the extension device 3 is also located on the side of the second cabinet body 2. Such an arrangement optimizes the line management inside the cabinet, making the connection cables more tidy and facilitating the operation and inspection of the maintenance personnel. This design not only improves the functionality of the cabinet, but also enhances its ability to adapt to different data center layouts.

[0074] Please continue to refer to FIG. 1 and FIG. 2, in some embodiments, the cabinet space is divided into multiple cabinet regions in the height direction, and multiple second cabinets 2 are installed in the cabinet space and independently distributed in the cabinet regions; and / or, the box space is divided into multiple box regions in the height direction, and multiple machine boxes 5 are installed in the box space and independently distributed in the box regions.

[0075] In this example, the design of the cabinet space adopts a modularization in the height direction, which is divided into multiple cabinet regions, and each region can independently install a second cabinet 2. This design allows the server cabinet to maximize the utilization of space in the vertical direction, while providing flexibility to accommodate the installation needs of different numbers of second cabinets 2.

[0076] Similarly, the box space is also designed to be divisible in the height direction, forming multiple box regions, and each box region can install an independent machine box 5. This modular box design allows the server cabinet to flexibly adjust the distribution and number of machine boxes 5 according to specific equipment needs and space layout.

[0077] Through this partition design in the vertical direction, the server cabinet not only improves the space utilization, but also increases the adaptability and expandability of the cabinet. Whether it is to increase the second cabinet 2 or the machine box 5, it can be quickly adjusted according to actual needs, so as to meet the diversified needs of data center for server equipment management.

[0078] Please refer to FIG. 3 and FIG. 4, FIG. 3 is a schematic diagram of an expansion device provided by an embodiment of the present disclosure, and FIG. 4 is a schematic diagram of another expansion device provided by an embodiment of the present disclosure.

[0079] In some embodiments, the expansion device 3 includes:

[0080] The installation module 31 is installed in the expansion site, the installation module 31 is located on the side of the second cabinet 2, and the installation module 31 is provided with an installation surface;

[0081] The function module 32 is installed on the installation surface, the function module 32 is located on the side of the second cabinet 2, and the connection structure connected with the expansion device 3 is located on the side of the second cabinet 2.

[0082] In this example, the design of the expansion device 3 includes the installation module 31 and the function module 32, which together constitute the core part of the expansion device 3. The installation module 31 is directly installed in the expansion site, specifically, it is installed on the side of the second cabinet 2 and provides an installation surface for subsequent component installation. Such design allows the installation module 31 to provide necessary support and fixing points for the function module 32.

[0083] The functional module 32 is then mounted on the mounting surface provided by the mounting module 31, also located on the side of the second cabinet 2. The mounting position of the functional module 32 allows it to be connected to the connection structure of the expansion device 3, which is also located on the side of the second cabinet 2. This layout allows the functional module 32 to be effectively connected to the chassis 5 or other external equipment, while maintaining a neat appearance and easy-to-maintain design.

[0084] Through this design, the expansion device 3 not only provides an intuitive and convenient mounting method, but also, through the cooperation of the mounting module 31 and the functional module 32, enables the server cabinet to be quickly expanded in function as needed, such as adding cooling modules, network interfaces, or other specialized functional modules, thereby enhancing the versatility and adaptability of the cabinet.

[0085] It should be noted that the specific functions of the expansion device 3 and the specific form of the functional module 32 are not limited in this embodiment. As shown in FIG. 3, the functional module 32 can be a water distribution module 321, at which time the expansion device 3 has a cooling function, as shown in FIG. 4, the functional module 32 can be a network interface module 322, at which time the expansion device 3 has a network interface function. In addition to those shown in FIG. 3 and FIG. 4, other expansion devices 3 should also be within the scope of this disclosure.

[0086] As shown in FIG. 3, in some embodiments, the expansion device 3 includes a functional module for connecting the chassis 5 to external equipment, and the connection structure includes a water pipe assembly 331, and the functional module 32 includes:

[0087] The water distribution module 321 is used to connect to the chassis 5 through the water pipe assembly 331, and the water distribution module 321 is also used to connect to external equipment.

[0088] In this example, the design of the expansion device 3 places particular emphasis on its connection function, particularly through the water pipe assembly 331 to achieve the connection between the chassis 5 and external equipment. This design allows the equipment inside the cabinet to be effectively connected to external cooling systems or other hydraulic facilities.

[0089] The functional module 32 plays a key role in this process, and it includes the water distribution module 321. The water distribution module 321 is specifically designed to connect to the chassis 5 through the water pipe assembly 331, ensuring that the cooling liquid or water can be effectively distributed into the chassis 5 to maintain the server equipment operating at an appropriate temperature. In addition, the water distribution module 321 can also be connected to external equipment, which allows the cabinet to easily access a wider range of cooling solutions or hydraulic management systems.

[0090] With this design, the server cabinet not only improves the heat dissipation efficiency, but also increases the compatibility and flexibility of connection with external cooling systems. This provides a high-efficiency and customizable cooling solution for data centers, which helps to improve the operation efficiency and reliability of the entire data center.

[0091] Please refer to Figure 5, which is a schematic diagram of the extension device and the second cabinet body in Figure 3.

[0092] In some embodiments, the water distribution module 321 is vertically arranged, and the rear end of the water distribution module 321 is equipped with multiple groups of vertically distributed pipe port assemblies. Each group of pipe port assemblies is used to correspondingly connect with the chassis 5 in the cabinet space through the water pipe assembly 331, and the height of each group of pipe port assemblies is used to correspondingly set with the height of the chassis 5 in the cabinet space.

[0093] In this example, the design of the water distribution module 321 adopts a vertical layout, which makes the module more efficient in connecting with the chassis 5 and adapts to different heights of the chassis. The rear end of the water distribution module 321 is equipped with multiple groups of pipe port assemblies, which are vertically distributed to facilitate connection.

[0094] Each group of pipe port assemblies is designed with a specific height to connect with the corresponding height of the chassis 5 in the cabinet space through the water pipe assembly 331. Such corresponding setting ensures that no matter which height level the chassis 5 is in the cabinet space, the water distribution module 321 can accurately connect with them to achieve the distribution of cooling liquid.

[0095] Through this vertical arrangement and corresponding height design, the water distribution module 321 not only improves the accuracy and convenience of connection, but also enhances the efficiency and adaptability of the entire server cabinet in terms of heat dissipation and cooling. This design allows the cabinet to flexibly install different specifications of chassis at different heights, while ensuring the efficient operation of the cooling system.

[0096] Each group of water pipe assemblies 331 includes a cold water branch pipe and a hot water branch pipe, and multiple cold water branch pipes and multiple hot water branch pipes of multiple water pipe assemblies 331 are connected to the water distribution module 321. After the cold water of the multiple cold water branch pipes and the hot water of the multiple hot water branch pipes are respectively collected by the water distribution module 321, they are connected to external equipment through the cold water main pipe and the hot water main pipe.

[0097] As shown in Figure 4, in some embodiments, the extension device 3 includes a functional module for connecting the chassis 5 with external equipment, and the connection structure includes a cable assembly 332. The functional module 32 includes:

[0098] The network port module 322 is used to connect with the chassis 5 through the cable assembly 332, and is also used to connect with external equipment.

[0099] In this example, the design of the extension device 3 focuses on the flexibility and practicality of electrical connections, especially the connection between the cabinet 5 and external devices through the cable assembly 332. This design allows the server devices inside the cabinet to be effectively connected to external networks or other electronic devices.

[0100] The network port module 322 included in the function module 32 plays a key role in achieving such connections. The network port module 322 is specifically designed to connect with the cabinet 5 through the cable assembly 332, ensuring that network data can be efficiently transmitted to the server devices. In addition, the network port module 322 can also be connected with external devices, providing the cabinet with the ability to connect with a wider network environment or external systems.

[0101] Through this design, the server cabinet not only enhances the flexibility of network connections, but also improves the convenience of integration with external devices. This provides strong support for building efficient and reliable network infrastructure in data centers, helping to improve the operating efficiency and data processing capacity of the entire data center.

[0102] Please refer to Figure 6, which is a schematic diagram of the extension device and the second cabinet body in Figure 4.

[0103] In some embodiments, the network port module 322 is vertically arranged, and the rear end of the network port module 322 is provided with multiple groups of vertically distributed line port assemblies, each group of line port assemblies being used to correspondingly connect with the cabinet 5 in the cabinet space through the cable assembly 332, and the height of each group of line port assemblies being used to correspondingly set with the height of the cabinet 5 in the cabinet space.

[0104] In this example, the design of the network port module 322 adopts a vertical layout, which enables the module to effectively connect with cabinet 5 of different height levels. The rear end of the network port module 322 is equipped with multiple groups of line port assemblies, which are distributed vertically to provide cabinet 5 with convenient network connection points.

[0105] Each group of line port assemblies is arranged at a specific height to connect with the cabinet 5 at the corresponding height in the cabinet space through the cable assembly 332. This corresponding height arrangement ensures that the cabinet 5 can be conveniently connected to the network regardless of its vertical position in the cabinet. Such design not only improves the accuracy and convenience of connection, but also makes the network wiring of the cabinet more neat and orderly.

[0106] Through this vertical arrangement and height corresponding design, the network port module 322 significantly improves the flexibility and adaptability of the server cabinet in network connection, ensuring that the server devices can efficiently access the network system of the data center. This provides strong support for network management and optimization of the data center, helping to improve the network performance and operating efficiency of the data center.

[0107] Please continue to refer to Figure 1 and refer to Figure 7, which is a schematic diagram of the server cabinet provided by the embodiments of the present disclosure.

[0108] In some embodiments, the width of the first cabinet 1 is greater than the width of the second cabinet 2, and the width of the second cabinet 2 is greater than the width of the chassis 5. The second cabinet 2 is slidingly installed relative to the first cabinet 1 in the front-back direction, and the second cabinet 2 is used to achieve sliding installation of the chassis 5 relative to the second cabinet 2 in the front-back direction.

[0109] In this example, the width of the first cabinet 1 is designed to be larger than the width of the second cabinet 2, which is done to leave enough space for the second cabinet 2 to slide freely inside the first cabinet 1. Accordingly, the width of the second cabinet 2 is also greater than the width of the chassis 5, ensuring that the chassis 5 can also be slidingly installed inside the second cabinet 2.

[0110] The sliding installation design of the second cabinet 2 allows it to move in the front-back direction of the first cabinet 1, which provides flexibility during installation and maintenance. Similarly, the chassis 5 is also designed to slide in the front-back direction inside the second cabinet 2, which further enhances the convenience of maintenance of the cabinet and the accessibility of the chassis.

[0111] Through this design, the server cabinet not only improves the space utilization efficiency, but also allows more flexible equipment installation and replacement process. When the chassis 5 needs to be maintained or upgraded, the second cabinet 2 and the chassis 5 inside it can be easily slid out together, so that the required operation can be quickly performed. This design significantly improves the operation and maintenance efficiency of the data center, and also makes the cabinet layout more compact and efficient.

[0112] Please continue to refer to Figure 1 and Figure 7, on the one hand, the server cabinet provided by the present disclosure greatly simplifies the removal and maintenance process of the chassis 5. Specifically, when a chassis 5 needs to be removed, first, only need to move the second cabinet 2 outward, so that it is separated from the fixed position. Then, pull out the water pipe assembly 331 behind the water distribution module 321, and the chassis 5 can be easily removed. This design significantly reduces the time and complexity of removing and maintaining the chassis 5.

[0113] The core of this design is the replaceability of front and back maintenance, which means that users can perform maintenance operations from the front or back of the cabinet without the need to disassemble the entire cabinet. This flexibility not only improves maintenance efficiency, but also reduces interference with the operation of other equipment. In traditional designs, removing a chassis may require disassembling multiple components, or even affecting the normal operation of other equipment, while this new design avoids these problems.

[0114] On the other hand, the design of the water diversion and mold module 321 also embodies the concept of efficient management and maintenance. By setting the water pipe interface at the back of the module, the operator can quickly connect and disconnect, ensuring the stable operation of the cooling system. This is particularly important for data centers that require frequent maintenance and replacement of equipment. The simple operation of pulling out the water pipe interface makes it possible to quickly remove and replace the chassis 5 without affecting the operation of other equipment.

[0115] This front and rear maintenance replaceable design not only applies to the chassis 5, but also can be extended to other types of modular components. Through reasonable design and layout, various functional modules can be replaced flexibly as needed, further enhancing the adaptability and versatility of the cabinet. Whether it is a power module, a network interface module such as a network port module 322, or other special modules, they can be quickly maintained and replaced in this way, greatly improving the management efficiency and operational flexibility of the data center.

[0116] In another aspect, the design of the network port module 322 also embodies the concept of efficient management and maintenance. When it is necessary to remove a certain chassis 5, the user only needs to move the second cabinet body 2 outward to disengage it from the fixed position. Then, by pulling out the cable assembly 332 located at the back of the network port module 322, the chassis 5 can be easily removed. This design avoids the complex process of removing multiple components when removing the chassis in the traditional way, thereby significantly improving the efficiency of removal and maintenance.

[0117] Through this design, the server cabinet also achieves the purpose of quickly maintaining and replacing the chassis 5, while reducing the potential interference to other equipment in the data center, optimizing the entire maintenance process.

[0118] Please refer to FIGS. 8-10, FIG. 8 is an exploded view of the expansion device according to an embodiment of the present disclosure, FIG. 9 is a schematic view of the expansion device and the second cabinet body according to an embodiment of the present disclosure, and FIG. 10 is a schematic view of the expansion device and the second cabinet body according to an embodiment of the present disclosure.

[0119] In some embodiments, the expansion device 3 includes functional modules for connecting the chassis 5 with external equipment and mounting modules 31 for mounting the functional modules 32 to the second cabinet body 2, and the mounting modules 31 include:

[0120] The side hanging rack 311 is connected to the functional module 32, and the side hanging rack 311 is provided with a mounting slot 3111;

[0121] The second cabinet body 2 is provided with a T-shaped nail 21 and a fixing hole, the T-shaped nail 21 is used for sliding assembly with the mounting slot 3111, and the fixing hole is used for fixing the side hanging rack 311 on the second cabinet body 2 by cooperating with a hand screw after the side hanging rack 311 is assembled in place.

[0122] In this example, the design of the expansion device 3 pays special attention to the convenience and flexibility of installation. The expansion device 3 not only contains a functional module 32 for realizing the connection of the chassis 5 with external devices, but also contains a mounting module 31 specially designed to facilitate the installation of the functional module 32 on the second cabinet body 2.

[0123] The core component of the mounting module 31 is the side-hanging rack 311, which is directly connected to the functional module 32. The side-hanging rack 311 is designed with a mounting slot 3111, which is a key part for matching with the structure on the second cabinet body 2. The second cabinet body 2 is specially designed with T-shaped nails 21 and fixing holes to adapt to the side-hanging rack 311. The T-shaped nails 21 can be slidably assembled with the mounting slot 3111, which allows the side-hanging rack 311 to be easily positioned and fixed on the side of the second cabinet body 2.

[0124] Once the side-hanging rack 311 is assembled in place, the fixing holes and hand screws (such as the first hand screw 341 shown in the figure) can be used to achieve stable fixation of the side-hanging rack 311 on the second cabinet body 2. This design not only simplifies the installation process, but also improves the stability and reliability of the entire expansion device 3.

[0125] Through this design, the expansion device 3 can be flexibly installed on the side of the second cabinet body 2, providing more expansion possibilities for the server cabinet, and also facilitating the later maintenance and upgrade work. This innovative installation method improves the adaptability and functionality of the server cabinet, meeting the needs of modern data centers for high efficiency and flexibility.

[0126] In some embodiments, the functional module 32 is divided into a water distribution module 321 and a network port module 322, which are installed on the second cabinet body 2 through the side-hanging rack 311.

[0127] In this example, both the water distribution module 321 and the network port module 322 can be used with the side-hanging rack 311 and installed through a simple fixing method. This design optimizes the installation process and improves maintenance efficiency. The side-hanging rack 311 is fixed with the water distribution module 321 or the network port module 322 using screws, and then the functional module 32 is fixed to the second cabinet body 2 through the relationship between the T-shaped nails 21 and the fixing holes on the second cabinet body 2 and the hand screws. This design allows maintenance personnel to easily perform front and rear maintenance and replacement of the modules.

[0128] In some embodiments, the second cabinet body 2 has T-shaped nails 21 and fixing holes on both sides, and the same side-hanging rack 311 can be installed between the two sides of the second cabinet body 2, or two side-hanging racks 311 can be installed between the two sides of the second cabinet body 2.

[0129] In this example, the design of the second cabinet body 2 allows greater flexibility and adaptability, as both sides are equipped with T-shaped nails 21 and fixing holes. Such design features allow the same side-hanging rack 311 to be installed as needed between the two sides of the second cabinet body 2. In addition, if two side-hanging racks 311 are included in the design, they can also be installed interchangeably between the two side positions of the second cabinet body 2.

[0130] This design provides multiple layout options, making it easy to adjust the layout of components inside the server cabinet according to specific data center layout or maintenance needs. Whether it is necessary to expand the installation position of functional modules or to reconfigure to adapt to different equipment or connection needs, this interchangeable installation design greatly improves the practicality and flexibility of the server cabinet. In this way, the second cabinet body 2 can make more efficient use of space while providing greater convenience for maintenance personnel to adapt to various maintenance scenarios.

[0131] Please continue to refer to Figure 2 and refer to Figure 11, which is a schematic diagram of the collection and arrangement device provided by the embodiment of the present disclosure.

[0132] In some embodiments, the server cabinet further comprises:

[0133] The collection and arrangement device 4 is installed on the second cabinet body 2, and the collection and arrangement device 4 is located in the communication space. The collection and arrangement device 4 is used to store and arrange the connection structure.

[0134] In this example, the design of the server cabinet further includes the collection and arrangement device 4, which is installed on the second cabinet body 2 and located in the communication space. The main function of the collection and arrangement device 4 is to store and arrange the connection structure inside the cabinet, such as cable components 332 and water pipe components 331. In this way, the collection and arrangement device 4 helps to keep the inside of the cabinet clean and orderly, and also facilitates the management and inspection of the connection structure by maintenance personnel.

[0135] In addition, the design of the collection and arrangement device 4 also takes into account the efficient use of internal space of the cabinet, ensuring the reasonable layout of the connection structure, avoiding the disorder of cables and pipes, and reducing the risk of interference and damage that may occur during maintenance and upgrading. This design not only improves the aesthetics of the cabinet, but also improves the maintenance efficiency and reliability of the server cabinet. Through the integration of the collection and arrangement device 4, the internal management and maintenance work of the server cabinet becomes more efficient and orderly.

[0136] Please continue to refer to Figures 5 and 6. In some embodiments, the collection and arrangement device 4 is located on the side of the second cabinet body 2, and the number of collection and arrangement devices 4 is multiple. Multiple collection and arrangement devices 4 are distributed in the length direction of the server cabinet and / or multiple collection and arrangement devices 4 are distributed in the height direction of the server cabinet.

[0137] In this example, the collection device 4 is specially designed to be located on the side of the second cabinet body 2. Such a layout allows the collection device 4 to be closer to the connection structure inside the cabinet, facilitating management and arrangement. Moreover, the collection device 4 is not single, but multiple, which is distributed in the length direction of the server cabinet and also in the height direction of the server cabinet.

[0138] Such a layout improves the use efficiency of the collection device 4, ensures that the lines and pipes inside the cabinet can be neatly managed and maintained, thereby improving the cleanliness and convenience of the entire server cabinet.

[0139] In addition, this design also allows flexible adjustment of the position and number of the collection device 4 according to the specific cabinet layout and equipment installation needs, to adapt to different operation and maintenance scenarios and specific needs of the data center. Such flexibility and scalability is an important feature of the server cabinet design in this embodiment.

[0140] In some embodiments, the collection device 4 includes:

[0141] The base 41 is mounted on the second cabinet body 2, and the base 41 is provided with a hinge seat 411 and a locking hole;

[0142] The rotating plate 42 is rotatably installed in the hinge seat 411, and when the rotating plate 42 is rotated to a closed angle, a circumferentially closed and axially through accommodating channel is formed between the rotating plate 42 and the base 41. The rotating plate 42 is fixed on the base 41 by cooperating with the locking hole through a hand screw.

[0143] In this example, the design details of the collection device 4 are further explained, which consists of several key parts to achieve its function. First, the base 41 is mounted on the second cabinet body 2, and the base 41 is not only provided with a stable support, but also provided with a hinge seat 411 and a locking hole. These features enable the base 41 to work in coordination with other parts of the collection device 4.

[0144] The rotating plate 42 is designed to be rotatably installed in the hinge seat 411. This design allows the rotating plate 42 to be opened or closed when needed, providing convenient access and arrangement space. When the rotating plate 42 is rotated to a closed position, a circumferentially closed and axially through accommodating channel is formed between the rotating plate 42 and the base 41. This channel is specially designed to accommodate and arrange connection structures such as cable assembly 332 and water pipe assembly 331.

[0145] The rotating plate 42 is fixed on the base 41 by cooperating with the locking hole through a hand screw (such as the second hand screw 43 shown in the figure). This fixing method not only ensures the stability of the rotating plate 42, but also allows maintenance personnel to easily open or close the rotating plate 42 when needed to maintain or arrange the connection structure.

[0146] Through this design, the collecting and organizing device 4 not only improves the tidiness and organization of the inside of the cabinet, but also increases the protection of the connecting structure and reduces the risk of damage that may occur during maintenance and upgrading, thereby improving the reliability and operation efficiency of the entire server cabinet.

[0147] In the present disclosure, the side distribution scheme of the connecting structure and the collecting and organizing device 4 also solves the interference problem. Specifically, by using a hand screw to fix the base 41 of the collecting and organizing device 4, this design can effectively prevent the connecting structure from interfering with the first cabinet 1 when the second cabinet 2 is pushed into the first cabinet 1. This strategy not only takes into account the limited space inside the cabinet, but also takes into account the necessity of pipe and cable management.

[0148] In addition, using a hand screw (such as the first hand screw 341 or the second hand screw 43) to fix the expansion device 3 and the collecting and organizing device 4 simplifies the installation and maintenance process. Compared with the traditional screw fixing method, the advantage of the hand screw is that it does not need to use power tools or other equipment, and maintenance personnel can complete the installation by manually rotating, which significantly improves the flexibility and convenience of operation. This design reflects the emphasis on operation efficiency and maintenance convenience, and conforms to the pursuit of high efficiency and high adaptability of modern data centers.

[0149] In some embodiments, the first cabinet 1 includes a first top cover, a first bottom plate, and a first side plate, the first top cover and the first bottom plate are spaced apart in the height direction, the top end of the first side plate is connected to the first top cover, and the bottom end of the first side plate is connected to the first bottom plate. The inside of the first top cover, the first bottom plate, and the first side plate forms a cabinet space; the inner side of the first side plate is provided with a plurality of groups of slide rail devices, and the plurality of groups of slide rail devices are distributed along the height direction.

[0150] The second cabinet 2 includes a second top cover, a second bottom plate, and a second side plate, the second top cover and the second bottom plate are spaced apart in the height direction, the top end of the second side plate is connected to the second top cover, and the bottom end of the second side plate is connected to the second bottom plate. The inside of the second top cover, the second bottom plate, and the second side plate forms a cabinet space; the outer side of the second side plate is provided with a slide rail piece that slidably cooperates with the slide rail device, and the second cabinet 2 can be pulled and slid in the front-back direction relative to the first cabinet 1. The second cabinet 2 corresponds to the slide rail device one by one, and a plurality of second cabinets 2 are distributed in the height direction; the second cabinet 2 is used to realize the stacking installation of the machine case 5 in the cabinet space, and the machine case 5 can be pulled and slid in the front-back direction relative to the second cabinet 2.

[0151] Please refer to FIG. 12, which is a schematic view of a second cabinet provided by another embodiment of the present disclosure.

[0152] As shown in FIG. 12, the expansion device 3 and the storage device 4 are provided in a set and arranged in groups in the height direction. The outer side of the second side plate is provided with the first expansion device 3 and a plurality of storage devices 4 for storing and arranging the connection structure connected to the first expansion device 3 in the length direction of the first height. The outer side of the second side plate is provided with the second expansion device 3 and a plurality of storage devices 4 for storing and arranging the connection structure connected to the second expansion device 3 in the length direction of the second height.

[0153] In the present example, the design of the expansion device 3 and the storage device 4 takes into account the space utilization and maintenance convenience of the server cabinet in the height direction. The expansion device 3 and the storage device 4 are provided in a set, which means they are designed and arranged to jointly complete a specific function.

[0154] Specifically, the second side plate of the second cabinet body 2 is provided with the expansion device 3 at two different heights. At the first height, the outer side of the second side plate is mounted with the first expansion device 3, which is matched with a plurality of storage devices 4 specially used for storing and arranging the connection structure connected to the first expansion device 3. Such design enables effective management and maintenance of the connection structure at the first height, ensuring the neatness and orderliness of the cabinet interior. As an option, the first expansion device 3 includes a water distribution module 321, and the connection structure is a water pipe assembly 331.

[0155] Similarly, at the second height, the outer side of the second side plate is mounted with the second expansion device 3, which is also matched with a plurality of storage devices 4 responsible for storing and arranging the connection structure connected to the second expansion device 3. As an option, the second expansion device 3 includes a network port module 322, and the connection structure is a cable assembly 332.

[0156] Through this design, the server cabinet can better adapt to the equipment installation requirements at different heights, realizing the flexibility and personalized customization of functional support, while ensuring the orderliness and maintainability of the connection structure. This grouping arrangement in the height direction improves the flexibility and expandability of the cabinet, making it serve a more complex and diverse data center environment.

[0157] In the present disclosure, the design of the server cabinet allows flexible selection and installation of functional modules according to the specific needs of the cabinet 5. For example, for a cabinet 5 that needs to enhance the heat dissipation function, the water distribution module 321 can be selected for installation to better manage the distribution of cooling liquid. For a cabinet 5 that needs to strengthen the network management function, the network port module 322 can be selected for installation to optimize network connection.

[0158] One of the significant advantages of this design is its personalization and flexibility. Users can freely choose and combine different functional modules according to their actual needs and the specific functional requirements of the equipment inside the cabinet. This flexibility breaks the limitations of traditional cabinet single-function layout, making the cabinet adapt to diverse application scenarios and personalized needs, providing users with more abundant and flexible choices. In this way, the design of the server cabinet meets the pursuit of modern data centers for high efficiency, high adaptability, and user customization.

[0159] In some embodiments, the first cabinet 1 is a 21-inch cabinet, the second cabinet 2 is a 19-inch cabinet, and the machine case 5 is a 19-inch machine case.

[0160] In this example, the server cabinet includes a first cabinet 1 with a size of 21-inch cabinet as the external frame, a second cabinet 2 with a size of 19-inch cabinet as the internal frame, and a machine case 5 with a size of 19-inch machine case as the internal machine case.

[0161] The design of the server cabinet follows the standard sizes in the industry to ensure compatibility and practicality. Specifically, the first cabinet 1 is defined as a 21-inch cabinet, which provides sufficient external space for the entire server cabinet to accommodate multiple second cabinets 2 and other necessary components.

[0162] The second cabinet 2 is a 19-inch cabinet, which is a common standard size in data centers and is suitable for installing various server equipment. Since the second cabinet 2 is designed to be installed inside the first cabinet 1, their sizes are matched to ensure efficient use of space. In addition, the machine case 5 is also 19 inches, which means they can be directly installed in the second cabinet 2, maintaining the standardization and modularity of the equipment, facilitating installation, maintenance, and upgrading.

[0163] By adopting these standardized sizes, the design of the server cabinet not only improves the efficiency of space utilization, but also ensures compatibility with existing equipment, while also facilitating future expansion and upgrading. This design meets the needs of data centers for flexibility and scalability, while also providing users with a convenient equipment integration solution.

[0164] In particular, the server cabinet also includes a security control system.

[0165] In this disclosure, the design of the server cabinet places particular emphasis on the construction of the security control system, particularly in terms of temperature monitoring, to ensure the stability and safety of the data center. The system consists of three key temperature sensors, an integrated controller, a multifunctional alarm, and an intuitive user interface and remote notification mechanism.

[0166] The core of the system is the three temperature sensors, each responsible for monitoring the temperature of different areas.

The second temperature sensor is located in the network port module 322, monitoring the cable temperature to prevent network failures caused by overheating. The newly added third temperature sensor is installed inside the second cabinet 2, next to the chassis 5, and monitors the temperature of the server components in real time, providing critical operating status data for the system.

[0167] The controller serves as the central hub of the system, receiving temperature signals from all sensors and comparing them with pre-set safety temperature intervals. If any abnormalities are detected, the controller will immediately activate the alarm. The alarm is designed for quick response in emergency situations, not only sounding an audible alarm, but also providing visual warnings through different colored and patterned light flashes, allowing operations personnel to quickly identify the problem type and take appropriate measures.

[0168] The user interface is designed to provide a clear display of real-time temperature data and system status, allowing operations personnel to monitor the heat management status of the cabinet at any time. In addition, the system's remote notification function can notify operations personnel in a timely manner through email, SMS or mobile application when abnormalities are detected, ensuring that even in remote situations, a quick response can be made.

[0169] The security control system is designed in strict accordance with the safety standards of data centers, including data encryption and access control, to ensure the security and integrity of monitoring data. The design of this system not only improves the temperature monitoring capability of the server cabinet, but also significantly enhances the prevention and response capability of the data center to potential overheating problems, ensuring the stable operation of the data center and the safety of the equipment.
