Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding technology, specifically to a shielded computer room that is suitable for complex magnetic field interference environments, can optimize cable layout and improve overall shielding effectiveness. Background Technology

[0002] To achieve shielding against complex external electromagnetic environments, existing shielded computer rooms typically employ a hexagonal metal plate welded or assembled structure. Various devices within the room (such as servers, switches, and testing instruments) require the introduction of multiple types of cables, including high-voltage power lines, low-voltage control lines, and high-frequency signal lines. These cables are usually introduced directly through perforations in the exterior walls of the computer room. Excessive wall penetrations compromise the integrity of the shielding structure. Even with waveguides, the concentrated introduction of a large number of cables is difficult to manage, becoming weak points for electromagnetic leakage. The mixed routing of cables of different properties within the computer room causes common-mode interference as the magnetic field generated by power lines is induced on signal lines, affecting the normal operation of the equipment. Furthermore, the haphazard cable routing makes troubleshooting extremely inconvenient when adding, removing, or replacing equipment, and each modification may affect the shielding performance. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems by providing a shielded computer room. Through a unique sandwich structure design, all cables complete initial connection, transfer, and distribution within the sandwich layer, achieving centralized, classified, and shielded management of cables. This fundamentally optimizes cable routing, reduces internal and external electromagnetic interference, and facilitates maintenance and expansion.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A shielded computer room includes a computer room body made of shielding panels. One or more side walls of the computer room body are provided with shielding shells that are physically connected to them. A shielding interlayer is formed between the shielding shells and the computer room body. The computer room body is also provided with a centralized inlet module that communicates with the shielding interlayer. The centralized inlet module is provided with several interfaces.

[0006] By adopting the above technical solution, and by setting up a shielding shell and shielding interlayer, and connecting it with a centralized entry module, the centralized entry of cables is realized, avoiding the destruction of shielding integrity by multiple wall penetrations and improving the electromagnetic shielding effect. At the same time, the multiple interfaces on the centralized entry module facilitate the access of different types of cables, reduce interference caused by cable mixing, reduce electromagnetic leakage points by using centralized management, and enhance the overall shielding performance.

[0007] Furthermore, the shielding interlayer is detachably connected to the main body of the computer room.

[0008] Thanks to the above technical solution, flexible adjustments are achieved through a detachable structure, reducing maintenance difficulties caused by fixed connections, and supporting rapid assembly and modification in terms of usage.

[0009] Furthermore, the shielding interlayer is provided with several metal partitions, which divide the shielding interlayer into multiple independent distribution channels.

[0010] Thanks to the above technical solution, the metal partitions inside the shielding interlayer divide the shielding interlayer into multiple independent distribution channels, allowing cables of different properties, such as power lines and signal lines, to be laid out separately. This avoids common-mode interference of the power line magnetic field on the signal lines and improves the stability of equipment operation. At the same time, the channelized layout makes the cables orderly, which is convenient for inspection and replacement, and improves the organization and anti-interference capability of the shielding interlayer.

[0011] Furthermore, one end of the metal partition is a connection end connected to the computer room body / shielding shell, and the other end is an assembly end. The shielding shell / computer room body is provided with an assembly slot that matches the assembly end.

[0012] Thanks to the above technical solutions, the design of the assembly slots makes the installation of metal partitions more convenient and secure. The slot structure enables rapid assembly and reliable contact, reduces installation errors and shielding gaps, and ensures electrical continuity between the metal partitions and the shielding housing or the main body of the computer room, thereby maintaining the overall shielding performance.

[0013] Furthermore, the assembly slot is provided with a flexible conductive layer.

[0014] Thanks to the above technical solution, the flexible conductive layer inside the assembly slot can fill the gap between the assembly end and the assembly slot, providing better electrical contact, improving the reliability and stability of the connection, reducing electromagnetic leakage, and ensuring a long-term stable shielding effect.

[0015] Furthermore, a distribution channel is formed between the metal partitions, the distribution channel including a distribution crossbeam and a distribution longitudinal beam, the distribution crossbeam and the distribution longitudinal beam being able to connect to form a cross-shaped distribution port.

[0016] Thanks to the above technical solution, the distribution channels formed between the metal partitions include distribution cross channels and distribution longitudinal channels, which can be connected to form a cross-shaped distribution port. This allows cables to be flexibly crossed and distributed within the shielding interlayer, adapting to the cable connection needs of different devices, reducing cable bending and tangling, facilitating wiring and maintenance, improving the efficiency of cable management and the space utilization of the shielding interlayer.

[0017] Furthermore, the interface includes at least one of a power filter interface, a signal filter interface, and an optical fiber waveguide interface.

[0018] Thanks to the above technical solutions, the system supports the safe access of various cables and can provide corresponding filtering and shielding for different cable types. The power filter interface can suppress electromagnetic interference from power lines, the signal filter interface protects signal lines from interference, and the fiber optic waveguide interface allows optical signals to be introduced without electromagnetic leakage. This comprehensively improves the anti-interference capability of the shielded room and solves the electromagnetic compatibility problem caused by cable introduction.

[0019] Furthermore, the walls of the shielding interlayer are coated with a paramagnetic material coating.

[0020] Thanks to the above technical solution, the paramagnetic material coating on the shielding interlayer wall can effectively absorb and attenuate low-frequency magnetic fields, making up for the shortcomings of insufficient magnetic field shielding by metal shielding bodies and improving the shielding effect against broadband electromagnetic interference.

[0021] Furthermore, the computer room body is also equipped with an equipotential grounding bus module. The shielding interlayer is connected to the equipotential grounding bus module, and the equipotential grounding bus module is electrically connected to the computer room body and the earth grounding electrode through a grounding conductor.

[0022] Thanks to the above technical solution, the equipotential grounding busbar module creates an equipotential connection between the shielding interlayer, the main body of the equipment room, and the grounding electrode, eliminating potential differences between the parts, preventing ground loop interference, and providing a discharge path for lightning strikes or surge currents, thus enhancing the safety and stability of the shielded equipment room.

[0023] Furthermore, the computer room body is equipped with an environmental monitoring module, which is connected to the alarm device.

[0024] Thanks to the above technical solutions, the environmental monitoring module installed outside the computer room can monitor environmental parameters around the computer room in real time, such as electromagnetic interference levels, temperature, and humidity. By connecting with the alarm device, it can promptly issue an alarm when abnormal situations occur, facilitating maintenance personnel to take countermeasures and ensuring the reliable operation of the shielded computer room.

[0025] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows: By setting up a shielding shell and a shielding interlayer, and connecting them with a centralized cable entry module, centralized cable entry and management are achieved, avoiding the damage to shielding integrity caused by multiple wall penetrations and improving the electromagnetic shielding effect; the multiple interfaces on the centralized entry module facilitate the access of different types of cables, reducing interference; the metal partitions set inside the shielding interlayer divide the shielding interlayer into independent channels, allowing power lines and signal lines to be laid out separately, avoiding common-mode interference and improving the stability of equipment operation; the metal partitions achieve reliable connection through mounting slots and flexible conductive layers, reducing electromagnetic leakage; the distribution channels facilitate flexible cable allocation; the paramagnetic material coating absorbs low-frequency magnetic fields; the equipotential grounding busbar module eliminates potential differences and prevents ground loop interference; the environmental monitoring module monitors environmental parameters from the outside in real time and provides timely alarms, thereby comprehensively improving the performance, safety, and reliability of the shielded equipment room.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1

[0034] A type of shielded computer room, such as Figures 1-4 As shown, the main body 10 of the computer room, consisting of shielding panels, is shown below. For clarity of the structure, [details omitted]. Figure 2 and Figure 3The image only shows one shielding plate within the main body 10 of the computer room. One or more side walls of the main body 10 have shielding housings 11 physically connected to them. The specific configuration can be customized as needed and is not constrained here. A shielding interlayer 12 is formed between the shielding housing 11 and the main body 10. The main body 10 also has a centralized cable entry module 13 connected to the shielding interlayer 12. The centralized entry module 13 has four interfaces 131. Specifically, by setting up the shielding housing 11 and shielding interlayer 12 and connecting them to the centralized entry module 13, centralized cable entry is achieved, avoiding the disruption of shielding integrity caused by multiple wall penetrations and improving electromagnetic shielding effectiveness. Simultaneously, the multiple interfaces 131 on the centralized entry module 13 facilitate the access of different types of cables, reducing interference caused by cable clutter. Centralized management reduces electromagnetic leakage points and enhances overall shielding performance. Understandably, the cable enters the shielding interlayer 12 through the interface 131 of the centralized entry module 13, is then laid out within the shielding interlayer 12, and finally connects to the internal equipment in the computer room body 10. This avoids creating multiple holes in the computer room body 10 and maintains the shielding integrity. In other embodiments, the centralized entry module 13 can be located at different positions in the computer room body 10, such as the top or bottom, to accommodate different cable entry requirements, or the number and type of the interfaces 131 can be adjusted according to the actual application.

[0035] The shielding interlayer 12 is detachably connected to the main body 10 of the computer room. Specifically, the detachable structure allows for flexible adjustment, reducing maintenance difficulties caused by fixed connections and supporting rapid assembly and modification. It is understood that the detachable connection can be achieved through bolts, clips, or plug-in methods, allowing for easy disassembly and reinstallation of the shielding interlayer 12 without affecting the structure of the main body 10 of the computer room when maintenance or modification is required. In other embodiments, the detachable connection can employ different fasteners or connection mechanisms, such as quick-release clips, to further improve assembly efficiency.

[0036] The shielding interlayer 12 is internally provided with several metal partitions 121, which divide the shielding interlayer 12 into multiple independent distribution channels 122. Each distribution channel 122 may be equipped with a locking mechanism, such as a spring clip, to facilitate cable positioning and installation. Specifically, the metal partitions 121 inside the shielding interlayer 12 divide it into multiple independent distribution channels 122, allowing cables of different properties, such as power lines and signal lines, to be laid out separately. This avoids common-mode interference from the magnetic field of the power line on the signal line, improving the stability of equipment operation. Simultaneously, the channelized layout keeps the cables orderly, facilitating inspection and replacement, and enhancing the organization and anti-interference capability of the shielding interlayer 12. It is understood that the metal partitions 121 are made of conductive materials, such as copper or aluminum, and are electrically connected to the shielding housing 11 to ensure shielding continuity. Cables are distributed to different channels according to their type; for example, power lines are placed in one distribution channel 122, and signal lines in another distribution channel 122, to reduce electromagnetic interference. In other embodiments, the spacing of the metal partitions 121 can be adjusted to accommodate cables of different sizes.

[0037] One end of the metal partition 121 is a connection end that connects to the computer room body 10 or the shielding housing 11, and the other end is an assembly end. The shielding housing 11 or the computer room body 10 is provided with an assembly slot 111 that matches the assembly end. Specifically, the design of the assembly slot 111 makes the installation of the metal partition 121 more convenient and secure. The slot structure enables rapid assembly and reliable contact, reduces installation errors and shielding gaps, and ensures electrical continuity between the metal partition 121 and the shielding housing 11 or the computer room body 10, thereby maintaining the overall shielding performance. It can be understood that the metal partition 121 is fixed by insertion to ensure a good electrical connection; during installation, simply inserting the assembly end into the assembly slot 111 is sufficient to isolate and enclose the cables.

[0038] The assembly slot 111 is provided with a flexible conductive layer. Specifically, the flexible conductive layer in the assembly slot 111 can fill the gap between the assembly end and the assembly slot 111, providing better electrical contact, improving the reliability and stability of the insertion, reducing electromagnetic leakage, and ensuring a long-term stable shielding effect. It is understood that the flexible conductive layer can be made of conductive rubber, metal mesh, or conductive foam. It is compressed during insertion to fill tiny gaps, ensuring a low-resistance connection and thus maintaining shielding integrity. In other embodiments, the conductive layer can be designed to be replaceable for easy maintenance.

[0039] Distribution channels 122 are formed between the metal partitions 121. The distribution channels 122 include horizontal and vertical distribution channels, which can connect to form a cross-shaped distribution port. Specifically, the distribution channels 122 formed between the metal partitions 121 include horizontal and vertical distribution channels, which can connect to form a cross-shaped distribution port, allowing cables to flexibly cross and distribute within the shielding layer 12, adapting to the cable connection needs of different devices, reducing cable bending and tangling, facilitating wiring and maintenance, and improving the efficiency of cable management and the space utilization of the shielding layer 12. It is understood that the horizontal and vertical distribution channels form distribution ports at their intersections, where cables can change direction or branch into different channels, thereby achieving efficient space utilization and flexible wiring paths. In other embodiments, the distribution channels 122 can be designed in other shapes, such as T-shaped, Y-shaped, or ring-shaped, to adapt to specific wiring requirements.

[0040] The interface 131 includes at least one of a power filter interface, a signal filter interface, and a fiber optic waveguide interface. Specifically, it supports secure access for various cables, providing corresponding filtering and shielding for different cable types. The power filter interface suppresses electromagnetic interference from power lines, the signal filter interface protects signal lines from interference, and the fiber optic waveguide interface allows optical signals to pass through without electromagnetic leakage, thus comprehensively improving the anti-interference capability of the shielded room and solving electromagnetic compatibility problems caused by cable introduction. It is understood that the power filter interface has a built-in low-pass filter to filter out high-frequency noise on the power line; the signal filter interface is designed for signal frequencies to prevent external interference; and the fiber optic waveguide interface uses a metal waveguide to allow optical signals to pass through while blocking electromagnetic waves, ensuring no leakage. In other embodiments, the type and number of interfaces 131 can be customized according to specific applications, such as adding coaxial cable interfaces or network interfaces and integrating corresponding filters.

[0041] The walls of the shielding interlayer 12 are coated with a paramagnetic material coating. Specifically, the paramagnetic material coating on the walls of the shielding interlayer 12 can effectively absorb and attenuate low-frequency magnetic fields, compensating for the insufficient magnetic field shielding of metal shields and improving the shielding effect against broadband electromagnetic interference. It is understood that paramagnetic materials, such as manganese-zinc ferrite, have high permeability at high frequencies and can absorb magnetic field energy and convert it into heat, thereby attenuating low-frequency electromagnetic interference; the coating is applied to the inner wall of the shielding interlayer 12 by spraying or pasting.

[0042] The main body 10 of the equipment room is also equipped with an equipotential grounding busbar module 14. The shielding interlayer 12 is connected to the equipotential grounding busbar module 14, and the equipotential grounding busbar module 14 is electrically connected to the main body 10 of the equipment room and the earth grounding electrode through a grounding conductor. Specifically, the setting of the equipotential grounding busbar module 14 forms an equipotential connection between the shielding interlayer 12, the main body 10 of the equipment room, and the earth grounding electrode, eliminating potential differences between the parts, preventing ground loop interference, and providing a discharge path for lightning strikes or surge currents, thereby enhancing the safety and stability of the shielded equipment room. It can be understood that the equipotential grounding busbar module 14 is usually made of copper busbar or conductive strip, and all grounding conductors are connected to it to ensure that all parts are at the same potential; when current surges in, it is conducted to the earth through the grounding conductor.

[0043] An environmental monitoring module is installed outside the main body 10 of the computer room, and this module is connected to an alarm device. Specifically, the environmental monitoring module outside the main body 10 can monitor environmental parameters around the computer room in real time, such as electromagnetic interference levels, temperature, and humidity. By connecting to the alarm device, it can promptly issue an alarm in case of abnormalities, facilitating maintenance personnel to take appropriate measures and ensuring the reliable operation of the shielded computer room. It is understood that the environmental monitoring module may include sensors such as electromagnetic field sensors and temperature and humidity sensors. Data is transmitted to the alarm device via wired or wireless means, and an alarm is triggered when a parameter exceeds a threshold. In other embodiments, the environmental monitoring module can integrate more sensors, such as vibration sensors or smoke detectors, to comprehensively monitor the computer room environment, or the alarm device can be connected to a network to achieve remote monitoring and notification.
