直流屏机柜的结构设计，围绕功能实现与场景适配展开，从柜体材质、内部布局到散热防护，每一个环节都经过精心考量，既保障设备的稳定运行，又满足不同安装场景的需求，实现性能与实用性的平衡。

The structural design of the DC screen cabinet revolves around functional implementation and scene adaptation. From cabinet material, internal layout to heat dissipation protection, every aspect has been carefully considered to ensure the stable operation of the equipment and meet the needs of different installation scenarios, achieving a balance between performance and practicality.

直流屏机柜柜体材质与结构强度是稳定运行的基础。直流屏机柜多采用优良冷轧钢板或铝合金材质，冷轧钢板具备良好的强度与刚性，能承受内部设备的重量与外部安装环境的压力，同时具备一定的抗腐蚀能力；铝合金材质则在轻量化与散热性上更具优势，适合对安装空间与散热有特殊要求的场景。柜体表面经过喷塑、镀锌等工艺处理，进一步提高抗腐蚀、抗老化能力，适应室内外多种安装环境，即便在潮湿、多尘的场所，也能保持柜体结构的完整性，保障内部设备的安全。

The material and structural strength of the DC screen cabinet are the foundation for stable operation. DC screen cabinets are often made of high-quality cold-rolled steel plates or aluminum alloy materials. Cold rolled steel plates have good strength and rigidity, can withstand the weight of internal equipment and the pressure of external installation environment, and have a certain degree of corrosion resistance; Aluminum alloy material has more advantages in lightweight and heat dissipation, making it suitable for scenarios with special requirements for installation space and heat dissipation. The surface of the cabinet body has been treated by plastic spraying, zinc plating and other processes to further improve its corrosion resistance and aging resistance and adapt to various indoor and outdoor installation environments. Even in wet and dusty places, the integrity of the cabinet structure can be maintained to ensure the safety of internal equipment.

内部布局遵循功能分区与运维便捷的原则。机柜内部采用模块化设计，将整流模块、直流配电单元、监控模块、蓄电池组等核心部件合理划分区域，各模块之间留有充足的间距，避免相互干扰，同时便于散热气流流通。整流模块集中布置，便于统一管理与维护；直流配电单元采用清晰的接线标识与防护设计，减少接线错误的风险，方便运维人员进行回路调整；监控模块位于便于操作的位置，便于实时查看运行数据与进行参数设置；蓄电池组则采用独立的安装空间，配备防护隔板，防止电池漏液影响其他部件，同时预留足够的检修空间，方便电池的更换与维护。

The internal layout follows the principles of functional zoning and convenient operation and maintenance. The interior of the cabinet adopts a modular design, which divides the core components such as rectifier modules, DC distribution units, monitoring modules, and battery packs into reasonable areas, leaving sufficient spacing between each module to avoid mutual interference and facilitate the circulation of heat dissipation airflow. Centralized arrangement of rectifier modules for easy unified management and maintenance; The DC distribution unit adopts clear wiring identification and protective design to reduce the risk of wiring errors and facilitate operation and maintenance personnel to adjust the circuit; The monitoring module is located in a convenient location for real-time viewing of operational data and parameter settings; The battery pack adopts independent installation space and is equipped with protective partitions to prevent battery leakage from affecting other components. At the same time, sufficient maintenance space is reserved to facilitate battery replacement and maintenance.

散热与防护设计保障设备长期稳定运行。直流屏机柜内部的整流模块、配电单元等部件在运行时会产生热量，若散热不及时，会影响设备性能与使用寿命。因此，机柜设计了完善的散热系统，包括自然通风散热孔、强制散热风扇等，可根据设备运行温度自动调节散热模式，确保机柜内部温度始终处于合理范围。同时，机柜具备良好的防护能力，采用密封设计，配备防尘网，有效阻挡灰尘、异物进入柜体内部；针对户外安装场景，机柜还具备防水、防雨设计，确保在恶劣天气条件下，内部设备不受影响，保障供电系统的稳定运行。

The design of heat dissipation and protection ensures the long-term stable operation of the equipment. The rectifier module, distribution unit and other components inside the DC screen cabinet generate heat during operation. If the heat dissipation is not timely, it will affect the performance and service life of the equipment. Therefore, the cabinet is designed with a comprehensive heat dissipation system, including natural ventilation heat dissipation holes, forced cooling fans, etc., which can automatically adjust the heat dissipation mode according to the operating temperature of the equipment, ensuring that the internal temperature of the cabinet is always within a reasonable range. At the same time, the cabinet has good protective capabilities, adopts a sealed design, and is equipped with dust-proof nets to effectively block dust and foreign objects from entering the interior of the cabinet; For outdoor installation scenarios, the cabinet also has waterproof and rainproof designs to ensure that internal equipment is not affected under adverse weather conditions, ensuring the stable operation of the power supply system.
