直流屏機柜的結構設計，圍繞功能實現與場景適配展開，從柜體材質、內部布局到散熱防護，每一個環節都經過精心考量，既保障設備的穩定運行，又滿足不同安裝場景的需求，實現性能與實用性的平衡。

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.

直流屏機柜柜體材質與結構強度是穩定運行的基礎。直流屏機柜多采用優良冷軋鋼板或鋁合金材質，冷軋鋼板具備良好的強度與剛性，能承受內部設備的重量與外部安裝環境的壓力，同時具備一定的抗腐蝕能力；鋁合金材質則在輕量化與散熱性上更具優勢，適合對安裝空間與散熱有特殊要求的場景。柜體表面經過噴塑、鍍鋅等工藝處理，進一步提高抗腐蝕、抗老化能力，適應室內外多種安裝環境，即便在潮濕、多塵的場所，也能保持柜體結構的完整性，保障內部設備的安全。

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.

內部布局遵循功能分區與運維便捷的原則。機柜內部采用模塊化設計，將整流模塊、直流配電單元、監控模塊、蓄電池組等核心部件合理劃分區域，各模塊之間留有充足的間距，避免相互干擾，同時便于散熱氣流流通。整流模塊集中布置，便于統一管理與維護；直流配電單元采用清晰的接線標識與防護設計，減少接線錯誤的風險，方便運維人員進行回路調整；監控模塊位于便于操作的位置，便于實時查看運行數據與進行參數設置；蓄電池組則采用獨立的安裝空間，配備防護隔板，防止電池漏液影響其他部件，同時預留足夠的檢修空間，方便電池的更換與維護。

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.

散熱與防護設計保障設備長期穩定運行。直流屏機柜內部的整流模塊、配電單元等部件在運行時會產生熱量，若散熱不及時，會影響設備性能與使用壽命。因此，機柜設計了完善的散熱系統，包括自然通風散熱孔、強制散熱風扇等，可根據設備運行溫度自動調節散熱模式，確保機柜內部溫度始終處于合理范圍。同時，機柜具備良好的防護能力，采用密封設計，配備防塵網，有效阻擋灰塵、異物進入柜體內部；針對戶外安裝場景，機柜還具備防水、防雨設計，確保在惡劣天氣條件下，內部設備不受影響，保障供電系統的穩定運行。

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.
