機箱機柜作為電氣與電子設備的物理載體，其設計邏輯遠不止“一個鐵箱子”那么簡單。從結構力學到電磁兼容，從散熱設計到標準化尺寸，每一處細節都關乎內部設備能否長期穩定運行。

As the physical carrier of electrical and electronic equipment, the design logic of chassis cabinets is far more than just a simple "iron box". From structural mechanics to electromagnetic compatibility, from heat dissipation design to standardized dimensions, every detail is related to the long-term stable operation of internal equipment.

在結構設計層面，機柜需綜合考慮靜態載荷與動態載荷。根據GB/T 18663.4-2022《電子設備機械結構 公制系列和英制系列的試驗 第4部分：模數機柜的性能等級組合》，機柜系統需在IP代碼、氣候等級、靜態和動態載荷試驗、電磁屏蔽和地震要求等方面滿足不同防護等級的組合要求。通過采購具有特定性能等級的機柜，可以確保非常佳經濟的解決方案?？蚣艽罱ㄔO計在電氣柜結構設計中占據舉足輕重的地位——框架不但影響內部空間布局與外殼制作結構，機柜的負載能力也往往受框架搭建設計的影響。

At the structural design level, the cabinet needs to consider both static and dynamic loads comprehensively. According to GB/T 18663.4-2022 "Mechanical Structure of Electronic Equipment - Tests for Metric and Imperial Series - Part 4: Performance Level Combination of Modular Cabinets", the cabinet system needs to meet the combination requirements of different protection levels in terms of IP code, climate level, static and dynamic load tests, electromagnetic shielding, and seismic requirements. By purchasing cabinets with specific performance levels, the best economical solution can be ensured. The framework construction design plays a crucial role in the structural design of electrical cabinets - the framework not only affects the internal spatial layout and shell manufacturing structure, but also the load capacity of the cabinet is often affected by the framework construction design.

標準化是機箱機柜設計的另一核心維度。GB/T 3047.1-1995規定了高度進制為20mm的面板、架和柜的基本尺寸系列。寬度為375mm至500mm的模數化電氣機柜，其尺寸、驗證樣品、試驗條件、要求、試驗及合格判定等均有明確標準可循。這種標準化使儀表成套裝置安裝有格距、連線有方位、組配有尺度。

Standardization is another core dimension of chassis and cabinet design. GB/T 3047.1-1995 specifies the basic dimension series for panels, racks, and cabinets with a height base of 20mm. Modular electrical cabinets with a width of 375mm to 500mm have clear standards for size, validation samples, testing conditions, requirements, testing, and qualification determination. This standardization enables the installation of instrument sets with grid spacing, directional connections, and assembly dimensions.

從功能維度看，現代機柜設計還需兼顧電磁兼容與散熱問題。由于電子通信設備的電磁兼容和散熱挑戰，機柜結構設計被提出了不同于一般機電產品的要求——解決機柜內電子器件的良好散熱、防止電路模塊間的電磁干擾，是保證設備正常穩定運行的重要手段。高性能機柜還需具備抗振動、耐沖擊、抗震能力，某些應用場景甚至要求達到BellCore非常出彩別Zone 4的抗震標準。屏蔽性能方面，優秀機柜可達到60dB/1GHz，優于標準30dB/1GHz的要求。從選材到成型，從表面處理到裝配檢驗，每一道工序都決定了機柜非常終能否勝任其所承載的使命。

From a functional perspective, modern cabinet design also needs to consider electromagnetic compatibility and heat dissipation issues. Due to the electromagnetic compatibility and heat dissipation challenges of electronic communication equipment, the design of cabinet structure has been proposed with requirements different from general electromechanical products - solving the good heat dissipation of electronic components inside the cabinet and preventing electromagnetic interference between circuit modules are important means to ensure the normal and stable operation of equipment. High performance cabinets also need to have vibration resistance, impact resistance, and seismic resistance. Some application scenarios even require meeting the seismic standards of Zone 4, the highest level of BellCore. In terms of shielding performance, excellent cabinets can reach 60dB/1GHz, far exceeding the standard requirement of 30dB/1GHz. From material selection to molding, from surface treatment to assembly inspection, each process determines whether the cabinet can ultimately fulfill its mission.
