摘要
针对舰载设备在极端环境下面临的散热和抗冲振难题,本文研究了一种舰载壁挂式风冷机箱,通过采用旋转机构的设计,在有限的空间内实现了LRM模块的侧向插拔与前向维护,提高了设备的实用性与可维护性。机箱采用分离式设计,将发热量大的功放模块和旋转机架拆分开,分别使用独立风道。采用FloEFD进行仿真,在55℃高温环境下,核心器件的壳温温升控制在10℃以内。在抗冲振方面,旋转机架采用三点支撑稳定结构,机箱采用铸铝ZL114A整体铸造的主框架和钛合金铰链机构,提升了结构强度和抗冲击性能。采用ANSYS仿真计算,验证了机箱的抗冲振设计满足设计要求。本文提出的舰载壁挂式风冷机箱设计,有效地解决了舰载机箱的散热与抗冲振问题,可为其他同类设备的结构设计提供参考。
To address the challenges of thermal management and shock/vibration resistance in extreme shipboard environments,this paper presents a shipborne wall-mounted air-cooled cabinet.By incorporating a rotating mechanism,the design enables lateral insertion/extraction of LRM modules and front maintenance within confined spaces,enhancing equipment practicality and maintainability.The cabinet adopts a split configuration that physically isolates high-heat-dissipation amplifier modules from the rotating rack,each utilizing independent air ducts.FloEFD simulations demonstrate that under 55℃ambient conditions,the case temperature rise of core components remains below 10℃.For shock/vibration resistance,the rotating rack employs a three-point support stabilization structure,while the cabinet utilizes an integrally cast aluminum ZL114A main frame and titanium alloy hinge mechanism,significantly improving structural strength and impact resistance.ANSYS simulations validate compliance with design requirements.This proposed solution effectively resolves thermal and shock/vibration challenges for shipboard cabinets,providing a valuable reference for structural design of similar equipment.
