摘　　要：针对某舰载加固服务器样机高温试验过程中CPU温度过高导致的报警问题,在实测CPU传热路径的温升占比值及分析组装式热管冷板传热特征基础上,确定组装式热管冷板热阻过大是导致CPU超过允许温升的主要原因。采用蒸汽腔均热板导热柱和内外框架结构对舰载加固服务器进行热设计优化,利用Ansys Icepak建立了数值样机模型并进行网格独立性检验和热仿真分析。结果表明:改进后CPU温升值降低了7.8℃,验证了热设计优化可行性,缩短了研发周期,为类似型舰载加固服务器设计提供了参考。According to the alarm problem caused by the higher CPU temperature of a shipboard rugged server prototype,based on test of the equivalent temperature rise proportion of the CPU heat transfer path and analysis of the assembled heat pipe cold plate heat conduction characteristics,the excessive heat resistance of the assembled heat pipe cold plate is mainly reason.The shipboard rugged server was optimized for thermal design based on VC conduction column,and mesh independence is validated and thermal simulation is completed by Ansys Icepak.The analysis results show that;the CPU temperature rise of the optimized shipboard Tugged server is reduced by 7.8℃,which verifies the practicability of the thermal design improvement,shortens the research and development cycle,and provides a reference for the design of the similar shipboard rugged server.
