摘要
硅基环路热管作为一种高效两相传热装置可应用于集成电路热管理.本文设计并制备了一种硅基微柱阵列毛细结构以期用作硅基环路热管蒸发器,搭建了毛细蒸发实验系统,探究了热流密度以及工作角度等变化对蒸发器传热性能的影响.研究结果发现:热流密度越高,蒸发器启动速度越快,稳定运行温度越高;蒸发器在工作角度180°时的性能优于0°,在工作角度90°时的性能优于270°.本文关于硅基蒸发器性能研究可为后续相关环路热管的优化设计提供数据支撑.
Abstract
As an efficient two-phase heat transfer device,silicon-based loop heat pipe(LHP)caxn be applied to thermal management of integrated circuits.In this study,a silicon-based micropillars array capillary structure is designed and manufactured to be used as a silicon-based LHP evaporator,and an experimental system of capillary evaporation is built to explore the influence of heat flux and working angle on the heat transfer performance of the evaporator.The results show that the higher the heat flux,the faster the start-up speed of evaporator and the higher the stable operation temperature.The performance of the evaporator is better than 0° when the working angle is 180° and better than 270° when the working angle is 90°.The research on the performance of silicon-based evaporator can provide data support for the design and manufacture of silicon-based LHP in the future.
