摘要
介绍了近年来微通道换热器内冷却介质强化换热的研究进展.阐述了纳米流体、液态金属以及潜热型功能热流体强化传热的机理;探讨了影响纳米流体传热性能的因素,包括纳米颗粒的种类、体积分数和温度等;讨论了增大液态金属传热系数的方法;分析了微胶囊壁材、相变材料和微胶囊的质量分数等对潜热型功能热流体热容的影响.指出了3 种冷却介质目前尚存在的缺陷及相应的改善措施,对高热流密度设备散热问题中冷却介质的选取具有一定的指导意义.
Abstract
The present study presents the recent research progress on enhanced heat transfer in microchan-nel heat sinks for cooling media.It describes the mechanisms behind enhanced heat transfer using nanofluids,liquid metals,and latent heat functional fluids.Furthermore,it explores various factors that af-fect the heat transfer performance of nanofluids,such as nanoparticle types,volume fractions,and tempera-tures.Additionally,it discusses methods to increase the heat transfer coefficient of liquid metals and analy-zes how wall materials of microcapsules,phase-change materials,and mass fractions of microcapsules in-fluence the heat capacity of latent heat functional fluids.Moreover,this study highlights the limitations of these three cooling media and proposes corresponding improvement measures.These findings provide valu-able guidance for selecting appropriate cooling media in high heat flux equipment.
