摘　　要：随着大功率电力电子器件(如绝缘栅双极型晶体管,IGBT)轻量化、小型化和集成化的发展需求,其功率密度越来越大,导致其热流密度越来越高,亟需高效散热来满足其使用要求。传统空气冷却散热器结构简单、使用方便,但是散热能力较低,难以满足高热流密度的散热需求,目前主要采用液体冷却散热器,其中液冷针翅散热器是最常用的高效散热器。本文介绍了液冷针翅散热器的结构、液体工质、材料和制造等方面的研究进展,重点分析了液冷针翅散热器的流体通道结构、针翅结构对流动和传热性能的影响,并给出了液冷针翅散热器的发展建议。With the development of high-power power electronic devices(such as insulated gate bipolar transistors,IGBT)lightweight,miniaturization and integration needs,their power density is increasing,resulting in higher and higher heat flow density,which urgently needs efficient heat dissipation to meet its use requirements.Traditional air-cooled heat sinks are simple in structure and easy to use,but the heat dissipation capacity istoo low to meet the heat dissipation requirements of high heat flow density,so liquid-cooled heatsinks are mainly used at present,among these liquid-cooled pin-fin heatsinks are the most common and efficient heat dissipation facilities.Here introduces the research progress in the structure,liquid working medium,material and manufacturing of liquid-cooled pin-fin heatsinks,focuses on the influence of fluid channel structure,pin-fin structure on the flow and heat transfer performance of liquid-cooled pin-fin heatsinks,and gives suggestions for the development of liquid-cooled pin-fin heatsinks.
