摘要
高密度能量的输入与管理正成为未来装备可靠和长寿命服役的关键基础,微通道结构热管理部件具有结构紧凑、整体尺寸小、传热效率高等特点,可以很好地解决高能量密度热管理问题,在航空航天以及军工领域有着广阔的应用前景。介绍了不同类型微通道结构对微通道换热器传热性能的影响,综述了传统微米级减材加工技术和增材制造工艺制备复杂微通道热管理部件的优缺点,并重点从化学蚀刻和扩散焊接2个关键工序阐述了叠层增材制造技术在加工复杂微通道热管理部件方面的应用。
High-density energy input and management are becoming the key foundation for reliable and long-life service of future equipment.Thermal management components with microchannel structures have compact structure,small overall size,and high heat transfer efficiency,can well solve the problem of high energy density thermal management and have broad application prospects in aerospace and military fields.The influence of different types of microchannel structures on the heat transfer performance of microchannel heat exchangers is introduced,and the advantages and disadvantages of the traditional micron-level subtractive processing technology and additive manufacturing process for preparing thermal management components with complex microchannel structures are reviewed.The application of stacked additive manufacturing technology in processing thermal management components with complex microchannel structures is described mainly from chemical etching and diffusion welding.
