摘　　要：文中阐述了微通道冷板的结构设计原则,给出了一种适用于微通道冷板的机械加工及焊接工艺方案。对冷板试验样件进行了焊接质量、密封性及强度检测试验,确定了其结构设计变量的合理取值。通过对比两种工艺性结构形式下冷板试验样件的散热性能数据,得到了微通道冷板焊接方案的选用方法,相关结论可为同类型的冷板设计提供工程设计参考。The structural design principles of micro-channel cold plate are discussed, and a machining and welding technology scheme for the micro-channel cold plate is presented in this paper. The reasonable struc- tural design variables are determined based on the prototype experiments of welding quality, sealing and strength. Comparative analysis are performed based on the heat dissipation data of the cold plates machined from two kinds of processing programs, and the method for choosing the welding schemes of cold plate is ob- tained. The conclusions in this paper can provide reference for similar projects.
