微通道热沉的稳健优化设计

Robust Optimization Design for Microchannel Heat Sinks

将田口稳健设计方法用于硅基微通道热沉的优化设计,建立了微通道热沉的简化性能分析模型,确定了影响其散热性能的关键参数,利用正交试验和信噪比分析实现了参数的稳健优化。利用外部监控程序对CAD和CAE软件的脚本进行动态修改,并且创建专门的进程来执行修改后的脚本,采用共享文件和延时的方法实现主进程、几何建模进程和性能分析进程的同步运行,实现了稳健设计过程的自动化。

Taguchi robust design method was applied to the design of silicon microchannel heat sinks, Reduced model for heat transfer analysis of microchannel heat sinks was built and the key parameters for their heat dissipation performance were identified. Orthogonal experiments were designed and signal-noise ratios were calculated to carry out the robust optimization of the key parameters. To automate robust optimization design, the journal files of CAD and CAE software were modified on the fly by a daemon written in the C language and separate processes were created to play these journal files. The main process, geometrical modeling process and performance analysis process were synchronized through shared files and time delay.
