Parameter analysis and optimization of a heat sink for cooling intelligent power modules（IPM）based on Taguchi method

The stability of the intelligent power module has a very significant impact on operation air conditioner. In this paper, prototype experimental platform is built to verify feasibility simulation results. Next, thermal performance and flow characteristics heat sink are analyzed, including single-factor analysis interactive effects. results show that smaller pipe diameter can reduce maximum temperature IPM (Timp), but it will increase pressure drop (?P) entropy generation. thickness plate height protruding table have an effect Timp. Then sensitivity Timp different parameters was contribution ratio both largest. Finally, optimal combination obtained minimize drop. Compared with original structure, decreased by 3.98 K.
