| description | The physical structure of IGBT module package was introduced, and the main mechanism of chip failure caused by heat shock was analyzed. The main transfer path of chip heat loss was analyzed, the transient heat-transfer model of each link of heat transfer was established, and the calculation method of transient temperature rise of each link was given respectively. The heat transfer model of heat pipe radiator cooled by the moving vehicle wind was complex, so the detailed analysis and experimental study were carried out particularly.An effective method to obtain the real-time parameters of the radiator thermal impedance model was found. Finally, the calculation method of transient junction temperature was summarized and the software tool was developed. The calculation method and software tools introduced can be widely applied and provide important reference for transient chip temperature calculation of IGBT module. |
