Thermal management is essential to reliable design of power modules. In this report, a trend in the thermal resistance of power modules was examined by reviewing the current cooling technologies. The thermal resistance of power modules has decreased to approximately 1/3x in 10 years. Our numerical simulation about cooling suggests that a straightforward development in liquid cooling technology can achieve the update corresponds to the expected change in next 5 year when it keeps this trend in next decades. However, further progress in thermal resistance shall require higher thermal-conductive materials for spreader and two-phase cooling technologies.
