Abstract: This study focuses on the thermal management issues of power electronic devices and explores the current status and development of heat dissipation technologies. First, the study begins by classifying power electronic devices and analyzing the necessity of their thermal management as well as the evolution of heat dissipation technologies. Furthermore, through the analysis of the thermal characteristics of electronic chips and components, a heat dissipation path model is established, along with corresponding thermal characteristic testing methods, providing a theoretical basis for research on heat dissipation technologies. The research emphasizes the limitations of traditional heat dissipation technologies and the application potential of new thermal materials and innovative structural designs. Through experimental validation and simulation model analysis, this paper establishes a series of feasible improvement plans for heat dissipation technologies. Comparative results show a significant reduction in the operating temperature of power electronic devices, enhancing system stability and safety. The findings of this study are expected to provide scientific guidance and technical support for the thermal management practices in the field of electrical engineering.
