Phase Change Cooled Encapsulation Material FC-72 Pyrolysis Process Simulation

Le résumé fourni par la source

In view of the phenomenon that the internal medium of power electronic devices applying immersion phase change cooling technology has been boiling during operation, it is necessary to carry out research on whether long-term boiling of the medium will lead to the pyrolysis of the medium and the pyrolysis process and products when the medium is pyrolyzed. In this paper, 25 FC-72 simulated molecular models are set up in the ReaxFF force field by molecular dynamics simulation method to study the dynamic pyrolysis process of FC-72 at different temperatures, and the following conclusions are drawn by analyzing the pyrolysis products: the pyrolysis process mainly generates some small molecule gases such as CF4 and F2, and the reaction process is significantly accelerated with the increase of temperature, the higher the temperature, the more C6F14 participates in pyrolysis, and the faster the reaction system reaches stability.
