Heat Dissipation Characterization of Heat Generating Element Coupled with Solid-Solid Phase Transition Material VO2

Abstract

This paper describes the feasibility of dynamic thermal control using solid-solid phase change heat storage materials. Vanadium dioxide VO2, which is one of the solid-solid phase transition materials, has a large latent heat and can be used as a temperature leveling element for electronic devices. In this study, the temperature change of the heat generating element coupled with VO2 was evaluated by a heat transfer simulation and a verification experiment. As a result, it became clear that the time required for the heating element to reach an arbitrary critical temperature can be lengthened by coupling VO2.
