Abstract: Based on the National Energy Storage Technology Industry-Education Integration Innovation Platform, aimed at undergraduate students in energy storage science and engineering, a visual phase change heat storage teaching experiment platform based on paraffin solid-liquid phase change is established in this paper. The teaching links such as experimental principle, experimental equipment, experimental operation steps, experimental data processing and calculation and error analysis are designed. Through the combination of heat and mass transfer with hands-on practice, it can strengthen the students’ knowledge and understanding of the basic principle of energy storage and release of phase change heat storage and the evolution of solid-liquid phase interface in the process of phase change heat storage. Meanwhile, the students' participation and problem-solving ability are improved. The experimental platform has perfect functions and strong operability, which can deepen students’ understanding of the theoretical teaching content related to the energy storage field. It can also meet the needs of disciplinary experimental teaching and students' research practice, further providing an important reference for the development of experimental teaching in the energy storage science and engineering major.
