Abstract

The composite phase change heat storage unit （TPMS-PCM） based on sheet Diamond and rod-Diamond structure was studied, and four models were established for different installation angles （0˚, 30˚, 60˚, 90˚）. The influence of model inclination Angle on the energy storage performance of phase-change energy storage unit is studied by numerical simulation. The results show that the natural convection of the phase change energy storage unit based on the chip Diamond is weak, so it is less affected by the installation Angle. In the rod-shaped Diamond, the melting speed of the 60° model is 5.9% higher than that of the 0° model.
