【摘要】 以基于片状Diamond和杆状Diamond结构的复合相变储热单元（TPMS-PCM）为研究对象，建立4个模型，分别为不同模型倾角（0°、30°、60°、90°）。通过数值模拟的方法，研究模型倾角对相变储能单元储能性能的影响规律。研究结果表明：基于片状Diamond的相变储能单元自然对流较弱，因此其受模型倾角影响较小；在杆状Diamond中，60°模型融化速度比0°模型提高5.9%。更多还原

【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.更多还原
