Phase change material considered as a novel energy transport material can be used for modern energy storages. Nowadays, the energy transport enhancement can be achieved using the extended heat transference surface. The present research is devoted to numerical simulation of thermal convection of nano-encapsulated phase change material within a square differentially-heated chamber under an influence of solid fins of different location, sizes and number. The governing equations of conjugate convective energy transport written using the non-dimensional primitive variables have been worked out by the finite element technique. The developed computational code has been verified employing computational and experimental results of other authors. Impacts of number of solid fins (1 ≤ N_f≤ 6), aspect ratio of fins (0.1 ≤ γ₁≤ 2.5) and dimentionless melt temperature (0.1 ≤ T_f≤ 0.9) have been studied. It has been found that the heat transference augmentation with the fins number can be found for Ra = 10⁴, while for Ra = 10⁵ a rise of the fins number reduces the mean Nusselt number.

相变材料被认为是新型的能量传输材料，可用于现代储能。如今，可以使用扩展的传热表面来实现能量传输的增强。本研究致力于在不同位置，大小和数量的固体散热片的影响下，在方形差热室内纳米封装相变材料的热对流的数值模拟。利用有限元技术计算出了使用无量纲原始变量写的共轭对流能量传输的控制方程。所开发的计算代码已经使用其他作者的计算和实验结果进行了验证。固体翅片的数量的影响（1个≤ Ñ _˚F≤6），纵横翅片比（0.1≤ γ ₁ ≤2.5）和量纲熔融温度（0.1≤ Ť _˚F ≤0.9）进行了研究。已经发现，对于Ra＝ 10 ⁴，可以发现随着翅片数的传热增加，而对于Ra＝ 10 ⁵，翅片数的增加减小了平均努塞尔数。
