为研究内置翅片型Trombe墙对降低室内供暖能耗的贡献率，以兰州地区普通民宅为研究对象，通过在Trombe墙吸热面上布置翅片来强化传热，从而达到改善室内热环境的目的。结果表明：高度为20 mm、横向间距为0.20 m、纵向间距为0.533 m、顺排布置的等腰直角三角形翅片对Trombe墙传热性能及房间热环境的改善效果最好。在整个模拟时段，翅片型Trombe墙吸热面(Nu) ?比无翅片Trombe墙吸热面(Nu) ?最高提升了21.28。与普通房间相比，无翅片Trombe墙房间和翅片型Trombe墙房间节能率分别为36.38%和44.63%，即翅片型Trombe墙房间相对于无翅片Trombe墙房间的节能率提升了8.25%。本研究对于推进太阳能丰富地区清洁能源利用进程具有重要的理论参考价值。

In order to study the contribution rate of built-in fin-type Trombe wall to reducing indoor heating energy consumption, taking ordinary residential houses in Lanzhou as the research object, fins are arranged on the heat absorption surface of Trombe wall to enhance heat transfer, so as to achieve the purpose of improving indoor thermal environment. The results show that the isosceles right-angled triangular fins with a height of 20 mm, a transverse spacing of 0.20 m, a longitudinal spacing of 0.533 m, and an in-line arrangement have the best improvement effect on the heat transfer performance of the Trombe wall and the thermal environment of the room. During the entire simulation period, the fin-type Trombe wall heat absorbing surface (Nu) ? is up to 21.28 higher than the finless Trombe wall heat absorbing surface (Nu) ?. Compared with the ordinary room, the energy saving rate of the finless Trombe wall room and the fin-type Trombe wall room is 36.38 % and 44.63 % respectively, that is, the energy saving rate of the fin-type Trombe wall room is 8.25 % higher than that of the finless Trombe wall room. This study has important theoretical reference value for promoting the process of clean energy utilization in solar-rich areas.
