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
To evaluate the contribution of a built-in fin-type Trombe wall to reducing indoor heating energy consumption, this study takes a typical residential building in Lanzhou as the research object. Fins are installed on the heat-absorbing surface of the Trombe wall to enhance heat transfer and thereby improve the indoor thermal environment. The results show that the isosceles right-triangle 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 configuration provide the greatest improvement in heat transfer performance and indoor thermal conditions. Over the entire simulation period, the average Nusselt number (
