Abstract： To evaluate the contribution of a built-in fin-type Trombe wallto reducing indoor heating energy consumption，this study takes a typical residential building in Lanzhou as the research object.Fins are installd on the heat-absorbing surface of the Trombe wallto enhance heat transfer and thereby improve the indoor thermal environment.The results show that the isosceles right-triangle fins with a height of 20mm ，a transverse spacing of 0.20m ，a longitudinal spacing of 0.533m ，and an in-line configuration provide the greatest improvement in heat transfer performance and indoor thermal conditions.Over theentire simulation period，the average Nusselt number ）of the fin-type Trombe wall is 21.28 higher than that of the finless wall. Compared with a conventional room，theenergy-saving rates of the finless Trombe wall and fin-type Trombe wallrooms are 36.38% and 44.63% respectively， meaning the fin-type Trombe wall yields an additional 8.25% energy-saving improvement.
