To　improve　the　thermal　performance　of　solar　air　collectors　by　reducing　heat　leakage　and　fully　transporting　the　heat　absorbed　in　the　evaporation　section,　this　paper　proposes　a　structural　innovation　based　on　previous　research,　that　is,　L-shaped　dual　micro　heat　pipe　arrays　integrated　with　a　flat-plate　solar　air　collector　with　a　double　glazing　cover.　Experiments　are　conducted　to　investigate　the　thermal　performance　of　the　proposed　collector.　The　effects　of　solar　irradiation,　ambient　temperature,　and　air　flow　rate　on　thermal　performance　are　reported.　Thermal　resistance　is　analyzed　theoretically.　The　application　performance　of　the　collector　is　evaluated　based　on　a　typical　rural　building　heating　model.　The　results　show　that　the　average　heat　collection　efficiency　is　49.72　%,　55.69　%,　59.37　%,　and　61.48　%　for　air　flow　rates　of　80,　120,　160,　and　200　m3/h,　respectively.　The　evaporation　section　temperature　is　reduced　by　a　maximum　of　25.28　°C　under　flow　rates　of　200　m3/h.　The　performance　of　the　solar　collector　is　more　significantly　influenced　by　solar　irradiance　than　by　ambient　temperature.　The　average　thermal　efficiency　is　linearly　related　to　the　normalized　temperature　difference.　The　CO2　reduction　over　the　lifetime　of　the　device　is　15040.09,　19287.80,　and　5662.95　kg　compared　with　the　use　of　conventional　bulk　coal,　electricity,　and　natural　gas,　respectively.　©　2024　Elsevier　Ltd
