An　experimental　study　was　conducted　to　evaluate　the　thermal　performance　of　a　vacuum　tube　solar　air　collector　that　is　based　on　micro　heat　pipe　arrays　(MHPA)　and　features　wavelike　fins　attached　to　the　condenser　section　of　the　MHPA.　The　experimental　results　were　used　to　analyze　the　thermal　performance　of　the　collector,　particularly　the　temperature　distribution　in　the　different　localizations　of　the　air　collector.　The　heat　loss　analysis　provided　a　useful　parameter　to　evaluate　the　heat　loss　of　the　collector.　Results　showed　that　a　decrease　in　the　inlet,　will　led　to　an　increase　in　efficiency　because　of　the　reduced　heat　losses　to　the　environment.　The　daily　thermal　efficiency　varied　between　50%　and　70%.　In　the　performance　analysis　of　the　MHPA　collector,　varying　flow　rates　were　employed　to　observe　the　change　in　efficiency,　outlet　temperature,　MHPA　temperature　behavior　variation　vs.　solar　radiation,　and　air　flow　rate.　The　utilization　of　the　collector　can　reduce　the　amount　of　emissions　of　gaseous　waste　emissions,　which　has　large　energy　saving　potential　and　environmental　benefits.　The　proposed　MHPA-based　vacuum　tube　solar　air　collector　shows　good　potential　in　large-scale　applications,　such　as　in　the　room　heating　of　farmhouses,　industrial　buildings,　and　remote　outposts,　as　well　as　in　the　agricultural　sector.　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
