A　novel　thermal　storage　solar　air　heater　(TSSAH)　is　proposed　in　this　study.　This　TSSAH　is　composed　of　a　vacuum　glass　tube,　flat　micro-heat　pipe　arrays　(FMHPA),　and　a　thermal　storage　material　(i.e.,　paraffin)　with　a　phase　change　temperature　of　58　degrees　C.　The　FMHPA　acts　as　the　core　heat　transfer　component.　Considering　the　low　heat　conductivity　coefficient　of　paraffin,　louver　fins　are　utilized　to　enhance　heat　transfer.　Thermal　performance　is　analyzed　and　discussed.　During　thermal　collection,　natural　convection　evidently　contributes　to　enhancing　heat　transfer.　Increasing　solar　radiation　intensity　can　improve　collection　efficiency.　Thermal　collection　efficiency　increases　from　70.22%　to　77.28%　when　solar　radiation　is　increased　from　675　W/m(2)　to　835　W/m(2)　under　an　ambient　temperature　range　of　20.8　degrees　C-23.3　degrees　C.　A　high　ambient　temperature　results　in　high　collection　efficiency　that　can　reach　80.59%.　During　thermal　discharge,　enhancing　the　air　volumetric　flow　rate　can　evidently　increase　the　amount　of　useful　energy　and　shorten　discharge　time.　From　80　m(3)/h　to　170　m(3)/h,　the　amount　of　useful　energy　is　increased　from　335　W　to　550　W,　and　discharge　time　is　shortened　from　309　min　to　195　min　under　inlet　temperatures　ranging　from　24.1　degrees　C　to　24.2　degrees　C.　A　high　inlet　temperature　generates　a　high　outlet　temperature　but　decreases　the　amount　of　useful　energy.　From　19.7　degrees　C　to　32.0　degrees　C,　outlet　temperature　is　increased　from　30.4　degrees　C　to　36.6　degrees　C,　and　the　amount　of　useful　energy　is　reduced　from　692　W　to　287　W　at　an　air　volumetric　flow　rate　of　200　m(3)/h.　During　thermal　discharge,　the　average　amount　of　useful　energy　can　reach　692　W　at　an　inlet　temperature　of　19.7　degrees　C　and　an　air　volumetric　flow　rate　of　200　m(3)/h,　indicating　that　the　proposed　TSSAH　can　release　heat　quickly.　In　the　experiment　scale,　the　discharged　heat　is　6150-6450　kJ　at　a　phase　change　material　temperature　scale　of　85　degrees　C-35　degrees　C.　(C)　2021　Elsevier　Ltd.　All　rights　reserved.
