This　article　presents　an　integrated　collector-storage　solar　air　heater　(ICSSAH)　based　on　lap　joint-type　(LJT)　flat　micro-heat　pipe　arrays　(FMHPA)　and　latent　thermal　storage　(LTS).　FMHPA　for　thermal　collection　and　for　thermal　storage　release　were　separated　and　overlapped.　The　discharging　process　is　not　affected　by　the　length　of　the　collection　segment.　Approximately　21.03　kg　of　52#　industry　paraffin　wax　was　utilized　as　thermal　storage　material　(TSM)　to　store　solar　energy,　and　the　collection　area　was　set　to　1.03　m(2).　The　influence　of　environmental　factors　on　the　charging　process　and　the　effects　of　heat　transfer　fluid＇s　parameters　on　the　discharging　process　were　studied.　An　average　efficiency　curve　was　proposed　according　to　the　analysis　of　experimental　data　to　evaluate　thermal　storage　performance　during　charging,　and　a　correlation　between　Re　and　Nu　was　fitted　to　predict　the　convective　heat　transfer　coefficient　during　the　discharging　of　the　device.　LJT-FMHPA-ICSSAH　exhibits　good　thermal　characteristics　during　experimental　conditions.　The　thermal　storage/extraction　efficiency　reached　73.8%/97.1%,　and　the　average　thermal　storage/extraction　power　reached　623.7　W/815.9　W.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
