A　type　of　compound　parabolic　concentrator　integrated　collector-storage　solar　air　heater　was　presented　in　this　paper,　which　took　flat　micro　heat　pipe　arrays　as　the　core　heat　transfer　element,　combined　with　compound　parabolic　concentrator　and　latent　heat　storage　unit.　The　system　took　compound　parabolic　concentrator　vacuum　tube　collector　as　the　heat　collecting　part,　58#　paraffin　as　the　latent　heat　storage　material,　and　the　lap　joint-type　flat　micro　heat　pipe　arrays　as　the　core　heat　transfer　element.　The　thermal　storage　and　release　performance　of　the　system　under　two　different　modes　(discharging　after　charging　and　charging　while　discharging　mode)　was　tested　outdoors.　According　to　the　change　of　the　azimuth　angle　of　the　sun　incident　lights,　combined　with　the　incident　half　angle　θ　of　the　concentrator,　the　time　range　of　the　total　solar　radiation　absorbed　by　the　concentrator　was　determined,　and　the　absorption　model　of　the　solar　radiation　energy　by　the　compound　parabolic　concentrator　was　established.　Results　show　that　under　the　mode　of　charging　after　discharging,　the　solar　radiation　absorbed　by　the　collector　is　about　15　MJ,　the　average　heat　storage　efficiency　is　about　36%,　and　the　change　of　air　flow　has　little　influence　on　the　daily　total　efficiency　of　the　device,　maintaining　at　about　34%.　Under　the　mode　of　charging　while　discharging,　with　the　increase　of　air　volume　flow,　the　useful　energy　extracted　increases,　and　the　daily　total　efficiency　of　the　device　increases.　When　the　air　flow　is　110　m3/h,　the　useful　energy　extracted　is　7.07　MJ,　and　the　daily　total　efficiency　is　45.6%.　©　2022,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
