Abstract：

An　investigation　on　the　design,　thermal　performance　(time　constant　and　efficiency)　and　flow　resistance　characteristic　of　a　novel　type　of　CPC　(Compound　Parabolic　Concentrator)　solar　air　collector　by　using　flat　micro-heat　pipe　arrays　(FMHPA)　was　carried　out　theoretically　and　experimentally.　Instantaneous　efficiency　and　flow　resistance　curves　are　obtained　in　the　study.　The　experimental　results　showed　that　the　heat　collecting　efficiency　of　the　collector　is　approximately　53%　in　spring.　And　the　flow　resistance　is　less　than　22　Pa　when　the　air　flow　rate　is　less　than　320　m3/h.　Moreover,　the　time　constant　of　the　collector　is　about　16　min　with　the　air　flow　rate　of　260　m3/h.　©　2015,　Science　Press.　All　right　reserved.
