In　this　study,　a　novel　flat　plate　solar　collector　with　micro　heat　pipe　array　was　proposed.　One　such　flat　plate　solar　collector　shows　many　advantages,　such　as:　much　cheaper,　absence　of　freezing,　high　pressure　resistance,　easy　integration　into　buildings　etc.　A　thermal　performance　experimental　study　was　conducted,　focusing　on　the　collector　efficiency.　The　results　showed　that　the　collector＇s　maximum　instantaneous　efficiency　is　up　to　83.1%　and　the　total　heat　loss　factor　is　4.77.　A　CFD　model　was　developed　to　analyze　the　fluid　flow　and　heat　transfer　within　the　collector,　the　instantaneous　efficiency　was　compared　with　experimental　results　and　there　is　a　good　agreement.　Optimal　study　was　conducted　for　the　heat　exchanger　with　dry　type　by　CFD　simulation,　and　the　results　showed　that　the　optimal　mass　flow　rate　is　0.1-0.2　kg/(m2·s),　and　the　heat　exchanger　with　fins　has　better　efficiency　at　low　mass　flow　rate　than　without　fins.
