A　spiral　coil　cavity　solar　receiver　was　proposed　for　a　dish　solar　concentrator　for　hydrogen　generation　developed　by　Institution　of　Electrical　Engineering,　Chinese　Academy　of　Science.　The　physical　and　mathematical　model　was　established　to　describe　the　process　of　heat　transfer　and　flow　in　the　solar　receiver.　Simulations　were　performed　to　analysis　the　influences　of　the　configuration　parameters　on　the　performances　of　the　solar　receiver　and　the　optimum　values　of　the　configuration　parameters　were　obtained.
