To　improve　the　heat　transfer　in　the　adsorption　bed　that　was　applied　in　a　solar　adsorption　cooling　system,　an　experimental　study　was　conducted　on　the　finned　adsorption　bed　with　the　SAPO-34　zeolite-water　as　the　working　pair.　In　windless　and　sunny　weather　conditions,　the　performance　of　the　system　was　investigated　for　different　cases　of　the　fin　number　changing　from　2　to　8,　given　a　fixed　fin　height　and　fin　thickness.　The　experimental　results　revealed　that　not　only　the　cooling　capacity,　but　also　the　coefficient　of　the　performance　(COP)　as　well　as　the　specific　cooling　power　(SCP)　of　the　system,　were　improved　obviously　with　the　increment　of　the　fin　number.　With　the　heat　transfer　enhancing　effect　of　the　inserted　fins,　the　bed　cooling　time　following　the　desorption　process　was　greatly　reduced.　Although　the　solar　energy　input　in　the　preheating　and　the　desorption　process　was　increased　for　the　fin-enhancing　cases,　the　comprehensive　result　of　the　cycle　performance　was　revealed　to　be　profitable.
