A　novel　plate-shaped　ice　thermal　storage　device　is　constructed　with　multichannel　flat　tube.　The　different　temperatures　and　flow　rates　of　heat　transfer　fluid　(HTF)　on　the　variations　in　the　internal　temperature　and　the　store/release　power　are　experimentally　investigated.　Results　indicate　that　the　reduction　in　temperature　of　cold　HTF　from　-3　degrees　C　to　-4　degrees　C　is　notably　to　shorten　the　super-cooling　process,　reduced　the　freezing　time　by　35.04%　and　increased　the　average　storage　power　by　24.9%,　its　effect　gradually　weaken　with　decrease　in　temperature.　Furthermore,　numerical　simulation　and　response　surface　method　are　adopted　to　gain　predictive　models　of　four　response　indices　for　estimating　the　behavior　of　the　device　in　terms　of　five　different　design　parameters,　and　the　interaction　effects　of　design　parameters　on　responses　are　investigated.　Finally,　the　multi-objective　joint　optimization　is　developed　based　on　an　efficient　storage　device　with　goals　of　excellent　thermal　performance　and　thermodynamic　perfection,　while　its　manufacturing　cost　is　low.　The　optimization　results　recommend　the　fin　height,　number　and　thickness　are　30.1　mm,　10,　and　0.5　mm,　respectively,　temperature　and　flow　rate　of　cold　HTF　are　-4.01　degrees　C　and　0.2　m3/h,　respectively,　to　maximize　ice　formation　rate,　exergy　efficiency,　and　fin　efficiency　and　minimize　the　metal　consumption.
