摘要：

This　study　experimentally　investigated　a　new　type　of　ice　storage　device　(ISD)　based　on　flat　micro　heat　pipe　arrays　(FMHPAs).　The　structure　and　working　principle　of　device　were　explained　in　details,　and　test　rig　was　built.　The　applicability　of　FMHPAs　as　the　core　heat　transfer　element　was　experimentally　verified,　the　characteristics　of　temperature　distribution,　cold　storage　power,　cold　storage　capacity　and　cold　storage　density　of　ISD　based　on　FMHPAs　with　different　boiling　temperature　working　fluids　(R141b　and　acetone)　are　compared　and　analyzed.　The　results　showed　that　ISD　based　on　FMHPAs　presented　well　performance.　In　the　same　time,　the　average　cold　storage　power　of　FMHPAs　with　R141b　and　acetone　was　0.14　kW　and　0.187　kW,　respectively,　and　the　cold　storage　capacity　per　unit　mass　was　139.22　kJ•kg-1　and　184.33　kJ•kg-1,　respectively.　The　cold　storage　density　of　ISD　based　on　FMHPAs　with　R141b　and　acetone　was　22.54　J•K-1kg-2　and　17.61　J•K-1kg-2,　their　performance　better　than　ISD　based　on　circular　heat　pipe.　©　All　Right　Reserved.
