摘要：

In　the　present　study,　the　thermal　characteristics　of　a　novel　electrical　heat　storage　unit　that　utilizes　latent　heat　storage　and　flat　micro-heat　pipe　arrays　(FMHPAs)　was　investigated　experimentally　and　numerically.　Electric　power　was　supplied　to　melt　the　PCM　from　solid　to　liquid.　A　transient　three-dimensional　finite　volume　based　model　using　an　enthalpy-porosity　formulation　is　implemented　to　analyze　the　performance　of　the　proposed　heat　storage　in　charging　process.　The　experimental　and　simulation　results　are　in　good　agreement,　which　proves　the　correctness　of　this　model.　The　effects　of　electrical　heating　power,　fin　height　and　spacing　on　the　thermal　response　of　the　heat　storage　have　been　studied.　The　experimental　and　the　simulation　results　are　in　good　agreement,　and　the　results　of　the　research　could　guide　the　devise　of　the　heat　storage　when　using　FMHPA　as　the　core　element.　©　2018　International　Heat　Transfer　Conference.　All　rights　reserved.
