Aiming　at　the　serious　wind　power　curtailment　phenomenon,　this　paper　proposes　an　electric　latent　heat　storage　based　on　phase　change　heat　storage　technology　and　flat　micro-heat　pipe　array　technology.　The　structure　and　working　principle　of　the　device　are　clarified.　The　thermal　characteristics　of　heat　storage　and　heat　release　and　simultaneous　heat　storage　and　release　process　were　studied.　The　new　electric　heat　storage　uses　12　flat　micro-heat　pipe　arrays　with　louver　fins　as　the　heat　transfer　element,　and　the　device　is　filled　with　18　kg　of　67#　industrial　paraffin.　Heat　storage　conditions　use　different　heating　powers　(0.2∼2.0　kW)　to　heat　the　electric　heat　storage,　and　control　the　volume　flow　of　air　(20∼120　m3/h)　and　the　temperature　of　the　air　(15∼27C)　to　take　away　heat.　The　test　results　show　that　the　new　electric　heat　storage　operates　efficiently　and　stably　under　different　operating　mode.　The　heat　storage　and　heat　extraction　efficiency　could　reach　99%　and　89%　operating　at　charging　and　discharging　mode　separately　under　the　test　conditions.　©　2023　Science　Press.　All　rights　reserved.
