碳系复合纳米流体于光伏/光热集热器中的应用
Research on the application of carbon composite nanofluids in photovoltaic photothermal collectors
摘要
Abstract
Carbon-based nanofluid has a higher heat transfer coefficient than other nanofluids and is relatively cheap.Graphene nanofluid has a high heat transfer coefficient,and reduced graphene oxide nanofluid has good stability.So,this article developed a new type of carbon-based composite nanofluid(water-based graphene/reduced graphene oxide composite nanofluid)as the heat transfer medium in PV/T collectors by two-step method.The radiation intensity,flow rate,and composite nanofluid were analyzed.The effect of proportion on the water temperature at the outlet of the collector was studied,and the proportion of water-based graphene/reduced graphene oxide with better heat transfer performance was obtained in different compound proportion ranges of the experiment.Experimental results show:the higher the radiation intensity,the faster the flow rate,the higher the water temperature at the outlet of the PV/T collector,the better the heat transfer effect of the nanofluid;when the composite ratio is 8:2,the heat transfer effect of the nanofluid is the best,the thermal efficiency and electrical efficiency of the PV/T system are 23.49%and 20.18%respectively.Compared with water-based graphene and reduced graphene oxide,nanofluid has better heat transfer effect.The research of this article provides reference for the practical development of carbon nanofluids in heat transfer media.关键词
