基于镍铜基毛细芯的环路管研究 Title:ResearchonNickel-CopperBasedCapillaryLoopHeatPipes Abstract: Thecapillaryloopheatpipe(CLHP)technologyhasgainedsignificantattentioninrecentyearsduetoitsexcellentheattransferandthermalmanagementcapabilities.ThispaperfocusesontheresearchandanalysisofCLHPsbasedonnickel-copper(Ni-Cu)wicks,highlightingtheirdesign,operatingprinciples,andemergingapplications.ThestudyaimstocontributetotheunderstandingofNi-CuCLHPs'performanceandpotentialforvariousindustries. Introduction: Theever-increasingdemandforcompactheattransferdeviceshasledtothedevelopmentofadvancedthermalmanagementsystems.CLHPshaveemergedasoneofthemostpromisingtechnologiesowingtotheirhighheattransferefficiency,minimalthermalresistance,andpassiveoperation.Inrecentyears,researchershaveexploredvariousmaterialsforthecapillarywick,andthecombinationofnickelandcopperhasshowngreatpotentialinachievingimprovedheattransfercharacteristics. DesignandConstructionofNickel-CopperWick: TheNi-Cuwick,asthecrucialcomponentofaCLHP,playsasignificantroleinguidingtheworkingfluidandensuringefficientheattransfer.ThepaperdiscussesthedesignconsiderationsandfabricationtechniquesemployedtodevelopNi-Cuwicks,includingsintering,electroforming,andpowdermetallurgy.Thesemethodsallowthecontrolofporesize,porosity,andstructuralintegrity,thusenhancingthewick'scapillaryactionandheattransferperformance.
