Abstract

Abstract: Theeffectsofporouswickporosityandheatsourcepoweronstartupand operatingcharacteristicsofcapillarywick evaporator(justlikealoopheatpipewithoutlinkingthevaporline)wasinvestigated.Theexperimentwascarriedoutwithout mixingtheeffectoftheworkingfluidandthecondenser.Theresultshowsthatthetemperatureoftheevaporatorwill fluctuateinsomecasesduringthestartupofthesystem.Theheatsourcepowerwhichmakesthetemperaturefluctuated decreasinglywiththeincreasingporosityoftheporouswick.Whenporouswickisthesame,temperatureiseasierto fluctuateanditwillbemuchseriouswith the biggerheatsourcepower.Thereasonforthetemperaturefluctuationisthatthe porosity of porous wick does notmatchwiththeoutsideparameters,suchastheheatcoursepower.
