Abstract: Thethermaldesignoflunarexplorationdevicesandinstrumentsdependsonrealinformationofthethermalenvironmentofthelunarsurface.UsingthethermalanalysismoduleinANSYS,andconsideringthatthethermalconductivityofthelunarsoilvarieswithbothdensityandtemperatureandthespecificheatisafunctionoftemperature,alunarsoiltemperaturesolvingmodelwasdeveloped.Andthelunarsurfacetemperaturesatthelatitudeof26°andtheequatorwerethencalculatedrespectively.Thetemperaturedistributionofsuperficiallayersattheequatorwasalsodiscussed.Thegoodagreementofthecomputedresultsandthemeasureddatainlunarsurfacetemperaturesrevealsthatthemodelandtheselectedparametersareapplicableandreliable,besides,thefurthermatchedpredictingresultsandmeasureddatawithasomewhatmodifiedlunarsoilconductivitypartlyshowthefunctionofthemodelincalculatingthelunarsoiltemperature.Todiscussthetemperaturedistributionofsuperficiallayersattheequator,thelunarsoiltemperatureandtheheatfluxprofilesatdifferenttimeswereplotted,andtheeffectsofthelunarinnerheatfluxandtheconductivityofthelunarsoilonthesoiltemperaturewerealsoanalyzed,whichmighttheoreticallysupportthethermaldesignsforlunarexplorationdevicesorinstruments.
