Abstract: Toimprovethetemperaturecontrolreliabilityofspacecraftthermalcontrolsystem,aselfadaptiontemperaturecontrolcoldplatewasdesignedbasedonthevolumechangecharacteristicsoftheparaffinwaxduetothephasechangeasitstemperaturechanged.Thedesignmodeloftheselfadaptiontemperaturecontrolcoldplatewasbuilt,andthethermalnetmodelofthesinglephasefluidloopwiththecoolplatewasgiven.Theperformanceofthecoldplateandthesinglephasefluidloopwasanalyzed.Resultsshowthatthecoldplatedesignedhastheabilityofselfadaptiontemperaturecontrol,anditmaybewidelyusedinthetemperaturecontrolfortheelectronicdevicesatgroundandheatloadsonspacecraft.
