【Abstract】To enhance the heat dissipation performance of automotive power bateries，the coling structure underwent thermaltopologyoptimizationdesignusing thevariabledensitymethod.Initialy，withthe minimumaverage temperatureasthe objective，theinfluenceofdiferentoptimizationparametersonthetopologicalshapeisanalyzed.Subsequentlyamultiobjectiveoptimizationfunctionisutilizedtoobtainthefinalmodel.Basedonengineeingpriorities，theimpactofdifferent weightsontheheatdisipationperformanceof the topologicalstructureandthevariatiopatternsofthetopological structure underdifferentvolumefractionsareanalyzed.Finaly，acomparativeverificationisconductedbetweenthetopologyoptiized coldplateandthetraditionalcoldplate.Theresultsindicatedthatthevalueof thepenaltyfunctionsignificantlyafects the material distribution characteristics.When the filtering radius is reduced to 0.01mm ，afine branching structure can be generated，butitmayleadtosructuraldiscretizationandmanufacturingchallnges.Themultiobjectiveoptimizationesults showedthatthe topology-optimizedcoldplate exhibitsa lower maximum temperatureand pressure dropunder different dischargerates comparedtothe traditionalcold plate，indicatingitssuperiorabilityto manage batery heatdistribution.
