【Abstract】To addresstherequirements forheat disipationand temperature uniformityof lithium-ionbatteries within confined spaces，this paper propose a heat dissipation structure for power batteries based on heat pipes，which includes aluminumplatesandheatpipes.Takinga4OA·hlithium-ionbattryastheresearchsubject，abatteryheat generationmodel is established.Numericalsimulationmethodsareadoptedtoexploretheimpactofdiferent workingfluidsandnumbersofheat pipes onthetemperatureof powerbateries.Theresults indicate that when the numberof heat pipes is6，both the heat pipe cooling structures using deionized water and Fe ∂304 nanofluid as working fluids exhibit good heat dissipation performance，with the heat pipe using Fe3O4 nanofluid demonstrating beter cooling effects on the battery module.When the number of heat pipes is increasedto9，itisfoundthatunderdischargeratesof1C，2C，and3C，themaximumtemperaturesof thebaterymodule decreaseby0.5℃，1.77℃ and 2.24∘C respectively.
