NOVELTY - The utility model relates to the power module radiating technology field, especially relates to a power module radiating structure, comprising a graphene radiating film layer, a power module; DBC layer and a radiator; the graphene radiating film layer is attached at the bottom of the power module; the DBC layer is installed on the bottom plate of the power module; the radiator is installed below the graphene radiating film layer. The utility model is attached graphene radiating film layer at the bottom of the power module, reducing thermal resistance of the thermal interface material, improving radiating efficiency and radiating effect; In addition, graphene radiating film layer forms arc structure matched with the power module radian by means of lamination, can be completely jointed with the bottom of the power module and the radiator, enhancing the radiating effect.
