NOVELTY - The utility model claims a heating heat exchange tube with far infrared function, the heating heat exchange tube from inside to outside in turn comprises a graphene composite layer, EVOH layer and far infrared outer layer; the graphene composite layer is surrounded into a hollow tube; the EVOH layer is respectively used maleic anhydride and graphene composite layer; the far infrared layer is adhered by co-extrusion. The utility model has high heat exchange efficiency, good oxygen resistance and mechanical property, and it can radiate far infrared ray.
