[0035] The composite air duct 1 is double-layered insulated by the heat-insulating foam and phenolic foam layers in the interlayer, which can effectively reduce the conduction of heat, so that the thermal insulation effect is very good. The protective layer can improve the stability of the air duct surface and reduce chemical changes. The anti-corrosion layer set on the surface can reduce the corrosion effect on the air duct surface and has a corrosion-resistant effect.
