| description | The invention relates to an air duct assembly. The air duct assembly comprises a bottom surface, a plurality of cross beams and a plurality of longitudinal beams, wherein two cross beams and two longitudinal beams in the plurality of cross beams and longitudinal beams are arranged at the periphery of the bottom surface in a surrounding manner to form a cavity structure with an open top surface; the plurality of cross beams are fixed on the bottom surface to define the cavity structure into one or more mutually independent air duct structures; at least one longitudinal beam is further fixed tothe cross beam, and the top face of the cavity structure is divided into a plurality of bearing installation areas. An electronic device of roof converter equipment is installed in the bearing installation area of the air duct assembly, a vertical distance of the air duct height is formed between the electronic device and a vehicle body of the rail transit vehicle, and the operation safety of theelectronic device under th |
