The invention discloses an air duct for a vehicle air conditioner, the vehicle air conditioner and a motor vehicle. The air duct for a vehicle air conditioner comprises an air duct body and a silencing structure formed on the air duct body. The silencing structure comprises a perforated pipe section serving as a part of the air duct body; a plurality of through holes formed in the pipe wall of theperforated pipe section, and an outer wall arranged corresponding to the perforated pipe section. The outer wall is spaced from the perforated pipe section, and the perforated pipe section is surrounded by the outer wall from the outer side of the perforated pipe section, so that the outer wall and the perforated pipe section define a resonant cavity. According to the air duct for a vehicle air conditioner, aerodynamic noise, especially medium-high frequency noise, generated by air flowing can be greatly reduced, and the riding comfort of an automobile can be improved.
