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.
本申请公开了一种用于车辆空调的风道、车辆空调和机动车辆。该用于车辆空调的风道包括:风道主体和形成在所述风道主体上的消声结构。所述消声结构包括作为所述风道主体的一部分的穿孔管段,在所述穿孔管段的管壁上构造有多个贯穿孔,对应于所述穿孔管段设置的外壁,所述外壁与所述穿孔管段间隔开并且从所述穿孔管段的外侧包围了所述穿孔管段,以使得所述外壁和穿孔管段围成共振空腔。本申请的用于车辆空调的风道可极大地减轻空气流动产生的气动噪声,特别是中高频噪声,这有助于改善汽车的乘坐舒适性。
