The invention discloses a parallel combined type train air conditioner air duct silencer based on an inner inserting pipe structure. The parallel combined type train air conditioner air duct silencer comprises a base plate, an air duct in the middle area in the base plate and two combined type silencers symmetrically arranged on the two sides of the air duct along the axis of the air duct. The combined type silencer is used for conducting broadband noise reduction on noise in the air duct. According to the technical scheme, the problem that the silencing frequency band of a single silencer is narrow can be solved, and the silencer is suitable for comprehensive treatment of train air conditioner air duct noise.

    本发明公开了一种基于内插管结构的并联复合式列车空调风道消声器,包括基板,基板内部的中间区域为风道,沿风道的轴线对称布设在风道两侧的两个复合式消声器;所述复合式消声器用于对风道中的噪声进行宽频带降噪。本发明的技术方案能够解决单个消声器消声频带狭窄的问题,适用于列车空调风道噪声的综合治理。
