The invention provides a silencing device for a vehicle air conditioner drainage pipe and a vehicle provided with the silencing device, and particularly relates to the field of vehicle air conditioner equipment. The silencing device for the vehicle air conditioner drainage pipe comprises a silencing body and a connecting pipe. A closed silencing cavity is formed in the silencing body; the connecting pipe is arranged in the silencing cavity; the two ends of the connecting pipe extend out of the silencer body, wherein a plurality of partition plates are arranged in the silencing cavity, the multiple partition plates divide the silencing cavity into multiple silencing resonant cavities in the extension direction of the connecting pipe, and the multiple silencing resonant cavities are independent of one another; and at least one opening is formed in the portion, in each silencing resonant cavity, of the connecting pipe, and the openings are opened towards cavity bodies of the silencing resonant cavities. According to the silencing device, coupling of noise with the specific frequency in the silencing resonant cavities and the drainage pipe is achieved, the prominent peak noise intensity in the noise frequency spectrum is effectively reduced, and similar blowing sound noise occurring when the vehicle accelerates is eliminated.

    本发明提供一种用于车辆空调排水管的消音装置和安装该装置的车辆,具体涉及车辆空调设备领域,该用于车辆空调排水管的消音装置包括:消音体和连接管。消音体,其内设置有密闭的消音腔;连接管,其设置在所述消音腔内;且两端伸出至所述消音体外;其中,所述消音腔中设置有多个隔板,所述多个隔板沿所述连接管延伸方向将所述消音腔分为多个消音谐振腔,所述多个消音谐振腔彼此独立;在各个所述消音谐振腔中的连接管上设置有至少一个开口,所述开口朝向所述消音谐振腔的腔体敞开。本发明的消音装置实现了消音谐振腔与排水管中特定频率的噪音的耦合,有效地降低了噪音频谱中突出的峰值噪音强度,消除了车辆在加速时出现的类似吹气声噪音。
