The invention relates to the technical field of compressor noise reduction, in particular to a multi-stage noise elimination structure of a rotary vane compressor shell of a vehicle air conditioner, a first partition plate is connected with a first inner cavity air channel of the shell, the first partition plate is provided with a first exhaust hole, a first low-frequency resonance noise elimination cavity comprises a supporting boss and a noise elimination cavity body, the supporting boss is connected with the shell, the silencing cavity body is connected with the supporting boss, the expansion tube type silencing cavity comprises an incident sound wave band, a reflected sound wave band and a transmitted sound wave band, the incident sound wave band is connected with the shell, the reflected sound wave band is connected with the incident sound wave band, the transmitted sound wave band is connected with the reflected sound wave band, Heat generated by working of a compressor enters the silencing cavity body through the supporting boss from the first exhaust hole of the first partition plate to eliminate part of noise, then enters an incident sound wave band through the first inner cavity air channel and then enters a reflection sound wave band, and the noise is blocked by the reflection sound wave band; the problem that a primary silencing cavity formed through assembly is poor in aerodynamic noise reduction effect is solved.

    本发明涉及压缩机降噪技术领域,具体涉及车用空调旋叶式压缩机外壳多级消声结构,第一隔板与外壳的第一内腔气道连接,第一隔板具有第一排气孔,第一低频共振消声腔包括支撑凸台和消声腔本体,支撑凸台与外壳连接,消声腔本体与支撑凸台连接,扩张管式消声腔包括入射声波段、反射声波段和透射声波段,入射声波段与外壳连接,反射声波段与入射声波段连接,透射声波段与反射声波段连接,压缩机工作产生的热量从第一隔板的第一排气孔经支撑凸台进入消声腔本体消除部分噪声,然后经第一内腔气道进入入射声波段后进入反射声波段,反射声波段将噪音阻断,解决了通过装配形成的一级消声腔的降低气动噪声的效果差的问题。
