Beschreibung
Zusammenfassung:	The present invention relates to a muffler for a vehicle air conditioner and, more specifically, to a muffler for a vehicle air conditioner, wherein a diameter reducing part is additionally formed in a muffler applied with a Helmholtz resonance structure to reduce noise in a target frequency band through the Helmholtz resonance structure as well as noise in a different frequency band, namely in a broadband through the diameter reducing part. Therefore, the muffler for a vehicle air conditioner reduces a production cost and has a reduced weight without an increase in the number of mufflers. 본 발명은 차량 공조장치용 소음기에 관한 것으로써, 더욱 상세하게는 헬름홀쯔 공명 구조를 적용한 소음기에서 축관부를 추가 형성함으로써, 헬름홀쯔 공명구조를 통한 목표 주파수 대역에 대한 소음 감쇄 뿐만 아니라 상기 축관부 구성을 통한 다른 주파수 대역 다시말해 넓은 주파수 대역(Broadband 대역)에 대한 소음까지 감쇄할 수 있고, 이로인해 소음기의 개수를 늘리지 않아도 되므로 원가 및 중량도 줄일 수 있는 차량 공조장치용 소음기에 관한 것이다.
