Zusammenfassung:The present invention relates to a centrifugal compressor comprising: an impeller which is connected to a rotary shaft and has a plurality of blades; a scroll which rotatably supports the rotary shaft; a diffuser plate which is coupled to the inner space of the scroll, is open at the center thereof so as to allow the impeller to be inserted therein, and has a plurality of first vanes spaced apart from each other in the circumferential direction; and a shroud which is coupled to the scroll while being spaced apart from the diffusor plate and has a plurality of second vanes at the surface thereof opposite to the diffusor plate, the second vanes not overlapping the first vanes, wherein when the shroud is coupled to the scroll, two delivery flow channels are formed by a second vane which lies between two adjacent first vanes. La présente invention concerne un compresseur centrifuge comprenant : une roue à aubes qui est reliée à un arbre rotatif et possède une pluralité d'aubes ; une volute qui porte de manière rotative l'arbre rotatif ; une plaque diffusante qui est couplée à l'espace interne de la volute, est ouverte au niveau de son centre de façon à permettre à la roue à aubes d'être insérée dans celle-ci, et possède une pluralité de premières ailettes espacées les unes des autres dans la direction circonférentielle ; et une enveloppe qui est couplée à la volute tout en étant espacée de la plaque diffusante et possède une pluralité de secondes ailettes au niveau de sa surface opposée à la plaque diffusante, les secondes ailettes ne chevauchant pas les premières ailettes, dans lequel lorsque l'enveloppe est couplée à la volute, deux canaux d'écoulement de distribution sont formés par une seconde ailette qui se situe entre deux premières ailettes adjacentes. 본 발명은 원심 압축기에 관한 것으로서, 회전축에 연결되고 복수 개의 블레이드를 구비하는 임펠러, 상기 회전축을 회전 가능하게 지지하는 스크롤, 상기 스크롤의 내부 공간에 결합되되, 임펠러가 삽입될 수 있도록 중심부가 개방되고 원주 방향을 따라 이격 배치되는 복수 개의 제1 베인들을 구비하는 디퓨저 플레이트 및 상기 디퓨저 플레이트와 이격된 상태로 배치되어 스크롤에 결합되되, 디퓨저 플레이트와 마주보는 면에는 제1 베인과 중첩되지 않도록 배치된 복수 개의 제2 베인들이 구비되는 쉬라우드를 포함하고, 상기 쉬라우드가 스크롤에 결합될 때, 서로 인접한 두 개의 제1 베인들 사이에 위치하게 되는 제2 베인에 의해 두 개의 전달유로가 형성되는 원심 압축기에 관한 것이다.
