CENTRIFUGAL COMPRESSOR AND WATER-COOLING UNIT EQUIPPED THEREWITH Russian patent published in 2018 - IPC F04D17/10 

FIELD: machine building.

SUBSTANCE: invention discloses a centrifugal compressor and a water cooling unit equipped therewith. Centrifugal compressor comprises: impeller (2), diffuser (3), spiral chamber (8) and an outlet pipe of diffuser (9), diffuser (3), including boost channels (31), air flowing through impeller (2) enters the inlet of boost channel (31), spiral chamber (8) is configured to collect air compressed in diffuser (3), outlet pipe (9) of the diffuser is connected to spiral chamber (8), and the direction of extension of diffuser outlet pipe (9) is tilted downward relative to the horizontal plane. Direction of extension of outlet pipe (9) of the diffuser connected to spiral chamber (8) tilts downward relative to the horizontal plane, so that the noise and loss of the high temperature air stream and the high-pressure air in diffuser outlet pipe (9) discharged from the centrifugal compressor can be reduced due to the bending of the pipe.

EFFECT: noise level can be effectively reduced.
