ABSTRACT:
A turbo compressor comprising a driving motor, an impeller to be rotated by the driving motor, a second gas suction part through which gas is introduced into the impeller, and a discharger through which the gas is discharged from the impeller, the turbo compressor comprises a shroud provided between the gas suction part and the gas discharger and spaced from a blade of the impeller; and a plurality of channels provided on the shroud and inclined toward the gas discharger along a rotating direction of the impeller. With this configuration, the present invention provides a turbo compressor in which compression efficiency is increased by eliminating a backflow and a leakage flow.
