Abstract
Provided is a turbo compressor including a compressed gas inlet through which a gas is sucked in, an impeller for compressing the gas introduced through the compressed gas inlet, a compressed gas outlet through which the gas compressed by the impeller is discharged to the outside, a compression unit including a compressed gas channel connected from the compressed gas inlet to the compressed gas outlet, a motor including a rotating shaft having an end coupled to the impeller, to rotate the impeller, a housing including a motor accommodation space for accommodating the motor, a cooling air channel provided to pass through the motor accommodation space and formed to circulate a cooling gas accommodated therein, a cooling water channel formed to circulate a cooling liquid capable of cooling the housing, and thrust bearings disposed at an end of the rotating shaft, wherein the cooling water channel includes bearing cooling water channels disposed within a predetermined distance from the thrust bearings to cool the thrust bearings. According to the present invention, the thrust bearings supporting the rotating shaft and the cooling gas accommodated in front air channels adjacent to the bearing cooling water channels may be very rapidly cooled.
