Title: TURBO COMPRESSOR HAVING SEPARATE COOLING AIR CHANNEL
Abstract:
The present invention relates to a turbo compressor and more particularly, to a turbo compressor for compressing a gas such as air and supplying the same to the outside, the turbo compressor comprising: a compressed gas suction opening through which the gas is suctioned; an impeller for compressing the gas introduced through the compressed gas suction opening; a compressed gas discharge opening through which the gas compressed by the impeller is discharged to the outside; a compression unit having a compressed gas channel extending from the compressed gas suction opening to the compressed gas discharge opening; a motor having a rotating shaft, the front end portion of which is coupled to the impeller, in order to rotate the impeller; a housing having a motor containing space for containing the motor; and a cooling gas channel provided to extend through the motor containing space and formed such that a cooling gas contained therein can circulate, wherein the compressed gas channel is spatially separated from the cooling gas channel such that the gas inside the compressed gas channel cannot penetrate into the cooling gas channel. The present invention is advantageous in that the motor can be efficiently cooled with no compression loss occurring to the compression unit.
