1. An air compressor for a vehicle, comprising:
a first compression unit including a front housing having a front inlet into which air to be compressed is introduced and a front outlet from which compressed air is discharged, and a front impeller positioned in the front housing;
a second compression unit including a rear housing having a rear inlet which is connected to the front outlet of the first compression unit through a connection pipe, and into which air passing through the first compression unit is introduced and a rear outlet from which compressed air is discharged, and a rear impeller positioned in the rear housing;
a driving unit having the front housing and the rear housing respectively positioned on the front and rear thereof, and including a motor housing having a cooling water flowing part in which cooling water flows, a stator coupled to an inner peripheral surface of the motor housing, a rotor rotated in the stator and a rotor disk integrally formed with the rotor to drive the front impeller and the rear impeller; and
a cooling unit into which a portion of compressed air compressed by the first compression unit and flowing through the connection pipe is introduced, exchanges heat with the cooling water to cool the driving unit.
