The present invention relates to a direct drive type dual turbo blower cooling structure and, more particularly, to a direct drive type dual turbo blower cooling structure in which a plurality of hole portions for cooling a stator and a plurality of hole portions for cooling a coil portion, a bearing housing, and a rotor are formed along the inner diameter of a motor casing; impellers are disposed on both sides thereof, such that a flow rate is doubled; and an air cooling system capable of achieving thermal balance through the plurality of hole portions is implemented at the time of operation of a cooling fan which provides an air cooling system instead of a conventional water cooling system. As such, it is possible to simplify the mechanical structure and reduce manufacturing time and costs because the pump, heat exchanger, water tank, pipes, etc. required for a water cooling system are unnecessary. |
