The present invention relates to a direct driven dual turbo blower cooling structure and, more specifically, relates to a direct driven dual turbo blower cooling structure comprising a plurality of hole parts and a coil part for cooling a stator along an inner diameter of a motor casing and a plurality of hole parts for cooling a bearing housing and a rotor. According to the present invention, the direct driven dual turbo blower cooling structure has an effect of doubling the flow by configuring impellers at both sides and does not require a pump, a heat exchanger, a water tank, or piping, which are necessary to a water cooling system, because it incorporates an air cooling system which is able to achieve heat balancing through the multiple hole parts at an operation of a cooling fan, which provides an air cooling system rather than a water cooling system, thus simplifying its mechanical structure and reducing production period and costs. |
