Novel counter-rotating axial flow local fan of motor supporting and heat dissipation structure

The utility model relates to a contra-rotating axial flow local ventilator of a novel motor supporting and radiating structure, which comprises a ventilator main machine, a current collector and a rear silencer, the current collector and the rear silencer are arranged at two ends of the ventilator main machine, and a front flow guide part and a rear flow guide part are respectively arranged in the middle of the current collector and the middle of the rear silencer. A front air inlet hole and a rear air inlet hole are respectively formed in the center of the front flow guide piece and the center of the rear flow guide piece in the axial direction of the ventilator, and the front air inlet hole and the rear air inlet hole are respectively formed in the center of the front flow guide piece and the center of the rear flow guide piece in the axial direction of the ventilator. The motor is prevented from being damaged; the arrangement mode of supporting ribs in the prior art is changed, the rigidity and torsional s
