| description | The utility model discloses a centrifugal ventilator for cooling an auxiliary converter of a motor train unit vehicle, which comprises an impeller, an engine base middle mounting ring, a motor, a support frame component, a support rod, a front end mounting plate and an air inlet duct, and the air inlet duct is partially inserted into the impeller to form partial overlapping and form a non-contact transition structure. The supporting frame assembly, the supporting rod and the front end mounting plate form a frame type cavity structure, and the impeller is of a centrifugal structure. The utility model solves the problems that the axial space size of the ventilator in the prior art is limited; the fan has the advantages of being small in axial space size, good in vibration control and compact in structure, impeller airflow can flow out around the radial direction, the cooling speed is increased, and the fan is specially developed for being suitable for installation occasions where axial space of a ventilator for |
