  • Cooling fan vane assembly for a resistor grid
    Patent number: 10081250
    Abstract: A cooling fan vane assembly for a resistor grid may include a duct having a substantially round inlet opening, a substantially rectangular outlet opening, and a side wall extending between the inlet opening and the outlet opening shaped to transition from a substantially round shape to a substantially rectangular shape; the inlet opening including a plurality of radially extending turning vanes; and a frustoconical vane positioned in the duct adjacent a downstream side of the plurality of radially extending vanes.
    Type: Grant
    Filed: December 15, 2014
    Date of Patent: September 25, 2018
    Assignee: DAYTON-PHOENIX GROUP, INC.
    Inventors: Justin P. Widmer, Gabriel E. Widmer
  • Braking grid cooling system
    Patent number: 9815374
    Abstract: A braking grid cooling system may include a fan having a hub supporting a rotor and at least partially enclosing a stator, and a plurality of fan blades connected to and projecting radially from the hub; and a dynamic braking grid receiving the fan in a nested relation such that a combined height of the grid and the fan is less than a sum of a height of the grid and a height of the fan.
