Abstract (en)
[origin: US2007237656A1] A fan assembly, such as a rotary axial fan assembly, is disclosed with a shroud that is adapted to be mounted proximate to a heat exchanger. The shroud is sized for conveying a flow of fluid through the heat exchanger and the shroud. A stator fan blade extends inward from the shroud for supporting a hub generally central within the shroud. A motor stator is encapsulated within the hub for receiving a fan rotor and fan blades for forcing the flow of fluid through the heat exchanger and the shroud. The hub may be formed from a thermally conductive material for transferring heat from the motor stator into the flow of fluid for dissipating the heat.
