TLDR
In this paper, a compact centrifugal fan that draws air in past the impeller hub, which encloses a motor and which spins about a central axis, and then urges the air through a bend in the fluid passageway.Abstract:
A compact centrifugal fan that draws air in past the impeller hub, which encloses a motor and which spins about a central axis, and then urges the air through a bend in the fluid passageway. As the air passes through the annular inlet channel about the impeller hub, it flows in a forward axial direction. The air passes through the bend in the fluid passageway, as the air is being swept around the hub by the blades of the impeller. After the air passes through the bend, it has a reverse axial flow component, in addition to a circumferential flow component. Air having a forward axial flow component passes by the portion of an impeller blade that is closest to the impeller hub, and air having a reverse axial flow component passes the portion of a blade that is furthest from the impeller hub.read more

Patent
Fan assembly having an air directing member to cool a motor
Peter A. Kershaw,Marek Horski +1 more
TL;DR: In this article, a motor driven fan assembly is described, where a hub has a plurality of fan blades which extend radially outwardly therefrom and is fixed to an air cooled brushless motor for rotation, such that when the hub is rotatably driven by the motor, the fan blades create an atmospheric pressure differential defined by a higher pressure region downstream of the fan and a lower pressure region upstream of the blades.
Patent
Automotive air conditioning fan assembly
TL;DR: In this article, the authors proposed a fan housing having a wall portion specially shaped so as to provide the air confinement function that the missing section of the fan hub cannot, and demonstrated that the wall portion of a fan can be used for air conditioning.
Patent
Hand-guided machine tool comprising a radial blower
TL;DR: A hand-guidable electric machine tool has a casing having an air guide duct, a tool part, a motor for driving the tool part and a radial blower for cooling the motor as discussed by the authors.
Patent
Fan with a filter
TL;DR: In this article, a fan assembly for creating an air current is described, the fan assembly having a nozzle, a system for creating air flow through the nozzle and a filter for removing particulates from the air flow, the nozzle having an interior passage, a mouth for receiving the air stream from the interior passage and a Coanda surface located adjacent the mouth and over which the mouth is arranged to direct the flow, wherein the fan provides an arrangement producing an air flow and a flow of cooling air created without requiring a bladed fan.

Self-priming centrifugal pump
TL;DR: In this paper, the authors present a self-priming self-pumping method for the use of centrifugal pumps of the self-prime type, which has a wider application than this particular type.
Patent
Single-stage, multiple outlet centrifugal blower
TL;DR: The rotatable impeller of a single-stage centrifugal blower is housed in a casing one side of which comprises a spiral plenum having an opening which extends along a predetermined limited portion of the perimeter of the impeller and the other side includes a port which is displaced from the opening of the plenum so that it is out of register with that opening.
Patent
Air foil fan
Abstract: A multibladed rotatable fan, for cooling motors and the like within a confined housing, having air foil blades designed to produce maximum air flow axially within the limited crosssectional area of the housing and discharge the air at an angle from the housing while maintaining a minimum noise level and reduced turbulence at high speeds within the housing.
