ABSTRACT:
A housing for a propeller or axial flow fan. The housing comprises an orifice portion, a stator element portion and a motor mount portion, preferably made in a single piece by casting in metal. The single piece construction makes possible the positioning of the axis of rotation of the fan to be used with the housing precisely coincident with the axis of the orifice and thus permits very small fan blade tip to orifice wall clearances to be attained, increasing the efficiency of the fan assembly and reducing its radiated noise. The inlet of the orifice is elliptical to promote attached flow. In a preferred embodiment, the motor mount portion of the housing also is configured to serve as the motor shaft end cap of the electric motor used to drive the fan. The number of parts in a complete fan, housing and motor unit in such a configuration is reduced to two, the fan and the motor, reducing the time required to assemble and install the unit.
