Abstract

792,369. Axial-flow fans. AIRSCREW CO. & JICWOOD, Ltd. Jan. 24, 1956 [Jan. 24, 1955], No. 2037/55. Class 110 (1). In an axial-flow fan of the kind in which the impeller blades operate within a cylindrical casing from which extends an air duct, the impeller projects an air stream having an outward component of velocity, and vaned guiding means in the path downstream of the air stream gradually change the direction of the air stream so that it obtains an inward component of velocity within the air duct. The fan impeller c is followed by guide vanes f extending from a cylindrical duct h to a generally conical fairing e. The vanes f are curved and are inclined in the direction of rotation from their outer to their inner ends. The upstream edges k of the vanes fare nearly vertical and the downstream edges i meet the fairing e at an acute angle. The fairing e is of smaller diameter than the impeller hub, to permit the inward component of velocity to be obtained within the duct h; it may be replaced by a cylindrical tube substantially smaller in diameter than the impeller hub. The guide vanes may be embodied in a unit disposed downstream of a separate conventional fan. The guide vanes and the fairing may rotate.
