    Abstract: The present invention provides an axial fan including a hub adapted for rotation about a central axis and a plurality of blades extending radially outwardly from the hub and arranged about the central axis. Each of the blades includes a root, a tip, a leading edge between the root and the tip, and a trailing edge between the root and the tip. Each of the blades defines a blade radius between the blade tips and the central axis. Each of the blades defines a decreasing skew angle within the outer 20% of the blade radius. The ratio of blade pitch to average blade pitch increases from a lowest value to a highest value within the outer 20% of the blade radius. The highest value is about 30% to about 75% greater than the lowest value.

    Abstract: An appliance, such as a fan, to which it is possible to fit an accessory by using fixing devices, which accessory (17) can be mounted on the appliance so as to change the mode of operation of the appliance. The appliance of the invention is so designed that, by mounting a small accessory, a standard model, e.g. an axial-flow fan, can be converted e.g. into three other generally known fan versions. These are the so-called guide vane, mixed flow and radial flow versions. Traditionally, these are completely separate fans, each requiring separate designing, component manufacture and assembly. In the case of the fan of the invention, these can be achieved with a minimum amount of work. The frame, motor structure and electronics of the fan as well as the frame of the impeller are the same in all these models.

    Abstract: An efficient axial flow fan (2) comprises a central hub (6), a plurality of blades (8), and a band (9), and is designed to operate in a shroud (4) and induce flow through one or more heat exchangers (5) - in an automotive engine cooling assembly, for example. The fan blades (8) have a radial distribution of pitch ratio that provides high efficiency and low noise in the non-uniform flow field created by the heat exchanger(s)(5) and shroud (4). The blade (8) has either no sweep, or is swept backward (i.e. opposite the direction of rotation) in the region between the radial location r/R=0.70 and the tip (r/R-1.00). The blade pitch ratio increases from the radial location r/R=0.85 to a radial location between r/R=0.90 and r/R=0.975, and then decreases to the blade trip.

    Abstract: A plastic fan comprising two injection molded parts (20, 60), each of which includes its own hub (22, 62) and a set of blades (24, 64) extending outwardly from the hub to a band (26, 66). The two parts are co-operatively sized and shaped to be assembled into a single operable fan (80) having: 1) a hub comprising the hubs of each of the component parts; 2) the blades of the component parts; and 3) a circumferential band (86) comprising the bands of the component parts. The fan blade separation on each of the fan parts is relatively large, permitting separate injection molding of each part. The resulting fan may be designed to have far greater blade number and blade solidity than would be possible for a fan that is injection molded by standard techniques.
