An apparatus for manipulating a substance, the apparatus having a blade having: a fin hub associated with a fin formed by a sinusoidal outer edge and an inner surface extending from the sinusoidal edge to a center of the fin, the fin hub being associated with a portion of the sinusoidal outer edge of the fin, such that to cause the fin hub and the fin to rotate simultaneously about a rotational axis that is coaxial with the fin hub; wherein, said substance is simultaneously pulled in via two opposing vortexes that are coaxial with the rotational axis, toward said portion of the sinusoidal outer edge of the fin, and said substance is also simultaneously push out 360 degrees around and away from the rotational axis. The blade is configured to axially intake and radially output a substance, such as air, for rapid, efficient mixing of said substance.

Particular embodiments described herein provide for an electronic device that can be configured to include a fan where the fan blades are decoupled from the center shaft. The fan can include a center shaft, a motor coil support, motor coils coupled to the motor coil support, a rotator coupled to the center shaft, and fan blades coupled to the rotator, where rotation of the fan blades is decoupled from the center shaft by the rotator. A blade support can be coupled to the rotator, where the blade support couples the fan blades to the rotator and magnets can be coupled to the blade support. In an example, the rotator can include an inner, an outer race, and bearings.

An apparatus for a centrifugal pump includes an impeller. The impeller has a rear shroud on which blades are arranged. The impeller has a hybrid component structure. The hybrid structure includes at least one generative component and at least one conventional component. At least one of the generative component and the conventional component is subdivided into at least two segments.

An air blower includes: a panel (3); a frame member (5) arranged to surround the panel (3) and having a blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g) of air formed therein; and a fan (11a, 11b, 11c, 11d, 11e, 11f, 30) that sends air to the blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g). The frame member (5) produces airflows that are blown out from at least three directions and collide with each other, thereby producing an air current going forward to the panel (3).

A blower according to an embodiment of the present disclosure includes: a case; a fan; and a diffuser disposed downstream of the fan and guiding air, discharged from the fan, toward the discharge ports, wherein the diffuser includes: an outer wall; an inner wall spaced apart inwardly from the outer wall so that an air passage is formed therebetween; and a plurality of vanes extending radially between the outer wall and the inner wall and dividing the air passage into a plurality of unit passages, wherein the outer wall and the inner wall are formed to have areas with different radial separation distances D between the outer wall and the inner wall, such that in an area of the air passage of the diffuser in which air is discharged to a portion having a high flow resistance in the blower, the radial separation distance D increases to widen the air passage S, thereby compensating for the asymmetry of the passage inside the blower, allowing a uniform volume of air to reach the entire area of the discharge ports, and improving the performance of the blower.
