There is provided a centrifugal fan including an upper casing which has an air suction opening, a lower casing, and an impeller which is disposed between the upper casing and the lower casing. The impeller includes an upper shroud which is provided on an upper casing side, and a plurality of blades which are arranged along a circumference direction below the upper shroud, and is rotatable around a rotary shaft. The upper casing and the lower casing configure an open-type casing. A surface of the upper shroud facing the upper casing includes a first portion which becomes closer to the lower casing as separating further from the rotary shaft. A surface of the upper casing facing the upper shroud includes a second portion which faces the first portion of the upper shroud and becomes closer to the lower casing as separating further from the rotary shaft.

An impeller includes: a main plate; a shroud; and a plurality of blades provided between the main plate and the shroud and arranged circumferentially; wherein the impeller is configured to rotated about a rotation axis; wherein the plurality of blades include a pressure surface and a negative pressure surface; and the pressure surface has a shape, in which at least three types of circular arcs are connected, as viewed from a rotation axial direction. A centrifugal fan includes the above-described impeller; and three or more pillars, wherein an interval between one adjacent pillars of the three or more pillars is different from an interval between the other adjacent pillars of the three or more pillars.
摘要:
A centrifugal fan is provided. The centrifugal fan is configured such that an impeller having a plurality of blades along a circumferential direction and disposed between a disk-shaped main plate and an annular shroud is housed in a casing configured by an upper casing and a lower casing, and that an air suctioned from a suction opening is discharged outward in a radial direction of the impeller by a centrifugal force due to a rotation of the impeller. The shroud has a curved surface formed from an outer edge portion toward a center thereof. The shroud has a plurality of protrusions which are formed on the surface of the shroud such that a gap is formed between each of the protrusion portions and the upper casing.

A centrifugal fan is provided. The centrifugal fan is configured such that an impeller having plural blades disposed between a disk-shaped main plate and an annular shroud along a circumferential direction is accommodated 5 in a casing, and that an air suctioned from a suction opening is discharged outward in a radial direction of the impeller by a centrifugal force due to a rotation of the impeller, and thereby discharging the air from the casing. The casing includes an upper plate, a lower plate, and plural supporting struts interposed between the upper plate and the lower plate, and 10 lateral sides of the casing have only the supporting struts to form a discharge opening.
