Abstract
A transverse fan in which a plurality of blades are disposed between disk- or ring-shaped end plates in a circumferential arrangement at fixed mounting pitches in a ring-shaped configuration. Partitions plates are disposed at intermediate portions in the longitudinal direction of the blades such that each of the blades is inclined at fixed angles with respect to a fan axis and mounted at unequal pitches. The transverse fan includes a plurality of multi-bladed impeller units disposed between the disk-shaped end plates. Each of the multi-bladed impeller units has one disk-shaped partition plate having one surface on which a plurality of blades are integrally disposed along a circumferential direction thereof at unequal pitches and inclined at predetermined angles so as to extend along the axial direction of the transverse fan. A plurality of the multi-bladed impeller units are integrally stacked coaxially with each other to form the transverse-fan. The multi-bladed impeller units are integrally stacked one by one in an arrangement such that the units are displaced at predetermined angles with respect to each other around the fan axis.
