CROSS-FLOW FAN
Document Type and Number:
WIPO Patent Application WO/2014/038467
Kind Code:
A1
Abstract:
A cross-flow fan is configured so that flow path loss caused by an intermediate plate or the like is reduced without reducing the strength of the cross-flow fan. Blades (40) extend in the longitudinal direction from a disk-like or circular ring-like support plate. The ring section (61) of an auxiliary ring (60) is located at the intermediate portion of the blades (40) in the longitudinal direction at a position on the outside of the outer ends (40a) of the blades (40). The connection sections (62) of the auxiliary ring (60) are each extended from the ring section (61) to a position between adjacent blades of the blades (40) and are joined to the blades (40) at the positions between the adjacent blades. Cutouts (40g) are formed in the outer ends (40a) of the blades (40).
