CROSS-FLOW FAN
Document Type and Number:
WIPO Patent Application WO/2023/157289
Kind Code:
A1
Abstract:
Provided is a cross-flow fan with which stall at the end of an impeller is minimized and stall resistance can be improved. To achieve this purpose, a cross-flow fan (100) comprises an impeller (110) comprising a plurality of support members and a plurality of blades provided between adjacent support members, a motor (150) provided at one end of a rotating shaft of the impeller, a stabilizer (220) disposed along the rotation axis direction with a gap from the outer periphery of the impeller, and a protrusion (221) provided protruding toward the impeller side on an impeller-facing surface of the stabilizer and disposed along the rotation axis direction. The motor-side end of the protrusion in the rotation axis direction is disposed farther along the downstream side in the direction of impeller rotation than the center of the protrusion in the rotation axis direction.
