High-speed wind-gathering booster fan

Abstract

A high-speed wind-gathering booster fan is provided. The high-speed wind-gathering booster fan includes a housing. An air duct is arranged inside the housing. A motor base is arranged at an axis of the air duct. Part of a circumferential wall surface of the motor base extends radially outward to form guide vanes. The air guide vane includes a parallel part and a torsional wind cutting part. The parallel part is close to the side of an air outlet. The parallel part is in parallel with an axis of an air outlet. The torsional wind cutting part is close to the side of an air inlet. The torsional wind cutting part is deviated from a plane where the parallel part is. An extension surface of the torsional wind cutting part is axially intersected with a wind-deflecting fan blade set.
