AXIAL FAN FOR VEHICLE

Title:

AXIAL FAN FOR VEHICLE

Document Type and Number:

WIPO Patent Application WO/2002/063172

Kind Code:

A1

Abstract:

An axial fan for vehicle, wherein the leading edge parts (212b) of blades (212) are formed so as to be shifted from a shaft end face (211a) to an air flow upper stream side as viewed from the direction orthogonal to the axial direction of a boss part (211), and the root sides of the blades (212) are joined to the shaft end face (211a) through smooth curved surfaces (213), whereby, since air is allowed to circulate from the shaft end face (211a) side to the root sides of the blades (212), a resistance between blade surfaces and air at the root sides of the blades (212) is reduced by the air flowing from the shaft end face (211a) side to the root sides of the blades (212) to suppress the stalling of the blades (212) at the root side and, since the air forward of the boss part (211) can be led effectively outward (to blades (212)), the lowering of the air discharge rate and fan efficiency of a blower (200) can be suppressed.
