Abstract
PURPOSE: To obtain large air-blowing capacity with low noise by setting the blowoff angels of blades at 45° with a range of ±10° and decreasing their chord length as they near the suction side.
CONSTITUTION: The device is composed of a disc 1 and blades 2 that are arranged with fixed intervals on its front-side rim. Air is sucked from the front side to the axial direction and blowed to the periphery side. The blowoff angle α of a blade 2 is set to be 45°±10° against the tangent a. Also, the inside part of a blade 2 is inclined so that its chord height 1 becomes shorter as it nears the suction side 4, enlarging the suction diameter d. This structure compensates the decrease of the suction area due to the motor fixing part
