BLOWER MODULE, ITS MANUFACTURING METHOD, AND ELECTRONIC APPARATUS WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a blower module which is low-cost, low-noise and has a high airflow volume supplying capacity without increasing its outside dimension such as a height and a width of a fan.

SOLUTION: The blower module includes a housing with an annular wall at a position spaced from the distal end of fan blades, spokes for joining a rotary driving unit arranged at the center of the fan and the housing together. A ring is arranged at a sucking side of the fan so arranged that a spoke side becomes the sucking side and is fixed to the spokes. As a result, the blower module can be realized in which a loss due to secondary flows and turbulent-flow noises can be reduced without increasing the outside dimension.
