Document Type and Number:
Japanese Patent JP7400629
Kind Code:
B2
Abstract:
A blower device includes a centrifugal fan that sucks air from one side of the blower device in an axial direction, and an air flow guide disposed between the centrifugal fan and the other side of the blower device in the axial direction. A first air flow from the centrifugal fan is bent toward the other side in the axial direction. A second air flow from the centrifugal fan is bent toward the other side in the axial direction, and then bent inward in the radial direction. A ratio of a pressure loss in the second air flow to a pressure loss in the first air flow before a downstream end of the air flow guide is smaller than a ratio of a pressure loss in the second air flow to a pressure loss in the first air flow before an upstream end of the air flow guide.
