AI Technical Summary

Benefits of technology

The patent describes a blower apparatus that uses flat plates instead of blades, which results in improved air blowing efficiency and reduced noise. The flat plates are easily positioned using a special technique, allowing for quick assembly and achieving desired air blowing performance. The technical effects of the patent include improved air blowing efficiency, reduced noise, and improved assembly performance.

Problems solved by technology

Accordingly, a reduction in the thickness of the blower apparatus, which involves a reduction in the axial dimension of the impeller, will result in a failure to secure sufficient air blowing efficiency.

Abstract

This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet arranged to pass through a portion of the housing in an axial direction above the air blowing portion, and an air outlet arranged to face in a radial direction radially outside of the air blowing portion. One of the flat plates includes a projecting portion arranged to project upward and / or downward, and another one of the flat plates includes an opposing portion arranged to be circumferentially opposed to the projecting portion. Relative circumferential positions of the flat plates can be easily fixed by the opposing portion.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a blower apparatus.2. Description of the Related Art[0002]A centrifugal blower apparatus which generates an air flow traveling radially outward by rotating an impeller including a plurality of blades is known. A known blower apparatus including an impeller is described in, for example, JP-A 2008-88985.[0003]In the blower apparatus described in JP-A 2008-88985, a plurality of blades referred to as fan blades push surrounding gas to generate air flows traveling radially outward.SUMMARY OF THE INVENTION[0004]In recent years, there has still been a demand for reductions in the size and thickness of electronic devices. Accordingly, there has also been a demand for a reduction in the thickness of blower apparatuses used to cool the interiors of the electronic devices.[0005]Here, in the case where an impeller is used to generate air flows, as in the blower apparatus described in JP-A 2008-88985, air ...
