Embodiment Construction

[0032]In the following, embodiments of the present invention will be described with reference to the accompanying drawings.

[0033]FIG. 1 is a perspective view showing an axial fan apparatus according to an embodiment of the present invention. FIG. 2 is a plan view showing the axial fan apparatus of FIG. 1, denoted by reference numeral 10, seen from a back surface side thereof. FIG. 3 is a side view of the axial fan apparatus 10.

[0034]The axial fan apparatus 10 includes a housing 3 and an axial-flow impeller 5. The axial-flow impeller 5 is capable of rotating inside the housing 3. The axial-flow impeller 5 includes a boss unit 6 and a plurality of blades 7. A motor (drive unit; not shown) is built in the boss unit 6. The plurality of blades 7 are provided around the boss unit 6.

[0035]The housing 3 includes an annular sidewall 35. An opening at an upper portion of the sidewall 35 serves as a suction port 3a. Airflows in an axial direction (Z direction) generated by the blades 7 rotatin...

Abstract

An axial fan apparatus including an axial-flow impeller, a drive unit, and a housing. The axial-flow impeller is capable of rotating and includes a plurality of blades inclined with respect to a rotational axis direction. The drive unit rotates the axial-flow impeller. The housing is mounted with the drive unit, and includes a sidewall, and a plurality of slits that circulate gas. The sidewall is provided around the axial-flow impeller. The plurality of slits are provided to the sidewall and inclined with respect to the rotational axis direction in a direction opposed to a direction in which the plurality of blades incline.

Description

RELATED APPLICATION DATA[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 101,558, filed Apr. 11, 2008, the entirety of which is incorporated herein by reference to the extent permitted by law. The present application claims priority to Japanese Patent Application No. 07-107749 filed in the Japanese Patent Office on Apr. 17, 2007, the entirety of which also is incorporated by reference herein to the extent permitted by law.BACKGROUND OF THE INVENTION[0002]The present invention relates to an axial fan apparatus that blows air in an axial-flow direction, a housing that is used for the axial fan apparatus, and an electronic apparatus that is mounted with the axial fan apparatus.[0003]Recently, fans are used to cool down heat generators in most electronic apparatuses such as PCs. Herein, it is necessary to increase flow rate of the fans and to reduce noise generated by the operating fans.[0004]Japanese Patent Application Laid-open No. 2001-003900 (paragraph...
