Problems solved by technology

Therefore, depending on the arrangement position of the axial flow blower, there are cases where the lead wire cannot be pulled out to the suction port side (for example, when it is desired to pull the lead wire out to the discharge port side in the axial direction of the axial flow blower), and the lead wire may becomes complicated by wrapping around
In addition, in the conventional axial flow blower, problems such as the lead wire pulled out to the suction inlet side contacting the impeller, and the lead wire wound back to the suction inlet side encountering the wind caused problems such as increased noise.

Abstract

An axial flow fan provided herein allows for a wide range of selection for placement of the fan and wiring of the lead wires. The axial flow fan includes a first lead wire engaging portion 17 configured to be engaged with a plurality of lead wires 15 such that the lead wires are pulled out therefrom into an outer space OS defined between a first flange 21 and a second flange 23 of a fan housing 3, a second lead wire engaging portion 19 configured to be engaged with the plurality of lead wires 15 such that the lead wires, which have been engaged with the first lead wire engaging portion 17 and pulled out therefrom into the outer space OS, are then pulled out toward the other side in the axial direction where the second flange 23 is positioned, and a third lead wire engaging portion 27 configured to be engaged with the plurality of lead wires 15 such that the lead wires, which have been engaged with the first lead wire engaging portion 17 and pulled out therefrom into the outer space OS, are then pulled out in the axial direction toward one side where the first flange 21 is positioned. The third lead wire engaging portion 27 is formed in the first flange 21 at a given distance from the first lead wire engaging portion 17.

Description

Technical field [0001] The present invention relates to an axial blower used for internal cooling of electric equipment and the like. Background technique [0002] Japanese Patent Application Laid-Open No. 2007-309313 (Patent Document 1) discloses an axial blower that includes a first flange located on the discharge port side of the axial direction of the axial flow blower, and a second flange located on the suction port side. A cylindrical fan housing is formed between the two flanges. The first flange is formed with a first lead wire locking portion that locks the plurality of leads into the outer space between the first flange and the second flange, and is formed on the second flange There is a second lead wire locking portion that locks the plurality of lead wires drawn into the external space to the suction port side. [0003] Patent Document 1: Japanese Patent Application Publication No. 2007-309313 ( figure 1 ) [0004] In this conventional axial flow fan, it is comprised s...
