測定装置。[Scope of Claim for Utility Model Registration] (1) A wind tunnel that has openings at both ends, one of which is attached to the outlet of a fan to collect all the swept air, and a wind tunnel that is attached to the other opening of the wind tunnel and has a cross-sectional shape. Consists of a rectifier tube that is the same in the longitudinal direction and has a cross-sectional area smaller than the area of the fan outlet, and a wind speed measuring device that measures the wind speed of the airflow discharged from the rectifier tube at a position near the outlet of the rectifier tube. A fan airflow measuring device characterized by: (2) Following the wide opening, there is a reduced-diameter pipe section whose cross-sectional area decreases in the longitudinal direction, followed by a rectifying pipe section whose cross-sectional shape is uniform, so that the wide opening can be attached to the fan's outlet. A wind tunnel and
1. An airflow measuring device for a fan, comprising: a wind speed measuring device that measures the wind speed of an air flow discharged from a wind tunnel at a position near the outlet of a rectifying pipe section of the wind tunnel.
