FAN AND AIR CONDITIONER USING SAME

摘要

This fan has: a crossflow fan; a stabilizer disposed facing the crossflow fan; a rear guider that forms an airflow pathway with respect to the stabilizer; and a side wall disposed in a direction perpendicular to the rotational axis of the crossflow fan. A protrusion is formed protruding to the stabilizer side compared to the central section of the rear guider across a predetermined range of the axial direction with respect to the rotational axis of the crossflow fan from the tip at the output side of the rear guider. As a result, it is possible to secure to the fullest extent an airflow pathway at the central section at which the flow is stable and the air speed is fast, and meanwhile it is possible to stabilize flow and increase static pressure in the vicinity of the side wall at which the flow is unstable and the air speed is slow.
