ABSTRACT:
An assembly of a fan and shroud is provided in which a shroud has an inner ring which is substantially cylindrical to guide airflow by surrounding blades, an outer ring which has a diameter greater than that of the inner ring and surrounds both the blades and inner ring, and a bell-mouthed airflow guide portion which structurally connects the inner ring and outer ring on the air exhaust side and has a diameter which is gradually enlarged in an air exhaust direction, a section of the airflow guide portion having the shape of part of a circle or ellipse, which starts from a point on an air-exhaust-side extension line of the inner ring and is connected to the outer ring, with the center and the point of tangency thereof both lying along an extension line of the outer ring.
