Abstract:
An airflow is suppressed from diffusing. In an airflow control system (1), a tube body (2) includes an inflow port (23) for gas and an outflow port (24) for gas. A first rectifying device (4) is located between a fan (3) and the outflow port (24) in an axial direction (D3) of the fan (3) and is configured to redirect an airflow which is swirling. A second rectifying device (5) is located between the first rectifying device (4) and the outflow port (24) in the axial direction (D3) and is configured to align the direction of the airflow with a direction along the axial direction (D3). The first rectifying device (4) includes a tube part (41) which is cylindrical and a plurality of fins (42). Each of the plurality of fins (42) has an arc shape. The plurality of fins (42) protrude from an inner circumferential surface (413) of the tube part (41) toward a central axis (40) of the tube part (41) and are aligned in a direction along an inner circumference of the tube part (41). The second rectifying device (5) includes a plurality of flow paths (55) along the axial direction (D3).
