Title:
AIRFLOW CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/032458
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide an airflow control system that can control the diffusion of airflow. This airflow control system (1a, 1b, 1c, 1d) comprises a tubular body (2), a fan (3), a first rectifying mechanism (4a, 4b), a second rectifying mechanism (5a, 5b), and an airflow control unit (6a, 6b, 6c, 6d). The tubular body (2) has a gas inflow port (23) on a first end (21), a gas outflow port (24) on a second end (22), and a flow path (25) connecting the inflow port (23) and the outflow port (24), the flow path (25) having a circular cross-section. The fan (3) is disposed inside the tubular body (2) and generates airflow, which is a flow of air. The first rectifying mechanism (4a, 4b) is positioned between the fan (3) and the outflow port (24) in an axial direction (D1) of the tubular body (2) and diverts the airflow. The second rectifying mechanism (5a, 5b) is positioned between the first rectifying mechanism (4a, 4b) and the outflow port (24) in the axial direction (D) and aligns the orientation of the airflow with an orientation along the axial direction (D1). The airflow control unit (6a, 6b, 6c, 6d) changes the rectifying state of the airflow.
