Flow-guiding apparatus and electronic device including the flow-guiding apparatus

An electronic device, comprising:

• a chassis being provided with an air vent, an axial fan being arranged at the air vent, and an air outlet of the axial fan being arranged with a flow-guiding apparatus,
• wherein the flow-guiding apparatus comprises a plurality of radial support and respective concentric surrounding flow-guiding members which are concentrically-mounted onto the plurality of radial support for guiding an air flow generated by the axial fan to a directed area towards only an axial center and away from the air outlet of the axial fan, a component requiring heat radiation is disposed downstream of the flow-guiding apparatus, the respective concentric surrounding flow-guiding members are connected to the support, at least two flow-guiding members comprises at least two surrounding inner flow-guiding members and at least two surrounding outer flow-guiding members which are respectively concentrically-mounted onto the plurality of radial support extending from a hub of the axial fan or around the hub of the axial fan in such a way that both the at least two surrounding inner flow-guiding members and the at least two surrounding outer flow-guiding members only open and tilt in a same direction to guide the generated airflow toward only the axial center of the axial fan along an air-blowing direction in response to the airflow generated by the axial fan;
• wherein an opening angle of the at least two surrounding outer flow guiding members ranges between 70° and 90°, and an opening angle of the at least two surrounding inner flow guiding members ranges between 30° and 65°.
