Abstract:
1. A heat-dissipating fan housing comprising: a casing including a compartment having two ends respectively defining an air inlet and an air outlet spaced in an axial direction, with the compartment including an impeller section, a stationary blade section, and an airflow concentration section arranged from the air inlet toward the air outlet, with the stationary blade section being between the impeller section and the airflow concentration section in the axial direction, with the impeller section adapted for rotatably receiving an impeller; a mounting portion received in the compartment, with the impeller adapted to be rotatably coupled to the mounting portion for driving airflows to enter the casing via the air inlet and to exit the casing via the air outlet; and a plurality of stationary blades interconnected between the casing and the mounting portion, with the plurality of stationary blades received in the stationary blade section, with each of the plurality of stationary blades including a first edge facing the air inlet and a second edge facing the air outlet, with the airflow concentration section being between the second edge of each of the plurality of stationary blades and the air outlet in the axial direction, and with the airflow concentration section concentrating the airflows after passing through the plurality of stationary blades.
