ABSTRACT:
A heat-dissipating fan includes a casing having an air outlet, a base mounted in the air outlet, and a plurality of guiding plates in the air outlet. An impeller is mounted on the base that is supported in the air outlet by the guiding plates. The guiding plates are parallel to one another and extend in a direction having an inclining angle with respect to an axial direction of the air outlet. The guiding plates guide airflow and increase wind pressure when the impeller turns.
