Abstract
An airflow guiding structure for the heat dissipation fan includes a housing, a base and a plurality of guiding members. The housing is formed with an air outlet at which the base and the guiding members are provided. The base is used to support a fan wheel and supported by the guiding members. The guiding members are arranged in at least two guiding directions at the air outlet and at least one of the guiding members is inclined to an axis of the housing. When the fan wheel rotates, the guiding members guide airflow to the two guiding directions.

An airflow guiding structure for a heat dissipation fan, comprising:
- a housing provided with an air inlet and an air outlet, and an annular wall between the air inlet and the air outlet;
- a base mounted in the air outlet for supporting a fan wheel which formed with a plurality of blades;
- at least one auxiliary air outlet formed in the annular wall of the housing proximate the air outlet;
- and
- a plurality of guiding members arranged in the air outlet and inclined with respect to an axis of the housing, the auxiliary air outlet being adjacent to at least one of the guiding members, said at least one of said guiding members guiding air to said auxiliary air outlet;
- wherein when the fan wheel rotates, the guiding members deflect airflow in at least two airflow directions, including at least a first airflow direction at the air outlet and at least a second airflow direction at the auxiliary air outlet.
