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.
