Abstract
An exemplary heat dissipation device includes a heat sink defining air passages therein, a fan holder fixedly mounted on the heat sink, a fan mounted on the fan holder, and an adjustable wind-guiding module located in and pivoted to the fan holder. The fan is positioned for generating an airflow flowing through the adjustable wind-guiding module generally toward the air passages of the heat sink. The adjustable wind-guiding module is selectably pivotable with respect to the fan holder such that a direction of the airflow generally toward the air passages of the heat sink is changed accordingly.
