A heat dissipation apparatus (10) for dissipating heat from a heat-generating electronic component includes a fin assembly (12) and a centrifugal blower (14). The fin assembly includes a plurality of laminar fins (121) thermally connecting with the heat-generating electronic component to absorb heat therefrom. The centrifugal blower provides an airflow flowing through the fin assembly to take heat away therefrom. The centrifugal blower includes a housing (141), a cover (142) disposed on the housing, and a rotor (143) rotatably received in a space formed between the housing and the cover. The fins of the fin assembly are disposed in the housing of the centrifugal blower and stacked together along a direction substantially parallel to a rotation axis (A) of the rotor.
