A heat dissipation apparatus for effective dissipation of heat comprises an air flow module and a heat sink. The air flow module comprises a casing, a piston module slidably mounted in the casing, an airflow outlet module attached to a first side of the casing, and an electromagnet module attached to a second side of the casing that is opposite to the first side. The airflow outlet module comprises a plurality of airflow outlet grooves. The piston module comprises a magnet. The heat sink is aligned with the plurality of airflow outlet grooves. The electromagnet module is capable of moving the magnet and the piston module back and forth in the casing. The air flow module is capable of blowing air to the heat sink via the plurality of airflow outlet grooves.
