  • Publication number: 20110274513
    Abstract: An exemplary securing structure includes a base, a fastener, and a spring mounted around the fastener. The base defines a through hole, and two slots located adjacent to and communicating with the securing hole. Two barriers are formed at a bottom of the base corresponding to the slots. A gap is defined between the bottom surface and each of the barriers. The fastener includes a head, a bolt, and two blocks extending outwardly from a periphery of the bolt corresponding to the slots, respectively. When the bolt is extended through the securing hole with the blocks extending through the slots until the blocks are received in the gaps, the fastener is then rotatable to cause the block to escape from the gap and abut on the bottom surface of the base, with the spring resiliently compressed between the head of the fastener and a top side of the base.

  • Publication number: 20110259557
    Abstract: A heat dissipation apparatus includes a heat sink defining a plurality of air passages therein, and an airflow generator arranged on the heat sink and including a plurality of airflow-generating units. Each airflow-generating unit includes a casing, and a vibration diaphragm and a driving member arranged in the casing. The vibration diaphragm divides an inner space of the casing into first and second chamber isolated from each other. The second chamber communicates with the exterior via an orifice defined in a bottom wall of the casing. The driving member is capable of vibrating the vibration diaphragm when alternating voltage is applied thereto. When the driving member vibrates the vibration diaphragm towards the bottom wall of the casing, the vibration diaphragm compresses the air inside the second chamber of the casing towards the orifice, generating airflow from the orifice to the air passages of the heat sink.

  • Publication number: 20110168361
    Abstract: An exemplary heat dissipation device includes a heat sink defining a plurality of air passages therein, and an airflow generator disposed at a side of the heat sink. The airflow generator includes airflow-generating units stacked together. Each airflow-generating unit includes a casing in which two spaced vibration diaphragms are received, and a nozzle connected to the casing. A chamber is defined between the two vibration diaphragms within the casing. The nozzle defines an air channel therein for communicating the chamber with an exterior of the casing. Two piezoelectric elements are respectively attached to the two vibration diaphragms. When the two piezoelectric elements drive the two vibration diaphragms towards each other, the two vibration diaphragms compress the air in the chamber and drive the air towards the air channel of the nozzle, thereby generating an airflow from the nozzle towards the air passages of the heat sink.
