Abstract: An electronic device with a power generator has a rotational component, a power generator, a commutator, a battery charger, and a transmission component. The commutator is electrically coupled with the power generator. The battery charger is electrically coupled with the commutator for providing a charging power source. The transmission component is coupled between the rotational component and a shaft. When the rotational component rotates, the rotational component drives the transmission component so as to make the shaft rotate and make a coil generate an induced current. The induced current is transmitted into the commutator. An output of the commutator is used to charge the battery charger.

Abstract: A heat sink comprises a hollow body and a working fluid contained inside the hollow body. The hollow body is made of a heat-conductive material and further has a heat absorption end and a heat dissipation end. The heat absorption end has a bottom for contacting with a heat-generating element. The heat dissipation end has a plurality of protrusions for increasing surface exposed to surrounding air. The working fluid at the heat absorption end absorbs heat generated by the heat-generating element to be transformed from a liquid state to a gas state. Then, the working fluid in the gas state rises to the protrusions of the heat dissipation end for dissipating the heat to the surrounding air. The working fluid is transformed from the gas state to the liquid state to flow down back to the heat absorption end.
