Patent ID: RE40512

Claim:
An apparatus for promoting the cooling of an electronic device enclosing at least one heat-generating component, comprising: a signal detector for receiving a flow signal of a cooling medium inside the electronic device; a driver, in response to the flow signal from the signal detector, for providing a driving signal whose frequency is synchronized with a characteristic frequency of the flow of the cooling medium, wherein said characteristic frequency is a dominant frequency among analyzed frequency components of a flow signal of the heat-absorbing medium; and a vibrator, in response to the driving signal, for generating an acoustic wave to an interior of the electronic device, wherein the driver includes: a frequency analyzer for detecting the characteristic frequency of the flow of the cooling medium based on the flow signal; a frequency synchronizer for providing a frequency signal which represents the detected characteristic frequency; a signal generator, in response to the frequency signal from the frequency synchronizer, for providing the driving signal; and an amplifier for amplifying the driving signal to a predefined level.
