A cantilevered beam structure with acoustic black hole characteristics is used as an oscillating heat dissipation fin to efficiently dissipate heat in the structure to an external fluid. By amplifying the amplitude of vibration of a beam through the acoustic black hole characteristics, the heat transfer coefficient from a beam structure to external fluid is expected to increase. In this study, we investigate the effectiveness of the large amplitude of vibration of the tip of the beam, which is generated by the acoustic black hole characteristics, and the accompanying oscillation of external fluid on the heat transfer.
