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 vibration of a beam structure with the acoustic black hole characteristics, the heat transfer from a beam structure to the external fluid is expected to increase. In this study, we investigate the effect of the flow of air and vibration of the tip of the beam structure on the heat transfer. As a result, it is confirmed that the heat transfer coefficient of a beam with an acoustic black hole is largely improved by the large amplitude of vibration at the tip of the beam and the flow of air.
