Abstract

A passive thermoacoustic cooling apparatus that could be miniaturized for cooling of microelectronics components was proposed. The passive thermoacoustic cooling apparatus is composed of a resonant chamber, a temperature-difference element and a heat conduction element. The temperature-difference element is situated in the resonant chamber and could transfer heat into acoustic power. The heat conducting element connects heat load and the temperature-difference element. The heat conducting element transmits heat from heat load to one end of the temperature-difference component. By forming temperature gradient on the temperature-difference element, acoustic standing wave is formed in the resonant chamber. Therefore, forced air convection is generated to cool the heat load.
