    • A thermoacoustic cooling system for cooling an object such as a microelectronic chip. Heat produced by the object is transferred to a thermoacoustic engine. The thermoacoustic engine may include a resonator defining a chamber. A stack may be positioned in the chamber with one side of the stack adjacent to the heat source, and the opposite side of the stack adjacent to air in the chamber having a relatively cooler temperature. One or more orifices may be formed in the resonator such that the acoustic power generated by the thermoacoustic engine creates a synthetic jet to circulate air and move the air away from the object being cooled. Thus, the heat produced by the object is used to power the thermoacoustic engine to thereby remove heat from the object. The thermoacoustic engine may use no moving parts and may require no external power source other than the object being cooled.
    • 用于冷却诸如微电子芯片的物体的热声冷却系统。 由物体产生的热量传递到热声发动机。 热声发动机可以包括限定腔室的谐振器。 堆叠可以位于腔室中,堆叠的一侧与热源相邻,并且与腔室中的空气相邻的堆叠的相对侧具有相对较冷的温度。 可以在谐振器中形成一个或多个孔,使得由热声引擎产生的声功率产生合成射流以循环空气并将空气从被冷却的物体移开。 因此,由该物体产生的热量用于为热声发动机提供动力,从而从物体中除去热量。 热声发动机可以不使用移动部件,并且可能不需要除被冷却物体之外的外部电源。
