美国洛斯阿拉莫斯国家实验室,制出一种液体金属声热发电机。样机由一支长金属管组成,管两头密封并充以液态钠。用钼制成的几层薄平行板放在缸体里。传导液体的两套小管使板的一端保持在125℃,另一端在700℃。由于温差液态钠开始振荡发出声音。在管子中有磁场时,这些振荡便产生电流。该发电机优点是不需传动机械,可靠性高。它主要用于为卫星提供电能和一些可靠性要求严 Los Alamos National Laboratory, the United States, made a liquid metal sound heat generator. The prototype consists of a long metal tube sealed and filled with liquid sodium. Several layers made of molybdenum thin parallel plate placed in the cylinder. The two sets of conduits that conduct the liquid keep one end of the plate at 125 ° C and the other end at 700 ° C. As the temperature difference began to oscillate liquid sodium sound. When there is a magnetic field in the tube, these oscillations generate current. The advantage of this generator is that it does not need to drive the machine and has high reliability. It is mainly used to provide power to satellites and some reliability requirements
