热声技术是基于热致声效应的一种技术,它可以将热能转化为声能,进而用于发电或制冷等。特别是热声发电技术是一种全新的热发电技术,可将热能转化为声能并直接由直线发电机等换能设备产生电能。由于热声发动机无机械运动部件,可实现高效率的声学斯特林循环,且采用外燃式工作,因 Thermoacoustic technology is a technology based on the thermo-acoustic effect, which converts heat energy into sound energy, which can then be used for power generation or refrigeration. In particular, thermoacoustic power generation technology is a new type of thermal power generation technology that converts heat energy into acoustic energy and directly generates energy from transducing devices such as linear generators. Due to the thermoacoustic engine without mechanical moving parts, high-efficiency acoustic Stirling cycles can be achieved and the use of external combustion
