中文摘要:
      利用热声效应可以制造经济的热力发动机,包括热力泵和致冷机。文章介绍一种基于热声效应原理设计而成的台式热声致冷实验系统,该系统非常简单,由一些常见的装置构成。实验结果表明,在启动声致冷系统的几分钟内,温差即可达到10℃以上,实现了声致冷,从而有效地说明了热声致冷机的功效。
英文摘要:
      The thermoacoustic effect can be applied to produce powerful and reasonably efficient heat engines including heat pumps and refrigerator. This paper focuses on the design of an inexpensive tabletop thermoacoustic refrigerator for demonstration of the thermoacoustic effect. This thermoacoustic system has been built and tested. Experiental results show that temperature difference of more than 10℃ can be achieved after running for several minutes. It is clearly shown that the thermoacoustic refrigeration is very effective.
