摘要:

热声制冷技术可以高效地实现从普冷到低温的广泛温区,是目前低温与制冷领域的研究热点之一。它和相关的热声发动机技术都是利用精心布置的声学管道及换热器来实现能量转换和输运,可以无任何运动部件,结构简单,可靠性高。本文介绍了中国科学院理化技术研究所制冷与低温工程中心近年来围绕该项技术进行的研究,主要包括在基础热力学理论、热声低温和普冷制冷机以及热声系统CFD模拟方面取得的一些代表性进展。

Abstract:

Thermoacoustic refrigeration is one of most attractive research area in the field of cryogenics and refrigeration.Inside the thermoacoustic refrigerators and engines, energy conversion and transportation are realized through elaborately-arranged acoustic pipes and heat exchangers.This article introduces our recent research results, which cover the oscillating flow thermodynamics, thermoacoustic refrigerators for both cryogenic and domestic refrigeration and simulation with computational fluid dynamics.
