摘要
为了提高热声效率转换,在黄铜和不锈钢这类传统热声堆材料的基础上,创造性地引入了毛细玻璃管和PVC塑料材质的热声堆。基于搭建以氩气为工质的扬声器驱动型热声制冷机,进行热声堆两端温差对制冷效果影响的实验研究。研究表明:当激励电流不变时,随着声场频率的升高,热声堆两端温差升高,制冷效果得到改善;当声场频率与激励电流相同时,毛细玻璃管材质输出的温差最大,制冷效果最佳。
On the basis of traditional thermal acoustic materials such as brass and stainless steel,the hot sound heap of capillary glass tubes and PVC plastic materials is put forward the first time.This article is based on the construction of a speaker-driven thermoacoustic refrigerator using argon as its working medium.An experimental study on the effect of temperature difference at the two ends of a thermoacoustic reactor on refrigeration performance is conducted.Study indicates that when the excitation current is constant,as the frequency of the sound field increases,the temperature difference between the two ends of the thermoacoustic reactor increases,and the cooling effect is improved.When the frequency of the sound field is the same as the excitation current,the temperature difference between the outputs of the capillary glass tube reaches the maximum,resulting in optimal cooling effect.
