Author(s) : INOUE T.

Type of article: Article

Summary

The paper briefly reviews the developments of several types of pulse-tube refrigerators, and an explanation of the cooling mechanisms is presented. According to the thermo-acoustical consideration, tremendous differences in refrigeration power between the basic and orifice types can be understood as follows: flow impedance of an orifice enhances the progressive-wave part of the working gas oscillations which causes large increases in heat transfer through a regenerator.
