Résumé

Regenerators in standard pulse-tube refrigerators are expensive, complicated, heavy, and they contribute significantly to the losses in the cooler. In the research, the regenerators are avoided by using two identical GM-type pulse-tube refrigerators operating in opposite phase. The two regenerators are replaced by one counterflow heat exchanger. This system is called the counterflow pulse-tube refrigerator. A special feature of the system is that the pressure wave is generated by a rotating valve at low temperature. The basic principle of the processes in the counterflow pulse-tube refrigerator are discussed and some preliminary experimental results are given.
