C02 Study on Single Piston Stirling Refrigerator Using a Double Tube for the Flow Area

A refrigerator using a double tube was proposed to miniaturize the pulse tube refrigerator. To design a double tube refrigerator, experiments changing parameters such as pulse tube volume, tube length, tank volume were carried out by a pulse tube refrigerator. On the basis of experimental results refrigerator using a double tube for the flow area composed of regenerator and tank was constructed. Experiment by double tube type refrigerator was carried out. However, cooling performance was not obtained. Then structure of double tube type refrigerator was reconsidered and its improvement was proposed.
