REGENERATOR, MANUFACTURING METHOD THEREFOR, STERLING ENGINE, AND STERLING REFRIGERATOR/FREEZER

摘要

PROBLEM TO BE SOLVED: To provide a regenerator of high efficiency, a manufacturing method therefor, a sterling engine and a sterling refrigerator/freezer.;SOLUTION: This regenerator provided in this sterling engine includes a regenerator film 31 wound with a clearance. The regenerator film 31 has multilayered structure layered with the first film 31A and the second film 31B. A protruded part is formed in the regenerator film 31, by pressing a surface thereof along a DR3 direction or DR4 direction to be deformed plastically. The first film 31A has regenerativeness higher than that of the second film 31B, and the second film 31B has a Young's modulus higher than that of the first film 31A.;COPYRIGHT: (C)2007,JPO&INPIT
