STIRLING TYPE REFRIGERATOR

PROBLEM TO BE SOLVED: To realize both of high reliability and low costs without a complicated structure such as a leaf spring structure.SOLUTION: The Stirling type refrigerator comprises: a compression section 7a filled with refrigerant gas; a high-temperature heat exchanger 9 communicated with the compression section 7a; a cold storage device 11 communicated with the high-temperature heat exchanger 9; a low-temperature heat exchanger 13 communicated with the cold storage device 11; and an expansion section 14 adjacent to the low-temperature heat exchanger 13. A predetermined phase difference is provided between pressure variation on the compression section 7a side and pressure variation on the expansion section 14 side, so as to cool the expansion section 14. The compression section 7a is formed by air-tightly mounting an opening edge 201 of bellows 20 formed into an almost cup-shape to the high-temperature heat exchanger 9, and a first external drive source 1 is mounted to a blocking plate section 202 of the bellows 20, so as to periodically vary a capacity of the compression section 7a.
