Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0018] Before describing the regenerator according to the embodiment of the present invention, a regenerator-type refrigerator using the regenerator according to the embodiment will be described.

[0019] figure 1 It is a schematic diagram which shows an example of the regenerator type refrigerator 1 which concerns on embodiment. The regenerator refrigerator 1 according to the embodiment is, for example, a Gifford-McMahon (GM) cryogenic refrigerator using helium gas as a refrigerant gas. Such as figure 1 As shown, the regenerator refrigerator 1 includes a first displacer 2 and a second displacer 3 connected to the first displacer 2 in the longitudinal direction. The first displacer 2 and the second displacer 3 are connected via, for example, pins 4 , connectors 5 , and pins 6 .

[0020] The first cylinder 7 and the second cylinder 8 are integrally formed, and each h...

Abstract

The invention provides a regenerator and a regenerator type refrigerator. The present invention provides a technology for suppressing the amount of cold storage material used while maintaining the refrigeration performance of a cold storage refrigerator. The regenerator (34) of the present invention accumulates the cold generated by the expansion of refrigerant gas, and the regenerator (34) includes: a regenerator material made of a non-magnetic material, a regenerator material made of a magnetic material, and a container, and the container has The high-temperature end and the low-temperature end accommodate a regenerating material made of a non-magnetic material at the high-temperature end side, and accommodate a regenerating material made of a magnetic material at the low-temperature end side. The container also accommodates an insert member (35) that changes the flow path area of ​​refrigerant gas flowing through the region containing the cold storage material made of magnetic material so that the flow path area on the low-temperature end side is larger than that on the high-temperature end side. The flow path area is narrow.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2014-017385 filed on January 31, 2014. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The present invention relates to a regenerator that stores cold generated by Simon expansion of high-pressure refrigerant gas supplied from a compression device, and a regenerator-type refrigerator including the regenerator. Background technique [0003] As the regenerator type refrigerator, there is a refrigerator described in Patent Document 1, for example. In the displacer type regenerator type refrigerator, the displacer is reciprocated inside the cylinder and the refrigerant gas in the expansion space is expanded to generate cold. In addition, in the pulse tube type regenerator type refrigerator, the gas piston in the pulse tube is reciprocated and the refrigerant gas in the expansion space is expanded to generate cooling. The coldness of t...
