Abstract
A regenerator of a regenerative refrigerator includes: a magnetic regenerator material used for cold storage; and a container that accommodates the magnetic regenerator material. A part of the container that accommodates the magnetic regenerator material includes: a first region that includes a temperature range in which a specific heat of the magnetic regenerator material reaches maximum during an operation of the regenerative refrigerator, and a second region that is in a temperature range different from that of the first region. A cross sectional area of a part of the first region that accommodates the magnetic regenerator material is smaller than a cross sectional area of a part of the second region that accommodates the magnetic regenerator material.
Claims5
A regenerative refrigerator comprising:
- a regenerator that includes:
- a magnetic regenerator material used for cold storage;
- and
- a container that accommodates the magnetic regenerator material,
- wherein a part of the container that accommodates the magnetic regenerator material includes:
- a first region that includes a temperature range in which a specific heat of the magnetic regenerator material reaches maximum during an operation of the regenerative refrigerator, and a second region that is in a temperature range different from that of the first region, the first region divided from the second region in an axial direction of the regenerator, and
- a first cross sectional area of a part of the first region that accommodates the magnetic regenerator material is smaller than a second cross sectional area of a part of the second region that accommodates the magnetic regenerator material, the first cross sectional area and the second cross sectional area being perpendicular to the axial direction of the regenerator.
