Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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. 2. The regenerative refrigerator according to claim 1 , wherein an insertion member different from the magnetic regenerator material is accommodated in the first region of the container. 3. The regenerative refrigerator according to claim 1 , wherein the magnetic regenerator material includes HoCu 2 , and the first region is in a temperature range of 5 K-10 K during an operation of the regenerative refrigerator. 4. The regenerative refrigerator according to claim 1 , wherein the magnetic regenerator material includes Gd 2 O 2 S, and the first region is in a temperature range of 4.5 K-5.5 K during an operation of the regenerative refrigerator. 5. The regenerative refrigerator according to claim 1 , wherein the magnetic regenerator material includes HoCu 2 and Gd 2 O 2 S, and the first region is in a temperature range of 4.5 K-10 K during an operation of the regenerative refrigerator.
