Document Type and Number:
Japanese Patent JP6586401
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic refrigeration device capable of increasing a maximum value in temporal change of strength of a magnetic field applied to a magnetism work substance, and capable of enhancing refrigeration capacity.SOLUTION: A magnetic refrigeration device includes a magnetic field generation part 9 provided rotatably, a heat generation part 11 provided on an outer peripheral side with respect to the magnetic filed generation part 9, and a yoke 12 provided on the outer peripheral side with respect to the heat generation part 11. The magnetic field generation part 9 has a plurality of permanent magnets PM aligned in a Halbach array along a rotational direction. The heat generation part 11 has a plurality of ducts DC arrayed along the rotational direction, and a plurality of magnetism work parts 13 stored in each of the plurality of ducts DC and each containing a magnetism work substance 14.SELECTED DRAWING: Figure 2
