Title:
MAGNETIC HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/150817
Kind Code:
A1
Abstract:
[Problem] To provide a magnetic heat pump device that makes it possible to improve the magnetic flux density obtained per permanent-magnet mass. [Solution] A magnetic heat pump device provided with: a permanent magnet 20 that can be rotated about a central axis CS of a rotating shaft 32, and the magnetization direction of an N-pole and an S-pole of which is parallel to a direction orthogonal to an axial direction of the central axis CS; a material container 22 that is arranged so as to surround the outer periphery of the permanent magnet 20 and that has a magnetic material 34 accommodated in the interior; and at least a pair of built-in yokes 26 that are respectively in contact with surfaces of different polarities of the permanent magnet 20 and that are separated from one another. The material container 22 is made of resin, and the built-in yokes 26 are ferromagnets and each have a portion that is closer to the material container 22 than the permanent magnet 20.
