PROBLEM TO BE SOLVED: To provide a magnetic heat pump device capable of achieving capacity improvement while suppressing increase in size.SOLUTION: A magnetic heat pump device 10 includes: a motor 40 having a rotor 41; a hollow body 20 having a sealed space 201 in which a working fluid and an MCM 30 are accommodated, and capable of rotating together with the rotor 41; and a magnetic field application part 50 for applying a magnetic field to the MCM 30. The hollow body 20 includes: a first heat exchange part 21 for performing heat exchange with the outside air; a second heat exchange part 22 located on a relatively rotation outer peripheral side with respect to the first heat exchange part 21, and for performing heat exchange with the inside air; and a connection part 23 for connecting the first heat exchange part 21 and the second heat exchange part 22. The connection part 23 has thermal conductivity relatively lower than that of the first and second heat exchange parts 21, 22. The magnetic field application part 50 is arranged so as to oppose to a rotational orbit OP of the MCM 30.SELECTED DRAWING: Figure 2 |
