<p><P>PROBLEM TO BE SOLVED: To provide a magnetic refrigerating device capable of reducing magnet running torque, improving operating efficiency, and performing stable operation by making magnet rotation smooth. <P>SOLUTION: A stator 11 that composes a magnetic refrigerating device 10 is formed in a cylindrical fashion, and a permanent magnet 17 is supported at the axis position in the stator 11 in a rotatable condition. A gap between the stator 11 and the permanent magnet 17 is filled with a magnetic material 21 and also keeps a plurality of ducts for heat exchange 22 arranged to circulate coolant water. A dummy duct plate 24 made of nonmagnetic material is formed at the center position in a circumferential direction in the duct for heat exchange 22 and extends in the radial direction of the stator 11, and is disposed in a way to be able to divide the inside of the duct for heat exchange 22. In the dummy duct plate 24, a plurality of communication holes for circulating coolant water are opened. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
