| 1. A magnetic refrigerator, comprising:
a plurality of magnetic heat exchange units configured to exchange heat with a flow of a heat transfer fluid, each unit including
a case including an upper case and lower case and a magnetocaloric material sealed in the case to prevent direct contact between
the magnetocaloric material and the heat transfer fluid, a temperature of the magnetocaloric material changing when a magnetic
field is applied;
a rotating plate comprising a plurality of mounting holes disposed along a circumference of the rotating plate, the plurality
of magnetic heat exchange units being mounted in the mounting holes and having a predetermined distance therebetween;
a magnet disposed along portions of an upper surface and a bottom surface of the rotating plate, the magnet applying a magnetic
field to increase the temperature of the magnetic heat exchange units in the magnetic field;
a hot heat exchange member disposed at a hot side of the plurality of magnetic heat exchange units; and
a cold heat exchange member disposed at a cold side of the plurality of magnetic heat exchange units,
wherein the heat transfer fluid is divided into a first heat transfer fluid circulating in the hot heat exchange member and
a second heat transfer fluid circulating in the cold heat exchange member.
