Patent ID: 7603865

Claim:
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.
