A magnetic refrigeration apparatus (10) is modular in design, so that housing modules (14) are alternately stacked with superconducting magnet pairs (24). Each module (14) has a wheel (16) that is rotated through the module (14), the wheel (16) having cutout regions (18) into which elements (20) of magnetic material are inserted. Each cutout region has two elements (20) separated by a wave spring, the wave spring biasing the elements (20) against the housing module (14) so that the elements (14) are in slidable contact with the module (14) upon rotation....
Magnetic refrigeration apparatus comprising: (a) magnetic material which exhibits the magnetocaloric effect mounted for movement; (b) means for producing a magnetic field at a position over a portion of the magnetic material such that each point of the magnetic material can be moved into and out of the magnetic field as the material is moved; (c) a high temperature heat exchanger located proximate the portion of the magnetic material in the magnetic field; (d) means for conducting liquid helium through the high temperature heat exchanger; (e) a low tempe...
