Abstract: A magnetic cooling apparatus including a plurality of magnetic regenerators including a plurality of magnetocaloric materials to emit heat when magnetized and to absorb heat when demagnetized. The magnetic regenerators are rotatably disposed on a circumference having a predetermined radius, at least one coil is disposed on the circumference and coupled to the magnetic regenerators, and a plurality of permanent magnets is provided inside and outside the circumference to generate a magnetic field to magnetize or demagnetize the magnetic regenerators. The at least one coil interacts with the magnetic field generated by the permanent magnets to rotate the magnetic regenerators. The coil interacting with the magnetic field to magnetize or demagnetize the magnetic regenerators is coupled to the magnetic regenerators such that the magnetic regenerators reciprocate or rotate, thereby minimizing a size of the magnetic cooling apparatus, relative to the use of a motor. In addition, a member to switch a channel of a heat transfer fluid directly performs heat transfer between the heat transfer fluid and an external fluid, thereby minimizing heat loss.

Abstract: Cryogenic cooling apparatus is disclosed for cooling a target region using the demagnetization cooling effect. The apparatus has a primary magnet for providing a magnetic field within the target region and a demagnetization magnet arranged to selectively provide conductive cooling to the target region. A primary shielding magnet substantially cancels the magnetic field from the primary magnet at least at a first position between the primary and demagnetization magnets. A demagnetization shielding magnet substantially cancels the magnetic field from the demagnetization magnet at least at the first position between the primary and demagnetization magnets. Each of the primary shielding magnet and demagnetization shielding magnet comprises a cylindrical superconducting coil having a geometric envelope which encloses the primary magnet and demagnetization magnet respectively. A conductive cooling assembly provides conductive cooling to each of the magnets. A cryogenic system including a cryostat, the apparatus and a refrigeration system is also provided.

Abstract: A heat pump system is provided that uses MCM to provide for heating or cooling. The heat pump is constructed from a continuously rotating regenerator where MCM is cycled in and out of a magnetic field in a continuous manner. A heat transfer fluid is circulated therethrough to provide for heat transfer in a cyclic manner. The MCM may include stages having different Curie temperature ranges. A field of varying magnetic flux may be used. The rotating regenerator can be equipped with one or more gaskets to improve fluid seals between the rotating regenerator and stationary parts. An appliance using such a heat pump system is also provided. The heat pump may also be used in other applications for heating, cooling, or both.

Abstract: A parallel magnetic refrigerator assembly, includes at least two magnetocaloric stages arranged in parallel connection, each having in use a cold side and a hot side; each magnetocaloric stage including hot and cold side heat exchange circuit for carrying a heat exchange fluid to respectively receive and transfer heat from the magnetocaloric stages; wherein the hot and cold side heat exchange circuit are configured such that in use a heat exchange fluid passes in thermal contact with the respective hot and cold sides of both magnetocaloric stages. The magnetocaloric stages have substantially the same temperature spans but different cold end and hot end temperatures. In this way the device temperature span may be substantially larger than the individual temperature span of each magnetocaloric stage.
