20110308258PARALLEL MAGNETIC REFRIGERATOR ASSEMBLY AND A METHOD OF REFRIGERATING - A parallel magnetic refrigerator assembly, includes at least: a first magnetocaloric stage having in use a cold side and a hot side; a second magnetocaloric stage having in use a cold side and a hot side, arranged in parallel connection with the first magnetocaloric stage; the first and second magnetocaloric stages each including a hot side heat exchange circuit for carrying a heat exchange fluid to receive heat from the magnetocaloric stages and a cold side heat exchange circuit for carrying a heat exchange fluid to transfer heat to the magnetocaloric stages; wherein the hot side heat exchange circuit is configured such that in use a heat exchange fluid passes in thermal contact with the hot side of both the first and second magnetocaloric stages and the cold side heat exchange circuit is configured such that in use a heat exchange fluid passes in thermal contact with the cold side of both the first and second magnetocaloric stages. The first and second AMR stages have substantially the same temperature span 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 AMR stage.12-22-2011

20120060513Magnetocaloric refrigerator - The invention is for an apparatus and method for a refrigerator and a heat pump based on the magnetocaloric effect (MCE) offering a simpler, lighter, robust, more compact, environmentally compatible, and energy efficient alternative to traditional vapor-compression devices. The subject magnetocaloric apparatus alternately exposes a suitable magnetocaloric material to strong and weak magnetic field while switching heat to and from the material by a mechanical commutator using a thin layer of suitable thermal interface fluid to enhance heat transfer. The invention may be practiced with multiple magnetocaloric stages to attain large differences in temperature. Key applications include thermal management of electronics, as well as industrial and home refrigeration, heating, and air conditioning. The invention offers a simpler, lighter, compact, and robust apparatus compared to magnetocaloric devices of prior art. Furthermore, the invention may be run in reverse as a thermodynamic engine, receiving low-level heat and producing mechanical energy.03-15-2012
