Patent number: 11125477Abstract: A magnetic refrigeration apparatus includes one or more beds of magnetocaloric material arranged along a circumferential direction. The apparatus also includes a heat transfer fluid, one or more hot side heat exchangers (HHEX), one or more pumps or fluid displacement devices configured to move the heat transfer fluid, and a magnetic-field source. The magnetic-field source generates magnetic flux oriented substantially in a radial direction through the beds. The field source advantageously includes one or more pole pieces, one or more axial-end magnets, and one or more axial-end flux return pieces. Additionally, one or more circumferential flux returns, one or more gap flux return pieces, one or more side magnets, and one or more side flux return pieces can be added to increase system performance and reduce cost.Type: GrantFiled: August 25, 2017Date of Patent: September 21, 2021Assignee: Astronautics Corporation of AmericaInventors: Kyle Charles Rule, Jeremy Jonathan Chell, Andre Michael Boeder, Bryant Wayne Mueller, Steven Lee Russek, Carl Bruno Zimm, Markus Schwind
