Abstract
A magneto-caloric thermal diode assembly includes a first magneto-caloric cylinder and a second magneto-caloric cylinder. First and second pluralities of thermal stages are stacked along an axial direction between a cold side and a hot side. The second magneto-caloric cylinder and the second plurality of thermal stages are nested concentrically within the first magneto-caloric cylinder and the first plurality of thermal stages. Each thermal stage of the first and second pluralities of thermal stages includes a plurality of magnets and a non-magnetic ring. The plurality of magnets is distributed along a circumferential direction within the non-magnetic ring in each thermal stage of the first and second pluralities of thermal stages.
