Magneto-caloric thermal diode assembly with an axially pinned magneto-caloric cylinder

A magneto-caloric thermal diode assembly, comprising:

• a magneto-caloric cylinder comprising a plurality of magneto-caloric stages and a plurality of insulation blocks, the plurality of magneto-caloric stages and the plurality of insulation blocks distributed sequentially along an axial direction in the order of magneto-caloric stage then insulation block within the magneto-caloric cylinder, each of the plurality of magneto-caloric stages having a respective Curie temperature, the magneto-caloric cylinder further comprising a plurality of pins, one or more of the plurality of pins extending along the axial direction between each of the plurality of magneto-caloric stages and a respective insulation block within the magneto-caloric cylinder;
• and
• a plurality of thermal stages stacked along the axial direction between a cold side and a hot side, each of the plurality of thermal stages comprises a plurality of magnets and a non-magnetic ring, the plurality of magnets distributed along a circumferential direction within the non-magnetic ring in each of the plurality of thermal stages;
• wherein the plurality of thermal stages and the magneto-caloric cylinder are configured for relative rotation between the plurality of thermal stages and the magneto-caloric cylinder.
