US Patent 10989449 Magneto-caloric thermal diode assembly with radial supports

A magneto-caloric thermal diode assembly includes a magneto-caloric cylinder. A plurality of thermal stages is stacked along an axial direction between a cold side and a hot side. A plurality of supports is positioned within the plurality of thermal stages. The plurality of supports is distributed along the axial direction. The plurality of supports contacts the magneto-caloric cylinder such that the plurality of supports limits deflection of the magneto-caloric cylinder along a radial direction. 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.
