Magneto-caloric thermal diode assembly with a rotating heat exchanger
First Claim
1. A magneto-caloric thermal diode assembly, comprising:
- a magneto-caloric cylinder;
a plurality of thermal stages stacked along an 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, the plurality of thermal stages and the magneto-caloric cylinder configured for relative rotation between the plurality of thermal stages and the magneto-caloric cylinder; and
a heat exchanger comprisinga cylindrical stator positioned at and in thermal communication with the cold side or the hot side of the plurality of thermal stages;
a cylindrical rotor spaced from the cylindrical stator by a cylindrical gap, the cylindrical rotor configured to rotate relative to the cylindrical stator about a rotation axis;
wherein a shearing liquid zone is defined between a surface of the cylindrical stator that faces the cylindrical gap and a surface of the cylindrical rotor that faces the cylindrical gap when the cylindrical gap is filled with a liquid.

Abstract
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 heat exchanger includes a cylindrical stator positioned at and in thermal communication with the cold side or the hot side of the plurality of thermal stages. A cylindrical rotor is spaced from the cylindrical stator by a cylindrical gap. The cylindrical rotor is configured to rotate relative to the cylindrical stator about a rotation axis. A shearing liquid zone is defined between a surface of the cylindrical stator that faces the cylindrical gap and a surface of the cylindrical rotor that faces the cylindrical gap when the cylindrical gap is filled with a liquid.
