1. A heat pump, comprising:
- a first frame body;
a second frame body spaced apart from the first frame body along a lateral direction;
a magnet disposed between the first and second frame bodies along the lateral direction, the magnet generating a magnetic field;
a regenerator housing comprising a body, a first stage and a second stage, the body defining a plurality of chambers that extends along the lateral direction, the first and second stages each comprising a magneto-caloric material disposed within a respective chamber of the plurality of chambers, the regenerator housing movable along the lateral direction between a first position and a second position relative to the magnet, the first stage positioned within the magnetic field of the magnet and the second stage positioned remote from the magnetic field of the magnet when the regenerator housing is in the first position, the second stage positioned within the magnetic field of the magnet and the first stage positioned remote from the magnetic field of the magnet when the regenerator housing is in the second position;
a first compliant seal extending between the first frame body and the regenerator housing along the lateral direction in both the first and second positions of the regenerator housing; and
a second compliant seal extending between the second frame body and the regenerator housing along the lateral direction in both the first and second positions of the regenerator housing.

Abstract
A heat pump includes a regenerator housing that is movable along a lateral direction between a first position and a second position. A first compliant seal extends between a first frame body and the regenerator housing along the lateral direction. A second compliant seal extends between a second frame body and the regenerator housing along the lateral direction.

11. A heat pump, comprising:
-
a first frame body; a second frame body spaced apart from the first frame body along a lateral direction; a field generator disposed between the first and second frame bodies along the lateral direction, the field generator having a field; a regenerator housing comprising a body, a first stage and a second stage, the body defining a plurality of chambers that extends along the lateral direction, the first and second stages each comprising a caloric material disposed within a respective chamber of the plurality of chambers, the regenerator housing movable along the lateral direction between a first position and a second position relative to the field generator, the first stage positioned within the field of the field generator and the second stage positioned remote from the field of the field generator when the regenerator housing is in the first position, the second stage positioned within the field of the field generator and the first stage positioned remote from the field of the field generator when the regenerator housing is in the second position; a cold side head exchanger in fluid communication with the plurality of chambers of the regenerator housing such that working fluid is flowable between the cold side head exchanger and the plurality of chambers of the regenerator housing; a hot side head exchanger in fluid communication with the plurality of chambers of the regenerator housing such that the working fluid is flowable between the hot side head exchanger and the plurality of chambers of the regenerator housing; a first compliant seal disposed between the cold side head exchanger and the hot side head exchanger along a transverse direction that is perpendicular to the lateral direction, the first compliant seal extending between the first frame body and the regenerator housing along the lateral direction; and a second compliant seal disposed between the cold side head exchanger and the hot side head exchanger along the transverse direction, the second compliant seal extending between the second frame body and the regenerator housing along the lateral direction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
