Abstract
A heat pump includes a magnet assembly which creates a magnetic field, and a regenerator housing which includes a body defining a plurality of chambers, each of the plurality of chambers extending along a transverse direction orthogonal to the vertical direction. The heat pump further includes a plurality of stages, each of the plurality of stages including a magnetocaloric material disposed within one of the plurality of chambers and extending along the transverse direction between a first end and a second end.
Claims20
A heat pump, comprising:
- a magnet assembly, the magnet assembly creating a magnetic field;
- a regenerator housing, the regenerator housing comprising a body defining a plurality of chambers, each of the plurality of chambers extending along a transverse direction orthogonal to the vertical direction;
- a plurality of stages, each of the plurality of stages comprising a magnetocaloric material disposed within one of the plurality of chambers and extending along the transverse direction between a first end and a second end;
- and
- a cam connected to one of the regenerator housing or the magnet assembly,
- wherein the one of the regenerator housing or the magnet assembly is movable relative to the other of the regenerator housing or the magnet assembly along a longitudinal direction orthogonal to the vertical direction and the transverse direction due to rotation of the cam.
