Abstract
A magnetic heat pump includes magnetocaloric members, an impeller, deformable members, a casing, an electric motor, and a magnetic field generator. The impeller has accommodation chambers. The deformable members face the accommodation chambers. The casing has an interior space accommodating the magnetocaloric members, the impeller, and the deformable members and allowing a heat transport medium to circulate, a first inlet, and a first outlet spaced apart from the first inlet in the circumferential direction. The magnetic field generator produces a magnetic field becoming stronger along the first direction, in a first region extending from the first inlet to the first outlet in the first direction in the interior space. The shapes of the deformable members individually change with the rotation. The volumes of the accommodation chambers individually increase and decrease with change in shape of the deformable members.
