Magnetic refrigeration device and magnetic refrigeration system

摘要

In a magnetic refrigeration device, magnetic bodies having a magnetocaloric effect and solid heat accumulation members (3, 3A, 3B) having heat accumulation effect are arranged alternately with gaps (4) therebetween. Magnetic field apply units (6A, 6B) start and stop application of magnetic fields to the magnetic bodies. A contact mechanism brings each of the magnetic bodies into contact with one of the solid heat accumulation members (3, 3A, 3B) adjacent to the each magnetic body (2). Alternatively, the contact mechanism brings each of the solid heat accumulation members (3, 3A, 3B) into contact with one of the magnetic bodies adjacent to the each solid heat accumulation members (3, 3A, 3B).
