PROBLEM TO BE SOLVED: To improve a device for transporting heat from a cold reservoir to a warm reservoir so as to transport heat in such a manner that the expense of the device is considerably reduced and the efficiency and power density of the device are increased. SOLUTION: The device for transporting heat from a cold reservoir to a warm reservoir employs at least two cyclic processes for transporting heat, thereby absorbing work, of which at least one is a regenerative cyclic process and at least one is a magnetocaloric cyclic process, wherein the regenerative cyclic process has a working fluid and a heat storage medium. The heat storage medium of the regenerative cyclic process comprises a magnetocaloric material for the magnetocaloric cyclic process, wherein the magnetocaloric material is in a regenerator area 1, 1', 1" with a cold end 2' and a warm end 2, and the working fluid of the regenerative cyclic process additionally serves as a heat transfer fluid for the magnetocaloric cyclic process. This produces a compact device with low device expense, wherein the power density and also the efficiency of the device are increased. The device may advantageously be used for a superconducting magnet configuration. COPYRIGHT: (C)2007,JPO&INPIT |
