摘要:
A thermomagnetic generator is provided, including a switch valve, a plurality of magnetic circuit units, a coil, and a plurality of inlet pipes connecting the magnetic circuit units to the switch valve. Each of the magnetic circuit units includes a magneto-caloric member. The switch valve repeatedly and alternatively switches at a predetermined frequency to guide hot and cold fluids to the magnetic circuit units, such that the magneto-caloric members are magnetized and demagnetized, respectively, by the cold and hot fluids. The coil is coupled to at least one of the magnetic circuit units for obtaining an induced voltage.

摘要:
A magnetocaloric module for a magnetic refrigeration apparatus includes: a bed having an inner surface; a magnetocaloric material filled in the bed; and an insulating layer formed over the inner surface, isolating the magnetocaloric material from the bed. With the use of the insulating layer, thermal conduction between the magnetocaloric material and the bed can be reduced and Galvanic corrosion which may occur to the bed can be prevented. Also, a temperature gradient of the magnetocaloric module may be further extended.
