Patent ID: 8729718

Claim:
A thermomagnetic generator, comprising: a switch valve; a hot liquid source; a hot liquid pipe, connecting the hot liquid source to the switch valve, wherein a hot fluid is pumped through the hot liquid pipe to the switch valve; a cold liquid source; a cold liquid pipe, connecting the cold liquid source to the switch valve, wherein a cold fluid is pumped through the cold liquid pipe to the switch valve; a plurality of magnetic circuit units, wherein each of the magnetic circuit units comprises a magneto-caloric member; a plurality of inlet pipes, respectively, connecting the magnetic circuit units to the switch valve, wherein the switch valve repeatedly switches at a predetermined frequency to guide the hot and cold fluids through the inlet pipes to the magnetic circuit units, and wherein the magneto-caloric members are magnetized and demagnetized in turns by the cold and hot fluids; and a coil, coupled to at least one of the magnetic circuit units for obtaining an induced voltage.
