Abstract:
1. A thermo-magnetic engine apparatus comprising: a magnetic element having a high temperature end to which hot energy is supplied and a low temperature end to which cold energy is supplied, the magnetic element having a Curie temperature set between a temperature of the high temperature end and a temperature of the low temperature end, a magnetism of the magnetic element decreasing when a temperature of the magnetic element is equal to or higher than the Curie temperature and increasing when the temperature of the magnetic element is lower than the Curie temperature; a pump pumping heat transport medium toward the low temperature end from the high temperature end when the magnetic element is heated and pumping the heat transport medium toward the high temperature end from the low temperature end when the magnetic element is cooled; a magnetic-field applier that applies and removes an external magnetic field to the magnetic element; and a power source that gains magnetic power generated between the magnetic element and the magnetic-field applier as kinetic energy; wherein the magnetic element generates heat when an external magnetic field is applied to the magnetic element and absorbing heat when the external magnetic field is removed from the magnetic element to form a magneto-caloric element; the power source switches the external magnetic field between the applying of the external magnetic field and the removal of the external magnetic field by causing the magneto-caloric element and the magnetic-field applier to have a relative movement to form a magnetic field switcher; and the pump pumping the heat transport medium from the low temperature end toward the high temperature end when the external magnetic field is applied to the magneto-caloric element and pumping the heat transport medium from the high temperature end toward the low temperature end when the external magnetic field is removed from the magneto-caloric element.
