CURIE POINT OSCILLATION GENERATION METHOD AND DEVICE THEREOF

摘要

A Curie point oscillation generation method includes a soft magnet (1) is continuously heated and cooled in a magnetic path composed of a permanent magnet (9) or an electromagnet, the soft magnet (1) and a coil (8) with an iron core (7) to make the temperature of the soft magnet (1 ) oscillate periodically up and down at the Curie point so that the soft magnet (1 ) is continuously magnetized or demagnetized and magnetic flux in the coil (8) is periodically increased or reduced to induce continuous alternating current power. A Curie point oscillation generation device includes the soft magnet (1 ) formed by laminating a plurality of soft magnetic sheets (2) insulated from each other. One side surface of the soft magnet (1) is connected to a heating cylinder (4) and the other side surface of the soft magnet (1) is connected to a cooling cylinder (5) with a piston (6) disposed therein An air gap between every two adjacent soft magnetic sheets (2) communicates the heating cylinder (4) with the cooling cylinder (5). A closed space formed by the heating cylinder (4), the air gap or air hole between the soft magnetic sheets (2) and the cooling cylinder (5) is filled with a working medium gas. The method and the device have an efficient and steady power generation process and a function of direct and efficient conversion from heat energy to electric energy.
