Thermoelectric generator and method of generating electricity |
摘要 |
A generator device for converting thermal energy to electric energy. A magnetic circuit includes at least a portion made of a magnetic material. A temperature-varying device varied the temperature in the portion made of the magnetic material alternately above and below a phase transition temperature of the magnetic material to thereby vary the reluctance of the magnetic circuit. A coil is arranged around the magnetic circuit, in which electric energy is induced in response to a varying magnetic flux in the magnetic circuit. A magnetic flux generator creates magnetic flux in the magnetic circuit. The temperature-varying device alternately passes hot and cold fluid by, or through holes in, the portion made of the magnetic material of the magnetic circuit in a single direction to thereby vary the temperature in the portion made of the magnetic material alternately above and below the phase transition temperature of the magnetic material. |
