HEAT-TO-ELECTRIC-ENERGY CONVERTER Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: converter has permanent magnets, coils, and heat sources in the form of parallel heat pipes. Spherical flapping membrane is introduced in converter and placed symmetrically between heat pipes; its rigid center mounts cylindrical permanent magnets secured with their end surfaces on both sides of membrane; fixed coils are concentrically wound on magnets. Thermal bimetal flexible members are attached to free end surfaces of permanent magnets; one of them is brought in contact with nearest heat pipe and other one is spaced from other heat pipe through distance equal to membrane sag during its flapping. EFFECT: improved reliability of energy conversion. 1 dwg
