THERMOMAGNETIC POWER GENERATION APPARATUS USING THERMOSENSITIVE MAGNETIC SUBSTANCE

摘要

PURPOSE: To change low-temperature thermal energy into electric energy with high conversion efficiency by a method wherein thermosensitive magnetic substances are built into magnetic circuits, thermal energy is applied alternately to the thermosensitive magnetic substances, a change in a magnetic-flux is formed and the change is taken out as AC electric energy by an output coil. ;CONSTITUTION: Warm water 9 and cold water 10 are changed over by a changeover valve 5, and they are sent into containers 1A, 1B which contain particles of a thermosensitive magnetic substance. When the warm water is sent, the temperature of the thermosensitive magnetic substance becomes the Curie point or higher, it looses a magnetic property, and a magnetic flux does not flow. When the cold water is sent, the permeability of the thermosensitive magnetic substance is increased, and a magnetic flux flow into magnetic circuits A, B as shown by arrows. Since an output coil 3 is wound in the magnetic circuits A, B, a change in the magnetic flux is output to output terminals 11 as AC electric energy. Thereby, low-temperature thermal energy can be changed into electric energy with high conversion efficiency.;COPYRIGHT: (C)1995,JPO
