Electrical energy generating device, has element in contact with cold and hot fluids, where variation of temperature around element's Curie temperature induces variation of magnetic conductivity of element and variation of magnetic field

摘要

The device (1) has a valve (11) circulating cold and hot fluids e.g. water, and heat insulating fluid e.g. air, between inlet and outlet ends (7', 8', 7'', 8'') of pipes (7, 8) such that an element (2) with magneto-caloric property is in thermal contact with the cold and hot fluids in alternative manner. The variation of temperature around element's Curie temperature induces variation of magnetic conductivity of the element and variation of magnetic field in a magnetic flow conducting circuit (3). The circuit generates electric current using a magnetic field transformation unit (13). The temperature is varied due to thermal conduction between the element and cold and hot fluids.
