CONVERTER OF TEMPERATURE DIFFERENCE ENERGY WITH LIQUID METAL ELECTRODE Russian patent published in 2014 - IPC H02M3/04 

FIELD: power engineering.

SUBSTANCE: invention relates to capacitance converters of energy and may be used to supply low-capacity energy loads under climatic conditions with sufficient periodical temperature difference. The device comprises two capacitance plates, one of which is fixed, and the second one, movable, is made of liquid metal, for instance, mercury. The device also comprises a bar from any dielectric heat-sensitive material, having high variation of its linear dimensions in case of change of external temperature. The second end of this bar is rigidly fixed on the fixed base. Between the fixed plate of the capacitor and the unfixed end of the bar from dielectric heat sensitive material there is a material placed, which has high relative dielectric permeability, for instance, segnetoelectric. At the same time one part of the dielectric is tightly fixed to the fixed capacitance plate, and the opposite part faces the unfixed end of the bar. Between this part of segnetoelectric and the end of the bar there is a small air gap arranged, in which a small amount of mercury is placed. Thus the device creates a reservoir, in which one of movable plates is liquid metal, for instance, mercury. The device also has a source of DC excitation and contacts required for capacitance charging.

EFFECT: increased produced voltage on a load.
