THERMO-ELECTRIC BATTERY Russian patent published in 2006 - IPC H01L35/28 

FIELD: engineering of thermo-electric batteries.

SUBSTANCE: thermo-electric battery consists of semiconductor thermo-elements, connected in electric circuit by means of commutation plates, each one of aforementioned thermo-elements is formed by two branches, made of semiconductor of resistor p- and n-type. Electric connection of branches is realized by contact: p-type branch - commutation plate - n-type branch, where p-type branch end surface is in contact with one of surfaces of commutation plate, and n-type branch - with another one. Each branch contacts two commutation plates by opposite end surfaces. Odd(even) commutation plates have area, which is somewhat greater, than area of transverse section of p- and n-type branches. Their ends project beyond surface of structure, formed by branches of thermo-electric battery. Free ends of odd(even) commutation plates are soldered to areas, electro-isolated from one another, made in form of films of metals or alloys, applied onto ceramic plate. Each even(odd) commutation plate in its central part has a through aperture. Apertures of all commutation plates by means of electro-isolation pipelines are joined in unified channel, along which during functioning of thermo-electric battery cooling liquid is pumped. Space, limited by ceramic plate and upper surface of structure, formed by branches of thermo-electric battery, is filled with electro-isolation. A layer of electro-isolation is also applied to remaining surface of thermo-electric battery.

EFFECT: increased temperature drops on thermo-battery and decreased metal consumption.
