THERMOELECTRIC BATTERY Russian patent published in 2006 - IPC H01L35/28 

FIELD: thermoelectric battery mechanical design.

SUBSTANCE: proposed thermoelectric battery has semiconductor thermal cells connected in series to form electric circuit by means of switching wafers, each cell being formed by two p and n semiconductor legs, respectively. Legs are electrically interconnected through circuit set up of p switching wafer, n leg, where p leg comes in contact through butt-end surface with one of switching wafer surfaces and n leg, with other surface. Each leg contacts two opposing switching wafers through butt-end surfaces. Switching wafers have through holes. Holes made in even- and odd-numbered switching wafers are made in mutually perpendicular planes. Holes of all odd-numbered switching wafers are joined in tandem by means of insulating pipelines to form single channel that carries coolant when thermoelectric battery is operating. Holes of all even-numbered switching wafers are joined in tandem in the same manner to form second channel. Thermoelectric battery and pipelines are provided with heat insulation isolating them from environment.

EFFECT: enhanced temperature differential between cool and hot coolants.
