THERMOELECTRIC MODULE Russian patent published in 2021 - IPC H01L35/30 

FIELD: physics.

SUBSTANCE: thermoelectric module includes thermoelectric elements with p- and n-type branches, switching current-conducting plates electrically and mechanically rigidly connected to end surfaces of thermoelement branches to form common electric circuit, electrically insulating hot and cold heat transitions, said heat pipelines are rigidly located between switching plates and inner sides and at opposite outer sides of heat lines. Heat transitions are made in form of layer of metal oxide formed on inner surface layer of each of heat conductors. Heat transitions are made in the form of layers of metal oxide of heat conductors. On all electrical insulating heat transitions located on two sides of heat lines, an impregnating layer of dielectric material is applied uniformly along the entire surface, made in form of a two-component mechanical mixture of dielectric liquid and filler made from fine solid dielectric material. Filler used is steatite of composition Mg₃[SiO₁₀](OH)₂. FIller may contain a mechanical mixture of steatite with metals in proportion by weight of 8–10 % of metal, the rest - steatite. Dielectric liquid used to make the multicomponent mechanical mixture with the filler is toluene.

EFFECT: invention relates to direct energy conversion using Peltier effect or Seebeck effect.
