THERMOELECTRIC BATTERY Russian patent published in 2020 - IPC H01L35/30 

FIELD: electricity.

SUBSTANCE: invention relates to direct conversion of thermal energy to electric energy, namely, to design of an electric generating thermoelectric battery (TEB) equipped with sealed protective cover, which protects thermoelement materials from interaction with atmospheric oxygen. Essence: TEB includes protective cover consisting of heat-absorbing (hot) semi-paired rigidly interconnected and heat-removing (cold) half-case with hermetic outlets and pumping exhaust tube with thermocells placed inside the cover, electrically connected to each other in thermo-battery or thermal battery unit, and separated from internal surfaces of hermetically connected semi-covers with electrically insulating heat transitions. Hot semi-shell is made in the form of a set of several flat non-deformed plates of rectangular shape. Medium reinforcing plate of larger height (thickness), at least by order of extreme hot half-poured plates along length and width corresponds to size of thermopile or unit of thermobatteries arranged inside cover. Two extreme plates, upper and lower, are equispaced from lateral sides of the thermobattery by cantilever projections (shelves), into the internal gap between which along the entire perimeter a spacer is introduced. Spacer is made in form of solid four-sided frame, which on outer sides is equal to dimensions of flange of hot and cold semi-cases, and on inner size forms a gap on all four sides with its middle reinforcing plate. Depth of cold hollow-case punching makes 0.8–0.95 of TEB height.

EFFECT: technical result is increase of TEB reliability and efficiency.
