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

FIELD: engineering of thermo-electric batteries.

SUBSTANCE: thermo-electric battery consists of alternating branches, serially connected in electric circuit by means of commutation plates, which branches are made respectively of semiconductor of p-type and n-type. Electric connection of branches is realized by means of contact: p-type branch - commutation plate - n-type branch, where p-type branch contacts by its end-surface one of surfaces of commutation plate, and n-type branch - another one. Each branch in thermo-electric battery contacts two commutation plates by opposite end surfaces. Commutation plates have through apertures, made in mutually perpendicular planes. Apertures of all commutation plates by means of electro-isolating pipelines are joined in unified channel, along which during functioning of thermo-electric battery heat carrier flows. Channel is formed in such a way, that firstly by means of electro-insulating pipelines all apertures in even(odd) commutation plates are connected, and then, also serially - all apertures, made in odd (even) commutation plates. Between apertures, serially connected by electro-isolating pipelines, in even(odd) commutation plates and apertures in odd(even) commutation plates, an area for mating channel with heat carrier to freezing object is provided. Thermo-electric battery and pipelines are isolated from environment due to thermal isolation.

EFFECT: increased temperature drops due to operation in regenerative mode.
