AUTONOMOUS PORTABLE THERMOELECTRIC POWER SOURCE Russian patent published in 2018 - IPC H01L35/28 

FIELD: electrical engineering.

SUBSTANCE: invention relates to thermoelectric power supplies. Autonomous portable thermoelectric power source includes a thermoelectric device that converts heat into electricity, a heat source in thermal contact with the heated side of the thermoelectric device, a heat exchanger in thermal contact with the cooled side of the thermoelectric device, accumulator of electric energy. Heat source contains a fuel element consisting of substances between which self-propagating high-temperature synthesis can occur. In the thermal contact with the heated side of the thermoelectric generator is a heat conductor. Power source also comprises a heat insulator, which directs heat from the fuel element towards the heat conductor, and from the heat conductor to the thermoelectric device, and the initiator of self-propagating high-temperature synthesis in the fuel element.

EFFECT: operation in an autonomous mode at small dimensions without the use of an external source to produce heat, which makes it possible to use the source in any ambient conditions.
