THERMOELECTRIC GENERATOR Russian patent published in 2007 - IPC H01L35/30 

FIELD: thermal-to-electrical energy conversion.

SUBSTANCE: proposed generator has heat load made in the form of variable-section monolithic heat-transfer plate. Attached to heat load by means of hold-down unit are thermoelectric batteries and heat sinks mounted symmetrically on effective sides of heat load. Hold-down unit is made in the form of bent stud threaded on both ends and passed via through holes in heat-sink base and in heat-transfer plate. Base of the latter is provided with semicylinder mounted so that its longitudinal axis is perpendicular to vertical symmetry axis of heat-transfer plate. Through hole of the latter receiving bracing stud is of rectangular section. Stud is made of material whose coefficient of thermal expansion is lower than that of generator mechanical design components being braced, Flexible heat transfer between heat-transfer plate and thermoelectric battery is made in the form of lead foil plated with tin on both sides.

EFFECT: improved design.
