THERMOELECTRIC GENERATOR Russian patent published in 1996 - IPC

FIELD: thermoelectric generators operating on liquid or gas fuel. SUBSTANCE: the assembly uses a heat-exchange unit with ducts for the heat- transfer agent, thermoelectric batteries located on the unit sides, and coolers adjoining the batteries. The interference-fit assembly is enveloped by a shell made of elastic material. The cooler central section projects with respect to its extreme areas. A plate spring is fastened between this section and thin-walled shell; the spring is bent during assembly and has a constant force of compression of its members. It is preferable to choose the relation between the shell thickness and plate spring thickness within 1:1.25 to 1:3. EFFECT: enhanced efficiency. 8 cl, 3 dwg
