NOVELTY - The thermoelectric generator for supplying power to an electrical or electronic apparatus (14) by use of a heat source, comprises a set of aggregates (10) connected in parallel, where each aggregate contains a set of thermocouples connected in series. The number of aggregates and the number of thermocouples in aggregates are determined so as to adapt the impedance of the generator to that of the apparatus and to increase the voltage and the power supplied to the apparatus.    USE - In thermoelectric generators which can be used for supplying power to electrical or electronic apparatus by utilizing heat sources.    ADVANTAGE - The generator comprising n identical aggregates in parallel has n times lower internal resistance than that of one aggregate, which results in higher voltage and power supplied to the apparatus. In the case of an apparatus having the internal resistance of 16 Ohm, and the generator comprising 550 thermocouples connected in series giving an open-circuit electromotive force of 9 V, the voltage on apparatus is 1 V, and the supplied power is 0.06 W. In the case of the generator comprising 3 aggregates, connected in parallel, each containing 184 thermocouples, the open-circuit electromotive force is 3 V, the voltage is 1.5 V, and the supplied power is 0.15 W.    DETAILED DESCRIPTION - The thermocouples are formed by electroconducting wires of two different kinds, connected in series and subjected to a temperature difference between a heat source and a heat sink. The wires of thermocouples are determined so as to optimize the thermal resistance and the electrical resistance of the wires. The junctions (34) of wires of thermocouples are associated with radiators or other means for the heat exchange between the heat source and the heat sink. The aggregates of thermocouples are formed by a continuous wire (36) constituted of sections of wires of two different kinds connected end to end, by winding on a support made of material resistant to high temperatures, or by interlocking with a network of wires made of dielectric material also resistant to high temperatures. The manufacturing equipment comprises the means for supplying the electroconducting wires of two different kinds, the means for cutting to sections of predetermined length, the means for soldering the sections, and the means for guiding to form a succession of aligned and advanced sections, so that the sections of first wire are in alternation with the sections of second wire. The sections of wires are soldered end to end, and configured so that the junction of sections are on two sides of the aggregate. The means for supplying wires comprise dies with input of wires from reels or analogous equipment, to give wires a predetermined diameter. The manufacturing equipment also comprises means for depositing a dielectric coating on continuous wire obtained at the output of soldering stage. The configuration means comprise the means for winding on a support (56), or the means for interlocking with the use of continuous wire as the frame wire in a network of electroinsulating wires, e.g. of fibre glass.
