FIELD: electricity.
SUBSTANCE: thermoelectric constructive element (1) has at least one coated by thermoelectric material (3) fiber (4). Thermoelectric constructive element (1) is annular. The method includes providing at least one fiber (2), coating at least one fiber (2) by thermoelectric material (3), so as to form at least one coated fiber (4), twisting at least one coated fiber (4) in a ring (5) with the central axis (6), compression of the ring (5) for obtaining thermoelectric constructive element (1) having a first length (7) in the axial direction (8), and separating the resulting thermoelectric constructive element (1) into several thermoelectric constructive elements (1), each of which has an axially (8), a second length (16), which is less than the first length (7). Pressing on the step is carried out at a temperature of at least 250°C, and a pressure of at least 2 bars. Thermoelectric constructive element (1) has at least one coated by thermoelectric material (3) fiber (4), wherein thermoelectric constructive element (1) is annular. At least one coated fiber (4) extends in the circumferential direction (9) in an angular range (10) of at least 120°.
EFFECT: increase of the durability of thermoelectric constructive element and resistance to alternating thermal stresses.
