THERMOELECTRIC MODULE AND METHOD OF ITS MANUFACTURING Russian patent published in 2008 - IPC H01L35/28 H01L35/34 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of thermoelectric instrument-making. The substance is as follows: thermoelectric module consists of semi-conducting thermocouples of "p" and "n" conductivity types, which are coated with a thin layer of electrically strong insulator and glued in matrix. At the end of thermocouples circuit there are two dielectric elements that have metallization on two facets. Metallization is connected to one of module current leads and one of the last thermocouples in the circuit. During module manufacturing, electrically strong insulator is applied to plates of "n" and "p" type conductivity, and the plates are further glued in three units. In the first unit equal number of "n" and "p" type are glued in alternating order. The second unit contains number of plates of "p" type less by one and dielectric bar with metallization of two facets. The third unit contains number of plates of "n" type less by one compared to the first unit, and dielectric bar with metallization of two facets. Units are cut in plates direction perpendicular to layers, then coated with electrically strong insulator, and the matrix is glued. Matrix includes even number of plated from the first unit, half of which is turned and installed next nearest. One plate, which is obtained by cutting the second and the third units, is glued to both edges. Matrix facets are polished. Thermocouples and dielectric elements metallization are commuted by formation of switching busbars on matrix facets. Dielectric plates with current lead installed in one of them are glued to matrix facets. Metallization of dielectric elements is commuted with current leads.

EFFECT: provides high density of thermocouples, efficiency and reliability of module.
