Abstract: 1,095,744. Thermoelectric devices. SIEMENS A.G. Nov. 29, 1966 [Nov. 30, 1965], No. 53486/66. Heading H1K. In a thermoelectric device, such as a Peltier cooling element or thermoelectric generator, oxide layers 1a, 2a having glazed surfaces 1b, 2b insulate metal carrier plates 1, 2 from metallic bridges 5 which link the thermoelectric elements 3, 4. In the form shown the elements 3, 4 are P- and N-type semi-conducting blocks. Aluminium oxide layers 1a, 2b are produced on the aluminium plates 1, 2 by electrolytic oxidation, the glaze 1b, 2b subsequently being applied by flashing on a sprayed or painted slip of pulverized lead borate glass with silicate addition and water or alcohol. Various other glaze materials are suggested. The bridges 5 may be formed by flashing on a paste of silver, copper, nickel, gold, platinum or palladium with additives of mercury, indium, galium or tin to lower the flash temperature. The plates 1, 2 complete with the insulation and metallic bridges 5, are then dipped into a lead/tin/ bismuth solder, only the bridges 5 accepting the solder, and the elements 3, 4 are soldered thereto, their ends having first been coated with the same solder, or with pure bismuth. The glaze surface may be roughened to improve the contact with the bridges 5, this being achieved by the addition of aluminium oxide or silica to the glaze slip. The contact bridges 5 may, in an alternative embodiment, merely bear against the glazed insulation under pressure.
