Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive electric insulating coating film material excellent in heat resistance, heat transmittance and heat resistance strain characteristics in use at normal temperatures of 200-500 deg.C, in which an electric insulating coating film is formed at a heat treatment temperature of 500 deg.C or lower. SOLUTION: In a fabricating method, an electric insulating coating film material including a mixture 4 composed of composite glass powder containing water lass, PbO or the like and electric insulating powder is applied onto a metal substrate 2, followed by drying and heating, thereby causing a thermal oxidation reaction. Thus, an electric insulating coating film 7 consisting of an electric insulating oxide layer 5 and a glass-based coating film 6 is formed on the metal substrate.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of thermoelectric conversion characteristics caused by sublimation and oxidation, etc., of an element in PbTe, for example and attain stable thermoelectric conversion for a long period by crowning at least a high temperature side end part of a thermo-element with a conductive block having a recessed part in which the end part is force-fitted. SOLUTION: Since edge parts 1H and 1L of a thermo-element 1 are crowned with a conductive block 3, the end part can be electrically and thermally combined to other parts by the conductive block 3. The thermo-element 1 and the conductive block 3 are combined by force-fitting a thermo-element end part to the recessed part 1 of the conductive block 3. Since there is a possibility of generation of a gap between a thermo-element and a conductive block microscopically, generation of heat shearing stress can be avoided even if the high temperature side end part 1H is subjected to high temperature heating. Furthermore, it is possible to avoid generation of sublimation and oxidation of a constituent element of the thermo-element 1 and prevent variation of an element and deterioration of characteristics.

SOLUTION: A thermoelectric conversion element 31 consisting of a thermoelectric conversion material is sandwiched between metal segments 41 to 43 that face opposite to each other, and the metal segments 41 to 43 are connected to the thermoelectric conversion element 31 by a fixing screw 34. The through- hole of the fixing screw 34 is formed in the metal segments 41 and 42 that face opposite to each other, a through-hole 35 of the fixing screw 34 is formed at the center part of the thermoelectric conversion element 31, and furthermore a screw hole 37 for screwing to the tip of the fixing screw 34 is formed in the metal segment 43. Then, the fixing screw 34 is inserted into the through-hole of one of metal segments 41 and 42 and the through-hole of the thermoelectric conversion element 31, the tip part is screwed to the screw hole 37 of the segment 43, and the thermoelectric conversion element 31 is arranged between the metal segments which face opposite to each other for connection.

Abstract: PROBLEM TO BE SOLVED: To avoid the breakdown of each part and improve thermoelectric conversion property and reliability by constituting the heat conductive part of a thermoelectric conversion module out of a metallic plate or a metallic layer coated with a ceramic layer. SOLUTION: Heat conducting parts 26H and 26L are constituted of a metallic plate 28 or a metallic layer coated with a ceramic layer 27, so as to materialize electric insulation or good heat conduction between metallic segments 15A and 15B of a thermoelectric covering element 10 and heat conductive parts 26H and 26L. For example, after boring a through screw hole or the like in the required place of the metallic plate 28, the whole surface is flame-coated with Al2 O3 which is high in heat conductivity into a thickness in the range 10μm-50μm to coat it with a ceramic layer 27. Then, the heat conducting part 26H on high temperature side and the heat conducting part 26L on the cooling side made that way are fixed by fixing screws 18 such as insulating ceramic, teflon, or the like, so as to set up a thermoelectric conversion module.

Abstract: PROBLEM TO BE SOLVED: To enhance thermoelectric conversion characteristics by performing pressure deformation or extrusion plastic working of a fused or sintered thermoelectric semiconductor material while heating electrically. SOLUTION: A metal powder material 6 for one electrode of a thermoelectric conversion element, a sintered or fused mass of thermoelectric semiconductor material 5, and a metal powder material 6 for the other electrode are arranged sequentially on a punch 4 in the cavity 1 of a die 2. Punches 3, 4 are then pressed each other or one punch is pressed against the other thus compressing the powdery electrode material 6 and the semiconductor material 5. Under that state, a large current is fed between the conductive punches 3, 4 and hot working is performed. Alternatively, a punch 23 is pressed toward the outlet 24 of a die 22 to extrude the thermoelectric semiconductor material 5 while softening. In this regard, a large current is fed between the conductive punches 23, 22 to generate heat and the material is extruded by applying a pressure while controlling the working temperature.
