The company also has experience in thermoelectric technology which is used in submarines for cooling systems. In light of this experience, DCN CHERBOURG was contacted by an oil company in order to develop a thermoelectric generator for an offshore subsea application The requirements were: (i) a thermogenerator able to be inserted as a spool in a submarine pipeline; (ii) site: North Sea (sea water temperature=4/spl deg/C); and (iii) fluid: mix of oil and gas, temperature between 90/spl deg/C and 120/spl deg/C, pressure 450 bar. The design began with thermoelectric module tests (electrical, thermal and mechanical). The objective was to select the type of thermoelectric module and the assembly system. The ceramic technology from MELCOR was chosen. DCN CHERBOURG then made and tested a prototype. The performance results were not as good as expected, however, the prototype proved that a thermoelectric generator for an offshore subsea application was feasible. The next step was the assembling of two thermogenerators (THEGS) for an offshore application. The performance measurements obtained during on-shore testing were as expected: about 100 W at 70 V.","PeriodicalId":174813,"journal":{"name":"XVI ICT '97.

Although single crystals of CoSb/sub 3/ have high electrical conductivities and moderate Seebeck coefficients, the ZT values are relatively low because of the high thermal conductivities. We tried to lower the thermal conductivity of hot-pressed CoSb by reducing the grain size. Mechanical alloying of the raw material powders of Co and Sb was the very effective method to reduce the grain size of hot-pressed CoSb/sub 3/. This paper shows the relations between the thermoelectric properties (Hall mobility, Seebeck coefficient, electrical conductivity and thermal conductivity) and the grain size. The thermal conductivity of hot-pressed CoSb/sub 3/ decreased with reducing the grain size. The value of 4.19 Wm/sup -1/ K/sup -1/, which is about 40% of the single crystals, was ultimately obtained at 293 K for the hot-pressed material with an average grain size of 0.9 /spl mu/m. Although the larger grain size is preferable to attain a high ZT value at 293 K, because of the greater decrease of the carrier mobility than the thermal conductivity with reducing the average grain size, the highest ZT value of 0.10 was obtained at 673 K on the sample with an average grain size of 2.1 /spl mu/m.","PeriodicalId":174813,"journal":{"name":"XVI ICT '97.
