Abstract:

The object was to design, build, and test the heat rejection portions of a large 2-kwe radioisotope thermoelectric generator RTG. The design was optimized to produce the lowest practicable temperatures at the cold junction of a large number of thermoelectric heat-to-electricity conversion elements. The geometry was largely defined by the size, shape, and required number of thermoelectric elements and by their deployment at the upper end of a large pressure-resistant hull. The work showed the capability of the 12-finned convectors to maintain a temperature below 90F, at the inner face of the convectors both when the unit was vertical and when tilted 60 degrees from the vertical. The solid copper showed no signs of corrosion the potential corrosion problem is discussed in some detail in the report, as are related problems of flow, protection, and possible fouling from marine growth.
