| 摘要 |
Thermoelectric generator includes a chamber containing radioactive nuclides as heating source and surrounded by thermocouple elements formed of respective pairs of thermocouple element legs having a hot side facing toward and a cold side facing away from the chamber, and shielding means comprising a pair of telescoped hollow members fully surrounding the chamber, the thermocouple element legs being located in the interior of the inner hollow member of the telescoped pair at locations thereof whereat the walls of the hollow members overlap, the respective pairs of thermocouple element legs being connected at their cold side by a contact bridge which is firmly connected mechanically to the wall of the inner hollow member so that the walls of the hollow members serve as heat exchanger for the cold side of the pairs of thermocouple element legs.
