ABSTRACT:
A subsea thermoelectric generator has a plurality of flat thermoelectric modules attached concentrically to the outside wall of an undersea line in which petroleum products extracted from a subsea drilling well circulate. The thermoelectric modules are disposed in flat-bottomed pans machined into the outside wall of the line. The pans are sealed by lids made of heat-conducting material and in thermal contact with the thermoelectric modules. Each lid defines, with the walls of the corresponding pan, a peripheral sealed chamber. The various chambers in the pans communicate with each other through passages provided in partitions that separate the pans and are filled with a soft (compliant), preferably non-heat-conducting, resin. At least one of the pans is provided with an orifice closed by a sealed deformable element.
