Abstract: A thermoelectric device may include a casing of tubular shape in which extends a plurality of modules of thermoelectric elements extending parallel to a longitudinal axis of the casing. Additionally, each module may include a plurality of thermoelectric elements having a cylinder or right prism shape with a central opening, a first fluid circulating through the central opening, and a second fluid circulating around the exterior periphery, and an enclosure capping said thermoelectric elements. Further, the enclosure may include at least an intake for the second fluid and a discharge for said second fluid. Furthermore, a number and dimensions of said thermoelectric element modules is optimized as a function of the ratio between a volume of the thermoelectric elements and a volume of the casing, a thickness of the enclosure and a distance between two adjacent modules.

Abstract: An assembly is formed of a plurality of tubes (1, 2) for circulating a fluid. The tubes (1, 2) extend parallel to one another. The assembly is further formed of a plurality of thermoelectric elements (3) making it possible to create an electric current from a temperature gradient applied between two contact surfaces (4a, 4b) thereof. The thermoelectric elements (3) are distributed over the tubes (1, 2) with which the thermoelectric elements (3) are in contact via one (4b) of their contact surfaces. The assembly is designed so as to enable the installation of tubes for circulating another fluid, with the tubes being intended to be in contact with the thermoelectric elements (3) via the other (4a) contact surface thereof and extending in a direction that is a secant relative to the direction of extension of the tubes (1, 2). A thermoelectric device is equipped with a stack of assemblies.
