Abstract: An assembly of at least one thermoelectric element capable of generating an electric current under the effect of a temperature gradient exerted between two of its sides, referred to as the contact sides, and an electrical connection means is disclosed. The assembly includes a first deformable element electrically connecting the electrical connection means to the thermoelectric element, the first element including a first side linked to the electrical connection means and a second side linked to the thermoelectric element, the first side being deformable independently from the second side and vice versa, the assembly including a second deformable element forming a heat bridge between the first and second sides of the first element. A thermoelectric module including such an assembly and a thermoelectric device including such a module are also disclosed.

Abstract: A thermoelectric module (20) includes at least one thermoelectric element (3) having at least one opening (10) designed to be in a thermal relationship with a hot fluid. The thermoelectric element (3) has an active face designed to be in a thermal relationship with a cold fluid of a temperature lower than that of the hot fluid. The thermoelectric element (3) is designed to generate an electric current under the action of a temperature gradient applied by the hot fluid and the cold fluid between the opening (10) and the active face of the thermoelectric element. The opening includes two circuits (41, 42) for circulating the hot fluid, a first circuit (41) in contact with the thermoelectric element (3) and a second circuit (42) positioned within the first circuit (41).

Abstract: The invention relates to a thermoelectric element comprising at least one opening and a set of apertures. The opening is designed to be in a thermal relationship with a hot source, and the apertures are designed to be in a thermal relationship with a cold source that is of a temperature that is lower than that of the hot source. The thermoelectric element is designed to generate an electric current under the action of a temperature gradient applied by the hot source and the cold source between the opening and the apertures. The invention also relates to a thermoelectric module comprising at least one thermoelectric element.
