Embodiment Construction

[0026] Such as Figure 1a As shown in , the invention relates to a heat exchanger, in particular for a motor vehicle, comprising a tube bundle 1 which, in a first function, allows the exchange between a first hot fluid and a second cold fluid heat exchange. The exchanger according to the invention is therefore intended to receive at its inlet two fluids, the first or hot fluid having a higher temperature than the second or cold fluid.

[0027] The hot fluid may be cooling fluid from the vehicle's engine cooling circuit, while the cold fluid may be the flow of ambient air from the front of the vehicle through its radiator. However, other types of fluids are feasible, in particular other types of thermal fluids. In particular, it may be a thermal fluid whose passage passes over the front faces of the vehicle in order to allow their cooling and / or phase change.

[0028] The exchanger is particularly configured such that the hot fluid passes through the hot fluid in a first dire...

Abstract

The invention relates to a thermoelectric module (10), in particular for a motor vehicle, including thermoelectric elements (15) enabling an electric current to be generated in the presence of a temperature gradient, and a heat-exchange device (20) through which a fluid is intended to flow, said device including a first surface (21) in a heat-exchange relationship with a first series of said thermoelectric elements (15), a second surface (22) in a heat-exchange relationship with a second series of said thermoelectric elements (15), and a means (25) for exchanging heat with the fluid, which means is in a heat-exchange relationship with said first and second surfaces (21, 22). The invention also relates to a heat-exchanger including such a thermoelectric module (10).

Description

technical field [0001] The invention relates to a thermoelectric module, in particular a thermoelectric module intended to form part of a heat exchanger. Background technique [0002] Thermoelectric modules have been proposed using thermoelectric elements that allow the generation of electrical current in the presence of a temperature gradient between two of their opposing faces, using a phenomenon known as the Seebeck effect. These modules comprise a tube bundle formed of stacked first tubes intended for the circulation of engine exhaust gases and second tubes intended for the circulation of a heat transfer fluid in the cooling passage. The thermoelectric elements are clamped between the tubes to be exposed to temperature gradients caused by the temperature difference between the hot exhaust gas and the cold cooling fluid. [0003] Such modules are particularly useful as they allow the conversion of heat caused by engine exhaust to generate electricity. They thus offer th...
