The invention relates to a method for manufacturing a thermoelectric device, comprising a first circuit (), called hot circuit, through which a first fluid can flow, and a second circuit (), called cold circuit, through which a second fluid can flow at a temperature lower than that of the first fluid, elements (), called thermoelectric elements, that can be used to generate an electric current in the presence of a temperature gradient, fins () in a heat exchange relationship with said hot circuit () and/or said cold circuit (), the thermoelectric elements () being in contact at least with said fins (). According to the method according to the invention, said fins () are compressed in order to ensure that said thermoelectric elements () are held against said fins ().

Method for manufacturing a thermoelectric device, especially intended to generate an electrical current in an automotive vehicle

The invention relates to a device () for channeling a stream of feed gas for an internal combustion engine, said device () being able to be installed at least facing an exchanger () for the thermal conditioning of the stream of gas, the device comprises a first canal (), referred to as central canal, for the circulation of the stream of gas, delimited by a first part () of a wall () and intended to channel the stream of gas toward a first zone () of a face () of the exchanger (), said device comprising at least one second canal (), referred to as lateral canal, for the circulation of the stream of gas, delimited by a second part () of the wall () and intended to channel the stream of gas toward a second zone () of said face () of the exchanger (). The invention also relates to an intake airbox of an internal combustion engine and to an air inlet box of said airbox equipped with such a device. It further relates to an air intake module of an internal combustion engine comprising such an airbox.

Device for channeling a flow of feed gas for an internal combustion engine

The invention relates to a method of manufacturing a thermoelectric device comprising a plurality of thermoelectric components () for creating an electric current from a temperature gradient applied between two faces () thereof. In the method, a thermally conductive support () is provided in contact with a hot or cold source, a thermally conductive and electrically insulating material is thermally sprayed on the support () to produce a coating (), and an electrically conductive material is thermally sprayed onto the coating () to form electric conduction tracks () which are intended to receive the thermoelectric components () via the faces () thereof. The invention also relates to a thermoelectric device obtained by the method.
