Abstract: The present invention relates to a heat exchanger for a motor vehicle, including a plurality of plates, the plates being stacked on top of one another along a stacking axis so as to form a bundle of plates, at least a first plate and at least a second plate which define a first circulation path configured for circulation of a first fluid, at least the second plate and at least a third plate which define a second circulation path configured for circulation of a second fluid, the bundle of plates having a first distribution chamber which supplies the first circulation path with first fluid, and a second distribution chamber which supplies the second circulation path with second fluid. The heat exchanger includes at least one purification device arranged in one of the distribution chambers.

Abstract: The invention relates to a thermal management device for the thermal management of an electrical and/or electronic component liable to release heat during its operation, said device including a casing, said casing having a main compartment defining at least one housing able to accept said electrical and/or electronic component, said housing being designed to receive a dielectric fluid and being delimited by at least one wall. The wall includes a partition defining within the housing a first and a second chamber of dielectric fluid, said partition including an opening that is arranged in such a way that, when the electrical and/or electronic component is placed in the housing, this electrical and/or electronic component extends on both sides of said partition so that this electrical and/or electronic component extends into both of the two chambers.
