Heat exchanger for a motor vehicle

A heat exchanger for a motor vehicle,

• the heat exchanger comprising:
• a first circuit configured to be traversed by a heat-transfer fluid,
• the first circuit comprising:
• a first inlet header through which the heat-transfer fluid is admitted into the first circuit, and
• a first outlet header through which the heat-transfer fluid leaves the first circuit,
• a second circuit configured to be traversed by a heat-transfer fluid, wherein the second circuit is fluidically separate from the first circuit and comprises:
• a second inlet header through which the heat-transfer fluid is admitted into the heat exchanger, and
• a second outlet header through which the heat-transfer fluid leaves the heat exchanger,
• wherein the first circuit or the second circuit comprises an additional header that extends in the same direction as the inlet headers and outlet headers of the first circuit and the second circuit,
• wherein the additional header is separate from the inlet and outlet headers,
• wherein the first and second circuits comprise a plurality of chambers linked fluidically to the inlet headers and outlet headers of either the first circuit or the second circuit respectively,
• wherein the heat exchanger comprises a first group of chambers and a second group of chambers,
• wherein the first group of chambers is separated from the second group of chambers by at least one deflecting plate configured to force the fluid of at least the first circuit or the second circuit to flow in a first flow direction in the first group of chambers and to force the fluid to flow in a second flow direction in the second group of chambers,
• wherein the inlet headers of the first and second circuits each comprise a supply channel configured to supply heat-transfer fluid to the first circuit or the second circuit respectively,
• wherein the outlet headers of the first and second circuits each comprise an outlet channel configured to drain heat-transfer fluid from the first circuit or the second circuit respectively, and
• wherein the supply channels and the outlet channels are positioned on a same face of the heat exchanger.
