Intake manifold for a supercharged internal combustion engine with a built-in intercooler and provided with a heat exchanger for a high-pressure EGR circuit

Intake manifold (4) for a turbocharged internal combustion engine (1) provided with a compressor (14) and a high-pressure gas recirculation branch (EGR HP ) ; the intake manifold (4) is provided with a central body (31) fed with a flow of air coming from the compressor (14) which houses, on the inside, a first air/water heat exchanger (9) to cool the air flow coming from the compressor (14); and a second air/water heat exchanger (21) to cool a flow of air in the high-pressure gas recirculation branch (EGR HP ); wherein the first heat exchanger (9) and the second heat exchanger (21) are in hydraulic communication so that the water used to cool the air flow coming from the compressor (14) is subsequently used to cool the air flow of the high-pressure gas recirculation branch (EGR HP ).
