Air system for an internal combustion engine with an improved cooling power electronics of an electric auxiliary compressor assembly through the intake passage

摘要

An air system (1) for an internal combustion engine with an auxiliary compressor arrangement, wherein the air system (1) • an intake passage (2) adapted to supply air to a combustion chamber (3), • an auxiliary compressor (4) adapted thereto Aspirating air from the intake duct (2) and re-emitting compressed air into a pressure duct (9), • an electric motor (5) driving the auxiliary compressor (4), • power electronics (6) adapted to the electric motor (5) to control, • a support plate (7) on which the power electronics (6) is arranged comprises, wherein the carrier plate (7) the power electronics (6) to the intake passage (2) thermally connects, wherein the intake passage (2 ) serves as a heat sink and the intake passage (2) has a connection region (21) in which the thermal connection of the support plate (7) with the intake passage (2) is formed, wherein in the connection region (21) of the intake passage (2) at least one R ippe (30) in the interior of the intake passage (2) is formed.
