Abstract: The present invention relates to a charge air cooling unit comprising a first charge air cooler having a first end face provided with a first cooling fluid inlet and a first cooling fluid outlet and a second charge air cooler having a second end face provided with a second cooling fluid inlet and a second cooling fluid outlet. Specifically, the second charge air cooler is arranged adjacent to the first charge air cooler such that the first end face and the second end face are oriented in the same direction. Further, the charge air cooling unit comprises a manifold unit connected to the first end face and the second end face for guiding a cooling fluid through the first charge air cooler and the second charge air cooler.

Abstract: A two-stage turbocharged internal combustion engine comprises a low-pressure stage turbocharger mounted at a first end side of an engine block and a high-pressure stage turbocharger mounted at the same first end side of the engine block. The respective turbochargers are mounted via a mounting structure, Which also accommodates the charge air coolers associated with the turbochargers. In order to obtain a compact arrangement and reduce a length of pipe connections between the different components, the different charge air coolers are mounted to mounting structure such that they overlap in a plan view of the internal combustion engine. Further, flow directions of charge air in the different charge air coolers are opposite to each other.
