Zusammenfassung:A compressor section includes a compressor wheel and a compressor housing that surrounds the compressor wheel. The compressor housing includes a flow passage with an upstream area. The compressor section also includes a cooling pocket that is defined within the compressor housing. The cooling pocket is configured to receive a coolant for cooling the compressor housing. Furthermore, the compressor section includes a thermo-decoupling pocket that is defined within the compressor housing. The thermo-decoupling pocket is disposed between the cooling pocket and the upstream area of the flow passage. The thermo-decoupling pocket is fluidly connected to an exterior area outside the compressor housing and/or fluidly disconnected from the flow passage.
