Beschreibung
Zusammenfassung:	A system includes a machine having an external surface and a shaft extending from a first side of the machine; a cooling airflow generator mounted on the shaft and operative to generate a cooling airflow for cooling the machine; a flow guide structure constructed to receive the cooling airflow from the cooling airflow generator and to direct the cooling airflow received from the cooling airflow generator across the external surface; and a scavenge scoop spaced apart from the flow guide structure and disposed at a second side of the machine opposite the first side, wherein the external surface is disposed between the scavenge scoop and the flow guide structure, and wherein the scavenge scoop is constructed to collect a portion of the cooling airflow generated by the cooling airflow generator and direct the a portion of the cooling airflow across a portion of the second side of the machine.
