Cooling of the rotor and stator components of a turbocharger with the help of additively manufactured component-internal cooling channels

摘要

The invention relates to a turbocharger (1) with a turbine (2) and a compressor (3), each of which has a rotor (21, 31) and a stator (22, 32), with at least one of the respective rotors (21, 31 ) and / or stators (22, 32) have at least one internal flow channel (4), which is at least partially or completely surrounded by a wall (10), for cooling and wherein the respective rotor (21, 21), which has at least one flow channel (4). 31) and / or stator (22, 32) is at least partially manufactured by means of additive manufacturing. The invention also relates to a method for producing such a turbocharger (1).
