IC engine exhaust turbocharger - has shaft with heat tube to transfer heat from turbine to compressor rotor

摘要

The exhaust gas turbocharger is partic. for mixture-compressing automotive engines, having a compressor rotor rigidly coupled by a shaft to a turbine rotor. The shaft (5) incorporates means (11) to transfer heat from the turbine rotor (3) to the compressor rotor (4), typically a heat tube concentrically mounted in the shaft, and with a capillary structure (12) running for the entire length along the outside wall, or alternatively only near the turbine rotor, which is vertically below the compressor rotor.
