Turbocharger system and method of controlling heat transfer.

摘要

A turbocharger system including turbine housing (28) and compressor housing (34) sections which are connected by a centre housing section (14). The centre housing section journals a shaft (20) carrying a compressor wheel (24) and a turbine wheel (22) rotatable in the respective housing sections. The centre housing section also defines a closed cavity (50) captively receiving a material (52) which both conducts heat and changes phase during hot soak of the turbocharger following engine shutdown to control bearing temperatures at the shaft (20).
