A turbocharger including center housing with a thermally decoupling flange is
provided.
The flange, which extends generally radially outward from a body of the center
housing, has a connection portion that can be used to mount the center housing
to a turbine housing of the turbocharger. A curved portion of the flange is disposed
between the connection portion and the housing body and provides a thermal decouple
for reducing the thermal gradient in the connection portion. The curved portion
can also increase the flexibility of the flange to reduce the stresses therein
that result from temperature variations in the center housing.
