Turbine housing with wall cladding

Abstract

A turbine housing for a turbine is provided. The turbine housing includes a wall cladding on an inner wall of the turbine housing. In a region of joint flanges, the wall cladding is arranged and embodied such that the wall cladding reduces convective heat transfer and thermal radiation in a region of the joint flanges.

1 .- 7 . (canceled) 
     
     
         8 . A turbine housing, comprising:
 a turbine housing lower part and a turbine housing upper part, each turbine housing part foaming a joint at a joining area when the turbine housing part are in an assembled state,   wherein each turbine housing part comprises a joint flange in a region of the joint, and wherein the turbine housing parts are screwed to one another by joint screws via the joint flanges; and   a wall cladding on an inner wall of the turbine housing, wherein the wall cladding is arranged and embodied in the region of the joint flanges such that the wall cladding reduces a convective heat transfer and a thermal radiation in the region of the joint flanges.
