Abstract
The present invention relates to a turbine housing (1) having an inner housing (2) which is surrounded by an outer housing (3), the inner housing (2) and the outer housing (3) each having a first, upper partial region (5) and a second, lower partial region (6), and having an inner-housing outer surface (7) and an outer-housing inner surface (8) which are positioned opposite one another, with a distance between them. At least in a part of the first partial region (5), the inner-housing outer surface (7) has a lower heat transfer through radiation to the opposite outer-housing inner surface (8) than at least in a part of the second partial region (6) of the inner-housing outer surface (7). This can be achieved by means of suitable surface coatings in the respective regions which have different absorption and/or emission coefficients (a1, a2). The result is a temperature compensation between the upper side and the lower side of the corresponding housing (2, 3), so that distortion of the housing during cooling is avoided.
