Zusammenfassung:Heating or cooling apparatus for a turbo-machine housing collar (1), that, in order to adjust the diameter of the housing, uses chambers (7, 8, and 9) that are arcs of a circle through which the gas is blown onto the ribs (6) of the housing (1). According to the present invention, the gas circulates in a counterflow direction or in alternate directions for adjacent chambers in order to equalize the blowing conditions at every point of the ribs.
