Exhaust gas housing of a thermal engine
In an exhaust gas housing ( 1 ) of a thermal engine, a radially outer housing casing ( 9 ) and a radially inner housing casing ( 10 ) arranged on the hub side are connected to one another via at least one thermally insulated carrying rib ( 3 ) acted upon by a cooling medium. A carrying rib ( 3 ) has...

| Zusammenfassung: | In an exhaust gas housing (
1
) of a thermal engine, a radially outer housing casing (
9
) and a radially inner housing casing (
10
) arranged on the hub side are connected to one another via at least one thermally insulated carrying rib (
3
) acted upon by a cooling medium. A carrying rib (
3
) has at least two passage ducts (
7
) and (
8
) for the cooling medium, at least one passage duct (
7
) possessing a cooling medium supply (
6
) and at least one passage duct (
8
) possessing a cooling medium outlet (
12
), and these passage ducts (
7
) and (
8
) being in communicating connection in the radially inner hub-side end region via a deflection duct (
11
). The cooling medium is led from an external pressure source (
5
) through the carrying rib (
3
) to the region of the deflecting duct (
11
) arranged on the hub-side casing (
10
) and from there through the carrying rib (
3
) back again into a collecting duct (
15
) which issues preferably into an annular duct (
26
) for cooling the exhaust gas housing flange (
24
). |
