Turbocharger
A turbocharger with a turbine for expanding a first medium and a compressor for compressing a second medium utilizing energy extracted in the turbine during the expansion of the first medium. The turbine comprises a turbine housing and a turbine rotor. The turbine housing is connected to a bearing housing. An inflow housing of the turbine housing is formed in a double-walled manner, namely of an inner flow-conducting core and an outer force-conducting shell.
1. A turbocharger, comprising:
a shaft;
a turbine configured to expand a first medium, comprising:
a turbine rotor;
a turbine housing, wherein the turbine housing is a double-walled inflow housing having an inner flow-conducting core that is undivided in the axial direction and an outer force-conducting shell, wherein the outer force-conducting shell is split into two halves in an axial direction;
a compressor configured to compress a second medium utilizing energy extracted in the turbine during expansion of the first medium, comprising:
a compressor housing; and
a compressor rotor that is coupled to the turbine rotor via the shaft; and
a bearing housing arranged between and connected to both the turbine housing and the compressor housing.
2. The turbocharger according to claim 1 , wherein a section of a first half of the outer force-conducting shell and a first section of the inner flow-conducting core are each at least one of: attached to the bearing housing and adjoin the bearing housing.
3. The turbocharger according to claim 2 , wherein a section of a second half of the outer force-conducting shell and a second section of the inner flow-conducting core are each at least one of:
attached to an insert piece of the turbine housing and
adjoin the insert piece of the turbine housing.
4. The turbocharger according to claim 3 , wherein the halves of the outer force-conducting shell have respective flanges by which the halves of the outer force-conducting shell are attached to one another.
5. The turbocharger according to claim 4 , further comprising:
a heat-insulating material arranged in a hollow space between the inner flow-conducting core and the outer force-conducting shell.
6. The turbocharger according to claim 1 , wherein the inner flow-conducting core is undivided in an axial direction.
7. The turbocharger according to claim 1 , wherein a section of a first half of the outer force-conducting shell and a first section of the inner flow-conducting core are each at least one of:
attached to the bearing housing and
adjoin the bearing housing.
8. The turbocharger according to claim 1 , wherein a section of a second half of the outer force-conducting shell and a second section of the inner flow-conducting core are each at least one of:
attached to an insert piece of the turbine housing and
adjoin the insert piece of the turbine housing.
9. The turbocharger according to claim 1 , wherein the halves of the outer force-conducting shell have respective flanges by which the halves of the outer force-conducting shell are attached to one another.
10. The turbocharger according to claim 1 , further comprising: a heat-insulating material arranged in a hollow space between the inner flow-conducting core and the outer force-conducting shell.
