Claims
- 1. A turbine housing comprising:
an integral exhaust outlet conduit wherein the integral exhaust outlet conduit holds an inner conduit layer comprising woven wire, glass, metal foam, ceramic foam, ceramic particles, and/or metal particles.
- 2. The turbine housing of claim 1, further comprising an innermost conduit layer comprising perforated metal.
- 3. The turbine housing of claim 1 housing a turbine wheel and wherein the integral exhaust outlet conduit has a proximal end positioned proximate to the turbine wheel.
- 4. The turbine housing of claim 3, wherein the inner conduit layer has a proximal end positioned proximate to the turbine wheel.
- 5. The turbine housing of claim 1, wherein the inner conduit layer is positionable within the integral exhaust outlet conduit.
- 6. An exhaust conduit to receive exhaust from a turbine, the exhaust conduit comprising:
an inner conduit layer comprising woven wire, glass, metal foam, ceramic foam, ceramic particles, and/or metal particles; and an outer conduit layer for housing the inner conduit layer and connecting the exhaust conduit to a turbine.
- 7. The exhaust conduit of claim 6, wherein the exhaust conduit connects directly to the turbine.
- 8. The exhaust conduit of claim 6, wherein the turbine comprises a turbine housing and a turbine wheel and the exhaust conduit connects directly to the turbine housing.
- 9. The exhaust conduit of claim 6, wherein the inner conduit layer comprises woven wire.
- 10. The exhaust conduit of claim 6, wherein the inner conduit layer resides between an innermost conduit layer and the outer conduit layer.
- 11. The exhaust conduit of claim 10, wherein the innermost conduit layer comprises a perforated material.
- 12. The exhaust conduit of claim 6, further comprising connection means for connecting the exhaust conduit to the turbine.
- 13. The exhaust conduit of claim 12, wherein the connection means comprises a flange, a thread, one or more blades, and/or a compression fitting.
- 14. The exhaust conduit of claim 6 capable of withstanding temperatures equal to or greater than approximately 1000 F. (538 C.).
- 15. The exhaust conduit of claim 6, wherein the exhaust conduit reduces noise having frequencies greater than approximately 5,000 Hz at a temperature greater than approximately 1000 F. (538 C.).
- 16. The exhaust conduit of claim 6, wherein the inner conduit has a thickness determined, at least in part, by a turbine blade pass frequency.
- 17. The exhaust conduit of claim 6, wherein the inner conduit has a thickness determined, at least in part, by one or more frequencies and one or more exhaust temperatures.
- 18. The exhaust conduit of claim 6, wherein the turbine is part of a turbocharger.
- 19. An exhaust conduit for receiving exhaust from a turbine, the exhaust conduit comprising:
a first inner conduit layer comprising perforated steel; a second inner conduit layer comprising woven wire; and an outer conduit layer to hold the first inner conduit layer and the second inner conduit layer and to connect the exhaust conduit to the turbine.
- 20. The exhaust conduit of claim 19, wherein the exhaust conduit connects to the turbine via a compression fitting.
- 21. The exhaust conduit of claim 19, wherein the outer conduit layer fits into an exhaust outlet of the turbine.
- 22. The exhaust conduit of claim 19, further comprising a heat shield.
- 23. The exhaust conduit of claim 19, wherein the heat shield comprises woven wire.
- 24. The exhaust conduit of claim 16, wherein the outer layer comprises corrugations.
