Patent ID: 8365526

Claim:
A vehicle or stationary power plant having an internal combustion engine as a drive source and having components that are to be supplied with heat from a medium accommodated in a closed medium loop, comprising: an exhaust gas turbocharger for turbocharging said internal combustion engine, wherein said exhaust gas turbocharger includes a turbine having a turbine housing and acting as a heat source; and a heat exchanger having a housing, said heat exchanger having an external wall area that is disposed directly on an external wall of said turbine housing as an integral component of the turbine, wherein said external wall area of said heat exchanger is shaped to correspond to said external wall of said turbine housing and a further external wall cast or attached to said external wall of the turbine housing in a close-fit manner such that no space exists between said external wall area of said heat exchanger and said external wall of said turbine housing, wherein said heat exchanger is incorporated in said medium loop, wherein said medium is to be conveyed directly or in a channeled manner through an interior of said heat exchanger, wherein in said interior of said heat exchanger said medium is to be heated up utilizing at least thermal radiation energy from said turbine housing, and wherein said heat exchanger has a first connection connected to a supply line for said medium that is to be heated and a second connection that is spaced from said first connection, wherein a discharge line for heated-up medium is connected to said second connection, wherein a heat exchanger pipe extends between said first connection and said second connection of said heat exchanger or wherein a heat exchanger pipe bundle extends between two terminal collection chambers, wherein the medium to be heated is conducted through said heat exchanger pipe or heat exchanger pipe bundle in a channeled or piped manner.
