    摘要： A heat exchanger, particularly an exhaust gas heat exchanger, for transferring heat in two stages between a first fluid and second and third fluids that have different temperatures includes a block for separately conducting the first and second and third fluids in a heat transferring manner. The block encompasses a number of ducts through which the first fluid can flow, a first chamber of a high-temperature part through which the second fluid can flow and which accommodates the ducts, a second chamber of a low-temperature part through which the third fluid flows and which accommodates the ducts, and a housing in which the first and second chamber as well as the ducts are arranged. The first chamber and the second chamber are separated from one another by a separation area that is mounted in a groove.

    摘要： A heat exchanger, particularly an exhaust gas heat exchanger, for transferring heat in two stages between a first fluid and a second and third fluid that have different temperatures is provided. The heat exchanger comprises a block for separately conducting the first as well as the second and third fluid in a heat transferring manner. The block encompasses a number of ducts through which the first fluid can flow, a first chamber of a high-temperature part, through which the second fluid can flow and which accommodates the ducts, a second chamber of a low-temperature part, through which the third fluid flows and which accommodates the ducts, and a housing in which the first and second chamber as well as the ducts are arranged. Thus, a two-stage heat exchanger is provided at a low cost and keeps leakage between the high-temperature part and the low-temperature part low. Whereby the first chamber and the second chamber are separated from one another by means of a separation area that is mounted in a groove.

    摘要： The invention relates to a system for using the waste heat of an internal combustion engine by means of the Clausius-Rankine cycle, wherein an incorporation of an operating medium into the combustion air fed to the combustion engine due to lack of sealing or a leak at the evaporator heat exchanger is substantially ruled out. Said aim is achieved, according to the invention, in that the at least one first flow channel is formed by at least one first limiting component and the at least one second flow channel is formed by at least one second limiting component and there is a fluid-conducting connection to the surroundings or to a receiving chamber from the at least one first limiting component and preferably from the at least one second limiting component, so that in the event of a leak at the at least one first limiting component the operating medium can be conducted into the surroundings or into the receiving chamber and preferably in event of a leak at the at least one second limiting component the fluid can be conducted into the surroundings or into the receiving chamber.
