A combined heat exchanging and fluid mixing apparatus including a first conduit () for guiding a cool fluid through the first conduit and a second conduit () for guiding a hot gas through the second conduit. A heat conductive element () is arranged between the first conduit () and the second conduit () for transferring heat from the hot gas to the cool fluid. The apparatus further includes a third conduit () for guiding an exhaust fluid. The third conduit () comprises an exhaust fluid inlet () for introducing an exhaust fluid into the apparatus for mixing of the exhaust fluid with the hot gas and for a chemical reaction of the so formed exhaust fluid/hot gas mixture in the second conduit ().

Combined heat exchanging and fluid mixing apparatus

The heat exchanger includes a cool conduit (), a hot conduit () and a heat exchanging element () arranged between the cool conduit () and the hot conduit (). The heat exchanger also includes at least one further conduit () arranged next to the cool conduit () or to the hot conduit () on a same side of the heat exchanging element () as said respective cool or hot conduit. The further conduit is separated from the respective cool or hot conduit by a separator () that includes two separating elements () arranged at a distance to each other and forming a cavity () between the two separating elements (). The separator restricts a fluid flow into or in the cavity () such as to limit a heat exchange between the further conduit () and the respective cool or hot conduit on the same side of the heat exchanging element ().

Multi-flow heat exchanger for exchanging heat between cool fluid and hot fluid

A unit for recovering thermal energy from exhaust gas of an internal combustion engine including an inlet, an outlet, a heat exchanger arranged downstream of the inlet and upstream of the outlet, and a valve capable of being switched between a recovery position. The exhaust gas flows from the inlet through the heat exchanger to the outlet, and a bypass position, in which the exhaust gas flows from the inlet through a bypass to the outlet. The valve includes separate first and second valve bodies and associated separate first and second valve seats arranged upstream and downstream of the heat exchanger, respectively. The first and second valve bodies are adapted to be switched only simultaneously from the recovery position to the bypass position and vice versa.
