Abstract
The heat exchanger having a heat exchanging channel () comprises an inlet () and an outlet () for a medium flowing through the heat exchanging channel. The heat exchanger has at least two stages () being arranged one after the other in view to the flowing direction of the medium, each stage having a heat exchanging channel (). The first stage has at least one guiding channel () arranged parallel to the heat exchanging channel (). The heat exchanging channel () has at the end of the respective stage () at least one outlet () and the guiding channel () of the respective stage is connected with the heat exchanging channel () of the next following stage (). By this unused heat transfer medium is fed to each stage, said heat transfer medium having a higher temperature difference with respect to the respective heat exchanging channel. By this a good heat transfer efficiency is realized even with relatively long flow pathes.
