Abstract
A heat exchanger comprised of individual plates has flow channels operating in parallel flow or counterflow. The flow channels for a first medium are defined between individual plates forming a pair and for the second medium are defined between the pairs that are arranged to form the heat exchanger stack. In order to distribute the inflowing medium within a short axial inflow area over the entire channel width, the individual plates are provided with guiding projections extending at least from one side of the plate into the respective flow channel. In order to improve the heat exchange efficiency, the individual plates have a profiling in the form of a plurality of individual protrusions arranged over the entire channel width and channel length for creating a flow turbulence in the flow channels.
