A plate heat exchanger comprises a package of heat exchanger plates, each with a peripheral portion and several aligned through flow ports. The plates are permanently joined to form flow passages for two heat exchange media. First inlet and outlet channels communicate with every other flow passage, while second inlet and outlet channels communicate with the remaining passages. First guiding ribs in the port portions distribute the first heat exchange medium, and second guiding ribs do the same for the second medium. Fins in the heat exchange portion create parallel guide channels for both media. A mixing zone is configured between the fins and guiding ribs to equalize volume flow before entering the guide channels. Outermost guiding ribs prevent bypass flow between the plates and fins, ensuring efficient heat exchange.
