Claim:
1. A heat exchanger for exchanging heat between at least two fluids being guided through the heat exchanger, the heat exchanger comprising: parallel plates connected to one another by connecting walls defining chambers which are provided with an inlet and an outlet, each in a connecting wall, which guide the fluid through the chambers, and wherein, in the chambers there is provided at least one guiding profile guiding the flow through the chambers according to a selected course which changes direction at least locally between the inlet and the outlet; wherein the at least one guiding profile comprises an extruded tubular profile having two parallel walls enabling the tubular profile to make contact with the parallel plates, said walls being connected to one another by two sidewalls and one or several dividing walls which internally divide the extruded tubular profile in two or several compartments extending in the extruding direction of the tubular profile, and wherein one or several fluid guiding passages are provided in the dividing walls and/or in the sidewalls, and wherein the at least one guiding profile is configured in a way such that the two parallel walls of the tubular profile contact, along an entire width of the tubular profile, the parallel plates defining the respective chambers and the two parallel walls of the tubular profile contact the respective chambers along an entire width of the inlet and/or the outlet of the chambers.
