Abstract
A heat exchanger for use with two media, one of which is to be heated up and the other of which is to be cooled down. The heat exchanger has an inlet and an outlet for the medium which is to be cooled down, as well as a plurality of parallel conduits which are connected between the inlet and outlet so that the medium flows through the conduits as it passes through the heat exchanger. The conduits are connected to each other such that the medium changes its direction of flow by 180.degree. at least once between the point where it enters the heat exchanger through the inlet and the point where it leaves the heat exchanger through the outlet.
