A heat exchanger (l) comprises a plurality of superimposed modular elements (2), by means of which at least three pluralities of passages (12, 13, 14) which are separate from each are formed in the heat exchanger, each of the pluralities of passages being in thermal contact with at least two of the other pluralities of passages, and a gas, a coolant fluid and a heat-carrying substance in the fluid are made to flow through respective pluralities of the three pluralities of passages. |
