A mathematical model of the ongoing processes in a heat exchanger with heat pipes has been developed. The heat carrier is flue gas and the heated fluid is water. The numerical modelling is carried out by the CFD software SolidWorks – Flow Simulation. The obtained numerical results present the temperature and velocity fields in the heat exchanger. The influence of the heat exchanger’s design parameters over the temperature and velocity of the heated fluid are investigated. The modelled heat exchange has finned tubes thermosiphons in the evaporator zone and smooth tubes in the condensation zone. An analysis of the significant design parameters of the finned tubes over the heated fluid is carried out.
