TUBE-AND-FIN HEAT EXCHANGER ABSTRACT A tube-and-fin heat exchanger comprising tubes for the flow of a heat carrier at some temperature, said tubes being installed in broached holes provided in a stack of fins. The tubes are installed so that adjacent fins form a multiplicity of ducts for the flow of another heat car- rier at a different temperature. Each fin is provided with productions and depressions which form in the ducts sym- metrical divergent-convergent portions for setting up tur- bulence in the heat carrier flow layer at the wall. The fins have rectilinear portions located between the diverg- ent-convergent portions and situated opposite each other on adjacent fins.
