Abstract

Die Wärmeaustauschleistung von Rohren (1) aus schwer formbaren metallischen oder aus keramischen Werkstoffen mit im wesentlichen glatten Innenoberflächen für Rohrbündelwärmeaustauscher wird verbessert, indem der Innenraum der Rohre mit einem strangförmigen Einsatz (4) versehen wird, dessen äußere Oberfläche mit in der Fluidströmung im Rohr Turbulenzen erzeugenden Profilierungen wie Wellen oder Noppen (6,12,13) versehen ist. Bevorzugte Einsätze sind Wellrohre aus chemisch resistenten und thermisch beständigen Kunststoffen.

Figure 00000001
The heat exchange performance of pipes (1) made of difficult to form metallic or ceramic materials with essentially smooth inner surfaces for shell-and-tube heat exchangers is improved by providing the interior of the pipes with a strand-shaped insert (4), the outer surface of which is turbulent in the fluid flow in the pipe generating profiles such as waves or knobs (6,12,13) is provided. Preferred uses are corrugated pipes made of chemically resistant and thermally resistant plastics.
