Abstract

The device has a heat exchanger with plate-like heat delivery fluid channels (24, 25) formed by a double pipe. A heat transport fluid counter flows against a heat delivery fluid. A larger surface inner side of an outer flow chamber of the double pipe and a larger surface inner side of an inner pipe are profiled with steel belts running transverse to flow directions of fluids. The steel belts are quadratic, rectangular or triangular in a cross-section. The steel belts are arranged on inner surfaces by welding in a movable manner. The pipes are formed in a rectangular cross-section.

Description

Die Erfindung betrifft eine Vorrichtung zum Erwaermen eines Waermetransportfluides, bei der ein Waermelieferfluid einen Waermetauscher mit getrennten Kanaelen fuer das Waermelieferfluid und das Waermetransportfluid durchstroemt und bei der die inneren Waermeuebergangsflaechen in erfindungsgemaesser Weise profiliert sind. Waermetauscher mit profilierten, fluidseitigen Flaechen sind Stand der Technuik.The invention relates to a device for heating a heat transfer fluid, wherein a heat transfer fluid through a heat exchanger with separate channels for the heat transfer fluid and the heat transfer fluid and in which the inner Waermeuebergangsflaechen are profiled in accordance with the invention. Heat exchangers with profiled, fluid-side surfaces are state of the art.

Als naechstliegender Stand der Technik zeigt die DE 195 46 190.8 plane unprofilierte oder profilierte Waermeuebergangsflaechen. Die wirksamste Profilierung des Patentes DE 195 46 190.8 fuer die Fluidturbulenz und den Waermeuebergang ist die im Querschnitt kreislinienfoermige bzw krummlinige Profilierung 42 mit spitzer, einkantiger Profilrippe 47.As the closest prior art shows the DE 195 46 190.8 plan unprofiled or profiled heat transfer surfaces. The most effective profiling of the patent DE 195 46 190.8 for the fluid turbulence and the heat transfer is the kreislinienfoermige in cross section or curvilinear profiling 42 with pointed, single-edged tread rib 47 ,

Diese fuer den Waermeuebergang des Waermetauschers von Patent DE 195 46 190.8 optimale Profilierung 42 hat allerdings einen konstrruktions-technischen Nachteil: bei der Herstellung der Profilierung 42 entstehen an der Profilrippe 47 Spannungen und feine Risse im Material, die im Heizbetrieb des Waermetauschers durch Dehnung und Korrosion des Materials zum Leck fuehren.This for the heat transfer of the heat exchanger of patent DE 195 46 190.8 optimal profiling 42 However, has a design-technical disadvantage: in the production of the profiling 42 arise at the tread rib 47 Tensions and fine cracks in the material, which lead to leakage in the heat mode of the heat exchanger by stretching and corrosion of the material.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die turbulenzmaessig optimale Waermeuebergangseigenschaften hat, die das Waermelieferfluid auch unter Volllastbedingungen optimal herunterkuehlt, kompakt und preiswert ist und werkstoffmaessig das Material der Profilierung nicht unter schaedliche Spannungen gesetzt ist.The invention has for its object to provide a device which turbulence has optimal heat transfer properties, which cools the Waermelieferfluid optimal even under full load conditions, is compact and inexpensive and material moderately material of the profiling is not set under dangerous tensions.

Diese Aufgabe wird erfindungsgemaess dadurch geloest, dass die Kanaele des Waermetauschers durch ein Dppelrohr gebildet sind, dass das Innenrohr den Kanal fuer das Waermelieferfluid und der Mantelraum zwischen Innen- und Aussenrohr den Kanal fuer das Waermetransportfluid bilden, dass die Rohre plattenfoermig mit annaehernd rechteckigem Querschnitt ausgebildet sind, dass mindestens die grossflaechigen Aussenseiten des Innenrohres und die ihnen gegenueberliegenden grossflaechigen Innenseiten des Aussenrohres zueinander beabstandet sind und dass die Innenflaechen des Innenrohres und die Innenflaechen des Aussenrohres mit Stahlbaendern profiliert sind, die im Querschnitt quadratisch, rechteckig oder dreieckig sind und die sich auf den besagten Innenflaechen gegenueberliegen oder versetzt angeordnet sind, und wobei das Waermetransportfluid im Gegenstrom zum Waermelieferfluid stroemt. This object is achieved according to the invention in that the channels of the heat exchanger are formed by a Dppelrohr that the inner tube form the channel for the Waermelieferfluid and the mantle space between the inner and outer tube, the channel for the heat transfer fluid, that the tubes plate-shaped formed with an approximately rectangular cross-section are that at least the grossflaechigen outer sides of the inner tube and the opposite them großflaechigen inner sides of the outer tube are spaced from each other and that the Innenflaechen the inner tube and the inner surfaces of the outer tube are profiled with Stahlbaendern, which are square, rectangular or triangular in cross-section and on the said inner surfaces lie opposite or staggered, and wherein the heat transfer fluid flows in countercurrent to the heat transfer fluid.

Die genannten Stahlbaender, die fuer eine optimale Turbulenz der Fluide sorgen, werden auf die Innenflaechen des Warmetauschers aufgeschweisst. Die optimale Turbulenz der Fluide ist wichtig fuer den optimalen Waermeuebergang.The steel strips mentioned, which ensure optimum turbulence of the fluids, are welded onto the inner surfaces of the heat exchanger. The optimal turbulence of the fluids is important for the optimal heat transfer.
