Abstract

Description

Wärmetauscher mit Kammersystem besitzen gegenüber „normalen Wärmetauschern” mit Rohrbögen zur Umleitung der Flüssigkeitsströme entscheidende Vorteile. Die Rohrbögen müssen einzelnen mit den Kühlrohren des Wärmetauscher verlötet werden was fertigungstechnisch einen höheren Aufwand darstellt und aufgrund der Unzahl von Schweißstellen die Wahrscheinlichkeit von Undichtigkeiten automatisch beinhaltet.Heat exchangers with a chamber system have decisive advantages over "normal heat exchangers" with elbows for diverting the liquid streams. The pipe bends must be individually soldered to the cooling tubes of the heat exchanger which manufacturing technology is a higher effort and due to the myriad of welds automatically includes the likelihood of leaks.

Die Kammerböden bestehen aus gestanzten und umgeformten Blechteilen in die kleine Leitungsbleche zur Wasserführung senkrecht eingeschweißt werden. Diese Kammerböden werden dann anschließend auf die Endrohre der Wärmetauscher gesetzt und mittels Laser verschweißt.The chamber bottoms are made of stamped and formed sheet metal parts in the small ducts to the water supply are welded vertically. These chamber bottoms are then then placed on the tailpipes of the heat exchanger and welded by laser.

Der Vorteil dieses Verfahrens gegenüber der bisher verwendeten Wärmetauscher mit Rohrbögen ergibt sich durch das Stanzen der Metallplatten und anschließende Verschweißen zu Kammerböden mit Leitungsblechen. Die Passgenauigkeit wird erheblich erhöht. Die Kammerböden sind formstabil und verformen sich folglich nicht beim Einschweißen der Endrohre. Aufgrund der hohen Passgenauigkeit und der reversiblen Fertigungsmöglichkeit kann zum Verschweißen ein automatischer Laser eingesetzt werden. Das ganze System besitzt aufgrund der Plattenkonstruktion und der eingeschweißten Mediumsleitungsblechen eine hohe Stabilität und hält hohen Drücken stand. Insgesamt sind die verwendeten Kammerböden schmäler als die bisherigen eingelöteten Rohrbögen. Desweiteren sind die glatten Schweißstellen (Stahl aus Stahl) stabiler und resistenter gegen aggressive Medien als gelötete Kupferverbindungen. Konstruktiv ermöglicht dieses Verfahren, dass mehr Lamellen bei gleicher Höhe des Wärmetauschers zum Einsatz kommen können, was wiederum die Leistungsfähigkeit des WT erhöht. Aufgrund der automatisierten Fertigungsweise mit reversiblen Prozessen entstehen Wärmetauscher die exakt immer die gleichen Abmaße besitzen.The advantage of this method over the previously used heat exchangers with elbows results from the punching of the metal plates and subsequent welding to chamber bottoms with duct plates. The accuracy of fit is significantly increased. The chamber bottoms are dimensionally stable and therefore do not deform during welding of the tailpipes. Due to the high accuracy of fit and the reversible manufacturing possibility for welding an automatic laser can be used. The whole system has a high stability due to the plate construction and the welded-in medium-conductor plates and withstands high pressures. Overall, the chamber bottoms used are narrower than the previous soldered pipe bends. Furthermore, the smooth welds (steel steel) are more stable and resistant to aggressive media than soldered copper compounds. In terms of design, this method allows more fins to be used at the same height of the heat exchanger, which in turn increases the efficiency of the WT. Due to the automated manufacturing process with reversible processes, heat exchangers are created that always have exactly the same dimensions.
