Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Wärmeübertragers für brennstoffbeheizte Wassererhitzer, mit wasserführenden Rohren und von diesen durchsetzten Lamellen, die zwischen sich Spalte zum Durchtritt der Verbrennungsgase bilden und durch Aufweiten der Rohre spaltlos an deren Umfang anliegen. Es wird vorgeschlagen, daß der die Rohre (10) aufweitende Arbeitsdruck bzw. der Preßdruck zwischen Rohr (10) und Lamelle (12) so groß gewählt und die Lamellen (12) so gestaltet bzw. bemessen sind, daß auch bei Verbrennungsgastemperaturen im Bereich von 1300°C die Lamellenfußbereiche (16) unter die Rekristallisationstemperatur des Lamellenwerkstoffs gekühlt sind und ein Festsitz der Lamellen (12) auf den Rohren (16) ohne Lötung gewährleistet ist. Dadurch kann auch bei den hohen Verbrennungsgastemperaturen ausgesetzten Primärwärmeübertragern eine Lötverbindung zwischen den Rohren und den Lamellen entfallen.
