Abstract

Die Erfindung betrifft einen Wärmeübertrager für brennstoffbeheizte Wassererhitzer, mit wasserführenden Rohren (16) und einem von den Rohren (16) durchsetzten Paket von Lamellen (18), die zwischen sich Spalte (20) zum Durchtritt der Verbrennungsgase bilden. Es wird vorgeschlagen, daß der Randbereich der Durchgangsöffnungen der Lamellen (18) mit von der Durchgangsöffnung ausgehenden, vorzugsweise gleichmäßig über den Umfang verteilten Radialschlitzen (22) versehen ist, die den Randbereich der Durchgangsöffnungen in mehrere Randsegmente (24) unterteilt, die klemmend auf den Rohren (16) aufsitzen. Dadurch ist eine sichere Verbindung zwischen den Lamellen (18) und den wasserführenden Rohren (16) des Wärmeübertragers (14) erreicht, wobei auf den ansonst notwendigen Lötvorgang verzichtet werden kann.
