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.

The invention relates to a heat exchanger for fuel-heated water heaters, with water-carrying pipes (16) and a packet of fins (18) which are penetrated by the pipes (16) and form gaps (20) between them for the passage of the combustion gases. It is proposed that the edge region of the through openings of the lamellae (18) be provided with radial slots (22) starting from the through opening and preferably evenly distributed over the circumference, which divides the edge region of the through openings into a plurality of edge segments (24) which clamp onto the Mount the tubes (16). As a result, a secure connection between the fins (18) and the water-carrying pipes (16) of the heat exchanger (14) is achieved, and the otherwise necessary soldering process can be dispensed with.
