Description

Die Erfindung bezieht sich auf einen Wärmetauscher, insbesondere für Gaswasserheizer, ,der aus einem von mehreren Rohren durchsetzten Lamellenkörper besteht und den oberen Abschluß einer von unten beheizten Heizkammer bildet.The invention relates to a heat exchanger, in particular for Gas water heater, which consists of a lamellar body interspersed with several pipes consists and forms the top of a heating chamber heated from below.

Es ist ein Lamellenblock bekannt, bei dem die Rohre gestaffelt und so angeordnet sind, daß, sie im Grundriß einander nicht überdecken. Bei dem bekannten Lamellenblock liegen jedoch in einer Ebene jeweils zwei oder mehrere Rohre. Für solche Lamellenblöcke werden verhältnismäßig hohe Lamellen benötigt. Außerdem ergeben sich bei den bekannten Lamellenblöcken verhältnismäßig, hohe Auftriebswiderstände.A lamellar block is known in which the tubes are staggered and are arranged so that they do not overlap in plan. With the well-known However, there are two or more tubes in a single plane. For such lamellar blocks are relatively high lamellae required. Also surrendered In the known lamellar blocks, there are relatively high lift resistances.

Es ist auch bekannt, die Rohre im Lamellenblock so anzuordnen, daß sie nach Art einer Zickzacklinie übereinanderliegen, wobei sich in jeder Schnittebene durch .die Heizkammer nur ein Rohr befindet. Dabei überdecken aber die Rohre im Grundriß einander. Diese Anordnung hat außerdem den Nachteil, daß sie einen hohen Heizschacht erfordert, um die notwendige Zahl der Rohre unterzubringen.It is also known to arrange the tubes in the lamellar block so that they lie on top of one another in the manner of a zigzag line, with each cutting plane there is only one pipe through the heating chamber. In doing so, however, the tubes cover the Ground plan each other. This arrangement also has the disadvantage that it has a high Heating shaft required to accommodate the necessary number of pipes.

Dien Erfindung liegt die Aufgabe zugrunde, unter Verwendung schmaler, wenig Material exfardernder Lamellen einen Lamellenblock mit möglichst geringem Auftriebswiderstand herzustellen.The invention is based on the object, using narrow, little material expelling lamellae a lamella block with as little as possible Establish buoyancy resistance.

Erfindungsgomäß wird das dadurch erreicht, daß die Rohre im Lamellenkörper derart gestaffelt angeordnet sind, daß sie im Grundrißeinander nicht überdecken und in jeder waagerechten Schnitt-,ebene durch die Heizkammer jeweils nur ein einziges Rohr liegt. Die Rohre liegen bei einer solchen Anordnung »schattenfrei« im Heizgasstrom, der nur geringen Auftriebswiderstand findet. Man kann die Lamellen des Lamellenkörpers bei einer solchen Anordnung aus schmalen Blechstreifen herstellen, die schräg, vorzugsweise im Winkel von 45°, zur Heizschachtwandung angeordnet werden.- Solche Lamellen lassen sich abfallfrei aus einem Blechstreifen ,ausstanzen.According to the invention this is achieved in that the tubes are in the lamellar body are staggered in such a way that they do not overlap in plan and in each horizontal section, plane through the heating chamber only one Pipe lies. With such an arrangement, the pipes are »shadow-free« in the hot gas flow, which only finds low lift resistance. You can use the slats of the slat body in such an arrangement made of narrow sheet metal strips, which are inclined, preferably at an angle of 45 ° to the heating shaft wall - leave such lamellas punch yourself out of a metal strip without waste.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung. Die Durchgangsöffnungen für die Rohre sind mit i bezeichnet. In kleinere mibeingestanzte Löcher 2 werden in bekannter Weise Hartlotstäh.e eingeführt.The figure shows an embodiment of the invention. The through openings for the tubes are denoted by i. In smaller holes 2 are mispunched Hartlotstäh.e introduced in a known manner.

Der freit: Durchgangsquerschnitt in der Heizkammer für die Heizgase .hat durch die Erfindung seinen überhaupt erreichbaren Höchstwert erhalten. Durchgeführte Versuche ergaben Meßwerte, die dem Beweis für höchste Belastungsmöglichkeit @erbrachten,The free: passage cross-section in the heating chamber for the heating gases .has obtained its maximum achievable value through the invention. Carried out Experiments yielded measured values that provided evidence of the highest possible load,
