Such lamella burners are from DE 197 24 817 A. and known from EP 0 913 632 A.

Bei den bekannten Lamellenbrennern deckt das Brennerdeck die Brennerwanne mit ihrem Gasgemisch-Raum ab. Dabei ist das Brennerdeck durch die in der Rohrschlange fließende Kühlflüssigkeit gekühlt. Um die Gasdichtheit nach außen zu gewährleisten, ist das Brennerdeck durch einen Rahmen abgeschlossen, der mittels eines Dichtungselementes zur Brennerwanne hin abgedichtet ist. Da die Rohrschlange direkt mit den Lamellen verbunden ist, werden diese ausreichend gekühlt und erfüllen ihre Funktion zufriedenstellend. Damit jedoch auch der Brennerrahmen so gekühlt wird, dass das Dichtungselement nicht überhitzt wird, muss zwischen den Lamellen und dem Brennerrahmen eine mechanische und gut wärmeleitende Verbindung vorhanden sein. Dies wird bei bekannten Lamellenbrennern dadurch erreicht, dass zumindest ein Teil der Lamellen mit dem Brennerrahmen verschweißt wird.In the known lamella burners, the burner deck covers the burner pan with their gas mixture room. The burner deck is through the in the Pipe coil flowing coolant cooled. To the gas tightness to the outside To ensure the burner deck is closed by a frame that is sealed to the burner pan by means of a sealing element. Since the Pipe coil directly connected to the fins, these will be sufficient cooled and perform their function satisfactorily. But with that also The burner frame is cooled so that the sealing element is not overheated, must be a mechanical and good between the fins and the burner frame there is a heat-conducting connection. This is the case with known lamella burners achieved in that at least part of the slats with the Torch frame is welded.

Diese Art der Verbindung zwischen Lamellen und Brennerrahmen des Brennerdecks ist nicht nur kostenintensiv, sondern kann durch den thermischen Prozess des Schweißens auch zum teilweisen Verziehen oder Verwerfen der Bauteile führen und zusätzliche Sichtprüfungen, Ausrichten der Bauteile und andere Nacharbeiten erforderlich machen.This type of connection between the fins and burner frame of the burner deck is not only cost-intensive, but can also be achieved through the thermal process welding also for partially warping or rejecting the components perform and additional visual inspections, alignment of components and others Make rework necessary.

Es ist Aufgabe der Erfindung, bei einem Lamellenbrenner der eingangs erwähnten Art die Verbindung zwischen den Lamellen und dem Brennerrahmen so zu vereinfachen, dass mit kostengünstiger ausführbarer Verbindungstechnik eine mechanisch feste und gut wärmeleitende Verbindung erreicht wird.It is an object of the invention in a lamella burner of the type mentioned at the beginning Kind of the connection between the slats and the burner frame like this to simplify that with inexpensive, executable connection technology mechanically firm and good heat-conducting connection is achieved.

Wie die Fig. 1 und 2 zeigen, kann ein Teil der Lamellen 10 in als Zapfen ausgebildete Verbindungsansätze 11 auslaufen. Der Brennerrahmen 20 ist an den Verbindungsstellen mit auf den Querschnitt der Verbindungsansätze 11 abgestimmten Verbindungsaufnahmen 21 versehen. Wie mit 11' gezeigt wird, werden die in die Verbindungsaufnahmen 21 des Brennerrahmens 20 eingeführten Verbindungsansätze 11 mit dem aus den Verbindungsaufnahmen 21 ragenden Teil auf den Schenkel des Brennerrahmens 20 abgebogen, wobei die Stirnseite der Lamelle 10 außerhalb des Verbindungsansatzes 11 gegen den Schenkel des Brennerrahmens 20 gezogen und an diesem verspannt wird. Auf diese Weise wird eine mechanisch feste und gut wärmeleitende Verbindung zwischen der Lamelle 10 und dem Brennerrahmen 20 erreicht, die einfach und kostengünstig herstellbar ist. Derselbe Effekt kann auch durch Verschränken des aus den Verbindungsaufnahmen 21 ragenden Teilen der Verbindungsansätze 11 erreicht werden. Auch ein Vernieten oder Verstemmen der herausragenden Teile der Verbindungsansätze 11 kann eine äquivalente Verbindungstechnik darstellen, wie die Fig. 3 und 4 zeigen. Dabei bilden sich eine Art Nietköpfe 11", die sich den Lamellen 10 abgekehrt am Schenkel des Brennerrahmens 20 abstützen. Die Verformung der Verbindungsansätze 11 wird dabei mit Hilfe eines Nietstempels 40 ausgeführt.As shown in FIGS. 1 and 2, part of the lamellae 10 can be formed as a pin Leakage approaches 11 expire. The burner frame 20 is on the Connection points with the cross section of the connection lugs 11 Connection recordings 21 provided. As shown at 11 ' those inserted into the connection receptacles 21 of the burner frame 20 Connection approaches 11 with the projecting from the connection receptacles 21 Part bent on the leg of the burner frame 20, the front side the lamella 10 outside the connecting projection 11 against the leg of the Burner frame 20 is pulled and clamped to it. In this way becomes a mechanically firm and good heat-conducting connection between the lamella 10 and the burner frame 20, which is simple and inexpensive can be produced. The same effect can also be achieved by interlacing the Connection receptacles 21 projecting parts of the connection lugs 11 reached become. Also riveting or caulking the outstanding parts of the connection lugs 11 may represent an equivalent connection technique, such as 3 and 4 show. This forms a kind of rivet heads 11 ", which are the Support the fins 10 turned away from the leg of the burner frame 20. The deformation the connection lugs 11 is made with the aid of a rivet punch 40 executed.

Wie Fig. 5 zeigt, kann die Verbindungsaufnahme 21 für den Verbindungsansatz 11 der Lamelle 10 auch auf zwei einander gegenüberliegenden Seiten ausgestanzte Haltelappen als verformbare Teilbereiche 22 aufweisen, die die Verbindungsaufnahme 21 im Ausgangszustand, d.h. beim Einführen des Verbindungsansatzes 11 der Lamelle 10 begrenzen, wie die Ansicht nach Fig. 6 verdeutlicht. Die Teilbereiche 22 sind dabei den Lamellen 10 abgekehrt nach außen gebogen und können mit einem Werkzeug 40 in die Ebene des Schenkels des Brennerrahmens 20 gedrückt werden, wie die Ansicht nach Fig. 7 zeigt. Dabei verspannen sich die Teilbereiche 22 an dem Verbindungsansatz 11 und stellen eine mechanisch feste und gut wärmeleitende Verbindung zwischen der Lamelle 10 und dem Brennerrahmen 20 her. Die Lamellen 10 bestehen vorzugsweise aus Aluminium, Cu-Legierungen oder ferritischem Edelstahl und der Brennerrahmen 20 aus ferritischem Edelstahl.5 shows, the connection receptacle 21 for the connection approach 11 of the lamella 10 are also punched out on two opposite sides Holding tabs as deformable portions 22 which the connection receptacle 21 in the initial state, i.e. when inserting the connection approach 11 of the lamella 10 limit, as the view of FIG. 6 illustrates. The subareas 22 face away from the slats 10 bent and can with a tool 40 in the plane of the leg of the Burner frame 20 are pressed, as the view of FIG. 7 shows. there the sub-areas 22 brace on the connecting projection 11 and pose a mechanically firm and good heat-conducting connection between the lamella 10 and the burner frame 20 ago. The slats 10 preferably consist of Aluminum, Cu alloys or ferritic stainless steel and the burner frame 20 made of ferritic stainless steel.

Die Rohrabschnitte 30 der Rohrschlange sind in Bohrungen 12 der Lamellen 10 eingesetzt und fest mit den Lamellen 10 verbunden.The pipe sections 30 of the coil are in bores 12 of the fins 10 used and firmly connected to the slats 10.

Wie die Seitenansicht nach Fig. 8 zeigt, können die Verbindungsansätze 11 an den Enden der Lamelle 10 auch Halteaufnahmen 13 und 14 aufweisen, die als zur Ober- und Unterseite des Brennerdecks hin offene Schlitze ausgebildet sind, in die als Haken ausgebildete Halteelemente 23 und 24 eines zweiteiligen Brennerrahmens 20.1 und 20.2 einführbar sind.As the side view of FIG. 8 shows, the connecting lugs 11 can the ends of the slat 10 also have holding receptacles 13 and 14, which as slots open towards the top and bottom of the burner deck are formed, into the holding elements 23 and 24 of a two-part burner frame designed as hooks 20.1 and 20.2 can be introduced.

Wie die Fig. 9 und 10 zeigen, ist die obere Halteaufnahme 13 im spitzen Winkel zum Schenkel des Brennerrahmens 20.1 geneigt, wobei die Neigung der Halteaufnahme 13 größer ist. Damit lässt sich erreichen, dass mit der Einführung des Halteelementes 23 in die Halteaufnahme 13 ein Zug auf die Lamelle 10 ausgeführt wird, so dass diese mit ihrem Verbindungsansatz 11 am Brennerrahmen 20.1 verspannt wird. Zudem kann auch zwischen dem Halteelement 23 und der Halteaufnahme 13 eine form- und/oder kraftschlüssige Verbindung hergestellt werden. 9 and 10 show, the upper holding receptacle 13 is at an acute angle inclined to the leg of the burner frame 20.1, the inclination of the holding receptacle 13 is larger. This means that with the introduction of the Holding element 23 in the holding receptacle 13 a train on the slat 10 executed is, so that this with its connecting lug 11 on the burner frame 20.1 is tensioned. In addition, between the holding element 23 and the Holding receptacle 13 made a positive and / or non-positive connection become.

Wie die Fig. 11 und 12 zeigen, wird das Halteelement 24 des Brennerrahmens 20.2 in die untere Halteaufnahme 14 des Verbindungsansatzes 11 eingeführt und mit zur Verbindung der Lamelle 11 am zusammengesetzten Brennerrahmen 20.1 und 20.2 ausgenützt. Beide Teile des Brennerrahmens 20.1 und 20.2 werden nach dem Einführen ihrer Halteelemente 23 und 24 in die Halteaufnahmen 13 und 14 der Lamellen 10 selbst miteinander verbunden und so in ihren Verbindungsstellungen an den Lamellen 10 form- und/oder kraftschlüssig gehalten.11 and 12 show, the holding member 24 of the burner frame 20.2 inserted into the lower holding receptacle 14 of the connection projection 11 and with to connect the lamella 11 to the assembled burner frame 20.1 and 20.2 exploited. Both parts of the burner frame 20.1 and 20.2 will after inserting their holding elements 23 and 24 into the holding receptacles 13 and 14 of the slats 10 themselves connected to each other and so in their connecting positions held on the slats 10 positively and / or non-positively.

Es bleibt noch zu erwähnen, dass nur ein Teil der Lamellen 10 mit dem Brennerrahmen 20 bzw. 20.1 und 20.2 verbunden werden müssen, um die mechanisch feste und gut wärmeleitende Verbindung zwischen den Lamellen und dem Brennerrahmen zu erhalten. Die restlichen Lamellen besitzen keine Verbindungsansätze 11 und sind über ihre Verbindungen mit den Rohrabschnitten 30 der Rohrschlange auf Abstand gehalten und fest verbundener Teil des Brennerdecks.It remains to be mentioned that only part of the fins 10 with the burner frame 20 or 20.1 and 20.2 must be connected to the mechanically firm and good heat-conducting connection between the slats and the Get burner frame. The remaining slats have no connecting lugs 11 and are connected to the pipe sections 30 via their connections the pipe coil is kept at a distance and a firmly connected part of the burner deck.
