Abstract

Die Erfindung betrifft einen Gasbrenner mit einem Basisteil (10), das eine Gaszuführung (11) aufweist und auf dem ein Lamellenblock (30) abgedichtet befestigbar ist, wobei der Lamellenblock aus parallel zueinanderstehenden Lamellen (31) gebildet ist, aus denen Wärme mittels Kühlelementen (32) auskoppelbar ist, und wobei der Lamellenblock von einem Rahmen (20) umgeben ist, der die in Strömungsrichtung des Brenngases verlaufenden Seiten des Lamellenblocks zumindest teilweise überdeckt. Zur Verminderung von Wärmeeinflüssen auf den Dichtungsbereich zwischen Basisteil und Rahmen ist es erfindungsgemäß vorgesehen, daß zumindest ein Teil der Lamellen mittels Wärmebrücken (24) an den Rahmen angeschlossen sind.

The invention relates to a gas burner with a base part (10) which has a gas supply (11) and on which a lamella block (30) can be fastened in a sealed manner, the lamella block being formed from mutually parallel lamellae (31) from which heat is generated by means of cooling elements ( 32) can be decoupled, and the lamella block being surrounded by a frame (20) which at least partially covers the sides of the lamella block running in the flow direction of the fuel gas. In order to reduce the influence of heat on the sealing area between the base part and the frame, the invention provides that at least some of the slats are connected to the frame by means of thermal bridges (24).
