Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung einer Brennkammer, insbesondere für gasbeheizte Wassererhitzer, deren Wände je aus zwei miteinander verschweißten Wandblechen (38, 40) bestehen, die mit örtlichen Ausformungen zur Bildung von Kanälen (46) für ein Fluid, insbesondere für als Kühlmittel dienendes Heizungswasser, versehen sind.The invention relates to a method for producing a Combustion chamber, especially for gas-fired water heaters, the walls of which are welded together from two Wall plates (38, 40) consist of local ones Formations for the formation of channels (46) for a fluid, especially for heating water used as a coolant, are provided.

Es wird vorgeschlagen, daß die Kanäle (46) nach dem Verschweißen entlang der späteren Kanalränder durch Ausformen der zwischen den Schweißnähten (48) sich befindenden Blechbereiche (42,44) mittels eines mit Druck zwischen die Wandbleche (38,40) eingeführten fluiden Arbeitsmittels gebildet werden. Dadurch wird die Fertigung vereinfacht und vermieden, daß sich in die Kanäle (46) mündende Spalte zwischen den Wandblechen (38,40) ergeben, die zur Korrosion führen können.

Figure 00000001
It is proposed that the channels (46) be formed after welding along the later channel edges by shaping the sheet metal areas (42, 44) between the weld seams (48) by means of a fluid working medium introduced with pressure between the wall sheets (38, 40) will. This simplifies production and avoids gaps opening into the channels (46) between the wall plates (38, 40) which can lead to corrosion.
