Abstract
A method for producing a heat exchanger is disclosed. The method includes a) providing two heat exchanger plates of the heat exchanger that are to be joined to one another; b) wetting at least one common local joining zone of the two heat exchanger plates with solder; c) forming the heat exchanger by brazing the two heat exchanger plates via local heating of the at least one common joining zone.
Claims19
A method for producing a heat exchanger comprising:
- a) providing two heat exchanger plates of the heat exchanger that are to be joined to one another;
- b) wetting at least one common local joining zone of the two heat exchanger plates with solder;
- c) forming the heat exchanger by brazing the two heat exchanger plates via local heating of the at least one common local joining zone with at least one heating section of a brazing tool;
- and
- pressing the two heat exchanger plates together in a region of the at least one common local joining zone by at least one pressing element of the brazing tool that is configured for locally heating the at least one common local joining zone, wherein the at least one pressing element has a projection disposed in the at least one heating section that engages against one of the heat exchanger plates for pressing the two heat exchanger plates together.

- and
- curing the solder by cooling the at least one common local joining zone via a cooling-air device where cooling air is channeled through the brazing tool in a region of the at least one heating section.
