Abstract
In a method for the production of a heat exchanger, a turbulator insert is placed into a heat exchanging tube, with the turbulator insert having a solder applied thereon in at least one region. Weld spots using resistance welding are formed on an inner surface of the heat exchanging tube with the turbulator insert, and the inner surface of the heat exchanging tube is interlinked with the turbulator insert through brazing.
Claims13
A method for the production of a heat exchanger, comprising:
- placing a turbulator insert into a heat exchanging tube, with the turbulator insert having a solder applied thereon in at least one region;
- forming weld spots using resistance welding on an inner surface of the heat exchanging tube to form a connection with the turbulator insert, wherein the turbulator insert is fixed in position in the heat exchanging tube substantially air-gap free by the resistance welding;
- and
- interlinking the inner surface of the heat exchanging tube with the turbulator insert through brazing.
