Abstract
A method for producing a heat exchanger having tubes that are each received at a longitudinal end side in an associated header, the tubes and the headers are formed out of aluminium. The method may include soldering the tubes and the headers to one another to form a coolant-conducting channel structure, and cold-forming the heat exchanger following the soldering of the tubes to the headers such that strength is thereby increased.
