Heat exchange and process for producing the heat exchanger

摘要

The invention relates to a heat exchanger comprising two manifolds (10). Profiled pipe sections (11) are accommodated with a lamella configuration (12) between said manifolds. According to the invention, an obstructing means (13) for preventing the flow of solder is provided on the exterior of the profiled pipe section (11) between the manifold (10) and the lamella configuration (12). The invention also relates to a method for producing a heat exchanger. The invention provides that the obstructing means (13) is formed on the profiled pipe sections (11) before the sections are cut from a profiled pipe billet.
