METHOD AND FACILITY FOR PRODUCING A HEAT-EXCHANGER ELEMENT INTENDED TO BE BRAZED

摘要

The element (12) is produced by profiling. The method comprises a step of greasing the element (12) before profiling and a step of degreasing said element (12) after profiling intended, in particular, to cause the greasing oil remaining on the element (12) after profiling to evaporate or be destroyed. The degreasing step is carried out by projecting at least one plasma jet (J) onto the surface of the element (12) after profiling. The plasma jet (J) is produced by a plasma torch (30) at atmospheric pressure.
