Zusammenfassung:Process for the manufacture of a heat exchanger, including a surface treatment, and heat exchanger thus obtained Process for the manufacture of a heat exchanger, in particular an evaporator, comprising the preparation (A), assembly (B) and brazing (C) of components of the heat exchanger (1), the brazing (C) being carried out under given temperature conditions. Prior to the assembling (C) and to the brazing (B), a surface treatment operation (A101, A114) is carried out, consisting in applying a coating (102) to a chosen component (6), said coating comprising a support, at least one active agent suitable for giving the heat exchanger (1) chosen properties during its operation, and at least one thermal protection agent suitable for enabling the coating (102) to withstand the brazing temperature conditions.
