ABSTRACT:
A sheet metal heating package for heat exchangers including a plurality of superimposed sheets having at least a partial profiling for instance embossments leaving free flow channels in between themselves, which sheets carry a coating serving as a surface protection, for instance a layer enamel, the sheet metal heating package having a profiling of the sheets, where at least the border edges of the respectively adjoining directly superposed sheets have a minimum spacing from each other at all points or are aligned so as not to contact each other, the border zones of the sheets and possibly the process technology-wise caused material accumulations arising at the border edges of the coating are in this way protected against chipping or spalling.
