Arrangement of discrete structural parts, especially heat exchanger

摘要

In an arrangement of at least two discrete structural parts in package form which are spaced apart from each other, the individual structural parts are coated at least on one circumference of the structural part with a metal- or ceramic-powder collar. The powder collars serve as spacers between adjacent structural parts, are preferably sprayed on, and reliably prevent fretting corrosion between the structural parts.
