Schlangenförmiger Wärmetauscher und Verfahren zu seiner Herstellung

摘要

A method for building a serpentine heat exchanger, particularly a condenser for refrigerating circuits being profiled in such a way to present from a lateral side view and relative to at least one part of its length an inclination the direction of which is suddenly or progressively inverted at least once relative to a plane which is substantially parallel to one of the directions defined by the extension of the exchanger (3), in particular relative to a plane substantially parallel to the principal direction of a flow of air in which the exchanger (3) is located, and in special manner relative to a substantially vertical or substantially horizontal plane. According to the invention, the method comprises the following steps: a) the construction at least of the serpentine or of the complete exchanger in a flat configuration; b) the bending and/or moulding, or deforming of the flat serpentine or of the flat complete exchanger in a way to assume the desired inclinations.
