Abstract
The invention relates to a method for producing a corrugated fin element for a heating register or for another heating device, through which corrugated fin element a flow can pass, to a corrugated fin element produced according to such a method, and to a heating register designed with such corrugated fin elements, wherein the corrugated fin elements are produced by unfolding.
Claims4
A method for producing a corrugated fin element, wherein the corrugated fin element comprises a plurality of corrugated fins of wave-shaped design, the method comprising:
- producing a base element having apexes of the plurality of corrugated fins that are in contact with adjacent apexes or are arranged at a distance to the adjacent apexes substantially smaller than a breadth of one of the apexes,
- impacting the base element with a tensile force so as to pull the base element apart such that a distance between the adjacent apexes is increased by deformation and a total length of the corrugated fin element increases relative to the base element, wherein in the base element, swages are formed in lamella legs joining the apexes;
- and
- after impacting the base element with the tensile force, impacting the apexes with a pressing force transversely to a longitudinal extension of one of (1) the base element or (2) the corrugated fin element.
