Definitions

  • the invention relates to a manufactured by forming, to be flowed through by a mass flow wire molding of at least one wire.
  • Wire shaped bodies of the type mentioned are known for a long time. They are used for a variety of purposes, such as cooling elements, filter cartridges, and the like.
  • a known wire molding is made of a wire having a round cross section.
  • the wire is usually entangled, knitted or woven to a precursor.
  • the precursor is converted in a forming device by plastic forming to form a wire shaped body, wherein the shaped wire body is formed according to the negative shape of the reforwarding device.
  • Wires with a round cross-section are used in particular because they are particularly suitable for the various processes that are commonly used for the preparation of the precursors.
  • round wires were also considered particularly advantageous because round wire cross-sections of mass flows, such as a liquid flow or a gas flow, which are to flow through the wire shaped body, can be flowed around particularly well due to the rounded surfaces.
  • this object is achieved by a shaped wire body with the features according to claim 1 and in particular by the fact that the wire over its length considered consistent, polygonal cross-sectional shape and that the wire is arranged in the wire shaped body such that the wire over its length undergoes a constant change in its spatial orientation.
  • a wire for the shaped wire body which has a constant polygonal cross-sectional shape over its length, instead of using a wire whose cross-section is round in shape.
  • a cross-section polygonal wire constantly changes its spatial orientation over the length considered in the wire shaped body, in the wire shaped body targeted laminar and turbulent flows can be generated, which influence the flow behavior targeted.
  • the turbulent flows in turn lead to a significant increase in the flow resistance of the shaped wire body according to the invention compared with shaped wire bodies, which consist of wires with round cross-sectional shapes. are made.

  • a cross-sectionally square wire with an edge length of 0.6 mm and a length of 1000 mm results in a weight saving of approximately 55% with approximately the same flow resistance.
  • the wire shaped body according to the invention it is possible to significantly save material while maintaining a constant flow behavior. It is also possible to influence and adjust the heat transfer behavior by selective selection of the cross-sectional shapes and wire lengths, the flow behavior and, as will also be explained, the heat transfer behavior.
  • the inventive wire shaped body proposed to use a wire having a rectangular or square cross-sectional shape, since these cross-sectional shapes are easily made by pulling the wire.
  • the wires Preferably, in this embodiment, the wires have identical cross-sectional shapes.

  • the reference used wire shaped body is made of a wire with a round cross-section.
  • the wire has a diameter d of 1.00 mm and a length 1 of 1000 mm. This results in a flow around cross-sectional area A p of 0.79 mm 2 at a resistance coefficient C w of 1, 2.
  • the wire molding is made of a square-section wire.
  • the wire cross-section has an edge length a of 0.79 mm, so that also results in a cross-sectional area A p of 0.79 mm 2 .

Abstract

L'invention concerne un corps façonné constitué d'au moins un fil métallique, réalisé par formage, destiné à permettre le passage d'un flux massique. Selon l'invention, le fil métallique présente une section transversale polygonale, constante sur sa longueur, et est disposé dans le corps façonné en fil métallique de manière à présenter un changement continuel de son orientation spatiale sur sa longueur.
