  • Such a flow straightener is an air guide element which is arranged with its air guide vanes immediately behind an axial fan in order to redirect the flow of air displaced by the axial fan impeller into as axial and uniform a flow as possible.
  • Such an air guide is often referred to as "Nachleitrad”.

It is important that the flow straightener has the lowest possible flow resistance, so that it only an insignificant pressure drop occurs in the amount of air flowing through it.

  • Fig. 1 illustrates an angle between the air flow and the fan axis in a peripheral optimum region of the radial length of the air guide vanes of the flow rectifier almost zero, but this angle grows radially outward and in particular radially inward relatively quickly. This leads to a divergent airflow.

This ensures a safe distance to a rotating impeller of the axial fan.
  • the number of air vanes can thereby decrease from the outer rings to the inner rings in order to realize in this way in each wreath an approximately equal distance between the respective blades of a series and thus to achieve the lowest possible flow resistance.

Abstract

L'invention concerne un redresseur d'écoulement (1) pour un ventilateur axial (2), comportant un corps de base (3) comprenant une couronne (4a, 4b, 4c, 4d, 4e) délimitée radialement à l'intérieur et à l'extérieur par des surfaces extérieures cylindriques (5, 6), pourvue d'une pluralité d'aubes directrices d'air (7) réparties dans la direction périphérique autour d'un axe longitudinal (X-X), disposées sensiblement radialement, s'étendant entre les surfaces extérieures (5, 6). Vues dans la direction périphérique, les aubes directrices d'air (7) s'étendent respectivement entre une arête d'aube d'attaque (7a) et une arête d'aube de fuite (7b) avec une courbure (R1) par rapport à la direction axiale (X-X). Pour minimiser, en cas d'écoulement volumique et d'amplitude de jet élevés, la divergence d'un écoulement d'air sortant d'un tel redresseur d'écoulement, le corps de base (3) comporte au moins deux couronnes (4a, 4, b, 4c, 4d, 4e) pourvues d'aubes directrices d'air.
