Definitions
- the invention relates to a radial fan according to the Preamble of claim 1.
- Radial fans are known (DE-PS 319 721) whose straight edge is straight. This leads to swiping past the wing on the tongue edge to a diminished Noise development compared to the case of one Outside edge of the sweeping wing parallel case tongue edge. However, the result is still not entirely satisfactory.
- the noise level can be adjusted by moving it away the housing tongue edge from the impeller edge, i.e. by a Enlargement of the housing radius in relation to the impeller radius reduce, which in turn the promotional capacity of the Blower is detrimental.
- a radial fan according to the preamble of the claim 1 is from Patent Abstracts of Japan, Volume 3, No. 148 (M-083), December 7, 1979 & JP-A-54 122 415 and DE-U-88 08 417 known.
- Case tongue edges with straight Edges are from DE-B-1 077 368 and CH-A-278 711 known.
- the object of the invention is to provide a radial fan, which further reduced the same output Has noise level.
- this object is achieved by a radial fan solved with the features of claim 1.
- FIG. 1 and 2 show a radial fan with a spiral Housing 1, which begins on a housing tongue 2 and in which a driven impeller 3 with blades 4 rotates.
- the edge 5 of the housing tongue 2 is opposite to the axially parallel here Outer edges 6 of the impeller blades 4 inclined and curved.
- the inclination or the course of the tongue edge is chosen so that the tongue edge at least a distance two successive impeller edges, preferably several such distances, covered.
- the housing tongue edge S-shaped the inclination of the tongue edge in Reference to the outer edges of the impeller in the area of the impeller center plane, this is the area of the largest volume flow is, is largest and on the edges, towards the Housing faces, decreases.
- FIG. 3 shows a double radial fan with a tongue edge structure, which essentially consists of a symmetrical Supplement to the form shown in FIG. 2 results.
