Definitions
- the invention relates to a spiral housing of a centrifugal fan and a centrifugal fan with such a spiral housing.
- the centrifugal fans have the task to collect the air flow at the outlet of the centrifugal fan to flow in one direction let and act as Nachleitgeometrie.
- a spiral housing has in the boundary region of the spiral main body and the outlet a constriction, which is referred to in professional circles as a housing tongue.
- this housing tongue must be arranged close to the fan wheel in order to achieve a good efficiency of the centrifugal fan.
- the housing tongue leads to strong tonal components in the noise spectrum of the fan (rotary sound), which are perceived as disturbing and significantly increase the noise level.
- the invention is therefore based on the object to provide a spiral housing that has a good efficiency with reduced noise generation with low rotational sounds.
- the spiral housing is preferably formed in several parts, in particular in two parts with a side part and a lower part, which are substantially centrally separated in axial section.
- the side part has an axial Suction opening with a surrounding opening edge portion, which is viewed in the radial direction immediately followed by a circumferentially extending transition section which is spaced in a from the housing tongue in the circumferential direction over a predetermined angle réellere- ckenden initial section in the axial direction to the opening edge portion and a Has flow cross-section in the circumferential direction enlarging course until axial surfaces of the opening edge portion and transition portion extend in the same plane.
- the shape according to the invention is achieved in that on the one hand in the area of the housing tongue a small axial distance between the impeller and spiral housing, on the other hand, an increased axial distance in the remaining region of the spiral can be realized. This increases efficiency and reduces the rotational noise of a centrifugal fan starting the volute.
- the transition section has the course which increases the flow cross-section in the circumferential direction until the axial surfaces of the opening edge section and transition section extend in the same plane perpendicular to a rotation axis of the spiral housing. This means that the axial surface of the opening edge portion and the transition portion are aligned in the transition portion to the central axis in each section perpendicular to the central axis.
- the axial surface of the opening edge portion is perpendicular to the rotation axis of the volute casing over the entire circumference.
- the transition section thus changes its contour with respect to the opening edge section and increases the flow cross-sectional area along its extent in the circumferential direction.
- the opening edge portion runs over the entire circumference on an axial plane. This allows a comparatively large axial height of the spiral housing in the intake and the region of the impeller.
- the spiral housing in the radial direction of the transition section an at least partially the pressure chamber of the volute forming pressure chamber section adjoins, the flow cross-sectional area is determined in the initial section by a contour which merges tangentially in the radial section in the transition section.
- the pressure space section is the radially outer side region within the spiral housing, in which the flow is conveyed essentially exclusively in the circumferential direction.
- the volume of the pressure chamber section inside the spiral housing is significantly larger than the volume of the transition section. In the initial section of the transition section and the pressure chamber section go through the contour according to the invention in radial section continuously in one another.
- the initial section extends from the housing tongue, that is, the narrowest point in the volute in the circumferential direction over an angle of 5 - 270 °, more preferably over an angle of 20 - 180 °.
- the course of the transition section described above with respect to the opening edge section or the pressure space section is preferably carried out continuously over the entire angular range.
- a middle section adjoins the initial section, in which the axial surfaces of the opening edge section and transition section run in the same plane perpendicular to the axis of rotation and the flow cross section formed by the transition section is constant. In other words, the transition section and the opening edge section coincide in the middle section and form a flat surface.
- the outlet section can adjoin the central section directly in the circumferential direction.
- an embodiment of the spiral housing is advantageous in which adjoins in the circumferential direction of the central portion of an end portion in which the transition portion forms an axially inwardly directed, the flow cross-section reducing axial stage. The enlarged in the initial section flow cross-sectional area is thereby reduced again in the end section.
- the outlet is adjoined directly at the end section.
- the axial step is formed in the circumferential direction offset from the housing tongue, so that the flow can be influenced independently of the housing tongue.
- the axial stage has an extent in the circumferential direction with an alignment with the housing tongue. The axial stage thus absorbs the spiral shape, without pointing directly into the outlet.
- the outlet closes in an outlet portion to the spiral shape in the tangential direction, i. with straight shape, on. It is advantageous to form the axial step in the circumferential direction in the transition region from the spiral shape into the straight shape of the outlet.
- the suction opening is rotationally symmetrical and designed as an inlet nozzle.
- the invention also includes a centrifugal fan with an above-described spiral housing.
- Fig. 1 is a perspective view of an embodiment of a spiral housing
- FIGS. 1 and 2 show a plan view with sectional views A-A and B-B of the spiral housing from FIG. 1.
- FIGS. 1 and 2 show an embodiment of a spiral housing 1 according to the invention of a centrifugal fan in various views.
- the spiral housing 1 is formed in two parts with a side part 2 and a lower part 20. On an axial central axis, the motor-driven fan, not shown, is arranged.
- the bottleneck referred to as housing tongue 10 forms in the circumferential direction (seen in the flow direction) a starting point for an adapted contour of different sections of the spiral housing 1 to increase the efficiency and reduce the noise during operation.
- the spiral shape of the spiral housing 1 is followed by a tangentially extending outlet 11.
- the cross section of the outlet 1 1 can have any shape and, for example, be round, oval or elliptical.
- the side part 2 has an axial suction opening 3 with a peripheral opening edge portion 4, which forms an axial surface.
- the opening edge portion 4 extends over its entire circumference perpendicular to the axis of rotation of the spiral housing 1.
- the suction opening 3 is formed as an inlet nozzle with an axially inwardly extending into the intake 3 in the direction of impeller nozzle portion.
- the opening edge section 4 is adjoined in the radial direction directly by the circumferentially extending transition section 5, which is spaced in an axial direction from the housing tongue 10 in the circumferential direction over the angle ⁇ of over 90 ° extending starting portion 7 to the opening edge portion 4 and a Has in the axial direction widening course through which the flow cross-section in the transition section 5 is increased in the circumferential direction.
- This widening course of the transition section 5 extends in the circumferential direction until the axial surfaces of the opening edge section 4 and of the transition section 5 extend in the same axial plane perpendicular to the axis of rotation of the spiral housing 1.
- the initial section 7 Adjoining the transition section 5 in the radial direction of the pressure chamber of the volute casing 1 forming pressure chamber section 6, the flow cross-sectional area in the adjoining the housing tongue 10 the initial section 7 has a contour that merges tangentially in the radial section in the transition section 5, as well can be seen in the radial section BB.
- the initial section 7 ends in the circumferential direction as soon as the transition section 5 and the opening edge section 4 have a tangential tangential in radial section, i. in this case extend in the same axial plane perpendicular to the axis of rotation of the spiral housing 1. This area forms the middle section 8 with a constant flow cross section of the transition section 5.
- the axial stage 12 is formed as a kind of second housing tongue in the circumferential direction offset from the actual housing tongue 10. The in the circumferential direction initially increasing and then constant flow cross section in the transition section 5 is reduced by the axial stage 12 again.
- the axial stages fe 12 is formed in the transition region of the spiral shape in the straight shape of the outlet 1 1, but extends in the circumferential direction on the
- Case tongue 10 too.
- the housing tongue 10 and the axial stage 12 fluidly cooperate, although they are circumferentially spaced.
- a consideration of the spiral housing 1 in the radial direction shows that the flow cross-sectional area of the pressure chamber section 6 forming the pressure chamber increases abruptly in the middle section 8 in relation to the transition section 5. These enlarged dimensions remain until the end section 9 up to the outlet 11. In addition, the flow cross-sectional area in the pressure chamber section 6 also increases steadily in the circumferential direction.
- the lower part 20 has, in addition to the axially depressed receptacle for the impeller, a flat extension in the radial direction without the special design of the side part 2.
- the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use.
- the outer contour of the spiral housing which does not influence the flow, can be shaped as desired.
