Definitions
- the invention relates to an axial fan according to the preamble of claim 1 and an axial fan with an inlet nozzle according to the preamble of the independent claim 14, known from DE 33 04 297 C2 of the Applicant.
- Axial fan for conveying cooling air for cooling devices, in particular cooling modules in motor vehicles are known, for. B. as an axial fan with free-standing blade tips, which rotate in a stationary Zargenring a fan cowl.
- jacket fans in which a jacket is connected to the blade tips of the fan blades and rotates with the fan. Due to the circumferential jacket, blade tip losses, which arise from a flow around the blade tips as a result of the pressure differences on the pressure and suction sides of the fan blades, are avoided.
- the fan is driven by the internal combustion engine of the motor vehicle and is mounted opposite the block of the internal combustion engine.
- the cooling device consisting of heat exchangers, z.
- a cooling device with a motor-side driven and supported axial fan which rotates in a motor-fixed Zargenring.
- the main flow generated by the fan is superimposed on a bypass flow in the blade tip area.
- the axial depth of the known cooling device is relatively large, in particular because of the fan upstream annular bypass channel for generating the bypass flow.
- the leading edge of the jacket is set back in the direction of flow with respect to the leading edges of the fan blades (also referred to below as fan blades), ie. H. the shroud extends in the axial direction only over a part of the fan blade depth, via the downstream part.
- a fixed guide ring is arranged in this region of the reset of the shell, which preferably has a reduced diameter relative to the shroud.
- the fixed Zargenring is thus arranged in the flow direction in front of the shroud and radially within the shroud.
- the Zargenring may be formed substantially cylindrical or conical with an extension in the flow direction or be provided with a bell-shaped or funnel-shaped inlet region, which is preferably arranged opposite to the L compellingeranströmkanten offset from the flow direction.
- a deflecting element is arranged on the Zargenring in the region of the leading edge of the shroud, which generates a directed against the main flow through the axial fan gap flow.
- the annular deflecting element is extended by an annular surface extending in the direction of flow of the main flow which forms an annular gap with the outer lateral surface of the lateral ring.
- flow guide elements preferably in the form of a radial post-purge apparatus, can be provided on the annular surface, as described in the applicant's earlier application with the official file number xy. (Applicant's name: 06- 060) is described.
- the invention with the abovementioned embodiments thus provides only a partial sheathing of the fan blades with respect to the blade depth as a result of the resetting of the shell relative to the blade leading edges, wherein the stationary frame ring is arranged in the uncoated region, the area of the reset.
- the object of the invention is also achieved by an axial fan with the features of the independent claim 14.
- the axial fan according to the invention has a projecting shroud ring extending into an inlet nozzle, whereby the gap flow known from the prior art is achieved with a 180-degree deflection for flow stabilization.
- the axial fan according to the invention has a freestanding front and blade tip edge, ie, a gap in the form of a gusset is left between the upstream blade tip region and the inner surface of the jacket ring.
- the fan blades can thus be better flown in the front and outermost region, ie with lower losses, which result from a Fehlanströmung by the gap or nozzle flow.

- FIG. 2 shows a modification of the exemplary embodiment according to FIG. 1
- FIG. 3 shows a further exemplary embodiment of the invention with a jacket fan and inlet nozzle
- FIG. 4 shows a modification of the exemplary embodiment according to FIG. 1
- FIG. 5 shows a further modification of the exemplary embodiment according to FIG. 1
- FIG. 6 shows a further embodiment of the invention with an annular deflecting element arranged on the guide ring
- FIG. 7 shows a development of the exemplary embodiment according to FIG 6
- Fig. 8 shows a development of the embodiment of FIG. 7
- Fig. 9 is a representation of the fan flow for an axial fan after the
- FIG. 11 shows a representation of the main and gap flow in the case of an axial ventilator according to the invention.
- the axial fan 1 shows an axial fan 1 which is mounted via a clutch 2, preferably a fluid friction clutch, with respect to an internal combustion engine, not shown, of a motor vehicle and driven by the same.
- the axial fan 1 is part of a cooling device, which heat exchanger, not shown, for. B. may have a coolant radiator, a charge air cooler and a refrigerant condenser.
- the axial fan 1 is flown in the direction of an arrow L of air, is preferably arranged in the flow direction behind the heat exchangers, not shown, and sucks ambient air through the heat exchanger.
- the axial fan 1 is connected via a fan shroud, not shown, for guiding the cooling air with the upstream heat exchangers.
- the axial fan 1 has a hub 3 connected to the clutch 2 and axial blades 4 with a front edge 4 a and a trailing edge 4 b.
- the axis of rotation of the fan is designated by a.
- the axial blades 4 have a blade depth t which extends from the leading edge 4a to the trailing edge 4b.
- the blades 4 have blade tips (blade tips) 4c, to which a shroud 5 with a leading edge 5a and a trailing edge 5b is attached.
- the leading edge 5a is offset from the leading edges 4a of the fan blades 4 by an amount X1 in the flow direction L, while the trailing edge 5b is offset from the trailing edge 4b by an amount X2 against the flow direction.
- the axial extent I of the shroud 5 is thus smaller than the blade depth t.
- the area of the blade tips 4c, which lies in the flow direction in front of the leading edge 5a, ie the area X1 of the resetting of the leading edge 5a, has a reduced diameter D1.
- a corner region of the blade tips 4c is recessed, in which a stationary arranged guide ring 6 is arranged, wherein the guide ring 6 has a mean diameter D2, which is greater than the diameter D1, but smaller than the diameter of the leading edge 5a.
- the guide ring 6 is formed substantially cylindrical, overlaps in the axial direction with the axial blades 4 and is slightly opposite to the leading edges 4a, d. H,. opposite to the flow direction L.
- the guide ring 6 is preferably arranged fixed motor, ie, as well as the axial fan 1, ie between the rotating fan 1 and the fixed guide ring 6 occur no relative movements, so that a minimal gap can be realized.
- Fig. 2 shows a fan 7, which is a modification of the fan 1 according to Fig. 1, wherein the same reference numerals are used for the same parts as before.
- the fan 7 substantially corresponds to the fan 1, thus has a similar Axialbeschaufelung 4 and a similar shroud 5 on.
- a stationary guide ring 8 is arranged, which is conical or diffuser-like in design, ie widens in the flow direction L.
- the recessed blade tip region 4 c is adapted to the conical shape of the guide ring 8. Due to the diffuser-shaped guide ring 8, the substantially semiaxially oriented main flow of the fan 7 is taken into account, so that the flow is already given a radial component.
- FIG. 3 shows a further embodiment of the invention, in which an axial fan 9 has a jacket 10 with a protruding, cylindrical portion 10a, which projects into a cross-sectionally U-shaped or C-shaped inlet nozzle 11.
- a jacket fan with inlet nozzle is known from the aforementioned prior art and generates a gap or nozzle flow, which is superimposed in the blade tip region of the main flow and ensures stabilization of the main flow.
- the leading edges 4a of the fan blades 4 do not extend to the inner surface of the shell 10, whereby a gap s in the form of a gusset is formed.
- the fan blade 4 has a free blade tip edge 12 in the inflow-side region, which bounds the gusset s and can be flowed freely by the nozzle flow formed by the inlet nozzle 11. Due to the free blade tip edge 12 and the radially inwardly retracted blade leading edge 4a a Fehlanströmung is avoided by the affected with a peripheral component gap flow.
- the exemplary embodiments according to FIGS. 1 and 2, on the one hand, and the exemplary embodiment according to FIG. 3, on the other hand, are connected to one another by the common inventive idea that the leading edges of the fan blades are free in the blade tip region, i. H. are not sheathed. This avoids a false flow in both cases.
- FIGS. 1 and 2 show a further exemplary embodiment of the invention for a fan 13, which substantially corresponds to the fans 1 and 7 of the exemplary embodiments according to FIGS. 1 and 2. Different is the education of the
- the withdrawn blade tip region 4c is adapted to this shape of the guide ring 14 accordingly.
- Fig. 5 shows a further modification of the previous embodiment, ie for a fan 13, the shroud 5, a fixed guide ring 15 is connected upstream, which has at its air inlet region a radially inwardly extending aperture ring 15a.
- the aperture ring 15a covers the radial gap between the guide ring 15 and the blade tip portion 4c of the axial blades 4.
- FIG. 6 shows a further exemplary embodiment of the invention with an axial fan 16, which has axial blades 4 and a shroud 5.
- a guide ring 17, slightly conical and diffuser-like design, is connected upstream of the jacket ring 5 and has a leading edge 17a and an outflow edge 17b. Between the trailing edge 17b of the guide ring 17 and the leading edge 5a of the shroud 5, a radial gap 18 is left, to which an annular deflecting element 19 attached to the guide ring 17 is assigned.
- an inlet nozzle is formed, which allows a gap or nozzle flow, which will be explained in more detail in connection with the next embodiment.
- FIG. 7 shows a further embodiment of the invention, which represents a development of the embodiment of FIG. 6.
- An axial fan 20 has a Axialbeschaufelung 4 with a shroud 5 and an upstream guide ring 21, on which in addition to the annular deflecting element 19 in the axial and radial direction, parallel to the shroud 5 extending annular surface 22 connects.
- the main flow of the fan 20 is represented by three flow arrows P1, P2, P3, while a gap or nozzle flow is indicated by a fourth arrow P4.
- annular gap 23 Between the outer surface of the jacket ring 5 and the annular surface 22 is an annular gap 23 through which air flows from the pressure side of the fan against the main flow direction, is deflected in the deflecting element 19 and through the radial gap 18 in the fan 20, that is, the Axialbeschaufelung 4 occurs.
- This gap or nozzle flow indicated by the arrow P4, has a stabilizing effect on the main flow in the fan.
- the geometry of the guide ring 21 and the shroud 5 is such that a diffuser effect results, whereby the main flow P1, P2, P3 is deflected in a radial direction. This is at the cramped space in the motor vehicle in the axial direction, in particular by the downstream arranged, not shown engine block of great advantage. Fig.
- FIG. 8 shows a development of the embodiment of FIG. 7, wherein the annular surface 22 is further extended in the axial and radial directions and carries Strömungsleitmaschine 24, which cause a radial orientation of the fan outflow.
- the flow guide elements 24 may be formed in the manner of a radial Nachleitapparates, as described in the earlier application of the Applicant with the official file number xy ... (Sign of the Applicant: 06-B-060). With this embodiment, a relatively lossless, radially directed outflow from the fan can be achieved in a compact, axially limited construction.
- Fig. 9 shows a representation of the fan flow for an axial fan according to the prior art.
- the main flow is directed semi-axially, as indicated by parallel arrows P.
- In the upstream blade tip region forms a vortex W, which disturbs the main flow and deteriorates the efficiency of the fan.
- Fig. 10 shows a known from the prior art shell fan with so-called inlet nozzle, through which a nozzle flow, represented by the two outermost arrows D, is generated.
- FIG. 11 shows a further flow pattern for the axial ventilator 1 according to the invention according to the exemplary embodiment according to FIG. 1.
- the flow through the axial blading 4 extends in the direction of the arrows in the semiaxial direction.
- a nozzle flow is formed, which is indicated by the outermost arrow F.
