Definitions
- the invention relates to a fan with axial blades, in particular for radiators of motor vehicles according to claims 1 or 2 of the Main application 199 29 978.1 of the applicant.
- the Air-guiding elements are in the hub and Air-guiding elements on the suction side of the axial blades arranged.
- the air guiding elements extend over the entire blade division, that is, from the leading edge of an axial blade to the leading edge of one adjacent axial blade.
- This particular embodiment of the Air guiding elements, as shown in FIGS. 3 and 4 of the main application is thus a continuous surface or between two blades the wall for a closed flow channel. With certain These closed flow channels can provide flow conditions disadvantageous, in particular they can lead to congestion effects and vortex formation, that means lead to flow losses.
- the task of this additional application corresponds to that of the aforementioned Main application, it aims at a further advantageous embodiment of the Invention after the main application, in particular an avoidance of aforementioned congestion effects due to a closed flow channel.
- the air guiding elements are considered fin-like Stabilizers formed, which are only in the circumferential direction Range from 1% to 40% of the blade pitch.
- the air control elements leave one between two blades and the hub open flow channel, in which the hub flow and Blade flow are controlled.
- the stabilizers in Blade root area cause on the suction side, the blades a Separation of hub and blade flow and prevent separation the flow as well as a harmful vortex formation.
- Similar fin-like air guiding elements are known per se, namely as so-called boundary layer fences from DE 26 14 318 C2 or as so-called auxiliary wing from DE 27 56 880 C2.
- these are Border layer fences or auxiliary wings according to the prior art in the radial outermost area of the blades, that is in the blade tip area arranged.
- These boundary layer fences are supposed to flow on the one hand Supply energy and on the other hand a flow around the blade tips Prevent (from the pressure side to the suction side).
- They are opposite Stabilizers according to the invention in the vicinity of the hub, that is in the Blade root area arranged.
- the Length of the stabilizers as seen in the direction of air flow, the length of the Axial blades, with the front edge of the stabilizers slightly opposite the blade leading edge can be offset in the flow direction.
- the area of the stabilizers is preferably light in the radial direction curved outwards, that is, slightly concave. This too Measure takes the course of the flow in the blade root area Bill.
- the stabilizers in one radial range from 0 to 40% of the blade height H, preferably from 0 up to 20% are arranged. In this area the hub flow and the flow at the blade root can be most effectively influenced.
- the hub in a fluid friction clutch on its inner area, which on its Front has radially aligned cooling fins.
- the latter generate one essentially radially oriented air flow, a so-called cooling air flow.
- each stabilizer Assigned radial blade elements that is, so-called flow dividers after the main registration.
- the latter reach into the front edge radially oriented cooling air flow and steer this relatively low loss on the pressure side of the blades, i.e. in the area of the hub ramp around.
- the outer surfaces of the radial blade element and the hub ramp a common one Area so that a favorable flow in the hub area is achieved becomes.
- the areas of the Stabilizer, the radial blade element and the hub ramp into each other over, so that the blade root pressure and suction side of one common area is surrounded, which is a particularly low loss Flow generated.
- FIG. 1 shows an axial fan 1 with eight substantially radially oriented fan blades 2, which are fastened on a hub 3.
- This fan 1 or its hub 3 is fastened on a fluid friction clutch 4 with radially extending cooling fins 4 ′, which drives the fan 1 in the direction of arrow A.
- Stabilizers 5 and radial blade elements 6 are arranged in the area of the hub 3.
- Fig. 2 shows a side view of the fan 1 with a view of the blade 2 in the direction of its radial longitudinal axis.
- This blade 2 has a leading edge or leading edge 7, a trailing or trailing edge 8 and a suction side 9 and a pressure side 10.
- Arranged on the suction side 9 is the fin-like stabilizer 5, which has an outer boundary line 11 and an inner boundary line 12 (at the connection point with the blade 2).
- the circumferential extension s of the stabilizer 5 increases from the inflow side (s 1 ) to the outflow side (s 2 ), ie s 2 > s 1.
- the length I of the stabilizer 5 essentially corresponds to the blade length L, the front edge 13 of the stabilizer 5 is set back somewhat from the front edge 7 of the blade, while the rear edge 14 is approximately flush with the rear edge 8 of the blade.
- the length L can be approximately 175 mm.
- the radial blade element 6 In the front area of the hub 3 is in the direction of flow (that is against the direction of rotation A) in front of the blade leading edge 7, the radial blade element 6 arranged, which in the main application also as Flow divider was called. This radial blade element covers the front part of the fluid friction clutch 4 in the axial direction, while the front edge 15 of the hub 3 is somewhat in this area is reset.
- the fan blades 2 have a radial extension or height H.
- the stabilizers 5 are arranged, which are slightly concave, that is curved outward in the radial direction.
- the stabilizers 5 can be demolded in the axial direction (in the direction of the axis of rotation M). This is particularly advantageous if the fan is injection molded as a plastic part or manufactured as a cast part.
- the dashed lines 16 show the course of the hub ramp on the back (pressure side) of the blade 2.
- the fan 4 shows the fan 1 in a view from the rear, that is to say in the direction of the axis of rotation M.
- the fan blade 2 which is injection molded as a plastic part, has in its left, that is to say the suction side region, the stabilizer 5 which projects approximately at right angles and which is connected to the fan blade 2 is molded.
- the axial demoldability of the stabilizers 5 is also evident here.
- the upper edge of the hub ramp is marked with the reference number 16 on the right side of the blade.
- FIG. 6 shows a section along the line VI-VI in FIG. 4 looking towards the suction side 9 of the blade 2.
- the axial demoldability is clear for the cut area 5 ′ of the stabilizer 5.
- FIG. 7 shows an enlarged view, that is to say a partial view of FIG. 1 for the blade root region.
- the surfaces of the stabilizers 5, the radial blade elements or flow dividers 6 and the hub ramp 16 can clearly be seen here.
- the surface elements 5 and 6 are interrupted in this embodiment by the front edge 7 of the blade 2.
- FIG 8 shows a further exemplary embodiment in which the outer surfaces 5a and 6a of the stabilizers 5 and the radial blade elements 6 are integrated into one another in such a way that they form a common, seamless surface with a common front edge 17.
- the surface element 6a therefore merges with the surface element 5a on the suction side of the blade 2 and with the surface element 16 of the hub ramp on the pressure side of the blade. This results in a low-loss flow around the blade root, that is to say in the hub region, the essentially radially oriented cooling air flow of the fluid friction clutch being brought together in a controlled manner with the flow around the blade. This can improve the performance of this fan, especially in connection with the clutch.
