Definitions
- the present invention relates to an axial fan for conveying cooling air for a cooling device of a motor vehicle, having the features of the preamble of claim 1.
- Such an axial fan comprises a fan wheel with a plurality of vanes extending from a hub, as well as a shroud enclosing, encircling, and supported by the vanes. Furthermore, the axial fan comprises a Zargenring coaxial with the shroud ring is arranged so that an annular gap between the shroud ring and frame ring is formed. While the fan wheel rotates about a rotation axis in the operation of the axial fan, the Zargenring is fixed. In particular, with the help of a Zargenring having fan cover a flow channel can be defined, which leads a flow of cooling air from a heat exchanger of the cooling device to the fan. In the known axial fan also an inlet nozzle is formed in the region of the annular gap, which deflects a forming during operation of the axial fan in the region of the jacket ring return flow to an inlet side of the fan.
- such an axial fan In vehicle applications, such an axial fan is used to generate a cooling air flow when the vehicle is stationary and while driving to support a cooling air flow generated by the airstream.
- Such axial fans usually have to overcome a comparatively high pressure drop, so that they work heavily throttled. It is conceivable, for example, a throttle digit from 0.05 to 0.20, wherein the throttle digit from a dynamic pressure, based on a Lüfterradring Structure divided by the total pressure increase results.
- the total pressure increase is in turn composed of the dynamic pressure and the static pressure.
- the return flow is deflected to the inlet side of the fan wheel and thus fed again to a main flow conveyed by the fan wheel. It has been shown that with the aid of such an inlet nozzle the noise development can be significantly reduced. At the same time, the capacity of the fan can be maintained at high throttling.
- the inlet nozzle is arranged on the Zargenring so that it is stationary as the Zargenring, ie stationary.
- the inlet nozzle extends circumferentially closed circumferentially.
- the Zargenring can be arranged on a fan cover, for example, connects to a heat exchanger of the cooling device and defines a funded using the fan wheel cooling air flow to the fan leading inflow channel.
- a fan driving the drive is usually stationary on an internal combustion engine, which is arranged on vibration damping bearings movable on the vehicle body.
- the fan may be driven directly via a belt of the internal combustion engine. Operational of the vehicle vibrations of the engine can thus lead to relative movements between the fan and the Zargenring. Accordingly, the aforementioned annular gap is usually comparatively large in order to avoid collisions between the fan and the Zargenring. If, moreover, an inlet nozzle is provided on the frame ring, relative movements between the fan wheel and the inlet nozzle must also be taken into account here.
- Another axial fan is from the DE 10 2006 049 076 A1 known.
- Axial fans are known in which a plurality of flow guide elements are arranged within the stationary inlet nozzle in order to better channel the return flow.
- the present invention is concerned with the problem of providing for an axial fan of the type mentioned in an improved embodiment, which is characterized in particular by a simplified assembly, while achieving a high efficiency for the promotion of cooling air even with heavy throttling and the lowest possible noise shall be.
- the invention is based on the general idea of arranging an annular gap seal for sealing and / or throttling an annular gap located between frame ring and shroud ring on the shroud ring for the first time in an axial fan.
- annular gap seal With the aid of such an annular gap seal, leakage flows can be at least reduced which bypass the respective inlet nozzle through the annular gap. As a result, the function and efficiency of the axial fan can be increased.
- annular gap seals were arranged on the Zargenring, ie stationary, so that they extended starting from the Zargenring in the direction of the outer ring.
- the annular gap seal in which the annular gap seal is arranged on the jacket ring, it rotates with the jacket ring during operation of the axial fan.
- the annular gap seal can be specifically exploit centrifugal forces that occur during operation of the axial fan, so with a rotating fan.
- the annular gap seal can be shaped and arranged so that it reduces the annular gap with a rotating fan. It is particularly advantageous that all aerodynamic changes / optimizations on a single component, namely the fan, can be made. This means that the frame is fixed and all changes can be made to the fan wheel, without additional installations on the frame ring are required.
- the annular gap seal with respect to the shroud is a separate component which may be suitably attached thereto.
- the annular gap seal can be screwed, riveted, clamped, molded, welded, glued or vulcanized to the shroud.
- the annular gap seal expediently consists of a suitable sealing material, which in particular has a higher elasticity than materials from which the outer ring and the Zargenring are made.
- the annular gap seal can be molded or clamped in particular on the shroud.
- the arrangement of the annular gap seal on the shroud also includes an arrangement of the annular gap seal in a region of the shroud, which forms the inlet nozzle.
- the respective inlet nozzle on the jacket ring.
- the respective inlet nozzle forms part of the fan, whereby the respective inlet nozzle rotates in the operation of the axial fan together with the shroud, the blades and the hub.
- the invention thus proposes a rotating inlet nozzle.
- the arrangement of the inlet nozzle on the shroud ensures that the inlet nozzle always has the desired optimum relative position to the shroud, which considerably simplifies the assembly of the axial fan.
- the respective inlet nozzle can thereby be optimized in terms of their deflection function for the return flow, which improves the efficiency of the axial fan and reduces the noise emission of the axial fan with high pressure stability.
- the rotating inlet nozzle can be realized with a comparatively narrow gap, which increases the volume flow through the inlet nozzle and its impulse effect for the fan improved.
- the inlet nozzle can basically be arranged independently of the shroud, whether the annular gap seal is arranged on the shroud or on the frame, the presented here arrangement of the inlet nozzle on the shroud represents an independent aspect of the present invention, which is equivalent to the aspect of the annular gap seal arranged on the shroud is to be considered and in particular can be claimed independently of it.
- the respective inlet nozzle may be made integrally, that is, of the same material as the outer ring.
- the respective inlet nozzle is integrally formed on the shroud.
- it can also be provided to design the respective inlet nozzle with respect to the shroud ring as a separate component, which is then attached to the shroud ring in a suitable manner.
- the shroud ring can be made integral with the blades, so that the shroud ring is integrally formed on the blades. Further, optionally, the blades may also be formed integrally on the hub. Particularly advantageous is then a development in which the blades, the shroud and the respective inlet nozzle and in particular also the hub are formed in a single material-uniform component.
- the annular gap seal can accordingly have in profile a fixing region fixed to the jacket ring and a freestanding, elastic sealing region, wherein the sealing region is arranged so that it is elastically deformed by centrifugal forces during operation of the axial fan and moves in the direction of the frame ring.
- This construction has the consequence that the sealing effect of the annular gap seal is speed-dependent. If a high flow rate is required, the fan rotates a high speed, which results in that the sealing effect of the annular gap seal is improved. This is accompanied at the same time an increased efficiency of the capacity of the fan. At the same time it is avoided that the annular gap seal rests completely on the Zargenring and it may cause abrasion or heating due to friction.
- the shroud ring for the respective inlet nozzle may contain at least one inflow opening, which radially penetrates the shroud ring in the region of the inlet nozzle, so that the return flow can enter the inlet nozzle through the respective inflow opening.
- the respective inflow opening is arranged upstream of the inlet side of the fan wheel with respect to a main flow conveyed by the fan during operation of the axial flow fan.
