Definitions
- the invention relates to a radial fan, in particular for heating and Air conditioning systems of motor vehicles in the preamble of claim 1 specified type.
- the space available in a motor vehicle for the installation of a heating and Ventilation device is generally very small, and if the air with one Centrifugal blowers should be set in motion, especially around a Achieving noiseless work is taking up little space Design achieved when the air from that driving the blower Electric motor opposite side enters directly into the housing. The Cooling the engine is therefore a difficult problem.
- a radial fan especially for heating and Air conditioning systems of motor vehicles known, in which one by one Electric motor driven fan wheel and a surrounding, spiral housing are provided.
- the housing has an in a suction intake opening and one from the interior of the Housing leading outward air outlet opening, which is the Air intake opening opposite closed housing part of the housing has a bowl-like depression in which at least a part of the Electric motor is housed.
- the other part of the electric motor is located itself within a cupped arch, which is the hub of the Connects impeller with its fan ring.
- the support disc has on the radial outer area axially pointing away from the electric motor Fan blades and on the smooth, closed inner surface second fan blades through which a cooling air flow for cooling the Electric motor is branched from the main air flow in the spiral space.
- a radial fan also improves cooling of the electric motor achieved a housing, the front of which is provided with an air inlet opening and the back of which houses a drive motor for a fan wheel that has a fan ring with fan blades and a Nahe, which by means of a cup-shaped arched support disc are connected to each other.
- a good Cooling of the electric motor is achieved in that the support disk with Breakthroughs is provided, whereby cooling air to the suction side of the Fan wheel is sucked. (DE 29 39 385).
- DE 34 27 565 also drives a motor driven by an electric motor Radial blower with a radial fan already known, in which one Washer with axially pointing away from the engine on the radial outer area Fan blades is provided.
- the support disk has openings, through which the cooling air heated by the electric motor to the suction side of the Blower wheel arrives and mixed with the conveying air and into the spiral room is derived. Because the openings in the support plate short-circuit currents allow between the pressure and suction side and therefore to noise this fan wheel is less suitable for low-noise operation.
- the invention has for its object a radial fan of the beginning mentioned type in such a way that a further lowering of Temperatures of the engine components in an uncritical range by better ventilation of the drive motor and thus an increase in Lifetime of the drive motors can be achieved.
- This task is accomplished by the Features characterized in claim 1 solved.
- the radial fan according to the invention is characterized by a low-noise Run and effective cooling of the drive motor and its components and is due to its compact structure also in motor vehicles with narrow Space can be used advantageously.
- the fan wheel with the hub and the fan ring with the are advantageous Fan blades as well as with the support disk containing the openings a single component, in particular a plastic injection molded part.
- Figure 1 shows a radial fan, especially for heating and Air conditioning systems of motor vehicles with a spiral (fan housing 1, the front 3 is provided with an air inlet opening 5 and the Back 7 has a housing extension 9 closed to the outside, in which an electric motor 11 serving as a drive motor is arranged.
- the electric motor is at least one on all sides Air gap surrounded.
- a small part of the conveyed air is used as cooling air for the drive motor 11 branches and flows in the direction of arrows 25 through the Air duct 27 and through the motor openings 29 and 31 in the Drive motor 11. There are none for electric motors with open end shields separate engine openings required.
- the cooling air takes waste heat of the drive motor 11 and leaves the motor interior through openings 33, which in the end face 35 of the shaft-side bearing plate 37 of the Drive motor 11 are arranged.
- the cooling air flows through the recesses in the End shields.
- the cooling air enters a space 39 between the End shield 37 and the support shell 17, which to the suction side 41 of the Blower wheel 19 opened because of the openings 43 in the carrier shell 17 is so that the heated cooling air mixes with the conveying air of the fan and is discharged into the spiral space 23.
- the space 39 is on the pressure side of the fan, namely on Spiral chamber 23 largely sealed off in that a cylindrical approach 45 on the support shell 17 with a narrow gap 47 over a certain axial length of Shell surface 49 protrudes and additionally with the end face 51 with a small Distance from an end face 53 of the motor housing 55 is opposite.
- An increase in cooling air flow through the drive motor 11 is achieved according to the invention in that the openings 43 are formed in this way are that with rotation of the impeller 19, a vacuum on the Drive motor 11 facing away from side 57 support shell 17 is generated.
- FIG. 2 shows an impeller 19 with the hub 15, the fan ring 20 with the fan blades 21 and the hub 15 and the fan ring 20 connecting Carrier shell 17.
- this carrier shell 17 there are openings 43 arranged at least in front of the in the direction 59 of the impeller 19th front ends covered hood-shaped elevations 61, such that these are designed to be closed in the running direction of the impeller 19 and on the opposite side in the running direction of the impeller 19 Outlet openings 65 for discharging at least a portion of the through the Drive motor 11 pass cooling air.
- the fan wheel 19 is advantageously made 2 from a one-piece plastic injection molded part.
- inner wings 69 are provided, which are extend from the hub 15 to the ends of the openings 43. These wings 69 cause an additional delivery pressure only for the Engine cooling air and regardless of the throttling of the fan air.
- FIGS 3 and 4 show a second embodiment of a Radial fan with a housing 71 composed of two halves, the is preferably made of plastic.
- This housing 71 points to the Front an air intake opening 73 and one in its circumferential range for this purpose, air outlet 74 located at a 90 ° offset level.
- Spiral housing formed housing 71 surrounds an impeller 75, the preferably consists of a plastic injection molded part and a hub 77 and one
- the fan ring 79 has an essentially bowl-shaped design Carrier 81 are connected to each other.
- the hub 77 is non-rotatable with a Shaft 83 of an electric drive motor 85 connected by the Back 87 of the housing 71 is held.
- the rear wall 87 has a cylindrical extension 91, which has webs 93 a pole ring 95 of the drive motor 85 receives such that between the Polring 95 and the cylindrical extension 91 an air passage opening 99th a defined cross section is available, which is open to the outside. Between the pole ring 95 and the inner part of the motor, in particular the Windings, there are further openings 97 through one Cooling air flow can be performed.
- the cup-shaped support shell 81 In the area between the hub 77 and the fan ring 79 is the cup-shaped support shell 81 provided with openings 97 so that the Fan ring 79 air both in the area of the air inlet 73 and in the Sucks area of the rear 87 of the housing 71.
- the in the field of Rear side 87 of the housing 71 is sucked in by the air flow Cross-sectional areas of between the cylindrical projection 91 and the pole ring 95 and between the pole ring 95 and the inner parts of the Drive motor 85 available air gaps 99 determined.
- the radial fan designed according to the invention has an improved one Efficiency, with the engine being cooled intensively. Even with tight Installation conditions in the motor vehicles according to the invention Lowering the component temperatures in the drive motor to an uncritical one Range achieved in such a way that the drive motors also have a long service life and thus the radial fan is achieved.
