Abstract
The invention relates to a by-pass ventilation system for an electric blower to cool engine compartment components in motor vehicles with a cooler (4), on the side of which away from the direction of travel (1) there is an air funnel (5), in the outlet of which is arranged an electric blower with a blower motor (9) and a ventilator turbine (10). On at least one side wall of the cooler (4) there is a bulkhead channel (6) open towards the direction of travel (1) which passes through the air funnel (5) on the casing surface and ends in the region immediately in front of the ventilator turbine plane in such a way that the largest part of the outlet cross-section (12) of the bulkhead channel (6) is covered by the rotating vanes of the ventilator turbine (10) and thus cold by-pass air is taken in by the electric blower and forced into the funnel-like transition (6'') behind the ventilator turbine plane with an air hose (7) as an extension to take the by-pass air (3) further to the engine compartment components.

Beschreibung 5Description 5
Die Erfindung betrifft ein Bypaßbeluftungssystem für Elektrogebläse zur Kühlung von Motorraumkomponenten in Kraftfahrzeugen mit einem Kühler, an dessen zur Fahrtrichtung abgewandten Seite ein Lufttrichter an- 10 geordnet ist, in dessen Auslaß ein Elektrogebläse mit einem Gebläsemotor und einem Lüfterrad angebracht ist.The invention relates to a bypass ventilation system for electric blowers for cooling engine compartment components in motor vehicles with a cooler, on the side facing away from the direction of travel an air funnel is arranged, in the outlet of which an electric blower with a blower motor and a fan wheel is attached.
Zur Kühlung von Motorraumkomponenten wie beispiels- 15 weise Ölbehälter, Getriebe, Ventildeckel oder Batte¬ rie ist es aus der DE-OS 41 02 645 bekannt, ein Ge¬ bläse durch die kinetische Energie der Abgase der Brennkraftmaschine nach Art eines Abgasturboladers anzutreiben. Es ist ferner bekannt, aus dem Luft- 20 trichter von sogenannten drückenden Gebläsen, d. h.For cooling engine compartment components such as oil tanks, gears, valve covers or batteries, it is known from DE-OS 41 02 645 to drive a fan by the kinetic energy of the exhaust gases of the internal combustion engine in the manner of an exhaust gas turbocharger.

Die-However, due to their location in front of the cooler, pressing fans cannot be geometrically large enough to make do with one electric blower, which is why two neighboring electric blower units are usually used in practice.

j Deshalb liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Kühlsystem für Motorraumkomponenten an¬ zugeben, das auf einfache Art und Weise mit geringem 35 Aufwand realisiert werden kann.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an mindestens einer Seitenwand des Kühlers ein in Fahrtrichtung geöffneter Schottkanal angeordnet ist, der den Lufttrichter an der Mantelfläche durchdringt und im Bereich unmittelbar vor der Lüfterradebene en¬ det, derart, daß der größte Teil des Auslaßquer¬ schnitts des Schottkanals von den rotierenden Flügeln des Lüfterrades überdeckt wird und dadurch kalte By- paßluft vom Elektrogebläse ziehend angesaugt wird und in den hinter der Lüfterradebene befindlichen trich¬ ter örmigen Übergang mit einem Luftschlauch als Fort¬ satz gedrückt wird zur Weiterleitung der Bypaßluft an die Motorraumkomponenten. j Therefore, the present invention has the object to provide a cooling system for the engine compartment components an¬ admit that can be realized in a simple manner with low overhead 35. This object is achieved in that at least one side wall of the cooler has a bulkhead channel which is open in the direction of travel and which penetrates the air funnel on the lateral surface and ends in the area immediately in front of the fan wheel plane, in such a way that the majority of the outlet cross section of the bulkhead duct is covered by the rotating vanes of the fan wheel and cold bypass air is drawn in by the electric blower and is pressed into the funnel-shaped transition behind the fan wheel plane with an air hose as a continuation for forwarding the bypass air to the engine compartment components.
In einer bevorzugten Ausführungsform sind Auslaßquer¬ schnitt und trichterförmiger Übergang zueinander ver¬ tikal durch ein Versatzstück versetzt, so daß die vektorielle Überlagerung von angesaugter Bypaßluft aus dem Auslaßquerschnitt und vom Lüfterrad beauf¬ schlagte Bypaßluft eine Resultierende ergibt, die überwiegend in den trichterförmigen Übergang weist. Um zu verhindern, daß sich relativ warme Kühlerabluft im Bereich des AuslaßquerSchnitts des Schottkanals mit kalter Bypaßluft vermischt, was die Kühlung der Motorraumkomponenten beeinträchtigt, ist im Auslaß des Lufttrichters parallel zur Lüfterradebene im Be¬ reich des Auslaßquerschnitts eine segmentartige Schottwand angebracht, die hälftig je oben und unten zu beiden Seiten des Auslaßquerschnitts warme Küh¬ lerabluft vom trichterförmigen Übergang weglenkt.In a preferred embodiment, the outlet cross section and the funnel-shaped transition from one another are vertically offset by an offset piece, so that the vectorial superimposition of the bypass air sucked in from the outlet cross section and the bypass air acted upon by the fan impeller gives a resultant which predominantly points into the funnel-shaped transition. In order to prevent relatively warm cooler exhaust air from mixing with cold bypass air in the area of the outlet cross section of the bulkhead duct, which impairs the cooling of the engine compartment components, a segment-like bulkhead wall is installed in the outlet of the air funnel parallel to the fan wheel plane in the area of the outlet cross section, half of which is at the top and directs warm cooler exhaust air away from the funnel-shaped transition on both sides of the outlet cross section.

Mit Bezugszeichen 1 ist die Fahrtrichtung gekenn¬ zeichnet. Die angesaugte Luft ist mit 2 gekennzeich¬ net , die durch den Kühler 4 strömt und als Haupt- luftstrom 8 durch das Lüfterrad 10 gelangt. Seitlich am Kühler 4 ist der Einlaß des Schottkanals 6, der die Bypaßluft 3 leitet und den Lufttrichter 5 an des¬ sen Mantelfläche durchdringt.The direction of travel is marked with reference number 1. The air drawn in is marked 2, which flows through the cooler 4 and passes through the fan wheel 10 as the main air flow 8. On the side of the cooler 4 is the inlet of the bulkhead duct 6, which guides the bypass air 3 and penetrates the air funnel 5 on its outer surface.
Im Auslaß des Lufttrichters 5 ist das Elektrogebläse mit dem Gebläsemotor 9 und dem Lüfterrad 10 ange- bracht. Der Schottkanal 6 endet im Bereich unmittel¬ bar vor der Lüfterradebene mit seinem Auslaßquer¬ schnitt 12. Hinter der Lüfterradebene befindet sich der trichterförmige Übergang 6' ' mit dem Luftschlauch 7 als Fortsatz, der die kalte Bypaßluft 3 an die zu kühlenden Motorraumkomponenten wie Batterie und/oder
elektronische Steuergeräte für das Motormanagement weiterleitet.The electric blower with the blower motor 9 and the fan wheel 10 is mounted in the outlet of the air funnel 5. The bulkhead duct 6 ends in the area immediately in front of the fan wheel level with its outlet cross section 12. Behind the fan wheel level is the funnel-shaped transition 6 ″ with the air hose 7 as an extension, which directs the cold bypass air 3 to the engine compartment components to be cooled, such as the battery and /or forwards electronic control units for engine management.
Trichterförmiger Übergang 6' und Auslaßquerschnitt 12 des Schottkanals 6 sind zueinander vertikal ver¬ setzt durch das Versatzstück 6', so daß die vektori- elle Überlagerung von angesaugter Bypaßluft 3 aus dem Auslaßquerschnitt 12 und vom Lüfterrad 10 beauf¬ schlagte Bypaßluft 3 eine Resultierende ergibt, die überwiegend in den trichter örmigen Übergang 6* • weist.Funnel-shaped transition 6 'and outlet cross-section 12 of the bulkhead duct 6 are vertically offset from one another by the offset piece 6', so that the vectorial superimposition of sucked-in bypass air 3 from the outlet cross-section 12 and bypass air 3 acted upon by the fan wheel 10 gives a resultant, which mainly points into the funnel-shaped transition 6 * •.
Der größte Teil des Auslaßquerschnitts 12 des Schott¬ kanals 6 wird von den rotierenden Flügeln des Lüfter- rades 10 überdeckt, wodurch kalte Bypaßluft 3 vomThe largest part of the outlet cross section 12 of the Schott¬ channel 6 is covered by the rotating blades of the fan wheel 10, whereby cold bypass air 3 from
Elektrogebläse ziehend angesaugt und in den trichter¬ förmigen Übergang 6* * gedrückt wird.Electric fan is drawn in and pressed into the funnel-shaped transition 6 * *.
Im Auslaß des Lufttrichters 5 ist parallel zur Lüf- terradebene im Bereich des Auslaßquerschnitts 12 die Schottwand 11 angebracht, die verhindert, daß heiße Kühlerabluft in den trichterförmigen Übergang 6• ' ge¬ langt. Die Schottwand 11 befindet sich hälftig je¬ weils oben und unten zu beiden Seiten des Auslaßquer- Schnitts 12, wie dies insbesondere Fig. 2 a verdeut¬ licht. Die Schottwand 11 ist vorzugsweise segmentar¬ tig ausgestaltet.In the outlet of the air funnel 5, the bulkhead 11 is installed parallel to the fan wheel plane in the area of the outlet cross section 12, which prevents hot radiator exhaust air from reaching the funnel-shaped transition 6 '. The bulkhead 11 is located in half at the top and bottom on both sides of the outlet cross section 12, as is particularly illustrated in FIG. 2 a. The bulkhead wall 11 is preferably designed as a segment.
Mit dem erfindungsgemäßen Bypaßbeluftungssystem las- sen sich prinzipiell alle kühlbedürftigen Motorraum¬ komponenten durch ein ziehendes Gebläse über entspre¬ chende Luftschläuche kühlen. Dementsprechend ist der Querschnitt des Schottkanals auszulegen. Auch sind mehrere Schottkanäle denkbar, die z. B. an beiden oder mehreren Seiten des Kühlers angebracht sind.
In principle, with the bypass ventilation system according to the invention, all engine compartment components requiring cooling can be cooled by means of a pulling fan via corresponding air hoses. The cross-section of the bulkhead duct must be designed accordingly. Several bulkhead channels are also conceivable, the z. B. are attached to both or more sides of the cooler.
