Abstract

The application relates to a motor vehicle with a front face wall and a heating and/or ventilation and/or air-conditioning unit, the components of which are arranged on both sides of the face wall, the face wall having an air passage opening in this region. In order to keep the losses of strength on account of the air passage opening as low as possible, it is provided according to the invention that the face wall be designed with sieve-like perforations in the region of the air passage opening.

Description

"Kraftwagen mit einer vorderen"Motor vehicle with a front

Stirnwand" Die Erfindung betrifft einen Kraftwagen mit einer vorderen Stirnwand und einer Heizungs- und/oder Lüftungs- und/oder Klimaanlage, deren Komponenten beidseits der Stirnwand angeordnet sind, wobei die Stirnwand in diesem Bereich eine Luftdurchtrittsöffnung aufweist. Front wall "The invention relates to a motor vehicle with a front Front wall and a heating and / or ventilation and / or air conditioning system, their components are arranged on both sides of the end wall, the end wall in this area a Has air passage opening.

Bei Heizungen und Klimaanlagen moderner Bauart liegt die Luftansaugöffnung im hinteren Bereich der Motorhaube, meist als Spalt zwischen Motorhaubenende und Windschutzscheibe.In modern heating and air conditioning systems, the air intake opening is located in the rear area of the bonnet, usually as a gap between the bonnet end and Windshield.

Das Gebläse liegt unmittelbar darunter, also vor der Stirnwand, während das übrige Gehäuse von Heizung und Klimaanlage im Inneren des Fahrzeugs liegt.The fan is immediately below, so in front of the front wall, while the rest of the housing of the heating and air conditioning system is located inside the vehicle.

Das hat zur Folge, daß die Stirnwand eine entsprechend große Öffnung für den Luftdurchtritt bekommen muß. Diese Öffnung befindet sich in der Mitte des Fahrzeugs oberhalb vom Anschluß des Tunnels an der Stirnwand.As a result, the front wall has a correspondingly large opening must get for the passage of air. This opening is in the middle of the Vehicle above the connection of the tunnel to the bulkhead.

Bei Messungen zeigte sich, daß gerade dieser Bereich der Stirnwand eine große Bedeutung hinsichtlich der Steifigkeit und der Betriebsfestigkeit hat. Je größer die Öffnung ist und je näher sie sich am Anschluß des Tunnels an der Stirnwand befindet, desto größer ist der Verlust an Steifigkeit und Betriebsfestigkeit.Measurements showed that it was precisely this area of the front wall is of great importance in terms of rigidity and fatigue strength. The larger the opening and the closer it is to the connection of the tunnel to the end wall is located, the greater the loss of rigidity and fatigue strength.

Aufgabe der Erfindung war es, diesen Verlust wenigstens weitgehend zu verringern, ohne den Luftdurchsatz zu stören, d.h., daß der Luftdruck zur Beaufschlagung des Verdampfers bzw. Wärmetauschers durch Luftverwirbelungen nicht wesentlich gestört werden darf.The object of the invention was to at least largely reduce this loss without disturbing the air throughput, i.e. the air pressure to be applied of the evaporator or heat exchanger is not significantly disturbed by air turbulence may be.

Diese Aufgabe wird bei einem Kraftwagen der eingangs definierten Gattung erfindungsgemäß dadurch gelöst, daß die Stirnwand im Bereich der Luftdurchtrittsöffnung bzw.This task is performed in a motor vehicle of the type defined at the outset solved according to the invention in that the end wall in the area of the air passage opening respectively.

Öffnungen siebartig gelocht ausgebildet ist.Openings perforated like a sieve.

Dadurch wird die aus dem Gebläse austretende Luft gerichtet, so daß der hinter dem Lochbild liegende Verdampfer bzw.This directs the air exiting the fan so that the evaporator behind the hole pattern or

Wärmetauscher gleichmäßig beaufschlagt wird und Verwirbelungen vermieden werden, was dazu führt, daß mindestens dieselbe Luftmenge wie bei einer freien Öffnung durchtritt.The heat exchanger is applied evenly and turbulence is avoided which means that at least the same amount of air as with a free opening passes through.

Vorteilhafte Ausgestaltungen der Erfindung sind den weiteren Patentansprüchen zu entnehmen.Advantageous refinements of the invention are set out in the further claims refer to.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The object of the invention is to be based on one in the Drawing illustrated embodiment will be explained in more detail.

In der Zeichnung zeigen Fig. 1 eine Ansicht von vorn auf den Stirnwandbereich einer Rohbaukarosserie, und Fig. 2 eine Seitenansicht der Darstellung nach Fig. 1.In the drawing, FIG. 1 shows a view from the front of the end wall area a bodyshell, and FIG. 2 shows a side view of the illustration according to FIG. 1.

Der in der Zeichnung dargestellte Vorbaubereich eines Personen- oder Kombinationskraftwagens weist unterhalb eines Querträgers 1, oberhalb dessen eine Windschutzscheibe 2 angeordnet ist, eine Stirnwand 3 auf, die eine der Luftführung einer Heizungsanlage dienende Luftdurchtrittsöffnung 4 aufweist. Die Heizungsanlage besteht im dargestellten Ausführungsbeispiel aus einem vor der Stirnwand 3 angeordneten Gebläse 5 und einem hinter der Stirnwand angeordneten Wärmetauscher 6.The front building area of a person or area shown in the drawing Combination vehicle has below a cross member 1, above which one Windshield 2 is arranged, an end wall 3, which is one of the air ducts has a heating system serving air passage opening 4. The heating system consists in the illustrated embodiment of one arranged in front of the end wall 3 Fan 5 and a heat exchanger 6 arranged behind the front wall.

In die Luftdurchtrittsöffnung 4 ist ein Lochblech 7 eingesetzt, das siebartige Lochungen 8 aufweist und das fest, vorzugsweise durch Schweißen, mit der Stirnwand 3 verbunden ist.A perforated plate 7 is inserted into the air passage opening 4, which has sieve-like holes 8 and that firmly, preferably by welding, with the end wall 3 is connected.

In seinem unteren Bereich ist das Lochblech 7 - seitlich über zusätzliche Laschen 9 - auf einem Mitteltunnel 10 des Fahrzeugs abgestützt, während es oben mit dem Querträger 1 verbunden ist.In its lower area is the perforated plate 7 - laterally via additional Lugs 9 - supported on a center tunnel 10 of the vehicle while it is above is connected to the cross member 1.
