Abstract
Description
Die Erfindung betrifft ein Kraftfahrzeug mit einer Stirnwand nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a motor vehicle having an end wall after Preamble of claim 1.
Es ist allgemein bekannt, einen Luftstrom gezielt durch einen Motorraum eines Kraftfahrzeugs zu leiten, um entweder eine Brennkraftmaschine direkt zu kühlen, oder um über einen Wärmetauscher die Brennkraftmaschine zu kühlen. Der so erwärmte Luftstrom tritt hauptsächlich auf der Fahrzeugunterseite wieder aus dem Motorraum aus. Er trifft aber zumindest teilweise auch auf eine Stirnwand der Karosserie des Kraftfahrzeugs, die den Motorraum von der Fahrgastzelle abtrennt. Um zu vermeiden, dass sich die Stirnwand zu sehr erhitzt, ist auf der Stirnwand meist eine Wärmeisolierung angebracht.It is well known, a targeted air flow through an engine compartment a motor vehicle to either an internal combustion engine directly to cool, or to a heat exchanger to cool the internal combustion engine. The heated air stream occurs mainly on the underside of the vehicle again off the engine compartment. He meets but at least partially on one Front wall of the bodywork of the motor vehicle, which covers the engine compartment of the passenger compartment disconnects. To avoid the front wall too much heat, is on the front wall usually a thermal insulation appropriate.

Aufgabe der Erfindung ist es, ein Kraftfahrzeug so zu gestalten, dass eine Stirnwand der Karosserie des Kraftfahrzeugs sich nicht durch eine Wärmequelle in einem Motorraum stark aufheizen kann.task The invention is to make a motor vehicle so that a End wall of the body of the motor vehicle is not by a Heat source in an engine room can heat up strongly.
Diese Aufgabe wird mit einem Kraftfahrzeug mit einer Stirnwand mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is with a motor vehicle with an end wall with the Characteristics of claim 1 solved.
Erfindungsgemäß ist im mittleren Bereich vor einer Windschutzscheibe eine Einlassöffnung in einer Motorhaube vorgesehen ist, die den Motorraum auf der Oberseite begrenzt. Während der Fahrt wird durch die Einlassöffnung eintretende Umgebungsluft im Motorraum über die Wärmequelle zu zumindest einer seitlichen Auslassöffnung in der Motorhaube im Bereich einer A-Säule der Karosserie des Kraftfahrzeugs geleitet. Dabei wird der Umstand genutzt, dass sich im mittleren Bereich vor einer Windschutzscheibe während der Fahrt ein Überdruckgebiet bildet, während sich seitlich in den Bereichen nahe bei einer A-Säule ein Unterdruckgebiet bildet. Durch die Anordnung der Einlassöffnung in diesem Überdruckgebiet und der zumindest einen Auslassöffnung in diesem Unterdruckgebiet entsteht ein Luftstrom, der die Wärmequelle umströmt und so die Wärme abführt. Bevorzugt wird die Umgebungsluft im Motorraum zumindest teilweise durch einen Kanal geleitet, sodass sie die Wärmequelle möglichst gut umströmt. Der Kanal kann – verursacht durch Bauraumzwänge – auch nur bruchstückhaft ausgeführt sein. Günstigerweise sind beidseitig im Bereich der A-Säulen Auslassöffnungen vorgesehen.According to the invention in the middle area in front of a windshield an inlet opening provided in a hood, which covers the engine compartment on the top limited. While driving is through the inlet opening entering ambient air in the engine compartment via the heat source to at least one lateral outlet opening in the hood in the region of an A-pillar of the body of the motor vehicle directed. The fact is used, that in the middle Area in front of a windshield while driving an overpressure area forms while laterally in the areas near an A-pillar forms a negative pressure area. By the arrangement the inlet opening in this overpressure area and the at least one outlet opening in this negative pressure area creates an air flow, which flows around the heat source and so dissipates the heat. Preference is given to the ambient air in the engine compartment at least partially passed through a channel, so they the heat source flows around as well as possible. The channel can - caused by space constraints - even only be made fragmentary. Conveniently on both sides in the area of the A-pillars outlet openings intended.
Durch die Umströmung der Wärmequelle mit Umgebungsluft wird die entstandene Wärme zumindest teilweise abgeführt, sodass ein geringerer Wärmeeintrag in die umgebenden Bauteile erfolgt. Entsprechend erhitzt sich auch die Stirnwand der Karosserie des Kraftfahrzeugs weniger als bei einem Kraftfahrzeug ohne die erfindungsgemäße Kühlung der Wärmequelle mit Umgebungsluft. Somit ist beispielsweise auch bei einer Wärmequelle, wie bei einer Brennkraftmaschine mit einer V-förmigen Zylinderanordnung, bei der die Abgasturbolader und Katalysatoren im Bereich zwischen den Zylindern angeordnet sind, der Wärmeabtransport so hoch, dass auf eine Vergrößerung der Klimaanlage wegen des Wärmeeintrags verzichtet werden kann. Die Stirnwand erhitzt sich nicht mehr so stark, dass derartige Maßnahmen erforderlich wären. Auch kann der Wärmeeintrag in andere Bauteile so klein gehalten werden, dass bestimmte Grenztemperaturen, wie sie insbesondere bei Aluminiumstrukturen aus Gründen der Lebensdauer eingehalten werden müssen, sicher nicht überschritten werden. Im Gegensatz zu anderen Kühlmaßnahmen ist nicht zwingend der Einsatz einer Kühlvorrichtung mit bewegten Bauteilen, wie beispielsweise der Einsatz eines Lüfters, erforderlich, sodass die erfindungsgemäße Kühlung keinem Verschleiß unterliegt. Bevorzugt ist die Wärmequelle isoliert. Dadurch reduziert sich der Wärmeeintrag in die umgebenden Bauteile erheblich. Die Wärmemenge, die durch die Umgebungsluft abtransportiert werden muss, verringert sich.By the flow around the heat source with ambient air the resulting heat is at least partially dissipated, so that less heat input into the surrounding components he follows. Accordingly, the front wall of the body heats up as well of the motor vehicle less than in a motor vehicle without the Cooling of the heat source according to the invention with ambient air. Thus, for example, even with a heat source, like an internal combustion engine with a V-shaped cylinder arrangement, in which the turbocharger and catalytic converters in the range between the cylinders are arranged, the heat dissipation so high, that on an enlargement of the air conditioning can be dispensed with because of the heat input. The front wall does not heat up so much that such measures would be required. Also, the heat input be kept so small in other components that certain limit temperatures, as they are in particular with aluminum structures for reasons the lifetime must be adhered to, certainly not exceeded become. Unlike other cooling measures is not necessarily the use of a cooling device with moving components, such as the use of a fan, required so that the cooling according to the invention is not subject to wear. The heat source is preferred isolated. This reduces the heat input into the surrounding area Components considerably. The amount of heat due to the ambient air must be removed, decreases.
